A group of researchers has developed a test to predict fourteen year old teenagers’ future drinking behaviour. The test takes a wide variety of factors that might influence young adults’ susceptibility to binge drinking into consideration such as family background, personality traits, availability of alcohol as well as brain-related variables. "There is no one really big thing. It's a bunch of little things adding up to give you this prediction," says Dr Robert Whelan from the University College Dublin. As of today, the test is far from practical as it lacks accuracy and relies on expensive brain scans. A more simplified and cost-effective version of the test could help identify at-risk adolescents for interventions in the future. Hugh Perry, chairman of the Medical Research Council Neurosciences and Mental Health Board, said further research could "lead to breakthroughs in this field and provide compelling evidence to inform public health policy and lay the groundwork for the design of interventions".
