Trauma assessment in outpatient psychotherapy and associations with psychotherapist's gender, own traumatic events, length of work experience, and theoretical orientation.

Our results suggest that trauma training lowers barriers and raises therapists' self-confidence in dealing with patients´ traumatic experiences. Therapists' characteristics effecting trauma assessment should be considered during training. Due to the increasing demand for psychotherapy, especially considering people with severe mental illness affected by traumatic events, trauma training should be obligatory for all mental health professionals.
