Abstract :Falls are common in individuals with lower extremity amputations, often leading to physical injuries and fear of falling. This fear can reduce daily activity, social participation, and quality of life. Therefore, balance assessment should consider not only physical performance but also psychological factors, motivation, and confidence, which influence balance and prosthesis use. The Activity-Specific Balance Confidence (ABC) Scale is a 16-item self-efficacy measure designed to assess fear of falling. To evaluate the validity and reliability of the Turkish translation of the ABC scale in a lower limb amputee population. The ABC scale was administered to 80 individuals with limb loss twice, with a one week interval between tests. Confirmatory Factor Analysis was performed to asses construct validity The Cronbach\\\'s alpha coefficient was calculated to analyze internal consistency. Spearman’s correlation coefficient were calculated to determine test–retest reliability. Confirmatory factor analysis confirmed that the Turkish version of the ABC Scale has a single-factor structure. The Spearman’s correlation coefficient (ICC) for the Turkish version was 0.93, indicating high test–retest reliability. Cronbach’s α was 0.937, split-half reliability was 0.943, and McDonald’s ω was 0.90. These findings indicate excellent internal consistency of the scale. The Turkish version of the ABC scale is a valid and reliable tool for assessing balance confidence in lower limb amputees using prostheses.
