Measuring child food insecurity requires accurate, reliable, and complete information from children themselves. Children have the most complete knowledge about their own lives and experiences [60, 61], and child self-report is widely seen as the "gold standard" for assessing children's internal experiences such as quality of life [60], exposure to domestic violence [62], and pain [60]. Although children are the only accurate reporters of their food insecurity, it is important to note that what they are reporting - child food insecurity - may be substantively different to adult and household food insecurity. Adult food insecurity has been shown to have four core domains: compromises in the quantity and quality of food, and psychological and social strains related to food hardships.
