肿瘤患者PICC自我管理能力量表的构建及测评

Development and validation of the Cancer Patients PICC Self-management Scale

目的编制肿瘤患者PICC自我管理能力量表并验证其信效度。方法通过文献查阅、患者及PICC门诊护士访谈,编制肿瘤患者PICC自我管理能力初始量表,通过专家咨询、预试验后,对256例PICC置管肿瘤患者进行正式测评。结果探索性因子分析得到日常导管观察、导管维护依从性、导管管理信心、异常情况处理、信息获取、带管运动、带管日常生活7个因子35个条目,方差累积贡献率62.260%;量表的内容效度0.922;Cronbach′sα系数0.904,重测信度0.933。结论肿瘤患者PICC自我管理能力量表具有良好的信、效度,可以用来测量肿瘤患者PICC自我管理能力。

Objective To develop the Cancer Patients PICC Self-management Scale （CPPSM）, and to test its validity and reliability. Methods Initial version of the CPPSM was formulated by using literature reviewing and in-depth interviewing of patients and PICC nurse specialists. Totally, 256 cancer patients with PICC completed the CPPSM after expert consultation and pre-test of the scale. Results Seven factors containing 35 items were extracted by using exploratory factor analysis： daily observation of catheters, com- pliance with catheter maintenance, confidence in catheter management, handling of abnormal events, information access, exercises with catheters, and daily life with catheters; the 7 factors explained 62. 26% of the total variance. The content validity index （CVI） was 0. 922, and the Cronbachs a was 0. 904 and test-retest reliability coefficient was 0. 933. Conclusion The self-designed CPPSM has good validity and reliability, which can be applied to assess self-management ability of cancer patients with PICC.
