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. Key Points What is already known about this topic: Diet is becoming more accepted as having a substantial influence upon mental health. Improving diet quality has been acknowledged as serving a protective role in reducing the rate of cognitive decline. The importance of dietary change remains underestimated by mental health professionals for the treatment of mental health maladies. What this research adds: Results demonstrated over 50% of the sample of mental health practitioners reported prescribing dietary change for stress, depression, and anxiety at least daily or weekly in their practice. Approximately a third of the mental health practitioners reported believing dietary change to be 80-100% useful for mental health outcomes. Most frequently reported barriers to the prescription of dietary change for mental health were practitioner barriers (43.8%) and client barriers (29.2%) higher-order themes, with insufficient skills and knowledge (15.9%) and client adherence (12.8%) being commonly cited initial codes.
