Table 1 PBA implementation in PROACTIVE
Stage of intervention development and evaluation | Specific PBA activities useful at each stage | PROACTIVE planning, development and optimisation | Additional activities |
|---|---|---|---|
1. Intervention planning | • Synthesise previous qualitative studies of user experiences of similar interventions • Carry out qualitative research to elicit user views of the planned behaviour changes and intervention (including relevant previous experience, barriers and facilitators) | • Review of existing interventions in the field • Qualitative study | • A systematic review and meta-analysis of depression and anxiety in prostate cancer (evidence-based approach activity) |
2. Intervention design | • Use themes arising from the intervention planning stage to identify key issues, needs and challenges the intervention must address • Create guiding principles, comprising (a) key intervention design objectives and (b) key distinctive features of the intervention needed to achieve objectives | • Use themes from qualitative study to identify key issues, needs and challenges Proactive must address • Create guiding principles |  |
3. Intervention optimisation and evaluation of acceptability and feasibility | • Elicit and observe user reactions to every intervention element (e.g. using thinkÂaloud techniques), iteratively modifying intervention to optimise acceptability and feasibility • Carry out detailed longitudinal mixed methods case studies of independent intervention usage | • Create Proactive prototype, conduct think aloud interviews and modify the intervention accordingly |  |
