Banyard, V. L., Eckstein, R., & Moynihan, M. M. (2009). Sexual violence prevention: The role of stages of change. Journal of Interpersonal Violence apply Prochaska and DiClemente's Readiness for Change model to bystander intervention. They show that the stage of change an individual is in has an impact on bystander prevention related attitudes, behaviors, and impact of education programs. Do you use this model to inform your work? If so, how? What other theories of health behavior change guide the work you are doing?
