Abstract:
Objective:To assess the psychometric properties of the Chinese version of 12-item immediate mood scale(IMS-12) in patients with depression.Methods:From January to June 2018, a total of 459 patients with depression recruited from an outpatient clinic by convenient sampling approach.All the subjects were assessed by the Chinese version of the IMS-12, and 43 of them were assessed again at the end of the first week.The 16-item quick inventory of depressive symptomatology (QIDS-SR16), and the generalized anxiety disorder scale-7(GAD-7) were used as validity indicator.The factor structure of the scale was evaluated by exploratory and confirmatory factor analyses.The internal consistency of the Chinese version of the IMS-12 scale was evaluated by Cronbach’s alpha coefficient.The intraclass correlation coefficient (ICC) was used to evaluate test-retest reliability.Pearson’s correlation coefficient was used to evaluate calibration validity.The softwares of SAS 9.4 and Mplus 8.5 were used for statistical analysis.Results:The exploratory factor analysis indicated that the fitting result of the two-factor model was good(including depression and anxiety factors). The results of the confirmatory factor analysis indicated that the factor model fit well and met the reference standard ( χ2/ df=2.82, CFI=0.936, TLI=0.920, RMSEA=0.088). The Cronbach’s alpha coefficient of the Chinese version of the IMS-12 was 0.95, and the ICC for test-retest reliability was 0.85.The correlation coefficients of the total IMS-12 score with the QIDS-SR16 score and with the GAD-7 score were 0.69 and 0.70, respectively. Conclusion:The Chinese version of the IMS-12 has good reliability and validity and is suitable for the clinical assessment of depressive and anxiety symptoms in patients with depression.
