Twin Study Suggests Screen Time's Link to Mental Health May Be Overstated

A new study from Karolinska Institutet published in Nature Human Behaviour reveals that shared family factors—including genetics and upbringing—likely explain much of the association between high screen use and mental health problems in young people. Rather than screen time being the primary cause of mental health issues, the research suggests that genetic predisposition and family environment play substantial roles in this relationship. This finding challenges the common assumption that excessive device use directly causes anxiety and depression in adolescents. The study's implications could reshape public health messaging about screen time and mental wellness for Puerto Rican families.
