Further Psychometric Evaluation of the Eight-Item Hospice Philosophy Scale: Results From a National Sample of Interdisciplinary Hospice Clinicians.

This study examined the psychometric properties of the eight-item Hospice Philosophy Scale (HPS-8) through confirmatory factor analysis; differential item functioning by age, gender, race, and professional discipline; and internal consistency reliability. We administered the HPS-8 to a national convenience sample of 471 interdisciplinary hospice clinicians. Confirmatory factor analysis results supported a one-factor model with an error correlation between two similarly worded items, χ(19) = 48.
