Adapted Motivational Interviewing and Cognitive Behavioural Therapy for Food Addiction
Food AddictionBinge EatingFood addiction is the concept that individuals can be "addicted" to foods, particularly highly processed foods. This concept has attracted growing research interest given rising obesity rates and the engineering of food products. Although food addiction is not a recognized mental disorder, individuals do identify as being addicted to foods and self-help organizations have existed since 1960 to purportedly treat it (i.e., through abstinence). However, little research has been conducted on how abstinence approaches work. Such methods may even be harmful given the risk of disordered eating. Currently, there are no empirically supported treatments for food addiction. However, evidence-based treatments do exist for addictions and eating disorders, such as motivational interviewing and cognitive behavioural therapy, which may prove beneficial for food addiction, given neural similarities between addictions and binge eating. The current study proposes a randomized controlled trial using a four-session adapted motivational interviewing (AMI) and cognitive behavioural therapy (CBT) intervention for food addiction. This intervention combines the personalized assessment feedback and person-centred counseling of AMI with CBT skills for eating disorders, such as self-monitoring of food intake. The aim is to motivate participants to enact behavioural change, such as reduced and moderate consumption of processed foods. Outcome measures will assess food addiction and binge eating symptoms, self-reported consumption of processed foods, readiness for change, eating self-efficacy, and other constructs such as emotional eating. The intervention condition will be compared to a waitlist control group. Both groups will be assessed at pre- and postintervention periods, as well as over a 3-month follow-up period to assess maintenance effects. Based on a power analysis and previous effect sizes following AMI interventions for binge eating, a total sample size of n = 58 is needed. A total of 131 individuals will be recruited to account for previous exclusion and withdrawal rates. Participation is estimated to take place from March 2021 to March 2022. All intervention sessions will be conducted virtually over secure videoconferencing technology or telephone, expanding access to all adult community members across Ontario, Canada. Twenty randomly selected session tapes will be reviewed for MI adherence.
Behavioral Weight Loss Treatment for Individuals With Food Addiction
Food AddictionOverweight and Obesity1 moreThe purpose of this research study is to examine how well an existing weight loss treatment works for individuals with food addiction. Treatment will consist of a preliminary 12-week RCT pilot of the feasibility and effectiveness of behavioral weight loss (BWL) compared to a waitlist control.
Assessment of and Treatment Applied to Food Addiction in a Rural Healthy Behaviors Clinic
ObesityResearch purpose: The purpose of this pilot study is to assess obese clients for two phenotypes, those testing positive and those testing negative for Food Addiction (FA) (Yale Food Addiction Scale, YFAS) and determining the efficacy of four treatments: usual care (IC, dietary and physical activity instruction), individual motivational interviewing alone (MI), individual MI with pharmacotherapy (MI+P) for improving outcome measures within each phenotype, and pharmacological therapy (P). Background/significance: Obesity has long been an epidemic in the U.S. and other countries. Numerous approaches have been tried to address obesity with limited success. The YFAS is a relatively new, validated instrument that can help researchers and practitioners assess obese clients for food addiction. Meeting the YFAS diagnosis criteria for FA suggests the need for a stronger intervention with close monitoring to assist these clients in self-management of their eating and physical activity behaviors. Proposed methods/approach: The investigators propose assessing obese clients with the YFAS as part of their intake once they are referred to the Healthy Behaviors Clinic by Regional West physicians/practitioners. A nurse researcher with expertise in MI and a nurse practitioner will perform intake assessments, obtain consent and randomly assign participants in each phenotype (positive or negative for FA) to one of three treatment groups (usual care, individual MI alone, and individual MI with pharmacotherapy). Interventions will occur over 6 months. A clinical psychologist with expertise in the YFAS (University of Michigan) will serve as a consultant on this project and a registered dietitian (University of NebraskaLincoln) will serve as a co-investigator. Expected outcomes: The investigators expect that MI and MI+P and P will be more effective in improving outcome measures than IC. We also expect that response to the treatments will differ between the two obesity phenotypes (those testing positive and those testing negative for FA).
Food Addiction and Motivational Interviewing in Nursing Students
Food AddictionThe aim of this study is to determine the effect of online group motivational interviewing (MI) on eating behavior, healthy lifestyle behaviors and quality of life in nursing participants with food addiction at three state universities in Ankara. The population of the research will be those who meet the diagnostic criteria for food addiction according to the Yale Food Addiction Scale. The research sample size was calculated with the G* Power package program. As a result of the power analysis, a total of 52 participants, 26 for the intervention group and 26 for the control group, were found sufficient for the sample with 90% power, 5% margin of error and 0.2065 effect size. Considering that the number of participants would decrease during the research process, the number of samples was increased by 10% to a total of 58 university participants, 29 of which were interventions and 29 were controls. Among the participants who meet the food addiction criteria, the participants who meet the inclusion criteria and agree to participate in the research will be randomly assigned to the intervention and control groups (n1=29; n2=29). After these participants are stratified according to the change (pre-contemplation and contemplation stage) phase, a simple random assignment process within the strata will be done by an independent researcher to avoid selection bias. Random assignment will be done through a simple random numbers table. The independent researcher who does not know which group is the intervention group and which group is the control group will collect the data. Data collection tools will be applied to the participants in the intervention and control groups in the pre-MI session, the post-MI session, and 2 months later in the follow-up session. It was planned to apply 5 sessions of MI to the intervention group, and to follow-up 2 months after the interviews were completed. No application will be made to the participants in the control group, and at the end of the study, a seminar on food addiction and quality of life will be given to the participants.

