Brief Summary

Acceptance and Commitment Therapy (ACT) has been recognized as an effective, non-pharmacologic treatment for a variety of CP conditions. However, little is known about the neurologic mechanisms underlying ACT. The investigators conducted an ACT intervention in women (n=9) with chronic musculoskeletal pain. Functional magnetic resonance imaging (fMRI) data were collected pre- and post-ACT, and changes in functional connectivity (FC) were measured using Network-Based Statistics (NBS). Behavioral outcomes were measured using validated assessments such as the Acceptance \& Action Questionnaire (AAQ-II), the Chronic Pain Acceptance Questionnaire (CPAQ), the Center for Epidemiologic Studies Depression Scale (CES-D), and the NIH Toolbox Neuro-QoLTM (Quality of Life in Neurological Disorders) scales. Results suggest that, following the four-week ACT intervention, participants exhibited reductions in brain activation within and between key networks including self-reflection (default mode, DMN), emotion (salience, SN), and cognitive control (frontal parietal, FPN). These changes in connectivity strength were correlated with changes in behavioral outcomes including decreased depression and pain interference, and increased participation in social roles. This study is one of the first to demonstrate that improved function across the DMN, SN, and FPN may drive the positive outcomes associated with ACT. This study contributes to the emerging evidence supporting the use of neurophysiological indices to characterize treatment effects of alternative and complementary mind-body therapies.

Outcome Measures

Primary Outcomes (1)

  • Change in Network Based Statistic (NBS) from pre-to post-ACT

    Derived from fMRI data, the NBS the Network Based Statistic (NBS) is used to examine changes in functional connectivity from pre-to post ACT.

    Measured by comparison of pre-treatment (baseline) and 4-weeks post-treatment (within 1 week after treatment completion) fMRI scan data

Secondary Outcomes (2)

  • Change in self-reported measures of depression from pre-to post-ACT

    Measured by comparison of pre-treatment (baseline) and 4-week post-treatment (within 1 week after treatment completion) assessment data

  • Change in self-reported measures of satisfaction with social role from pre-to post-ACT

    Measured by comparison of pre-treatment (baseline) and 4-week post-treatment (within 1 week after treatment completion) assessment data

Other Outcomes (3)

  • Change in self-reported measures of pain acceptance from pre-to post-ACT

    Measured by comparison of pre-treatment (baseline) and 4-week post-treatment (within 1 week after treatment completion) assessment data

  • Change in self-reported measures of pain interference from pre-to post-ACT

    Measured by comparison of pre-treatment (baseline) and 4-week post-treatment (within 1 week after treatment completion) assessment data

  • Change in self-reported measures of acceptance and action from pre-to post-ACT

    Measured by comparison of pre-treatment (baseline) and 4-week post-treatment (within 1 week after treatment completion) assessment data

Study Arms (1)

Single Arm (pre-post, quasi-experimental)

OTHER

Pre-post intervention, single arm. (Intervention was 4 weeks of Acceptance and Committment therapy, 2 times per week, 90 min per session, in a group setting).

Behavioral: Acceptance and Committment Therapy

Interventions

Acceptance and Commitment Therapy (ACT) is a mindfulness-based therapy that focuses on enabling individuals to accept what is out of their control, and to commit to valued actions that enrich their lives (Vowles \& McCracken, 2008). By emphasizing acceptance instead of avoidance, ACT differs from many other forms of cognitive behavioral therapy. ACT has been shown to be efficacious in terms of clinical outcomes, adherence to treatment, and retention. ACT aims to increase psychological flexibility, and has been associated with improved health outcomes prior randomized controlled clinical trials, including three systematic reviews specific to CP. Psychological flexibility is defined as an individual's ability to recognize and adapt to various demands; shift mindsets or behavioral responses when these strategies compromise personal or social functioning; and maintain balance among important life domains.
