In a variation on Pennebaker's writing paradigm, a sample of 81 undergraduates wrote about one of four topics for 20 minutes each day for 4 consecutive days. Participants were randomly assigned to write about their most traumatic life event, their best possible future self, both of these topics, or a nonemotional con- trol topic. Mood was measured before and after writing and health center data

Writing about life goals was significantly less upset- ting than writing about trauma and was associated with a sig- nificant increase in subjective well-being. Five months after writ- ing, a significant interaction emerged such that writing about trauma, one's best possible self, or both were associated with decreased illness compared with controls. Results indicate that writing about self-regulatory topics can be associated with the same health benefits as writing about trauma.
