Table 3 Percentage Correct Responses¹ to Survey Items on Knowledge about Tobacco Use Prevalence among Peers, High School Students, and Adults Among a Five School Aggregate of 5^th Grade Students in Western New York State who were Randomized² to Receive a Tobacco Prevention Program Intervention during the 1998–1999 School Year

Survey Item:	Baseline Survey (Pre-Test) (N = 450)	Evaluation Survey (Immediate Post-Test) (N = 408)		Follow-Up Survey t-Test (Delayed Post-test) (N = 371)
	Fall 1998	Fall 1998		Spring 1999
	%³	%³	p-value	%³	p-value
Knowledge of tobacco use prevalence:
(11) What percentage of kids your age (5^th graders) use tobacco every week ....	30.6	45.2	N.S.	29.3	N.S.
(12) What percentage of high school students (9^th graders) use tobacco every week .......	20.3	31.1	N.S.	20.4	N.S.
(13) What percentage of adults use tobacco every week ..................	4.8	33.9	p = 0.0313	11.5	N.S.

¹Proportions were compared at the School Level (N = 5), 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. ²There were 8 schools originally selected for this group; 1 school dropped out because they could not schedule the Intervention and another 2 schools were unable to schedule the Follow-Up (Delayed Post-Test) Survey, thus the data presented have complete information for each school at every measurement point. ³Percentages shown are the Medians, which summarize the distribution of correct responses by school.
