This experimental study examined the effect of communication about type of screening follow-up (in-person follow-up vs. no in-person follow-up) on adolescents' responses to a self-report suicide risk screen. Participants were 245 adolescents (131 girls, 114 boys; ages 13-17; 80% White, 21.6% Black, 9.8% American Indian, 2.9% Asian) seeking medical emergency services. They were randomized to a screening follow-up condition. Screening measures assessed primary risk factors for suicidal behavior, including suicidal thoughts, depressive symptoms, alcohol use, and aggressive/delinquent behavior. There was no main effect of follow-up condition on adolescents' screening scores; however, significant interactions between follow-up condition and public assistance status were evident. Adolescents whose families received public assistance were less likely to report aggressive-delinquent behavior if assigned to in-person follow-up. Adolescents whose families did not receive public assistance reported significantly higher levels of suicidal ideation if assigned to in-person follow-up. Findings suggest that response biases impact some adolescents' responses to suicide risk screenings. Because national policy strongly recommends suicide risk screening in emergency settings, and because screening scores are used to make critical decisions regarding risk management and treatment recommendations, findings indicate the importance of improving the reliability and validity of suicide risk screening for adolescents.
