Obsessive-compulsive disorder (OCD) is a chronic psychiatric disorder that causes significant impairment. However, treatment for OCD isn’t widely accessible and ineffective for some patients. To this end, we developed a mobile-based training to modify an underlying cognitive bias of OCD and ensure accessibility. This study examines the feasibility and acceptability of Cognitive Bias Modification –Thought Action Fusion in an undergraduate sample. In a randomized controlled trial (RCT), 36 participants with moderate OCD symptoms were randomized into one of three groups: CBM-TAF (active), Stress Management Psychoeducation (SMP; control), and waitlist (WL; control). SMP is a comparable intervention to CBM-TAF in reducing emotional distress without modifying TAF. Participants in CBM-TAF or SMP completed up to six cognitive training sessions (2x/week for three weeks). WL participants completed three weekly assessments. Afte0r the third week, participants completed a Treatment Acceptability Questionnaire (TAQ). This presentation analyzed indices related to the acceptability and feasibility of this mobile-based intervention. The retention rate was 87% in CBM-TAF and 82% in SMP. The average sessions completed were 5.19 in CBM-TAF and 5.38 in SMP. The total acceptability score was 34.31 in CBM-TAF and 34.50 in SMP, with no significant difference (p = 0.930). Independent samples t-tests showed no significant differences between CBM-TAF and SMP in training acceptability, ethics, perceived effectiveness, side effects, or staff trustworthiness (p = 0.17 – 0.52). However, CBM-TAF rated staff knowledgeability higher than SMP, t(21) = 2.79, p = 0.011. The results indicate that mobile-based OCD training is feasible and acceptable for undergraduate students, with a high retention rate of 82-86%. Both training groups were comparable in acceptability, ethics, effectiveness, side effects, and staff trustworthiness. Compared to the well-established stress management intervention, CBM-TAF showed similar acceptability and feasibility as a new mobile-based intervention. The high session completion rate in both groups indicates strong participant engagement.
