Despite astronomical healthcare costs in the U.S., patient outcomes remain suboptimal. While physicians are well-trained in biomedical care, they lack preparation in psycho-behavioral, non-pharmacological illness management. Patients who are served in primary care may be particularly affected by these gaps, as it serves as the de facto mental healthcare system and specialty referrals may be unavailable or poorly pursued, while many patients distrust or cannot afford pharmacotherapy. Though physicians recognize psychosocial and behavioral factors in illness, they are often unprepared to discuss these mechanisms or offer strategies beyond prescriptions and referrals. As chronic symptoms persist or worsen, patients return to care frustrated and physicians respond with more tests, referrals, and medications. These efforts increase financial burdens and risks without resolving symptoms. Amid economic, social, and political pressures, medicine must embrace patient-centered, culturally informed, non-pharmacological interventions. Such approaches reduce costs and improve care. Yet, given clinical demands, interventions must be brief and offer practical, clear steps to support physician-patient discussions and engagement. This book addresses gaps in care by offering concise, actionable non-pharmacological strategies for psychiatric and chronic pain conditions—areas where sustained symptom relief often depends on more than medications.
