Abstract

Objective To evaluate the effects of a mindfulness-based group intervention, the Vitality Training Programme (VTP), in adults with inflammatory rheumatic joint diseases.

Methods In a randomised controlled trial, the VTP—a 10-session mindfulness-based group intervention including a booster session after 6 months—was compared with a control group that received routine care plus a CD for voluntary use with mindfulness-based home exercises. The primary outcome was psychological distress measured by the General Health Questionnaire-20. Self-efficacy (pain and symptoms) and emotion-focused coping (emotional processing and expression) were used as co-primary outcomes. Secondary outcomes included pain, fatigue, patient global disease activity, self-care ability and well-being. Effects were estimated by mixed models repeated measures post-intervention and at 12-month follow-up.

Results Of 73 participants randomised, 68 completed assessments post-intervention and 67 at 12 months. Significant treatment effects in favour of the VTP group were found post-treatment and maintained at 12 months in psychological distress (adjusted mean between-group difference −3.7, 95% CI −6.3 to −1.1), self-efficacy pain (9.1, 95% CI 3.4 to 14.8) and symptoms (13.1, 95% CI 6.7 to 19.3), emotional processing (0.3, 95% CI 0.02 to 0.5), fatigue (−1.1, 95% CI −1.8 to −0.4), self-care ability (1.0, 95% CI 0.5 to 1.6) and overall well-being (0.6, 95% CI 0.1 to 1.2). No significant group differences were found in emotional expression, pain or disease activity.

Conclusion The VTP improved most primary and secondary outcomes compared with individual use of CD exercises. Improvements were maintained at 12 months, suggesting that the VTP is a beneficial complement to existing treatments for patients with inflammatory rheumatic joint diseases.
