Australian mental health practitioners’ reported practice, beliefs, and barriers to the prescription of dietary change for mental health conditions

Objective: To investigate self-reported practice, beliefs, and barriers regarding prescription of dietary change for mental health from a range of mental health practitioners across Australia.

Method: An online survey was completed by 193 Australian mental health practitioners.

Results: Over 50% of practitioners reported prescribing dietary change for stress, depression, and anxiety at least weekly in their practice. Over half the practitioners considered dietary change to be 60-100% useful for enhancing mental health outcomes. Approximately one-quarter of the practitioners considered dietary change to be less than 40% useful for treating mental health conditions. Thematic analysis revealed the most frequently reported higher-order barrier themes were practitioner barriers (43.8%) and client barriers (29.2%), with insufficient skills and knowledge (15.9%) and client adherence (12.8%) being commonly cited initial codes.

Conclusion: Mental health practitioners in Australia prescribe dietary change for mental health. However, barriers to prescription of dietary change for mental health need be addressed to overcome challenges associated with using it as a therapeutic intervention for mental health conditions. Universities and university training accreditation bodies should consider providing more extensive instruction in psycho-nutrition as part of mental health practitioners’ training. Likewise, further recognised professional development should be offered, and awarded, for already qualified practitioners.
