A Mixture Modeling of the Behavioral Activation System and Problematic Internet Use in Adolescents: The Role of Metacognition, Online Dissociation, and Insomnia

Due to the rapidly developing technological advancements, the overuse of the Internet has led to the emergence of problematic Internet use, which has become a part of our daily lives. This study aims to investigate the relationships between problematic Internet use, Behavioral Activation System (BAS), metacognition, online dissociative experiences, and insomnia. Participants were 341 Turkish adolescents aged between 15 and 19 years (Mean = 15.49, SD = 1.03), of whom 63% were female. Participants responded to the Behavioral Inhibition/Behavioral Activation System Scale, Metacognition Questionnaire, Van Online Dissociative Experiences Schedule, Insomnia Severity Index, and Chen Internet Addiction Scale. The mixture structural equation modeling approach was used to analyze the data. We found a positive relationship between BAS and metacognition, as well as insomnia, and a negative relationship with online dissociation. Furthermore, BAS was indirectly related to problematic Internet use via metacognition, online dissociation, and insomnia. The mixture analysis grouped participants into two latent classes. The first class (76%) had low levels of metacognition, online dissociation, insomnia, and problematic Internet use and high levels of behavioral activation while the second class (24%) had low levels of behavioral activation and high levels of metacognition, online dissociation, insomnia, and problematic Internet use. These findings indicate that individuals with high impulsivity, a tendency toward fun-seeking, and reward sensitivity are predisposed to excessively use the Internet and that metacognition, online dissociative experiences, and insomnia play a determining role in this behavior. © 2024 Scandinavian Psychological Associations and John Wiley & Sons Ltd.
