Experiential avoidance is one of the most frequently emphasized transdiagnostic constructs in the literature and has been receiving increasing attention in both research and clinical practice. The aim of this study was to examine the psychometric properties of the Turkish version of the Brief Experiential Avoidance Questionnaire (BEAQ), a scale designed to provide a concise assessment of experiential avoidance. The study was conducted with 356 voluntary participants aged 18 to 64. The validity of the BEAQ was examined using factor analyses and correlation-based methods, and its reliability was assessed through internal consistency. Construct validity was assessed through exploratory structural equation modeling (ESEM), which combines exploratory and confirmatory methods. In addition, a Graded Response Model (GRM) analysis was conducted to evaluate item discrimination. For validity, associations with measures of avoidance, psychological symptoms (anxiety and depression), and negative affect were examined. ESEM results confirmed the original single-factor structure. The BEAQ demonstrated high internal consistency (α = .889; ω = .892). The GRM analysis revealed that the items demonstrated adequate levels of discrimination. The BEAQ demonstrated strong associations with avoidance-related measures, moderate relationships with psychological symptoms, and weaker links with negative affect, supporting its specificity to experiential avoidance. The findings supported the validity and reliability of the Turkish version of the BEAQ as a measure of experiential avoidance and were discussed in the context of the literature and future research.
