Knowledge and Attitudes Toward Hospice and Palliative Care: Instrument Validation Among Emergency Providers.

Emergency providers can engage in goals of care discussions and hospice and palliative care referrals. Little is known about their knowledge and attitudes, which may influence these care practices. This study aims to re-validate the knowledge and attitude towards hospice and palliative care (KAHP) scale and assess the scale's latent constructs among emergency providers. The scale consists of ten items measured on a five-point Likert scale. Five of the ten items were reverse scored. Content validation was performed by ten experts in Hospice and Palliative Medicine and Emergency Medicine. Baseline surveys of emergency physicians, advance practice providers, and nurses conducted in the context of a pragmatic, randomized control trial were used for the item analysis and the exploratory and confirmatory factor analyses. The KAHP scale is a ten-item scale scored from 10 to 50. Based on the synthesis of content validation results and the item analysis, all ten items were retained. The item and scale Content Validity Index were each .91. The reliability of the scale was .64 and the exploratory factor analysis identified three underlying constructs defined as self-rated knowledge, support for hospice and palliative care practice, and views on provider-patient communication. The presence of good model fit indices supported the structural integrity of the constructs. We present a validated instrument that is suitable for assessing knowledge and attitude variations toward interventions designed to improve hospice and palliative care practice among emergency providers.
