This study attempted to develop a scale that measures the level of patients' recognition of the nurses' care, based on Watson's caring theory, and confirmed its reliability and validity.
The items were developed through a literature review and an expert content validity test. The questionnaires were administered to 285 inpatients of internal medicine and surgical units at two general hospitals. Construct validity was tested using exploratory and confirmatory factor analysis, and reliability was tested using Cronbach's alpha.
This process resulted in a preliminary scale composed of 34 items; We used item analysis and five exploratory factor analyses, and consequently selected 14 items composed of three factors (respect, genuineness, and relationality). The confirmatory factor analysis verified the model fit and convergent and discriminant validity of the final items; criterion validity was confirmed with the positive correlation with the measurement scale of the patient-perceived quality of nursing . The overall scale reliability had a Cronbach's alpha of .92, which indicated internal consistency and reliability.
The developed scale showed content, construct, and criterion validity, and reliability, as well as convergent validity for each item and discriminant validity between the factors. This makes it suitable for use in a diverse range of future studies on nurse communication using structural equation models.
本研究试图基于沃森关怀理论开发一种量表,以测量患者对护士关怀的认知水平,并验证其信效度。
通过文献回顾和专家内容效度测试来确定条目。对两家综合医院内科和外科的285名住院患者进行问卷调查。采用探索性和验证性因素分析来检验结构效度,使用克朗巴哈α系数来检验信度。
这一过程产生了一个由34个条目组成的初步量表;我们进行了项目分析和五次探索性因素分析,最终选取了由三个因素(尊重、真诚和关系性)组成的14个条目。验证性因素分析验证了最终条目的模型拟合度、收敛效度和区分效度;与患者感知护理质量测量量表的正相关证实了效标效度。总量表信度的克朗巴哈α系数为0.92,表明具有内部一致性和信度。
所开发的量表显示出内容效度、结构效度、效标效度和信度,以及各条目的收敛效度和因素间的区分效度。这使其适用于未来使用结构方程模型进行的关于护士沟通的各种研究。
