  Severe obesity has been associated with reduced performance on tests of verbal memory in bariatric surgery candidates. There is also some evidence that bariatric surgery leads to improved verbal memory, yet these findings need further elucidation. Little is known regarding postoperative memory changes in the visual domain and how patients subjectively experience their everyday memory after surgery. The aim of the current study was to repeat and extend prior findings on postoperative memory by investigating visual, verbal, and self-reported everyday memory following surgery, and to examine whether weight loss and somatic comorbidity predict memory performance. The study was a prospective, observational study in which participants (n = 48) underwent cognitive testing at baseline, 1 and 2 years after bariatric surgery. Repeated measures analyses of variance revealed significantly poorer visual and verbal memory performance at the 1-year follow-up, with performance subsequently returning to baseline levels after 2 years. Verbal learning and self-reported everyday memory did not show significant postoperative changes. Memory performance at 1 year was not significantly predicted by weight loss, changes in C-reactive protein levels or postoperative somatic comorbidity (Type 2 diabetes, sleep apnea, and hypertension). The study demonstrated poorer visual and verbal memory performance at 1-year follow-up that returned to baseline levels after 2 years. These findings are in contrast to most previous studies and require further replication, however, the results indicate that postoperative memory improvements following bariatric surgery are not universal. Findings suggest that treatment providers should also be aware of patients potentially having poorer memory at 1 year following surgery.

  The Breast Size Satisfaction Survey (BSSS) was established to assess women’s breast size dissatisfaction and breasted experiences from a cross-national perspective. A total of 18,541 women were recruited from 61 research sites across 40 nations and completed measures of current-ideal breast size discrepancy, as well as measures of theorised antecedents (personality, Western and local media exposure, and proxies of socioeconomic status) and outcomes (weight and appearance dissatisfaction, breast awareness, and psychological well-being). In the total dataset, 47.5 % of women wanted larger breasts than they currently had, 23.2 % wanted smaller breasts, and 29.3 % were satisfied with their current breast size. There were significant cross-national differences in mean ideal breast size and absolute breast size dissatisfaction, but effect sizes were small (η2 = .02–.03). The results of multilevel modelling showed that greater Neuroticism, lower Conscientiousness, lower Western media exposure, greater local media exposure, lower financial security, and younger age were associated with greater breast size dissatisfaction across nations. In addition, greater absolute breast size dissatisfaction was associated with greater weight and appearance dissatisfaction, poorer breast awareness, and poorer psychological well-being across nations. These results indicate that breast size dissatisfaction is a global public health concern linked to women’s psychological and physical well-being.

  Body image issues can affect all domains of sexual functioning. The aim of this study was to examine how, in a sociocultural context where physical and sexual attractiveness is equated with young and slim body ideals, appearance dissatisfaction and importance are related to sexual satisfaction in older adults in four European countries. A cross-sectional survey with probability samples of the population aged 60–75 years was used. Only respondents with a partner were included in this paper, and the countries included Norway (n = 957), Denmark (n = 846), Belgium (n = 612), and Portugal (n = 367). Sexual satisfaction, appearance dissatisfaction, and importance were assessed, and frequency of intercourse/kissing and cuddling, relationship satisfaction, age, and body mass index were all used as control variables. Belgian men scored significantly lower on sexual satisfaction, while there was no difference in sexual satisfaction in women. Appearance dissatisfaction was lower in Scandinavian women and men, and in Belgian men, and appearance salience was lower in Norwegian men and women, and in Portuguese women. Linear regression analysis revealed that, adjusting for confounders, appearance dissatisfaction was significantly related to sexual satisfaction in Scandinavian women and men, as well as in Belgian men. Compared to research on younger adults, appearance evaluation appeared to play an equally important role in sexual satisfaction in older adults in our study. The variation in appearance dissatisfaction in older adults across European countries is a novel finding that needs to be examined further.

  The aim of the study was to explore attitudes towards sexuality and sexual behavior in older adults in Norway, Denmark, Belgium, and Portugal. A cross-sectional survey with representative samples of the population aged 60–75 years recruited through phone registers in Norway (676 men and 594 women), Denmark (530 men and 515 women), Belgium (318 men and 672 women), and Portugal (236 men and 273 women) was conducted. The data collection was carried out using an anonymous postal questionnaire. Four dimensions of attitudes towards sexuality were identified: ‘sex for love’, ‘sexual pressure in society’, ‘sex for well-being’, and ‘sexual changes and ageing’. Discriminant analyses identified three discriminant attitude functions: sex for well-being, sexual changes due to ageing, and sex for love. Portuguese men had positive attitudes towards sex as good for well-being in older adults but believed ageing was an obstacle to being sexual at this stage of life. Portuguese women believed sex was good for well-being and did not consider ageing an obstacle to sexual enjoyment. Norwegian men and Danish women believed changes in sexuality due to ageing were no obstacle to being sexual but did not believe that sex was good for well-being. The attitudes of Belgian and Danish men were largely inclined in the direction that sex is not particularly important for elderly people and that changes in sexuality occur due to the ageing process. Men and women were committed to the attitude of sex for love, although this was observed most in Belgian participants and least in Danish men. Positive attitudes towards sex for wellbeing and towards ageing and sexual changes correlated with less change in sexual interest and sexual enjoyment, and with increased frequency of intercourse and masturbation. To tailor successful sexual health interventions, attitudes of sexuality in older people should be addressed.

