Although crucial for symptom improvement, task completion remains a challenge, and research on predictors of BSW engagement in low-intensity contexts is limited. This qualitative study employed interpretive description methodology and framework analysis to interview 24 patients from UK NHS Talking Therapies services, exploring barriers and facilitators to between-session engagement in low-intensity CBT-based interventions. Themes constructed emphasised the importance of prioritising BSW, where between-session activities are endorsed during sessions to cultivate favourable patient attitudes. Specific, tailored task planning, continuous practitioner review and proactive responses to non-completion were key to secure engagement. External support from patients' social networks also reinforced engagement and mitigated barriers such as time constraints.
