Table 6 Feasibility of research methods and cut-off points
Preliminary cut-off points to validate the feasibility of research methods | Threshold | Observed values | Cut-off point reached? |
|---|---|---|---|
Recruitment of the target number of participants (n = 20) within 4 months of study initiation (= 122 days) | 122 days | 134 days | No |
Attendance of intervention participants in follow-up sessions (home visits) | ≥ 80% | 90.0% | Yes |
Attrition rate | ≤ 15% | 10.0% | Yes |
Rate of complete data sets | ≥ 80% | 85.0%a | Yes |
Rate of treatment contamination | ≤ 15% | 0.0% | Yes |
Rate of participants having perceived no or low burden of study participation | ≥ 90% | 88.2% | No |
