A Developmental Cascade Analysis of Peer Rejection, Depression, Anxiety, and Externalizing Problems from Childhood through Young Adulthood.

The need to belong with peers is an essential component of development, and when individuals face peer rejection they often experience a host of negative outcomes, including internalizing and externalizing problems. There exists conflicting evidence whether peer rejection precedes, succeeds, or reciprocally influences psychopathology.

Anxiety and Depression from Childhood to Young Adulthood: Trajectories and Risk Factors.

This study aimed to (1) evaluate how population levels of anxiety and depression grow and correlate from middle childhood through early adulthood, and (2) determine whether sex, family socioeconomic status, parental education, academic achievement, learning disabilities, or externalizing symptoms predict anxiety and/or depression levels and growth trajectory. We used two longitudinal samples (N = 445, 448) of Portuguese children. Mean depression levels increased from mid-childhood through adolescence before stabilizing in early adulthood and were most strongly predicted by academic achievement and learning disabilities.

Testing Syndromes of Psychopathology in Parent and Youth Ratings Across Societies.

As societies become increasingly diverse, mental health professionals need instruments for assessing emotional, behavioral, and social problems in terms of constructs that are supported within and across societies. Building on decades of research findings, multisample alignment confirmatory factor analyses tested an empirically based 8-syndrome model on parent ratings across 30 societies and youth self-ratings across 19 societies. The Child Behavior Checklist for Ages 6-18 and Youth Self-Report for Ages 11-18 were used to measure syndromes descriptively designated as , and .
