The prevalence of most adult psychiatric disorders varies across racial/ethnic groups and has important implications for prevention and intervention efforts. Research on racial/ethnic differences in the prevalence of internalizing and externalizing symptoms and disorders in adolescents has been less consistent or generally lacking. The current study examined the prevalence of these symptom groups in a large sample of sixth, seventh, and eighth graders in which the three major racial/ethnic groups in the U.S. (White, Black, and Hispanic/Latino) were well-represented. Hispanic females reported experiencing higher levels of depression, anxiety, and reputational aggression than other groups. Black males reported the highest levels of overtly aggressive behavior and also reported higher levels of physiologic anxiety and disordered eating than males from other racial/ethnic groups. Hispanic females also exhibited higher levels of comorbidity than other racial/ethnic groups.
KeywordsRacial/ethnic differences; Adolescence; Anxiety; Depression; Eating pathology; Aggression Racial/ethnic differences in the prevalence of symptoms of depression (Blazer et al. 1994;Kessler et al. 1994), anxiety (Brown et al. 1990), and eating disorders (Striegel-Moore et al. 2003) have been documented in a number of studies utilizing adult samples. There has been substantially less work examining racial/ethnic differences in the prevalence of psychopathology in adolescents. Large epidemiologic studies of adolescent psychopathology have typically not focused on racial/ethnic group differences in symptoms or have not included substantial numbers of ethnic minorities. For example, in the Oregon Adolescent Depression Project (Lewinsohn et al. 1993) over 90% of participants were White. Similarly, in the Dunedin Multidisciplinary Health and Development Study the vast majority of participants were White (e.g., McGee et al. 1990). Understanding racial/ethnic differences in psychopathology is important for the identification of at-risk groups and targets for prevention efforts, improvement of mental health services, and as a first step in understanding the mechanisms by which risk factors confer vulnerability to psychopathology differentially on various segments of the population.The research that has been conducted examining race/ethnicity differences in adolescent psychopathology has yielded inconsistent findings about differences in the prevalence of symptoms of depression, anxiety, eating disorders, and aggression. Some studies document significant group differences (e.g., Roberts and Chen 1995;Austin and Chorpita 2004) while others have reported no differences in symptoms across groups (e.g., Cole et al. 1998).Correspondence to: Katie A. McLaughlin, katie.mclaughlin@yale.edu. Another explanation for disparate findings in studies comparing rates of symptoms in different racial/ethnic groups involves the inclusion of children and adolescents from different age groups (e.g., Kistner et al. 2003;Ollendick et al. 1996).
