BACKGROUND: Disordered eating attitude may lead to full‑blown eating disorders. Recentlongitudinal studies show that disordered eating attitudes either remain stable or even increase fromchildhood to adulthood. The current study was done to determine the psychometric properties of theEating Attitudes Test‑8 (EAT‑8) and introduce the suitable measure for researchers and therapist inthe field of clinical psychology and psychiatrist.MATERIALS AND METHODS: The Persian version of the EAT‑8 was produced through forwardtranslation, reconciliation, and back translation. A sample of 302 students were selected throughconvenience 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 usingconfirmatory factor analysis and divergent and convergent validity. Internal consistency and test–retestreliability (2 weeks’ interval) were conducted to evaluate the reliability. Data analysis was conductedusing SPSS (version 22) software and LISREL (version 8.8).RESULTS: EAT‑8 was found to be valid and reliable measures, with good internal consistency andgood test–retest reliability among students. In terms of convergent validity, EAT‑8 showed a significantpositive correlation with self‑report measures of EAT‑16 and EBQ‑18. EAT‑8 showed a negativecorrelation with self‑compassion and self‑esteem, thus demonstrated a good divergent validity. Theresults 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 assessingdisordered eating in Iranian population. The EAT‑8 shows notable promise as a measure for use indisordered eating research and clinical settings.
