Stage | Description | Minimum participants (approx.) | Contributes to final data? |
|---|---|---|---|
Review items | Review CPAS candidate items with local collaborators and academic peers for completeness and relevance in local setting, add candidate items suggested by collaborators, and adjust existing items as needed | Not applicable | Not applicable |
Pretest | Pretest candidate CPAS items with a sample of participants from the underlying population of interest using cognitive interviewing | 25 | No |
Shorten the instrument | Pilot items with participants and use first 100 administrations for basic psychometric analyses, remove any poorly performing items | 30–50 | Yes |
Assess validity | Administer questionnaire to participants and use first ~250 administrations to generate data to assess validity, including retest reliability if feasible; eliminate items to refine final subscales as appropriate based on EFA | 250 | Yes |
