Brief Summary

The objective of this study is to determine the relations among food insecurity status, obesity, and impulsive food choice patterns and to test the extent to which a mindful eating strategy reduces impulsive choice for food. The central hypothesis is that food-insecure individuals will demonstrate more impulsive food choice patterns and demonstrate a greater likelihood of obesity than individuals who are food secure. Two specific aims are proposed: Specific aim #1: Determine the relation between food insecurity, obesity, and impulsive food choice patterns in women. The working hypothesis is that food-insecure individuals, especially those that are obese, will exhibit more impulsive food choice patterns than food-secure individuals. Specific aim #2: Determine the efficacy of an extended mindfulness-based eating strategy on impulsive choice patterns among food insecure women. The working hypothesis is that mindful eating will reduce impulsive food choice patterns relative to baseline and control conditions, and will persist to follow-up. The investigators expect mindful eating to reduce impulsive choice compared to control conditions, despite food security status.

Conditions

Feeding Behavior; Obesity; Impulsivity

Mindfulness; Obesity; Food insecurity; Delay discounting

Outcome Measures

Primary Outcomes (2)

• Number of impulsive choices as assessed by the Food Choice Questionnaire

  Participants will be asked to make a series of hypothetical choices between small, sooner (impulsive) vs. larger, later (self controlled) hypothetical food-related outcomes

  Two to three weeks

• Number of impulsive choices as assessed by the Monetary Choice Questionnaire

  Participants will be asked to make a series of hypothetical choices between small, sooner (impulsive) vs. larger, later (self controlled) hypothetical monetary outcomes

  Two to three weeks

Study Arms (3)

Mindful Eating

EXPERIMENTAL

Participants in this arm will receive a 50 min mindful eating training with four pieces of food. They will practice mindful eating at home with two meals for a one-week duration.

Behavioral: Mindful Eating

Nutrition Digital Video Disc (DVD)

ACTIVE COMPARATOR

Participants will watch a 50 min DVD on nutrition and receive four pieces of food. They will receive prompts twice a week to give one-word answers to questions about food.

Other: Nutrition DVD

Control

NO INTERVENTION

Participants will receive four pieces of food. They will not receive any prompts during the one week.

Interventions

Mindful Eating BEHAVIORAL

Mindful eating is a behavioral strategy in which food is eaten slowly, with deliberate and focused attention on the features of food, the process of eating, and physiological responses to eating. Objectivity is key.

Also known as: Raisin exercise

Mindful Eating

Nutrition DVD OTHER

Participants watch a 50 minute video on nutrition to control for verbal aspects of food.
