Aim: The aim of this study is to explore the use of the Questionnaire Appraisal System with a combination of qualitative and quantitative methods in cognitive interviewing for cross-cultural adaptation.
Design: This is a descriptive methodological study.
Methods: Using the Mandarin version of the Post-Stroke Checklist as an example, cognitive interviews were conducted with 27 stroke survivors in Guangzhou between November 2020 and February 2021. The Questionnaire Appraisal System was applied as a codebook in focus group discussions to perform quantitative data collections and quantitative content analysis.
Results: Thirty-eight problems were proposed in focus group discussions and identified all but four of the 30 questions that emerged in the cognitive interviews. A new item was added to the Questionnaire Appraisal System for better categorization. Four categories and six subcategories of problems in the checklist were revealed.
Keywords: cognitive interviewing; cross-cultural adaptation; focus groups; methodological studies; nursing.
