This secondary analysis of a pilot randomized controlled trial in people with multiple sclerosis (PwMS) aimed to compare mindfulness-based training (MBT), adaptive cognitive training (aCT), and a waitlist control (WL) on the use of emotion regulation strategies during daily worries and ruminations. Further, we examined cognitive functioning as a moderator of training effects. Research Method/Design: Sixty-one PwMS were randomized into an MBT, aCT, or a WL control group for four weeks. Participants completed daily diaries assessing their use of emotion regulation strategies and measures of cognitive functioning at pre-and posttraining. The frequency of acceptance use, maladaptive strategies, and cognitive reappraisal, as well as the success of acceptance use, were the primary outcomes of interest. We also examined whether a cognitive composite score moderated treatment gains. Results: Relative to pretraining, at posttraining, participants in the MBT group used acceptance more frequently, and this change was significantly greater compared to the change in aCT and WL groups. Training did not have differential effects on the frequency of maladaptive strategy and cognitive reappraisal use or on the success of acceptance use. Cognitive functioning did not moderate observed treatment gains. Conclusion/ Implications: Our findings, based on this pilot study, suggest that after brief training in mindfulness meditation, PwMS used more acceptance strategies to regulate their emotions. Future studies with larger sample sizes, longer duration of treatment, and longitudinal follow-up are needed to better understand the efficacy of mindfulness mediation for promoting affective and cognitive health in PwMS.
Impact and ImplicationsThese secondary analyses of a pilot randomized controlled trial explored the preliminary effects of mindfulness-based training (MBT) on the use of emotion regulation strategies in people with multiple sclerosis (PwMS). Emotion dysregulation has garnered increased support as a transdiagnostic factor underlying psychological disturbances. This study found that a four-week mindfulness program increased the use of acceptance-an adaptive emotion regulation strategy-during daily episodes of worry and rumination compared with an active and a passive control group. Although pretraining differences in acceptance use between the three groups necessitate further research, additional analyses that identified medium effects for the MBT group, provide preliminary evidence that mindfulness training may in fact increase the frequency of acceptance use in PwMS. This study contributes to the literature by exploring the impact of mindfulness training on emotion regulation strategy use in a population with chronic health issues that experiences increased rates of mood and anxiety disorders.
