- Development and validation of an eating behavior patient‐reported outcome measure in people living with obesity or overweight Donald M. Bushnell Shirley Fung Meryl Brod Carl A. Roberts Carel W. Le Roux Oren Steen Kathryn J. Lucas Anita M. Hennige Anastasia Uster Obesity AbstractObjectiveThe objective of this study was to develop a measure of eating behaviors in adults living with obesity or overweight.MethodsBased on concept‐elicitation (n = 53) and cognitive‐debriefing (n = 15) studies, a draft eating behavior patient‐reported outcome (EB PRO) measure was developed. Its psychometric properties were established using data from a 46‐week clinical trial of an investigational antiobesity medication (n = 387).ResultsThe final EB PRO comprised 12 items across two domains (i.e., “Desire to Eat” and “Capacity to Resist”; 6 items each) and a Total Eating Behavior score (0–48; higher scores worse). The EB PRO demonstrated good test–retest reliability (intraclass correlation coefficients > 0.7). Confirmatory factor analysis showed a comparative fit index of 0.98 with good internal consistency (Cronbach α > 0.7). The EB PRO generally exhibited moderate‐to‐large correlations with the Patient Global Impression of Severity questionnaire and Three‐Factor Eating Questionnaire and weaker correlation with the 36‐Item Short‐Form Health Survey version 2 Physical Functioning scale. All EB PRO scores improved from baseline to week 46 (p < 0.0001), demonstrating sensitivity to change with therapy. Clinically meaningful thresholds were defined as eight‐ and four‐point changes in Total Eating Behavior and domain scores, respectively.ConclusionsThe EB PRO measure is a promising tool for assessing eating behaviors in people with obesity or overweight. 10.1002/oby.24299 http://creativecommons.org/licenses/by/4.0/
