A Large-Scale Test of the Goldilocks Hypothesis.

Area of Science:

• Adolescent health
• Digital technology impact
• Mental well-being research

Background:

• Concerns exist regarding negative associations between adolescent digital technology use and mental well-being.
• Previous research has not rigorously investigated these potential detrimental effects.
• Understanding the nuanced relationship between screen time and adolescent mental health is crucial.

Purpose of the Study:

• To rigorously examine the association between digital-screen time and mental well-being in adolescents.
• To investigate how the timing of digital technology use (weekday vs. weekend) influences this relationship.
• To provide evidence-based recommendations for adolescent technology use.

Main Methods:

• Analysis of data from a large, representative sample of English adolescents (n = 120,115).
• Utilized a preregistered plan for data analysis to ensure methodological rigor.
• Employed quadratic function analysis to model the links between screen time and mental well-being.

Main Results:

• The relationship between digital-screen time and adolescent mental well-being is best described by quadratic functions.
• The impact of digital technology use on mental well-being differs between weekdays and weekends.
• Moderate digital technology engagement was found to be not intrinsically harmful and potentially advantageous.

Conclusions:

• Adolescent mental well-being is not uniformly negatively impacted by digital screen time.
• The context and amount of digital technology use are critical factors influencing its effect.
• Findings support a balanced approach to adolescent technology use and inform future research methodologies.
