Titre : Adolescent attachment and trajectories of hostile–impulsive behavior: Implications for the development of personality disorders Type de document : Texte imprimé et/ou numérique Auteurs : Roger KOBAK, Auteur ; Kristyn ZAJAC, Auteur ; Clare SMITH, Auteur Année de publication : 2009 Article en page(s) : p.839-851 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Adolescents' trajectories of impulsive and hostile behaviors provide a dynamic index of risk for the emergence of Cluster B (antisocial and borderline) personality disorders in early adulthood. In the current study, we tested the hypothesis that preoccupied states of mind in the Adult Attachment Interview would increase both the level and rate of growth in adolescents' trajectories of aggressive and sexual risk-taking behaviors measured at ages 13, 15, and 17. Overall, preoccupied states of mind predicted higher levels of sexual risk taking and aggressive behaviors across all three assessments as well as higher rates of growth in sexual-risk taking and caregiver-reported aggression over time. In addition, preoccupied females showed slower rates of decline in self-reported hostile emotions than did preoccupied males. The effects of gender as a moderator of the relations between preoccupied status and risk trajectories for personality disorders are discussed.

Titre : Atypical dimensions of caregiver–adolescent interaction in an economically disadvantaged sample Type de document : Texte imprimé et/ou numérique Auteurs : Roger KOBAK, Auteur ; Kristyn ZAJAC, Auteur ; Caroline ABBOTT, Auteur ; Abby ZISK, Auteur ; Nadia BOUNOUA, Auteur Article en page(s) : p.405-416 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The Goal-Corrected Partnership Adolescent Coding System (GPACS) has shown promise in assessing a secure as well as three atypical patterns of parent–adolescent interaction during a conflict discussion. The current study of 186 economically disadvantaged families examines the degree to which four GPACS patterns: secure/collaborative, hostile/punitive, role confused, and disoriented, prospectively predict adolescents’ social competence and maladaptive behavior (internalizing, externalizing, and risk behaviors) at age 15 years after controlling for these social behaviors at age 13 years and contemporaneous GPACS scores. Adolescents from secure/collaborative dyads at age 13 were more likely to have a secure state of mind in the Adult Attachment Interview at age 15 and showed higher levels of teachers’ ratings of empathy and lower levels of teachers’ ratings of externalizing behaviors at age 15 years. Adolescents in disoriented dyads showed higher levels of teacher-rated internalizing problems, while male adolescents in role confused dyads reported higher levels of involvement in risk behaviors, including unprotected sexual activity and substance use problems.

Titre : Caregiver unresolved loss and abuse and child behavior problems: Intergenerational effects in a high-risk sample Type de document : Texte imprimé et/ou numérique Auteurs : Kristyn ZAJAC, Auteur ; Roger KOBAK, Auteur Année de publication : 2009 Article en page(s) : p.173-187 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This study examines the intergenerational effects of caregivers' unresolved loss and abuse on children's behavior problems from middle childhood to early adolescence in an economically disadvantaged sample. One hundred twenty-four caregivers completed the Adult Attachment Interbiew (AAI) and a lifetime trauma interview during the age 13 wave of the study. Child behavior problems were assessed at four time points (ages 6, 8, 10, and 13) with teacher-reported Child Behavior Checklist total problem scales. The children of insecure caregivers with unresolved loss showed a consistent pattern of increased behavior problems from middle childhood to early adolescence. Caregivers' AAI status accounted for more variance in child behavior problems than did an alternative model of caregiver psychopathology (depression and dissociation). The results extend the literature on the effects of caregiver unresolved states of mind beyond infancy to older children and adolescents.

Titre : Cortisol and antisocial behavior in early adolescence: The role of gender in an economically disadvantaged sample Type de document : Texte imprimé et/ou numérique Auteurs : Roger KOBAK, Auteur ; Seymour LEVINE, Auteur ; Kristyn ZAJAC, Auteur Année de publication : 2009 Article en page(s) : p.579-591 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This study examines the relation between adolescents' antisocial behaviors and adrenocortical activity during a laboratory visit in a sample of economically disadvantaged families (N = 116, ages 12–14, 51% female). Pretask cortisol levels indexed adolescents' prechallenge response to the lab visit, whereas adolescents' response to a conflict discussion with their caregivers was indexed with residualized change in pre- to postconflict cortisol levels. A trait measure of antisocial behavior (derived from parent, teacher, and self-reports) was associated with lower pretask cortisol levels but greater cortisol response to the conflict discussion. Gender moderated antisocial adolescents' cortisol response to the conflict discussion with girls who reported more covert risky problem behaviors showing an increased cortisol response. The findings suggest that, although antisocial adolescents had lower pretask cortisol levels, conflict discussions with caregivers present a unique challenge to antisocial girls compared with antisocial boys.

KILPATRICK, Auteur Année de publication : 2011 Article en page(s) : p.136-143 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Epidemiological studies have identified recent declines in specific types of adolescent substance use. The current study examined whether these declines varied among youth with and without a history of interpersonal victimization or posttraumatic stress disorder (PTSD). Data for this study come from two distinct samples of youth (12-17 years of age) participating in the 1995 National Survey of Adolescents (N = 3,906) and the 2005 National Survey of Adolescents-Replication (N = 3,423). Results revealed significant declines in adolescents' use of cigarettes and alcohol between 1995 and 2005; use of marijuana and hard drugs remained stable. Of importance, declines in nonexperimental cigarette use were significantly greater among youth without versus with a history of victimization and declines in alcohol use were significantly greater among youth without versus with a history of PTSD.
