Public Health, Biostatistics, and Research Foundations

Psychiatric-mental health nurse practitioners (PMHNPs) need a robust comprehension of public health concepts such as social determinants of health and health equity. Mental health intricately intertwines with overall well-being, linking conditions like depression to heightened risks of physical ailments. PMHNPs frequently engage with vulnerable populations, necessitating health promotion strategies to mitigate mental health challenges exacerbated by socioeconomic factors. Proficiency in public health concepts empowers PMHNPs to advocate effectively for mental health needs, collaborating with stakeholders to promote awareness and access to care. Additionally, a working knowledge of biostatistics enables PMHNPs to critically evaluate research findings, inform evidence-based practice decisions, and contribute to research endeavors. Understanding research methodologies and statistical analyses facilitates the interpretation and application of research findings in clinical practice and policymaking. This chapter explores the indispensable role of public health, biostatistics, and research in informing PMHNPs’ practice, fostering evidence-based care delivery, and advocating for optimal mental health outcomes.
