Development and psychometric validation of a comprehensive end-of-life care competence scale: A study based on three-year surveys of health and social care professionals in Hong Kong.

Abstract

This study aimed to develop an assessment tool measuring comprehensive interdisciplinary competence in end-of-life care (EoLC) and investigate its content, construct validity, reliability, and their correlates. Items of the Comprehensive End-of-Life Care Competence Scale (CECCS) were developed according to a comprehensive core competence framework in EoLC and refined by a multi-disciplinary panel of experts. The psychometric properties were further tested through region-wide surveys of self-administered questionnaires completed by health and social care professionals in Hong Kong. Participants comprised social workers, nurses, physicians, and allied health care professionals (445 participants in 2016, 410 in 2017, and 523 in 2018). Factor analysis validated the construct of the questionnaire which encompassed 26 items describing EoLC core competences in seven domains with satisfactory internal reliability (confirmatory factor analysis: χ2/df = 3.12, GFI = 0.85, TLI = 0.93, CFI = 0.94, RMSEA = 0.07; Cronbach's alphas ranged from 0.89 to 0.97): overarching value & knowledge, communication skills, symptom management, psychosocial and community care, end-of-life decision-making, bereavement care, and self-care. Higher perceived levels in these competences were correlated with a higher level of job meaningfulness and satisfaction (r ranged from 0.17 to 0.39, p < 0.01) and correlated with lower perceived stress (r ranged from -0.11 to -0.28, p < 0.05). Regression analysis found that age and work involvement in EoLC were positively associated with the perceived competences in all domains; professionals working in hospices reported higher levels of competence than workers in other settings; social workers showed lower perceived competences in symptom management, but higher levels in bereavement care than other health care professionals. The validity and internal reliability of CECCS were demonstrated. The levels of perceived competences working in EoLC were significantly associated with professionals' job-related well-being. Practically, there is still room for improvement in comprehensive competences among health and social care workers in Hong Kong.
