This study aims to examine the reliability and validity of the Turkish version of Body Attitude Test among women with breast cancer. The study included 101 voluntary women with breast cancer stage 1, 2 or 3 from different regions of Turkey. The Turkish versions of Body Attitude Test, Body Shape Questionnaire and Eating Attitudes Test were applied twice with a 7- day interval. The test demonstrated high test-retest reliability (Intra-class Correlation Coefficient = 0.95) with a good internal consistency (Cronbach's alpha = 0.82; McDonald's omega = 0.89) for all domains. The confirmatory factor analysis resulted in 4 factor structures and at an acceptable good fit-in with x(2)/df for BAT. The Body Attitude Test correlated strongly with the Body Shape Questionnaire and Eating Attitudes Test (p < 0.05). The results support the Turkish version of the test is a valid and reliable instrument that can be used to measure the body attitude of women with breast cancer. This test can be used as an appropriate measurement tool in assessing the subjective attitude towards the body in women with breast cancer.
