Filter by:The purpose of this proposed project is to test whether several biological factors (such as elevated brain reward region and attention region response to high-calorie foods, weaker inhibitory region response to high-calorie foods, habitual caloric deprivation, and elevated limbic region responsivity) increase the risk of problematic eating (bingeing and purging) in female adolescents.
Mood 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.
The study seeks to evaluate the acceptability, feasibility, target engagement, and validity of an innovative smartphone application with ecological momentary interventions to augment cognitive behavioral therapy for bulimia nervosa.
Physical exercise helps patients with eating disorders by improving their physical fitness, quality of life and other specific variables of this pathology. Pilates has a beneficial effect both physically and mentally on healthy population and other diseases. In patients with eating disorder, Pilates will improve psychic aspects and their physical condition. For all these reasons, the affectation of psychological symptoms will decrease and the quality of life will improve.
Do the current eating disorder treatments, i.e., Family-based Treatment (FBT) and Enhanced Cognitive behavioral therapy (CBT-E), offered at the Center for the Treatment of Eating Disorders (CTED) demonstrate effectiveness? Specifically, which type of treatment is most effective for which diagnoses? Participants with Anorexia Nervosa (AN), Bulimia Nervosa (BN), Other Specified Feeding or Eating Disorder (OSFED), or Unspecified Feeding or Eating Disorder (UFED) in this study will self select one of the two treatment groups, FBT or CBT-E. Additionally, does Family-based Treatment (FBT) modified for Avoidant/Restrictive Food Intake Disorder (ARFID) and Family-based Treatment (FBT) combined with the Unified Protocol (UP) for Transdiagnostic Treatment of Emotional Disorders (FBT+UP for ARFID) demonstrate effectiveness for patients with an Avoidant/Restrictive Food Intake Disorder (ARFID) diagnosis?
Although psychotherapy for eating disorders (EDs) can be effective, approximately 50% of those who complete a course of the best available therapy continue to have significant ED symptoms at the end of treatment. Posttraumatic stress disorder (PTSD) commonly co-occurs with EDs and is thought to be one reason why some individuals do not remit from their ED with best available treatment or relapse following treatment. In particular, ED behaviours can function as coping methods for PTSD symptoms, and thus interfere with successful and lasting ED recovery. The main objective of this initial treatment trial is to determine whether a concurrent treatment approach, in which PTSD symptoms are treated at the same time as ED symptoms, provides an advantage over standard ED treatment by successfully alleviating PTSD symptoms. Forty participants who have both an ED and PTSD will be assigned to receive either (1) standard ED psychotherapy alone or (2) standard ED psychotherapy concurrent with PTSD psychotherapy. After treatment, participants will be followed for a period of 6 months to determine whether improvements made during therapy are maintained after treatment. ED and PTSD symptoms, as well as concomitant symptoms (e.g., anxiety and depression) will be assessed immediately before and after treatment, as well as 3 and 6 months after treatment.
The purpose of this study is to better investigate the efficacy of the PRIDE Body Project in respect to preventing eating disorders in sexual minority men. In this randomized controlled trial, participants will be enrolled in one of two arms: 1) the PRIDE Body Project intervention or 2) Media Advocacy, a time and attention-matched intervention. This study will recruit participants who are between the ages of 18 and 35, identify as men, are gay, bisexual, or experience sexual attraction to men, and who express body image concerns for the San Diego area.
This study uses a computational task to examine differences in adaptive learning to both rewards and punishments between three groups: those who have recovered from anorexia nervosa, those who score highly on the EAT-26 (Eating Attitudes Test - 26 item version; an eating disorder symptom scale), and healthy controls. This task also allows the examination of pupil response (thought to reflect norepinephrine activity) in response to expected and unexpected wins and losses.
This project will evaluate 3 approaches of implementation support for university peer leaders who will deliver a prevention program with a particularly strong evidence-base compared to changes observed in outcomes in response to usual care at the universities before implementation. This study aims to advance knowledge of this innovative and economical way to provide college prevention programs to reduce the burden of mental illness in the college student population.
Interpersonal psychotherapy (IPT) is an evidence-based therapy for the treatment of eating disorders (including binge eating disorder, bulimia nervosa, and disordered eating not meeting full diagnostic criteria). On a basic level, IPT is a time-limited treatment that helps the client understand the relationship between symptoms and social interactions. Traditional training methods require substantial cost, time, and resources, making evidence-based treatments difficult to disseminate. As such, college clinicians are not typically trained in IPT delivery, which prevents their clients from reaping the potential benefits of treatment. This study will attempt to show how technology can overcome such barriers to training dissemination. The purpose of this study is to see if online training in IPT is as effective as in-person training. To find out, the following procedures will occur: First, college mental health clinicians will complete baseline online questionnaires and deliver their usual treatment to 1 or 2 clients with symptoms of eating disorders. Then, they will complete the guided online training program and post-training assessments. Next, they will treat 1 or 2 different clients with eating disorders and complete post-training assessments. As part of the baseline and post-training assessments, clinicians will complete a telephone-based simulation assessment with staff raters, in which the investigators will recreate a client session and rate how well the clinicians adhere to IPT in treating the simulated client. The guided on-line training program will ultimately be compared to the "gold standard" training (the group receiving in-person training in an associated, IRB-approved study, # 201111113).
