Is There a Place for Cognitive Restructuring in Brief, Self-Guided Interventions? Randomized Controlled Trial of a Single-Session, Digital Program for Adolescents.

ABSTRACT

OBJECTIVE: Self-guided digital mental health interventions (DMHIs) teaching empirically supported skills (e.g. behavioral activation) have demonstrated efficacy for improving youth mental health, but we lack evidence for the complex skill of cognitive restructuring (CR). METHOD: We conducted the first-ever RCT testing a CR DMHI ("Project Think") against an active control (supportive therapy; "Project Share") in collaboration with public schools. Pre-registered outcomes were DMHI acceptability and helpfulness post-intervention, as well as internalizing symptoms and CR skills use from baseline to seven-month follow-up, in the full sample and the subsample with elevated symptoms. RESULTS: Participants (N = 597; MAge = 11.99; 48% female; 68% White) rated both programs highly on acceptability and helpfulness. Both conditions were associated with significant internalizing symptom reductions across time in both samples, with no significant condition differences. CR skills use declined significantly across time for Project Share youths but held steady across time for Project Think youths in both samples; this pattern produced a significant condition difference favoring Project Think within the elevated sample at seven-month follow-up. CONCLUSION: Internalizing symptoms declined comparably for Think and Share participants. Consequently, future research should examine whether encouraging youths to share their feelings produces symptom improvements, and whether a single-session, self-guided CR DMHI produces beneficial effects relative to more inert control conditions. Further, the decline in CR skills use for Project Share youths versus sustained CR use by Project Think youths raises questions about the natural time course of youths' CR use and the impact of these DMHIs on that course.
