Smartphone Screen Time Study

Individuals diagnosed with conditions such as attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and depressive disorders tend to display levels of variable behavior disparate from their peers. Previous research has shown that variable behavior can be enhanced or reduced through reinforcement; however, the factors contributing to behavioral variability are poorly understood. Screen time has been hypothesized as a factor that may influence behavioral variability. The present study aimed to explore the possible relationship between smartphone screen time, behavioral

variability, and self-reported ADHD, ASD, and depressive symptoms
