护士促进癌症幸存者体力活动知信行问卷的编制及信效度检验

目的 编制护士促进癌症幸存者体力活动知信行问卷并检验其信效度。方法 以知信行理论为指导，通过文献回顾、查阅指南、头脑风暴、专家函询、预调查后形成初始问卷，便利选取553名肿瘤相关科室护士进行调查，对问卷进行项目分析及信效度检验。结果 问卷由知识、信念、行为3个维度共30条目构成。总问卷的Cronbach α系数为0.950，折半信度为0.682，重测信度为0.900。探索性因子分析提取3个公因子，累计方差贡献率为58.252%。验证性因子分析显示：χ²/df=2.395,RMSEA=0.073,NFI=0.849,IFI=0.906,TLI=0.897,CFI=0.906，模型拟合良好。内容效度分析显示，条目水平内容效度指数(I-CVI)为0.833～1.00，平均量表水平内容效度指数(S-CVI/Ave)为0.969，全体一致量表水平内容效度指数(S-CVI/UA)为0.800。结论 该问卷具有良好的信效度，可用于评估我国肿瘤科护士在促进癌症幸存者体力活动方面的知识、信念和实践水平。

Development and Psychometric Testing of Knowledge-belief-practice Questionnaire for Nurses to Promote Physical Activity in Cancer Survivors

Objective To develop and test the reliability and validity of a knowledge-belief-practice questionnaire for nurses to promote physical activity in cancer survivors. Methods Based on the KAP theory, the draft questionnaire was developed after literature review, guideline review, brainstorming, expert consultation and pilot survey. With convenient sampling, 553 nurses from oncology-related departments were selected and investigated to test the reliability and validity of the questionnaire. Results The questionnaire consisted of 30 items covering 3 dimensions: knowledge, belief and practice. The Cronbach's alpha coefficient of the total questionnaire was 0.950; the split-half reliability coefficient 0.682, and the retest reliability 0.900. Exploratory factor analysis extracted 3 common factors, which could explain 58.252% of the total variance. Confirmatory factor analysis showed that the fitting index of the scale structure model was good：χ²/df=2.395,RMSEA=0.073,NFI=0.849,IFI=0.906,TLI=0.897,CFI=0.906. Content validity analysis showed that I-CVI was 0.833~1.000; S-CVI/Ave 0.969; and S-CVI/UA 0.800. Conclusion The questionnaire has good reliability and validity and can be used to evaluate the knowledge, belief and practice of oncology nurses to promote physical activity of cancer survivors in China.
