Although great strides have recently been made in our understanding of relational aggression and its consequences, one significant limitation has been the lack of prospective studies. The present research addressed this issue by identifying and assessing groups of relationally aggressive, physically aggressive, relationally plus physically aggressive (co-morbid), and nonaggressive children during their third grade year in elementary school and then reassessing them a year later, during fourth-grade (N = 224, 113 girls). Two aspects of social-psychological adjustment were assessed during both assessment periods including internalizing difficulties (i.e., withdrawal, depression/anxiety, and somatic complaints) and externalizing problems (i.e., aggressive behavior, delinquency). It was revealed that the strongest predictor of future social-psychological adjustment problems and increases in these problems from third to fourth was the combination of relational and physical aggression. Relational aggression also contributed unique information, relative to physical aggression, in the prediction of future maladjustment. Implications of these findings for future research and prevention efforts, particularly for aggressive girls, are discussed.

Adolescents in junior high school (n = 237), completed a questionnaire on bullying as it relates to victim and to perpetrator status, suicidality and biographical data. Psychological symptoms were assessed by the Youth Self Report (YSR) and the Depression Self-Rating Scale (DSRS) supplemented by school health officers blind assessments. Bullying was common: bully only (18%), victim only (10%) and victim and bully (9%). Bullies had mainly externalizing symptoms (delinquency and aggression) and those of the victim and bully group both externalizing and internalizing symptoms as well as high levels of suicidality. Adolescents in the bully only group were more likely to be boys and to have attention problems. Moreover, a substantial proportion of the adolescents in the victim only group were judged by school health officer to have psychiatric symptoms and to function socially less well.

The purpose of this study was to explore ethnic and generational influences among Chinese, Filipino, and Euro American adolescents on emotional distress and risk behaviors. Hierarchical multiple regression analyses were conducted with 216 Chinese, 387 Filipino, and 400 Euro American adolescents from the National Longitudinal Study on Adolescent Health to investigate the influence of ethnicity on depression, somatic symptoms, delinquency, and substance use; and to examine the influence of generation on the outcome variables among Chinese and Filipino American adolescents. Ethnicity predicted depression and delinquency scores, while generation within ethnic groups predicted somatic symptoms and substance use. The findings diverge from theories using acculturation as an explanatory mechanism for distress and risk behaviors and underscore the importance of examining sub-groups and generations of Asian American youth.

Drawing on a sample of 726 non-clinical adolescents (aged 17-18 years) from high schools in Ankara, Turkey, this paper primarily aims to identify the risk factors related to situational run away behavior. This study was based on an ecological risk factors model and tried to discover the associations for runaways. Run away behavior is one of the problematic behaviors very commonly seen among Turkish adolescents. Regression analyses revealed that predictors for runaway behavior differed due to gender; while, delinquency, sexual intercourse, substance use, parental separation and suicidal ideation were the significant predictors for girl adolescent runaway behaviors, while lack of parental support and depression were the significant predictors for boy adolescent runaway behavior.

To examine the behavioral and emotional difficulties of 73 children and adolescents with Prader-Willi Syndrome (PWS), mental retardation-only, and dual diagnosis (i.e., mental retardation and psychiatrically disordered) on the Devereux Scales of Mental Disorders (DSMD: Naglieri, LeBuffe, & Pfeiffer, Devereux Scales of Mental Disorders (DSMD) San Antonio, TX: PsychCorp 1994). Multivariate analyses and "Italic">d-ratios were computed to assess the statistical and clinically meaningful differences between pairs of samples. The PWS sample exhibited statistically significant higher levels of psychopathology than the mentally-retarded-only sample on the Total, Externalizing, Internalizing, Attention/Delinquency, Conduct, Anxiety, and Acute Problems Scales. When compared to the dually-diagnosed sample, children with PWS Syndrome had comparable levels of psychopathology, but lower levels of depression. Results revealed that PWS represents a highly unique and complex psychological disorder with multiple areas of disturbances.

Using data from Waves 1 and 2 of the National Longitudinal Study of Adolescent Health, I extend prior research on family transitions and adolescent well-being by examining the influence of parental marital and cohabitation transitions on adolescent delinquency, depression, and school engagement. Adolescents who experienced a family transition reported decreased well-being, on average, relative to those in stable, two-biological-parent families. Specific comparisons of various types of family stability and change revealed that cohabitation is often associated with poorer outcomes. Moving out of a cohabiting stepfamily into a single-mother family was not harmful and was actually associated with improvements in school engagement. Moving into a cohabiting stepfamily from a single-mother family decreased adolescent well-being, and this impact was greater than that experienced by those who moved into a married stepfamily. Stable cohabiting stepfamilies were associated with lower levels of well-being than stable married stepfamilies. Formalization of a cohabiting stepfamily through marriage did not translate into any appreciable benefits for adolescent well-being.

