Validity and reliability of the Turkish version of the early symptom measurement of post-stroke depression short form...

The present methodological study was conducted to adapt the Early Symptom Measurement of Post-Stroke Depression developed by Li et al.¹ into Turkish and to examine its validity and reliability. This study was conducted between September and December 2025 with a final sample of 120 patients diagnosed with stroke. Data were collected using a Personal Information Form and the Early Symptom Measurement of Post-Stroke Depression-Short Form (ESMPSD-SF). Expert opinion was obtained to assess content validity, and the Content Validity Index (CVI) was calculated. Construct validity was evaluated using the Kaiser-Meyer-Olkin (KMO) test, Bartlett's test, and Confirmatory Factor Analysis (CFA). Reliability was assessed using Cronbach's alpha, item-total correlations, and the test-retest method, which was performed with 30 participants after a 15-day interval. Content validity was high (CVI = 0.99). The KMO value (0.848) and Bartlett's test (χ² = 439.024; p < 0.001) confirmed suitability for factor analysis. CFA indicated good model fit (RMSEA = 0.028, CFI = 0.99, TLI = 0.99). The overall Cronbach's alpha coefficient was 0.845, indicating good internal consistency. Test-retest reliability was excellent (ICC = 0.993). The Turkish version of the ESMPSD-SF, consisting of four subscales and 12 items, was found to be a valid and reliable measurement tool for Turkish culture.
