|---|---|---|
Outcome | Outcome measure(s) | Methods of analysis |
Acceptability: a willingness to receive the offered intervention | - Enrollment rate (%) - Attrition/retention rate (%) - Engagement rate (% at least 1 home visit and 1 group session) - Dose of the intervention (number of visits and/or group sessions attended) | - Compare observed rates to targets set for study - Characteristics of consenters versus nonconsenters - Descriptive statistics for total dose, number of visits, number of group sessions |
Appropriateness: from the perspective of interventionists | - Perceived benefit to participants - Convenience of implementation | Qualitative descriptive analysis of focus group and outreach meetings |
Adoption: the intervention is appealing to providers and realistic to implement in practice | - Enrollment rate (%) - Attrition/retention rate (%) - Engagement rate (% at least 1 home visit and 1 group session) - Dose of the intervention (number of visits and/or group sessions attended) | - Compare observed rates to targets set for study - Characteristics of consenters versus nonconsenters - Descriptive statistics for total dose, number of visits, number of group sessions |
Feasibility: the capability to carry out intervention activities | - Training of the interventionists - Delivery of the program - Perceptions of barriers and facilitators | - Evaluation of training materials, log sheets - Qualitative descriptive method to analyze focus group content |
Fidelity: adherence to intervention components | Refer to Fidelity Checklist (Additional file 3) | - Review records of attendance at training session and monthly meetings with researchers - Review home visit records and log sheets to assess delivery of the program as planned |
Reach: degree to which the target population is eligible to receive the intervention (coverage) | - Proportion of clients eligible - Reasons for exclusion - Characteristics of eligible clients | - Descriptive statistics |
Maintenance: the extent to which the intervention can be sustained | - Engagement rate (%) - Attrition /retention (%) - Reported reasons for attrition - Prospects for the program’s uptake in practice setting | - Descriptive statistics - Qualitative descriptive method to analyze focus group content |
Cost: from a societal perspective | - Health and Social Services Utilization Inventory (HSSUI) [90] | - Comparison of baseline (T 1) and 6-month (T 2) median costs using Mann-Whitney U test |
