Reliability and validity of the Chinese version of Connor-Davidson resilience scale among coal miners / 中华行为医学与脑科学杂志

ABSTRACT

Objective To examine the reliability and validity of the Connor-Davidson resilience scale (CD-RISC) among coal miners,and explore factors structure and essence. Methods A questionnaire survey was conducted among 731 coal miners by using CD-RISC,Maslach burnout inventory( MBI-GS) and general self-efficacy scale( GSES). Results Twenty-five items of CD-RISC were retained based on the re-sults of exploratory factor analysis,including three factors of stress resistance,sense of competence and optim-ism. CD-RISC factors were significantly correlated with each other,and the correlation coefficient ranged from 0. 623 to 0. 777(P<0. 01). There was also a significant correlation between CD-RISC factors and total score, and the correlation coefficient ranged from 0. 837 to 0. 939(P<0. 01). The fitting index of confirmatory factor analysis were χ2/df=3. 76<5,GFI=0. 884,CFI=0. 909,AGFI=0. 862>0. 8,RMSEA=0. 065,proved that the measured data fitted well with the hypothesized three-factor model. Internal consistency reliability coeffi-cient of the total scale,stress resistance,sense of competence and optimism factors were 0. 942,0. 920,0. 868 and 0. 765,repectively. The CD-RISC scale was positively correlated with GSES and negatively correlated with MBI-GS and its factors named emotional exhaustion and depersonalization. Conclusion The CD-RISC of 25 items for coal miners possesses good reliability and validity.
