Scoring protocol for Four Domain Food Insecurity Scale (4D-FIS). This protocol was based on qualitative data from the nutrition interview summaries and responses to the Four Domain Food Insecurity Scale (4D-FIS). Responses of “often” and “sometimes” were counted as affirmative responses. Affirmative responses to the quantitative subscale were counted as more severe than affirmative responses to the non-quantitative (qualitative, psychological, and social) subscales.
