The interviewer asks the participant (or proxy) a series of questions about the level of difficulty he/she has performing everyday activities. These activities may be prohibited by a long-term (chronic) health problem. A hand card with the questions and response options is provided to the participant. Temporary conditions (e.g., broken leg, pregnancy) that prevent the participant from doing the activity do not apply. Questions may be answered by a proxy. Items a., q., r., and s. are not related to physical functioning and may be omitted.
