Psychometric properties of Persian short version of the five factor impulsive behavior scale

Given the importance of identifying people at risk of dangerous behaviors and necessity of providing valid measures in this area, present study aimed to evaluate the psychometric properties and factor structure of short Persian version of the five factor impulsive behavior scale. 352 participants living in Tehran were selected. The participants filled out Urgency, Premeditation, Perseverance, Sensation seeking, and Positive urgency (UPPS-P) Impulsive behavior scale, short form of UPPS-P Impulsive behavior scale, and difficulties in emotion regulation scale. Internal consistency reliability of impulsive behavior scale ranged between 0.52 and 0.75. The results of exploratory factor analysis confirmed the factor structure of this scale, with the exception of combining two dimensions of urgency under a factor. Criterion validity showed significant positive correlation between the difficulty in emotion control and factors of impulsivity by examining the association between scores of the factors of impulsivity with difficulty in emotion control scale. This findings indicated that impulsive behavior scale has acceptable validity and reliability and can be used to predict a variety of risky behaviors. However, given the low number of items of this form (20 items) compared to the long form, generalization of this study findings should be done with cautious.
