This study evaluated the effects of a community workshop designed to teach community members about human trafficking prevention. Participants were trained to identify the critical and non-critical features of human trafficking and safe ways to respond to identified trafficking situations. A pre-post treatment design was used to assess the effects of a community workshop across written and verbal target behaviors. This included written responses as well as simulation assessments across five different trafficking scenarios. Results indicate that all participants engaged in more correct responding within the written assessment and asked specific relevant questions with greater confidence within the simulation assessment following training. However, social media and empathy responses following the workshop did not differ from baseline. This study is one of the first empirical studies aimed at formally evaluating the effects of human trafficking prevention workshops. Results are discussed in the context of instructional design, measurement of outcomes, and interdisciplinary collaboration.
