Applying Novel Technologies and Methods to Self-Regulation: Behavior Change Tools for Smoking and Binge Eating

Stanford University91 enrolled

Overview

This study will evaluate the extent to which we can engage and manipulate putative targets within the self-regulation domain within and outside of laboratory settings in samples of smokers and overweight/obese individuals with binge eating disorder. This is the fourth phase of a study that aims to identify putative mechanisms of behavior change to develop an overarching "ontology" of self-regulatory processes.

LaddrBEHAVIORAL

Laddr is an integrated, personalized, web-based self-regulation assessment and behavior change system. It integrates tools that have been shown to be effective for a wide array of behavioral phenomena ranging from substance use and abuse, mental health, risk-taking, chronic pain management, medication adherence, diet, exercise, diabetes and other chronic disease management, and smoking. The organizational structure, functionality and content within Laddr's system centrally embrace these fundamental aspects of behavior change; thus, the Laddr platform is not "diagnosis-specific" but rather enables integrated care for any combination of individuals' goals, needs, and preferences.

Outcomes

Primary Outcomes

Binge Eating Episodes - Loss of Control

Self-reported binge eating episodes is assessed four times daily (morning, early afternoon, late afternoon/evening, and night). A binge eating episode is defined as self-reported overeating and loss of control. Loss of control is assessed by the question "When you ate most recently, did you lose control over your eating?" and is scored as 0 (No), 1 (Yes). Responses provided were averaged across the 28-day period.

Time frame: 28 days

Binge Eating Episodes - Overeating

Self-reported binge eating episodes is assessed four times daily (morning, early afternoon, late afternoon/evening, and night). A binge eating episode is defined as self-reported overeating and loss of control. Overeating is assessed by the question "Since the last prompt, when you ate most recently, did you overeat?" and is scored as 0 (no) or 1 (yes). Responses provided were averaged across the 28-day period.

Time frame: 28 days

Number of Cigarettes Smoked Per Day

Self-reported smoking assessed four times daily (morning, early afternoon, late afternoon/evening, and night). A smoking episode is defined as self-reported smoking of more than zero cigarettes and is assessed by the question "Since the last prompt, how many cigarettes have you smoked?" Participants are asked to input a number into a number field and this was averaged over the 28 day period.

Time frame: 28 days
