Detailed Description
Health risk behavior, including poor diet, physical inactivity, tobacco and other substance use, causes as much as 40% of the illness, suffering, and early death related to chronic diseases. Non-adherence to medical regimens is an important exemplar of the challenges in changing health behavior and its associated impact on health outcomes. Although an array of interventions has been shown to be effective in promoting initiation and maintenance of health behavior change, the mechanisms by which they actually work are infrequently systematically examined. One promising domain of mechanisms to be examined across many populations and types of health behavior is of self-regulation. Self-regulation involves identifying one's goals, and maintaining goal-directed behavior. A large scientific literature has identified the role of self-regulation as a potential causal mechanism in promoting health behavior.
Advances in digital technologies have created unprecedented opportunities to assess and modify self-regulation and health behavior. In this project, we plan to use a systematic, empirical process to integrate concepts across the divergent self-regulation literatures to identify putative mechanisms of behavior change to develop an overarching "ontology" of self-regulatory processes.
This multi-year, multi-institution project aims to identify an array of putative psychological and behavioral targets within the self-regulation domain implicated in medical regimen adherence and health behavior. This is in service of developing an "ontology" of self- regulation that will provide structure and integrate concepts across diverse literatures. We aim to examine the relationship between various constructs within the self-regulation domain, the relationship among measures and constructs across multiple levels of analysis, and the extent to which these patterns transcend population and context. The project consists of four primary aims:
Aim 1. Identify an array of putative targets within the self-regulation domain implicated in medical regimen adherence and health behavior across these 3 levels of analysis. We will build on Multiple PI Russ Poldrack's pioneering "Cognitive Atlas" ontology to integrate concepts across divergent literatures to develop an "ontology" of self-regulatory processes. Our expert team will catalog tasks in the self-regulation literature, implement tasks via online testing (Mechanical Turk) to rapidly obtain large datasets of self-regulatory function, assess the initial ontology via confirmatory factor analysis and structural equation modeling, and assess and revise the resulting ontology according to neural similarity patterns across tasks (to identify tasks for Aim 2).
Aim 2. Evaluate the extent to which we can engage and manipulate putative targets within the self-regulation domain both within and outside of laboratory settings. Fifty smokers and 50 overweight/obese persons with binge eating disorder will participate in a lab study (led by Poldrack) to complete the tasks identified under Aim 1. We will experimentally modulate engagement of targets (e.g., stimulus set of highly palatable foods images or tobacco-related images as well as self-regulation interventions). A comparable sampling of 100 persons will participate in a non-lab study (led by Multiple PI Lisa Marsch) in which we will leverage our novel mobile-based behavioral assessment/intervention platform to modulate target engagement and collect data in real-world conditions.
Aim 3. Identify or develop measures and methods to permit verification of target engagement within the self-regulation domain. Led by Co-I Dave MacKinnon, we will examine cross-assay validity and cross-context and cross-sample reliability of assays. We will employ discriminant and divergent validation methods and Bayesian modeling to refine an empirically-based ontology of self-regulatory targets (to be used in Aim 4).
Aim 4. We will evaluate the degree to which engaging targets produces a desired change in medical regimen adherence (across 4 week interventions) and health behavior among smokers (n=100) and overweight/obese persons with binge eating disorder (n=100) (objectively measured smoking in the former sample and binge eating in the latter sample). We will employ our novel mobile behavioral assessment/intervention platform to engage targets in these samples, given that (1) it offers self-regulation assessment and behavior change tools via an integrated platform to a wide array of populations, and (2) content within the platform can be quickly modified as needed to better impact targets. The proposed project is designed to identify valid and replicable assays of mechanisms of self-regulation across populations to inform an ontology of self-regulation that can ultimately inform development of health behavior interventions of maximal efficacy and potency.
This protocol details the Aim 2 non-lab study led by Multiple PI Marsch.
This phase of the study takes what we learned about self-regulation in the first phase and tests it in two samples that are exemplary for "lapses" in self-regulation: individuals who smoke and overweight/obese individuals with binge eating disorder. We expect that many real-world conditions (e.g., temptation, negative affect) may decrease self-regulation, whereas training through the mobile intervention described below may increase self-regulation. The primary purpose of this study is to determine whether we can shift self-regulation for the ultimate goal (in Aim 4) of targeting self-regulation to impact health behaviors.

---|---|
Experimental: Laddr
All participants in the study will be invited to use Laddr, described in the intervention section.
|
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.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
12-item Momentary Self-regulation Questionnaire
Time Frame: 14 days
|
Self-reported momentary self-regulation assessed by the momentary self-regulation questionnaire four times daily (morning, early afternoon, late afternoon/evening, and night) over a 14-day period.
Each item is scored 1 (not at all) to 5 (extremely).
The scale is comprised of four subscales: momentary perseverance, momentary sensation seeking, momentary self-judgment, and momentary mindfulness.
Each subscale score is calculated by averaging the responses from three of the scale items.
Scores on each subscale range from 1 to 5, with higher subscale scores indicating greater momentary reporting of that facet of self-regulation (perseverance, sensation seeking, self-judgment, or mindfulness).

Time Frame |
---|---|---|
Binge Eating Episodes [Binge Eating Sample Only]
Time Frame: 14 days
|
[Binge eating sample only] Self-reported binge eating episodes assessed four times daily (morning, early afternoon, late afternoon/evening, and night) over a 14-day period.
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).
Loss of control is assessed by the question "When you ate most recently, did you lose control over your eating?" and is scored as 1 (not at all) to 5 (totally), where a 4 or 5 is considered loss of control.

Smoking Episodes [Smoking Sample Only]
Time Frame: 14 days
|
[Smoking sample only] Self-reported smoking assessed four times daily (morning, early afternoon, late afternoon/evening, and night) over a 14-day period.
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.
