Abstract:
Objective:To examine the validity and reliability of the DSM-5 Social Anxiety Disorder Severity Scale(SAD-D)in a Chinese adult population.Methods:The Chinese version of the DSM-5 Social Anxiety Disor-der Severity Scale was administered via online data collection platform Credamo to 300 adults(Sample 1,for item analysis,exploratory factor analysis and item selection of brief version of SAD-D)and 528 adults(Sample 2,for confirmatory factor analysis,criterion validity test,measurement invariance analysis and internal consistency reliabil-ity analysis for both SAD-D and its brief version).Criterion validity was tested with the Social Phobia Scale(SPIN)and Personal Report of Confidence as a Speaker(PRCS).A brief version of the scale was developed by u-sing the Ant Colony Optimization(ACO).A retest was conducted with 152 participants from Sample 2 after three weeks.Results:Exploratory factor analysis indicated that the SAD-D was a unidimensional scale with factor load-ings ranging from 0.49 to 0.82,and the results of the confirmatory factor analysis also supported the unidimension-al structure(x2/df=3.49,RMSEA=0.069,CFI=0.971,TLI=0.962,SRMR=0.028).The scores of Chinese version of the SAD-D were positively correlated with the SPIN scores(ICC=0.70,P＜0.001)and PRCS scores(ICC=0.73,P＜0.001).The Cronbach'α of the scale was 0.92,and the retest reliability was 0.85.The scale dem-onstrated cross-gender measurement invariance(△CFI＜0.01,△RMSEA＜0.01).The brief version of the SAD-D was selected as items 2,5,and 6,and its Cronbach'α coefficient was 0.86.Conclusion:The Chinese version of the SAD-D has satisfactoryvalidity andreliability,making it suitable for the assessment of social anxiety symptoms with Chinese adults.
