Mother-Baby Study - Relative Reinforcing Value (RRV)

September 3, 2026 updated by: Julie Lumeng, University of Michigan

Fundamental Biobehavioral Mechanisms Underlying the Integrated Development of Emotion, Attachment, and Nutritive Intake in the Mother-Infant Dyad

The study will test a model of biobehavioral mechanisms involved in the development of a system of emotion, attachment, and nutritive intake in the mother-infant dyad and the association of this system with maternal feeding behavior, child eating behavior, dietary intake, and adiposity.

To participate in this study the infant must also be enrolled in long-term observational study, NCT06039878.

Detailed Description

This interventional task is done with children while they are in the long-term observational study, NCT06039878, at approximately ages 18 and 36 months. In the observational study there are 300 participants (150 mothers and 150 children). In this trial only data from the children is collected and therefore only 150 participants are listed.
