Targeting Impulsive Adolescents May Reduce Problem Drinking

A study reported by Medical News Today showed that young people with impulsive tendencies are more prone to drinking heavily at an early age. The study was conducted by scientists at the University of Liverpool.
The research suggests that targeting personality traits, such as impulsivity, could potentially be a successful intervention in preventing adolescent drinking from developing into problems with alcohol in later life. 

"Our results show that more impulsive individuals are more likely to start drinking heavily in the future compared to less impulsive individuals. The next steps are to take these results and apply them to prevention interventions that are tailored to individual characteristics, such as impulsivity,” said Professor Matt Field, from the University of Liverpool's Institute of Psychology Health and Society.

Previous research has suggested that impulsive behavior is linked with adolescent drinking, but it is unclear whether young people who are impulsive tend to drink more, or whether drinking while the brain is still developing is particularly harmful and can lead to the progression of impulsive behaviors. 

The team used computer tests that measured inhibitory control, the ability to delay gratification, and risk-taking. More than 280 young people who were aged 12 or 13 at the beginning of the study took part in the study. The participants repeated the computer tests every six months over the two years of the study. 

Results showed that those participants who were more impulsive in the tests went on to drink more heavily or have problems with alcohol at a later time. The study did not, however, show that alcohol consumption led to increased impulsive behavior on the computer tests. This suggests that there is a link between impulsivity and adolescent drinking, but that alcohol may not necessarily lead to increased impulsive behavior in the short-term.
