Studies have evaluated the outcomes of sexual harassment training, but considerably less research has focused on variables that influence sexual harassment training effectiveness. To address this need, we developed and tested a model of individual and contextual inhibitors of sexual harassment training motivation to learn. Survey data collected from male and female participants across three time points were used to test the mediating role of pessimism about sexual harassment change in the relationship between sexual harassment myth endorsement and motivation to learn, as well as the moderating role of organizational tolerance for sexual harassment on the relation between sexual harassment myth endorsement and pessimism. Results were consistent with the hypotheses, and exploratory analyses also revealed unhypothesized sex differences. The strengths and limitations of the study, implications for practitioners, and directions for future research are discussed.
