ABSTRACT
BACKGROUND: Impulsiveness is a multidimensional and multifaceted construct that plays an important role in understanding various psychopathology and problematic behavior. It is necessary to study the psychometric properties of instruments in the new culture before its scientific application, and it also contributes to external validity. The current study was conducted to determine the psychometric properties of the Persian version of Short Form of the Impulsiveness Questionnaire UPPS-P (SUPPS-P) in a sample of male soldiers serving in the military service. MATERIALS AND METHODS: The present research design is cross-sectional in 2019-2020. The Iranian version of the SUPPS-P was prepared across forwarding translation, reconciliation, and back-translation. The research sample included 254 soldiers who were selected via convenience sampling method and completed a set of scales, including the SUPPS-P scales, short-form self-compassion scale, McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD), Cognitive Flexibility Inventory (CFI), Perth Alexithymia Questionnaire (PAQ), and the Deliberate Self-harm Inventory (DSHI). The construct validity of SUPPS-P scale was measured using confirmatory factor analysis and convergent and divergent validity. For reliability, Cronbach's alpha and test-retest reliability (with 2 weeks interval) were used. Data were analyzed using LISREL software (version 8.8) and SPSS version 22. RESULTS: The results showed that the SUPPS-P scale is a reliable and valid scale with acceptable internal consistency and acceptable test-retest reliability among soldiers. In terms of convergent validity, SUPPS-P showed a significant positive correlation with measures of MSI-BPD, PERS, and DSHI. SUPPS-P showed a negative correlation with self-compassion and cognitive flexibility, thus demonstrated a good divergent validity. The results of this study also provide support for the five-factor model of the SUPPS-P scale. CONCLUSION: The SUPPS-P instrument showed acceptable validity and reliability and could be useful in assessing impulsivity in Iranian society. The SUPPS-P scale shows notable promise as a measure for use in impulsivity research and clinical settings.
ABSTRACT
Background: Perfectionism is a key construct for understanding psychopathology. In societies with varying cultures, studying the psychometric properties of tools can help with their external validity. This research aimed at standardization and validation of the Eating Disorder Inventory-Perfectionism (EDI-P) scale in Iran. Methods: The Persian version of EDI-P was formed through forward translation, reconciliation, and back translation. A total of 302 students were selected using convenience sampling method and' they completed a set of questionnaires, including the EDI-P, 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 EDI-P was assessed using confirmatory factor analysis and divergent and convergent validity. Internal consistency and test-retest reliability (2 weeks' interval) were applied to evaluate reliability. LISREL (version 8.8) and SSPS (version 22) software were used for data analysis purpose. Results: EDI-P scales and subscales were found to be a valid and reliable measure, with good internal consistency and good test-retest reliability in the nonclinical sample. Cronbach's alpha coefficient for the whole scale, socially prescribed, and self-oriented were found to be 0.74, 0.68, and 0.67, respectively. Test-retest reliability for the whole scale, socially prescribed, and self-oriented were found to be 0.88, 0.80, and 0.87, respectively. Convergent validity and divergent validity were good (Normed Fit Index [NFI] = 0.94, Incremental Fit Index = 0.95, root mean square error of approximation = 0.08, goodness of fit index = 0.97, Non-normed Fit Index [NNFI] = 0.91, and comparative fit index = 0.95). The results of this study provide support for the two-factor model of EDI-P. Conclusion: The EDI-P showed good validity and reliability and could be useful in assessing perfectionism in Iranian population. The EDI-P shows notable promise as a measure for use in eating research and clinical settings.
