Psychometric characteristics of Anger Rumination Scale (ARS) in Students

After happening anger events, we experience repetitive thoughts that can be influenced in mind for long times and these repetitive thoughts have negative psychological consequences. The aim of present study was to investigate of the psychometric characteristics of Anger Rumination Scale amongst a sample of ShahidChamran University students. In this descriptive study, the sample has been carried out on 273 students of ShahidChamran University which were selected through stratified multi-stage random sampling. The reliability coefficients were calculated by three different Cronbach Alpha, Spearman – Brown and Guttmanspiliting and to determine the validity of the scale, Confirmatory Factor Analysis and Concurrent Validity were used. For analysis the dataSpss version 19 and Amos version 20soft ware were used and significant level was 0/05. The findings of this study indicate that the scale has desired reliability and validity. (RMSEA= 0/63, reliability by Cronbach Alpha=0/90, Spearman – Brown spiliting Alpha=0/85 and Guttmanspiliting Alpha = 0/84 were calculated). Confirmatory Factor Analysis showed that the four factor model of Anger Rumination Scale fits among the students sample. The results of the present study have provided an acceptable reliability and validity evidence for the Anger Rumination Scale in ShahidChamran University students which can be applied in future researches.