  The aim of the current study was to explore whether developmental trajectories of body satisfaction from adolescence to young adulthood predicted measures of sexual satisfaction in young adulthood, even when controlling for important covariates such as gender, weight development, relationship status, mental health, and frequency of sexual intercourse and masturbation. Data were collected from a population-based prospective cohort of Norwegian adolescents (n = 2,587) over a period of 13 years in four waves (1992, 1994, 1999, and 2005; mean age = 14.9 in 1992, 57.3% women). Latent growth curves were estimated for body satisfaction and Body Mass Index (BMI). Men reported higher sexual satisfaction, sexual activity, baseline body satisfaction, and BMI than women. The developmental trajectories revealed a slight increase in body satisfaction and BMI from adolescence to young adulthood in both genders. Moreover, structural equation models showed that baseline body satisfaction in both genders predicted sexual satisfaction as a young adult, independent of relationship status and frequency of sexual activity. Neither the development of BMI nor of body satisfaction predicted sexual satisfaction. The results elucidate the vital role of body satisfaction in sexual satisfaction in adults and the importance of addressing body dissatisfaction in childhood.

  What is the prevalence of using the Internet for love and sexual activities among older adults across Europe, and what predicts such use? Data were collected in probability samples among populations aged 60–75 years in Norway (N = 1271), Denmark (N = 1045), Belgium (N = 991), and Portugal (N = 509) using postal questionnaires. A total of 36% of men and 15% of women reported having used the Internet for sex and love purposes, most often to watch pornography. The use of the Internet for various love and sex purposes was higher in participants who had a partner, who had masturbation activity and who were satisfied with their current level of sexual activity. Multivariate logistic regression analyses showed that use of the Internet to find committed partners, watch pornography, buy sex products or seek information or advice was lower in Portuguese men than men in Norway, Denmark, and Belgium. Tailored websites to promote both sexuality and how to preserve a committed relationship are likely to prove important for the aging population.

  Background: Most patients do not meet the recommended level of physical activity after bariatric surgery, and psychological factors underlying postoperative physical activity remain poorly understood. This study aimed at identifying self-regulatory predictors of physical activity after bariatric surgery. Methods: Questionnaire data including self-regulation variables and the short-version of the International Physical Activity Questionnaire were obtained in a prospective cohort of 230 patients 1 year after Roux-en-Y gastric bypass. The study sample consisted of participants consenting to wear an ActiGraph GT3X+ accelerometer for seven consecutive days, 18–24 months after surgery (n = 120). Results: A total of 112 participants with complete self-report data provided valid accelerometer data. Mean age was 46.8 years (SD = 9.3), and 81.3% was women. Preoperative and postoperative BMI was 44.8 ± 5.5 and 30.6 ± 5.0 kg/m2, respectively. Total weight loss was 28.9% (SD = 7.5). By objective measures, 17.9% of the participants met the recommended level of moderate-to-vigorous-intensity of physical activity of ≥150 min/week, whereas 80.2% met the recommended level according to self-reported measures. Being single, higher education level, and greater self-regulation predicted objective physical activity in multivariate regression analysis. Greater self-regulation also predicted self-reported physical activity. Weight loss 1 year after surgery was not associated with self-reported or objectively measured physical activity. Conclusions: Despite large differences between accelerometer-based and subjective estimates of physical activity, the associations of self-regulatory factors and weight loss with postoperative physical activity did not vary depending on mode of measurement. Self-regulation predicted both objective and self-reported physical activity. Targeting patients’ self-regulatory ability may enhance physical activity after gastric bypass.

  Background The experience of symptoms after bariatric surgery such as pain, dumping, and fatigue, may affect behavior, quality of life, and the need for health care consultations. Attention to and interpretation of symptoms are influenced by psychological and contextual factors. Prospective studies of psychological factors predicting physical symptom perception after bariatric surgery are scarce. Objectives To explore the association of preoperative negative affect, history of traumatic sexual and violent events, with frequency and intensity of self-reported symptoms, one year after Roux-en-Y gastric bypass (RYGB). Setting University hospital Methods Questionnaire data were collected before and one year after RYGB from 230 patients. Negative affect and stressful negative life events were measured preoperatively. The participants reported the number and degree of impact of various physical symptoms postoperatively. Results The most common symptoms reported to have a high impact on behavior were fatigue (32.8%), and dumping (28.4%). Reporting more symptoms was associated with preoperative anxiety (r = .22, p = .001), and number of stressful life events (r = .21, p = .002). Participants with a probable preoperative anxiety disorder reported higher impact of fatigue, pain, dumping, and diarrhea after surgery, while those with a probable mood disorder and history of traumatic events reported higher impact of dumping. Conclusion Preoperative anxiety symptoms and stressful experiences were associated with higher perceived impact of symptoms, such as dumping, fatigue, and pain after RYGB. Evaluation of psychological characteristics associated with symptom perception may be relevant during handling of symptoms not responsive to other treatment measures.

