Epilepsy Surgery Satisfaction Questionnaire (ESSQ-19) 

There is a need for valid instruments to assess satisfaction with surgical interventions in epilepsy patients. Using psychometric methodology and data collected in multiple tertiary epilepsy centers, we derived and validated a 19-item self-administered questionnaire, the ESSQ-19 which consists of  four domains: seizure control, psychosocial functioning, surgical complications, recovery from surgery, and one global satisfaction item. The new, valid and reliable ESSQ-19 can be used in clinical and research settings. Further evaluation of the ESSQ-19 is required across different languages, and to measure clinical change over time. The development of this measure was led by Dr Samuel Wiebe (President, ILEA).sRMDA provided statistical support and led the psychometric evaluation of the ESSQ.

Global Assessment of Migraine Severity (GAMS)

Migraine severity is an important clinical endpoint in several clinical and epidemiological studies then assessing treatment efficacy in the management of migraine. The limitations of longer severity measures are addressed in a brief single item patient-reported measure, the Global Assessment of Migraine Severity (GAMS), developed to assess patients’ perception of their disease severity.
