Patient-Reported Outcome Measurement Information System (PROMIS) Physical Function

Subjects will participate in a qualitative interview lasting up to 90 minutes. The interviews will include a concept elicitation component to explore details of the subject's perceived disease condition, functional limitations and impacts on daily life and health-related quality-of-life (HRQoL). In addition, a card sorting exercise will be used to evaluate the relevance and comprehension of PROMIS Physical Function items.

PROMIS Physical Function Items is a set of self-report measurement tools. The latest version of PROMIS Physical Function Items contains 165 items for self-assessment. PROMIS Physical Function Cancer Item Bank contains a subset of 45 items relevant to cancer subjects. Subjects will complete half of the PROMIS Physical Function Items during their enrollment visit and the other half of items prior to their interview.
