Impulse Control Deficits and Loneliness/Depression: Central Aspects in Problematic Internet Use

Abstract

This study aimed to assess the prevalence of problematic internet use (PIU) among Brazilian adults and its cognitive and emotional factors. A total of 294 individuals (144 men, 149 women, 1 undisclosed) aged 18 to 55 years (M=29.31, SD=7.99) participated, completing various instruments: a sociodemographic and internet use questionnaire, the generalized problematic internet use scale (GPIUS-2), the online cognition scale (OCS), the depression anxiety stress scale-21 (DASS-21), and the difficulties in emotional regulation scale (DERS). The prevalence of PIU was 17.4% (n=49). Younger participants reported higher rates of PIU. GPIUS-2 scores positively correlated with DERS and DASS-21 subscales. Network analysis highlighted impulse control deficits and loneliness/ depression as key factors associated with PIU, with anxiety indirectly related through stress. These findings highlight the link between emotional difficulties and PIU, suggesting the need for guidelines to promote healthier internet use.
