Exploring barriers and facilitators for mental health professionals delivering behavioural activation to young people with depression: qualitative study using the Theoretical Domains Framework.

Background: Depression prevalence among young people is increasing, with growing pressures on specialist mental health services. Manualised behavioural activation therapy may be effective for young people, and can be delivered by a range of mental health professionals (MHPs). This study explored clinician perspectives of barriers and facilitators to implementing behavioural activation with young people in routine practice.

Aims: We conducted a qualitative study with individual semi-structured interviews with MHPs, as part of a wider feasibility study.

Method: Participants were mental health professionals (therapists and supervisors) from two UK NHS sites delivering manualised behavioural activation for young people. Data were analysed with an inductive followed by deductive approach, applying the Theoretical Domains Framework (TDF) to understand key influences on practice change. Identified domains were mapped onto possible behaviour change techniques (BCTs) to support implementation, using the Theory and Techniques Tool (TTT).

Results: Nine MHPs were interviewed. Thirteen of fourteen TDF domains were relevant, including perceived professional identity, beliefs about own capabilities and perceived positive or negative consequences of using manualised behavioural activation, social influences, memory and attention, and environmental resources. Fourteen theory-linked BCTs were identified as possible strategies to help clinicians overcome barriers (e.g. integrating behavioural practice/rehearsal, prompts and persuasive communications within training, and supervision).

Conclusions: Behavioural science approaches (TDF, TTT) helped conceptualise key barriers and facilitators for MHPs delivering manualised behavioural activation with young people. Interventions using BCTs to address identified barriers could help the implementation of new therapies into routine practice, working to bridge the research-practice gap in clinical psychology.
