Community Prevention of Alcohol Problems: A Public Health Approach

Transcription

1 Community Prevention of Alcohol Problems: A Public Health Approach Harold D. Holder, Ph.D. Prevention Research Center Berkeley, California Observations Rarely are community prevention efforts evaluated we do not know if prevention is having any effect. Across the world, most of what is being done in community prevention will not produce population level effects-- --applying existing scientific evidence Prevention practice tends to implement popular and comfortable strategies avoiding those with evidence of effectiveness but difficult to implement.

2 Biggest Current Mistakes in Community Prevention? Doing many things that have little or no effect. 1,000 flowers bloom approach Not incorporating best prevention research into assessment, planning, and evaluation Action Traditional Approach to Prevention Desired Results PUBLIC SCHOOL EDUCATION BLACK BOX OF COMMUNITY BETTER FUTURE CHOICES FOR YOUTH ABOUT SUBSTANCES AND THUS REDUCED ABUSE Search for Action Systems Approach to Prevention Community System Desired Results X Z Y Q REDUCED HIGHWAY DEATHS RELATED TO DRINKING

3 Just What Is Environmental Prevention, Anyway? Environmental strategies in a community seek: 1. To bring about system-level change (including physical space, local community policies, availability of drugs and alcohol, etc.) in order 2. To reduce substance abuse problems at the population level. That is Public Health. Both conditions must be met. Outcomes-Based Prevention Substancerelated consequences and substance use Intermediate variables Programs/ policies/ practices Implementing the Strategic Prevention Framework Planning, Monitoring, Evaluation, and Replanning

4 Logic models are composed of: 1. Prevention goal, i.e., specific ATOD outcome to be reduced or changed 2. Intermediate variables or factors, which need to be changed (or considered) in order to achieve the goal 3. Intervention strategies to change intermediate variables. Example Logic Model for Substance Abuse Prevention What is wrong with this picture? Substance- Related Consequences Substance Use Intermediate Variables Strategies Alcohol- Related Traffic Crashes Among 15- to 24-Year-Olds Underage and Young Adult Binge Drinking Underage and Young Adult Driving After Drinking Youth 30-Day Cannabis Use Youth and Young Adult Lifetime Drinking School Bonding for Youth School Drug Resistance Training Awareness of Risk of Drinking Low Personal Self-Esteem Public Education About Drinking and Driving Risks Perceived Risk of Drinking and Driving Enforcement Youth Frequent Exposure to Internet Number of DUI Arrests Highly Visible DUI Enforcement Increased Abstinence Family Training Responsible Beverage Service To Reduce Overserving

6 Underage Drinking Logic Model Retailer training & rewards Compliance checks, citations, license loss Retail sale of alcohol to youth Discount bans Price Underage drinking laws Visible enforcement Party patrol, shoulder taps, beer keg registration Social availability of alcohol to youth (parties, peers, families) Underage drinking Local alcohol policy Community concerns about youth drinking Media advocacy Legal risks for providing alcohol to underage youth Examples of Effective Community Prevention Projects Utilizing Environmental Strategies

17 Evaluation

18 Evaluation and Monitoring = Measuring changes in outcomes and intermediate variables to determine if changes are going in desired directions. Provides management information (MIS) Determines strength (dosage) of intervention Enables changes in strategies and improvement Is good politics let local and State leaders see success Data and Effective Local Prevention Local prevention data is only useful if it directly helps improve local assessment, planning, and evaluation. Currently, few communities have the resources, technical ability, or skills to collect, analyze, and make full use of data to improve local prevention. How do we know what is needed for assessment, planning, and evaluation?

21 Summary Local environmental prevention can produce measurable results. Logic Model in environmental prevention must be based on empirical evidence about intermediate variables. Environmental strategies must be selected that have been shown to work that is, impact key intermediate variables. Do few things well. High dosage dosage to be effective.
