UJI VALIDITAS DAN REABILITAS THE NEUROLOGICAL DEPRESSION DISORDERS INVENTORY FOR EPILEPSY (NDDI-E) VERSI INDONESIA

Introduction : Depression is a common psychiatric disorder in epilepsy. It is a comorbid condition that adversely decrease patients health-related quality of life, and also potentially lead to the emergence of suicidal habits in people with epilepsy. So it required an instrument that is brief and accurate in Indonesian version, for detection of depression in people with epilepsy. Aims : Determine the validity and reliability the NDDI-E in Indonesian version. Methods : It was a cross-sectional study, which included 30 patients epilepsy in the outpatient clinic Ciptomangunkusumo Hospital Jakarta on June 2013. Transcultral validation based on WHO, and determination ofthe Pearson?s correlation and Crobanch alfa coeffisient for validity and reliability test. Result : There were 30 patients invited to the study, man and woman are equal (50%). From the transcultural validation obtained the NDDI-E in Indonesian version. In validity test with the Pearson?s correlation, it obtained 6-items valid statements. The 1st statement had correlation from the total value 0.898(p<0.01), 2nd statement 0.580(p<0.05), 3rd statement 0.716(p=0.01), 4th statement 0.620(p<0.05), 5th statement 0.681 (p<0.05), and 6th statement 0.888 (p<0.01). Estimation of the reliability with Pearson?s correlation was r=0.935(p<0.001). It showed that the measurements were consistent from time to time (reliable). The reliability of the internal consistency with determination of crobanch alfa coefficient were: 1st statement 0.772>0.6, 2nd statement 0.820>0.6, 3rd statement 0.795>0.6, 4th statement 0.814>0.6, 5th statement 0.803>0.6, and 6th statement 0.741>0.6. Crobanch alfa for all items of the NDDI-E were 0.823>0.6 which means that all items of the NDDI-E statements are consistent and reliable. Discussions : The NDDI-E in Indonesian version was valid and reliable in assessing depression of epilepsy patients.
