Prescription opioid misuse among persons with chronic pain is an emerging public health threat of epidemic
proportions. Indeed, misuse of prescription opioids has increased more than threefold over the past 20 years. Though opioid
analgesic therapy for chronic pain is often efficacious, long-term use of opioids may result in heightened sensitivity to pain,
known as hyperalgesia, and risk of developing addiction. These issues emerge from cycle of behavioral escalation where pain and
stress trigger hypervigilance and catastrophizing, biasing attention towards pain and opioid-related cues that fuels dependence
on opioids in spite of ever diminishing analgesia. There is a dearth of therapeutic intervention strategies targeting this stage of
behavioral escalation. As such, we are testing a novel intervention, Mindfulness-Oriented Recovery Enhancement (MORE),
which integrates mindfulness training, cognitive restructuring, and positive emotion regulation to break the cycle of pain and
misuse of opioid medication.
We are conducting a NIH-funded, randomized controlled trial comparing the efficacy of MORE to a conventional
support group (SG) for persons with chronic pain who have been prescribed opioid analgesic therapy for >3 months. Thus far, 33
individuals have been randomly assigned to participate in either 8 weekly, two-hour sessions of MORE (n = 15) or the SG (n =18).
Pre- and post-treatment, participants complete a battery of validated questionnaires, cognitive tasks, and psychophysiological
Thus far, we have identified significant effects of MORE on relief from pain, pain attentional bias, and desire for opioid
medication. We identified a significant Group X Time interaction on relief from pain treatments, F(1,27) = 8.16, p = .01, ηρ
.23, such that participation in MORE was associated with significantly greater increases in relief from pain treatments than the
SG. We identified a significant Group X Time interaction on attentional bias toward pain-related cues, F(1,14) = 4.86, p = .04,
= .26, such that participation in MORE was associated with significantly greater reductions in the pain attentional bias than
the SG. We identified a significant Group X Time interaction on desire for opioid medication, F(1,27) = 4.19, p < .05, ηρ
such that participation in MORE was associated with significantly greater reductions in desire for opioid medication than the
SG. Although there was no significant Group X Time interaction on changes in well-being, there was a significant main effect of
time F(1,28) = 5.67, p = .02, ηρ
= .17, such that participants in both groups reported significant increases in well-being over the
course of the interventions.
