Vietnamese Pain Self-Efficacy Questionnaire for people with knee osteoarthritis.

What this trial studies
Researchers will recruit 173 patients aged 50 and older with diagnosed knee osteoarthritis at Gia Dinh People's Hospital and have them complete the Vietnamese PSEQ along with the EQ-5D-5L and other health questionnaires in an in-person interview. Internal consistency will be estimated using Cronbach's alpha and a subgroup will repeat the questionnaire after 72 hours to measure test-retest reliability. Convergent validity will be examined by correlating VIET-PSEQ scores with the EQ-5D-5L utility index, and linear regression will explore relationships with age, sex, pain severity, and education level. The study uses convenient sampling and excludes people with recent acute flares or severe psychiatric disorders.
Who should consider this trial
Good fit: Ideal candidates are Vietnamese-speaking adults aged 50 or older with a confirmed diagnosis of knee osteoarthritis, chronic knee pain (VAS ≥ 1), ability to perform daily activities, and willingness to complete questionnaires in person.
Not a fit: People with recent acute knee pain flares, severe psychiatric disorders, inability to read Vietnamese, those under 50, or those without confirmed knee OA are unlikely to receive benefit from this validation effort.
Why it matters
Potential benefit: If the VIET-PSEQ proves reliable and valid, clinicians and researchers in Vietnam will have a culturally appropriate tool to measure patients' confidence in managing knee pain and help guide care.
How similar studies have performed: The original PSEQ has been successfully validated in many languages and clinical groups, so translating and validating the PSEQ is a common and generally successful approach.
Eligibility criteria

Inclusion Criteria: Participants will be eligible for inclusion if they meet all of the following conditions: * Age ≥ 50 years. * Diagnosis of knee osteoarthritis (OA) according to the criteria of the American College of Rheumatology (ACR), confirmed by: 1. application of ACR criteria by the investigator at the time of enrollment; or 2. a prior diagnosis documented in medical records by a rheumatologist or musculoskeletal specialist. * Presence of chronic pain related to knee OA, with current pain intensity ≥ 1 on the Visual Analog Scale (VAS). * No acute flare of knee pain within the past 2 weeks. * Ability to perform activities of daily living (with or without assistance). * Ability to read, understand, and complete questionnaires in Vietnamese. * Willingness to participate and provide informed consent. Exclusion Criteria: Participants will be excluded if they meet any of the following conditions: * Diagnosis of severe psychiatric disorders (e.g., schizophrenia, severe anxiety disorders). * Presence of cognitive impairment that interferes with the ability to comprehend or answer the questionnaire. * Diagnosed with systemic inflammatory diseases such as rheumatoid arthritis, systemic lupus erythematosus, or gout. * Presence of other chronic pain conditions (unrelated to knee OA) that are predominant and significantly affect mobility and daily functioning. * History of intra-articular injection or knee surgery within the past 3 months. * Questionnaire (PSEQ) with ≥ 20% of items missing or invalid.
