# _<mark>Notes on comparability</mark>_

The PPCS included two versions of the FIES module, one in the household questionnaire and one in the 18+ individual questionnaire. We use the module from the household questionnaire for this analysis because the frame of reference and response options match those used in the Facebook survey. The FIES module in the PPCS 18+ individual questionnaire refers to the individual (rather than household) experience over the past 12 months, with binary yes/no response options.

The FIES module in the PPCS household questionnaire included an extra item between statements (c) and (d).

Respondents to the Facebook survey were randomly assigned to receive either the FIES module or the RCSI module (described below).

- h) You or any household member went for a whole day and night without eating because there was not enough food

_<mark>Notes on comparability</mark>_ The RCSI module in the PPCS is located in the household questionnaire rather than in the 18+ individual questionnaire.
