ABSTRACT

The aim of this study was to validate the Turkish version of the ABQOL and TABQOL questionnaires and to assess the reliability of them in the Turkish population.

The Turkish versions of the ABQOL and TABQOL questionnaires were produced by forward–backward translation of the original English version. The patients were requested to complete ABQOL and TABQOL questionnaires on day 0 and after 7 days for a 2nd time sent by post. Furthermore, patients also completed other health‑related quality of life scales on day 0.

A total of 68 patients with AIBDs were recruited. A subset of 20 (29.4%) patients completed the day 7 questionnaire. Both the Turkish versions of the ABQOL and TABQOL questionnaires had a high internal consistency (0.86 and 0.88, respectively) and test– retest reliability (0.87 and 0.87, respectively). The correlation between ABQOL and TABQOL scores was moderate (Pearson’s R = 0.609).

We have shown that the Turkish versions of ABQOL and TABQOL questionnaires are valid and reliable instruments. They can be used to measure treatment burden in Turkish AIBD patients.
