The total ‎score consists of frequency ‎multiplied by pleasantness. To ‎test the reliability and validity of ‎the checklist, the PCPE, ‎Depression, Anxiety and Stress ‎Scale (DASS), the Persian ‎version of WHO Quality of Life ‎and the Demographic ‎Questionnaire were administered ‎in a sample of 104 participants ‎‎(50 male and 54 female).‎ Results: Frequency, ‎pleasantness and the total scores ‎of PCPE showed high levels of ‎internal consistency (Cronbach’s ‎alpha, .976, .976 & .974, ‎respectively). Further support for ‎the convergent validity of the ‎PCPE was obtained via ‎moderate negative correlations ‎with depression, anxiety, stress ‎scores in DASS and positive ‎correlation with quality of life as ‎well as respondent’s perceived ‎happiness. There were negative ‎correlations between frequency, ‎pleasantness and total scores ‎and age of the participants ‎‎(Pearson correlation coefficient, r ‎‎= -.194, p<0.05; r = -.270, p<0.01 ‎& r = -.234, p<0.05, respectively).‎ Conclusion‏:‏‎ PCPE as an ‎assessment tool has shown to ‎have good reliability and validity ‎among Iranians. Further steps ‎should be taken to validate this ‎instrument in different ‎psychopathologies such as ‎depression, addiction and ‎obesity. https://ijps.tums.ac.ir/index.php/ijps/article/view/584 https://ijps.tums.ac.ir/index.php/ijps/article/download/584/537
