Berdasarkan hasil pengukuran angket kepercayaan diri terjaring enam belas peserta didik teridentifikasi sebagai peserta didik yang memiliki karakteristik kepercayaan diri rendah. Pemilihan subjek untuk kelompok eksperimen dan kelompok kontrol dilakukan secara random dengan jumlah 8 peserta didik untuk setiap kelompok. Terdapat instrumen penelitian untuk mengukur angket kepercayaan diri yang memiliki nilai validitas butir pernyataan dengan nilai r tabel signifikansi 5% diatas 0,349 dan reliabilitas sebesar 0,903 sehingga angket kepercayaan diri reliabel dan layak digunakan sebagai instrumen penelitian. Data dianalisis dengan uji statistik nonparametrik Mann Whitney. Hasil uji hipotesis diperoleh nilai asymp Sig. (2-tailed) yaitu 0,012 < 0,05, maka  ditolak dan  diterima. Hasil uji N – Gain kelompok eksperimen sebesar 76% dalam kategori efektif. Sedangkan, untuk kelompok kontrol sebesar 43,90% dalam kategori kurang efektif. Hal ini diperkuat dengan uji independent sample T – test untuk N – Gain Skor dengan nilai Sig. (2-tailed) sebesar 0,005 < 0,05 yang menunjukkan perbedaan efektivitas yang signifikan antara kelompok eksperimen dan kelompok kontrol, sehingga    ditolak dan (2) diterima. Maka, terbukti bahwa konseling kelompok berbasis acceptance and commitment therapy efektif untuk meningkatkan kepercayaan diri pada peserta didik SMP.
