An online, single-session intervention for adolescent self-injurious thoughts and behaviors: Results from a randomized trial.

Abstract

BACKGROUND\nAcross 50 years of research, existing interventions for self-injurious thoughts and behaviors (SITBs) in adolescents have remained largely ineffective and inaccessible. Single-session interventions, interventions designed to last one session, may be a low-cost and timely resource for adolescents engaging in SITBs who may not otherwise receive treatment.\n\n\nMETHOD\n565 adolescents (Mage\xa0=\xa014.95 years) endorsing recent engagement in non-suicidal self-injury (NSSI) were randomized to receive a 30-min, web-based, single-session intervention- Project SAVE -or an active, attention-matched control program. Proximal outcomes were measured at baseline and immediately post-intervention. Long-term outcomes were measured at baseline and 3-month follow-up.\n\n\nRESULTS\nAdolescents rated Project SAVE as acceptable; 80% of participants randomized to SAVE completed the intervention. Between-group effects were non-significant for pre-registered outcomes: post-intervention likelihood of future NSSI; 3-month frequencies of NSSI and suicidal ideation at follow-up. Relative to control-group participants, SAVE participants reported short-term improvements in two exploratory outcomes: self-hatred (d\xa0=\xa0-.35, p<.001) and desire to stop future NSSI (d = .25, p = .003).\n\n\nCONCLUSIONS\nProject SAVE is an acceptable resource for adolescents engaging in SITBs-with short-term effects on clinically-relevant outcomes. Future research may evaluate SAVE as an easy-to-access, short-term coping resource for youth engaging in SITBs. CLINICAL TRIALS.\n\n\nGOV IDENTIFIER\nNCT04498143.
