Symptoms of stress are prevalent among the homeless. Growing evidence suggests that disclosure of traumatic experiences is beneficial to health. This pilot study examined the effects of an emotional disclosure protocol on a group of 8 homeless people, using a single-group design. Clinical effectiveness was evaluated using the Impact of Event Scale, the Beck Depression Inventor, the Beck Anxiety Inventory, the Perceived Stress Scale, the Reading Span Task, and the Digit Span Test. Participant satisfaction was also measured. Results showed significant improvements in functioning at 1- and 6-week follow-up, and good satisfaction levels. The discussion remarks on the limitations (lack of a control group, small sample size, and other biases) and the need for more research in this topic.
