title: Sensitivity testing of the Seizure Severity Questionnaire (SSQ).
abstract: The sensitivity of the Seizure Severity Questionnaire (SSQ) was evaluated using pooled data from open-label extensions of two clinical trials in patients with partial-onset seizures. The SSQ includes questions relating to frequency and helpfulness of warning signs as well as frequency, severity, and bothersomeness of ictal and postictal effects. Differences between mean change from baseline for each SSQ item for responders and nonresponders were described and compared between patients solely with complex partial seizures (CPSs: responders, n=166; nonresponders, n=127) and those solely with secondarily generalized partial seizures (SGPSs: responders, n=26; nonresponders, n=24) at baseline. Seizure Severity Questionnaire total score and individual SSQ items related to ictal movement, consciousness, bothersomeness of postictal effects, and frequency of postictal emotional effects showed differentiation between seizure type responders. These data provide further validation of the SSQ by demonstrating its sensitivity in describing treatment effects.
