Aim This study aimed to culturally adapt and validate the Turkish version of the Short Musculoskeletal Function Assessment Questionnaire (SMFA‐TR) which primarily assesses the functional status of patients. Methods The translation and cross‐cultural adaptation of SMFA to Turkish was made by the standardized procedure and tested for clinimetric quality. The following analyses were made to evaluate clinimetric quality of the SMFA‐TR: reliability with factor analysis and Chronbach's α (construct validity), correlations between SMFA‐TR and Short Form (SF)‐36 (concurrent validity), test‐retest reliability (intraclass correlation analyses), floor and ceiling effects. The questionnaire was applied to 166 patients with musculoskeletal problems. All patients filled in the SMFA‐TR and the validated Turkish SF‐36 questionnaire. Forty‐two patients returned to complete the same questionnaires at 10 days. Results Factor analysis revealed a 4‐factor structure of the SMFA‐TR. Cronbach's α values were over 0.88 for both original subscales (dysfunction and bother) of the SMFA. Internal consistency (0.88‐0.94) and test‐retest reliability coefficients (0.90‐0.98) were high for both subscales. Turkish SF‐36 questionnaire conventional subscales showed significant correlations with SMFA‐TR subscales. No floor or ceiling effects were found. Conclusion The Turkish version of the SMFA was found to be reliable and valid for Turkish‐speaking patients with musculoskeletal injuries or disorders.
