Validation and Reliability of the Vietnamese Pain Self-Efficacy Questionnaire in Knee Osteoarthritis

This study aims to evaluate the reliability and convergent validity of the Vietnamese version of the Pain Self-Efficacy Questionnaire (VIET-PSEQ) in patients with knee osteoarthritis (KOA). Pain self-efficacy refers to a person's confidence in managing their pain and maintaining daily activities despite it. A total of 173 patients with KOA will be recruited at Gia Dinh People's Hospital using a convenient sampling method. Eligible participants are 50 years or older, diagnosed with KOA, and experiencing chronic knee pain. They will complete the VIET-PSEQ and other health-related questionnaires during an in-person interview. The study will assess internal consistency (using Cronbach's alpha), test-retest reliability (by re-assessing a subgroup after 72 hours), and convergent validity by correlating VIET-PSEQ scores with EQ-5D-5L utility index. Additionally, linear regression analysis will examine how age, sex, pain severity, and education level influence pain self-efficacy. The goal is to determine whether VIET-PSEQ is a reliable and valid tool for measuring pain self-efficacy in Vietnamese patients with KOA.
