Abstract

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).ConclusionOur study results show that the Turkish version of the questionnaire seems to be reliable for use in Turkish AS patients.
