The purpose of this study was to assess whether Indiana's private applicator training program affects private pesticide applicators' attitudes toward personal safety. The theoretical framework for this study was Ajzen and Fishbein's Theory of Reasoned Action. The sample was created by recruiting the enrollees participating in four private applicator training sessions selected at random. Sixty private pesticide applicators participated in a year long longitudinal study. Results revealed no significant improvement in positive attitudes toward pesticide safety was noted as a result of training. However, differences in attitudes toward pesticide safety were observed among selected demographic groups. Attitudes were most positive ten months after training indicating factors other than training were affective in developing positive attitudes toward pesticide safety. Selected factors other than training are discussed in relationship to attitude development. / Department of Natural Resources and Environmental Management
