肠造口患者自我照护行为执行意向问卷的研制

Development and validation of a Entorostomy Self-care Implementation Intention Questionnaire

目的编制肠造口患者自我照护行为执行意向问卷并检验其信效度。方法以执行意向理论及其行动计划和应对计划2种具体形式为结构框架,经文献分析、邀请专家进行2轮专家函询形成问卷初稿。便利选取在青岛市某三级甲等医院门诊复诊的265例肠造口患者进行问卷调查,邀请7名专家进行内容效度测评。采用临界比值法、条目与总分相关系数、同质性检验对问卷进行项目分析;采用探索性因子分析、内容效度、内部一致性信度、重测信度对问卷进行信效度检验。结果专家函询过程中,第1轮函询发放问卷27份,回收27份;第2轮函询发放问卷27份,回收25份。2轮专家函询问卷条目的变异系数范围分别为0.066~0.357、0.040~0.199;2轮专家协调程度分别为0.306和0.505,显著性检验P<0.05。形成的肠造口患者自我照护行为执行意向问卷包括2个维度、24个条目,探索性因子分析提取出4个公因子,累计方差贡献率为74.309%;问卷总的Cronbach’sα系数为0.961,重测信度为0.877;总问卷的专家内容效度指数为0.976。结论肠造口患者自我照护行为执行意向问卷具有良好的信效和效度,具有一定的推广价值,可用于测量肠造口患者自我照护行为执行意向现状。

Objective To develop a questionnaire for measuring implementation intention of self-care in patients with enterostomy and to test its reliability and validity.Methods Based on the theory of implementation intention and the two specific forms of action planning and coping planning,the first draft of the questionnaire was formed by inviting 25 experts for two rounds of expert consultation and literature analysis.A total of 265 permanent enterostomy patients from a tertiary hospital in Qingdao were selected by convenience sampling to investigate the draft questionnaire.Seven experts were invited to conduct content validity evaluation.The critical ratio method,the correlation coefficient between items and total scores,and the homogeneity test were used to analyze the questionnaire items.The reliability and validity of the questionnaire were tested by exploratory factor analysis,content validity,Cronbach’s alpha coefficient,and test-retest reliability.Results For the first-round expert consultation,27 e-mails were sent out and 27 responses were received.In the second round,27 emails were sent out and 25 were recovered.The range of coefficient of variation of the 2 rounds was 0.066~0.357 and 0.040~0.199,respectively.The 2 rounds of expert coordination were 0.306 and 0.505 respectively(all P<0.05).The questionnaire consisted of 2 dimensions and 24 items.Four principal factors were extracted by exploratory factor analysis,and the contribution rate of the cumulative variance was 74.309%.The total Cronbach’sαcoefficient of the questionnaire was 0.961,the test-retest reliability was 0.877,and the content index of questionnaire was 0.976.Conclusion The questionnaire has good reliability and validity.It can be used to measure the situation of self-care behavior implementation intention of enterostomy patients.
