Objective
Depression affects about 16% of the U.S. population over a lifetime. People with chronic diseases have especially high rates of co-morbid depression; 32% to 48% of people with epilepsy experience depression. This study evaluated the efficacy of a mindfulness-based cognitive therapy (MBCT) intervention for preventing major depressive disorder (MDD) episodes in people with epilepsy.
Method
Participants (n = 128) were adults from Georgia, Michigan, Texas, and Washington with epilepsy and mild/moderate depressive symptoms. The eight-session, weekly Project UPLIFT intervention, based on MBCT, was group-delivered via Web or telephone. Using a randomized, controlled, cross-over design, participants were assigned to Project UPLIFT or a treatment-as-usual (TAU) waitlist and assessed at baseline, and after intervening in the intervention group (~10 weeks) and in the TAU group (~20 weeks). Assessments included valid self-report measures of depression and MDD, knowledge/skills, and satisfaction with life.
Results
The incidence of MDD episodes (new or relapse) from baseline to interim assessment was significantly lower in the intervention condition (0.0%) than in TAU (10.7%). Depressive symptoms decreased significantly more in the intervention condition than in TAU; Web- and telephone did not differ. Change in knowledge/skills mediated the effect, which persisted over the 10 weeks of follow-up. Knowledge/skills and life satisfaction increased significantly more in the intervention condition than in TAU.
Conclusions
Distance delivery of group MBCT can prevent episodes of MDD, reduce symptoms of depression, and increase life satisfaction in people with epilepsy. This intervention is easily modified for persons with other chronic diseases and other disparity populations.
Community coalitions can successfully achieve asthma policy and system changes and improve health outcomes. Increased core and ongoing community stakeholder participation rather than a higher overall number of participants was associated with more change.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
