Convergent validity showed that this scale had a significant relationship with depression, anxiety and stress, and among them, it had the highest relationship with depression (p<0.01). Confirmatory factor analysis showed that all the items of this scale significantly loaded on one factor and all the fit indices of the model had an acceptable level (RAMSEA=0.05). Cronbach's alpha coefficient of this scale was 0.92, which indicates the appropriate reliability of this scale. Also, the findings showed that a total of 23.13% of the sample group had irritability. This rate was 25.65% in boys and 11.69% in girls.
