Abstract The study aim was to clarify the essential competencies for psychologists in palliative care teams. A nationwide, multicentre cross-sectional survey was conducted. A 32-item questionnaire assessing endorsement of potential competencies was completed by 70 patients and/or families, 101 consulting personnel, 747 members of palliative care teams and 203 mental health providers. All 32 competencies were judged as essential. Of the 32 items, 9 and 28 items were endorsed by >95% and 80% of participants, respectively. The most frequently endorsed essential competency was ability to coordinate with other professionals in palliative care teams. Some competencies considered essential seemed specific to oncology and medical settings. The results suggest the need for specific guidance for psychologists working in palliative care teams and the development of clinical oncology training programmes and/or systems for psychologists.
