Determining Factors For Improved Uptake Of Harm Reduction Services In The United States: A Study Of Inclusive, Culturally Sensitive Messaging, Lauretta Ekanem Omale

Dissertations

Harm reduction refers to public health policies and programs aimed at decreasing the adverse consequences associated with drug use. While harm reduction services (e.g., syringe exchange programs) can mitigate health risks, marginalized groups face barriers to service access and utilization, partially due to ineffective messaging approaches that fail to align with cultural values and experiences. A one-size-fits-all approach to messaging can negatively impact service utilization, health outcomes, and health disparities. Ineffective communication can lead to poor adherence to treatment, poorer health outcomes, and increased adverse events.

Culturally insensitive communication contributes to stigma, mistrust, and lack of perceived relevance, discouraging service …
