FACT-Item GP5

Functional Assessment of Cancer Therapy - Item GP5

Item GP5 from the FACIT Measurement System

 

Overview

The single FACT-G item, GP5, “I am bothered by side effects of treatment,” is a summary measure of the overall impact of treatment toxicity, based upon its association with the number and degree of adverse events in clinical trials. The single item has demonstrated a significant relationship to overall quality of life as indicated by ability to enjoy life. It has been aligned with the current Food and Drug Administration interest in evaluating the patient’s perspective on treatment of adverse events, and it has been shown to be significantly associated with clinician-reported adverse events.
