Profile population needs, resources, and readiness to address needs and gaps Monitor, evaluate, sustain, and improve or replace those that fail Mobilize and/or build capacity to address needs Implement evidence-based prevention programs and activities Develop a Comprehensive Strategic Plan SAMHSA’s Strategic Prevention Framework Assessment Evaluation Capacity Planning Implementation

What Do Programs Want To Do? Assess Evaluate Select a Strategy Implement Develop Capacity
What Do Programs Want To DoWhen They Are Required to Evaluate? Assess Evaluate Select a Strategy • The quality of delivery. 2. The effects achieved. Implement Develop Capacity
What Do We Mean: Quality Of Delivery? • Dosage • How much? • How often? • Adherence • Was the program delivered as intended? • Was new content added? • Was important content deleted or modified? • Relevance • Was the program engaging to participants? • Did the program meet participants’ needs?
Dosage 1 • Meta-analysis of 25 SAMHSA model programs. • Programs that were delivered more frequently, generally had larger effects.
Dosage 2 • Same 25 SAMHSA model programs • Programs that had more opportunities for contact were generally more effective.
Adherence • An evaluation of Life Skills Training • Observers rated the percent of objectives met and lesson points covered • High-fidelity classes (>60% adherence) did best.

Adherence • An evaluation of Life Skills Training • Observers rated the percent of objectives met and lesson points covered • High-fidelity classes (>60% adherence) did best.
Local Adherence • Drug Strategies assessed adherence of Life Skills Training implemented in Baltimore. • Teachers re-taught lessons they had previously delivered. • Observers rated adherence. • Teachers implemented 65% of objectives (Range = 45-100%). • Teachers implemented 58% of main points (Range = 38-93%).
Local Adaptation • All teachers made adaptations • 3.5 definable adaptations, on average, per observed session (range 1 to 7) • Overall, 63% of adaptations were judged to be negative
Helpful Adaptations • The addition of reading material, videos, and testimonials • Changes in methods to make them more interactive • Inclusion of examples for cultural relevance or interest
Important Correlates of Adherence • Teacher’s Understanding of LST (r=.784; p<.01) • Quality of Process (r=.663; p=.03) • Level of Experience (r=.756; p<.01)
Relevance • As part of the SAMHSA program meta-analysis, we coded relevance. • Three aspects of relevance were significantly correlated with outcomes:
Quality of Implementation Summary Data are needed to assess: • Whether a sufficient dose has been delivered • How closely delivery adhered to design • The relevance of implementation for participants Gathering and reporting data will improve quality of implementation.
Outcome Evaluation • Everybody is afraid of outcome evaluation. • Why? • No one likes to fail. • It is perceived to be mysterious, complex, and expensive. • Outcomes are not controllable. • It shows you are normal.
What Are Prevention Goals? The goal of prevention is not behavior change but either: • Non-behavior maintenance • Delay in onset • Reduce the intensity of use
How Do Programs Work? • All Programs are based on a logic model. • The program changes a mediator: • Characteristics of the participant (skill, motivation) • Characteristics of the social environment • Characteristics of the physical environment • Characteristics targeted for change affect behavior.
All Stars Logic Model Example All Stars Core targets: • Lifestyle incongruence (idealism) • Normative beliefs • Commitment • Bonding to school • Positive parental attentiveness
Motivation Attitudes Bonding Beliefs consequences Commitment Normative beliefs Lifestyle incongruence Personal Competencies Academic skills Decision-making skills Emotional self-regulation Goal setting skills Self-esteem Social Competencies Resistance skills Media literacy Communication skills Social problem solving skills Social skills Environment Availability, access, enforcement Alternatives Classroom management Family management Monitoring and supervision Positive peer affiliations Support and involvement Mediators in Prevention
The Easy Part ofOutcome Evaluation • Collecting survey data is easy. • After over 30 years development, there are: • Many measures for assessing alcohol, tobacco, drug use, and consequences of use. • Many measures for measuring mediators (risk and protective factors targeted for change).
What Do When Programs Succeed? Assess Evaluate Select a Strategy Implement Develop Capacity

What Do You Do When YouHave Not Yet Succeeded? Assess Evaluate Select a Strategy Implement Develop Capacity
Working Backwards Evaluate Implement Develop Capacity
How To Develop Capacity? • Two predictors of quality implementation: • Experience • Training
Experience Counts! • Teachers with more experience were: • Most adherent when the taught LST (r = .630) • More likely to meet objectives (r = .590) • More likely to cover major points (r = .756) • More likely to make positive adaptations (r = .577)
Training Counts, Too! • Teachers’ understanding of LST was strongly correlated with adherence (r = .784).
Improving Understanding • Program-specific training • Coaching and feedback • Independent study
Program-Specific Training • Introductory training • Basics of theory and methods • Technical assistance • Help with specific issues and adaptations • Booster training • When important questions are asked • Certification of Mastery • A process of demonstration and certification
Does Training Matter? • Video Training Project • Two conditions • 3-hour course without video • 3-hour course with video • Topic: Norm Setting • Knowledge pretest-posttest survey http://www.PreventionABCs.com
All Stars Certification of Mastery • Basic All Stars facilitator training • Implement one cycle of All Stars • Videotape implementation with feedback about mechanisms of delivery • Videotape implementation with feedback about interactivity • Implement Strategies for Success • Implement Parent Intervention • Complete online course (Prevention ABCs) • Videotape to demonstrate expert delivery • Improved student outcomes
Just-In-Time Support • New project • Life Skills Training • Emailed helpful hints just before you teach • Links to a streaming video demonstration • Recruiting test schools lindadusenbury@tanglewood.net 1-888-692-8412
Conclusion • I was asked to answer two questions: • How can prevention programs use data to improve program effectiveness? • How can programs become data-driven?
Improving Effectiveness • How can prevention programs use data to improve program effectiveness? • Quality of implementation data • Behavioral outcome data • Targeted mediating variable data • All improve the potential of a program to be implemented with greater rigor
Improving Effectiveness • How can programs become data-driven? • Collect data • Look at the data you have collected • Start with modest expectations • Find meaning in the data • Find alternatives in the data
