Data diuji dengan chi-square dan Kolmogorov-Smirnov, yang menggunakan chi-square yaitu hubungan tingkat pengetahuan dengan jenis kelamin (p=0,967), jumlah sumber informasi (p=0,140), dan sumber informasi paling berkesan (p=0,340). Hubungan tingkat pengetahuan pertolongan pertama dengan riwayat terkena DBD menggunakan Kolmogorov Smirnov(p=0,610). Hasil lain menunjukkan terdapat 29 orang (27,9%) memiliki tingkat pengetahuan baik, cukup 23 orang (27,1%) dan kurang 52 orang (50%).Perempuan berjumlah 61 orang dan laki-laki 43 orang.
