Chapter 87: Primary Care Approaches to Behavioral Health

Advanced practice registered nurses and primary care providers encounter mental health concerns more commonly than many traditional medical diagnoses, necessitating the development of psychotherapeutic competencies alongside clinical medicine. The chapter emphasizes that adverse childhood experiences demonstrate a dose-response relationship with adult health outcomes, including both psychiatric symptoms and serious physical illnesses, and that prolonged stress activation through the hypothalamic-pituitary-adrenal axis creates physiological wear that extends beyond mood disorders. Cognitive behavioral skills building represents a practical, evidence-based framework for primary care implementation, incorporating cognitive restructuring to modify maladaptive thought patterns, behavioral activation to address anhedonia and motivational deficits, and skills training through behavioral experiments. Motivational interviewing provides a complementary approach grounded in understanding patient ambivalence and enhancing intrinsic motivation, utilizing open-ended questioning, affirmation, reflective listening, and collaborative summarization to facilitate behavioral change. The chapter highlights developmental considerations for pediatric and adolescent populations, where mental health onset typically occurs earlier than in adults and intervention language requires age-appropriate adaptation. By integrating brief psychotherapeutic modalities into routine primary care encounters, providers can address the social determinants and environmental stressors that drive health behaviors and disease trajectories, ultimately improving patient engagement and clinical outcomes while reducing the fragmentation inherent in treating physical and mental health as separate domains.
