Personality disorders, characterized by enduring patterns of behavior, thinking, and feeling, significantly diverging from societal norms, pose complex challenges for psychiatric-mental health nurse practitioners (PMHNPs). Personality disorders often co-occur with other mental health conditions, including depression, anxiety, and substance use disorders. Despite their prevalence, personality disorders remain enigmatic due to their multifaceted nature influenced by genetics, environment, and culture. Stigmatization and media portrayal further complicate diagnosis and treatment efforts, contributing to misconceptions and under-recognition. Treatment hurdles persist, as entrenched patterns resist change, and pharmacotherapy options remain limited. However, evidence-based interventions like dialectical behavior therapy (DBT) offer promise, particularly for borderline personality disorder. PMHNPs play a crucial role in supporting individuals with personality disorders, facilitating symptom management, and enhancing overall well-being through education, therapy, and collaboration with families. This chapter provides comprehensive insights into DSM-5 personality disorder clusters, encompassing diagnostic criteria, pharmacological interventions, therapeutic modalities, and their respective implications for PMHNPs.
