Reliability and validity test of Ruminative Responses Scale in Chinese military personnel and its application

Abstract

Objective To test the reliability and validity of the Ruminative Responses Scale (RRS) in Chinese military personnel. Methods A total of 4 443 military personnel from 2 brigades in the Northern Theater Command were tested using Ruminative Responses scale(RRS), Patient Health Questionnaire (PHQ-9), and Negative Cognitive Processing Bias Questionnaire (NCPBQ). SPSS 22.0 and AMOS 26.0 were used for reliability and validity analysis. Results ① The 3-dimension model fitting indexes of RRS were within the standard range (RMSEA=0.074, GFI=0.887, RMR=0.018, CFI=0.922, IFI=0.922). ② All the scores for each item and factor of RRS showed significant positive correlations with the total score of the questionnaire (r=0.372~0.977, P < 0.01). ③ The correlation coefficients between each factor of RRS and PHQ-9 were 0.604~0.730, and those between each factor of RRS and NCPBQ were 0.615~0.741. ④ It was found that the Cronbach'α coefficients of the RRS were between 0.821 and 0.956, the split-half coefficients were between 0.845 and 0.918, the test-retest coefficients were between 0.671 and 0.894. Conclusion RRS is of high reliability and validity for measurement among military personnel.
