DOI : 10.5606/tftrd.2020.4013 Objectives: The aim of this study was to adapt the Assessment of Knowledge in Ankylosing Spondylitis Patients by a Self-Administered Questionnaire for the Turkish ankylosing spondylitis (AS) patients.

Patients and methods: Between May 2016 and December 2016, a total of 100 AS patients (72 males, 28 females; mean age 43.4 years; range, 21 to 73 years) were included in the study. A forward (into Turkish) and backward translation of the questionnaire was performed. Reliability was evaluated using the Cronbach alpha (α) value, test-retest reliability, and intra-class correlations (ICCs). The correlations with demographic data including age, sex, time since diagnosis, and education status and with the disease-specific assessments including Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and the Ankylosing Spondylitis Quality of Life (ASQOL) questionnaire were investigated.

Results: The Turkish version of the questionnaire showed a good reliability (Cronbach-α: >0.70, ICC: >0.90). A significant correlation was found with the education status (p<0.001). However, no significant correlation was observed between the questionnaire and the other parameters (p>0.05).

Conclusion: Our study results show that the Turkish version of the questionnaire seems to be reliable for use in Turkish AS patients. Keywords : Ankylosing spondylitis, awareness, knowledge, reliability
