Abstract

This exploratory study was conducted to develop and validate an instrument for measuring the social impact of food waste at the household level. A mixed methodology was employed, commencing with a qualitative approach through in-depth interviews and focus group discussions, to identify the social impact of food waste at the household level. This was followed by a quantitative assessment of the questionnaire's validity and reliability. The process involved seven experts for content validity testing, 150 households for face validity testing, and 202 households for reliability testing. The content validity revealed an I-CVI 0.86-1 and a kappa statistic 0.85-1. The face validity demonstrated I-FVI ≥ 0.90 and S-FVI ≥ 0.95. Additionally, the Cronbach's alpha for the reliability test was 0.743. The questionnaire proved to be a simple, valid, and reliable instrument for measuring the social impact of household food waste. •Mixed method used in developing and validating the questionnaire.•Content validity, face validity, and reliability testing to evaluate a newly developed instrument.
