A Pilot Test of Mood and Circadian Rhythm Mechanisms Driving Binge Eating
Eating DisorderBinge Eating1 moreMood and circadian rhythm disruptions are associated with binge eating (BE). BE is a discrete, episodic behavior characterized by 1) eating an objectively large amount of food and 2) experiencing a subjective sense of loss of control. BE episodes are often preceded by negative mood states, and a subtype of individuals with BE has high levels of negative moods. This group has more comorbid psychopathology and a poorer response to treatment. Thus, understanding the role of negative mood is a critical area for research on BE. Individuals with BE demonstrate disruptions in several circadian rhythms, including diurnal meal timing, hormone patterns (e.g., daily cortisol rhythms), and mood variations. The most potent synchronizer of circadian rhythms is light. Thus, exposure to light may explain other phenomena that fluctuate similarly, such as mood and the occurrence of BE. Mood is subject to the influence of light, and BE is also influenced by exposure to bright light. It is unknown whether regulating circadian rhythms via regular exposure to light improves BE through its effects on mood or via changes in other biological or behavioral rhythms. This knowledge can inform the development of treatments targeting biobehavioral mechanisms that maintain BE and indicate for whom this may be most effective. This project aims to test the roles of negative mood and circadian rhythms in the relationship between light exposure and BE and identify subtypes of individuals in whom this effect is strong. The investigators hypothesize that individuals exposed to less natural bright light will experience more frequent BE, more negative mood, and a blunted morning cortisol response. The investigators further hypothesize that manipulating exposure to artificial bright light will reduce the frequency of BE and negative mood and increase the morning cortisol response. Finally, the investigators hypothesize that the effects of this artificial bright light exposure on BE frequency will be mediated by changes in negative mood, which itself will be accounted for by changes in circadian rhythms as indicated by the morning cortisol response. Additionally, the investigators have two moderation hypotheses: that the effects of artificial bright light exposure on BE will be greater for those who fit the high negative mood type than those who do not and that the effects will be greater for individuals with a blunted morning cortisol response at baseline than for those without.

Ameliorating Cognitive Control in Binge Eating Disorder
Binge-Eating DisorderThere is evidence that impairment of impulse regulation is involved in the development and maintenance of eating disorders, especially in Binge Eating Disorder (BED). BED is characterized by recurrent episodes of binge eating with experienced loss of control over eating. Controlling impulsive behaviour, cognitive flexibility, planning and decision making are key abilities of impulse regulation. Some of these impaired cognitive functions are linked to decreased activity of certain brain regions. Transcranial direct current stimulation (tDCS) is a well-established method to alter brain activity. In the current project, we explore if a computer-assisted training programme for patients with BED that is combined with tDCS is feasible and able to ameliorate impulse regulation and impulsive eating behaviour. We hypothesize that the cognitive training programme with additional tDCS will result in a greater decrease of BED symptoms and a stronger increase in impulse regulation skills compared with the cognitive training programme without tDCS by using a placebo stimulation.

Dialectical Behavior Therapy Guided Self-Help for Binge Eating Disorder
Binge Eating DisorderThis study will compare unguided and guided dialectical behavior therapy (DBT) self-help to an attention-placebo self-help control condition. Participants with binge eating disorder will be randomly assigned to one of the three self-help conditions for 12 weeks. Six guided self-help sessions will take place via secure video-calling. Assessments will take place before, mid-way through, and after the self-help program as well as at 3-month follow-up. Six guided self-help sessions will take place via secure video-calling.

Optimizing a Smartphone Application for Individuals With Eating Disorders
Eating DisordersBinge Eating Disorder1 moreThis study will augment an existing mobile application for individuals with eating disorders by developing adaptive, tailored content targeting remediation of cognitive distortions. The adaptive application will be deployed and assessed for efficacy relative to the standard product in a randomized controlled trial.

Vortioxetine for Binge Eating Disorder
Binge Eating DisorderThe aim of the present study is to examine the efficacy and safety of vortioxetine vs placebo in adults with moderate to severe Binge eating disorder, as indicated by at least 3 binge eating days per week for the 2 weeks before the baseline visit.

Phentermine/Topiramate Extended Release in Binge Eating Disorder (BED)
Binge Eating DisorderThe goal of this project is to evaluate the effectiveness and tolerability of the novel weight management medication PHEN/TPM ER (Qsymia®)along with nutritional and lifestyle modification counseling in the treatment of binge eating disorder (BED) in overweight or obese individuals.

Behavioral and Pharmacologic Treatment of Binge Eating and Obesity: Acute Treatment
Binge-eating DisorderObesityThis study will test the effectiveness and relative efficacy of behavioral and pharmacologic treatments, alone and in combination, for the treatment of binge eating disorder (BED) in patients with obesity. This is an acute treatment comparing behavioral weight loss alone or in combination with naltrexone/bupropion medication.

Open Label Extension in Adults With Binge Eating Disorder (BED)

Binge Eating Disorder Treatment Study
Binge Eating DisorderThe main objective of the proposed study is to determine whether the effectiveness of a group therapy treatment for Binge Eating Disorder (BED) is improved and attrition reduced by optimally matching women with BED who have high attachment anxiety to Group Psychodynamic Interpersonal Psychotherapy (GPIP). This study represents the next phase in a program of research stemming from a previously conducted randomized controlled trial (RCT).
