This paper is a report of a study conducted to develop and test the psychometric properties of the Nurse-Physician Collaboration Scale.
The importance of cooperation between healthcare professionals is widely acknowledged in Europe and the United States of America, but there have been no specific studies of interactions between healthcare professionals or of nurse-physician cooperation in Japan.
The 51-item Nurse-Physician Collaboration Scale was developed using a process of item design, item refinement, and testing for reliability and validity. Random sampling was used to identify potential respondents from 27 of the 87 acute care hospitals in one city in Japan in 2006. Valid responses were obtained from 446 physicians and 1217 nurses (response rate 78.7% for nurses, and 54.4% for physicians). Construct validity was first confirmed by an exploratory factor analysis and then by a confirmatory factor analysis. Finally, a simultaneous analysis of several groups was performed. The test-retest method and Cronbach's alpha coefficients were used to assess reliability.
Exploratory factor analysis yielded three factors. The three-factor models were confirmed by a confirmatory factor analysis (CFI >0.9, RMSEA <0.08). Simultaneous analysis of several groups (RMSEA = 0.046, AIC = 3115.888) showed the same factor structure for both nurses and physicians. The r values of the test-retest reliability correlations were all 0.7 or above. Internal consistency was demonstrated by a Cronbach's alpha = 0.8 or above.
The Nurse-Physician Collaboration Scale can be used to establish standards for nurse-physician collaboration, to measure the frequency of collaborative activity, and to verify unit-specific relationships between collaboration and quality of care.
本文报告一项旨在开发和测试护士 - 医生合作量表心理测量特性的研究。
医护人员之间合作的重要性在欧洲和美国已得到广泛认可，但在日本，尚未有针对医护人员之间互动或护士 - 医生合作的具体研究。
通过项目设计、项目优化以及可靠性和有效性测试的过程，开发了包含51个条目的护士 - 医生合作量表。2006年，采用随机抽样的方法从日本一个城市87家急症护理医院中的27家选取潜在受访者。获得了446名医生和1217名护士的有效回复（护士的回复率为78.7%，医生的回复率为54.4%）。首先通过探索性因素分析确认结构效度，然后进行验证性因素分析。最后，对几组数据进行了同时分析。采用重测法和克朗巴哈α系数评估可靠性。
探索性因素分析得出三个因素。验证性因素分析（CFI>0.9，RMSEA<0.08）证实了三因素模型。几组数据的同时分析（RMSEA = 0.046，AIC = 3115.888）表明，护士和医生具有相同的因素结构。重测信度相关性的r值均在0.7及以上。克朗巴哈α系数为0.8及以上，表明具有内部一致性。
护士 - 医生合作量表可用于建立护士 - 医生合作的标准，测量合作活动的频率，并验证特定科室合作与护理质量之间的关系。
