Abstract
The aim of this study was to investigate the mediating role of deviant peer affiliation in the relationship between family functioning, specifically family cohesion and family adaptability, and internet addiction among Saudi adolescents. A sample of 946 Saudi Arabian adolescents with a mean age of 18.5 years (SD = 3.06) was obtained using snowball sampling. Path analysis using structural equation modeling was conducted. The results indicated significant negative relationships between family cohesion and internet addiction and between deviant peer affiliation and family cohesion, and a significant positive relationship between family adaptability and internet addiction. In accordance with prior research, we found a significant positive relationship between deviant peer affiliation and internet addiction, but in terms of mediation, deviant peer affiliation mediated only the relationship between family cohesion and internet addiction. In conclusion, it is important for the effectiveness of interventions and preventive programs that aim to address deviant peer affiliation and internet addiction in adolescents to enhance the well-being of their family systems.
