This research evaluates the psychometric properties of an Arabic translation of the Body Appreciation Scale (BAS-2) and two shortened versions, comprising three items and two items, among 826 Lebanese community adults. Participants completed an online survey that included the translated scales, the functionality appreciation scale, and the Eating Attitudes Test-26. Analysis demonstrated that the full ten-item scale and both short forms converged on a single-factor structure with high internal consistency. The measures proved invariant across gender at configural, metric, and scalar levels. Scores across all forms showed strong positive correlations with healthier eating attitudes and greater functionality appreciation, while the full scale also had a weak positive correlation with body mass index. Both shortened forms correlated very strongly with the full ten-item version, confirming their validity.
Validating psychological assessment tools in different languages ensures that clinicians and researchers can accurately measure body image and related behaviours across diverse cultural populations. Having reliable full-length and brief instruments enables more flexible, effective screening for positive body image, which is vital for studying and treating eating-related conditions.
The validated scales provide tested, ready-to-use assessment instruments for clinical practitioners, psychological service providers, and researchers working with Arabic-speaking populations. The brief two-item and three-item versions are applied and tested, making them especially suitable for integration into digital health platforms, intake questionnaires, or broad population surveys where assessment time is restricted.

OBJECTIVES: The present study sought to examine the factor structure, reliability, validity and gender invariance of the Arabic Body Appreciation Scale (BAS-2), and its two short forms (the 3-item and 2-item BAS-2SF) among community Lebanese Arabic-speaking adults. METHODS: We carried-out an online cross-sectional survey. The 10-item BAS-2, the functionality appreciation scale and the Eating Attitudes Test-26 were completed by 826 Lebanese community adults (57.9% females, aged 25.42 ± 8.44 years). RESULTS: The Arabic 10-item, 3-item and 2-item BAS-2 converged on a one-factor solution, and demonstrated high internal consistency (McDonald's ω value of .92, .88, and .86 respectively). All indices suggested that configural, metric, and scalar invariance was supported across gender. The 3-item and 2-item BAS-2SF were highly correlated with the original BAS-2 (r > 0.9). Higher 10-item, 3-item and 2-item BAS-2 scores correlated significantly and strongly with more positive eating attitudes and greater functionality appreciation, and higher 10-item BAS-2 scores correlated positively and weakly with BMI, supporting convergent validity. CONCLUSION: The present work contributes to the literature by providing a psychometrically sound Arabic-translation of the BAS-2 and short-forms, benefitting both researchers and clinicians.
