Psychiatry and Primary Care11Recent epidemiologic studies have found that most patients with mental illness are seen exclusively in primary care medicine. These patients often present with medically unexplained somatic symptoms and utilize at least twice as many health care visits as controls. There has been an exponential growth in studies in this interface between primary care and psychiatry in the last 10 years. This special section, edited by Jürgen Unutzer, M.D., will publish informative research articles that address primary care-psychiatric issues.

Determinants of mental health service use among depressed adolescents

Evaluate determinants of mental health service use among depressed adolescents.We assessed mental health services use over the 12 months following screening among 113 adolescents (34 males, 79 females) from an integrated healthcare system who screened positive for depression (Patient Health Questionnaire-9 score ≥11). Youth characteristics (demographics, depression severity, and co-morbidity) and parent characteristics (parent history of depression, parent-report of youth externalizing and internalizing problems) were compared among youth who had received mental health services and those who had not. Multivariate regression was used to evaluate the strongest factors associated with mental health service use.Overall, 52% of adolescents who screened positive for depression received mental health service in the year following screening. Higher parent-reported youth internalizing problems (OR 5.37, CI 1.77–16.35), parental history of depression/anxiety (OR 4.12, CI 1.36–12.48) were significant factors associated with mental health service use. Suicidality and functional impairment were not associated with increased mental health services use.Parental factors including recognition of the adolescent's internalizing symptoms and parental experience with depression/anxiety are strongly associated with mental health service use for depressed adolescents. This highlights the importance of educating parents about depression and developing systems to actively screen and engage youth in treatment for depression.
