ABSTRACT
Objective To evaluate the reliability and validity of the brief version of dysfunctional beliefs and attitudes about sleep(DBAS-16).Methods Participants were out-patients who with insomnia or insomnia comorbided depression disorder or anxiety disorder.All of them were assessed by DBAS-16,Pittsburgh sleep quality index (PSQI),self-rating depression scale (SDS),self-rating anxiety scale (SAS).30 of them were evaluated by DBAS-16 two weeks later.Results 230 patients were assessed,212 pieces of questionnaire with integral answers were collected,The Cronbach α Coefficient of DBAS-16 was 0.786,the Cronbach α coefficients of four subscales were 0.424-0.703.Split-half reliability coefficient of total score was 0.775,split-half reliability coefficient of four subscales were 0.424-0.719.Item-total correlation coefficients ranged from 0.602 to 0.283(all P＜0.05).The testretest reliability coefficient was 0.928,and coefficient of each subscales ranged from 0.709 to 0.907 (all P＜0.05).Confirmatory factor analysis was used to estimate the construct validity.The fit indices:x2/dfwas 1.623,the adjusted goodness of fit index (AGFI) was 0.882,root mean square error of approximation (RMSEA) was 0.054,incremental fit index (IFI)was 0.899,non-normed fit index (NNFI) was 0.871,comparative fit index (CFI) was 0.895.Total DBAS-16 score significantly correlated with PSQI(r=-0.311,P＜0.01),SDS(r=-0.192,P＜0.01),SAS(r=-0.162,P＜0.01).Conclusion The reliability and validity of the brief version of DBAS-16 are adequate.
ABSTRACT
Objective To explore the coping styles and family environment in patients with depression.Methods 90 patients with depression were evaluated with CSQ and FES-CV.Results There were significant differences in the family environment between depression group and normal control group(P＜0.01).The factor scores of seeking-help and solving question in depression group positively correlated with the factor scores of family intimacy and success(r=0.29,0.32,0.27,0.31,P＜0.05).The factor score of self-accusation in depression group negatively correlated with the factor score of affection expression(r=-0.27,P＜0.05).Conclusion The coping styles are associated to family environment in patients with depression.
