目的 :编制适合我国文化背景的腹膜透析生活质量量表。方法 :通过文献检索及患者访谈分别构建量表条目池;应用Delphi专家咨询法、条目分析、变异系数、条目间相关系数、条目与维度间相关系数、内部一致性系数、因子分析等对量表条目进行筛选,并进行信效度检验。结果 :量表一周后重测信度为0.781;Cronbach’sα系数为0.936,显示量表具备较好的信度。与SF-36做效标关联度时,两量表总分的相关系数为0.956。对量表结构效度考评时,通过主成分因子分析提取了10个公因子,公因子的分布与维度间的联系符合前期理论构想及预期结果。结论 :形成的腹膜透析患者生活质量量表有较好的信效度,可在我国腹膜透析患者生活质量的测评中推广应用。
Objective: To prepare peritoneal dialysis quality of life scale suitable for our country’s cultural background. Methods: A pool of scale items was constructed through literature search and patient interviews. Delphi questionnaire was used to analyze the relationship between scale, item analysis, coefficient of variation, correlation coefficient between items, correlation coefficient between items and dimensions, internal consistency coefficient and factor analysis Entries were screened and tested for reliability. Results: The test-retest reliability after one week was 0.781; the coefficient of Cronbach’s α was 0.936, which showed that the scale had good reliability. And SF-36 as the standard correlation degree, the correlation between the two scales total score of 0.956. When evaluating the validity of the scale structure, 10 common factors were extracted from the principal component factor analysis. The distribution of the common factors was consistent with the previous theoretical ideas and the expected results. Conclusion: The quality of life scale of peritoneal dialysis patients has a good reliability and validity, which can be applied in the evaluation of quality of life of peritoneal dialysis patients in our country.
