High school students aged 11-16 completed measures of body dissatisfaction (i.e., weight and muscle concerns) and appearance-related social pressure from peers and parents. Three aspects proved to be particularly crucial: Parental encouragement to control weight and shape was a strong predictor of weight concerns in boys and girls alike; influences of friends affected gender-specific body image concerns by leading to weight concerns in girls and muscle concerns in boys; finally appearance-based exclusion was a predictor of weight concerns in boys. The findings provide longitudinal evidence for the crucial impact of appearance-related social pressure and suggest that a detailed assessment of different types of social impacts can identify concrete targets for effective prevention and therapy for weight-related problems among adolescents.}, language = {en} } @article{KraheTomaszewska2011, author = {Krah{\´e}, Barbara and Tomaszewska, Paulina}, title = {Sexual scripts and the acceptance of sexual aggression in Polish adolescents}, series = {European journal of developmental psychology}, volume = {8}, journal = {European journal of developmental psychology}, number = {6}, publisher = {Wiley}, address = {Hove}, issn = {1740-5629}, doi = {10.1080/17405629.2011.611034}, pages = {697 -- 712}, year = {2011}, abstract = {A study with 199 Polish adolescents explored the prominence of risk factors of sexual aggression as part of the sexual scripts for consensual sexual encounters and as predictors of the acceptance of sexual aggression. Distinguishing between general scripts, attributed to the age group as a whole, and individual scripts, reflecting personal standards, sexual scripts were linked to the normative endorsement of the risk factors and to the acceptance of sexual aggression. Individual scripts contained fewer risk factors of sexual aggression than general scripts. The more prominently the risk elements featured in the individual (but not in the general) scripts, the more they were seen as acceptable. For boys, risk scores in individual scripts were correlated with sexual behaviour and linked to the acceptance of sexual aggression via their normative endorsement. The distinction between individual and general scripts as guidelines for behaviour is discussed in terms of its significance for the understanding of sexual aggression.}, language = {en} } @misc{SchiefeleSchaffnerMoelleretal.2012, author = {Schiefele, Ulrich and Schaffner, Ellen and M{\"o}ller, Jens and Wigfield, Allan}, title = {Dimensions of reading motivation and their relation to reading behavior and competence}, series = {Reading research quarterly}, volume = {47}, journal = {Reading research quarterly}, number = {4}, publisher = {Wiley-Blackwell}, address = {Hoboken}, issn = {0034-0553}, doi = {10.1002/RRQ.030}, pages = {427 -- 463}, year = {2012}, abstract = {This review of research examines the constructs of reading motivation and synthesizes research findings of the past 20 years on the relationship between reading motivation and reading behavior (amount, strategies, and preferences), and the relationship between reading motivation and reading competence (reading skills and comprehension). In addition, evidence relating to the causal role of motivational factors and to the role of reading behavior as a mediator of the effects of motivation on reading competence is examined. We identify seven genuine dimensions of reading motivation: curiosity, involvement, competition, recognition, grades, compliance, and work avoidance. Evidence for these dimensions comes from both quantitative and qualitative research. Moreover, evidence from previous studies confirms the positive contribution of intrinsic reading motivation, and the relatively small or negative contribution of extrinsic reading motivation, to reading behavior and reading competence. The positive contribution of intrinsic motivation is particularly evident in relation to amount of reading for enjoyment and reading competence and holds even when accounting for relevant control variables. However, the causal role of reading motivation and the mediating role of reading behavior remain largely unresolved issues.}, language = {en} } @article{MeckelmannPfeiferRauh2013, author = {Meckelmann, Viola and Pfeifer, Caroline and Rauh, Hellgard}, title = {Family relationships in childhood, pubertal timing, and subsequent reproductive strategies among adolescents}, series = {South African journal of psychology}, volume = {43}, journal = {South African journal of psychology}, number = {1}, publisher = {Sage Publ.}, address = {London}, issn = {0081-2463}, doi = {10.1177/0081246312474408}, pages = {22 -- 33}, year = {2013}, abstract = {The evolutionary theory of socialization of Belsky, Steinberg, and Draper was investigated on the empirical basis of a longitudinal sample of 26 adolescent girls and boys who were born in Berlin during German reunification, as well as their mothers.

