摘要
目的 在动机性访谈和简短的行动计划(BAP)制定基础上,结合以往的健康促进行为量表编制适用于植入输液港患者的健康促进行为量表。方法 根据对38名患者的动机性访谈和67名患者BAP开放性问卷的结果,分析量表的关键因子并编制预量表;根据90名患者的调查数据对预量表进行探索性因素分析并据此结合专家意见调整条目形成正式量表;由216名患者检验正式量表的信效度;间隔2周后从216名患者中抽取40名进行正式量表重测。结果 正式的植入输液港患者的健康促进行为量表包括行为动机、疾病知识、运动知识、压力管理以及社会支持5个维度,共30个条目,量表及各因子的Cronbach's α系数为0.887~0.944,重测信度为0.889~0.945,各因子复合信度(CR)值为0.941~0.967;聚敛效度平均方差提取(AVE)值则为0.733~0.807,AVE平方根范围为0.856~0.898;五因子模型拟合优秀[χ^(2)/df=2.96,近似误差均方根(RMSEA)=0.07,增值拟合指数(IFI)=0.934,Tucker-Lewis指数(TLI)=0.963,比较拟合指数(CFI)=0.919,拟合优度指数(GFI)=0.961]。各因子与量表的相关系数为0.561~0.941。正式量表总分与3种效标量表的得分均呈正相关(P<0.001)。结论 针对植入输液港患者编制的健康促进行为量表具有良好的信效度,可用于植入输液港患者健康促进行为的评估。
Objective To develop a health-promoting behavior scale for patients with totally implantable venous access ports(TIVAP)based on motivational interviewing and brief action planning(BAP).Methods Key factors were identified through motivational interviews with 38 patients and open-ended BAP questionnaires from 67 patients to draft a preliminary scale.Exploratory factor analysis(EFA)was performed using survey data from 90 patients,with items adjusted per EFA results and expert feedback to form the formal scale.Reliability and validity examinations were tested with 216 patients;40 patients from this cohort underwent retesting after 2 weeks.Results The final scale comprised 30 items across five dimensions:behavioral motivation,disease knowledge,exercise knowledge,stress management,and social support.Cronbach′sαcoefficients were 0.887-0.944 for the total scale and subscales.The test-retest reliability was 0.889-0.945;and composite reliability(CR)values were 0.941-0.967.Convergent validity was confirmed with average variance extracted(AVE)values of 0.733-0.807 and square roots of AVE ranging from 0.856 to 0.898.The five-factor model demonstrated excellent fit[χ^(2)/df=2.96,root mean square error of approximation(RMSEA)=0.07,incremental fit index(IFI)=0.934,Tucker-Lewis index(TLI)=0.963,comparative fit index(CFI)=0.919,goodness-of-fit index(GFI)=0.961].Subscale-total scale correlations were 0.561-0.941.The total score positively correlated with three criterion scales(P<0.001).Conclusion The scale demonstrates good reliability and validity for health-promoting behaviors in TIVAP patients,which can be used to assess health-promoting behaviors of these patients.
