Given the essential role of volunteers in hospice palliative care, it would be beneficial to have a recruitment and retention tool that is reliable and valid. To address this gap, the current investigation sought to adapt and extend the Inventory of Motivations for Palliative Care Volunteerism (IMPCV) of Claxton-Oldfield, Jefferies, Fawcett, Wasylkiw, and Claxton-Oldfield.(1) The purpose of study 1 was to address methodological concerns of the IMPCV using 141 undergraduate students. After conceptually relevant items were added to the IMPCV, participants indicated the degree of influence each of the motivations would have on their, and another person's, decision to become a hospice palliative care volunteer. In both cases, 5 internally consistent subscales were identified through principal components analysis: altruism, civic responsibility, self-promotion, leisure, and personal gain. Convergent and discriminant validity were demonstrated using an established measure of empathy. In study 2, 141 hospice palliative care volunteers completed the revised and renamed Inventory of Motivations for Hospice Palliative Care Volunteerism (IMHPCV). Confirmatory factor analysis provided support for the 5-factor structure of the IMHPCV. The authors encourage other researchers to use the IMHPCV as a measurement tool in studying the motivations of hospice palliative care volunteers.
