Ajzen and Fishbein's Theory of Reasoned Action was used to predict ado
lescents' behavioral intention regarding safe farm tractor operation.
A valid and reliable instrument was developed and was given to 235 Fut
ure Farmers of America (FFA) students from 10 schools in Illinois. The
single best predictor of adolescents' behavioral intention was the su
bjective norm (i.e., the respondents' perceived behavioral prescriptio
ns of friends and family members). Multiple regression determined that
adding behavioral norm to Ajzen and Fishbein's model significantly im
proved prediction of adolescents' behavioral intention regarding safe
farm tractor operation. The examples set by others play an important r
ole in determining the behavioral intent of respondents regarding farm
tractor safety. (C) 1998 National Safety Council and Elsevier Science
