Purpose of Review The COVID-19 pandemic changed people’s lifestyles and such changed lifestyles included the potential of increasing addictive behaviors. The present systematic review and meta-analysis aimed to estimate the prevalence of different behavioral addictions (i.e., internet addiction, smartphone addiction, gaming addiction, social media addiction, food addiction, exercise addiction, gambling addiction, and shopping addiction) both overall and separately. Recent Findings Four databases (PubMed, Scopus, ISI Web of Knowledge, and ProQuest) were searched. Peer-reviewed papers published in English between December 2019 and July 2022 were reviewed and analyzed. Search terms were selected using PECO-S criteria: population (no limitation in participants’ characteristics), exposure (COVID-19 pandemic), comparison (healthy populations), outcome (frequency or prevalence of behavioral addiction), and study design (observational study). A total of 94 studies with 237,657 participants from 40 different countries (mean age 25.02 years; 57.41% females). The overall prevalence of behavioral addiction irrespective of addiction type (after correcting for publication bias) was 11.1% (95% CI: 5.4 to 16.8%). The prevalence rates for each separate behavioral addiction (after correcting for publication bias) were 10.6% for internet addiction, 30.7% for smartphone addiction, 5.3% for gaming addiction, 15.1% for social media addiction, 21% for food addiction, 9.4% for sex addiction, 7% for exercise addiction, 7.2% for gambling addiction, and 7.2% for shopping addiction. In the lockdown periods, prevalence of food addiction, gaming addiction, and social media addiction was higher compared to non-lockdown periods. Smartphone and social media addiction was associated with methodological quality of studies (i.e., the higher the risk of boas, the higher the prevalence rate). Other associated factors of social media addiction were the percentage of female participants, mean age of participants, percentage of individuals using the internet in country, and developing status of country. The percentage of individuals in the population using the internet was associated with all the prevalence of behavioral addiction overall and the prevalence of sex addiction and gambling addiction. Gaming addiction prevalence was associated with data collection method (online vs. other methods) that is gaming addiction prevalence was much lower using online methods to collect the data. Summary Behavioral addictions appeared to be potential health issues during the COVID-19 pandemic. Healthcare providers and government authorities should foster some campaigns that assist people in coping with stress during COVID-19 pandemics to prevent them from developing behavioral addictions during COVID-19 and subsequent pandemics.

Background The increasing rate of problematic pornography use (PPU) among the general population has risen. There are limited data on the efficacy of Cognitive Behavioral Therapy (CBT) on online pornographic addiction; therefore, this study aimed at investigating the issue. Methods SCOPUS, PubMed, PubPsych, WOS (Web of Science), Cochrane Central Register of Controlled Trials, Google Scholar, Scientific Information Database (SID) & Iranmedex, and other databases (for gray literature) (eg, conference papers, key journals) will be systematically reviewed. Preliminary search strategies were started on March 2, 2019, and will be updated in April 2021. Eligibility criteria were having PPU, with designs of interest including randomized trials with three or more months of follow‐up with CBT intervention. Two authors will independently conduct data extraction and quality assessment. A modified Verhagen checklist for clinical trial studies will be used for quality assessment. Pooled measures of association will be computed using random‐effects model meta‐analyses. Between‐study heterogeneity will be assessed using the I2 statistic and the Cochrane χ2 statistic. Minor study effects will be evaluated for meta‐analyses with sufficient studies using funnel plots and Egger's test. If a meta‐analysis is appropriate, quantitative data will be pooled using the comprehensive meta‐analysis software. Discussion The evidence obtained in this meta‐analysis will help to determine whether CBT can decrease PPU severity, anxiety, depression, and compulsive sexual behavior. In addition, due to the comprehensive view on CBT effects on PPU patients, which was not clarified before, we can expect that the results of this study will benefit psychiatrists.
