This article presents results from a 3-year longitudinal study of the growth patterns and correlates of perceived discrimination by adults and by peers among Black, Latino, and Asian American high school students. Results revealed a linear increase over time in levels of perceived discrimination by adults, whereas perceptions of discrimination by peers remained stable over time. Asian American and non-Puerto Rican Latino adolescents (primarily Dominican) reported higher levels of peer and/or adult discrimination than did Puerto Rican youth, whereas Black adolescents reported a steeper increase over time in levels of perceived discrimination by peers and by adults than did Puerto Rican adolescents. Peer and adult discrimination was significantly associated with decreased self-esteem and increased depressive symptoms over time. Ethnic identity and ethnicity were found to moderate the relationships between perceived discrimination and changes in psychological well-being over time. Results underscore the need to include perceptions of discrimination when studying the development and well-being of ethnic minority adolescents.

The current study modeled developmental trajectories of ethnic identity exploration and affirmation and belonging from middle to late adolescence (ages 15-18) and examined how these trajectories varied according to ethnicity, gender, immigrant status, and perceived level of discrimination. The sample consisted of 135 urban low-income Black and Latino adolescents (42% male, 34% Black, 66% Latino). Consistent with developmental theory, individual growth modeling identified an average quadratic trajectory of ethnic identity exploration characterized by decelerating levels of exploration after 10th grade. However, ethnicity and perceived discrimination by peers moderated this pattern. No uniform growth pattern in affirmation was found and Black and Latino adolescents displayed equally high levels of affirmation over time.

Purpose: To determine the association of frequency of illegal drug use with five groups of factors: environmental stressors; parental drug use; parental child rearing; peer drug use; and adolescent personal attributes.Methods: 1468 male (45%) and female (55%) adolescents, aged 12 to 17 years (mean=14.76, S.D.=1.51), were interviewed at home in Durban and Capetown, South Africa. Independent measures assessed environmental stressors, parental child rearing, parental drug use, peer drug use, and adolescent personal attributes. The dependent variable was the adolescents' frequency of illegal drug use.Results: Regression analyses showed that personal attributes and peer substance use explained the largest percentage of the variance in the adolescents' frequency of illegal drug use. In addition, both parental factors and environmental stressors contributed to the explained variance in adolescent drug use above and beyond the two more proximal domains at a statistically significant level. Conclusions:Knowing the contribution of more proximal versus more distal risk factors for illegal drug use is useful for prioritizing targets for interventions. Targeting changes in the more proximal predictors (e.g., adolescent personal attributes) may be more effective as well as more feasible than trying to produce change in the more distal factors such as environmental stressors.
