Patterns of correlates, comorbidity and impairment associated with attention-deficit hyperactivity disorder (ADHD) in children and youth were examined in representative samples from the community and from treatment facilities serving medically indigent youth in Puerto Rico. Information from caretakers and youths was obtained using the Diagnostic Interview Schedule for Children, (version IV), measures of global impairment, and a battery of potential correlates. In the community (N = 1,896) and the treated samples (N = 763), 7.5 and 26.2% of the children, respectively, met criteria for DSM-IV ADHD in the previous year. Although the prevalence rates and degree of impairment differed, the general patterns of correlates, comorbidity and impairment were similar in both populations. The exceptions were associated with conduct disorder, anxiety, impairment in the ADHD comorbid group, and age factors that appeared to be related to selection into treatment. [ABSTRACT FROM AUTHOR]

Latino children in the U.S. have high rates of unmet need for mental health services, perhaps due to biased perceptions of impairment and need for care by parents and providers. We tested this argument using an experimental vignette design. Vignettes described children with problems that varied on severity (mild vs. serious), nature of the problem (internalizing vs. externalizing), as well as gender and ethnicity (Latino vs. Anglo). Raters were Latino and Anglo parents ( N = 185) and providers ( N = 189). Vignettes with Latino names were viewed as more impaired by both parents and providers, and this effect was significantly stronger in Latino vignettes with less severe problems. Severity and Latino features of vignettes also interacted with judgments of need for service. At higher severity, vignettes with Anglo names were judged to need service more than vignettes with Latino names, despite the same judged levels of impairment. Results are discussed in the light of the unmet need for Latinos. [ABSTRACT FROM AUTHOR]
