Evaluation of the construct reliability and validity of the DSM-5 Self-Rated Level 1 Cross-Cutting Symptom Measure-Chinese version in maintenance hemodialysis patients

OBJECTIVE: The study aim was to assess the construct reliability and validity of the internal structure of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition Self-Rated Level 1 Cross-Cutting Symptom Measure (CCSM)-Chinese version in maintenance hemodialysis (MHD) patients, and to clarify whether the CCSM is suitable for patients with psychological issues. METHODS: Participants were 190 MHD patients. Structural equation modelling was used to establish a measurement model to confirm the reliability and validity of the internal structure of the CCSM-Chinese version, and to compare it with the Chinese version of the Symptom Checklist-90 (SCL-90). RESULTS: Of the 13 CCSM domains, 8 showed stability and validity in the initial screening of psychological symptoms. Although the Chinese version of the SCL-90 is widely used, the measurement model of the 8-domain CCSM was a better fit than the SCL-90 (CCSM: chi-square = 35.668, chi-square/degrees of freedom [CMIN/df] = 1.877; root mean square error of approximation [RMSEA] = 0.061; adjusted goodness of fit index [AGFI] = 0.931 vs. SCL-90: chi-square = 89.159, CMIN/df = 2.972; RMSEA = 0.084; AGFI = 0.879). CONCLUSION: The Chinese version of the CCSM is a useful rapid screening tool to detect psychological symptom risk in MHD patients.
