Theim, Kelly R.; Sinton, Meghan M.; Stein, Richard I.; Saelens, Brian E.; Thekkedam, Sucheta C.; Welch, R. Robinson; Epstein, Leonard H.; Wilfley, Denise E. – Journal of Youth and Adolescence, 2012
Developmentally relevant high-risk dietary situations (e.g., parties where tempting foods are available) may influence overweight youth's weight control, as they increase risk for overeating. Better self-efficacy for coping with these situations--which preadolescents may learn from their parents--could foster successful weight control. Overweight…

Sinton, Meghan M.; Goldschmidt, Andrea B.; Aspen, Vandana; Theim, Kelly R.; Stein, Richard I.; Saelens, Brian E.; Epstein, Leonard H.; Wilfley, Denise E. – Journal of Youth and Adolescence, 2012
Shape and weight concerns among overweight pre-adolescents heighten risk for eating disorders and weight gain. Treatment and prevention efforts require consideration of psychosocial factors that co-occur with these concerns. This study involved 200 overweight pre-adolescents, aged 7-12 years (M age = 9.8; SD = 1.4), presenting for family-based…

Epstein, Leonard H.; Temple, Jennifer L.; Roemmich, James N.; Bouton, Mark E. – Psychological Review, 2009
Research has shown that animals and humans habituate on a variety of behavioral and physiological responses to repeated presentations of food cues, and habituation is related to amount of food consumed and cessation of eating. The purpose of this article is to provide an overview of experimental paradigms used to study habituation, integrate a…

Epstein, Leonard H.; Robinson, Jodie L.; Temple, Jennifer L.; Roemmich, James N.; Marusewski, Angela; Nadbrzuch, Rachel – Learning and Motivation, 2008
The rate of habituation to food is inversely related to energy intake, and overweight children may habituate slower to food and consume more energy. This study compared patterns of sensitization, as defined by an initial increase in operant or motivated responding for food, and habituation, defined by gradual reduction in responding, for macaroni…

Epstein, Leonard H.; Leddy, John J.; Temple, Jennifer L.; Faith, Myles S. – Psychological Bulletin, 2007
Eating represents a choice among many alternative behaviors. The purpose of this review is to provide an overview of how food reinforcement and behavioral choice theory are related to eating and to show how this theoretical approach may help organize research on eating from molecular genetics through treatment and prevention of obesity. Special…
