In this episode of The Research Files, we're joined on the line by Professor Helen Christensen, The Director and Chief Scientist at Black Dog Institute. Black Dog Institute is an Australian organisation focussed on identifying, preventing and treating mental illness. They’re also pioneers in mental health research, and one research area is concerned with suicide prevention. This area is named CRESP, which stands for the Centre of Research Excellence in Suicide Prevention and brings together key researchers to focus on projects and trials with the aim of lowering suicide rates. Professor Christensen is currently leading a phase of CRESP research – which she labels CRESP 2 – that aims to deliver suicide prevention strategies across the country, taking a technology-based approach. Their work will include intervening at both primary and secondary school levels, with strategies centring on the use of different smartphone apps.
