Outcome Measures
Primary Outcomes (1)
Decrease in avoidable food waste
The amount of avoidable food waste generated is measured as the difference in weight (grams) between baseline (T0), post-intervention/control (T1), and 6-month follow-up (T2), as assessed by weighed food waste diaries. Participants will complete a food waste diary using a provided kitchen scale and detailed instructions on how to do so. The amount of avoidable food waste will be compared between participants in the Supper Heroes intervention group and those in the control group. Measurement Tool: Food waste diary and kitchen scale. Unit of Measure: Families will be asked to list all food thrown away, the weight of the food (gams) and the reason the food was thrown away (e.g., it went bad) for 7 days. Time Points: Baseline (T0): post-intervention/control (T1 - after completion of either intervention or control activities, 7 weeks); follow-up (T2 - 6 months after completing the intervention or control activities).
