Nurses must be comfortable facilitating palliative and end-of-life communication with patients and their families.
A validated instrument measuring the comfort of nurses with conducting end-of-life communication is essential for meeting the goals and wishes of patient care. This study aimed to develop and conduct a psychometric evaluation of the Comfort with Communication in Palliative and End-of-Life Care (C-COPE) instrument.
Face, content, and construct validity, including test-retest reliability, were conducted.
Four experts subjectively confirmed face content validity and the quantitative item content validity index (I-CVI) ranged from 0.67 to 1 and scale content validity index (S-CVI/Ave) was 0.98. Principal axis factoring with Promax rotation yielded a five-factor solution accounting for 66.2% of the variance. The items loading on the five factors ranged from 0.46-0.96 (factor 1), 0.67-0.93 (factor 2), 0.49-0.86 (factor 3), 0.68-0.79 (factor 4), and 0.24-0.96 (factor 5). Internal consistency reliability (coefficient a) was 0.90 for the total C-COPE, and above 0.75 for each factor. The five factors are 'cultural/spiritual considerations,' 'team considerations,' 'addressing decision-making,' 'addressing symptomatology,' and 'deliberate awareness.' Test-retest reliability yielded an intraclass correlation coefficient (ICC) of 0.87 (CI 95%, 0.82-0.91).
The C-COPE is a reliable and valid instrument measuring nurse comfort with palliative and end of-life care communication, yet requires testing in more diverse samples.
护士必须能够与患者及其家属舒适地进行姑息治疗和临终沟通。
衡量护士进行临终沟通舒适度的验证工具对于实现患者护理的目标和愿望至关重要。本研究旨在开发并进行姑息治疗和临终关怀沟通舒适度量表（C-COPE）的心理测量评估。
进行了表面、内容和结构有效性评估，包括测试-重测信度。
四位专家主观确认了表面内容有效性，定量项目内容有效性指数（I-CVI）范围为 0.67 至 1，量表内容有效性指数（S-CVI/Ave）为 0.98。采用 Promax 旋转的主成分因子分析得出一个五因素解决方案，占方差的 66.2%。五个因素的项目负荷范围为 0.46-0.96（因素 1）、0.67-0.93（因素 2）、0.49-0.86（因素 3）、0.68-0.79（因素 4）和 0.24-0.96（因素 5）。C-COPE 的总内部一致性信度（系数 a）为 0.90，每个因素均高于 0.75。五个因素是“文化/精神考虑”、“团队考虑”、“解决决策问题”、“解决症状”和“有意识的意识”。测试-重测信度产生了 0.87 的组内相关系数（ICC）（95%CI，0.82-0.91）。
C-COPE 是一种可靠且有效的衡量护士对姑息治疗和临终关怀沟通舒适度的工具，但需要在更多样化的样本中进行测试。
