  The Norwegian Military Academy (NMA) aims at educating and developing highly skilled military officers through its Bachelor programs. Prior studies have indicated that twelve character strengths are particularly important for succeeding as a military officer. How important are these character strengths for how the military cadets perform academically and physically during the Bachelor’s programs at the NMA? The purpose of this study is to examine to what extent the twelve character strengths predict how well cadets succeed during their Bachelor programs, and if character strengths outperform mental intelligence as predictor of cadet performance. The cadets’ character strengths were measured with an observational instrument (OBSCIF) filled out by peer cadets at the end of a combat fatigue exercise. The cadets’ performance was measured by physical tests and grades from different courses of the Bachelor programs. Mental intelligence was measured as a general ability score, based on a combined measure of the performance on three tests: Arithmetic, Word Similarities and Figures. Analyses included partial correlations between the twelve character strengths and cadet performance indicators, controlling for mental intelligence. Ten out of twelve character strengths – Bravery, Love of learning, Leadership, Integrity, Perspective, Creativity, Self-regulation, Persistence, Open-mindedness, and Teamwork – correlated moderately to strongly with how the cadets performed either academically or physically, even when controlling for intelligence. The character strengths Fairness and Social intelligence did not correlate significantly with any of the performance criteria. Character strengths seem to be important predictors for how well cadets succeed during their Bachelor’s programs, and they outperform mental intelligence as predictors of cadet performance. Military education programs should consider selecting cadets characterized by certain character strengths, and aim at further developing these character strengths during the education.

  Problem statement: The Norwegian Military Academy (NMA) aims to educate highly competent officers, who have the capacity to lead under extreme conditions. Previous studies have identified 12 particularly important character strengths for succeeding as an officer in the Norwegian army. These are leadership, integrity, persistence, bravery, teamwork, fairness, open-mindedness, social intelligence, love of learning, perspective, self-regulation, and creativity. The NMA wants to observe, evaluate and develop these character strengths during the army cadets’ three-year bachelor’s program. However, a previous study has found that VIA-IS – a survey based questionnaire designed to measure character strengths – poorly predicts what character strengths army cadets actually display during extreme conditions, such as a long and stressful military field exercise. Hence, there is a need for a reliable and valid measure of character strengths displayed under extreme conditions. Purpose of study: To develop a reliable and valid observational instrument for measuring 12 character strengths displayed by army cadets under extreme conditions, such as stressful military field exercises. Method: An observational instrument (OBSCIF – OBServation of Character In Field) was developed and tested on 59 army cadets. The cadets evaluated themselves on VIA-IS and OBSCIF. Consistency between scoring on the two instruments, and scale reliabilities for OBSCIF, were examined. Conclusion: Scores on the 12 character strengths measured by VIA-IS and OBSCIF correlates substantially with each other, indicating that OBSCIF is a valid measure of the 12 character strengths. In addition, reliability coefficients (Cronbach’s alphas) estimated for the 12 scales in OBSCIF are all within acceptable levels, indicating that they provide reliable measures of the 12 character strengths. OBSCIF exists in Norwegian and English, and is available for use by any educational institution who is interested in evaluating character strengths displayed during live settings.

