Tackling the 'digital pandemic': The effectiveness of psychological intervention strategies in problematic Internet and smartphone use-A meta-analysis.

Abstract

Problematic Internet and smartphone use is associated with serious mental health problems. We thus investigated the effectiveness of psychological interventions on problematic Internet and smartphone use. We conducted a systematic review and meta-analysis and searched in PubMed, PsyArticles, PsycInfo, Medline and Google Scholar for peer-reviewed experimental and quasi-experimental research published between 2008 and 2021. A total of 10 studies accompanied by 14 effect sizes were included in the meta-analyses for problematic Internet use and 3 studies accompanied by 4 effect sizes for problematic smartphone use. The total sample size was n = 1439 with a mean age of 20.34 (SD = 6.63) years. Psychological interventions were effective for both problematic Internet use (g = -1.41, 95% confidence interval = [-1.90, -0.91], p < 0.001) and problematic smartphone use (g = -0.40, 95% confidence interval = [-0.79, -0.01], p < 0.001). Current evidence indicates that psychological interventions can be effective in reducing problematic Internet use/problematic smartphone use. However, the results must be considered preliminary due to the limited number of studies available in the respective fields.
