The integration of Islamic values includes gratitude, contentment, and trust that strengthen the spiritual dimension in the process of cognitive restructuring and behavioral change. The research method used is a quantitative approach with a true experimental pretest–posttest control group design. The research subjects were 20 students with high levels of FOMO who were divided into an experimental group and a control group. The research instrument used the Online Fear of Missing Out Scale (ON-FOMO). Data analysis was carried out using Paired Sample t-Test and Independent Sample t-Test. The results showed that Islamic value-based CBT is effective in reducing FOMO in students. This is indicated by the results of the Paired Sample t-Test which obtained a significance value of 0.001 <0.05, which means there is a significant difference between the pretest and posttest scores in the experimental group. In addition, the results of the Independent Sample t-Test showed a significance value of 0.001 < 0.05, indicating a significant difference between the posttest scores of the experimental and control groups. The effect size calculation results using Cohen's d of 2.48 are included in the very large category, indicating that the intervention has a strong influence in reducing FOMO in students. The conclusion of this study shows that Islamic value-based CBT is effective as an intervention in overcoming FOMO in students. This study provides theoretical and practical contributions to the development of Islamic guidance and counseling, particularly in the integration of the CBT approach with Islamic spiritual values to address psychological problems of adolescents in the digital era. date: 2026-03-13 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://digilib.uin-suka.ac.id/id/eprint/76325/1/24202021010_BAB-I_IV-atau-V_DAFTAR-PUSTAKA.pdf format: text language: id identifier: https://digilib.uin-suka.ac.id/id/eprint/76325/2/24202021010_BAB-II_sampai_SEBELUM-BAB-TERAKHIR.pdf identifier: Muhammad Ikhsan Fuadi, NIM.: 24202021010 (2026) EFEKTIVITAS COGNITIVE BEHAVIORAL THERAPY (CBT) BERBASIS NILAI ISLAM UNTUK MEREDUKSI FEAR OF MISSING OUT (FOMO) PADA SISWA KELAS XI DI MAN 2 YOGYAKARTA.
