The first steps will be to reach consensus on the reliable definition of the problem, devise age-appropriate assessment instruments to measure its severity, plan studies to clarify its clinical course and impact on health and quality of life as well as to clarify the underpinning brain-based mechanisms to support the development of screening biomarkers to identify those who are vulnerable before the problematic use becomes too entrenched, and ultimately to identify targets for treatment to guide the development of new and effective interventions.
A spectrum of usage, from controlled and “adaptive” to uncontrolled and “maladaptive”, is recognised. Some disordered online behaviours, such as excessive gaming, buying, gambling, email checking, social media use and viewing pornography, cause such significant impairment of everyday functioning of some individuals that mental health professional help is sought. National health authorities are now expressing concern. The most recent literature suggests that PUI is strongly linked with mental health disorders such as depression, anxiety, obsessive compulsive disorder (OCD) and attention deficit hyperactivity disorder (ADHD). However there is lack of agreement on the definition of PUI as a ‘mental disorder’ and a critical scarcity of reliable information on its prevalence, clinical parameters, brain-based biology and socio- health-economic impact.
