Optimism and Mental Health in Adolescence: a Prospective Validation Study of the Dutch Life-Orientation Test-Revised (LOT-R-A) for Adolescents

The study aimed to examine the psychometric properties of the Dutch Life Orientation Test-Revised for Adolescents (LOT-R-A), a self-report questionnaire assessing dispositional optimism, and to evaluate the two-factor structure (optimism, pessimism). The LOT-R-A and the questionnaires measuring well-being (MHC-SF-A) and psychological problems (SDQ) were completed by 459 Dutch adolescents (178 boys and 281 girls) between the ages of 11 and 18 years at baseline and 281 adolescents at a four-week follow-up. The results confirmed the two-factor structure (optimism, pessimism) of the LOT-R-A. The findings provided evidence of internal consistency of scores ranging from low to good, and evidence of good test-retest reliability of scores. Further, scores of optimism were cross-sectionally positively associated with scores of positive emotions and well-being and negatively with scores of psychological problems and negative emotions, providing evidence of convergent and divergent validity of optimism scores with emotions, well-being, and psychological problems. Lastly, scores of optimism were prospectively positively associated with scores of well-being and negatively with scores of psychological problems, providing evidence of criterion validity of optimism scores with well-being and psychological problems. Based on these findings it can be concluded that the LOT-R-A is a valid instrument to examine optimism among adolescents. Future research can help to elucidate the role of optimism in mental health interventions and can gather knowledge on how these interventions can be refined to optimally cultivate optimism during the developmental period of adolescence.     

Cross-cultural differences in academic self-efficacy and its sources across socialization contexts

Social Psychology of Education - This study investigated how as reported by Bandura (Self-efficacy: The exercise of control Freeman, 1997) sources of self-efficacy differ across socialization...     

Families of Choice? Exploring the Supportive Networks of Lesbians,Gay Men,and Bisexuals1

Despite the judicial and cultural progress that has been made in Flanders (i.e., Dutch‐speaking part of Belgium), lesbians, gay men, and bisexuals (LGBs) are still a stigmatized sexual minority. They are assumed to rely extensively on the support of friends to compensate for lack of familial support (i.e., family‐of‐choice hypothesis). In this article, we compare the support networks of 2,754 Flemish LGBs and 1,199 Flemish citizens and find convincing support for the family‐of‐choice hypothesis. LGBs seem to rely primarily on friends, while the average Fleming primarily relies on family for confidant support. We discuss the supportive potential captured in these friendship networks and raise the question “Are friends all a person needs?”     

Increased Stroop interference with better second-language reading skill

Skilled readers demonstrate remarkable efficiency in processing written words, unlike beginning readers for whom reading occurs more serially and places higher demands on visual attention. In the present study, we used the Stroop paradigm to investigate the relationship between reading skill and automaticity, in individuals learning a second language with a different orthographic system. Prior studies using this paradigm have presented a mixed picture, finding a positive, a negative, or no relationship between the size of Stroop interference and reading skills. Our results show that Stroop interference in the second language was positively related to reading skill (when controlled for interference in the first language). Furthermore, interference was positively related to objective but not subjective indices of the amount of exposure to the second language. We suggest that the lack of consistency in the results of earlier studies may be due, at least in part, to these studies looking at Stroop interference in isolation, rather than comparing interference between languages.     

Integrating different notions of employability in a dynamic chain: The relationship between job transitions,movement capital and perceived employability

This study connects different notions of employability with the ultimate aim to arrive at integration of a research field that has been criticized for being fragmented and fuzzy. We define employability as “an individual's chance of a job in the internal and/or external labor market”. Employability research assesses employability differently, looking at the realization of this chance (i.e., job transitions), personal strengths that increase this chance (i.e., movement capital) and appraisals of this chance (i.e., perceived employability). We hypothesize and establish in a two-wave sample of 643 Belgian (Dutch-speaking) employees that these different notions of employability form a dynamic chain, so that job transitions promote movement capital, which then affects perceived employability and ultimately feeds back to job transitions. Furthermore, we found that the internal labor market versus the external labor market are important foci in employability research since internal and external job transitions were found to relate differently to the other notions of employability.     

The psychology of psychiatric genetics: evidence that positive emotions in females moderate genetic sensitivity to social stress associated with the BDNF Val-sup-6-sup-6Met polymorphism

Previous work indicated protective effects of positive emotions on genetically influenced stress sensitivity. Given the fact that expression of brain-derived-neurotrophic-factor (BDNF) is associated with stress-induced behavioral changes, it was hypothesized that the BDNF Val-sup-6-sup-6Met genotype may mediate genetic effects on stress sensitivity, conditional on the level of concurrent positive emotions. Subjects (n=446) participated in a momentary assessment study, collecting appraisals of stress and affect in the flow of daily life. Multilevel regression analyses examined moderation of daily life stress-induced negative affect (NA) by BDNF genotype, and to what degree this was conditional on concurrent positive emotions. Results showed that heterozygous BDNF "Met" carriers exhibited an increased NA response to social stress compared with "Val/Val" subjects. Positive emotions at the time of the stressor decreased BDNF genetic moderation of the NA response to social stress in a dose-response fashion. This effect was most pronounced in BDNF Met carriers. Thus, the impact of BDNF genotype on stress sensitivity is conditional on the experience of positive emotions. Interdisciplinary research in psychology and psychiatric genetics may lead to the improvement of treatment choices in stress-related disorders.     

Transitioning between temporary and permanent employment: A two‐wave study on the entrapment,the stepping stone and the selection hypothesis

The present two‐wave study investigates how transitioning between temporary and permanent employment relates to a number of psychological consequences; namely, work engagement, affective organizational commitment, life satisfaction, and turnover intention. We hypothesize that temporary employment associates with unfavourable outcomes when it is a trap (entrapment hypothesis), while no such unfavourable outcomes are expected for those who transition to permanent employment (stepping stone hypothesis). Furthermore, we investigate the assumption that transitioning from permanent to temporary employment relates to unfavourable outcomes. Finally, we investigate dynamics related to selection into temporary or permanent employment. Hypotheses are tested on a sample of 1,475 workers. The results show that continuous temporary employment does not relate to unfavourable outcomes over time, while gaining permanent employment associates with increased work engagement. Also, permanent workers who transition to temporary employment are more engaged and committed after transitioning. No evidence for possible selection mechanisms is found.
