This study was planned to investigate the validity, reliability and responsıveness of the "Bilişsel Egzersiz Terapi Yaklaşımı" (BETY-Cognitive Exercise Therapy Approach) Scale in patients with ankylosing spondylitis (AS). 157 patients diagnosed with ankylosing spondylitis were included in the study. Scales frequently used in AS were selected to investigate the validity of the BETY scale. Functionality, quality of life and mood parameters were examined with these scales. The scales used were Health Assessment Questionnaire for Spondyloarthropathies (HAQ-S), Short Form 36 (SF-36), Ankylosing Spondylitis Quality of Life Questionnaire (ASQoL), Hospital Anxiety and Depression Scale (HADS), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI) were used for validity of the BETY Scale. The correlation of BETY scale with other scales was found between r=-0,519 and 0,819, p<0,001. The test-retest method and intraclass correlation coefficient (ICC) were used for reliability. The correlation between the responses of 34 patients to the BETY scale for 1 week (r = 0.864, p <0.001) and ICC (0.944, p <0.001) were significantly high. The Cronbach alpha coefficient (0.936) was also used for internal consistency which was very high. For the responsiveness of the scale, the correlation of the differences of the BETY Scale with all scales was checked after 3 months in 48 patients with AS. While a high degree of correlation was found with ASQoL (r = 0.672, p <0.001) which is specific to AS, moderate and low correlation was found with other scales. As a result of our study, it was concluded that the BETY Scale is a valid, reliable and responsive assessment tool for AS patients.
