Applying Novel Technologies and Methods to Inform the Ontology of Self-Regulation: Binge Eating and Smoking

Not Recruiting

Trial ID: NCT03353649

Purpose

This study aims to examine targets of self-regulatory function among two exemplar populations for which behavior plays a critical role in health outcomes: smokers and individual who binge eat (BED). This is the second phase of a study that aims to identify putative mechanisms of behavior change to develop an overarching "ontology" of self-regulatory processes.
