Validity and reliability of the Turkish version of the early symptom measurement of post-stroke depression short form (ESMPSD-SF)
摘要
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.
