Validating scales to assess learning about sustainable food through university gardens
Purpose-University gardens are innovative educational spaces that facilitate posing
topics relevant to civic education, such as healthy and sustainable eating. This work aims
to provide reliable quantitative tools to assess learning about sustainable food practices
after garden-based interventions within higher education.
Design/methodology/approach-Based on their previous qualitative research on learning
promoted by garden-basedinterventions, the researchers designed two Likert-scale
questionnaires. The first is the "Growing Food Habits_Purchase" (GFH_P) scale, which
informs on the habits or profiles of people who can make food purchasing decisions. The
second is the “Growing Food Habits_Intake” (GFH_I) scale, which informs on the habits
or profiles of people regarding food consumption (diet).
Findings- After validation, GFH_P consists of 14 items in four dimensions (reliability
through McDonald’ ω = 0.721; Total Variance Explained = 52.97%), and GFH_I consists
of 12 items in four dimensions (ω = 0.872; TVE = 60.699%). These two scales constitute
valuable tools for applying before and after educational interventions at university
gardens to assess progress in food purchasing and intake habits. Their use can
demonstrate the actual contribution of garden-based learning to the transition toward
more sustainable diets that is key to transforming the food system.
Originality- This work responds to the need for quantitative instruments that allow for a
rigorous evaluation of the academic impacts of garden-based learning. To date, there were
no validated questionnaires to assess the educational impact of gardens as teachinglearning
environments for food education.
