This document is a compendium of how we have used the measures of bystander attitudes and behaviors that we have developed here at Prevention Innovations Research Center. Some of the versions of the measures have been researched more thoroughly in terms of psychometric properties than others. Please see the citations provided for articles that describe the versions of our measures that have been published. Here we simply provide a list of items that we have tried to use in different iterations of our work. We hope that it will help other researchers move the complex task of measuring bystander intervention forward.
