Investigation of Psychometric Properties of Misophonia Questionnaire

Misophonia is a condition in which individuals react negatively to sounds that occur in particular situations, but they tolerate other sounds that are frequently much louder. The present research was conducted to investigate of psychometric properties of Misophonia Questionnaire in college students in order to provide a tool for evaluation in the research process and used by researchers and therapists.  The sample of this study was 319 undergraduate students (176 females and 143 male) who were selected from students of Payame Noor University of Ahvaz by multi-stage sampling method. The instruments of this study consisted of Misophonia Questionnaire of Wu, Lewin, Murphy & Storch, Yale-Brown Obsessive Compulsive Scale, Beck Anxiety Inventory (BAI-II) and Beck Depression Inventory (BDI-II).  The internal consistency with Cronbach's alpha and correlation of each questionnaire's items with total score of scale showed acceptable reliability. In addition, confirmatory factor analysis showed that two-factor structure of this scale was appropriate. Furthermore, the results of convergent validity indicated that Misophonia Questionnaire has a significant positive relationship with Yale-Brown Obsessive Compulsive Scale, Beck Anxiety Inventory (BAI-II) and Beck Depression Inventory (BDI-II).  The results showed that Misophonia Questionnaire is a valid and reliable scale for measuring misophonia in Iranian student.
