Development of a Questionnaire on the Use of Outcome Measures by Korean Physical Therapists Using Focus Group Interview-Based Cognitive Interviewing

ABSTRACT

Purpose@#This study developed a Korean sentiment questionnaire by adapting an existing English survey using focus group interview (FGI)-based cognitive interview (CI) techniques to investigate the utilization of outcome measures (OMs) among Korean physical therapists. @*Methods@#The existing OMs survey questionnaire was adapted by dividing eight physical therapists into two groups: mid-experienced (n=4) and high-experienced (n=4). Each group participated in a 120-minute FGI-based CI session. All interviews were recorded, and the researcher transcribed the data immediately after each interview. The data were then organized and categorized into themes using Excel 2021 and verified with the participants. @*Results@#FGI-based CI sessions were conducted with Korean physical therapists to revise the English version of the questionnaire, tailoring it to the local context. Four main themes emerged from the interviews: inappropriate items or translations, questionnaire length and organization, questionnaire improvements, and additional items. The questionnaire was revised based on the feedback obtained during these interviews. @*Conclusion@#The questionnaire was modified according to the themes derived from the interviews. The questionnaire was developed to represent the clinical environment of Korean physical therapy accurately by removing elements of the questionnaire unsuitable for the Korean sentiment and incorporating the perspectives of Korean physical therapists.
