This cross-sectional methodological study evaluated the psychometric properties and external validity of the Turkish adaptation (BİL-YE) of the Mind-Eat Scale in 300 adults aged 19–64 years, using confirmatory factor analysis (CFA), internal consistency, test–retest reliability (n=150, 2-week interval), and concurrent validity against the TFEQ-R18 and anthropometric measurements.
CFA confirmed the original six-factor structure (hunger/satiety, non-judgment, openness, awareness, gratitude, non-reactivity) with acceptable fit (χ²/df=1.51, CFI=0.94, TLI=0.93, RMSEA=0.041). Subscale Cronbach's alpha ranged from 0.52–0.88, and test–retest ICCs ranged from 0.63–0.92; the total-scale ICC was 0.75. Non-judgment and non-reactivity were inversely associated with TFEQ-R18 subscales, and several facets showed small positive associations with BMI and waist/hip circumference.
- Cross-sectional design limits causal inference between mindful eating facets and adiposity measures. - Overall scale internal consistency was modest (Cronbach's α=0.64, McDonald's ω=0.53), and two subscales had alpha/omega as low as 0.52, suggesting limited reliability at the facet level. - The study is not preregistered, raising potential for selective reporting.
The Turkish BİL-YE is a psychometrically acceptable tool for measuring multidimensional mindful eating in adult clinical and research settings. Clinicians and researchers working with Turkish-speaking populations can use it to assess eating behavior facets relevant to obesity-related outcomes, though subscale-level scores should be interpreted cautiously given variable internal consistency.
