relation of Dietary Restraint scores to activation of reward related brain regions in response to food intake anticipated intake and food pictures
NeuroImage, 2011Co-Authors: Kyle S. Burger, Eric SticeAbstract:Prospective studies indicate that individuals with elevated Dietary Restraint scores are at increased risk for future bulimic symptom onset, suggesting that these individuals may show hyper-responsivity of reward regions to food and food cues. Thus, we used functional magnetic resonance imaging (fMRI) to examine the relation of Dietary Restraint scores to activation of reward-related brain regions in response to receipt and anticipated receipt of chocolate milkshake and exposure to pictures of appetizing foods in 39 female adolescents (mean age = 15.5 ± 0.94). Dietary Restraint scores were positively correlated with activation in the right orbitofrontal cortex (OFC) and bilateral dorsolateral prefrontal cortex (DLPFC) in response to milkshake receipt. However, Dietary Restraint scores did not correlate with activation in response to anticipated milkshake receipt or exposure to food pictures. Results indicate that individuals who report high Dietary Restraint have a hyper-responsivity in reward-related brain regions when food intake is occurring, which may increase risk for overeating and binge eating.

relation of Dietary Restraint scores to cognitive biases and reward sensitivity
Appetite, 2010Co-Authors: Matt Field, Amy L Ahern, Sonja Yokum, Cara Bohon, Eric SticeAbstract:Abstract This study tested the hypotheses that Dietary Restraint scores are associated with greater reward sensitivity and cognitive bias for food-related cues, which might result in chronic overeating and efforts to curb this tendency through Dietary restriction. Participants ( N = 63) with high versus low scores on the DEBQ-R did not differ on attentional bias for pictorial food-related cues on a visual probe task, or approach tendencies elicited by food cues, as assessed with a stimulus–response compatibility (SRC) task. Restraint was also unrelated to performance on an operant task that assessed how hard participants would work for snacks, or responding during a taste habituation paradigm. Dietary Restraint scores were correlated with self-reported appetitive response to food, sensitivity to reward, and sensitivity to punishment. Results provide limited support for the hypothesis that individuals with elevated Dietary Restraint scores show greater reward sensitivity and cognitive bias for food stimuli, though it is possible that the null findings on the behavioral task resulted because of an approach-avoidance conflict to food cues in which heightened appetitive responses to food are inhibited by food-related anxiety.

are Dietary Restraint scales valid measures of Dietary restriction additional objective behavioral and biological data suggest not
Appetite, 2010Co-Authors: Eric Stice, Robyn Sysko, Christina A Roberto, Shelley AllisonAbstract:Abstract Prospective studies find that individuals with elevated Dietary Restraint scores are at increased risk for bulimic symptom onset, yet experiments find that assignment to energy-deficit diet interventions reduce bulimic symptoms. One explanation for the conflicting findings is that the Dietary Restraint scales used in the former studies do not actually identify individuals who are restraining their caloric intake. Thus, we tested whether Dietary Restraint scales showed inverse relations to objectively measured caloric intake in three studies. Four Dietary Restraint scales did not correlate with doubly labeled water estimates of caloric intake over a 2-week period ( M , r = .01). One scale showed a significant inverse correlation with objectively measured caloric intake during a regular meal ordered from an ecologically valid menu ( M , r = −.30), but a significant positive relation that was qualified by a significant quadratic effect, to objectively measured caloric intake during multiple eating episodes in the lab ( M , r = .32). In balance, results suggest that Dietary Restraint scales are not valid measures of Dietary restriction, replicating findings from prior studies that examined objective measures of caloric intake.

are Dietary Restraint scales valid measures of moderate to long term Dietary restriction objective biological and behavioral data suggest not
Psychological Assessment, 2007Co-Authors: Eric Stice, Jamie A Cooper, Dale A Schoeller, Karyn A Tappe, Michael R LoweAbstract:Prospective studies indicate that elevated scores on Dietary Restraint scales predict bulimic symptom onset, but experiments indicate that assignment to Dietary restriction interventions reduces bulimic symptoms. One possible explanation for the inconsistent findings is that the Dietary Restraint scales used in the former studies are not valid measures of Dietary restriction. The authors previously found that Dietary Restraint scales were not inversely correlated with objective measures of short-term caloric intake (E. Stice, M. Fisher, & M. R. Lowe, 2004). In this follow-up report, 3 studies indicated that the Three-Factor Eating Questionnaire Dietary Restraint scale was not correlated with doubly labeled water estimated energy intake over 2-week periods or with observationally measured caloric intake over 3 months. Results from this study and others suggest that Dietary Restraint scales may not be valid measures of moderate- to long-term Dietary restriction and imply the need to reinterpret findings from studies that have used Dietary Restraint scales.

