This is a multicenter study consisting of a Screen and Retest phase conducted in two separate days separated by a two-week period. After providing written informed consent and meeting protocol-defined inclusion criteria at Screen, patients will be administered the Wide Range Achievement Test 3 (WRAT3) to ensure adequate word reading ability with which to complete the self-report forms. Patients who achieve a satisfactory score will be interviewed using the Mini International Neuropsychiatric Interview (MINI). Afterwards, each patient will first complete the 46 item Mood and Anxiety Symptom List in Epilepsy (MAS-E) and then five additional questionnaires in random order. Patients will also be given the opportunity to be rated by a proxy (e.g., caregiver, family member, friend) who will also complete the MAS-E.
