Technological advances, together with the recent phenomenon of computer-mediated communication as an integral part of young people's lives, mean that traditional face-to-face delivery is not the only way to address mental health issues. There is now a rapidly developing e-spectrum of interventions that parallels, supports and substantially extends opportunities across the traditional spectrum. Debra Rickwood, Professor of Psychology at the University of Canberra and Head of Clinical Leadership and Research at headspace, Australia's National Youth Mental Health Foundation, believes the potential for the e-spectrum is undeniable. Here she examines the types of interventions being developed and their role in youth mental health, including the challenges and gaps that are becoming evident. (Contains 2 figures.)