Dietary Restraint and body mass change a 3 year follow up study in a representative dutch sample
Appetite, 2014Co-Authors: Tatjana Van Strien, Peter C Herman, M W VerheijdenAbstract:Abstract Objective: To determine in a representative Dutch sample the association of Dietary Restraint, Concern for Dieting, and Weight Fluctuation with subsequent change in body mass index (BMI; in kg/m 2 ) in addition to possible moderator effects of sex, level of education, age category, ethnicity, overweight level and physical activity. Design: In a longitudinal study in a representative Dutch sample consisting of 675 participants (331 females, 344 males), Dietary Restraint (including Concern for Dieting and Weight Fluctuation) was assessed with the Restraint Scale at baseline, and also self-reported weight and height. Three years later, weight and height were also assessed. Results: Dietary Restraint was significantly associated with an increase in BMI after three years ( B = .272, p = 001). Inspection of the significant moderator effect of sex ( B = −.387, p = .012) indicated that Dietary Restraint was significantly associated with increases in BMI only in females. There was no main effect for Concern for Dieting ( p = .091). There was a moderator effect of sex on the association between Concern for Dieting and BMI change ( B = −.424; p = .002): initial concern for dieting was positively associated with subsequent body mass gain only in women. Weight Fluctuation was significantly associated with an increase in BMI after three years ( B = .162, p = 008) and sex did not moderate this association. There were no moderator effects for level of education, age category, ethnicity, overweight level and physical activity. Conclusion: Dietary Restraint and Concern for Dieting are associated with increases in BMI only in females. Weight Fluctuation is associated with increases in BMI in both males and females.

Dietary Restraint intention versus behavior to restrict food intake
Appetite, 2007Co-Authors: Junilla K Larsen, Tatjana Van Strien, Peter C Herman, Rob Eisinga, Rutger C M E EngelsAbstract:The Dutch Eating Behavior Questionnaire Restraint Scale (DEBQ-R) assesses both intentions to restrict food intake (3 items) and actual behavioral Restraint (7 items). Studies in general population's samples have shown that the DEBQ-R is a reliable instrument with all items loading highly on a single factor. The purpose of the present study was to examine the psychometric properties of a two-factor intention-versus-behavior structure of the DEBQ-R in 3 different weight-concerned samples with people from different (over)weight categories (total N=790) using confirmatory factor analysis. A robust two-factor structure emerged in the various samples, generally supporting a distinction between DEBQ-R questions relating to intentions to restrict food intake and actual restrictive behavior. Results obtained in this study are important, because they suggest that a distinction between restrained intention and behavior could help to explain the relation between Dietary Restraint and external overeating tendencies. Future longitudinal research should examine whether the newly developed Dietary Restraint scales predict changes in overeating and Body Mass Index (BMI).

relations between Dietary Restraint depressive symptoms and binge eating a longitudinal study
International Journal of Eating Disorders, 2006Co-Authors: Sonja T P Spoor, Eric Stice, Marrie H J Bekker, Tatjana Van Strien, Marcel A Croon, Guus L Van HeckAbstract:Objective: Temporal relations between Dietary Restraint, depressive symptoms, and binge eating were tested by means of three competing models positing that (1) Dietary Restraint and depressive symptoms predict future increases in binge eating, (2) binge eating predicts future increases in Dietary Restraint and depressive symptoms, and (3) binge eating is reciprocally related to these two factors. Method: Longitudinal data from a community sample of Dutch females (N = 143; M age = 19.6) was used to test these relations while controlling for initial levels of these factors. Results: Dietary Restraint did not predict future increases in binge eating, nor did binge eating predict future increases in Dietary Restraint. Depressive symptoms predicted future increases in binge eating, but binge eating did not predict future increases in depressive symptoms. Conclusion: Although this study had limited statistical power, the pattern of relations and effect sizes suggest that depressive symptoms, but not Dietary Restraint, increase risk of binge eating for late adolescent females. © 2006 by Wiley Periodicals, Inc.

the validity of Dietary Restraint scales comment on stice et al 2004
Psychological Assessment, 2006Co-Authors: Tatjana Van Strien, Rutger C M E Engels, Wija A Van Staveren, Peter C HermanAbstract:In 4 empirical studies, E. Stice, M. Fisher, and M. R. Lowe (2004) calculated the correlations between some widely used Dietary Restraint scales and food intake. Failing to find substantial negative correlations, they concluded that these scales were invalid. The current article challenges this conclusion. For one thing, there is some evidence that restrained eaters do eat less than do unrestrained eaters under controlled experimental conditions favoring self-control. Dietary Restraint is also associated with tendencies toward disinhibition under conditions favoring lose. of self-control; such disinhibition often masks (but does not invalidate) the construct of Dietary Restraint. For these and other reasons, the assessment of food intake at a single eating episode may not capture overall Dietary restriction. Finally, how much one eats does not necessarily indicate whether one has eaten less than one desired to eat. The authors suggest that the existing Restraint scales do in fact validly assess restriction of food intake, albeit in a more complex fashion than is evident from simple correlations in single episodes.

