Abstract / Summary
Abstract Aim This study aimed to adapt the Body Acceptance Scale for Women with Breast Cancer (BAS-BC) into Turkish and evaluate its psychometric properties among Turkish women who had undergone surgery for breast cancer. Methods This methodological and cross-sectional study was conducted between April 2024 and May 2025 in the Department of General Surgery of a hospital. The sample consisted of 136 women who had undergone surgical treatment for breast cancer. Linguistic validity, content validity, construct validity, and reliability were assessed. Construct validity was evaluated using exploratory and confirmatory factor analyses. Internal consistency was examined using Cronbach’s alpha, composite reliability (CR) was calculated as a reliability indicator, and average variance extracted (AVE) was calculated to assess convergent validity. Results Exploratory factor analysis revealed a modified five-factor structure that retained all 17 items of the original six-factor BAS-BC explaining 78.97% of the total variance. In the Turkish version, the original “Encounter” and “Adaptation” subdimensions merged into a single factor named “Encounter and Adaptation to the Body.” Confirmatory factor analysis showed mixed model fit indices: chi-square/degrees of freedom ratio (χ²/df) = 2.69, root mean square error of approximation (RMSEA) = 0.112, comparative fit index (CFI) = 0.91, and Tucker–Lewis index (TLI) = 0.89. Therefore, the confirmatory findings were interpreted cautiously. Cronbach’s alpha coefficients ranged from 0.71 to 0.92, and the overall internal consistency coefficient was 0.897. Composite reliability values exceeded 0.70 for all subdimensions, whereas average variance extracted values exceeded 0.50 for four of the five subdimensions. Conclusions The Turkish version of the Body Acceptance Scale for Women with Breast Cancer demonstrated acceptable preliminary psychometric properties while retaining all 17 items and exhibiting a modified five-factor structure compared with the original six-factor structure. However, because exploratory and confirmatory factor analyses were conducted in the same sample and the RMSEA value indicated suboptimal fit, further validation in larger and independent samples is recommended.
