The current evaluation examined the effectiveness of the D.A.R.E. prog
ram in a rural Tennessee school system using self-report data on alcoh
ol/drug use. The evaluation was longitudinal in nature with data from
the first sample of controls (non-D.A.R.E. participants) collected in
1991, data from the second sample of controls collected in 1996 and da
ta from the experimental group (D.A.R.E. participants) collected in 19
96. Analysis of the self-administered survey response showed that sign
ificant differences existed only between the 1991 sample (n=253) and t
he entire 1996 sample for the frequency of both alcohol (p<.0001) and
drug use (p<.001). Comparisons between 1996 controls (n=93) and 1996 e
xperimentals (n=49) proved nonsignificant, as did all other comparison
s among the three groups. Results suggest that the factor of time betw
een 1991 and 1996 may be the causal element in the observed difference
s.
