To develop and test two instruments measuring decision making about level of aggressiveness of intensive care unit (ICU) patient care. Decisions about Aggressiveness of Patient Care (DAC) measures care providers' general perceptions about decision making. Decisions about Aggressiveness of Patient Care for Specific Patients (DAC[SP]) measures perceptions in specific situations.
Two-phase psychometric instrument evaluation.
Phase I, nationally mailed questionnaire. Phase II, northeastern medical center medical ICU.
Phase I, 22 ICU nurse and physician experts. Phase II, 35 medical ICU staff nurses and eight medical resident physicians.
Psychometric properties of instruments.
Content validity of both tools was supported by their development from the literature and by the experts. Face validity was supported by the experts, staff nurses, and medical resident physicians. Both instruments had variance in responses, internal consistency reliability (r = 0.53, r = 0.73) and, test-retest reliability (r = 0.73).
These instruments may enrich our understanding of how care providers make bioethical decisions for ICU patients. Such understanding could assist with development of interventions to increase collaborative interdisciplinary decision making, leading to increased care provider satisfaction and better patient outcomes.
开发并测试两种用于衡量重症监护病房（ICU）患者积极治疗程度决策的工具。患者护理积极程度决策（DAC）衡量护理人员对决策制定的总体认知。特定患者的患者护理积极程度决策（DAC[SP]）衡量特定情况下的认知。
两阶段心理测量工具评估。
第一阶段，全国范围内邮寄问卷。第二阶段，东北部医疗中心的医学重症监护病房。
第一阶段，22名ICU护士和医生专家。第二阶段，35名医学重症监护病房的护士和8名内科住院医师。
工具的心理测量特性。
两种工具的内容效度均得到文献及专家的支持。表面效度得到专家、护士和内科住院医师的支持。两种工具在回答上存在差异，具有内部一致性信度（r = 0.53，r = 0.73）和重测信度（r = 0.73）。
这些工具可能会丰富我们对护理人员如何为ICU患者做出生物伦理决策的理解。这种理解有助于开发干预措施，以增加跨学科协作决策，从而提高护理人员的满意度并改善患者结局。
