Description:

This Master Prompt would focus on establishing whether the proposed questionnaire adequately represents the construct and content domain it is intended to measure. It would guide researchers through expert review, content-validity assessment, Delphi procedures, stakeholder consultation, target-population involvement, relevance assessment, comprehensiveness assessment, comprehensibility assessment, item-objective congruence, and systematic revision of the initial item pool.

A major emphasis would be placed on treating content validity as an evidence-based development process rather than simply asking several experts whether the questionnaire looks acceptable. Researchers would document expert selection, evaluation criteria, disagreements, item modification, item deletion, and the rationale for retaining important content. The uploaded studies demonstrate multistage development involving Delphi surveys, focus groups, consultations and target-user participation, with relevance, comprehensibility, and comprehensiveness explicitly evaluated. Another study used five experts and item-objective congruence to eliminate unsuitable questionnaire items before subsequent reliability testing.