  ackground: Weight loss and weight loss maintenance vary considerably between patients after bariatric surgery. Postoperative weight gain has partially been explained by lack of adherence to postoperative dietary and physical activity recommendations. However, little is known about factors related to postoperative adherence. Objectives: The aim of this study was to examine psychological, behavioral, and demographic predictors of adherence to behavior recommendations and weight loss 1 year after bariatric surgery. Setting: Oslo University Hospital. Methods: In a prospective cohort study, 230 patients who underwent Roux-en-Y gastric bypass were recruited from Oslo University hospital from 2011 to 2013. They completed a comprehensive questionnaire before and 1 year after surgery. Weight was measured preoperatively, on the day of surgery, and 1-year postoperatively. Results: Mean body mass index was 44.9 kg/m 2 (standard deviation [SD] ¼ 6.0) preoperatively and 30.6 kg/m 2 (SD ¼ 5.2) 1 year after surgery. Patients lost on average 29.2 % (SD ¼ 8.2) of their initial weight. Predictors of dietary adherence were years with dieting experience, readiness to limit food intake, and night eating tendency. Preoperative physical activity and planning predicted postoperative physical activity whereas predictors of weight loss were higher frequency of snacking preoperatively, greater past weight loss, and lower age. Conclusion: Several preoperative psychological predictors were related to postoperative adherence to dietary and physical activity recommendations but were not associated with weight loss. Inter- ventions targeting psychological factors facilitating behavior change during the initial postoperative phase are recommended as this might improve long-term outcomes.

  During adolescence, romantic relationships are a key developmental milestone. Coupled with the increasing salience of appearance and social acceptance, adolescents with an appearance-altering condition may feel particularly vulnerable when it comes to romantic relationships. This study aimed to explore the prevalence of romantic experiences among adolescents with a cleft lip and/or palate (CL/P), and to investigate how these experiences could be related to depressive symptoms and global self-worth. The study included 661 Norwegian adolescents with CL/P, who were compared to a large national sample. The prevalence of romantic relationships was lower among adolescents with CL/P compared to the reference group, although the overall impact on depressive symptoms and global self-worth appeared to be low. This study is one of few to explore the impact of a congenital visible condition on experiences of romantic relationships and provides preliminary insight into a significant, yet complex topic.

  Background Little is known about the psychological prerequisites for weight loss maintenance after bariatric surgery. A first step in investigating whether existing knowledge of conservative weight loss treatment is applicable for lifestyle interventions postoperatively is to compare specific psychological characteristics at baseline. The aim of this study was to compare patients scheduled for bariatric surgery with patients receiving conservative treatment for morbid obesity on measures of behavioral and psychosocial characteristics considered predictors of their adoption of and adherence to long-term lifestyle recommendations. Methods Baseline clinical and questionnaire data from the prospective “Oslo Bariatric Surgery Study” were used to examine potential differences between bariatric surgery patients (n = 301) and patients receiving conservative weight loss treatment (n = 261). Results The surgical group was characterized by their younger age (43.8 vs. 46.2 years, p <0.01), higher percentage of women (79.1 vs. 70.1 %, p <0.05), and higher Body Mass Index (BMI; 45.0 vs. 41.9 kg/m2, p <0.001). A multiple logistic regression analysis, adjusting for group differences in BMI, gender, and age, showed that the surgical group had higher self-efficacy (Odds ratio; OR = 3.44, 95 % Confidence interval; CI 1.65, 7.14), more positive outcome expectations (OR = 1.53, 95 % CI 1.23, 1.89), and plans that were more explicit for changing their eating behaviors (OR = 1.80, 95 % CI 1.06, 1.93). The surgical patients were also less ready to change physical activity levels (OR = 0.59, 95 % CI 0.48, 0.73), had tried more types of unhealthy weight loss methods in the past (OR = 1.16, 95 % CI 1.01, 1.33), drank soda more frequently (OR = 1.24, 95 % CI 1.02, 1.50), had fewer binge eating episodes (OR = 0.38, 95 % CI 0.20, 0.71), and had more depressive symptoms (OR = 1.19, 95 % CI 1.09, 1.29). Conclusions Patients opting for bariatric surgery had more positive expectations of the treatment outcomes and stronger beliefs in their ability to achieve these outcomes. Those starting conservative treatment had stronger beliefs in readiness to change physical activity levels. Future studies should explore the effect of interventions for bariatric surgery patients, promoting postoperative physical activity and stress realistic outcome expectations. The potential effects of incorporating this knowledge in intervention strategies remain to be explored.

  Abstract Objective: To study the relationship between age, gender, body mass index (BMI), body image, and perceived intimacy with partner and sexual satisfaction in young Norwegian adults. Methods: A questionnaire survey was completed online by 27.2 % (n = 568) of a representative national web sample of 2,090 persons aged 18–29 years. Results: Women were more dissatisfied with their body than men and BMI increased with age. A negative body image correlated with BMI, particularly among women. There was no gender difference in reported sexual satisfaction and perceived intimacy with partner. The most important direct path leading to increased sexual satisfaction was from perceived intimacy with partner, followed by body image and age. By influencing body image, BMI and gender influenced sexual satisfaction indirectly. Being male increased the likelihood of having a positive body image, which in turn increased the likelihood of reporting being sexually satisfied. Additionally, a lower BMI increased the likelihood of being satisfied with one’s body, which in turn increased sexual satisfaction. Conclusion: Body image is clearly related to sexual satisfaction, particularly in women. However, body image is not associated with the perception of intimacy with one’s partner, which is the most important factor for feeling sexually satisfied.

