The psychometric properties of the Passion Scale

The Passion Scale (PS) is a self-report tool to measure passion which involves 8 items and concentrates on personal interest in a specific area, subject or skill. The present study's goal was to determine the psychometric properties of the PS with regard to the Iranian sample. The research methodology was descriptive and the sample included 684 people (377 women and 307 men) chosen on a non-random available basis and they responded to the scale of the research. The internal consistency and reliability of the research were measured using Cronbach's omega and alpha. The validity of the construct and the convergent validity was determined and verified for this scale using confirmatory factor analysis. The results showed that the PS has proper internal consistency and composite reliability. Meanwhile, the face and content validity of the questionnaire was assessed and confirmed. The validity of the construct and the convergent validity was determined and verified for this scale using confirmatory factor analysis. An analysis of the correlation matrix showed a positive correlation between the PS and the Grit perseverance scale (Grit-s) and its factors (p < 0.01). Meanwhile, the independent T Test was used in order to examine the difference between the scores of the men and women in the PS. The findings showed that the mean of women's score was higher that men's. Overall, this research suggested that the PS has optimal psychometric properties when it comes to the Iranian sample and that the scale could be applied with a great deal of confidence to the Iranian sample.
