Objective: Early detection of sarcopenia using accessible screening tools is essential but challenging due to the limitations of current instruments. The purpose of this study was to validate the Mini Sarcopenia Risk Assessment (MSRA-7 and MSRA-5) questionnaires in Turkish. Methods: A total of 157 community-dwelling older adults were consecutively recruited from an outpatient geriatric clinic. Muscle strength and mass were measured using handgrip strength, chair stand test, and bioelectrical impedance analysis. Since only one participant met the criteria for confirmed sarcopenia, analyses focused on probable sarcopenia as defined by the European Working Group on Sarcopenia in Older People (EWGSOP2). Reliability was assessed with Cronbach’s alpha and intraclass correlation coefficients (ICCs). Construct validity was evaluated via Spearman correlation with the SARC-F questionnaire. Diagnostic performance was analyzed using ROC curves. Results: The Turkish MSRA-7 and MSRA-5 demonstrated acceptable internal consistency (Cronbach’s alpha: 0.650 and 0.705, respectively) and excellent reliability (ICC range: 0.971–0.992). Both versions showed strong negative correlations with SARC-F (r = -0.767 for MSRA-7; r = -0.781 for MSRA-5, p < 0.001), confirming construct validity. ROC analysis yielded AUC values of 0.688 for MSRA-7 and 0.721 for MSRA-5. The MSRA-5 showed slightly superior diagnostic accuracy. Conclusion: The Turkish adaptations of the MSRA-7 and MSRA-5 demonstrate validity and reliability as instruments for screening probable sarcopenia. Given its stronger internal consistency and diagnostic performance, in clinical practice, the MSRA-5 could be the preferred tool for early identification and intervention in older adults in Türkiye.