Co-occurring trajectories of delinquent behavior and depressive symptoms and their correlates were examined in a longitudinal sample of 985 middle-adolescent boys and girls (mean age = 15.54 years at Time 1). Dual trajectory analysis was used to identify the co-occurring trajectories. For boys (n = 472), 4 delinquency and 4 depression trajectory groups were found. For girls (n = 513), 3 delinquency and 3 depression trajectory groups were identified. The linkage between co-occurring trajectories was higher for girls than for boys. Stressful life events and childhood precursors of the outcomes predicted trajectory group membership for both genders fairly consistently. Findings suggest heterogeneity in developmental courses of delinquent behavior and depressive symptoms across adolescent boys and girls.

Previous reviews of the literature have suggested that shared environmental effects may be underestimated in adoption studies because adopted individuals are exposed to a restricted range of family environments. A sample of 409 adoptive and 208 non-adoptive families from the Sibling Interaction and Behavior Study (SIBS) was used to identify the environmental dimensions on which adoptive families show greatest restriction and to determine the effect of this restriction on estimates of the adoptive sibling correlation. Relative to non-adoptive families, adoptive families experienced a 41% reduction of variance in parent disinhibitory psychopathology and an 18% reduction of variance in socioeconomic status (SES). There was limited evidence for range restriction in exposure to bad peer models, parent depression, or family climate. However, restriction in range in parent disinhibitory psychopathology and family SES had no effect on adoptive-sibling correlations for delinquency, drug use, and IQ. These data support the use of adoption studies to obtain direct estimates of the importance of shared environmental effects on psychological development.

The search for genes of complex traits is aided by the availability of multiple quantitative phenotypes collected in geographically isolated populations. Here we provide rationale for a large-scale study of gene-environment interactions influencing brain and behavior and cardiovascular and metabolic health in adolescence, namely the Saguenay Youth Study (SYS). The SYS is a retrospective study of long-term consequences of prenatal exposure to maternal cigarette smoking (PEMCS) in which multiple quantitative phenotypes are acquired over five sessions (telephone interview, home, hospital, laboratory, and school). To facilitate the search for genes that modify an individual's response to an in utero environment (i.e. PEMCS), the study is family-based (adolescent sibships) and is carried out in a relatively geographically isolated population of the Saguenay Lac-Saint-Jean (SLSJ) region in Quebec, Canada. DNA is acquired in both biological parents and in adolescent siblings. A genome-wide scan will be carried out with sib-pair linkage analyses, and fine mapping of identified loci will be done with family-based association analyses. Adolescent sibships (12-18 years of age; two or more siblings per family) are recruited in high schools throughout the SLSJ region; only children of French-Canadian origin are included. Based on a telephone interview, potential participants are classified as exposed or nonexposed prenatally to maternal cigarette smoking; the two groups are matched for the level of maternal education and the attended school. A total of 500 adolescent participants in each group will be recruited and phenotyped. The following types of datasets are collected in all adolescent participants: (1) magnetic resonance images of brain, abdominal fat, and kidneys, (2) standardized and computer-based neuropsychological tests, (3) hospital-based cardiovascular, body-composition and metabolic assessments, and (4) questionnaire-derived measures (e.g. life habits such as eating and physical activity; drug, alcohol use and delinquency; psychiatric symptoms; personality; home and school environment; academic and vocational attitudes). Parents complete a medical questionnaire, home-environment questionnaire, a handedness questionnaire, and a questionnaire about their current alcohol and drug use, depression, anxiety, and current and past antisocial behavior. To date, we have fully phenotyped a total of 408 adolescent participants. Here we provide the description of the SYS and, using the initial sample, we present information on ascertainment, demographics of the exposed and nonexposed adolescents and their parents, and the initial MRI-based assessment of familiality in the brain size and the volumes of grey and white matter.

No self-report measure of attachment is well validated for middle-childhood. This study examined the validity and factor structure of the People in My Life (PIML) measure in 320 urban, fifth and sixth graders. Validity analyses consisted of correlational analyses between PIML subscales and the Child Behavior Checklist, Delinquency Rating Scale for Self and Others, Heath Resources Inventory, and Reynolds Child Depression Scale. Validity correlations were consistent with a-priori hypotheses. Confirmatory factor analyses consisted of comparison of model fit indices between seven models. Two models fit the data well and both models were consistent with the traditionally used PIML scoring protocol. Moreover, both models were consistent with the Inventory of Parent and Peer Attachment (IPPA), on which the PIML is modeled, as well as the theoretical underpinnings of attachment in childhood. The PIML and IPPA provide instruments for obtaining a continuous self-report measure of attachment from middle-childhood through adulthood.
