Comprehensibility, reliability, validity, and responsiveness of the Thai version of the Health Assessment Questionnaire in Thai patients with rheumatoid arthritis

Abstract: Introduction The Health Assessment Questionnaire Disability Index (HAQ-DI) is a commonly used instrument to assess functional status of patients with rheumatoid arthritis (RA). Translations and adaptations of the HAQ-DI have been carried out for use with RA patients in several countries. The objective of this study was to evaluate the psychometric properties of the Thai version of the HAQ-DI (Thai HAQ) in Thai patients with RA.

“…Demographic data, clinical manifestations, and variables including gender, age, occupation, marital status, education, comorbidity, tobacco use, alcohol use, disease duration, pain score, patient and physician global assessment of disease activity measured on a 10 cm visual analog scale (VAS), number of tender joints, number of swollen joints, erythrocyte sedimentation rate, rheumatoid factor (RF), anti‐citrullinated peptide (CCP) antibodies, and radiographic evidence of hand and/or feet erosion were collected and analyzed. Disease activity and functional status were evaluated using the Disease Activity Score of 28 joints (DAS28) and the Thai version of the Health Assessment Questionnaire (HAQ), respectively. The Thai version of the EuroQoL 5‐dimensional questionnaire (EQ‐5D) was used to assess health‐related quality of life (HRQoL) .…”

“…The internal consistency (Cronbach alpha of .927) was also comparable to Japanese (0.927), Thai (0.91), Chinese (0.86) and Korean (0.95) versions with Cronbach alpha values ranging from 0.86 to 0.95.…”

“…Although the correlations were not as strong as expected, the results indicate an adequate construct validity of Nepali HAQ with moderate association with other parameters tested. Japanese (0.92), 3 Korean (0.99) 12 and Thai (0.89) 13 versions, but it was comparable to the Tunisian (0.84), 14 Chinese (Spearman correlation 0.84) 15 and Arabic (0.81) 16 versions. For most items, the mean response in the second visit was less than the first visit which cannot be explained by treatment change but could be due to physician's suggestions on rest, hot fomentation and intake of nonsteroidal anti-inflammatory drugs.…”

“…It is easily administered and widely used, with a high reliability and validity for a variety of rheumatic diseases, including rheumatoid arthritis (RA), ankylosing spondylitis (AS) and PsA . Although the Thai version is available, it has been validated in only patients with RA . The objective of this study was to validate the Thai version of the HAQ for patients with PsA.…”