  The purpose of this study was to investigate the hypothesis that the effect of body dissatisfaction on disordered eating behavior is mediated through self-esteem and depression. If the effect of body dissatisfaction on disordered eating can be explained by self-esteem and depression, treatment may benefit from focusing more on self-esteem and depression than body dissatisfaction. We also hypothesized body image importance to be associatedwith lower self-esteem, stronger symptomsof depression, andmore disordered eating. The results showed that the effect of body dissatisfaction on disorder eating was completely mediated, whereas the effect of body image importance was partly mediated. Both self-esteem and depression were significant mediators. Body image importance and self-esteem had a direct effect on restrained eating and compensatory behavior. Depression had a direct effect on binge eating. This effectwas significantly stronger amongwomen. Depression also had a direct effect on restrained eating. This effect was positive among women, but negative among men. The results support emotion regulation and cognitive behavioral theories of eating disorders, indicating that self-esteemand depression are the most proximal factors, whereas the effect of body dissatisfaction is indirect. The results point out the importance of distinguishing between different symptoms of bulimia. Depression may cause binge eating, but compensatory behavior depends on self-esteemand body image importance. The results suggest that women may turn to both binge eating and restrained eating to escape awareness of negative emotions, whereas men focus on eating to a lesser extent than women. Existing treatment focuses on eating behavior first and mechanisms such as self-esteem and depression second. The results from this study suggest that an earlier focus on self-esteem and depression may be warranted in the treatment of disordered eating.

  Objective:  Explore psychological functioning in adolescents with a cleft at age 16 from a broad perspective, including cognitive, emotional, behavioral, appearance-related, and psychosocial adjustment. High-risk groups were identified within each area of adjustment to investigate whether vulnerable adolescents were found across domains or whether risk was limited to specific areas of adjustment. Methods:  Cross-sectional data based on psychological assessments at age 16 (N = 857). The effect of gender, cleft visibility, and the presence of an additional condition were investigated on all outcome variables. Results were compared with large national samples. Measures:  Hopkins Symptom Checklist, Harter Self-Perception Scale for Adolescents, Child Experience Questionnaire, and Satisfaction With Appearance scale. Results:  The main factor influencing psychological adjustment across domains was gender, with girls in general reporting more psychological problems, as seen in reference groups. The presence of an additional condition also negatively affected some of the measures. No support was found for cleft visibility as a risk factor except for dissatisfaction with appearance. Correlation analyses of risk groups seem to point to an association between social and emotional risk and between social risk and dissatisfaction with appearance. Associations between other domains were found to be weak. Conclusions:  The results point to areas of both risk and strength in adolescents born with a cleft lip and/or palate. Future research should investigate how protective factors could counteract potential risk in adolescents with a cleft.

  In young people, interactions with horses may contribute to the development of social skills and self-efficacy. Our aim was to identify relationships between psychological variables and young people’s experience of activities with horses. Participants in this study were 13–15-year-old adolescents (n = 25), given a 4-month intervention consisting of weekly sessions of stable work and horse-back riding. We investigated the relationship between psychological variables from survey data with video-recorded behavioral observations during tasks and contact with horses. From the behavioral data, we calculated the frequency per hour of “trying again” when met with a challenge, as a measure of participants’ persistence in horse-related tasks. The number of times per hour that that participant initiated contact with the horse was used as a measure of frequency of physical contact (petting). We examined correlations between the change from early to late stages of the intervention in trying again during horse-related tasks and for physical contact and three psychological variables measured prior to the intervention: perceived social support, self-esteem, and general self-efficacy. We detected an association between lower pretest levels of perceived social support and general self-efficacy, and an increase during the intervention in persistence of trying again when met with challenges during tasks with the horse. In a linear regression analysis, controlling for initial levels of persistence during horse-related tasks, self-esteem, and self-efficacy, social support was the only unique predictor of an increase in persistence during the intervention. No association was found between the psychological variables and change in frequency of petting the horse. The results indicate that adolescents with lower levels of perceived social support at the start of the intervention showed greater increases in their persistence in trying again after being met with challenges during horse-related tasks. Since persistence is a central aspect in the development of mastery of tasks, the possible positive social impact of the horse/stable environment should be given more attention in future intervention research.

  This study examined the associations among the frequency of viewing Internet pornography, beliefs about how realistically pornography portrays sex, self-perceived effects of one’s pornography use, genital appearance satisfaction, and sexual self-esteem in young adults. Online data were collected from four convenience samples of university students from Norway and Sweden, members of a queer youth organization, and readers of an erotic magazine. Because of cultural similarities and the comparable magnitude and patterns of the bivariate correlations among the samples on the study variables, they were pooled into a single sample (N = 1,274). The majority of men (81.1%) and a minority of women (18.1%) reported at least weekly use of Internet pornography on their personal computers, whereas using a mobile phone or tablet was less common. Most of the participants had sought mainstream pornographic content. Those with a stronger belief in pornographic realism were more likely to perceive the effect of pornography use positively. A hypothesized relationship between self-perceived positive effects of pornography use and a higher level of sexual self-esteem was found for men but not for women. This result was partially due to higher satisfaction with genital appearance among the men who mainly watched mainstream pornography. Genital appearance satisfaction was linked to higher sexual self-esteem for women, but it was not related to the self-perceived effect of pornography use. The results indicate that pornography may expand personal sexual scripts for both men and women, and may have a positive, although modest, influence on the sexual self-esteem of young male adults.

