UNLABELLED: The Pathway to Planetary Health (PPH) is a theoretical framework that supports dietitians to undertake pro-environmental change within the food system.
AIM: To explore the practical application and impact of the PPH.
METHODS: The PPH was workshopped with dietitians and dietetic students (n = 46) using a mixed-methods case study approach. Data collection was embedded in workshop delivery via a (i) pre-post survey using both Likert scale and free-text responses, and (ii) qualitative explorations of participants' perspectives via interactive workshop activities. Analysis of quantitative data involved an independent samples t-test for normally distributed data and a Mann-Whitney U test for non-normally distributed data. Qualitative data were analysed thematically for survey responses and content analysis for workshop activity responses.
RESULTS: Participants increased their confidence to undertake pro-environmental change in their personal lives 4.1 ± 0.7 to 4.5 ± 0.8/5, and professional lives 3.6 ± 1.1 to 4.3 ± 0.9/5 (p < 0.05). Three themes were identified as barriers and enablers to pro-environmental action, including 'personal', 'social and professional' factors, as well as 'contextual and environmental' influences.
CONCLUSIONS: The application of the PPH framework was supported by workshop participants who significantly increased their confidence to undertake pro-environmental food system change.
