AbstractA 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.
Idiosyncratic variables affecting functional analysis outcomes: A review (2001-2010)Schlichenmeyer, Kevin J.; Roscoe, Eileen M.; Rooker, Griffin W.; Wheeler, Emily E.; Dube, William V. (2013-02-20)Although typical functional analyses often produce clear outcomes, some studies have reported ambiguous results that cannot be interpreted. Such undifferentiated outcomes may occur if test conditions do not include relevant antecedent or consequent events. Clinicians then may try to modify the functional analysis conditions to include those events. Hanley, Iwata, and McCord (2003) reviewed the functional analysis literature through the year 2000 and described idiosyncratic variables included in modified functional analyses. The objective of the present review was to present a quantitative analysis of idiosyncratic antecedents and consequences in modified functional analyses during the past decade (2001 to 2010). We discuss the range of stimulus parameters tested and the assessment strategies used for informing the modified analysis conditions.
