A new report has highlighted the significant difference that can be made by careful treatment of mental health conditions.
According to a paper published in the journal Alcoholism: Clinical & Experimental Research, as the membership of support and treatment group Alcoholics Anonymous (AA) increases, homicide levels decrease.
The conclusions were released alongside findings that there is a strong correlation between alcohol consumption rates and homicide in the US.
"These observations are also in agreement with recent studies of the effects of AA membership rates on deaths from alcohol-related liver disease and suicide," commented Robert Mann, senior scientist at the Centre for Addiction and Mental Health.
"They increase our confidence that we can achieve success in efforts to prevent or reduce alcohol-related problems."
Researchers added that the findings have confirmed the importance of looking for the underlying causes of mental health problems such as alcohol addiction in order to find solutions at a population level.
