Few longitudinal studies examine how "changes" in parent-child relationships are associated with changes in youth internalizing problems. In this longitudinal study, we investigated how developmental trends (linear change) and year-to-year lability (within-person fluctuations) in parental warmth and hostility across Grades 6 to 8 predict…

Background: Adolescents face major developmental tasks such as increasing individuation and establishing autonomy. These developmental tasks increase demands on adolescent self-control, hereby putting youth with poor effortful control at risk for psychopathology. Specific parenting behaviors might be warranted to buffer against this risk.…

This study examined pubertal maturation, pubertal timing and outcomes, and the relationship of puberty and sexual identity developmental milestones among 507 lesbian, gay, and bisexual youth. The onset of menarche and spermarche occurred at the mean ages of 12.05 and 12.46, respectively. There was no statistically significant difference in…

Patterns of nonsuicidal self-injury (NSSI) and their association with other psychological difficulties were studied in a community sample of young Swedish adolescents, by a two-wave longitudinal design with a 1-year interval. Hierarchical cluster analysis at T1 identified eight NSSI subgroups in each gender, of which five were clearly replicated…

Individuals with autistic traits are considered to be prone to develop psychosexual problems due to their limited social skills and insight. This study investigated the longitudinal relation between autistic traits in childhood (T1; age 10-12 years) and parent-reported psychosexual problems in early adolescence (T2; age 12-15 years). In a general…

This study examined the associations between sibling intimacy and conflict and youths' reports of risky behavior in a sample of adolescents ages 11-20. Participants were mothers, fathers, and sibling dyads in 393 families who were interviewed annually for 3, 4, or 5 years. Multivariate multilevel models tested longitudinal links between sibling…

The current study used developmental trajectories to examine the relationship between internalising and externalising behaviours and victimisation over the transition period from primary to secondary school. Data were collected using a self-completion questionnaire four times over 3 years from 3,459 students aged 11-14 years. Students were tracked…

The literature consistently shows an association between pubertal maturation and internalizing problems in girls. The association for boys is less clear. The present study examines genetic and environmental influences on the association between pubertal maturation and internalizing problems for boys and girls in two primarily Caucasian adolescent…

Objective: This study investigated the long-term effects of exposure to intimate partner violence in the home on adolescent violence and drug use and gender differences in these relationships. Although the general relationship between exposure to IPV and negative outcomes for youth has been demonstrated in past research, gender differences in the…

The transition period from primary to secondary school is a critical time in adolescent development. The high prevalence of adolescent mental health problems makes understanding the causal pathways between peer victimisation and internalising symptoms an important priority during this time. This article utilises data collected from self-completion…

This study extends previous research investigating the developmental pathways predicting adolescent alcohol and marijuana use by examining the cascading effects of externalizing and internalizing symptoms and academic competence in the prediction of use and level of use of these substances in adolescence. Participants (N = 191) were drawn from a…

Bullying and victimization occurring in adolescence can have a long-lasting negative impact into adulthood. This study investigates whether conduct problems (CP) and dimensions of psychopathy predict the developmental course of bullying and victimization from ages 12 to 14 among 1,416 Greek-Cypriot adolescents. Results indicate that initial levels…

Objective: Based on the data obtained through Child Protective Services (CPS) case records abstraction, this study aimed to explore patterns of overlapping types of child maltreatment in a sample of urban, ethnically diverse male and female youth (n= 303) identified as maltreated by a large public child welfare agency. Methods: A cluster analysis…

The present study examines the quality of peer relations as a mediator between exposure to IPV (intimate partner violence) and internalizing behaviors in a sample of 129 preadolescents and adolescents (ages 10-18), who were interviewed via telephone as part of a multigenerational, prospective, longitudinal study. Relational victimization is also…

The purpose of this study was to investigate the trajectories of behavioral problems for a sample of predominately minority adolescents (n = 212, 91% African-American and/or Hispanic, 45% boys, 55% girls) in a large, urban school district and to determine the impact of parental and peer relationships, gender, and risk status on their development…
