A 31-year-old female presents to the emergency department for the seventh time in four months with complaints of severe chest pain, shortness of breath, dizziness, and paresthesias in her hands. Each previous visit resulted in a comprehensive cardiac workup including ECG, troponin levels, chest radiography, and CT angiography on one occasion, all of which were negative. Her current presentation is identical to the prior six visits. ECG shows sinus tachycardia at 104 bpm, troponin is negative, and basic metabolic panel is normal. She is tearful and states she is 'certain something is terribly wrong' and feels she is 'going to die.' Review of her medical records reveals 22 emergency department visits across three hospital systems in the past year for various somatic complaints including abdominal pain, headaches, and neurological symptoms, all with negative workups. She has no established primary care provider or psychiatrist. Which assessment approach most appropriately evaluates this presentation?
