Table 1 Process evaluation procedures mapped to measures, outcomes and Behaviour Change Techniques
Component | Question | Method/Measure | Data Type | Outcomes | aBehaviour Change Techniques (Intervention Function) | |
|---|---|---|---|---|---|---|
1. | Program Adherence (Fidelity) | How well did the O&M Specialists deliver the v-LiFE program to participants? | • A trained observer will observe 1–2 participant sessions with each instructor using a checklist, while making comments (20% of all v-LiFE program participants). | Quantitative | Higher scores indicate well delivered v-LiFE programs | Feedback on behaviour (Education/Persuasion/Coercion); Credible source (Persuasion); Instruction on how to perform the behaviour (Training); Problem solving (Enablement) |
Qualitative | Analysis of observer’s comments using the BCW as a framework | |||||
2. | Complete Delivery (Dose delivered) | To what extent were all of the intended components of the v-LiFE program delivered to participants? | • O&M Specialists to record each time they complete a session, booster session, additional sessions and/or phone calls. | Quantitative | Higher scores indicate participants received a higher program dose | Self-monitoring of behaviour (Education/Incentivisation); Monitoring of behaviour by others without evidence of feedback (Coercion); Prompt/cues (Education) |
3. | Participant Receipt (Dose received) | To what extent were participants engaged/satisfied with the v-LiFE program? | • Semi-structured interview (30 participants). | Qualitative | Analysis of transcripts using the BCW as a framework | Information about health consequences, self-monitoring of behaviour (Education); Monitoring of behaviour by others without evidence of feedback (Coercion) |
• Short answer survey (all participants). | Quantitative | Higher scores on the AFRIS indicate higher engagement to v-LiFE | ||||
4. | Participant Enactment | To what extent were the participants completing the prescribed activities? | • The Self-Report Habit Index (post-program) | Quantitative | Higher scores on the Index indicate stronger habit formation | Self-monitoring of behaviour (Education/Incentivisation/Coercion); Feedback on behaviour (Education/Incentivisation/Coercion); Monitoring of outcome of behaviour by others without evidence of feedback (Incentivisation/Coercion |
