Effectiveness of a Group Cognitive-Behavioral Intervention for Problematic Internet Use Among Undergraduate Students in Nepal: A Quasi-Experimental Trial

Problematic internet use, using the internet in ways that interfere with daily life, is a growing concern among university students in Nepal, where studies report prevalence rates between 21.5% and 35.4%. Despite this, structured, evidence-based intervention trials in Nepalese academic settings remain scarce.

This study tested a six-session group program based on cognitive-behavioral therapy, which helps people change unhelpful behaviors around internet use. Sessions lasted 90 minutes and were delivered weekly by supervised Master's-level psychology students who completed 40 hours of CBT training, which the makes the program affordable and scalable for university settings.

Fifty-nine undergraduate students took part: 30 received the group program and 29 formed the comparison group. Both groups completed the Internet Addiction Test and the General Self-Efficacy Scale at five time points: before the program, immediately after, and at 2 weeks, 1 month, and 3 months later.

Students in the program showed significantly greater reductions in internet addiction symptoms than the comparison group immediately after the program (p = .049) and at 1 month, where a large effect was observed (d = -0.83, p = .003). At 3 months, the difference between groups was no longer statistically significant because the comparison group also continued to improve; however, the program group maintained a large reduction from baseline (d = 1.18). Students in the program also showed a significant increase in self-efficacy that remained stable through every follow-up (all p < .032). Adherence and acceptability were high: participants attended an average of 5.06 of 6 sessions, 80% attended at least 5 sessions, and satisfaction with the therapy reached 78.3% of the maximum possible score.

These findings suggest that a structured, group-based CBT program is an effective and acceptable approach for managing problematic internet use among Nepalese undergraduates and offers a potentially scalable framework for academic institutions in low-resource settings.
