Sensitivity analysis indicates that from both perspectives the service is very cost effective and may be cost saving .
CONCLUSIONS These results make alcohol screening and counseling one of the highest-ranking preventive services among the 25 effective services evaluated using st and ardized methods .
BACKGROUND The U.S. Preventive Services Task Force ( USPSTF ) has recommended screening and behavioral counseling interventions in primary care to reduce alcohol misuse .
This study was design ed to develop a st and ardized rating for the clinical ly preventable burden and cost effectiveness of complying with that recommendation that would allow comparisons across many recommended services .
The efficacy of single-session motivational interviewing in reducing drug consumption and perceptions of drug-related risk and harm among young people: results from a multi-site cluster randomized trial.
AIM To test whether a single session of motivational interviewing ( discussing alcohol , tobacco and illicit drug use ) would lead successfully to reduction in use of these drugs or in perceptions of drug-related risk and harm among young people . DESIGN Cluster r and omized trial , allocating 200 young people in the natural groups in which they were recruited to either motivational interviewing  ( n=105 ) or non-intervention education-as-usual control condition ( n=95 ) . SETTING Ten further education colleges across inner London . PARTICIPANTS Two hundred young people ( age range 16 - 20 years ) currently using illegal drugs , with whom contact was established through peers trained for the project . INTERVENTION The intervention was adapted from the literature on motivational interviewing in the form of a 1-hour single-session face-to-face interview structured by a series of topics . MEASUREMENTS Changes in self-reported cigarette , alcohol , cannabis and other drug use and in a range of drug-specific perceptions and other indicators of risk and harm . Measurement at recruitment and follow-up interview 3 months later . FINDINGS A good follow-up rate ( 89.5 % ; 179 of 200 ) was achieved . In comparison to the control group , those r and omized to motivational interviewing reduced their of use of cigarettes , alcohol and cannabis , mainly through moderation of ongoing drug use rather than cessation . Effect sizes were 0.37 ( 0.15 - 0.6 ) , 0.34 ( 0.09 - 0.59 ) and 0.75 ( 0.45 - 1.0 ) for reductions in the use of cigarettes , alcohol and cannabis , respectively . For both alcohol and cannabis , the effect was greater among heavier users of these drugs and among heavier cigarette smokers . The reduced cannabis use effect was also greater among youth usually considered vulnerable or high-risk according to other criteria . Change was also evident in various indicators of risk and harm , but not as widely as the changes in drug consumption . CONCLUSIONS This study provides the first substantial evidence of non-treatment benefit to be derived among young people involved in illegal drug use in receipt of motivational interviewing . The targeting of multiple drug use in a generic fashion among young people has also been supported