the moderating role of negative urgency on the associations between affect Dietary Restraint and calorie intake an experimental study
Personality and Individual Differences, 2014Co-Authors: Rebecca L Emery, Kevin M King, Michele D. LevineAbstract:Abstract The present study tested the moderating role of negative urgency (NU), a personality trait characterized by a tendency to act impulsively in the face of emotional distress, on the associations between Dietary Restraint, affect, and calorie intake following a mood manipulation. Undergraduate women reported levels of NU and Dietary Restraint and underwent a failure task intended to induce a negative mood. Participants then completed mood ratings and a sham taste assessment task in which calorie intake was measured. NU enhanced the association between Dietary Restraint and calorie intake, such that participants who reported higher levels of Dietary Restraint consumed more calories, and this effect was strongest among participants who were high on NU. NU also enhanced the association between positive, but not negative, affect and calorie intake. Specifically, participants who were high on NU and reported lower positive affect consumed more calories than participants who were low on NU. These findings suggest that NU plays a synergistic role in increasing calorie intake among individuals who engage in Dietary Restraint or experience low positive affect.

the moderating role of negative urgency on the prospective association between Dietary Restraint and binge eating
Appetite, 2013Co-Authors: Rebecca L Emery, Kevin M King, Sarah Fischer, Kendra R DavisAbstract:Abstract It is well documented that negative urgency, a personality trait characterized by a tendency to act impulsively in the face of negative emotions, and Dietary Restraint independently increase risk to binge eat; however, it is unclear how these factors interact to alter risk for such behavior. It may be that individuals high on negative urgency, who also engage in Dietary Restraint, are at a greater risk to binge eat than individuals low on negative urgency. Accordingly, we sought to investigate whether negative urgency moderated the prospective association between Dietary Restraint and binge eating frequency among a sample of college women. We hypothesized that women who engaged in Dietary Restraint would report higher binge eating frequencies across the first semester of college and that this effect would be strengthened among individuals higher on negative urgency. Results indicated that negative urgency moderated the prospective association between Dietary Restraint and binge eating frequency. This effect was found to be “protective but reactive,” such that low levels of Dietary Restraint protected against binge eating frequency at low to moderate levels of negative urgency, but this buffering effect was lost at high levels of negative urgency where binge eating frequency was equal across all levels of Dietary Restraint. These findings demonstrate that negative urgency and Dietary Restraint interact to differentially alter risk for binge eating frequency, and individuals high on negative urgency are at the greatest risk to engage in more frequent binge eating regardless of level of Dietary Restraint.

intrinsic brain subsystem associated with Dietary Restraint disinhibition and hunger an fmri study
Brain Imaging and Behavior, 2017Co-Authors: Jizheng Zhao, Mintong Li, Yi Zhang, Huaibo Song, Karen M Von Deneen, Dongjian HeAbstract:Eating behaviors are closely related to body weight, and eating traits are depicted in three dimensions: Dietary Restraint, disinhibition, and hunger. The current study aims to explore whether these aspects of eating behaviors are related to intrinsic brain activation, and to further investigate the relationship between the brain activation relating to these eating traits and body weight, as well as the link between function connectivity (FC) of the correlative brain regions and body weight. Our results demonstrated positive associations between Dietary Restraint and baseline activation of the frontal and the temporal regions (i.e., food reward encoding) and the limbic regions (i.e., homeostatic control, including the hypothalamus). Disinhibition was positively associated with the activation of the frontal motivational system (i.e., OFC) and the premotor cortex. Hunger was positively related to extensive activations in the prefrontal, temporal, and limbic, as well as in the cerebellum. Within the brain regions relating to Dietary Restraint, weight status was negatively correlated with FC of the left middle temporal gyrus and left inferior temporal gyrus, and was positively associated with the FC of regions in the anterior temporal gyrus and fusiform visual cortex. Weight status was positively associated with the FC within regions in the prefrontal motor cortex and the right ACC serving inhibition, and was negatively related with the FC of regions in the frontal cortical-basal ganglia-thalamic circuits responding to hunger control. Our data depicted an association between intrinsic brain activation and Dietary Restraint, disinhibition, and hunger, and presented the links of their activations and FCs with weight status.
