Rating scale used to assess subjective satiety (modified from Holt et al 1992). In parallel with a four day weighed food record the participants also recorded their subjective rating of satiation at meal initiation and 30 minutes after meal initiation on a 7-point equal interval, bipolar scale of hunger/fullness modified after Holt et al 1992. This scale was anchored at -3 ("Very Hungry") with a midpoint at 0 ("No particular feeling") through + 3 ("Very Full"). The scale yields numeric results in units termed Rating Scale units (RS). The participants were encouraged to record their subjective rating of satiation between marked intervals if necessary, and this way of recording was common. The recorded subjective satiation was then assessed by TJ to the first decimal. For example, a recorded subjective satiation halfway between "Satisfied" and "Very Full" would yield the result 2.5 Rating Scale units.
