About this study

Official title: Using fMRI to Understand Response to an Integrative Treatment for Pain and Anxiety in Pediatric Functional Abdominal Pain Disorders (FAPD)

Complex functional abdominal pain disorders (FAPD) with co-occurring anxiety are highly prevalent in children, can be very disabling, and are not responsive to currently available treatments. This research aims to better understand the neural mechanisms involved in a promising nonpharmacological treatment for FAPD to ultimately guide the development of more targeted treatment approaches for afflicted youth.

Read the detailed description

Functional abdominal pain disorders (FAPD) are among the most common chronic pain conditions of childhood and are associated with significant functional disability, pain, and comorbid anxiety that adversely impacts treatment outcomes. Thus, the PI developed a psychological intervention, Aim to Decrease Anxiety and Pain Treatment (ADAPT; F32HD078049), that targets both pain and anxiety using cognitive behavioral therapy and mindfulness meditation approaches to improve patient outcomes. Preliminary testing has shown that ADAPT reduces pain and anxiety in youth with FAPD. In this study, brain mechanisms implicated in the modulation of pain and response to ADAPT will be investigated. Participants with FAPD and comorbid anxiety will be randomized to either ADAPT or a waitlist control (each condition will last for approximately 6 weeks). Participants will undergo fMRIs to explore changes in functional connectivity and regional brain activation during visceral pain induction (via the water load symptom provocation task; WL-SPT). In Aim 1, functional connectivity patterns associated with a subjective response to pain induction in youth with FAPD who receive ADAPT will be compared to the waitlist control. Conventional blood oxygenation level dependent (BOLD) fMRI will be used to assess functional connectivity to capture moment-to-moment fluctuations in activity. In Aim 2, changes in regional brain activation for those receiving ADAPT will be compared to those in the waitlist condition. The novel arterial spin label (ASL) MRI technique will be used to gain inferences into regional brain activity. In line with the NCCIH funding priorities, this study seeks to increase understanding of the mechanisms through which mind and body approaches impact clinical outcomes in chronic pain and anxiety. Results will advance the field by providing crucial information needed for the refinement and testing of a tailored mind body intervention for FAPD and comorbid anxiety.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ADAPTBehavioural

    Aim to Decrease Anxiety and Pain Treatment is a remotely delivered tailored treatment integrating mindfulness meditation and cognitive behavioral therapy. It consists of 6 sessions and blends pain and anxiety coping strategies. The first 2 sessions will be interactive with a trained psychological provider and the following 4 sessions will be web-based. Each web-based session will be followed by therapist support. The intervention is delivered through a HIPAA compliant video platform.
