Objective: To validate the Malay version of the Health Assessment Questionnaire (Malay‐HAQ) for use in Malay‐speaking rheumatoid arthritis (RA) patients in the Malaysian setting. The HAQ – Disability Index has been validated in several languages, but not in Malay.
Methods: The original HAQ was modified and translated into Malay by two translators, one of whom was aware of the objectives of the Questionnaire and the other as a lay translator. Two sets of Malay‐HAQ were distributed to RA patients during their routine follow‐up visits; one set to be completed immediately and another set to be completed 2 weeks later. A total of 61 patients completed the two sets of Malay‐HAQ. The data collected was analysed using SPSS V. 11.0. Reliability of the data was evaluated using the test‐retest method and internal consistency was assessed by Cronbach's alpha.
Result: The study showed that the Malay‐HAQ is feasible and reliable. The Spearman's correlation coefficient ranged from 0.65 to 0.82, while the internal consistency was 0.88–0.92.
Conclusion: The Malay‐HAQ is a sensitive, reliable and valid instrument for the measurement of functional status in RA patients in a Malay setting.
This research disentangles and validates the underlying factorial-structure of Digital Experiential Value (DEV) measurement scale and subsequently investigate its psychometric properties. The analysis was based on a sample of 400 mobile shoppers, collected via online questionnaire. To confirm and validate the factorial structure and assess the psychometric properties of DEV, confirmatory factor analysis (CFA) was executed. To establish the homological validity of DEV, a structural model was developed to examine the effect of DEV on Total Digital Experience Quality (TDEQ). It is unveiled that DEV is a 2nd-order formative seven-factorial structure. Constructs and its scales has adequately met the psychometric criteria, thus could permit interpretation of results confidently. The findings have important implications for future research directions and management of mobile shopping industry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
