Inter-participant agreement in the selection of symptoms for the description of seizures.

Purpose: To evaluate the inter-participant agreement in the selection of symptoms for the description of seizure types.
Methods: We evaluated the inter-participant agreement for a number of seizure types by comparing the actual agreement to the agreement that would result from random symptom selection as well as the maximal attainable agreement among participants that selected a different number of symptoms.
Results: For all seizure types the agreement in the symptom selection among the majority of the participants is significantly higher than expected by chance, but not reaching the maximum agreement attainable.
Conclusion: Although the maximum agreement possible is not obtained, the symptoms selected by a majority of the participants seem to be adequate for the description of seizure types.
