Summary
Objective
Depression and anxiety are highly prevalent among people with epilepsy (PwE) but often remain unrecognized and treated inadequately. Effective psychosocial treatments such as cognitive behavioral therapy (CBT) are rarely available to most PwE, which is one reason electronically delivered CBT (eCBT) is regarded as promising. This study examined an eCBT intervention, termed Emyna, that was tailored to suit the needs of PwE. It includes CBTârelated content on depression, stress and anxiety, seizure triggers and auras, and lifestyle habits. The trial examined the efficacy of Emyna in reducing symptoms of depression (primary outcome) and anxiety as well as improving quality of life.
Methods
Participants (NÂ =Â 200) with epilepsy, a diagnosis of a depressive disorder, and at least moderate depressive symptoms were randomized to Emyna or care as usual. At baseline and after 3, 6, and 9Â months, participants were invited to complete online questionnaires. The primary outcome was improvement of depressive symptoms at 3Â months.
Results
Relative to the control group, intervention group participants experienced significantly greater improvements in depression, anxiety, stress, socialâoccupational impairment, and epilepsyârelated quality of life, in both intentionâtoâtreat (ITT) and perâprotocol analyses. In ITT analyses, effects of medium magnitude were observed, as measured by the Patient Health Questionnaireâ9 items (Cohen d = 0.54, 95% confidence interval [CI] = 0.25â0.82, P < 0.001) and the Neurological Disorders Depression Inventory for Epilepsy (d = 0.51, 95% CI = 0.23â0.79, P < 0.01). At 3 months, intervention group participants also reported fewer illnessârelated days off work and fewer days hospitalized over the preceding months, compared to control group participants (P â€Â 0.05), whereas no such differences were present at baseline (P > 0.30).
Significance
These findings showed that Emyna, used adjunctively to usual care, could help improve mental health, socialâoccupational functioning, and quality of life among PwE. The program provides an additional treatment option that could produce clinically relevant symptom reductions and reduce key cost drivers (ie, hospitalization rates and illnessârelated inability to work).
