Abstract

Objectives The Musculoskeletal Health Questionnaire (MSK-HQ) is a short, targeted instrument that effectively captures the complex treatment goals essential for managing Musculoskeletal Disorders (MSDs). However, it remains unavailable in any Nigerian language. This study aimed to translate and culturally adapt the MSK-HQ into Yoruba language, and to assess its psychometric properties. Methods The first stage of this study involved translating the English MSK-HQ into Yoruba using the Guillemin criteria. A correlational study design was employed for psychometric testing of the translated version among individuals with MSDs, while 40 patients participated in the reliability testing phase. The Short Form (SF-12) and visual analogue scale (VAS) were utilised to assess the convergent and divergent validity of the tool. Data were analysed using descriptive and inferential statistics. The alpha level was set at p<0.05. Results Seventy participants (mean age of 32.7±12.4 years) took part in the study. The MSK-HQ (MSKHQ-Y) demonstrated acceptable concurrent validity (r=0.968; p=0.001), but mixed construct validity for convergent (r=0.493; p=0.001; r=-0.472; p=0.001; r=0.667; p=0.001; r=0.625; p=0.001; r=0.618; p=0.001; r=-0.303; p=0.007; r=-0.308; p=0.006; r=0.015; p=0.898; r=0.703; p=0.001) and negative divergent validity (r=-0.598; p=0.001). Regarding convergent validity, the physical health domain (r=0.703; p=0.001) and role limitations due to physical problems (r=-0.472; p=0.001) showed the highest and lowest scores, respectively. The test-retest reliability and internal consistency (Cronbach’s alpha) of the MSKHQ-Y were r=0.989 and p=0.001, with r=1.000 for item-by-item variables. Model modification included eight correlation residuals ranging from 0.08 to 0.40. The factor loadings of the 2-factor model were excellent, and both models exhibited excellent composite reliability. Conclusions The MSKHQ-Y is a reliable tool with strong psychometric properties for evaluating musculoskeletal health in Yoruba-speaking populations, playing a critical role in managing MSDs.
