Abstract

Objective: The present study was conducted in order to investigate the psychometric characteristics of Affective Reactivity Index (ARI) and the prevalence of irritability in adolescents.

Methods: The method of this research was descriptive-correlation. For this purpose, 402 male and female first period of high school were randomly selected in a multi-stage method in the city of Ardabil, where they were studying in 1401-1402 year, as a sample group and were asked affective reactivity index, Stringer et al and anxiety, depression and stress scale Lavibond and Lavibond answered. The data were analyzed using the confirmatory factor analysis method.

Findings: The results showed that content validity experts confirmed the emotional excitability scale. 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.

Conclusion: Overall, the findings of the research show that the emotional reactivity index, like the scale-building research, consists of one factor and has acceptable reliability and validity, as a result, it can be used to measure irritability in used destructive mood disorder.