  This study explores how body ideals are discussed among adolescent boys and girls in 5 mixed-gender focus groups (n = 37). The ways in which boys and girls talk about bodies differed clearly within the focus group conversations as well as in the everyday situations described in the interviews. The boys were more concrete in their description of ideal bodies in the focus groups but reported less engagement in everyday body talk. The study demonstrates that self-derogating “fat talk” is normative in the meaning “easy to fall into” but not normative in the meaning “approved of”: Fat talk is more or less required in some situations but not really appreciated. Both girls and boys agreed on this description of fat talk among girls. They also agreed that fat talk rarely occurred among boys. It was a general consensus that body issues are more sensitive and problematic for girls than for boys.

  Earlier studies have indicated that learning to handle a horse through tasks and activities can lead to a feeling of mastery which may have an impact on self-efficacy. The aim of this study was to examine how adolescents conducted horse-related tasks presented to them in an intervention in a farm environment, and whether there was a change during the intervention in persistence on tasks with the horse. Furthermore, we wanted to examine the behavior of the adolescents towards the horse and the response from the horse. Each participant was given an intervention once a week for approximately 16 weeks consisting of tasks with the horse, riding, grooming, and stable work. The sample presented in this study consisted of 29 participants who were successfully video-recorded in the beginning and at the end of the intervention. Petting the horse was the most frequent way of initiating contact with the horse, and the distributions of contact behaviors were the same at both time spots. The response of the horse was mainly neutral or positive. When participants did not succeed at their first attempt when trying to solve a horse-related task or an exercise during riding, their subsequent behavior was recorded as either trying again or not trying again. Early in the intervention, these two options were chosen with about the same frequency, while at the end of the intervention trying again was chosen significantly more often than not trying again. This was operationalized as an increase in persistence when having difficulties in solving tasks with the horse. The increased persistence late in the intervention in retrying tasks may indicate that the adolescents developed a feeling of mastery, which is an important factor in development of self-efficacy.

  The study investigates how body ideals are discussed and conceptualized among groups of Norwegian youth. Altogether 48 girls and 15 boys, most aged 17 years, took part in nine focus groups, in order to study subcultural body ideals. Major differences were found between east-end and west-end boys (representing socioeconomic differences), where the former were more concerned about being big. Even though the ideals were more or less the same across the groups, the ways of addressing, conceptualizing and discussing body ideals clearly differed between the groups. The analyses reveal that body talk within peer groups seems to contribute to define adequate levels of effort that should be put into reaching the dominating body ideal.

  Background: This study aims to investigate whether cosmetic surgery has an effect on an individual’s body image, general self-esteem, and psychological problems. Further tests were conducted to assess whether the extent of psychological problems before surgery influenced improvements in postoperative psychological outcomes. Methods: Questionnaire data from 155 female cosmetic surgery patients from a plastic surgery clinic were obtained before and approximately 6 months after surgery. The questionnaire consisted of measures on body image, self-esteem, and psychological problems. Pre- and postoperative values were compared. Pre- and postoperative measures were also compared with the data compiled from a representative sample of 838 Norwegian women, aged 22e55, with no cosmetic surgery experience. Results: No differences in psychological problems between the presurgery patient and comparison sampleswere found,whereas differences in body image and self-esteembetween the sample groups were reported in an earlier publication. Analyses further revealed an improvement in body image (satisfactionwith ownappearance) after surgery. A significant but rather small effect on self-esteem was also found, whereas the level of psychological problems did not change after surgery. Postoperative measures of appearance satisfaction, self-esteem, and psychological problems did not differ from values derived from thecomparison sample. Finally, fewpsychological problems before surgery predicted a greater improvement in appearance satisfaction and self-esteem after surgery. Conclusions: The study provides evidence of improvement in satisfaction with own appearance after cosmetic surgery, a variable that is thought to play a central role in understanding the psychology of cosmetic surgery patients. The study also points to the factors that surgeons should be aware of, particularly the role of psychological problems, which could inhibit the positive effects of cosmetic surgery.

  Few studies have tested potential explanatory mechanisms for the high stability of extraversion. In this study, the relationship between extraversion, appearance evaluation, and cosmetic surgery was investigated to examine such mechanisms. The ‘‘Big Five” personality traits were assessed in 155 female cosmetic surgery patients prior to and 6 months after surgery, as well as from a representative sample of 907 women. Patients showed higher extraversion scores prior to surgery than were found in the representative sample; further, extraversion scores increased after surgery, while the increase diminished when controlled for appearance evaluation. The results are in accordance with a transactional model, whereby extraverts engage in actions that reinforce extravert tendencies, which may account for the high stability of extraversion.

  Background. The present study investigates psychological factors expected to predict the motivation to undergo cosmetic surgery. It is hypothesized that body image, self-esteem, teasing history, acceptance of cosmetic surgery in the individual’s envi¬ronment and self-monitoring relate to cosmetic surgery motivation. Methods. Questionnaire data were obtained from 907 participants who responded to a survey distributed to a representative sample of Norwegian women aged 22 to 55. A second sample of 195 female pro¬spective cosmetic surgery patients was recruited from a plastic surgery clinic. Measures of the hypothesized predictor variables were obtained from both samples. Surgery motivation was operationalized in two different ways. First, the women in the first sample were asked to indicate if and they wished to undergo cosmetic surgery, such that women who wished to have surgery could be compared to those who did not. Second, prospective patients were compared to women from the first sample who indicated that they did not wish to have cosmetic surgery. Results. Analyses revealed all predictor variables but self-esteem to be related to either the wish or the decision to undergo surgery, or to both. Social acceptance of cosmetic surgery and body image showed to be the strongest predictors of cosmetic surgery motivation. Conclusion. The study gives new insights into psychological factors predicting cosmetic surgery motivation. Further, the influence of social factors on cosmetic surgery motivation is emphasized and it is suggested that these factors be included in future research designs.

