Although many substance abuse prevention programs seek to enhance the
ability of adolescents to refuse offers of alcohol and other drugs, fe
w report assessments of refusal skill ability or its relationship to s
ubstance use. This report describes a procedure to assess the ability
of adolescents to refuse the offer of a beer, and presents the finding
s of those assessments as well as their relationships to alcohol misus
e prevention knowledge, susceptibility to peer pressure, internal heal
th locus of control, self-esteem, and alcohol use and misuse. A one-th
ird random sample (n = 1012) of 10th graders participating in a longit
udinal evaluation of an alcohol misuse prevention curriculum was asses
sed individually. Students rated their own refusals, which were also r
ated by trained female and male raters. The results indicated that ado
lescents refuse the offer of a beer only somewhat convincingly. Those
adolescents with better refusal skills had higher levels of alcohol mi
suse prevention knowledge, especially regarding resisting pressures to
use alcohol and the application of knowledge to typical alcohol-relat
ed situations. They also reported less susceptibility to peer pressure
, greater internal health locus of control and self-esteem, and less a
lcohol use and misuse. The results provide support for teaching refusa
l skills in substance abuse prevention programs and for assessing refu
sal skills in the evaluation of such programs.
