Description
This study examined whether cognitive behavioral therapy and mindfulness interventions affect positive (PA) and negative affect (NA) reports for patients with rheumatoid arthritis (RA) before, during, and after stress induction. The study also investigated the effects of a history of recurrent depression on intervention effects and testing effects due to the Solomon-6 study design utilized. The 144 RA patients were assessed for a history of major depressive episodes by diagnostic interview and half of the participants completed a laboratory study before the intervention began. The RA patients were randomly assigned to 1 of 3 treatments: cognitive behavioral therapy for pain (P), mindfulness meditation and emotion regulation therapy (M), or education only attention control group (E). Upon completion of the intervention, 128 of the RA patients participated in a laboratory session designed to induce stress in which they were asked to report on their PA and NA throughout the laboratory study. Patients in the M group exhibited dampened negative and positive affective reactivity to stress, and sustained PA at recovery, compared to the P and E groups. PA increased in response to induced stress for all groups, suggesting an "emotional immune response." History of recurrent depression increased negative affective reactivity, but did not predict reports of PA. RA patients who underwent a pre-intervention laboratory study showed less reactivity to stressors for both NA and PA during the post-intervention laboratory study. The M intervention demonstrated dampened emotional reactions to stress and lessened loss of PA after stress induction, displaying active emotion regulation in comparison to the other groups. These findings provide additional information about the effects of mindfulness on the dynamics of affect and adaptation to stress in chronic pain patients.