  The purpose of the study was to describe and analyse the relationship between self-reported degree of sexual desire and selected social background factors, sexual experience and attitudes towards sexuality. In 1997, a random sample of 5000 persons (18-49 years) in Oslo was drawn from the population register to participate in a sexual behavior survey. Data collection was carried out by means of postal questionnaires. The response rate was 48%. More men than women reported that they felt sexual desire often. Self-reported degree of sexual desire was associated with gender, age, level of education, coital frequency, frequency of masturbation, erotic self-perception and attitudes towards sexuality. Pregnancy and breast-feeding were not associated with self-reported degree of sexual desire in this study. It is discussed how these results may be used in clinical treatment of patients with problems related to sexual desire.

  The knowledge of how self-efficacy works within sexual scripts is limited. In the context of sexual script theory, this paper aims at focusing on the relationship between contraceptive self-efficacy and the intention to use condoms among Norwegian adolescents. The data is based on a stratified sample of 920 adolescents aged 16-20 years in a Norwegian county. Data were collected by means of questionnaires. Fifty-two percent of girls and 41.4% of the boys had had coital experience. Girls reported somewhat higher contraceptive self-efficacy than boys did. This gender difference was mostly represented by the girls' belief in their capability to prevent undesired sexual intercourse, and their capability to use contraception in a situation where they were very sexually aroused. There was a clear connection between the adolescents' actual use of condoms at the most recent occasion of sexual intercourse and their intention to do so the next time. Boys who were in love with their partner were more likely to perceive themselves as capable of communicating with their partner about contraception in the sexual context, which in turn increased their intention of using condoms the next time. This may reflect boys acting in accordance with their sexual script. The girls' intention to use condoms the next time was not influenced by their contraceptive self-efficacy to the same degree as the boy's intention was. Acting within their sexual script and using oral contraceptives had greater influence on the girl's contraceptive self-efficacy than using a condom did. This study points to the importance of anchoring health preventive messages in the social and sexual realities of adolescents by focusing on the positive sides of sexuality.

  A school-based sex education program was developed in order to prevent sexually transmitted diseases and unwanted pregnancies. A Solomon Four-group design, with random assignment to the different conditions, was used to evaluate an intervention based on cognitive social learning theory and social influence theory. The main goal of the intervention was to increase use of condoms. A stratified sample of 124 classes (2411 students) was drawn at random from all the upper secondary schools (high-schools/colleges) in one county in Norway. The results indicate a consistent interaction between pretest and intervention, which seem to have an effect on condom use. Pretest or intervention alone did not contribute to this effect. The interaction effect appeared among the students with few sexual partners. Several possible explanations to the observed interaction effect and the implication for future interventions are discussed.

  The purpose of this study is to study alcohol consumption among Norwegian adolescents at their most recent experience of sexual intercourse. The material comprises a stratified sample of 920 adolescents aged 16-20 years in a Norwegian county (52,3% of the girls and 41,4% of the boys had coital experience). Data were collected by means of questionnaires; 21,0% of the adolescents reported sex under influence of alcohol. A logistic regression analysis showed that the best predictors of sex under influence of alcohol were intercourse location, sexual enjoyment and sexual intercourse motivated by "Don't know, it just turned out that way". Adolescents with their most recent experience of intercourse away from home, who had problems enjoying sex and/or who said it just turned out that way, were more likely than others to have had sex under the influence of alcohol. A multivariate logistic regression analysis showed that among adolescents who reported that the intercourse took place away from home, the odds ratio (OR) for sex under influence of alcohol increased by 8,7. Those who had consumed alcohol before sex, more often than non-drinkers, tended to enter into sexual intercourse motivated by factors external to their own person. This tendency was more pronounced among boys and girls.

  This paper discusses the impact of gender differences in sexual socialisation on early sexual experiences among Norwegian adolescents. The material comprises a stratified sample of 920 adolescents aged 16-20 years in a Norwegian county. Data were collected by means of questionnaires. Of the respondents, 55.5% were girls and 44.5% were boys. 52.3% of girls and 41.4% of the boys had coital experience. The most important reasons for not having had sexual intercourse were: waiting for the right person, not feeling ready, not having had the opportunity, and having to fall in love first. The most common reasons for having had the first sexual intercourse were being in love, curiosity/excitement, and sexual arousal. The findings from a discriminant analysis showed that emotional reasons were more important to girls than to boys, whereas boys seemed more practical in sexual matters than girls did. More boys than girls reported that the reason for having had their most recent intercourse was that the partner wanted it. This indicates that if girls do not want sex, boys are seldom the position to use pressure. Girls set the premises for sexual interaction, but are not as sexually skilled as boys are. The implications for AIDS preventive work are discussed.

