Reliability and validity of the Chinese version of CTQ-SF

Objective To explore there liability and validity of the Chine seversion of Child Trauma Questionna rire Short Form(CTQ-SF),and to provide a theo retical foundation for its application.Methods A survey was conducted among 1892 teenagers with the Chinese version of CTQ-SF and there liability and validity of the CTQ-SF were analyzed.Results The total Cronbachs alpha coefficient and splithal freliability of the CTQ-SF were higher than 0.70.The Cronbachs alpha coefficient and split half reliability of each subscale were higher than 0.60 exceptphysical neglect.The average correlation coefficient was 0.20 and the average correlation coefficien to feach subscale ranged from 0.11 to 0.37.The correlation between general scale and subscales ranged from 0.54 to 0.80 with a significant correlation(P<0.01).The correlation coefficients between general scale and subscales were more than the corre lation coeffic ients between the subscales.The correlation coefficients bettween the subscales ranged from 0.18 to 0.50(P<0.01 for all).Exploratory factor analyses selected a four factor solution,accounting for 66.12% of the variance.Factor communalities were higher than 0.40.The four factors represented all of the items.Conclusion The Chinese version of CTQ-SF is a good psychometric instrument for the evaluation o f Chinese childhood abuse.But the physical neglect requires further miprovement.
