the persian checklist of pleasant events (pcpe): ‎development, validity and reliability

objective: experiencing ‎pleasant events during daily life ‎has a significant positive role in ‎the personal mental health and ‎acts as a keystone for “behavioral ‎activation” (ba) interventions. ‎there are serious differences in ‎the pleasant event schedules in ‎different cultures and countries. ‎we aimed to develop a persian ‎checklist of pleasant events ‎‎(pcpe) to provide and validate a ‎culturally compatible checklist for ‎iranians.‎ methods: to develop a checklist ‎of pleasant events, inspired by ‎pleasant events schedule (pes) ‎‎(macphillamy & lewinsohn, ‎‎1982), we held three focused ‎group discussions with 24 normal ‎healthy participants from both ‎genders (female = 12) and asked ‎them to mention as much ‎pleasant events as possible. ‎when the list reached saturation ‎level, the inappropriate items with ‎respect to legal, cultural and ‎religious concerns were omitted. ‎the final checklist of pcpe ‎consists of two subscales: ‎frequency (frequency of events ‎during last month) and ‎pleasantness (perceived ‎pleasantness of events). 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.
