Limited Capacity seats available

Component Type: Workshop
Level: Intermediate

One aspect of patient-reported outcome (PRO) instrument development that continues to perplex the field is the interpretation of change scores. How much change must be observed on a PRO instrument to be able to say that a patient has experienced a treatment benefit? This session will provide a brief background on commonly-used and novel methods for assigning meaning to PRO score changes, and then attendees will participate in one of three activities where these methods are demonstrated. The goal of the methods demonstrated in each of these three activities is to identify a threshold at which changes on the PRO instrument are deemed meaningful. The first activity will be a mock exit interview where a participant is probed about their experience during a clinical trial and the meaning behind their observed PRO scores. The second activity will be a mock bookmarking exercise where a participant rates hypothetical vignettes as better, worse, or the same as their own condition using items from a PRO instrument. The third activity will be a group exercise on synthesizing results from multiple methods into one responder definition (i.e., the triangulation process). The session attendees will reconvene at the end of these exercises to discuss the value and challenges of each method.

**Due to session format, seating will be limited to 50 participants and available on a first come, first served basis. Once all seats are occupied, DIA will be required to close the session, and no more participants will be admitted. Interested attendees are encouraged to arrive early in order to ensure seating.

Learning Objectives

Recognize the value of and challenges with different methods for informing the interpretation of change on PRO instruments by engaging in mock exercises demonstrating these methods in practice.
