Distinguishing climate change worry from state climate anxiety across 32 countries: implications for subjective wellbeing. Journal of Environmental Studies and Sciences.

  The concepts of “climate change worry” and “climate change anxiety” are often used interchangeably in climate research, but they may reflect distinct emotional responses to climate change, which could potentially have different implications for public mental health. This research brief aims to empirically examine the differences between these two constructs by comparing their associations with key indicators of subjective wellbeing. Using survey data from 32 countries (N = 12,246), we compared how strongly climate change worry and state climate anxiety were each associated with subjective wellbeing, as measured by the WHO-5 Wellbeing Index and life satisfaction. State climate anxiety showed stronger associations with both WHO-5 Wellbeing Index and life satisfaction than climate change worry. This underscores the importance of treating the two as distinct emotional responses, each with different implications for public wellbeing. These insights are especially relevant for policymakers and climate communicators, who must carefully consider the emotional tone of climate messaging to foster constructive engagement while safeguarding the psychological wellbeing of the public.

  Internalizing problems, including symptoms of anxiety and depression, are common in childhood and adolescence and are linked to adverse long-term outcomes. Although both child genetic variants and parental genetic influences contribute to these problems, the specific direct (child) and indirect (parental) genetic pathways involved remain unclear. We applied multi-polygenic score models using elastic net regression to identify key genetic predictors of depressive and anxiety symptoms at ages 8 and 14 in 9,314 parent–child trios from the Norwegian Mother, Father and Child Cohort Study. We included 90 polygenic scores (PGSs) for the trio, along with their respective interaction terms. Predictive accuracy improved with age, with models explaining up to 2.7% of the variance in depression and 1.2% in anxiety. Key predictors included child attention deficit hyperactivity disorder, cognitive skills and well-being spectrum PGSs; maternal PGSs for smoking and cognitive skills; and paternal well-being spectrum PGSs. These findings underscore the value of incorporating diverse parental genetic traits to understand intergenerational risk transmission and developmental changes in child mental health.

  To our knowledge, few studies have attempted to explore the social perception of targets engaged in performance enhancement and body modification, and none has done so through a systematic review and meta-analysis. We conducted a meta-analysis on the social perception of anabolic-androgenic steroids (AAS), tattoo, and cosmetic surgery targets. Eligible experimental studies were identified through electronic database and ad hoc searches up to July 2025. We estimated effect sizes, in terms of the standardized mean difference, for the social perception ratings of the targets involved in the abovementioned practices on demographic, health, and psychosocial factors. Results from 34 studies with 9114 participants on AAS, tattoo, and cosmetic surgery were analyzed. Regarding performance enhancement, observers perceived the AAS (vs. no-AAS) target as less likely to display instrumental aggression, but having higher reactive aggression, lower sportspersonship, higher neuroticism, and lower agreeableness. Regarding body modification, the tattoo (vs. no-tattoo) target was perceived as more artistic, yet of a lower socioeconomic status, more offender typical and reoffend likely, and having lower hireability and competence. Furthermore, the cosmetic surgery (vs. no-cosmetic surgery) target was perceived as more attractive, approachable, trustworthy, and healthier, but also as less competent. Overall, observers show mixed perception of performance enhancement and body modification targets. The strong negative perceptions on competence, criminality, personality, and sportspersonship—especially considering the enhancement and modification overlap—highlight the extent of stigmatizing evaluation associated with these practices behaviours. Preventive, therapeutic, and occupational interventions may benefit from adjusting for the identified social perceptions.

  Recent cross-sectional and experimental research has found measures of climate change related distress to be positively associated with measures of efficacy beliefs. Authors of some of these studies have interpreted this finding in terms of motivated control, that is, people who experience climate change related distress are motivated to believe that they can help mitigate climate change. We extend this notion of motivated control by assuming that efficacy beliefs flowing from climate change related distress play a role in encouraging climate action. In two cross-sectional studies, we investigate this assumption: Study 1 used data from a multi-country study and found that negative emotions regarding climate change were positively associated with climate action and both individual and collective efficacy. Furthermore, we found evidence for an indirect effect of negative emotions on climate action via efficacy beliefs (individual and collective). Study 2 conceptually replicated this mediation effect, using data from a sample of citizens in Germany and a different measure of distress, focusing on climate change worry. Additional exploratory analyses revealed that the association with individual efficacy was stronger for more adaptive forms of climate change worry, compared to less adaptive forms. We conclude that our findings provide correlational support for motivated control being one of the psychological processes – and efficacy beliefs being one of the person-level factors – that account for adaptive behavioral reactions to climate change related distress. Experimental and longitudinal studies are needed to further substantiate this conclusion.

