Percentage Correct Responses1 to Survey Items on Knowledge about Tobacco Use Prevalence among Peers, High School Students, and Adults Among a Pooled 19 School Aggregate of 5th Grade Students in Western New York State who Received a Tobacco Prevention Program Intervention during the 1998–1999 School Year.

Survey Item:

Baseline Survey


(N = 1596)

Evaluation Survey

(Immediate Post-Test)

(N = 1438)




Epidemiological Knowledge of Tobacco Use:

(11) What percentage of kids your age (5th graders) use tobacco every week ....................



p < 0.0001

(12) What percentage of high school students (9th graders) use tobacco every week ..............



p = 0.0129

(13) What percentage of adults use tobacco every week ............................



p < 0.0001

1Proportions were compared at the School Level (N = 19), using Wilcoxon-Matched Pairs/Signed Rank Tests. P values were identified as significant if they were less than or equal to .05, thus rejecting the null hypothesis (that the Intervention had No Effect); n.s. = not significant. 2Percentages shown are Medians, which summarize the distribution of correct responses by school.
