Using Contextual Behavioral Science to Alleviate Human Suffering

All behavior is wholly sensible in the context in which it emerges.

The ACT in Context Research Lab is a lab affiliated with the ACT at Duke program. It is based in the Duke Division of Behavioral Medicine and led by Dr. Rhonda Merwin. The laboratory uses contextual behavioral science to understand and treat human suffering. Although there are many ways in which humans suffer, current research focuses on suffering that arises from having an adversarial relationship with the body and signals arising from the body (this includes hunger/satiety, but also somatic constitutes of emotion and physical pain). We study populations for whom rejection of body signals has resulted in profound deprivation or impairment, including individuals with anorexia nervosa and individuals with type 1 diabetes who withhold life-saving insulin to lose weight.

Duke T1D Research

Hunger and Hormones Study

Funded by the Duke Department of Psychiatry and Behavioral Science Pilot Research Award

This study investigates appetite regulation among individuals with T1D with eating disorder behaviors. Individuals with and without these behaviors complete an oral glucose tolerance test, during which ghrelin levels, sensations of hunger etc are assessed. 

This study tests a novel intervention for individuals with type 1 diabetes who omit insulin to lose or control weight. Treatment combines mobile technology and individual ACT-based therapy to help individuals recognize triggers for insulin omission in-the-moment and use acceptance, mindfulness and value-oriented skills to cope more effectively.

Real-Time Precursors and Correlates of Maladaptive Eating and Weight Control, R01DK089329

Individuals with type 1 diabetes mellitus (T1D) who develop an eating disorder are at high risk for diabetes-related medical complications and premature death. Eating disorders affect a significant subset of T1D patients who often withhold insulin as a means of controlling weight. Yet what accounts for the prevalence of this dangerous comorbidity and how to effectively treat these patients is unknown. Interventions developed for non-diabetic patients have failed to improve key metabolic parameters in T1D patients, suggesting extant models of eating pathology are inadequate for this unique population. This study tested somatic-affective antecedents to eating disorder symptomatology among individuals with T1D. Participants wore continuous glucose monitors (CGM) while simultaneously being cued to make diary entries of psychological state and behavior (randomly and for all eating episodes). Glucose data and diary data were then time-synced to answer novel questions about eating disorder etiological factors, including whether nonacceptance (or rejection) of diabetes leads to aberrant responding to normal fluctuations in blood glucose.

ACT for Fibromyalgia

This study examined the efficacy of individual Acceptance and Commitment Therapy (ACT) for women with FM, compared to an education-control.  This project was a collaboration with Dr. Bigatti at Indiana University.

ACT for Adolescent Anorexia Nervosa​

Acceptance-based Separated Family Treatment for Adolescent Anorexia Nervosa, (R21 MH085975)

We developed and tested a 20-week acceptance-based separated family treatment (ASFT) for adolescents with anorexia nervosa, or eating disorder NOS in which the primary symptoms were restrictive eating and excessive weight loss. Treatment components were based on ACT and included a parent skills based on Off the C.U.F.F. (Zucker, 2006). This study was in  collaboration with Dr. C. Alix Timko, now at the Children's Hospital of Philadelphia (CHOP).

ACT to Prevent Eating Disorders: Evaluation of the AcceptMe A Digital Gamified Prevention Program Based on Acceptance and Committment Therapy

Doctoral Dissertation, Patrisia Nikolaou

A Dissertation Submitted to the University of Cyprus in Partial Fulfilment of the Requirements for the Degree of Doctor of Philosophy.

The present doctoral thesis aimed to investigate the effectiveness and acceptability of a digital Acceptance and Commitment Therapy (ACT; Hayes et al, 1999) based prevention program in comparison to a wait-list control group for young women identified to be at risk for ED. The goals of the study were to describe the development of the AcceptME protocol and digitalized program, assess participants’ feedback and the acceptability of the program, and examine the effectiveness of the ACT-based prevention program compared to a wait-list control group.
