Educational intervention for the prevention of internet addiction disorder among 15-19-year-old adolescents in Colombo district, Sri Lanka.

Introduction: Internet addiction disorder is growing as a potentially problematic condition, especially among adolescents. Nonetheless, the condition is widespread and problematic, limited scientific evidence is available on the prevention, and efficacy of the treatment globally as well as locally. Objectives: The objective of this study was to determine the effectiveness of the developed educational package for the prevention of Internet addiction disorder among 15-19-year-old adolescents in Colombo district.

Methods: The study was a quasi-experimental study to determine the effectiveness of an educational intervention for the prevention of Internet addiction disorder. The educational package was developed on Social Cognitive Theory. The contents were designed following a literature review, expertise from a multidisciplinary panel, and using the preliminary results of the descriptive cross-sectional study. Adolescents from two educational zones in Colombo district were purposefully selected for the Intervention group (n=280) and control group (n=290). A self-administered questionnaire including a validated Internet Addiction Test(IAT) Sinhala version was used for the data collection. Following the implementation of the educational package, primary and secondary outcomes were compared between study groups by chi-square test and paired t-test using the SPSS-21 version.

Results: Following the intervention, the proportion of adolescents with Internet addiction disorder in the intervention group was less in comparison with the control group and the difference was statistically significant (χ2=9.026, df=1, p=0.003). There was a statistically significant difference between the mean differences of pretest and post-test IAT scores (t=-0.412, df=279, p=0.001) with the reduction of mean IAT scores among the intervention group. The proportion of study participants engaged in social media (χ2=10.6,df=1, p=0.001) and excessive engagement in internet gaming (χ2=5.514, df=1, p=0.019) among the intervention and the control groups revealed a statistically significant difference in favor of the intervention group.

Conclusions: The developed educational package was found effective for the prevention of Internet Addiction Disorder and recommended to use in future prevention programs and to aid the policymakers and administrators in the prevention, diagnosis, and management of Internet addiction disorder among this age group.
