This study aimed to adapt the Perth Emotional Reactivity Scale (PERS) and its short form (PERS-S), which assess individual differences in emotional reactivity to positive and negative emotions with three subscales (activation, intensity, and duration), into Turkish. Method: Participants (N=393, 73% female; for usable data) completed the PERS and other related measures including positive and negative affect, emotion dysregulation, and psychological distress symptoms. Results: Confirmatory factor analyses supported the 6-factor structure of both the PERS and PERS-S. Results also showed that the Turkish versions of the scales can be used as 6- or 2-factor scales, depending on the research interest (PERS: χ2/df = 4.15, CFI=0.9, NFI= 0.9, RMSEA= 0.09 [0.085 - 0.094]; PERS-S= χ2/df = 3.19, CFI=0.96, NFI=0.94, RMSEA= 0.075 [0.067 - 0.083]). The positive and negative emotional reactivity subscales showed satisfactory internal consistencies (all ’s > .63) and two-week test-retest reliability levels (all r’s > .62) and were correlated with emotion dysregulation, psychopathology, and positive/negative affect. Conclusion: The Turkish versions of PERS and PERS-S are reliable and valid tools for measuring individual differences in emotional reactivity.}, number={Supplement 1}, publisher={Lut TAMAM}, organization={This study was not funded by any agency.}
