As aging in the Chinese population increases, the hospitalization rates of patients with dementia have also risen. Research on the difficulties of nurses who care for patients with dementia in Chinese general hospitals is limited. This study aimed to develop a scale to measure the difficulties nurses face in nursing patients with dementia in Chinese general hospitals and to verify its reliability and validity.
Guided by the biopsychosocial theory, an initial scale was created through a literature review, qualitative interviews, and expert consultation. A web-based survey for psychometric testing was conducted with 394 nurses from 11 general hospitals during September to November 2021. Validity was verified using content validity, exploratory factor analysis, the known-groups method, and concurrent validity. Cronbach's α coefficient and split-half reliability were used to assess reliability.
The Item-level Content Validity Index was 0.833-1.000. The Scale-level Content Validity Index was 0.929. Twenty-one items with four factors were extracted from the item analysis and exploratory factor analysis. According to the known-groups method, the difficulty of the experienced group and the group with training experience was significantly lower than that of the less experienced group and the group without training experience. Based on external standards, the correlation coefficient was 0.387 with the Nursing Job Stress Scale and -0.239 with the Dementia Care Attitude Scale. Cronbach's α coefficient for each factor ranged from 0.889 to 0.905, and the total was 0.959. The split-half reliability for each factor ranged from 0.814 to 0.894, and the total was 0.911.
This study discovered a four-factor structure related to the difficulty scale of dementia nursing practice, and the scale's reliability and validity were confirmed. The scale can be utilized to assess the difficulty of dementia nursing practice in general hospitals and may be employed in future research to improve dementia nursing practices.
随着中国人口老龄化加剧，痴呆患者的住院率也有所上升。针对中国综合医院中护理痴呆患者的护士所面临困难的研究较为有限。本研究旨在开发一个量表，以衡量中国综合医院护士在护理痴呆患者时所面临的困难，并验证其信效度。
以生物心理社会理论为指导，通过文献回顾、质性访谈和专家咨询创建初始量表。于2021年9月至11月对来自11家综合医院的394名护士进行了基于网络的心理测量测试。采用内容效度、探索性因素分析、已知群体法和同时效度来验证效度。使用Cronbach's α系数和分半信度来评估信度。
条目水平的内容效度指数为0.833 - 1.000。量表水平的内容效度指数为0.929。从条目分析和探索性因素分析中提取出包含四个因素的21个条目。根据已知群体法，经验丰富组和有培训经验组的困难程度显著低于经验较少组和无培训经验组。以外在标准为依据，与护理工作压力量表的相关系数为0.387，与痴呆护理态度量表的相关系数为 - 0.239。各因素的Cronbach's α系数范围为0.889至0.905，总量表为0.959。各因素的分半信度范围为0.814至0.894，总量表为0.911。
本研究发现了一个与痴呆护理实践困难量表相关的四因素结构，并证实了该量表的信效度。该量表可用于评估综合医院中痴呆护理实践的困难程度，并可能在未来研究中用于改善痴呆护理实践。
