Opening Reception and Poster Exhibition 139 Research shows that prevention programs that target youth between the ages of 8-12 may help increase life skills, thus lowering tobacco, alcohol and drug use. To measure these outcomes for the Health Rocks! program, two instruments from the University of Tennessee were selected: the healthy lifestyles scale and the decision-making scale. Both instruments were developed by expert panels as post-only measures. For this evaluation, the Cronbach’s alpha estimate of reliability for the Decision Making Scale (10 items) was .80 (N = 3,098). The Healthy Lifestyles Scale (6 items) had a Cronbach’s alpha of .81 (N = 3,098). The Healthy Lifestyles Scale was found to have a mean of 4.67 (σ = 0.555) while the Decision Making Scale had a mean of 3.83 (σ = 0.661). Our Likert type scale centers on a mean of 2.5 and so each scale shows positive responses from the participants.#Evaluation2009 #Alcohol,DrugAbuse,andMentalHealth #2009Conference #HealthEvaluation #ExtensionEducationEvaluation
