All subjects will be contacted by phone at 3 month follow-up. If necessary they will be called 5 times at various times during the day and early evening. If they are not reached, they will receive a letter requesting them to contact the study staff to complete the study. Subjects will be questioned about their adherence to treatment. The primary outcome will be the number of psychotherapy sessions for the treatment of PNES in which they have participated over the past three months. They will also be assessed for secondary outcomes including dichotomous adherence (either seizure freedom or active participation in psychotherapy for the treatment of PNES, with more than 5 sessions over the past 3 months), seizure frequency over the past month, number of hospitalizations and emergency department visits over the past 3 months, and quality of life as measured by the brief QOLIE-10 instrument. For those patients who give permission, their psychotherapists will be contacted by study staff to confirm the exact number of psychotherapy sessions over the past 3 months. A standard Partners clinical records release form with the patient's signature will be sent to the therapist's office.
