Feasibility of Schema Therapy for Recurrent Depression in a Disaster Relief Worker with Prior Post-Traumatic Stress Disorder Treatment Using Prolonged Exposure Therapy.

This report presents the follow-up treatment course of a previously published case that demonstrated the effectiveness of prolonged exposure (PE) therapy for a disaster relief worker. The patient, a municipal employee in Fukushima Prefecture, developed post-traumatic stress disorder (PTSD) and mood disorders after the 2011 Great East Japan Earthquake and subsequent disasters. This follow-up focuses on the period from 2021 to early 2024, during which the patient experienced symptom recurrence after his father's death. This event revealed psychological patterns similar to his disaster-related responses. Schema therapy was introduced to address over-adaptive work behaviors and vulnerabilities in relationships, identified as relapse risk factors. Combined with antidepressants, schema therapy achieved sustained improvement. This longitudinal perspective demonstrates schema therapy's effectiveness in addressing underlying vulnerabilities when symptoms re-emerge after trauma-focused treatment. The findings underscore how initial trauma responses may interact with subsequent life events and suggest schema therapy's potential as a secondary intervention for disaster relief workers facing complex challenges.
