Abstract:
Objective To evaluate the reliability and validity of the Chinese version of the Remission Evaluation and Mood Inventory Tool (REMIT) in outpatients with depression.Methods A total of 9 948 depressive outpatients who met with the diagnostic criteria of the 3rd version of Chinese Classification of Mental Disorders (CCDM-3) were included in the study.REMIT were administered at baseline,and week 2,week 4 after baseline,and 509 completed retest within 1 week interval after the first interview.The reliability was evaluated by cronbach' α coefficient and the intraclass correlation coefficients (ICC).The Hamilton Depression Rating Scale for Depression (HAMD17) was administered to test the criteria-related validity and discriminant validity.The exploratory factor analysis (EFA) and conformative factor analysis (CFA) was used to confine the construction validity.And data from follow-up was used to assess the sensitivity to change.Results The REMIT was found to possess good test-retest reliability (ICC:0.56-0.79),as well as good internal consistency (cronbach α:0.82,item-total score correlaiton coefficents:0.49-0.67).A 2-factor construciton was confirmed.The summary and reduction of REMIT score was both closely correlated with those of HAMD17 score with a coefficent of 0.52-0.73(all P＜0.01).The difference of REMIT was statistically significant between patients with varied severity of depressive symptoms at all visits (F=452.7-1 468.4,all P＜0.01).The item score and total score of REMIT (baseline:12.5±2.8,week 2:8.5± 2.3,week 4:5.2 ± 2.5) were decreased with treatment (F=11 282.8-32 445.1,all P＜0.01),with a high standardized mean difference (1.6-2.7) between pre and post treatment.Conclusion The Chinese version REMIT is good in reliability and validity with sensitivity to change.It can be administered to evaluation the outcome of depression treatment as a complementary tool to symptom assessment,and the REMIT has met the original needs of the designers.
