Approximately half of the adolescents' parents opted to complete a parent assessment, including the SITBI-R, on behalf of their child. Inter-rater reliability, convergent validity, and inter-informant agreement were assessed.<h4>Results</h4>The SITBI-R exhibited overall excellent inter-rater reliability and good convergent validity in adolescents. Parent-adolescent agreement ranged from fair to poor across most outcomes, with parents tending not to report past self-injurious thoughts and behaviors endorsed by their children.<h4>Conclusions</h4>The present study suggests that the SITBI-R can be extended for use with adolescents. Future research should evaluate moderators and implications of parent-adolescent disagreement, particularly with regard to suicide risk.Journal of clinical child and adolescent psychology : the official journal for the Society of Clinical Child and Adolescent Psychology, American Psychological Association, Division 53Self-Injurious Thoughts and Behaviors Interview-Revised (SITBI-R): Reliability, Validity, and Inter-Informant Agreement in an Adolescent Sample.PMC8577009R15 MH113076R15 MH113076-01A1Fernandes SNPollak OHCha CBBell KAEbo TGratch IFox KRTezanos KfalseSelf-Injurious Thoughts and Behaviors Interview-Revised (SITBI-R): Reliability, Validity, and Inter-Informant Agreement in an Adolescent Sample.<h4>Objective</h4>The present study sought to evaluate the psychometric properties and inter-informant agreement of the <i>Self-Injurious Thoughts and Behaviors Interview-Revised</i> (<i>SITBI-R</i>) in adolescents and their parents.<h4>Method</h4>Suicidal and nonsuicidal adolescents from the community (<i>N</i> = 206), ages 12-19 years, were administered the SITBI-R during a lab visit.