  Psychological studies on close relationships have often overlooked cultural diversity, dynamic processes, and potentially universal principles that shape intimate partnerships. To address the limited generalizability of previous research and advance our understanding of romantic love experiences, mate preferences, and physical attractiveness, we conducted a large-scale cross-cultural survey study on these topics. A total of 404 researchers collected data in 45 languages from April to August 2021, involving 117,293 participants from 175 countries. Aside from standard demographic questions, the survey included valuable information on variables relevant to romantic relationships: intimate, passionate, and committed love within romantic relationships, physical-attractiveness enhancing behaviors, gender equality endorsement, collectivistic attitudes, personal history of pathogenic diseases, relationship quality, jealousy, personal involvement in sexual and/or emotional infidelity, relational mobility, mate preferences, and acceptance of sugar relationships. The resulting dataset provides a rich resource for investigating patterns within, and associations across, a broad range of variables relevant to romantic relationships, with extensive opportunities to analyze individual experiences worldwide.

  Background: The present study aimed to explore women’s perception of men with different addictions in terms of their short- and long-term mate value. Objectives: 2,525 women (age range: 18–40, M = 28.35, SD = 6.39) were randomized to six conditions in a vignette-based experiment where a male of otherwise high mating value was described as suffering from either gambling, gaming, cannabis, anabolic androgenic steroid, and alcohol addiction or as not suffering from addiction (control). Results: Regarding long-term mate value of the target, the control target was rated higher than each of the targets. The gaming target was rated higher than the alcohol, cannabis, and gambling targets. Finally, the AAS target was rated as higher on long-term mate value than the alcohol and gambling addiction targets. Conclusions: Overall, women seem to perceive risk-taking in the face of uncertainty, reflected by gambling addiction, as an attractive behavioral tendency in men in terms of short-term mating. In contrast, potential long-term mates with gaming or chemical addictions are viewed more negatively, probably because it signals inadequate time and resources to be invested in a relationship.

  Objective: The present study investigates the longitudinal relationship between problematic gambling (PG) and the five factor model’s personality traits using autoregressive cross-lagged models. Methods: The data used in the current study was collected by a national survey in 2013 (n = 10,081) and a follow-up study (n = 5,848) in 2015. PG was measured using Canadian Problem Gambling Index (CPGI) while personality was assessed using Mini-International Personality Item Pool (MINI-IPIP). Participants who completed the CPGI and all the personality items during both waves (n = 2,702) were analysed. Results: The results show that neuroticism had positive cross-lagged associations with CPGI. In contrast, conscientiousness and agreeableness in 2013 were found to have inverse cross-lagged effect on CPGI in 2015. Finally, openness and extraversion did not have any cross-lagged associations with CPGI. Conclusion: PG poses serious negative implications for the involved individuals as well as their associated close social circle. Hence, it is important to understand predictors of PG for prevention purposes. Personality traits are one of the influential frameworks for examining uncontrolled psychopathological behaviors like PG. The study findings offer significant theoretical as well as practical implications.

  This study explored the correlates of climate anxiety in a diverse range of national contexts. We analysed cross-sectional data gathered in 32 countries (N = 12,246). Our results show that climate anxiety is positively related to rate of exposure to information about climate change impacts, the amount of attention people pay to climate change information, and perceived descriptive norms about emotional responding to climate change. Climate anxiety was also positively linked to pro-environmental behaviours and negatively linked to mental wellbeing. Notably, climate anxiety had a significant inverse association with mental wellbeing in 31 out of 32 countries. In contrast, it had a significant association with pro-environmental behaviour in 24 countries, and with environmental activism in 12 countries. Our findings highlight contextual boundaries to engagement in environmental action as an antidote to climate anxiety, and the broad international significance of considering negative climate-related emotions as a plausible threat to wellbeing.

  The Big Five Inventory-10 (BFI-10; Rammstedt & John, 2007) is one of many short versions of personality inventories that measure the Big Five trait dimensions. Short versions of scales often present methodological challenges as a trade-off for their convenience. Based on samples from 28 countries (N = 10,560), the current study investigated inter-item correlations estimated using Omega coefficients within each of the five personality characteristics measured by the BFI-10. Results showed that inter-item correlations were significantly lower, in the sample data from non-Western countries compared with the Western countries, for three of the five personality traits, specifically Conscientiousness, Extraversion, and Emotional Stability. Our findings indicate that the psychometric challenges exist across different cultures and traits. We offer recommendations when using short-item scales such as BFI-10 in survey research.

