A new Seizure Severity Questionnaire (SSQ) was developed to assess treatment response. The SSQ demonstrates good reliability and validity, effectively capturing seizure components for clinical evaluation.

Area of Science:

  • Neurology
  • Psychometrics
  • Clinical Assessment

Background:

  • Assessing seizure severity is crucial for evaluating treatment efficacy in epilepsy.
  • Existing measures may not comprehensively capture the multifaceted nature of seizure experiences.
  • A validated tool is needed to objectively measure treatment response.

Purpose of the Study:

  • To develop and validate a new scale, the Seizure Severity Questionnaire (SSQ), for assessing seizure severity.
  • To establish the psychometric properties of the SSQ as a measure of treatment response.

Main Methods:

  • Item generation involved literature review and input from patients and epileptologists.
  • Face and content validity were assessed through pilot studies with patients and observers.

  • Reliability (inter-rater, test-retest) and construct validity were evaluated using established psychometric methods.

    • Main Results:

    • The Seizure Severity Questionnaire (SSQ) was structured into warning, activity-movement, and recovery stages.
    • The SSQ demonstrated good inter-rater reliability (0.76) and test-retest reliability (0.74).
    • Construct validity was supported by significant correlations with existing scales, indicating it measures seizure severity effectively.

    Conclusions:

    • The Seizure Severity Questionnaire (SSQ) possesses favorable psychometric properties, including validity and reliability.
    • The SSQ Summary Score reliably represents key seizure components, making it a valuable tool for clinical use.
    • This study provides initial evidence for the SSQ's utility in assessing seizure severity and treatment response.
