Aim: This study aimed to determine psychometric properties of the Persian version of Temporal Experience of Pleasure Scale. Method: Research method was evaluation using test development and the population consisted of 46000 students at universities of Shahed, Tehran, and the Islamic Azad- Medical Branch; 521 students were selected none randomly based on their availability. To determine the validity of the scale, construct validity was determined via exploratory as well as confirmatory factor analyses and convergent validity via calculating the correlation between the scale and Beck, Steer & Brown’s Depression Inventory-II (1996) and the Social Phobia Inventory Connor, Davidson, Churchill, Sherwood, Foa, & Weisler (2000). The reliability of the scale was measured using Cronbach’s alpha and test-retest coefficient. Results: Exploratory factor analysis suggested the emergence of three factors which were labelled consummators pleasure, abstract anticipatory pleasure and contextual anticipatory pleasure. Confirmatory factor analysis confirmed the three factor structure resulted from exploratory factor analysis and its superiority over the factor structure of the original version amongst Iranian sample (relative χ2= 1.47, GFI= 0.94, AGFI= 0.90, CFI= 0.95, RMSEA= 0.04). For total scale and three extracted factors, Cronbach alphas ranged from 0.62 to 0.82 and the test- retest reliability coefficients ranged from 0.71 to 0.93. TEPS showed significant, albeit weak, negative correlation with Beck’s Depression Inventory-II (r= -0.12, P= 0.006) to (r= -0.21, P= 0.0001) and Connor’s Social Phobia Inventory (r= -0.13, P= 0.002) to (r= -0.21, P= 0.0001). Conclusion: The Persian version of the Temporal Experience of Pleasure Scale has adequate reliability and validity and it can be used for Iranian population.
