Significance: The purpose of this exploratory study is to test the feasibility, accessibility, and effects of a mindfulness-based stress reduction program (MBSR) on reducing pain catastrophizing in persons with sickle cell disease (SCD) and chronic pain. One of the most difficult symptoms for SCD patients to manage is chronic pain. Approximately one-third of SCD patients experience chronic pain, which is associated with pain catastrophizing. Pain catastrophizing is a negative mental state toward pain stimuli and pain experience, and is associated with increased pain severity, pain interference, and lower social functioning, physical functioning, and mental health. There have been no psychobehavioral intervention studies that have attempted to alter the experience of pain catastrophizing in persons with SCD. MBSR is a complementary group-based therapy that emphasizes nonjudgmental awareness of thoughts, feelings, and bodily sensations. With no pharmacological or non-pharmacological treatment for catastrophizing in persons with SCD, MBSR offers a potential solution to this highly significant problem for both SCD patients and providers. This project will be the first randomized controlled trial (RCT) of MBSR to reduce pain catastrophizing, and improve quality of life for SCD patients with chronic pain.

Methods: This study will enroll 60 adult patients with SCD and chronic pain from the Duke Adult Sickle Cell Clinic. Patients will be randomized to a MBSR or wait-listed control group. The MBSR group will complete a 6- week, group-based telephonic MBSR program that is administered by a certified MBSR clinician once a week for 90 minutes. MBSR feasibility, acceptability, and effects on pain catastrophizing will be assessed by questionnaires at baseline, week 1, 3, and 6 in both groups. At the end of week 6, 10 randomly selected MBSR participants will complete semi-scripted telephone interviews to help assess intervention acceptability, and the wait-listed control condition will be offered the same MBSR intervention.

Study Design

Allocation randomized
Intervention model single group assignment
Masking open label
Primary purpose supportive care
Subjects assigned to the experimental group will participate in a MBSR foundation program, which includes weekly telephonic, group-based, 60-minute MBSR sessions for 6 weeks. The foundation program will introduce subjects to the concept of mindfulness with each week focusing on a different facet. Modeled after Kabat-Zinn's original program, breath awareness (focus on breath and observing thoughts without fighting or following them), body scan (promoting mindfulness of sensations in different parts of body), walking meditation (walking as form of meditation), loving kindness (projection of friendliness and kindness towards oneself and others), and choiceness awareness (awareness of all sensations with equal interest) will be taught.
mindfulness-based stress reduction
A non-pharmacological approach to pain management.
Subjects assigned to the wait-listed control group will not receive the MBSR program, but will receive weekly reminders of their study participation, be asked to complete the same questionnaires (per telephone script) once every three weeks, and receive the same financial incentives as the MBSR group. Upon completion of the 6-week session, the wait-list control group will be offered the same MBSR program. At that time, a new series of MBSR sessions will be scheduled and offered to the wait-listed control patients. Subjects who elect to participate in MBSR will receive the same packet of materials and measures received by the intervention group and be asked to complete the measures again at baseline, 1, 3, and 6 weeks.