  Rationale Aggression and irritability are notable psychiatric side effects of anabolic-androgenic steroid (AAS) use. However, no previous study has systematically reviewed and quantitatively synthesized effects reported by experimental studies on this topic. Objective We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) investigating the effect of AAS administration on self-reported and observer-reported aggression. Methods Twelve RCTs comprising a total of 562 healthy males were identified through systematic searches of MEDLINE, PsycInfo, ISI Web of Science, ProQuest, Google Scholar, and the Cochrane Library. Results After excluding one outlier, AAS administration was associated with an increase in self-reported aggression under a random-effects model, albeit small (Hedges’ g = 0.171, 95% CI: 0.029–0.312, k = 11, p = .018), and when restricting the analysis to the effect of acute AAS administration on self-reported aggression under a fixed-effect model (g = 0.291, 95% CI: 0.014–0.524, p = .014). However, the above effects were neither replicated in the analysis of observer-reported aggression nor after restricting the analysis to the effects of the administration of higher (over 500 mg) and long-term (3 days to 14 weeks) doses. Conclusions The present meta-analysis provides evidence of an increase, although small, in self-reported aggression in healthy males following AAS administration in RCTs. Ecologically rational RCTs are warranted to better explore the effect of AAS administration on aggression in humans.

  Objectives: The aim of the present meta-analysis was to synthesize results from the association between problem gambling (PG) and dimensions of the five factor model of personality and to identify potential moderators (gambling diagnosis: yes/no, comorbidity: yes/no and trait assessment: four or fewer items vs. five items or more) of these associations in meta-regressions. Methods: Searches were conducted in six databases; Medline, Web of Science, PsychInfo, Google Scholar, OpenGrey, and Cochrane Library (conducted on February, 22, 2021). Included studies: (1) reported a relationship between PG and at least one of the personality traits in the five-factor model, (2) contained information of zero-order correlations or sufficient data for such calculations, and (3) were original articles published in any European language. Case-studies, qualitative studies, and reviews were excluded. All articles were independently screened by two authors. Final agreement was reached through discussion or by consulting a third author. Risk of bias of the included studies was assessed by the Newcastle-Ottawa Scale. Data were synthesized using a random effects model. Results: In total 28 studies, comprising 20,587 participants, were included. The correlations between PG and the traits were as follows: Neuroticism: 0.273 (95% CI = 0.182, 0.358), conscientiousness −0.296 (95% CI = −0.400, −0.185), agreeableness −0.163 (95% CI = −0.223, −0.101), openness −0.219 (95% CI = −0.308, −0.127), and extroversion −0.083 (95% CI = −0.120, −0.046). For all meta-analyses the between study heterogeneity was significant. Presence of gambling diagnosis was the only moderator that significantly explained between-study variance showing a more negative correlation to extroversion when participants had a gambling diagnosis compared to when this was not the case. Discussion: The results indicated some publication bias. Correcting for this by a trim-and-fill procedure showed however that the findings were consistent. Clinicians and researchers should be aware of the associations between personality traits and PG. Previous studies have for example showed neuroticism to be related to treatment relapse, low scores on conscientiousness to predict treatment drop-out and agreeableness to reduce risk of treatment drop-out.

  Climate change threatens mental health via increasing exposure to the social and economic disruptions created by extremeweather and large-scale climatic events, as well as through the anxiety associated with recognising the existential threat posedby the climate crisis. Considering the growing levels of climate change awareness across the world, negative emotions likeanxiety and worry about climate-related risks are a potentially pervasive conduit for the adverse impacts of climate change onmental health. In this study, we examined how negative climate-related emotions relate to sleep and mental health among adiverse non-representative sample of individuals recruited from 25 countries, as well as a Norwegian nationally-representativesample. Overall, we found that negative climate-related emotions are positively associated with insomnia symptoms and nega-tively related to self-rated mental health in most countries. Our findings suggest that climate-related psychological stressors aresignificantly linked with mental health in many countries and draw attention to the need for cross-disciplinary research aimed atachieving rigorous empirical assessments of the unique challenge posed to mental health by negative emotional responses toclimate change.

