The study of psychometric properties of emotion reactivity scale in Arak university ‎students

The purpose of this study was to investigate the psychometric properties of Emotional Reactivity Scale in Iranian students.

This study was a survey study conducted on 625 undergraduate students of Arak University. The classical theory of test analysis and item-response theory were used to analyze the data. In the classical approach, the validity of the instrument was investigated using three methods of face validity, convergence- discriminate and construct validity. Reliability of this scale was also calculated by internal consistency and quasi-test and test-retest method.

The relationship between emotion reactivity scores and high-risk behaviors (r = 0.16) and negative mood (r = 0.47) was positive and significant and between emotion reactivity and Resilience (r = -0.30) was negative and significant, indicating convergent and discriminate validity of the scale, respectively. The results of confirmatory and exploratory factor analysis indicated the appropriate factor structure of this scale. In the item -response theory, statistics also confirmed the fit of the model.

The Persian version of the emotion reactivity scale appears to be valid and reliable for use in future studies specially for predicting mental disorders and also as a variable which can be related to difficulties in emotion regulation in Iran.Keywords: emotion reactivity scale, psychometric properties, university students
