HHFA Building structure June 2023

Overview

Each of the four HHFA modules contains a set of stand-alone questionnaires that may be “Core”, “Core+Additional” and/or “Supplementary” questionnaires.

• A Core questionnaire contains only core questions.
• A Core+Additional questionnaire contains both core and additional questions.
• A Supplementary questionnaire does not include questions from the other HHFA questionnaires. It is designated “Core” or “Additional” based on the questions included and may collect data through a different modality from the other questionnaires (e.g. record review, clinical vignette).
