Wahyu Nanda Eka Saputra, Irvan Budhi Handaka

Abstract


Perilaku agresi merupakan salah satu masalah yang memiliki dampak negatif, terutama pada pencapaian hasil belajar siswa. Oleh sebab itu, perlu dikembangkan skala perilaku agresi yang dapat mengukur tingkat perilaku agresi siswa. Skala perilaku agresi sebelum digunakan perlu dilakukan uji coba untuk mengetahui validititas dan reliabilitasnya. Penelitian ini menggunakan korelasi product moment untuk menentukan tingkat validitasnya dan menggunakan rumus alpha cronbach untuk menentukan tingkat reliabilitasnya. Uji validitas dan reliabilitas skala perilaku agresi dibantu dengan aplikasi SPSS 16. Berdasarkan hasil analisis dapat disimpulkan bahwa dari 50 jumlah total item, 38 item diataranya dinyatakan valid dengan koefisien reliabilitasnya adalah  0,826 yang termasuk dalam kategori reliabilitas tinggi. Berdasarkan hasil analisis tersebut maka dapat dinyatakan bahwa skala perilaku agresi layak digunakan untuk mengukur tingkat perilaku agresi siswa. Seyogyanya konselor dapat memanfaatkan skala perilaku agresi ini untuk mengukur tingkat perilaku agresi siswa yang dijadikan data dasar membuat program layanan bimbingan dan konseling.
