Objective: To develop a short version of the Srithanya screening tests for epilepsy.
Methods: A prospective study was carried out from September to December 2011. The 10 item- version of the Srithanya screening test was applied to 206 subjects. Item reduction by 7 statistical methods were used. Optimal cut off point by receiving operating characteristic curve (ROC) was calculated to compare areas under curve (AUC) of short form and other versions.
Results: There were 55 epileptic patients and 151 control cases who completed the questionnaire. The short version of 5 items (1, 2, 6, 8 and 10) were selected with these methods and expertsâ€™ opinions. There were 1) loss of consciousness, during attack, 2) canâ€™t remember an event, 3) tongue bite, 4) confused after the attack and 5) told by other person about having epilepsy. The internal consistency was highly acceptable. The optimal cut off-score at 2 had sensitivity and specificity at 92.7 and 90.7% respectively.
Conclusion: The short version of the Srithanya screening test for epilepsy consisted of 5 items could detect people with both types of generalized seizure and complex partial seizure in a hospital setting.
