经外周静脉置入中心静脉导管化疗患者自我管理行为测评量表的开发

Development of self-management behavior assessment scale for chemotherapy patients with PICC

目的 开发PICC化疗患者自我管理行为测评量表,并进行效度和信度检验.方法 参考美国斯坦福大学患者教育研究中心创建的《慢性病自我管理研究测量表》及其评分标准,结合PICC患者自我管理内容,经参考文献、专家评定,修订成《PICC化疗患者自我管理行为测评量表》.量表包括5个维度,19项量化指标,共78个条目.2010年2月至2011年11月192例乳腺癌PICC化疗患者参加了调查.结果 有效问卷178份,量表的CVI为0.906,总体Cronbachα系数为0.892.采用因子分析法,提取出特征根＞1的公因子4个,解释总方差的41.180％,每个条目在相应因子上的负荷均在03以上.结论 此测评量表具有较好的效度和信度,为研究者提供了PICC化疗患者自我管理行为评价和干预的工具.

Objective To develop self-management behavior assessment scale for chemotherapy patients with peripherally inserted central catheter （PICC）,and test the validity and reliability of it.Methods In reference to ＂Chronic Disease Self Management Study Measure＂ and its scoring standard by patient education and study center of American Stanford University,in combination with PICC patient self-management content,with reference to the literature,expert assessment,the self-management behavior assessment scale was established.The scale included five dimensions,19 quantitative indicators,a total of 78 entries.From February 2010 to November 2011 192 cases of breast cancer chemotherapy patients with PICC participated in the survey.Results Effective questionnaire was 178 copies,scale of content validity index （CVI） was 0.906,the overall Cronbach alpha coefficient was 0.892.Using factor analysis method,4 common factors were extracted whose characteristic root was greater than 1,and could explain 41.180% of the total variance,each item on the corresponding factor of load was above 0.3.Conclusions The evaluation scale has good validity and reliability,which can provide researchers with a tool to evaluated and intervene with self management behavior of breast cancer chemotherapy patients with PICC.
