Substance use patterns and mental health comorbidities in youth with a history of depression or suicidality: Findings from TX-YDSRN.

Using a brief, self-report measure of substance use, we identified three classes of substance users differing in probability of past-year use, which were predicted by older age and some psychiatric comorbidities. While research on universal screening of substance use in youth remains limited, we discuss who may benefit from such screening among depressed youth.
