Individuals diagnosed with schizophrenia have a two to five-fold higher risk of developing obesity and up threefold disordered eating behaviors relative the general population. Over past decades, Eating Attitude Test (EAT) has been well-recognized widely used in clinical practice. However, only little psychometric information is available on EAT for researchers clinicians who deal patients schizophrenia, it still unclear whether scale could fulfill measurement needs help research decision-making context psychotic disorders. This study aimed investigate properties shortest version (EAT-7) among newly-diagnosed had minimal exposure antipsychotics at start study. an observational, cross-sectional survey that was carried out department psychiatry Razi Hospital, Manouba, Tunisia. The took place between January June 2024, involved clinically-stabilized outpatients < 3 months treatment (N = 112; mean age 24.44 ± 5.41 years). In terms factor analysis, EAT-7 presented one-dimensional structure. All seven items strongly loaded single factor, all indices CFA suggesting good fit data. addition, yielded excellent reliability coefficients, both McDonald's ω Cronbach's α 0.88. Measurement invariance across sex groups tested using multi-group CFA, established configural, scalar, metric levels. No significant differences scores males females were found. Finally, positively correlated depression anxiety, supporting concurrent validity scale. shortness, items' clarity conciseness make efficient tool appropriate as first-step screening detect low cost burden. We hope this will facilitate widespread application routine assessment monitoring practices.

Background The factorial structure of the Eating Attitudes Test (EAT-26) has been found inconsistent across studies and samples. This study examined measurement invariance Arabic version EAT-26 in a large non-clinical Saudi sample. Methods 1,734 adults (M_age 26.88 SD 9.13), predominantly female, completed an online survey. Confirmatory factor analysis evaluated several established models to identify best-fitting model for EAT-26. Results original three-factor two other common demonstrated poor fit. Instead, 16-item, four-factor [(Self-Perceptions Body Weight), (Dieting), (Awareness Food Contents), (Food Preoccupation)] showed acceptable fit ([CFI = 0.904; SRMR 0.0554; RMSEA 0.073 [90% CI: 0.068–0.077]). Internal consistency was good, supported sex BMI categories. Conclusions These findings suggest need culturally relevant validation among Arabic-speaking populations, as differed from previous models. Future research should further examine this revised clinical settings.

Abstract Background The factorial structure of the Eating Attitudes Test (EAT-26) has been found to be inconsistent across studies and samples. This study aimed resolve inconsistencies in Arabic version EAT-26 by identifying best-fitting model test its measurement invariance sexes BMI categories a large non-clinical Saudi sample. Methods 1,734 adults ( M age 26.88 SD 9.13), predominantly female, completed an online survey. Several existing models were tested (e.g., original 26-item three-factor model, second order 20-item four-factor 16-item model) using confirmatory factor analysis (CFA). Fit indices including CFI, SRMR, RMSEA used identify for EAT-26. Multi-group (MGCFA) was invariance. Results two other common demonstrated poor fit CFI = 0.727; SRMR 0.0911; 0.085 [90% CI 0.082–0.087] model). Instead, 16-item, [(Self-Perceptions Body Weight), (Dieting), (Awareness Food Contents), (Food Preoccupation)] showed acceptable ([CFI 0.904; 0.0554; 0.073 0.068- 0.077]). Internal consistency good (α ω 0.88), supported sex (male female) (underweight, normal weight, overweight, obese). Conclusions These findings underscore need culturally relevant validation among Arabic-speaking populations, as revised diverged from previously established models. Future research should further examine this clinical settings.
