Behavioral addictions are disorders of dependence or abuse linked to various behaviors or activities (without substance use), which are usually related to other psychological factors (low mood, social anxiety, self-control problems, etc.). They are defined as the loss of control over a behavior that leads to adverse consequences and a failure to resist the impulse to perform an act that is harmful to the individual. Furthermore, engaging in these behaviors produces a decrease in anxiety or a feeling of euphoria, causing significant interference in all areas of the person's daily life .

Although we often use the word addiction to define widespread and intense use, we must differentiate between problems related to addictive disorders and those stemming from use or overuse. As with substance addiction, young people who exhibit behavioral addictions, specifically those related to screens, may experience an increasingly strong need to engage in the addictive behavior, more frequently or for longer periods, and may exhibit withdrawal symptoms when deprived, characterized by discomfort such as sadness, irritability, and physical restlessness.
