This study aims to translate the Evaluation of Ankylosing Spondylitis Quality of Life (EASi-QoL) into the Turkish language and test its validity and reliability.
A total of 100 AS patients (74 males; 26 females; mean age 38.2±9.9 years; range 21 to 63 years) were included. The mean disease duration was 115.9±91.6 months. EASi-QoL was translated from English into Turkish, and synthesis, back translation, revision, and pretest stages were performed. All patients were asked to complete the Turkish version of EASi-QoL. The internal consistency of EASi-QoL was determined with Cronbach's alpha coefficient, and test-retest reliability was assessed by calculating the intra-class correlation coefficient. Confirmatory and explanatory factor analyses were performed to assess structural validity. Construct validity was also investigated by comparing the results of EASi-QoL with the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Metrology Index (BASMI), Ankylosing Spondylitis Disease Activity Score, Maastricht Ankylosing Spondylitis Enthesitis Score (MASES), and AS-specific QoL scale.
Cronbach's alpha coefficient was 0.910 in the physical function category, 0.893 in the disease activity category, 0.935 in the emotional well- being category, and 0.930 in the social contribution category (α>0.7). Factor loadings of all items in EASi-QoL were higher than 0.7, indicating the high reliability of the questionnaire. There was also a strong positive correlation between all subcategories of EASi-QoL (physical function, disease activity, emotional well-being and social participation) and AS-specific QoL scale, BASDAI, Bath BASFI, patient's global assessment and pain severity. MASES and BASMI showed a moderate correlation with emotional well-being and social participation categories of EASi-QoL.
Turkish version of EASi-QoL is a reliable and valid scale that can be used in clinical practice to evaluate QoL in detail in patients with AS.
本研究旨在将强直性脊柱炎生活质量评估量表（EASi-QoL）翻译成土耳其语，并测试其有效性和可靠性。
共纳入100例强直性脊柱炎患者（男性74例；女性26例；平均年龄38.2±9.9岁；年龄范围21至63岁）。平均病程为115.9±91.6个月。EASi-QoL从英语翻译成土耳其语，并进行了综合、回译、修订和预测试阶段。所有患者均被要求完成土耳其语版的EASi-QoL。用Cronbach's α系数确定EASi-QoL的内部一致性，并通过计算组内相关系数评估重测信度。进行验证性和解释性因子分析以评估结构效度。还通过比较EASi-QoL与巴斯强直性脊柱炎疾病活动指数（BASDAI）、巴斯强直性脊柱炎功能指数（BASFI）、巴斯强直性脊柱炎计量指数（BASMI）、强直性脊柱炎疾病活动评分、马斯特里赫特强直性脊柱炎附着点炎评分（MASES）以及强直性脊柱炎特异性生活质量量表的结果来研究构想效度。
身体功能类别中Cronbach's α系数为0.910，疾病活动类别中为0.893，情感幸福类别中为0.935，社会贡献类别中为0.930（α>0.7）。EASi-QoL中所有条目的因子载荷均高于0.7，表明问卷具有较高的可靠性。EASi-QoL的所有子类别（身体功能、疾病活动、情感幸福和社会参与）与强直性脊柱炎特异性生活质量量表、BASDAI、巴斯BASFI、患者整体评估和疼痛严重程度之间也存在很强的正相关。MASES和BASMI与EASi-QoL的情感幸福和社会参与类别呈中度相关。
土耳其语版的EASi-QoL是一个可靠且有效的量表，可用于临床实践中详细评估强直性脊柱炎患者的生活质量。