  Objective The objective of this study is to investigate factors that affect the perception of physical appearance among Norwegian women. Attitude toward one�s own body can be divided in two parts: Body image orientation (cognitive/behavioral) is defined as how important one�s appearance is and Body image evaluation (affective) refers to the degree of satisfaction with own appearance (Cash, 1990). It is also hypothesized that evaluation of physical appearance will be closely connected to general self-esteem among women. Methods A random sample of n = 2,000 was drawn from all Norwegian women aged 22 to 55 years. The respondents received a questionnaire about cosmetic surgery, body image and several other psychological variables. Three subscales from the Multidimensional Body Self-Relations Questionnaire (Cash, 1990), containing body image orientation, body image evaluation and body area satisfaction were used in the analyses. Self-esteem was measured by using The Self-Esteem Scale (Rosenberg, 1965). Besides sociodemographic variables, the effect of BMI (Body Mass Index) and the degree of teasing about physical appearance as a child/teenager were used in the models. Results The response rate was 46 % (907 persons responded). Twenty-three percent had a negative body image evaluation. The respondents were most dissatisfied with their tummy and weight and most satisfied with their shoulders and hair. The body image evaluation got more positive with increased age and education, but there were no such differences in body image orientation. A linear multiple regression analysis was conducted with body image evaluation as the dependent variable. BMI and teasing were the most important predictors besides age and education. Body image orientation was not related to body image evaluation. In a final analysis self-esteem was introduced as the dependant variable. All the variables, except age, predicted self-esteem independently of body image evaluation, although the Beta�s were low. The best predictor was Body image evaluation (Beta= .49, p<.000). Discussion The results fit well to the stated hypothesis: Body image evaluation is closely connected to self-esteem. The thin body ideal in western society makes body weight an important factor in women�s evaluation in physical appearance and have a mediating effect on general self-esteem. Teasing about physical appearance in childhood and adolescence has a lasting effect on both the individuals� satisfaction with physical appearance and their general self-esteem. Women who views physical appearance as important can be both satisfied or dissatisfied with their appearance, explaining why these two domains are unrelated.

  Introduction This study investigates the relation between Norwegian women�s perception of their appearance and their motivation to undergo cosmetic surgery. Perception of one�s appearance can be divided in two parts: Perceived importance of own appearance and satisfaction with own appearance. It has been suggested that women take cosmetic surgery only when they are dissatisfied with their body and when their appearance is important for them. There are relatively few studies that have investigated this relation, and these studies have methodological shortcomings that may have biased their results. Methods A random sample of n = 2,000 was drawn from all Norwegian women aged 22 to 55 years. The respondents received a questionnaire about cosmetic surgery and several psychological variables. This presentation focuses on the questions � Have you ever taken cosmetic surgery?� and �How much do you wish to undergo cosmetic surgery?� (from �not at all� to �very much�). In addition, two scales from the Multidimensional Body Self-Relations Questionnaire, which contain appearance importance and appearance satisfaction, are used in the analyses. Results The response rate was 46 % (907 persons responded). Sixty-nine persons (7,7 %) indicated that they had undergone one or more cosmetic operations, while 24 % (203) indicated that they had not taken any operation, but wished to undergo cosmetic surgery (from �little� to �very much�). A multiple logistic regression analysis revealed that appearance importance, but not appearance satisfaction, was statistically significantly related to whether persons had taken cosmetic surgery or not. In addition, a linear multiple regression analysis were conducted with surgery motivation as dependent variable. Both appearance importance and appearance satisfaction were statistically significant predictors of this variable. Discussion The results fit well to the stated hypothesis: Women who whish to take cosmetic surgery are more devoted to their appearance and less satisfied with appearance than average. That already operated persons do not differ in appearance satisfaction from average, may be explained by cosmetic surgery�s positive effect on appearance satisfaction.

  Det overordnede tema i avhandlingen er forståelse av ungdommens prevensjonsbruk og hvordan slik atferd kan påvirkes ved hjelp av skolebasert seksualundervisning. Et intervensjonsprogram med målsetting å hindre spredning av seksuelt overførte sykdommer og uønsket graviditet ble utviklet og testet ut på videregående skoler. Doktoranden beskriver seksualundervisning i et historisk perspektiv og hvordan HIV/AIDS-epidemien i midten av 80-tallet økte behovet av effektiv seksualundervisning samtidig som prevensjonsmetoder som kondom får en større rolle i de ulike strategier for ¿sikker sex¿ som utvikles. Forskningsfeltet som denne avhandlingen er skrevet innenfor har høy aktualitet både i Norden og internasjonalt. Avhandlingen viser effekten av et undervisningsopplegg på kondombruk. Ungdommer mellom 16 og 20 år på videregående skole deltok i studien og 124 klasser ble tilfeldig fordelt i 4 ulike grupper i et eksperimentelt oppsett. Ved hjelp av spørreskjema ble effekten av undervisningsopplegget som 30 klasser gjennomgikk undersøkt 6 og 12 måneder etterpå og sammenlignet med kontrollklassene. Resultatet viste at bare gruppen som hadde deltatt både på pretest og undervisningsopplegget hadde en signifikant økning i kondombruk etter et halvt år. Effekten var størst blant de ungdommene med få seksualpartnere. Avhandlingen tar også for seg ulike faktorer som har sammenheng med samleie og prevensjonsbruk. For eksempel er det en sammenheng mellom ungdommenes opplevelse av å mestre selve situasjonen og økt prevensjonsbruk. De vanligste motivene for å ha samleie var forelskelse, nysgjerrighet/spenning og seksuell opphisselse. .Det å være forelsket ga guttene en opplevelse av å være kompetente når det gjaldt å kommunisere om prevensjon i den seksuelle situasjonen, som i sin tur økte intensjonen om å bruke kondom neste gang. Hver femte ungdom hadde erfaring av samleie under alkoholpåvirkning. Av disse var det færre som hadde brukt kondom sammenlignet med de som ikke hadde vært påvirket av alkohol. Avhandlingen understreker betydningen av å forankre forebyggende informasjon i ungdommenes egen sosiale og seksuelle virkelighet og av å fokusere på seksualitetens positive sider.

