The present study will explore the underlying mechanisms of problematic Internet and smartphone use by focusing on how and when environmental factors affect the positive psychological intervention factors. Hence, the present study will provide scientific empirical evidence to design and formulate follow-up intervention strategies. Aims: I. Apply the dynamic system model of addictive behavior execution in Chinese adolescents with problematic Internet and smartphone use and use longitudinal data to track and explore the underlying mechanisms of environmental factors and personal factors on problematic Internet and smartphone use. II. Identify positive psychological intervention factors that effectively prevent and reduce problematic Internet and smartphone use according to the interview and provide empirical evidence for other intervention designs. III. Conducting a positive psychological intervention in an adolescent population to verify the protective effect of positive psychology factors on problematic Internet and smartphone use. Hypotheses: I. Environmental factors (e.g., child abuse and trauma, parenting behaviors, teachers' encouragement, peer support) will affect the problematic Internet and smartphone use through personal characteristics (e.g., meaning in life); II. The effect of environmental factors on problematic Internet and smartphone use through personal characteristics will be moderated by other positive psychological intervention factors (e.g., character strengths); III. Positive psychological intervention (e.g., meaning-based intervention, strengths-based intervention) is an effective intervention strategy to prevent and reduce problematic Internet and smartphone use.
