背景：在决定和评估诊断为肛瘘的患者的治疗策略时，通常会考虑生活质量。目的：本研究的目的是开发和心理测量测试肛瘘患者的生活质量问卷。设计：这是一项用于开发和验证心理测量工具的观察性横断面研究。背景：该研究在西班牙东南部的一家综合医院进行。患者：方便样本包括 54 名诊断为肛瘘的患者。主要结果指标：该工具的可靠性通过其内部一致性（Cronbach alpha）和时间稳定性（重测之间的斯皮尔曼相关系数（r））进行评估。计算项目和量表的内容效度指数。所开发的工具与 Short Form 12 健康调查之间的相关性分析和序数回归分析检查了其同时有效性。使用 Kruskal-Wallis 检验的主成分分析和已知群体分析检查了其结构有效性。结果：所开发的问卷的可靠性非常高（α = 0.908；r = 0.861；p < 0.01）。其内容效度非常好（所有项目内容效度指数 = 0.79-1.00；量表效度指数 = 0.92）。其同时有效性的证据包括所开发的工具与简表 12 健康调查之间的强相关性 (r = 0.734；p < 0.001)，并且所开发工具的参与者分数解释了简表 12 健康调查参与者分数的受试者间差异的大约 46.2% (Nagelkerke R-2 = 0.462)。主成分分析证实了其结构有效性，显示 2 个因素解释了所发现的总方差的 81.63%。已知组分析证明了问卷能够检测具有不同症状的患者的预期差异。 局限性：本研究的主要局限性是使用了小样本西班牙语患者，不包括问卷最初制定的患者，并使用求和法开发评分系统。结论：肛瘘患者生活质量问卷已被证明是一种有效、可靠和简洁的工具，有助于评估肛瘘患者的生活质量。肛瘘患者的生活。请参阅视频摘要：http://links.lww.com/DCR/A368。
BACKGROUND: Quality of life is often considered when deciding and evaluating the treatment strategy for patients diagnosed with anal fistula.OBJECTIVE: The purpose of this study was to develop and psychometrically test the Quality of Life in Patients with Anal Fistula Questionnaire.DESIGN: This was an observational cross-sectional study for the development and validation of a psychometric tool.SETTINGS: The study was conducted at a general hospital in the southeast of Spain.PATIENTS: A convenience sample included 54 patients diagnosed with anal fistula.MAIN OUTCOMES MEASURES: The reliability of the tool was assessed through its internal consistency (Cronbach alpha) and temporal stability (Spearman correlation coefficient (r) between test-retest). The content validity index of the items and the scale was calculated. Correlation analysis and an ordinal regression analysis between the developed tool and the Short Form 12 Health Survey examined its concurrent validity. Principal component analysis and known-group analysis using the Kruskal-Wallis test examined its construct validity.RESULTS: The reliability of the developed questionnaire was very high (alpha = 0.908; r = 0.861; p < 0.01). Its content validity was excellent (all-item content validity index = 0.79-1.00; scale validity index = 0.92). Evidence of its concurrent validity included strong correlation between the developed tool and Short Form 12 Health Survey (r = 0.734; p < 0.001), and participant scores on the developed tool explained approximate to 46.2% of the between-subject variation for the participant scores on Short Form 12 Health Survey (Nagelkerke R-2 = 0.462). Confirming its construct validity, principal component analysis revealed that 2 factors explained 81.63% of the total variance found. Known-group analysis evidenced the ability of the questionnaire to detect expected differences in patients presenting with different symptomatology.LIMITATIONS: The major limitations of this study were the use of a small sample of Spanish-speaking patients, not including patients in the initial development of the questionnaire, and developing the scoring system using a summation method.CONCLUSIONS: The Quality of Life in Patients with Anal Fistula Questionnaire has proven to be a valid, reliable, and concise tool that could contribute to the evaluation of quality of life among patients with an anal fistula.
