About
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.
Full description
Problematic Internet and smartphone use are a psychosocial phenomenon in which individuals pay too much attention to and rely on the Internet, negatively affecting their mental and physical health, lives, and work. Many studies have shown that problematic Internet and smartphone use can bring adverse psychological effects (e.g., depression, anxiety, and negative emotions) and unfavorable physiological conditions (e.g., poor sleep quality and memory loss). The negative psychological and physiological effects can result in adverse academic and work performance outcomes. Many existing studies mainly explore the underlying mechanism of problematic Internet and smartphone use from personal factors such as mental health, metacognition, coping strategies, personality traits, motivation, and attachment styles. However, more and more studies have begun to focus on the effects of environmental factors, such as peer relationships and parenting styles, on problematic Internet and smartphone use. To fill the literature gaps, formulate effective preventive and remedial interventions, and explore whether, when, and how environmental factors (e.g., child abuse and trauma, parenting behaviors, teachers' encouragement, and peer support) affect problematic Internet and smartphone use is crucial.
The previous psychological interventions for problematic Internet and smartphone use focused on cognitive behavioral therapy, sand-play therapy, family programming, group programming, counseling programming, and educational programming. Different types of interventions reduced the severity of problematic Internet and smartphone use to varying degrees. However, the existing intervention strategies ignore the perspective of positive psychology. In the country, some scholars proposed to discuss the self-regulation of addicts from the perspective of positive psychology and especially proposed a meaning-centered approach as an essential supplement to mainstream addiction therapy. Besides, some scholars have also noticed the role of positive psychological intervention factors, such as meaning in life and the formation and development of problematic Internet and smartphone use. Therefore, exploring the positive psychological intervention factors, especially the meaning in life and the construction and development of problematic Internet and smartphone use, is the starting point for developing evidence-based intervention strategies.
According to the Dynamic System Model of Developmental Psychopathology and the Interaction of Person-Affect-Cognition-Execution model, the present study will explore the underlying mechanisms from environmental factors (e.g., child abuse and trauma, parenting behaviors, teachers' encouragement, peer support) to problematic Internet and smartphone use by testing the mediator role and moderator role of personal factors (e.g., the meaning of life, social media flow), predominantly positive psychological intervention factors (e.g., character strengths). Therefore, the present study integrated positive psychological intervention factors into the dynamic system model of addictive behavior execution and applies it to explore the formation and development mechanisms of problematic Internet and smartphone use (see Figure 1 and Figure 2). In addition, this study will implement an interview and meaning-centered intervention program among middle school students to validate the validity of the dynamic system model of addictive behavior execution from the interpretation of qualitative material and intervention practices.
Given the research variables' diversity and complexity, the present study intends to include at least 500 adolescents over 12 years of age. The present study uses convenience and snowball sampling in mainland China and Hong Kong. The present study will also invite participants to accept longitudinal tracking. Participants willing to participate in the subsequent two surveys will provide their contact information. Before the research, the parents' and children's online informed consent forms will be obtained for the minors' sample. This questionnaire survey was completed in the preliminary stage of this study (approved: 2020-21-CIR8-3), and the intervention directions and techniques for problematic Internet and smartphone use were determined based on the questionnaire survey results.
Semi-structured Interviews:
The investigators will use a method of semi-structured interviews with open-ended questions to collect data. Individual interviews, lasting between 45 and 60 minutes, will be conducted and recorded. All participants should provide consent to participate before being interviewed. The interviews were conducted in Mandarin. All the materials used in the study (e.g., the recruitment information and questionnaires) were presented in Chinese. Thirty adolescents will be recruited to participate in the interviews.
Randomized Controlled Trial:
The investigators will pilot test the proposed meaning-focused intervention using a randomized (1:1) parallel-group controlled, single-blind trial in middle school students. The middle school collaborators will help launch the advertisement regarding this study, brief potential participants, prescreen potential participants according to recruitment criteria, and recruit participants using the opportunity sampling method. The participants' written informed consent will be obtained before conducting the intervention. One hundred adolescents will be recruited to participate in a randomized controlled trial. Four sessions will be delivered to the intervention group 1 week apart, with around 90 minutes per session.
Descriptive analysis and latent profile analysis will be adopted to present the overall situation of the research sample; psychology measurement attributes of the measures will be tested using confirmatory factor analysis; the correlation and regression analysis will be used to explore the relationships between environmental factors, personal factors, and problematic Internet and smartphone use. The structural equation modeling will be conducted to verify the mediator or moderator roles of positive psychological intervention factors in the relationship between environmental factors and problematic Internet and smartphone use.
