This 19 -week course prepares mental health professionals with the knowledge and skills to understand common trauma responses and to intervene using Cognitive Behaviour Therapy. While most affected individuals exhibit immediate reactions that typically resolve without severe long-term consequences, this has more to do with the resiliency and supports of the individual that to do with available trauma treatment. However, even those who show little impairment may still have subclinical symptoms or symptoms that do not fit diagnostic criteria for acute stress disorder (ASD) or PTSD. However, mental health professionals are faced with those clients who experience reactions across domains (emotional, physical, cognitive, behavioral, social, and developmental) associated with singular, multiple, and enduring traumatic events, all distressing to experience. Therapists are part of a larger network of caregivers that provide treatment for common stress disorders; to provide psychoeducation; to ‘normalize’ the experience for clients so as they do not attribute their symptoms to signs of weakness, being damaged, or going crazy; to use CBT in treating psychological symptoms; to communicate to client that rehabilitation is possible. Cognitive Behaviour Therapy is especially helpful in modifying cognitive errors that often accompany trauma responses. These cognitive errors include: excessive or inappropriate guilt; inaccurate rationalizations, idealizations, or justifications of the perpetrator’s behavior; trauma-induced hallucinations or delusions that, although biological in origin, contain cognitions that are congruent with trauma content; and intrusive thoughts and memories that can be inadvertently re-traumatizing. Cognitive Behaviour Therapy helps the client to develop coping strategies to deal with responses, to challenge automatic beliefs and to develop plans for alternative functioning.