ABSTRACT
BACKGROUND: Screening for eating disorders via reliable instruments is of high importance for clinical and preventive purposes. Examining the psychometric properties of tools in societies with differing dynamics can help with their external validity. This research specifically aimed at standardization and validation of the eating attitude test (EAT-16) in Iran. METHODS: The Persian version of the EAT-16 was produced through forward translation, reconciliation, and back translation. The current research design was descriptive cross-sectional (factor analysis). A total of 302 nonclinical students were selected through the convenience sampling method and completed a set of questionnaires. The questionnaires included, the EAT-16, eating beliefs questionnaire-18 (EBQ-18), difficulties in emotion regulation scale-16 (DERS-16), weight efficacy lifestyle questionnaire-short form, self-esteem scale, and self-compassion scale short-form. The construct validity of the EAT-16 was assessed using confirmatory factor analysis and divergent and convergent validity. Internal consistency and test-retest reliability (2 weeks' interval) were used to evaluate the reliability. Data analysis was conducted using LISREL (version 8.8) and SSPS (version 22) software. RESULTS: EAT-16 and subscales were found to be valid and reliable, with good internal consistency and good, test-retest reliability in a non-clinical sample. In terms of convergent validity, EAT-16 and subscales showed a positive correlation with the selfreport measures of EBQ-18 and DERS-16. EAT-16 and subscales showed a negative correlation with self-compassion, self-esteem and eating self-efficacy., Therefore, it demonstrated divergent validity with these constructs. The results of this study support the EAT-16 four-factor model. CONCLUSIONS: The EAT-16 showed good validity and reliability and could be useful in assessing eating disorders in Iranian populations. The EAT-16 is an efficient instrument that is suitable for screening purposes in the nonclinical samples.
ABSTRACT
BACKGROUND: The coronavirus has caused fundamental changes in our way of life, leading to a wave of psychological distress associated with the COVID-19 epidemic, including stress, anxiety, perceived threats, and fear. Considering the psychological consequences of COVID-19, the present study was conducted with the aim of mediating the role of compassion in the relationship between COVID-19 anxiety syndrome and COVID-19 burnout. MATERIALS AND METHODS: The design of the present study was descriptive correlation. The present study population included all students of Ahvaz Jundishapur University of Medical Sciences in the academic year 2020. Two hundred and fifty-one students were selected and completed the COVID-19 Anxiety Syndrome Questionnaire, Compassion Scale, and COVID-19 Burnout Scale. Pearson correlation coefficient test and structural equation model were performed using SPSS version 18 and LISREL 8.8. RESULTS: The results showed that COVID-19 burnout had a positive and significant relationship with the overall score of anxiety syndrome (r = 0.42, P = 0.01), while it has a negative and significant relationship with compassion (r = -0.37, P = 0.01). Compassion also has a significant negative relationship with anxiety syndrome (r = -0.35, P = 0.01). In addition, the results of path analysis showed that compassion plays a mediating role in the relationship between COVID-19 anxiety syndrome and COVID-19 burnout. CONCLUSION: Based on the findings of the present study, it can be said that compassion acts as a protective factor against the negative effects of anxiety syndrome. Therefore, this factor can be considered in the development of prevention and treatment programs for burnout caused by COVID-19.
ABSTRACT
BACKGROUND: Disordered eating attitude may lead to full-blown eating disorders. Recent longitudinal studies show that disordered eating attitudes either remain stable or even increase from childhood to adulthood. The current study was done to determine the psychometric properties of the Eating Attitudes Test-8 (EAT-8) and introduce the suitable measure for researchers and therapist in the field of clinical psychology and psychiatrist. MATERIALS AND METHODS: The Persian version of the EAT-8 was produced through forward translation, reconciliation, and back translation. A sample of 302 students were selected through convenience sampling method and completed a set of questionnaires, including the EAT-8, Eating Attitudes Test-16 (EAT-16), Eating Beliefs Questionnaire-18 (EBQ-18), self-esteem scale, and self-compassion scale short-form. The construct validity of the EAT-8 was assessed using confirmatory factor analysis and divergent and convergent validity. Internal consistency and test-retest reliability (2 weeks' interval) were conducted to evaluate the reliability. Data analysis was conducted using SPSS (version 22) software and LISREL (version 8.8). RESULTS: EAT-8 was found to be valid and reliable measures, with good internal consistency and good test-retest reliability among students. In terms of convergent validity, EAT-8 showed a significant positive correlation with self-report measures of EAT-16 and EBQ-18. EAT-8 showed a negative correlation with self-compassion and self-esteem, thus demonstrated a good divergent validity. The results of this study also provide support for the one-factor model of the EAT-8. CONCLUSION: The EAT-8 showed good validity and reliability and could be useful in assessing disordered eating in Iranian population. The EAT-8 shows notable promise as a measure for use in disordered eating research and clinical settings.
