Development and validation of an eating behavior patient-reported outcome measure in people living with obesity or overweight.

ABSTRACT:

Objective

The objective of this study was to develop a measure of eating behaviors in adults living with obesity or overweight.

Methods

Based on concept-elicitation (n = 53) and cognitive-debriefing (n = 15) studies, a draft eating behavior patient-reported outcome (EB PRO) measure was developed.
