Abstract
Objective: This study examined the psychometric properties of the Cantonese version of the SarQoL® questionnaire.
Participants: A total of 118 (including 60 non-sarcopenic and 58 sarcopenic) community-dwelling older adults aged 65 years or above with Cantonese as their mother tongue.
Methods: Translation and cultural adaptation of the SarQoL were conducted using a standardized protocol. To validate the Cantonese SarQoL, psychometric properties including discriminative power, reliability (including internal consistency and test-retest reliability), and construct validity (including convergent and divergent validity), as well as floor and ceiling effects, were assessed.
Results: The translation of the questionnaire was completed without significant difficulties. Results indicated that the Cantonese SarQoL had (1) good discriminative power (sarcopenic participants had lower overall scores, mean = 66.1 vs 75.0, p < 0.001; the overall score was negatively predictive of the presence of sarcopenia, adjusted OR = 0.949, 95% CI = [0.912, 0.983]), (2) good internal consistency (Cronbach's alpha = 0.835; correlations between domain and overall scores ranged from 0.576 to 0.868), (3) excellent test-retest agreement (intraclass correlation coefficient = 0.801), (4) good construct validity (convergent: moderate to strong correlations were found between the overall score and almost all of the SF-36 and EQ-5D domains; divergent: weaker correlations were found between the overall score and SF-36 social functioning, ρ = -0.098, and EQ-5D self-care, ρ = -0.331), and (5) no floor or ceiling effect.
Conclusion: The Cantonese SarQoL is valid and reliable, and thus can be used as an interviewer-administered questionnaire for assessing sarcopenia-specific quality of life in fieldwork practice.
期刊介绍：
Clinical Interventions in Aging, is an online, peer reviewed, open access journal focusing on concise rapid reporting of original research and reviews in aging. Special attention will be given to papers reporting on actual or potential clinical applications leading to improved prevention or treatment of disease or a greater understanding of pathological processes that result from maladaptive changes in the body associated with aging. This journal is directed at a wide array of scientists, engineers, pharmacists, pharmacologists and clinical specialists wishing to maintain an up to date knowledge of this exciting and emerging field.
