RESUMEN
In this library-nursing initiative, the goal was to identify any changes in stigmatic perceptions among public library staff regarding mental health and substance abuse, post 3-day educational sessions. A total of n = 37 library staff participated in this project and attended all three educational sessions and completed a pre- and postquestionnaire designed to address common mental health and substance abuse-related stigmatic perceptions among public library staff. Upon analysis of the pre- and postresponses, we identified that there were statistically significant changes in two perceptions, namely; "embarrassed to disclose mental illness" and "commonality of substance abuse" (p ≤ .05). Therefore, it is essential that behavioral health nurses engage and collaborate with local public libraries to educate and build a safe environment for vulnerable populations like those affected with mental illness and substance abuse in the community settings.
