The use of image habituation training with post-traumatic stress disorders.

An exposure treatment for patients suffering from post-traumatic stress disorder (PTSD) is described. Image habituation training (IHT) involves the patient in generating verbal descriptions of the traumatic event and recording these onto an audiotape. After the initial training session with the therapist, homework sessions of self-directed exposure in which the patient visualised the described event in response to listening to the audiotape were carried out. Of ten consecutive patients who received this treatment, six improved considerably after ten homework sessions, two showed moderate improvements, and two showed minimal improvement on a range of outcome measures. There were significant decreases in anxiety between and within homework sessions, suggesting that habituation did occur and was responsible for improvement. Treatment gains were maintained at six-month follow-up.
