目的:构建适用于护士的COPD肺康复知信行量表，并评价其信效度。方法:以知信行模式为理论框架，经文献回顾、课题研究小组讨论和德尔菲专家函询法拟定初始量表。于2019年10— 12月，采用便利抽样法选取宁夏回族自治区17所二、三级医院304名呼吸内科护士为研究对象进行调查，通过项目分析、探索性因子分析形成正式量表，并检验量表的信效度。结果:护士COPD肺康复知信行初始量表包括54个条目，经过筛选后最终包括知识、态度、行为3个维度和38个条目。量表水平的内容效度指数为0.930，条目水平的内容效度指数为0.830～1.000。量表的Cronbach's α系数为0.972，知识、态度、行为维度的Cronbach's α系数分别为0.957、0.943、0.965，重测信度系数为0.893。采用探索性因子分析提取出3个公因子，累计方差贡献率为63.918%。结论:护士COPD肺康复知信行量表具有良好的信效度，可客观、有效地测评护士COPD肺康复知信行水平，为制订肺康复专科培训计划提供参考依据。“,”Objective:To construct a knowledge, attitude and practice (KAP) scale for chronic obstructive pulmonary disease (COPD) pulmonary rehabilitation for nurses, and evaluate its reliability and validity.Methods:Based on the theoretical framework of KAP model, the initial scale was developed through literature review, research group discussion and Delphi expert letter consultation. From October to December 2019, a total of 304 respiratory nurses from 17 ClassⅡ and ClassⅢ hospitals in Ningxia Hui Autonomous Region were selected as the research subjects by convenient sampling method. Formal scale was formed through item analysis and exploratory factor analysis, and the reliability and validity of the scale were tested.Results:The initial Nurses' Knowledge, Attitude and Practice Scale of Pulmonary Rehabilitation for COPD included 54 items. After screening, it finally included 3 dimensions of knowledge, attitude and practice and 38 items. The content validity index at the scale level was 0.930, and the content validity index at the item level was 0.830 to 1.000. Cronbach's α coefficient of the scale was 0.972, Cronbach's α coefficient of dimensions of knowledge, attitude and practice were respectively 0.957, 0.943 and 0.965, and the test-retest reliability coefficient was 0.893. Three common factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 63.918%.Conclusions:Nurses' Knowledge, Attitude and Practice Scale of Pulmonary Rehabilitation for COPD has good reliability and validity, which can objectively and effectively evaluate the knowledge, attitude and practice level of nurses in COPD pulmonary rehabilitation and provide a reference for formulating pulmonary rehabilitation specialist training plans.
