Further psychometric evaluation of the eight-item hospice philosophy scale : results from a national sample of interdisciplinary hospice clinicians
Article indépendant
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, 2(19) = 48.38, p < .001 (RMSEA = .06, SRMR = .03, CFI = .98, TLI = .97). “Multiple indicators, multiple causes” model results indicated differential item functioning by age, race, and/or professional discipline on five items. However, subsequent uncorrected and differential item functioning-corrected models detected no statistically significant HPS-8 mean differences by grouping variables. Composite reliability results (CR = .82) demonstrated acceptable internal consistency reliability. Our results support the HPS-8 as a valid and reliable measure of attitudes toward the hospice philosophy of care in hospice clinicians.
