Effectiveness of Brief Intervention Widely Shown
The effectiveness of brief intervention has been widely studied. The analysis of the research evidence studied the results of 73 such studies. All focused on alcohol use among heavy drinking college students.
All were only one session. Researchers compared each study with usual treatment or no treatment.
The results were clear. Single session brief alcohol interventions, on average, greatly reduced drinking among college students. That is, who were heavy drinkers.
Analysts also studied motivational enhancement therapy motivational interviewing. They found it was more effective than psycho-educational therapy interventions.
The effectiveness of brief intervention has been clearly shown in research. Of course, short-term brief intervention effects were greater than long-term effects.
Why It Works
Brief intervention appear to be effective for two basic reasons.
First, they lead people to think about their use of alcohol. Is it helping them achieve their goals? Is it causing them harm in any way? Would they be better off reducing their drinking? Would they be better off drinking less often? And so on.
Second, brief intervention points them in the direction of learning skills to help them reduce their drinking.
The effectiveness of brief intervention is important. This is because traditional approaches to the problem have not proven very effective. In particular, efforts to promote alcohol abstinence among college students have consistently failed. Brief interventions reduce the problems of alcohol abuse. They do not entirely eliminate them. Nothing achieves that goal. But moving people toward safer drinking behaviors is a major achievement.
