A Call For Integration Of Trauma-Informed Care Into Occupational Therapy: Improving Provider Competency Through A Case Study Of A Cooking Skills Program For Survivors Of Human Trafficking, Natalie Pravinkumar

OT Doctoral Capstones

Trauma, such as abuse, neglect, and violence, has evident lasting physical and mental health effects, such as chronic illness, behavioral changes, and depression. While trauma-informed care (TIC) helps providers recognize and respond to trauma, this training is often limited to mental health and social work fields. Many survivor populations never receive interventions designed with TIC in mind, restricting outcomes leading to reduced rehabilitation and reintegration.

Occupational therapy (OT) is fundamentally client-centered and functional, making it well suited for TIC. However, while they cover many similar topics, most OT programs do not include specific curriculum on TIC.
