“…While the results were in the direction predicted on the basis of previous research (e.g. Decker et al, ; Kekic et al, ; Manwaring et al, ; Steinglass et al, ), none of the ED groups showed differences in TD or self‐reported tendency to delay gratification compared with HC. It is possible that the number of participants within each of the groups in the present study may have been insufficient to detect differences, although it is of note that null findings have been reported (e.g.…”

“…In such tasks, TD is reflected by a preference for smaller rewards received sooner than larger delayed rewards and is proposed to reflect choice impulsivity and poor reward‐related inhibitory control (Bari & Robbins, ). Studies in EDs have reported that compared with healthy adults, those with bulimia nervosa (BN; Kekic et al, ) and BED (Davis, Patte, Curtis, & Reid, ; Manasse, Espel, et al, ; Manasse, Forman, et al, ; Manwaring, Green, Myerson, Strube, & Wilfley, ; Mole et al, ) show greater TD (i.e. a preference for smaller‐sooner rewards), whereas the opposite has been reported in studies of adults with AN (Decker, Figner, & Steinglass, ; Steinglass et al, ).…”

Bulimia nervosa (BN) and binge eating disorder (BED) have been associated with poorer rewardrelated inhibitory control, reflected by a reduced tendency to delay gratification. The opposite has been reported in anorexia nervosa (AN), but differences have not been directly compared across eating disorders (EDs). This study investigated self-reported (delaying gratification inventory) and task-based (temporal discounting) inhibitory control in 66 women with an ED and 28 healthy controls (HC). Poorer task-based inhibitory control was observed in the BN compared to the AN group, and poorer self-reported inhibitory control in the BN and BED groups compared to the AN and HC groups, suggesting that reward-related inhibitory control varies across EDs. Symptom severity correlated with poorer self-reported (but not task-based) inhibitory control across the EDs. These data provide some support for transdiagnostic mechanisms, and highlight the importance of addressing perceived loss of control in the treatment of EDs.

“…Consistent with affect regulation models of BN and binge eating (Hawkins and Clement, 1984; Heatherton and Baumeister, 1991; Hohlstein et al, 1998), our findings suggest that reduced likelihood of extreme increases in NA (i.e., PAC) could function to provide short-term reinforcement of bulimic behaviors; however, our findings also suggest that these behaviors are ineffective in terms of promoting ongoing emotional stability (i.e., MSSD). BN is associated with a preference for smaller-sooner rewards (Kekic et al, 2016), and recurrent binge eating and purging despite significant longer-term negative repercussions may reflect alterations in reward-based learning in BN (Berner and Marsh, 2014; Frank et al, 2011). Individuals with BN also may overvalue the immediate rewards of reduced NA intensity and reduced likelihood of an extreme NA increase after bulimic behaviors, while undervaluing the negative outcome of increased average NA instability.…”

Prior research suggests that the construct of emotional instability may be salient to bulimia nervosa (BN), but no study to date has used ecological momentary assessment (EMA) to examine its temporal association with binge eating and purging. In the current study, 133 women with DSM-IV BN used portable digital devices to provide multiple daily negative affect (NA) and positive affect (PA) ratings and record eating disorder behaviors over 2 weeks. Two state-of-the art indices quantified affective instability: probability of acute change (PAC), which represents the likelihood of extreme affective increases, and mean squared successive difference (MSSD), which represents average change over successive recordings. For extreme affective change, results revealed that on bulimic behavior days, extreme NA increases were less likely after bulimic behaviors than before them, and extreme increases in PA were more likely after bulimic behaviors than during the same time period on non-bulimic behavior days. However, average NA instability (i.e., MSSD) was (a) greater on bulimic behavior days than non-bulimic behavior days, (b) greater after bulimic behaviors than during the same time period on non-bulimic behavior days, and (c) greater after bulimic behaviors than before them. Results lend support to the notion that bulimic behaviors are negatively reinforcing (i.e., via post-behavior acute affective changes), but also indicate that these behaviors may exacerbate overall affective dysregulation. These findings may improve understanding of BN maintenance and inform the development of novel interventions or refinement of existing treatments.

“…Moreover, impairments in decision making are associated with BN compared to HCs. For example, a study investigating temporal discounting found that adults with BN placed less value on future rewards than HCs, a characteristic which may make them more susceptible to binge eating (21). Another study examined executive function (composite Z-score combining measures of set-shifting, problem solving and inhibition) in those diagnosed with BN or AN and compared them to HCs.…”

Purpose of Review Recent research has highlighted executive function and neurocognitive deficits among individuals with eating and weight disorders, identifying a potential target for treatment. Treatments targeting executive function for eating and weight disorders are emerging. This review aims to summarize the recent literature evaluating neurocognitive/executive function-oriented treatments for eating and weight disorders and highlights additional work needed in this area. Recent Findings Cognitive remediation therapy (CRT) for anorexia nervosa has been the most extensively studied neurocognitive treatment for eating disorders. Results demonstrate that CRT improves executive function and may aid in the reduction of eating disorder symptomatology. Computer training programs targeting modifying attention and increasing inhibition are targeting reduction of binge eating and weight loss with modest success. Summary Neurocognitive treatments are emerging and show initial promise for eating and weight disorders. Further research is necessary to determine whether these treatments can be used as stand-alone treatments or whether they need to be used as an adjunct to or in conjunction with other evidence-based treatments to improve outcomes.
