Hasil penelitian menunjukkan dari 21 item pertanyaan pengetahuan gizi terdapat 2 item pertanyaan yang tidak valid, 27 item pertanyaan Que CA terdapat 2 item yang tidak valid, 15 item pernyataan sikap gizi seimbang terdapat 2 item yang tidak valid, 13 item pernyataan perilaku gizi seimbang yang valid. Uji internal reliability pengetahuan gizi seimbang, pengetahuan Ques CA, sikap dan perilaku gizi seimbang (cronbachα = 0,687; 0,653; 0,680 dan 0,725 berturut – turut), eksternal reliability dengan test – retest pengetahuan gizi seimbang, pengetahuan Ques CA, sikap dan perilaku gizi seimbang (r = 0,564; 0,642; 0,233 dan 0,683 secara berturut – turut), tidak terdapat perbedaan secara signifikan rata – rata skor pada pengukuran test 1 dengan tes 2.
