Genetic and environmental sources of continuity and change in teacher‐rated aggression during early adolescence

Genetic and environmental sources of continuity and change in aggression were studied in a sample of 1,041 twin pairs (364 monozygotic; 348 same‐sex dizygotic; and 329 opposite‐sex dizygotic) as part of an ongoing, population‐based Finnish twin‐family study. At ages 12 and 14, the twins' aggression was assessed by their classroom teachers, using a rating form of the Multidimensional Peer Nomination Inventory. Genetic and environmental sources of continuity and change were studied by fitting a longitudinal bivariate Cholesky decomposition model. Longitudinal model‐fitting results indicated that both genetic and environmental factors influenced continuity in aggression during this 2‐year period, but the age‐to‐age correlation of these factors differed by sex. Continuity in boys' aggression was mediated by genes and common environmental factors; in girls, in contrast, continuity was due primarily to common environmental, and to a lesser degree, unique environmental factors. Genes and unique environments contributed to change in aggression in both sexes. Aggr. Behav. 31:1–13, 2006. © 2006 Wiley‐Liss, Inc.     

Associative symmetry versus independent associations in the memory for object-location associations

The formation of associations between objects and locations is a vital aspect of episodic memory. More specifically, remembering the location where one experienced an object and, vice versa, the object one encountered at a specific location are both important elements for the memory of an event. Whether episodic associations are holistic representations of individual components or whether there are unidirectional, separately modifiable connections between them has been investigated nearly exclusively using verbal stimuli. A preliminary conclusion concerning this controversy is that verbal associations are, at least, highly correlated (M. J. Kahana, 2002). This theoretical debate, which in the past has undergone a major empirical effort, is still of relevance for the concurrent global matching models of associative memory (S. E. Clark & S. D. Gronlund, 1996). The authors used variations of a novel object-location learning paradigm to complement the accumulated evidence regarding the nature of episodic associations.     

Adolescents' views on war and peace in the early phases of the Iraq conflict

Adolescents' views of war and peace were assessed among 209 children aged 10-14 who attended a parochial school or its after-school religious program located in a predominantly middle-class, suburban area within commuting distance of New York City. Findings were compared to those of youth surveyed during other armed conflicts, specifically the Vietnam War, the first Persian Gulf War, and the U.S. military involvement in Latin America. The study took place in early fall 2003, and results were interpreted in light of the social climate and complex realities of post 9/11 in New York State, the Catholic Church's initial opposition to the Iraq conflict, and popular opinion. In spite of differences between the Iraq War and other conflicts, findings are remarkably similar. Although the present group is highly preoccupied with terrorism and nuclear war, even in a time of war, participants show concern for what they perceived as affecting their lives directly, rather than with conventional war. While they believe that President Bush was honest about the war in Iraq and right in sending troops, they do not glorify war. On a theoretical level, they overwhelmingly believe that wars are bad and the majority is optimistic that world peace is possible, though they realize that wars are difficult to prevent, believe that they are sometimes needed, and will occur in the future. Unlike the Catholic group surveyed by Tolley during the Vietnam War, however, participants are not as ready to die for their country, although findings show that, overall, like past groups, more boys tend to be pro-war than are girls and participants' views tend to reflect contemporary public opinions.     

Results of an Intervention for Individuals and Families with <Emphasis Type="Italic">BRCA</Emphasis> Mutations: A Model for Providing Medical Updates and Psychosocial Support Following Genetic Testing

Providing medical management updates and long-term support to families with hereditary cancer syndromes in rural areas is a challenge. To address this, we designed a one-day retreat for BRCA1/2 carriers in our region. The retreat included educational updates about medical management, genetic privacy and discrimination, and addressed psychological and family issues. Evaluations completed at the conclusion of the retreat were overwhelmingly positive with requests for a similar event in the future. The impact of this retreat on a variety of health behaviors was assessed. Eligible participants completed questionnaires before and 6 months after the retreat. Questionnaires focused on lifestyle, cancer screening and prevention practices, psychological history and distress, decision-making regarding genetic testing, and family communication issues. For individuals who completed both the pre and post retreat questionnaires, one-half made lifestyle changes and nearly two-thirds increased cancer screening, initiated chemoprevention, completed or planned to complete preventative surgery in the future. We conclude that this type of forum provides a valuable opportunity for BRCA carriers and their families to receive updated medical information, share personal experiences, provide and receive support, as well as change health behaviors.     

What matters most? The relative role of mentoring and career capital in career success

This study used a career capital framework to compare the relative role of mentoring and three other forms of career capital (human, agentic, and developmental network capital) in predicting career success. Using a three-wave longitudinal design we found that mentoring added value, above and beyond the other forms of career capital, in predicting promotions and advancement expectations. However, although mentoring mattered for career success, it represented just a part of a constellation of career resources that are embedded within individuals and their relationships. Implications for future research are discussed.     

Evaluating the invariance and validity of the structure of dysfunctional attitudes in an adolescent population

Form A of the Dysfunctional Attitude Scale (DAS-A), a self-report measure of depressive beliefs, is widely used to test Beck's cognitive model of depression. The present study is the first to evaluate the DAS-A factor structure in an adolescent population of 542 high school juniors and the first to examine a hierarchical model. Findings support the existence of a hierarchical structure consisting of two conceptually meaningful group factors (Dysfunctional Attitudes About Achievement and Dysfunctional Attitudes About Needing Approval), a method factor consisting of reverse-worded items, and a general factor, which accounts for 65% of the variance in total scores. The general factor is related to sociotropy, autonomy, and neuroticism, whereas the Dysfunctional Attitudes About Achievement and Dysfunctional Attitudes About Needing Approval factors demonstrate convergent and discriminant validity with respect to autonomy and sociotropy. The structure displays partial metric invariance in female and male students as well as in Caucasian and Non-Caucasian students.     

Testing the feasibility of developmental asset measures on college students to guide health promotion efforts

The purpose of this investigation was to assess the reliability and validity of eight developmental asset measures among a stratified, random sample (N = 540) of college students to guide health promotion efforts. The sample was randomly split to produce exploratory and confirmatory samples for factor analysis using principal axis factoring and varimax rotation and structural equation modeling techniques. Items were retained on factors if they had high loadings greater than .40 and were not complex. Concurrent validity was examined among substance use (including alcohol and tobacco) and sexual risk-taking variables. Exploratory and confirmatory samples did not differ on demographics. Parallel analysis confirmed the eight theorized constructs. Exploratory factor loadings were greater than .40. Concurrently, validity analyses were in the predicted direction. Cronbach alphas were .70 or greater with the exception of the Future Aspirations asset. Preliminary analyses support the reliability and validity of measuring developmental assets among emerging adults. Implications and potential uses are discussed.