  Problem statement: The Norwegian Military Academy (NMA) educates cadets who will serve as officers in international military operations. Serving as an officer in such operations is often demanding, and requires that the officer exhibit certain personal strengths and characteristics. Applying assumptions and formulations based on Peterson and Seligman’s (2004) taxonomy of 24 character strengths, prior studies have identified 12 character strengths that are particularly relevant and important for succeeding as an officer in the Norwegian army. The character strengths are: leadership, integrity, persistence, bravery, citizenship, fairness, open-mindedness, social intelligence, love of learning, perspective, self-regulation, and creativity. The NMA have launched a project to find ways of observing, evaluating and developing these character strengths during the cadets’ three-year bachelor’s program. Since no instruments for observing and evaluating character strengths in live contexts exist today, the NMA developed an observer-based instrument for evaluation of character strengths in military field exercises. Purpose of study: To examine the consistency in evaluations across raters when using an observer-based instrument designed to measure 12 vital character strengths in cadets during military field exercises. Method: 60 cadets from the NMA attending a 5-day military field exercise were evaluated on 12 character strengths by three different sources: themselves, peer cadets and supervisors. Evaluations from the different sources were compared, and consistency across sources for each of the 12 character strengths, were examined. Conclusion: 7 of 12 character strengths (leadership, persistence, citizenship, social intelligence, love of learning, perspective, and self-regulation) showed significant and positive correlations between two or three of the evaluation sources. Peers and supervisors were more consistent in their evaluations of the cadets compared to peers/self-evaluation and supervisor/self-evaluation.

  The present study is based on the premise that the integration of ethnic minorities may involve more than the majority’s expression of tolerance. In order to promote inclusion, the majority may have to play a more active role in the integration process. We describe the development and validation of a new psychometric scale which assesses majority members’ attitudes toward their own proactive contribution to the integration of immigrants within three domains: cultural and structural efforts, and openness to diversity. The scale is investigated by analyses of internal structure and exploration of construct validity in relation to relevant social psychological and personality constructs in a sample of 486 Norwegian university students (28% male, mean age = 26.5, SD = 6.08). Factor analyses supported a unidimensional structure and the estimated reliability of an additive scale was satisfactory (Cronbach’s α = 0.91). The scale correlated negatively with measures of right-wing authoritarianism and social dominance orientation, and positively with global identity. It was weakly related to the personality traits agreeableness, intellect, extraversion, and conscientiousness. The potential utility of the scale in both applied and experimental social psychological studies are discussed.

  Students frequently show misconceptions regarding scientific psychology in general and basic concepts in behavior analysis in particular. We wanted to replicate the study by Lamal (1995) and to expand the study by including some additional statements. In the current study, the focus was on misconceptions about behavior analysis held by undergraduates, by students in a master program in behavior analysis, by teachers in university colleges, and by a group of students without any formal training in psychology. The results showed that participants in all groups showed misconceptions. Students in the master program held the fewest misconceptions, while traditional psychology students showed most misconceptions about behavior analysis. Factors that might influence number and resistance of misconceptions are discussed.

  This study assessed the construct validity of the circumplex model of the Inventory of Interpersonal Problems (IIP-C) in Norwegian clinical and non-clinical samples. Structure was examined by evaluating the fit of the circumplex model to data obtained by the IIP-C. Observer-rated personality disorder criteria (DSM-IV, axis II) were used as external correlates. The reliability of the IIP-C scales were acceptable and in the same range as in the original version. A multi-sample analysis strategy did not support an invariant circumplex model across the two groups. However, the estimated structures reflected mostly the same circular pattern of a quasi-circumplex model in the two groups. Departures from the ideal model were of negligible practical significance. The validity results examining personality disorder correlates of the IIP-C generally conformed to predictions, providing direct evidence for agreement between self-report and expert judgments of interpersonal problems.

  Abstract The effect of age was investigated in, and compared across, 16 automatically segmented brain measures: cortical gray matter, cerebral white matter, hippocampus, amygdala, thalamus, the accumbens area, caudate, putamen, pallidum, pons, cerebellar cortex, cerebellar white matter, the lateral ventricle, the inferior lateral ventricle, and the 3rd and 4th ventricle. Significant age effects were found for all volumes except pallidum and the 4th ventricle. Heterogeneous age responses were seen in that age relationships for cortex, amygdala, thalamus, the accumbens area, and caudate were linear, while cerebral white matter, hippocampus, pons, cerebellar white and gray matter, as well as volume of the lateral, inferior lateral, and 3rd ventricles showed curvilinear relationships with age. In general, the findings point to global and large effects of age across brain volumes.

  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.
