Professional supervision in dietetics: a comprehensive, narrative literature review

Aim: This review aims to synthesise the evidence on supervision in dietetics and other health professions to (1) provide an evidence-based definition of supervision for dietetics and (2) translate this evidence to dietetics practice through developing a conceptualisation of the key components of supervision for dietitians. Methods: A comprehensive narrative literature review was used to extract and synthesise supervision research data from (1) four bibliographic databases (Medline, CINAHL, ERIC, ProQuest), (2) two dietetic-specific journals, (3) the databases of two subject matter experts and (4) grey literature including position statements by Australian and international government health and professional governing bodies. The findings were synthesised by consensus between four authors, all supervision specialists. Results: Fifty-one items of scholarship were reviewed and summarised as informing the evidence synthesis. A definition of supervision for dietetics is presented. The conceptualisation of the key elements of supervision includes (1) the supervisor, supervisee, supervisory alliance, and contracting; (2) supervision functions and outcomes; (3) frequency of supervision and (4) formats of supervision. Conclusion: Supervision should form a regular part of all dietitians' practice and commitment to ongoing learning. It is a core component of contemporary dietetic practice and is recommended as a key part of professional development across the professional career trajectory.
