A Promising Distance-Delivered Intervention for Depression Among People with Epilepsy


Emory University: Prevention Research Center
 



Using Practice and Learning to Increase Favorable Thoughts

Telephone- or Internet-delivered cognitive-behavioral therapy plus mindfulness training for people with epilepsy and depression

Intervention of eight, weekly 1-hour sessions

Depression scores decreased significantly in participants compared to controls

Potential utility for expanding to homebound populations with depression


Background

Depression is often underdiagnosed and undertreated among people with epilepsy, a brain disorder characterized by repeated and unpredictable seizures. People with epilepsy have many risk factors for depression, including restriction of driving (and therefore limited employability), stigmatization, isolation, dependency on others, and concerns about adding medications to the epilepsy regimen. Research suggests that depression is both biological and cognitive; thus, interventions may include medications for the biologic component and therapy to change patterns of thought.

Context

Project UPLIFT combines cognitive-behavioral therapy and mindfulness training to help people with epilepsy and depression manage their symptoms of and reduce depression. The intervention consists of eight, 1-hour sessions for groups of six to eight people with epilepsy and depression. Sessions include discussions, instruction, and skill-building exercises, as well as didactic presentations about epilepsy. Participants practice relaxation exercises and skills, including monitoring their thoughts, identifying their cognitive distortions, identifying problems and supports available to address them, and setting goals. Mindfulness topics covered include meditation, the impermanent nature of thoughts, and awareness of pleasure. The goal is for participants to identify and modify their thoughts (cognitive-behavioral components) and to become aware of and nonreactive to negative thoughts (mindfulness). Prior to program implementation, a formative evaluation was conducted among nine people with epilepsy and depression who were recruited from a hospital-based epilepsy clinic. On the basis of their responses, gained through focus group research (fall 2007), the program appeared acceptable to people with epilepsy and depression.1

Methods & Results

The program is delivered over the telephone or the Internet; both modes are facilitated by a person with epilepsy and a Master of Public Health student, supervised by a licensed clinical psychologist. Telephone participants attend one conference call per week; Internet attendees log onto a secure web site to view one session per week and may log on multiple times to follow and participate in discussion boards. People who miss a telephone or Internet session are called by a research assistant who asks about their mood and well-being, and reminds them of the next session. If the research assistant perceives any acute distress, the clinical psychologist is notified.

Adults with epilepsy were recruited from a hospital-based epilepsy clinic and screened for depression using the Center for Epidemiologic Studies Depression Scale. Baseline, interim (8 weeks), and follow-up measures (16 weeks) were made for 53 participants who, after stratification by depression medication use (so that all groups would include some people who were taking depression medication), were randomized to the telephone or Internet program delivery mode. Participants in each delivery mode were further randomized to immediate treatment (intervention starting after the baseline measure) or wait list (intervention starting at week 8, after the interim measures were taken). Thus, four study strata were established, and the wait list groups served as controls for the immediate treatment groups. Outcome measures, collected by telephone by a research assistant, included depressive symptoms (measured by the Beck Depression Inventory [BDI]), knowledge (measured by 18 true-false questions), skills (measured by Likert scale responses to questions about perceived ability to use skills), self-efficacy (measured by the Depression Coping Self-Efficacy Scale), satisfaction with life (measured by the Satisfaction With Life Scale), and quality of life (measured by questions from the Behavioral Risk Factor Survey).

The median number of sessions attended was six. The main outcome measured—change in depressive symptoms—differed little by delivery mode: as measured by the BDI, mean depression scores decreased 10.2 (68%) for the telephone group, 9.2 (59%) for the Internet group, and only 1.8 (15%) for the wait list group. The intervention groups showed a greater increase in knowledge and skills than the wait list group, and this change was associated with improvement in depression. Differences in self-efficacy, satisfaction with life, and quality of life measures were not statistically significant; however, changes for these measures favored the intervention groups.2

Formative data suggested the program components were well received and beneficial; however, telephone participants expressed greater overall satisfaction with the program than the Internet participants did. Participants in both groups found that the group nature of the program, which facilitates communication among people with epilepsy, was an important component of the program.

Consequences

Based on the results of the pilot study, distance delivery of this depression intervention appears promising for people with epilepsy and depression. Now a slightly modified intervention is being tested in four states (Georgia, Michigan, Texas, and Washington) for depression prevention rather than treatment among people with epilepsy. Initial results appear promising. Because people can participate in the intervention from their home (or any location convenient to them), the telephone or Internet intervention may have potential for reducing depression in a wide range of populations who are homebound.
