Helpful for all? Examining the effects of psychotherapy treatment history on outcomes of single session, transdiagnostic cognitive behavioral interventions for university students.

Brief, transdiagnostic interventions are an efficient form of mental health care for resource-limited settings like universities. Little research, however, has examined for whom these treatments are most effective. One important factor may be psychotherapy treatment history. Here, we evaluate if treatment history influences the effects of a single-session cognitive behavioral group intervention with optional digital follow-up support across two independent, university-based studies. Undergraduate ( N = 143) and graduate ( N = 51) students reported their psychotherapy treatment history and completed self-report measures of emotional health before and approximately 1-month following the intervention. Across both samples, psychotherapy treatment history did not moderate changes in depression, anxiety, or emotional avoidance following the intervention. However, participants who were currently receiving psychotherapy began the workshop with lower coping self-efficacy than peers with no prior psychotherapy and saw larger gains in coping self-efficacy at follow-up. Results suggest that regardless of whether a student has previously received psychotherapy, they may benefit from brief, group transdiagnostic interventions.
