Use of Mindfulness-based Cognitive Therapy to Change Pain-related Cognitive Processing in Patients with Primary Headache: A Randomized Trial with Attention Placebo Control Group
Mindfulness-based interventionshaveshowntobeefficient inmanagingchronic pain. Cognitive factors play a prominent role in chronic pain complications and negative cognitive contents about pain are often the first issues targeted in cognitivebased therapies, which are known as first-line treatment of chronic pain over the past decades. Little, however, is known about the manner of thinking about pain or pain-related cognitive processing.
Therefore, the purpose of this study was to investigate the effect of mindfulness-based cognitive therapy (MBCT) on pain-related cognitive processing and control of chronic pain in patients with primary headache.
A clinical trial was conducted in 2017 - 2018 on 85 Persian language patients with one type of primary headache selected through purposive sampling inEmamHossein Hospital in Tehran province. To measure the variables of the study, we used the Brief Pain Inventory (BPI) and Pain-related Cognitive Processing Questionnaire (PCPQ). All data were analyzed by independent t-test and chi-square and longitudinal data were analyzed using linear mixed model analysis.
Statistically significant timegroup interactions were found in pain intensity (P < 0.001), pain interference (P < 0.001), as well as in three cognitive processing subscales including pain focus, pain distancing, and pain openness (P < 0.001). However, the results of pain diversion were not meaningful.
MBCTis a potentially efficacious approach for individuals with headache pain. Regulation and correction of cognitive processing are considered as effective cognitive coping strategies in MBCT treatment.