  The relationship between anabolic-androgenic steroid (AAS) use and aggression and psychological distress requires further elucidation. No previous study has examined whether the latent patterns of aggression and psychological distress are the same in male and female AAS users. Multigroup latent class analysis (MLCA) can be used to classify individuals into groups based on their responses on a set of variables, and to investigate measurement invariance across subgroups. We therefore conducted a MLCA to identify discrete subgroups of aggression and psychological distress in AAS users, and used measurement invariance to examine whether the identified subgroups can be applied to both sexes. We also examined the relationship between sex and subgroup belongingness. The sample comprised 206 AAS users (females = 58.30%) aged 14–56 (mean = 26.86, SD = 7.12) years. They completed questionnaires assessing demographics, AAS use, aggression, and psychological distress. Based on the MLCA, five subgroups were identified: high aggression moderate distress users (HAMoD: 07.63%), moderate aggression distress users (18.64%), moderate direct aggression-mild indirect aggression moderate distress users (22.95%), mild direct aggression-moderate indirect aggression-distress users (11.71%), and low aggression mild distress users (LAMiD: 39.06%). Although a homogenous five-class solution was the best model for both sexes, sex was significantly associated with the probability of subgroup membership. In particular, members of the HAMoD subgroup were more likely to be male whereas members of the LAMiD subgroup were more likely to be female. Our study provides novel empirical evidence of the idiosyncratic patterns of aggression and psychological distress among male and female AAS users.

Fulltekst i vitenarkiv Vis sammendrag

  Tools for reliable assessment of socially sensitive or transgressive behavior warrant constant development. Among them, the Crosswise Model (CM) has gained considerable attention. We systematically reviewed and meta-analyzed empirical applications of CM and addressed a gap for quality assessment of indirect estimation models. Guided by the PRISMA protocol, we identified 45 empirical studies from electronic database and reference searches. Thirty of these were comparative validation studies (CVS) comparing CM and direct question (DQ) estimates. Six prevalence studies exclusively used CM. One was a qualitative study. Behavior investigated were substance use and misuse (k = 13), academic misconduct (k = 8), and corruption, tax evasion, and theft (k = 7) among others. Majority of studies (k = 39) applied the “more is better” hypothesis. Thirty-five studies relied on birthday distribution and 22 of these used P = 0.25 for the non-sensitive item. Overall, 11 studies were assessed as high-, 31 as moderate-, and two as low quality (excluding the qualitative study). The effect of non-compliance was assessed in eight studies. From mixed CVS results, the meta-analysis indicates that CM outperforms DQ on the “more is better” validation criterion, and increasingly so with higher behavior sensitivity. However, little difference was observed between DQ and CM estimates for items with DQ prevalence estimate around 50%. Based on empirical evidence available to date, our study provides support for the superiority of CM to DQ in assessing sensitive/transgressive behavior. Despite some limitations, CM is a valuable and promising tool for population level investigation.

  Background: Physical attractiveness is a major motive for anabolic-androgenic steroid (AAS) use. Since majority of AAS users are men, we investigated heterosexual women’s ratings of the physical, sexual and romantic attractiveness of AAS-using and non-using men. Methods: A sample of 112 AAS-non-using heterosexual women (age range: 15–81, M = 29.61 years) was randomized to two independent conditions: food (n = 50) and AAS (n = 62). After exposure to a vignette (varied in AAS use or food consumption) and the target image of a moderately muscular man (same across conditions), participants in both conditions rated their respective target on physical, short-term sexual, and long-term romantic attractiveness. We compared ratings of the two targets using an independent t-test. Results: Compared to the non-using target, the AAS-using target received lower ratings (t = −2.61, p < .05, Cohen’s d = 0.50) on long-term romantic attractiveness. Conclusion: Heterosexual women rate perceived AAS-using men as less attractive for long-term romantic relationships. Preventive and harm reduction interventions may benefit from highlighting this finding.

  Background: There is a dearth of longitudinal studies on risk factors for anabolic–androgenic steroid (AAS) use and intent. Objectives: We conducted a longitudinal investigation of factors associated with AAS use intent from age 18 to 19, examining particularly the role of physical and verbal aggression. A sample of Norwegians completed questionnaires containing demographic, AAS use and intent, other addictions, aggression, and health measures at ages 18 (N = 1333, females = 58.9%) and 19 (N = 1277, females = 61.7%). The data were analyzed using descriptive statistics, correlations, and hierarchical multiple regression. Results: Results show that AAS use prevalence increased from 1 person at age 18 to 4 persons at age 19. Intent to use AAS, being male, living alone, and AAS use (all at 18 years) were associated with higher AAS use intent at 19 years. We found no associations between physical or verbal aggression and AAS use intent from ages 18 to 19.
