Abstract

The aim of this study was to translate and culturally validate the Psoriatic Arthritis Quality of Life Questionnaire (PsAQoL) into Turkish and to evaluate its reliability and validity in patients with psoriatic arthritis (PsA). A total of 162 PsA patients diagnosed according to CASPAR criteria were recruited from two rheumatology clinics. The PsAQoL was translated and culturally adapted into Turkish using a standardized forward-backward translation method. Internal consistency was assessed using Cronbach's alpha. Construct validity was evaluated by correlating PsAQoL scores with quality of life (SF-36), functional (HAQ), emotional (HADS), and clinical disease activity indices (DAPSA, BASDAI, DAS28). The Turkish version of the PsAQoL was found to be clear, concise, and well understood by patients. The average time to complete the questionnaire was 3.3 ± 0.9 min. Internal consistency was good (Cronbach's α = 0.930). Strong correlations were found with SF-36 physical (r = - 0.744) and mental components (r = - 0.731), indicating convergent validity. Moderate correlations were observed with HAQ (r = 0.533), VAS pain (r = 0.408), HADS-Anxiety (r = 0.535), and HADS-Depression (r = 0.517), while correlations with unrelated clinical parameters such as age and PASI were weak or insignificant, indicating divergent validity. No floor or ceiling effects were detected, and there were no missing responses. The Turkish version of the PsAQoL is a valid, reliable, and practical tool for assessing disease-specific quality of life in PsA. Its ease of use and psychometric strength support its application in both clinical practice and researchs.

土耳其人群银屑病关节炎生活质量（PSAQoL）问卷的有效性和心理测量学特征。

本研究的目的是将银屑病关节炎生活质量问卷（PsAQoL）翻译成土耳其语并进行文化验证，并评估其在银屑病关节炎（PsA）患者中的信度和效度。根据CASPAR标准诊断的162例PsA患者从两个风湿病诊所招募。PsAQoL的翻译和文化适应成土耳其语使用标准化的前向后翻译方法。内部一致性采用Cronbach’s alpha评价。通过PsAQoL评分与生活质量（SF-36）、功能（HAQ）、情绪（HADS）和临床疾病活动指数（DAPSA、BASDAI、DAS28）的相关性来评估结构效度。发现土耳其语版本的PsAQoL清晰，简洁，并且患者很好地理解。问卷平均完成时间为3.3±0.9 min，内部一致性较好（Cronbach’s α = 0.930）。SF-36物理成分（r = - 0.744）和心理成分（r = - 0.731）存在强相关性，表明趋同效度。与HAQ （r = 0.533）、VAS疼痛（r = 0.408）、hads -焦虑（r = 0.535）、hads -抑郁（r = 0.517）存在中度相关性，而与年龄、PASI等不相关的临床参数相关性较弱或不显著，存在差异效度。没有检测到地板或天花板效应，也没有缺失反应。土耳其版PsAQoL是评估PsA疾病特异性生活质量的有效、可靠和实用的工具。它的易用性和心理测量强度支持其在临床实践和研究中的应用。

期刊介绍： RHEUMATOLOGY INTERNATIONAL is an independent journal reflecting world-wide progress in the research, diagnosis and treatment of the various rheumatic diseases. It is designed to serve researchers and clinicians in the field of rheumatology. RHEUMATOLOGY INTERNATIONAL will cover all modern trends in clinical research as well as in the management of rheumatic diseases. Special emphasis will be given to public health issues related to rheumatic diseases, applying rheumatology research to clinical practice, epidemiology of rheumatic diseases, diagnostic tests for rheumatic diseases, patient reported outcomes (PROs) in rheumatology and evidence on education of rheumatology. Contributions to these topics will appear in the form of original publications, short communications, editorials, and reviews. "Letters to the editor" will be welcome as an enhancement to discussion. Basic science research, including in vitro or animal studies, is discouraged to submit, as we will only review studies on humans with an epidemological or clinical perspective. Case reports without a proper review of the literatura (Case-based Reviews) will not be published. Every effort will be made to ensure speed of publication while maintaining a high standard of contents and production. Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
