Abstract
ObjectiveTo assess the psychometric properties of the Chinese version of 12-item immediate mood scale(IMS-12) in patients with depression.
MethodsFrom 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.
ResultsThe 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.
ConclusionThe 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.
