Ten students were randomly assigned to the expressive writing group and wrote about their thoughts and feelings associated with their most traumatic life events. Ten students were randomly assigned to the control group and wrote about their plans for the day. One month later, all of the students rated their overall level of physical health on a scale from 0 = very poor health to 100 = perfect health.
