Despite the development of effective interventions, up to 80% of young people with depression and anxiety serious enough to impact on their day to day functioning never get the support they need. E-mental health provides a potential solution and there is now a plethora of computerized and mobile phone interventions, although most lack evidence of effectiveness. SPARX is an evidence-based computerized intervention for depression for young people aged 12-19 years that utilizes a fantasy game format to deliver cognitive behavioural therapy in a self-help format. It has been available as a national service in New Zealand for the past three years with regular clinical monitoring. I will present results of the national roll-out, discuss lessons learned and present plans for the development of the next generation of intervention technologies in New Zealand.
