Assessment of the Emotional Reactivity Through the Positive and Negative Emotions: The Psychometric Properties of the Persian Version of the Perth Emotional Reactivity Scale

Abstract

Background: Emotional reactivity is a key construct for understanding psychopathology. Examining the psychometric properties of the instruments in societies with different cultures can help with their external validity. Objectives: The current study aimed at standardization and validation of the Perth emotional reactivity scale (PERS) in Iranian university students. Methods: The Persian version of the PERS was produced through forward translation, reconciliation, and back-translation. A total of 302 (169 males and 133 females) nonclinical students were selected by convenience sampling method, and completed a set of questionnaires, including the PERS, weight efficacy lifestyle questionnaire-short form (WEL-SF), eating attitude test-16 (EAT-16), self-esteem scale (SES), difficulties in emotion regulation scale-16 (DERS-16), and self-compassion scale (SCS) short-form. The construct validity of the PERS was assessed using confirmatory factor analysis and divergent and convergent validity. Internal consistency and test-retest reliability (a 2-weeks interval) were used to evaluate the reliability. Data analysis was performed using LISREL (version 8.8) and SSPS (version 22) software. Results: All PERS scales and subscales were found with good internal consistency and test-retest reliability in a nonclinical population. The convergent validity and divergent validity were also found good. The results of this study provides the support for the applicability of the six-factor (RMSEA = 0.06, NFI = 0.94, NNFI = 0.96, and CFI = 0.97) and two-factor (RMSEA = 0.07, NFI = 0.94, NNFI = 0.96, and CFI = 0.96) models of the PERS. Conclusions: The PERS showed good validity and reliability and can be useful in assessing emotional reactivity in the Iranian population. The PERS can be promising as a measure to use in emotional-based studies and clinical settings.

Psychometric properties of the Russian version of the Perth Emotional Reactivity Scale-Short Form

“…Необходимо проведение дальнейших исследований в популяции с более разнородными социально-демографическими характеристиками, а также среди клинических групп. Несмотря на эти ограничения, теоретико-эмпирические данные, полученные в ходе данной работы, согласуются с выводами других исследований о психометрических свойствах PERS-S [8,9], что подчеркивает валидность русскоязычной версии PERS-S.…”

“…Исследования с помощью опросников PERS и PERS-S показали, что реактивность негативных эмоций взаимосвязана с нарушениями регуляции эмоций, с пониженными самооценкой и состраданием к себе, в то время как реактивность позитивных эмоций связана с противоположными последствиями для психологического функционирования личности [9]. Обнаружено, что реактивность позитивных эмоций положительно взаимосвязана со способностью личности управлять своим поведением, в то время как реактивностью негативных эмоций -отрицательно [10].…”

Assessing Alexithymia in Adolescents: Psychometric Properties of the Perth Alexithymia Questionnaire in High School Students

“…The psychometric properties of the PAQ have been so far examined across a number of published studies, all with adult samples from either Australia (Greene et al, 2020a(Greene et al, , 2020bFynn et al, 2022;Preece et al, 2018aPreece et al, , 2020c, Chile (Becerra et al, 2021), the United States (Preece et al, 2020b), Iran (Lashkari et al, 2021;Mousavi Asl et al, 2020), Turkey (Bilge & Bilge, 2020), or Singapore (Chan et al, in press). Consistent patterns have emerged supporting the utility of the PAQ across these studies, in that good internal consistency reliability has been obtained for all subscale and composite scores (α > .70), and confirmatory factor analyses have supported a 5-factor structure consistent with the PAQ's theoretical basis (N-DIF, P-DIF, N-DDF, P-DDF, G-EOT), with all items loading well on their intended ASSESSING ALEXITHYMIA IN ADOLESCENTS subscale factor.…”

“…In terms of concurrent validity, PAQ scores have correlated highly with TAS-20 scores (with the PAQ so far demonstrating higher EOT reliability when directly compared to the TAS-20 within the same samples; see Bilge & Bilge, 2020;Chan et al, in press;Greene et al, 2020a;Preece et al, 2020b), and other established measures of emotion regulation difficulties and psychopathology symptoms. For example, high PAQ scores have been associated with severe depression and symptoms of anxiety (Bilge & Bilge, 2020;Preece et al, 2018aPreece et al, , 2022, borderline personality disorder (Mousavi Asl et al, 2020), non-suicidal self-injury (Greene et al, 2020a(Greene et al, , 2020b, and with increased usage of maladaptive emotion regulation strategies (e.g. Preece et al, 2018a).…”

Disordered eating: The psychometric properties of the Persian version of the Eating Attitudes Test-8

“…Assessment of psychometric properties of this scale in societies with various cultures can help external validity. [ 30 ] In the present study, we present a new questionnaire developed to provide an tool that is brief enough to be applied in epidemiological screenings and that assessing the frequency and the intensity of disordered eating attitudes and behaviors. In addition, due to prevalence and outcomes of eating disorders and lack of a valid and reliable scale to assess problematic eating in Persian language and its importance in clinical research and treatment, the current study aimed to investigate psychometric properties Persian version of EAT-8.…”
