Objective: Hospice interdisciplinary team (IDT) providers' attitudes toward sexual and gender minority (SGM) patients and family caregivers impacts quality of care and end-of-life outcomes. This study assessed hospice IDT provider attitudes toward SGM patients and caregivers and identified demographic predictors.; Methods: Hospice IDT providers (N = 122) completed an adapted 11-item scale measuring attitudes toward SGM hospice patients and caregivers. Descriptive statistics, confirmatory factor analysis, and regression models were conducted.; Results: The hospice-adapted Attitudes Toward LGBT Patients Scale (ATLPS) demonstrated acceptable Cronbach's alpha (0.707). Total scores ranged from 32 to 55 (M = 47.04, SD = 5.64) showing that attitudes were generally positive. Being religious (B=-3.169, p = 0.008) was associated with more negative attitudes, while higher education (B = 1.951, p = 0.002) and time employed in hospice agency (B = 0.600, p = 0.028) were associated with more positive attitudes.; Conclusion: This is among the first studies to assess SGM-specific hospice IDT attitudes. Participants had relatively positive attitudes, influenced by religious beliefs, clinical experience, and education. CFA results suggest the need for better instruments to measure this complex construct.; Practice Implications: Education incorporating evidence of disparities, life-course perspectives, and end-of-life experiences of diverse cohorts of SGM patients and families may build on hospice IDT members' experience and training by influencing attitudes, reducing bias and improving competency.
