“…Impulsivity is not a unidimensional concept itself, so different modalities of measurement (e.g., self-report versus objective behavioural tasks) may assess different aspects of inhibitory control ( Dawe and Loxton, 2004 ; Giel et al, 2017 ). The proposed ‘trait versus state dichotomy of impulsivity’ ( Yeo et al, 2020 ) suggests that self-report measures, like the BIS-11, capture a more trait-like representation of impulsivity, while behavioural tasks may be more dependent on state-dependent factors, such as stress. Further, neuroimaging research from children with ADHD shows that psychostimulants may be most effective at ameliorating aberrances in reward and inhibitory control circuits ( Solanto, 1998 ), which are more likely to present as changes in trait-like impulsivity than environmentally-induced state factors.…”

Impulsivity and Its Relationship With Lisdexamfetamine Dimesylate Treatment in Binge Eating Disorder

et al. 2021

High trait impulsivity is thought to contribute to the sense of loss of control over eating and impulses to binge eat experienced by those with binge eating disorder (BED). Lisdexamfetamine dimesylate (LDX), a drug approved for treatment of moderate to severe BED, has been shown to decrease impulsive features of BED. However, the relationship between LDX-related reductions of binge eating (BE) episodes and impulsivity has not yet been explored. Forty-one adults aged 18–40years with moderate to severe BED completed questionnaires and tasks assessing impulsivity at baseline and after 8weeks of 50–70mg of LDX. Twenty age-matched healthy controls were also assessed at two timepoints for normative comparison. Data were analysed using linear mixed models. BED participants exhibited increased self-reported motor, non-planning, cognitive and food-related impulsivity relative to controls but no differences in objective task-based measures of impulsivity. Food-related and non-planning impulsivity was significantly reduced by LDX, but not to normative levels. Individuals with higher baseline levels of motor and non-planning impulsivity, and loss of control over eating scores experienced the greatest reduction in BE frequency after 8weeks of LDX. Further, there were significant associations between the degree to which subjective loss of control over eating, non-planning impulsivity and BE frequency reduced after 8weeks of LDX. These data suggest that specific subjective measures of impulsivity may be able to predict who will have the greatest benefit from LDX treatment and that reductions in BE frequency may be moderated by concurrent reductions in non-planning impulsivity.

“…More recently, a third domain of impulsivity characterised as the ‘impulsive personality trait’ relates to the persisting underlying tendency to behave impulsively ( MacKillop et al, 2016 ). This differs from ‘state impulsivity’, which can be modulated by external influences ( Yeo et al, 2020 ).…”

“…In association, negative urgency-the tendency to act impulsively in the face of negative emotions-seems to be in close relation with uncontrolled eating [7,8]. Individuals with higher levels of negative urgency are at greater risk of engaging in more frequent binge-eating [9].…”

Excess skin and disordered eating behaviors are referred to as some of the major negative consequences of bariatric surgery as well as body image shame. This study sought to explore how discomfort with excessive skin, body image shame, psychological distress, eating-related psychopathology, and negative urgency interact to understand uncontrolled eating among woman submitted to bariatric surgery. A cross-sectional sample of 137 women was evaluated postoperatively through self-report questionnaires assessing discomfort with excess skin, body image shame, eating-related psychopathology, negative urgency, and uncontrolled eating in a hospital center in the north of Portugal. Pearson correlations and Structural Equation Modeling (SEM) were performed. Body image shame mediated the relationship between discomfort with excess skin and eating-related psychopathology. In turn, the relationship between eating-related psychopathology and uncontrolled eating was mediated by negative urgency. This study highlights the impact of excess skin and body image shame on eating behavior post-bariatric-surgery. Considering the proven impact of uncontrolled eating on weight-loss results post-surgery, understanding the mechanisms underlying this problem is highly important. Our findings provide helpful insight for multidisciplinary teams committed to providing care to bariatric patients struggling with body image and eating difficulties.

“…In the long run, concerns of DM relapse [18], inadequate weight loss, or weight regain also need to be addressed [19]. Studies have shown that elevated levels of distress secondary to COVID-19 can lead to emotional dysregulation, leading to increased impulsivity and binge eating symptoms before and after bariatric surgery [20,21].…”