Effect of Transcranial Direct-current Stimulation in Eating Behavior of Women With Fibromyalgia...
FibromyalgiaFood AddictionIntroduction: Fibromyalgia (FM) is a syndrome characterized by generalized musculoskeletal pain, fatigue, non-repairing sleep, cognitive changes, depressive symptoms and other correlates of autonomic dysfunction. A high prevalence of overweight in patients with fibromyalgia is observed, about 80% according to current data, which affects the course and prognosis of the disease, besides overburdening health costs and further compromising quality of life. life of these patients. Evidence shows possible pathophysiological pathways shared by these two pathologies, as well as aspects related to food behavior. It is known that dopaminergic neurotransmission is altered in both, suggesting an increase in the sensitivity or density of D2 dopamine receptors. Non-pharmacological options for pain management and dysfunctional eating behavior include the important contribution of neuromodulatory techniques of non-invasive cerebral stimulation, such as transcranial direct current stimulation (tDCS), which aims to increase resisting hyperpalatable foods and reducing caloric intake. Objectives: To evaluate the association between dopamine receptor-2 (DRD2) Taq1A allele A1 polymorphism (rs1800497) and to observe the possible effect of tDCS on the dorsolateral prefrontal cortex (DLPFC) on homeostatic and hedonistic aspects of eating behavior in women with FM. Methods: A randomized, double blind, parallel group, controlled trial with simulated treatment will be performed. Will be included in the study women literate, right-handed, with confirmed diagnosis of FM. The evaluation will be done through questionnaires on pain and eating behavior, anthropometric evaluation and biochemical measurements. The intervention will take place through active or simulated home for 4 weeks. Perspectives: To evaluate dysfunctional neuroplastic changes in eating behavior and biological markers and also to serve as a basis for future effective treatment strategies through neuromodulation and nutritional counseling.
The Effect of Brain Stimulation (tDCS) in Food Cravings Control in Overweight/Obese Women
ObesityThis study is a randomized clinical trial to test the effect of a type of non-invasive brain stimulation on the response to a behavioral intervention designed to enhance cognitive control over food cravings in obese and overweight women. The brain stimulation is called transcranial Direct Current Stimulation (tDCS). All eligible participants will engage in a behavioral intervention known to enhance control over food cravings and will be randomly assigned to receive either tDCS or sham stimulation to the prefrontal cortex of the brain.
Deep Transcranial Magnetic Stimulation (TMS) With Paired Associative Stimulation (PAS) for the Treatment...
ObesityThe neurobiological underpinnings of obesity point to brain asymmetry in cortical and deeper brain regions. Furthermore, chemical, structural and functional imbalance in cortical and sub-cortical brain regions alters reward processing, attentional control and self-regulation in food-addicted obese individuals. In this study the investigators use TMS with a special multichannel H-coil developed by their lab to safely stimulate cortical and deeper brain regions in obese humans. The investigators aim to produce interhemispheric neuroplasticity (INP) using a paired associative stimulation (PAS) protocol over the DLPFC, to restore neurobiological functioning, alleviate food addiction symptoms, and promote weight loss.

The Biobehavioral Impact of Diet Quality on Affect and Craving
Food AddictionWithdrawalThe current study experimentally investigates whether reducing highly processed (HP) foods (defined in this study as foods high in added sugars) leads to, psychological and / or behavioral indicators of withdrawal. The following hypotheses are tested: To test the hypothesis that reducing highly processed food intake will result in higher daily reports of physical (e.g. headaches), cognitive (e.g. difficulty concentrating), and affective (e.g., irritability) withdrawal symptoms). To test the hypothesis that reducing highly processed food intake will result in increased negative affect (e.g., irritability, depression) as indicated by and psychological (self - reported distress ratings; daily emotion / mood reports) measures. To test the hypothesis that reducing highly processed food intake will result in increased food craving as indicated by psychological (self - report craving ratings; daily craving report) measures. All activities are completed remotely. Participants complete 4 phone appointments with a trained member of the research team. Daily questionnaires and ecological momentary assessments are completed at home between phone appointments. The initial call signs electronic consent and gets baseline measurements (questionnaires). After the initial call, participants start an active assessment period (pre / post dietary change assessments). Pre-dietary change includes at home questionnaires and ecological momentary assessments while eating a typical diet. It also includes the second phone appointment. Post-dietary change includes at home questionnaires and ecological momentary assessments while consuming 3 days of food portions lower in highly processed foods. Participants will complete a food journal on the remaining 2 days of post - dietary change assessment to report what food they ate. Post - dietary change also includes the third phone appointment. The second and third phone appointments each include computer tasks and questionnaires. The final phone appointment is a debriefing interview. Participants planning to continue eating a healthier diet may also be invited to complete a follow-up period, which involves answering a short questionnaire at home every other day for two weeks. 7 individuals had in-person data collected prior to the pandemic requiring a shift to virtual data collection.