The aim of the current study was to prospectively ascertain the relationship between age at first cigarette and initial smoking experiences, and to examine the combined effects of these characteristics of adolescent smoking behavior on adult smoking. It was hypothesized that the association between earlier age at first cigarette and later development of nicotine dependence may, at least in part, be attributable to differences in experiencing pleasurable early smoking sensations. Data were drawn from the participants of the Mannheim Study of Children at Risk, an ongoing epidemiological cohort study from birth to adulthood. Structured interviews at age 15, 19 and 22 years were conducted to assess the age at first cigarette, early smoking experiences and current smoking behavior in 213 young adults. In addition, the participants completed the Fagerstrom Test for Nicotine Dependence. Adolescents who smoked their first cigarette at an earlier age reported more pleasurable sensations from the cigarette, and they were more likely to be regular smokers at age 22. The age at first cigarette also predicted the number of cigarettes smoked and dependence at age 22. Thus, both the age of first cigarette and the pleasure experienced from the cigarette independently predicted aspects of smoking at age 22.}, language = {en} } @article{NikitopoulosZohselBlomeyeretal.2014, author = {Nikitopoulos, Joerg and Zohsel, Katrin and Blomeyer, Dorothea and Buchmann, Arlette F. and Schmid, Brigitte and Jennen-Steinmetz, Christine and Becker, Katja and Schmidt, Martin H. and Esser, G{\"u}nter and Brandeis, Daniel and Banaschewski, Tobias and Laucht, Manfred}, title = {Are infants differentially sensitive to parenting?

This paper documents the available evidence on the prevalence of sexual aggression perpetration and victimization from 27 EU countries, established as part of the Youth Sexual Aggression and Victimization (Y-SAV) project. A total of N = 113 studies were identified through a systematic review of the literature and consultations with experts in each country. Despite differences in the number of available studies, methodology, and sample composition, the review shows substantial prevalence rates of sexual aggression perpetration and victimization across Europe. A wide variation was found, both within and between countries. The lifetime prevalence rates of female sexual victimization, excluding childhood sexual abuse, ranged from 9 to 83\%, the rates of male sexual victimization ranged from 2 to 66\%, the rates of male sexual aggression ranged from 0 to 80\%, and the range of female sexual aggression ranged from 0.8 to 40\%. One-year prevalence rates showed a similar variability. Conceptual and methodological problems in the database are discussed, and an outline is presented for a more harmonized approach to studying the scale of sexual aggression among young people in Europe.

The purpose of the present cross-sectional study was to investigate whether these attributes are BE-specific and whether different patterns exist for boys and girls. We assessed BE, internalizing symptoms and psychological factors in 1039 adolescents from a community sample by self-report. Using multinomial logistic regression and controlling for measured height and weight, we compared adolescents with BE with individuals from a healthy control group and adolescents reporting internalizing symptoms. Individuals from the BE-group reported a greater lack of interoceptive awareness and higher body dissatisfaction than individuals from the healthy control group. Additionally, we found a significant interaction between gender and body dissatisfaction. Internalization of the societal body ideal was related to BE when compared to internalizing symptoms. Results suggest, that the lack of interoceptive awareness and body dissatisfaction display substantial associations with BE, and that the latter effect is especially strong in boys. The internalization of societal standards of beauty emerged as a BE-specific factor and this finding emphasizes the role of the societal body ideal in the nature of eating pathology in boys and in girls. Increasing body satisfaction and the acceptance of realistic body ideals might be effective strategies in preventing eating pathology.}, language = {en} } @article{BuchmannHohmWittetal.2015, author = {Buchmann, Arlette F. and Hohm, Erika and Witt, Stephanie H. and Blomeyer, Dorothea and Jennen-Steinmetz, Christine and Schmidt, Martin H. and Esser, G{\"u}nter and Banaschewski, Tobias and Brandeis, Daniel and Laucht, Manfred}, title = {Role of CNR1 polymorphisms in moderating the effects of psychosocial adversity on impulsivity in adolescents}, series = {Journal of neural transmission}, volume = {122}, journal = {Journal of neural transmission}, number = {3}, publisher = {Springer}, address = {Wien}, issn = {0300-9564}, doi = {10.1007/s00702-014-1266-3}, pages = {455 -- 463}, year = {2015}, abstract = {Enhanced endocannabinoid signaling has been implicated in typically adolescent behavioral features such as increased risk-taking, impulsivity and novelty seeking. Research investigating the impact of genetic variants in the cannabinoid receptor 1 gene (CNR1) and of early rearing conditions has demonstrated that both factors contribute to the prediction of impulsivity-related phenotypes. The present study aimed to test the hypothesis of an interaction of the two most studied CNR1 polymorphisms rs806379 and rs1049353 with early psychosocial adversity in terms of affecting impulsivity in 15-year-olds from an epidemiological cohort sample followed since birth. In 323 adolescents (170 girls, 153 boys), problems of impulse control and novelty seeking were assessed using parent-report and self-report, respectively. Exposure to early psychosocial adversity was determined in a parent interview conducted at the age of 3 months. The results indicated that impulsivity increased following exposure to early psychosocial adversity, with this increase being dependent on CNR1 genotype. In contrast, while individuals exposed to early adversity scored higher on novelty seeking, no significant impact of genotype or the interaction thereof was detected. This is the first evidence to suggest that the interaction of CNR1 gene variants with the experience of early life adversity may play a role in determining adolescent impulsive behavior. However, given that the reported findings are obtained in a high-risk community sample, results are restricted in terms of interpretation and generalization. Future research is needed to replicate these findings and to identify the mediating mechanisms underlying this effect.}, language = {en} }
