The Reliability And Validity Of DSM-5 Level 1 Cross-cutting Symptom Measure-child In China

Objective: To verify the reliability and validity of Parent/Guardian-Rated DSM-5 Level 1 Cross-cutting Symptom Measure—Child Age 6-17(DCSM-C),and provide reference for its application and revision in China.Methods: Using stratified(gender,age and health status)convenient sampling method,371 volunteers(183 men,188 women)of 6-17-year-old children and adolescents,including 123 healthy controls(61 boys,62 girls),126 mental disorders(66 boys,60 girls)and 122 physical diseases(56 boys,66 girls)were recruited from Wuxi mental health hospital,general hospital or community.The Parent/Guardian-Rated DSM-5 Level 1 Cross-Cutting Symptom Measure—Child Age 6-17(DCSM-C),The Child Health Questionnaire-28(CHQ-28),Clinician-Rated Dimensions of Psychosis Symptom Severity(CDPSS),World Health Organization Disability Assessment Schedule 2.0(WHODAS2.0).After the interval of 1-2 weeks,20 people were selected from each group,and they were assessed by DCSM-C again.All the subjects participated voluntarily and got the informed consent of their parents and guardians.After the data collection,SPSS22.0 was used for data processing and statistical analysis to calculate the internal consistency reliability,retest reliability,structural validity and criterion related validity of the scale.Results: 1.The Cronbach's alpha coefficient of DCSM-C was 0.82,the split half reliability was 0.90,and the retest reliability is 0.93.2.The structural validity of the cross-border symptom scale for children was 0.708,and the correlation between DCSM-C and CHQ-28,CDPSS,WHODAS2.0 was r = 0.71,r = 0.58,r = 0.57(P < 0.01).3.The results of four psychological tests in three groups were statistically significant(P < 0.05),the DCSM-C score of the mental disorder group was higher than that of the physical disease group and the control group,the difference was statistically significant(P < 0.05),the CHQ-28 score of the mental disorder group and the physical disease group was lower than that of the control group,and the scores of the other three tests were higher than that of the control group,the difference was statistically significant(P < 0.05).There were significant differences in the scores of whodas2.0,chq-28 and CDPSS between the mental disorder group and the physical disease group(P < 0.05).4.Except for the three items of substance abuse and suicide ideation,the other 22 items of DCSM-C were correlated with the total score of the scale(r = 0.132-0.767)(P < 0.05).5.When the total score of DCSM-C is used to screen the mental disease group and the control group,the cutoff value was > 16,the sensitivity was 88.10%,and the specificity was 95.93%.When the total score of DCSM-C was used to distinguish the body disease group and the control group,the cutoff value was > 15,the sensitivity was 69.67%,and the specificity was 93.50%.Conclusion: 1.The internal consistency,structure validity and criterion related validity of DCSM-C is good.2.The DCSM-C has higher sensitivity and specificity,and better screening effect for screening children with mental disease.
