AbstractRATIONALE: The long-rejected construct of food addiction is undergoing re-examination. OBJECTIVES: To evaluate whether a novel carbohydrate food shows abuse potential for rigorously defined carbohydrate cravers, as evidenced by selective self-administration and mood enhancement during double-blind discrimination testing. MATERIALS AND METHODS: Discrete trials choice testing was performed with 61 overweight (BMI m = 27.64, SD = 2.59) women (ages 18-45; 19.70% African American) whose diet records showed >4 weekly afternoon/evening emotional-eating episodes confined to snacks with carbohydrate to protein ratio of >6:1. After being induced into a sad mood, participants were exposed, double-blind and in counterbalanced order, to taste-matched carbohydrate and protein beverages. They were asked to choose and self-administer the drink that made them feel better. RESULTS: Women overwhelmingly chose the carbohydrate beverage, even though blinded. Mixed-effects regression modeling, controlling for beverage order, revealed greater liking and greater reduction in dysphoria after administration of the carbohydrate beverage compared to the protein beverage but no differential effect on vigor. CONCLUSION: For women who crave them, carbohydrates appear to display abuse potential, plausibly contributing to overconsumption and overweight.

Delay discounting and intake of ready-to-eat and away-from-home foods in overweight and obese womenAppelhans, Bradley M.; Waring, Molly E.; Schneider, Kristin L.; Pagoto, Sherry L.; DeBiasse, Michele A.; Whited, Matthew C.; Lynch, Elizabeth B. (2012-10-01)A shift from home-prepared to away-from-home and ready-to-eat foods has occurred in recent decades, which has implications for obesity and health. This study tested whether delay discounting, a facet of impulsivity reflecting sensitivity to immediate reward, is associated with the frequency of consumption and typical amount consumed of home-prepared, away-from-home, and ready-to-eat foods among overweight and obese women. Seventy-eight participants completed a binary choice task assessing discounting of delayed monetary rewards. Nutrient analysis of weighed food records characterized dietary intake over seven consecutive days. Foods were categorized as home-prepared, away-from-home, or ready-to-eat by a registered dietitian from information provided by participants. Delay discounting was not associated with the frequency of consuming home-prepared, away-from-home, and ready-to-eat foods as reflected in the percentages of recorded foods or total energy intake from each category. However, once consuming away-from-home and ready-to-eat foods (but not home-prepared foods), impulsive women consumed more energy than less impulsive women. Exploratory analyses indicated that more impulsive women chose away-from-home foods with a higher energy density (kcal/g). Impulsivity was associated with the quantity of away-from-home and ready-to-eat foods consumed, but not the frequency of their consumption. Home food preparation may be critical to weight control for impulsive individuals.
The contribution of school environmental factors to individual and school variation in disordered weight control behaviors in a statewide sample of middle schoolsAustin, S. Bryn; Richmond, Tracy K.; Spadano-Gasbarro, Jennifer L.; Greaney, Mary L.; Blood, Emily A.; Walls, Courtney E.; Wang, Monica L.; Mezgebu, Solomon; Osganian, Stavroula K.; Peterson, Karen E. (2013-02-19)We investigated the contribution of school environmental factors to individual and school variation in disordered weight control behaviors (DWCB). Analyses were based on self-report data gathered from 18,567 middle-school students in 2005 and publicly available data on school characteristics. We observed large differences across schools in percent of students engaging in DWCB in the past month, ranging from less than 1% of the student body to 12%. School-neighborhood poverty was associated with higher odds of DWCB in boys. Preventive strategies need to account for wide variability across schools and environmental factors that may contribute to DWCB in early adolescence.
Discovering Behavioral Intervention: A Parent’s Interactive Guide to ABAFleming, Richard K.; Curtin, Carol; Gray, Cheryl A.; Hamad, Charles D. (2014-01-01)Autism spectrum disorders (ASD) affect one in 110 children in the U.S. Parents of children with ASD need clear and accurate information to communicate with professionals as they seek appropriate services, including applied behavior analysis (ABA) based intervention. Behavioral professionals can assist parents in this endeavor by recommending resources, including online courses. This paper describes the development and evaluation of an online course on ABA for parents of children with ASD. Parents completing a summative field test (N=21) made significant gains in knowledge and reported high levels of satisfaction. Implications include the potential for enhanced parent-professional collaboration in treatment decision-making.
