目的编制肠造口患者造口知信行量表并对其进行信效度检验,为临床评估肠造口患者的知识、态度、行为提供有效测评工具。方法以知信行理论为框架,采用文献回顾、半结构访谈法、Delphi专家函询法、预调查形成初始量表。选取南昌市3所三级甲等医院在门诊复诊及住院治疗的132例肠造口患者的调查数据进行项目分析、探索性因子分析,进一步筛选条目,并选取220例肠造口患者进行调查,对量表进行信效度检测。结果最终形成的正式量表包括知识、态度、行为3个维度共40个条目,累计方差贡献率为65.18%;总量表Cronbach’sα系数为0.874,折半信度为0.767;总量表内容效度为0.925,各条目的内容效度为0.869~1.000;各维度与量表总分的相关系数为0.632~0.875,各维度之间的相关系数为0.312~0.518。结论肠造口患者造口知信行量表具有较好的信效度,可用于评价肠造口患者的造口相关知识、态度、行为水平。
OBJECTIVE: To develop a stochastic ostatics scale for patients with enterostomy and to test its reliability and validity so as to provide an effective tool for assessing the knowledge, attitude and behavior of patients with enterostoma. Methods Based on the theory of Zhixin Xing, a literature review, semi-structure interviews, Delphi expert inquiry method and pre-investigation were used to form the initial scale. The survey data of 132 cases of enterostoma patients from outpatient referral and inpatient treatment in 3 Grade A first-class hospitals in Nanchang were selected for project analysis, exploratory factor analysis, further screening of entries, and selection of 220 patients with enterostomy, The scale of reliability and reliability testing. Results The final formal questionnaire consisted of 40 items in three dimensions of knowledge, attitude and behavior with the cumulative variance contribution rate of 65.18%. The Cronbach’s alpha coefficient of the total scale was 0.874 and the semi-confidence rate was 0.767. The degree of validity is 0.925, the content validity of each item is 0.869-1.000; the correlation coefficient of each dimension and the total score of the scale is 0.632-0.875, and the correlation coefficient of each dimension is 0.312-0.518. Conclusion Stoma ostatism credit scale in patients with enterostomy has good reliability and validity, which can be used to evaluate stoma related knowledge, attitude and behavior of patients with ostomy.
