This systematic mixed-studies review, prospectively registered on PROSPERO (CRD42020215775), explored the role of psychologists, and the facilitators and barriers they experience, in supporting clients with illness-related dying and death. A search of six research databases was conducted in October 2023. Fifty-one studies, mainly qualitative and from the perspectives of psychologists, met inclusion criteria. Thematic synthesis highlighted how psychologists provided expertise across various contexts. They supported clients with preparing for death, and adjusting to dying, provided professional consultancy and support, and undertook leadership in enhancing psychological end-of-life care. Results illustrated the sustaining factors and ongoing challenges working in end-of-life care, namely, the unique nature of navigating the death space, recognition and awareness of psychologists' contribution, and the support, training and development required. Given the universality of dying and death, this review is relevant to psychologists working within and beyond more traditional end-of-life care contexts, such as employee assistance programs, private practice, schools, and other psychological services. Policy, clinical and research implications are discussed, including the need for greater engagement and training of psychologists in the dying and death space.