  Social networks are an important part of social support, which in turn is a central factor in coping. By creating arenas for students to meet each other early in the new term and using smaller groups it was hoped to instigate larger and qualitative better social networks among students at PSY110. The 100 students who wanted to participate in the study filled out the pretest questionnaire before they were randomly assigned to the experiment group (38 (74 %) women and 13 (26 %) men) or the control group (44 (90 %) women and 5 (10 %) men). The students in the experiment group were offered different voluntary activities: a peer support group, outing to the student¿s cottage, writing exercise seminar with smaller groups and more hours and additional training in study technique and time planning (compared to the ordinary seminars). The students in the experiment group experienced more wellbeing with the social environment, established more close relationships and acquaintances among the students at basic psychology during the fall term than the control group had done. The also reported more perceived social support from their teachers and other students, but not from their family, compared to the control group. It is possible to change the social environment in a positive direction at the course in basic psychology by implementing activities that do not require the allocation of big economic and/or personnel resources.

• Kvalem, Ingela Lundin (1999). Ensomhet. En utprøving av "Social and emotional loneliness scale". Show summary

  Bakgrunn: Måling av ensomhet springer rett ut fra konseptualiseringen av begrepet som enten et endimensjonalt eller flerdimensjonalt begrep. En av de mest brukte skalaene brukt for å måle ensomhet er den reviderte "UCLA Loneliness Scale" (Russell, Peplau & Cutrona, 1980). Denne skalaen ser på ensomhet som et endimensjonalt fenomen. Men ved faktoranalyser har det ofte vist seg at det fremkommer to meningsfulle dimensjoner, "nære andre" og "sosialt nettverk", som kan tyde på at ensomhet er et begrep med flere dimensjoner. Bygget på Weiss (1973) sin typologi av ensomhet som et todimensjonalt fenomen, har Wittenberg (1986) utviklet "Emotional versus Social Loneliness Scale". Skalaen er laget for å skille emosjonell isolering (mangel på nær tilknytning til et annet menneske) og sosial isolering (mangel på et nettverk av venner som deler felles interesser og aktiviteter). Formålet med denne fremstillingen er: 1. Å prøve ut en norsk oversettelse av "Emotional versus Social Loneliness Scale", for å se hvordan skalaen fungerer i et norsk utvalg. 2. Å undersøke i hvilken grad ensomhet, slikt det er målt her, begrepsmessig skiller seg fra selvfølelse og personlighet. Metode og materialer: Et spørreskjema ble sendt ut våren 1998 til 500 tilfeldig utvalgte studenter fra Odontologisk og Teologisk fakultet, Universitetet i Oslo. Svarprosenten var 49,7. "Emotional versus Social Loneliness Scale" består av 2x5 ledd med utsagn om kvaliteten på ens relasjoner. Responsen skåres fra 1 (Aldri) til 5 (Veldig ofte), hvilket gir en endelig sumskåre fra 5 til 25 på de to dimensjonene. Skalaen ble oversatt fra engelsk til norsk og tilbake igjen. Selvfølelse ble operasjonalisert ved "The Self-Esteem Scale" (Rosenberg, 1963) og personlighetstrekk ved en kortversjon av "The Big Five" (Engvik, 1999). Resultater: I en konfirmerende faktoranalyse (Varimax rotasjon) med 2 faktorer som kriterium plasserte seg leddene i forhold til de opprinnelige dimensjonene, sosial ensomhet og emosjonell ensomhet. Med Eigenverdi >1 som kriterium ble det tre ulike dimensjoner: kjæreste, nære venner og sosialt nettverk. De ulike egenskapene ved disse skalaene vil bli vist. Emosjonell ensomhet (EE) og Sosial ensomhet (SE) korrelerer .31 med hverandre. EE korrelerer rimelig høyt med (>.30) med Selvfølelse (.31), Dominans (-.35) og Varme (-.30), mens SE korrelerer med Selvfølelse (.42), Dominans (-.38). Konklusjon: Det ser ut til at det er rimelig begrepsmessig forskjell mellom emosjonell og sosial ensomhet. Den tredimensjonale skalaen hadde ikke noe bedre egenskaper enn den todelte i forhold til indre konsistens. Sosial ensomhet ligner litt på Selvfølelse i utformingen av utsagnene, hvilket kan forklare den nokså høye korrelasjonen mellom disse skalaen. Men da tilhørighet og tilbakemelding fra andre er nokså stor del av vårt selvbilde er det ikke så urimelig at det er en viss likhet. Hvis det er ulike dimensjoner i ensomhet vil det også være mulig å tenke seg ulike årsaker til og ulike tidsforløp på disse dimensjonene, og dermed få et instrument som lettere kan brukes som underlag for ulike tiltak.
