Readiness for death may affect the quality of the death experience and influence response to treatments. The psychologic vulnerability of the dying person is a major focus of palliative care. Accurate assessment of readiness for death may lead to earlier and more appropriate interventions.
The purpose of this study was to assess the psychometric properties of the revised readiness for death instrument.
Using a known groups technique and a cross-sectional study design, the revised instrument was administered to 52 elders in hospice care with a terminal diagnosis and 91 community dwelling adults without a terminal diagnosis.
Instrument content validity (Kappa = 0.96) was supported by three expert panelists who were hospice researchers. Principal components factor analysis explained 43% of the variance and partially supported the proposed four-factor structure of the revised 26-item instrument. Internal consistency was acceptable (.76). Discriminant validity was significant as assessed by an independent t-test between two contrast groups (t = 5.98, p = 0.000). The factor analysis, reliability testing, and qualitative analysis of items supported deletion of 2 items.
Results indicated that the revised instrument has sound psychometric properties but further testing with a larger sample of hospice subjects is needed to confirm the factor structure of the instrument.
对死亡的准备状态可能会影响死亡体验的质量,并影响对治疗的反应。临终者的心理脆弱性是姑息治疗的主要关注点。准确评估对死亡的准备状态可能会带来更早且更合适的干预措施。
本研究的目的是评估修订后的死亡准备状态量表的心理测量特性。
采用已知群体技术和横断面研究设计,将修订后的量表施用于52名患有终末期诊断的临终关怀机构中的老年人以及91名无终末期诊断的社区居住成年人。
量表的内容效度(Kappa = 0.96)得到了三名临终关怀研究专家小组成员的支持。主成分因子分析解释了43%的方差,并部分支持了修订后的26项量表所提议的四因素结构。内部一致性可接受(.76)。通过两个对比组之间的独立t检验评估,判别效度显著(t = 5.98,p = 0.000)。因子分析、信度测试和项目定性分析支持删除2个项目。
结果表明,修订后的量表具有良好的心理测量特性,但需要对更大样本的临终关怀对象进行进一步测试,以确认该量表的因子结构。
