Cross-cultural adaptation and cognitive interview-based content validation of the English Participation Behaviour Questionnaire (PBQ), to measure participation in individuals with hand injuries

The English-adapted PBQ demonstrated evidence of content validity based on participant feedback regarding clarity, relevance, and comprehensibility. The 18 substantive revisions enhanced cultural and linguistic appropriateness by addressing clarity in 22 of 37 items, refining ambiguous terminology, and incorporating Canadian-contextual examples where necessary. These findings represent an initial step in the overall validation process; in this pre-psychometric, single-center Canadian-English study, additional research is required to assess the instrument's psychometric properties, including construct validity, reliability, and responsiveness.
