ABSTRAK Latar Belakang. Gangguan cemas menyeluruh (GCM) merupakan salah satu bentuk gangguan ansietas tersering pada populasi epilepsi yang dapat menurunkan kualitas hidup, sehingga deteksi dini sangatlah penting. Generalized Anxiety Disorder-7 (GAD-7) merupakan instrumen penapis GCM satu-satunya yang pernah divalidasi pada pasien epilepsi, yaitu di Korea dengan titik potong ≥7. Instrumen GAD-7 dapat dikerjakan pasien sendiri kurang dari 3 menit, sehingga cocok digunakan di poliklinik neurologi. Penelitian ini bertujuan untuk mendapatkan kuesioner GAD-7 versi bahasa Indonesia yang valid, reliabel dan akurat untuk menapis GCM pada pasien epilepsi dewasa.
Metode Penelitian. Penelitian dibagi menjadi 2 tahap. Tahap pertama meliputi adaptasi lintas budaya berdasarkan ketentuan World Health Organization (WHO), uji validitas isi berdasarkan penilaian pakar mengenai relevansi butir pertanyaan GAD-7 hasil adaptasi, dilanjutkan uji validitas interna, reliabilitas interna dan reliabilitas test-retest pada 30 pasien epilepsi yang memenuhi kriteria inklusi. Tahap kedua adalah uji diagnostik. Hasil GAD-7 dengan titik potong ≥7 dibandingkan dengan wawancara Mini International Neuropsychiatric Interview International Classification of Diseases-10 (MINI ICD-10) sebagai baku emas.
Hasil. Koefisien validitas isi berdasarkan metode Martuzua dari GAD-7 hasil adaptasi bahasa Indonesia adalah 0,847. Hasil uji validitas interna dengan korelasi Spearman didapatkan koefisien korelasi 0,648 hingga 0,800 (p<0,01). Uji reliabilitas konsistensi interna dengan Cronbach?s Alpha 0,867. Perbedaan nilai koefisien korelasi dan Cronbach?s Alpha antara pemeriksaan pertama dan retest menunjukkan reliabilitas test-retest yang baik. Dari 146 subyek uji diagnostik, prevalensi GCM hasil pemeriksaan MINI ICD-10 sebesar 16,4%. Dengan titik potong ≥7, GAD-7 memiliki sensitivitas 100% dan spesifisitas 84,4%.
Kesimpulan. Kuesioner GAD-7 versi Indonesia terbukti valid dan reliabel sehingga dapat digunakan untuk menapis GCM. Dengan titik potong ≥7, GAD-7 memiliki nilai akurasi yang tinggi untuk menapis GCM pada pasien epilepsi dewasa.
ABSTRACT Background. Generalized anxiety disorder (GAD) is one of the most common type among anxiety disorders in epilepsy population that can impaired patients quality of life. The Generalized Anxiety Disorder-7 (GAD-7) is a screening tool for detecting GAD that has been validated in epilepsy patients in Korea with cut-off point ≥7. The GAD-7 could be filled by the patients themselves in less than three minutes; hence, it is appropriate to be used in the neurology outpatient setting. The objective of this study is to obtain a valid, reliable, and accurate GAD-7 in Indonesian language as a screening tool of GAD in adult epilepsy patients.
Method. The study was conducted in two phases. The first phase included transcultural adaptation based on World Health Organization standards, content validity test based on expert consideration regarding the relevance of GAD-7 question items, followed by internal validity test, internal reliability test and test-retest in 30 epilepsy patients. The second phase was diagnostic test, in which, the GAD-7 with cut off point ≥7 will be compared with Mini International Neuropsychiatric Interview International Classification of Diseases-10 (MINI ICD-10) as the gold standard examination for diagnosing GAD.
Results. Content validity coefficient of GAD-7 adapted version based on Martuzua method was 0.847. Internal validity test with Spearman correlation obtained the correlation coefficient 0.648 to 0.800 (p< 0.01). Internal consistency reliability test with Cronbach?s Alpha was 0.867. The difference of correlation coefficient and Cronbach?s Alpha between the first and the retest showed good test-retest reliability. Out of 146 subjects of diagnostic test, the prevalence of GAD using MINI ICD-10 was 16.4%. With cut off point >7, GAD-7 had sensitivity 100% and specificity 84.4%.
Conclusion. The Indonesian version of the the GAD-7 was proven to be valid and reliable, also was found to be accurate as a screening tool for GAD in adult epilepsy patient with cut off point ≥7.;Background.
