Telephone-Based Support Programs for People With Epilepsy

The primary outcome is a dichotomous measure of depressive symptoms based on a Patient Health Questionnaire (PHQ-9) score of <5 versus ≥5. The PHQ-9 assesses depressive symptoms in the past two weeks. Total scores range from 0-27 with recommended cutoffs for mild (5-9), moderate (10-14), moderately severe (15-19) and severe (≥20) depressive symptoms. A PHQ-9 score of <5 indicates absence of clinically significant depressive symptoms.

Continuous PHQ-9 scores will be used to evaluate the magnitude of change in depressive symptoms. The PHQ-9 consists of nine questions that ask respondents how often they've "been bothered by any of the following problems" in the past two weeks. The questions address sleep, energy, appetite, and other possible symptoms of depression. Scores are calculated based on how frequently a person experiences these feelings. Score of 1-4 is considered minimal depression; score of 5-9 is considered mild depression; score of 10-14 is considered moderate depression; score of 15-19 is considered moderately severe depression; score of 20-27 is considered severe depression.

This will be assessed by self-reported 30-day seizure counts.

This will be assessed by a 12-item version of the Liverpool Seizure Severity Scale. The possible scoring ranges are between 7 and 32 for the percept scale and between 10 and 48 for the ictal/postictal scale. The higher the score the more severe the seizures.

This will be assessed by the Quality of Life in Epilepsy-10 (QOLIE-10) questionnaire, a 10-item measure of epilepsy-specific aspects of qualify of life. The QOLIE-10-P is a brief survey of health-related quality of life for adults with epilepsy. There are 10 questions about health and daily activities, one question about how much distress you feel about problems and worries related to epilepsy, and a review of what bothers you most.

This will be assessed by the Patient-Reported Outcomes Measurement Information System (PROMIS-10) questionnaire, a 10-item measure of global health (physical, mental and social functioning) developed by NIH as an indicator for Healthy People 2020. The PROMIS Global-10 is a 10-item patient-reported questionnaire in which the response options are presented as 5-point (as well as a single 11-point) rating scales. The results of the questions are used to calculate two summary scores: a Global Physical Health Score and a Global Mental Health score. These scores are then standardized to the general population, using the "T-Score". The average "T-Score" for the United States population is 50 points, with a standard deviation of 10 points. Higher scores indicate a healthier patient.
