Mental health professionals, especially those who work with traumatized individuals, are at risk of compassion fatigue and vicarious trauma. Continuous exposure to human suffering can cause emotional exhaustion, psychological distress, and affect their cognitive and relational functioning. Even with their expertise, these professionals are not immune to secondary stress. Vicarious trauma not only causes exhaustion; it can change one’s worldview, self-perception, and core beliefs, and reduce the ability to empathize with certain clients. This phenomenon is often underestimated or normalized, which slows down the implementation of preventive measures. However, validated self-care strategies, such as EMDR, can strengthen professional and personal resilience. This online course is only available in French.
