Research has indicated a correlation between lower self-esteem and decision making skills in children and increased drug use in later life. To promote the skills needed to make sound decisions regarding drug use and to develop general skills for healthy living, an alcohol and drug education program was presented to third and fourth grade pupils in 21 elementary schools in a large, urban school district of the Southwest. During the 1983-84 school year an evaluation of the program was conducted with 520 third and fourth grade pupils at five elementary schools. A measure of decision making and self-esteem was administered as a pretest, a posttest, and as a second posttest to a treatment group and to a comparison group. Grade-level repeated measures analyses of variance provided evidence of a group by time interaction effect on decision making and self-esteem at the third grade. An interaction effect was also found with respect to decision making at the fourth grade level. Post hoc tests did not locate significant mean differences, although trends in the data supported an effect of the program over time. (Author/JAC)
