The Research on Expressive Writing: Writing about Trauma
In 1983, James Pennebaker, a psychologist, then at Southern Methodist University, conducted, along with one of his graduate students, Sandra Beall, a study of forty-six college students. Students in one group—the experimental group—were instructed to write continuously for fifteen minutes about the most upsetting or traumatic experience of their lives. Their instructions included the following: In your writing, I want you to discuss your deepest thoughts and feelings about the experience. You can write about anything you want. But whatever you choose, it should be something that has affected you very deeply. Ideally, it should be something you have not talked [about] with others in detail. It is critical, however, that you let yourself go and touch those deepest emotions and thoughts that you have. In other words, write about what happened and how you felt about it, and how you feel about it now. In essence, these students were being invited to write about a time when something had fallen apart. Students wrote sitting alone in a small cubicle in the psychology building. They wrote on four consecutive days and did not sign their names to their pieces. These were not students who had been recruited because they were experiencing emotional or physical problems. These were ordinary college students recruited from introductory psychology classes. They wrote about the divorce of parents, about loss and abuse, about alcoholism and suicide attempts. They wrote about secrets. And in interviews conducted after finishing the four writing sessions, students actually reported feeling worse than they had before the writing. But four months later, these same students, compared to students who had written about trivial topics, reported improvements in mood and in outlook on life, and, perhaps most surprisingly, improvements in their physical health. When data came in from the student health center, it revealed that this same group of students had in fact visited the student health center for illness, on average, only half as often as their peers. This particular kind of writing—writing one’s deepest thoughts and feelings about trouble—is sometimes called expressive writing. And it’s the kind of writing about which much of the research on writing and health has been conducted. Since that early study in 1983, expressive writing has been tested in a wide range of settings. It’s been shown to improve self-reported health, psychological well-being, grade point average, and re-employment after lay-off. It’s been shown to benefit women with breast cancer, to decrease blood pressure in people with hypertension, to mitigate pain and fatigue in those with fibromyalgia, and to improve markers of immune function for those with AIDS. In an afterward to The Writing Cure, a compilation of research and theory published nearly twenty years after Pennebaker’s first study on expressive writing and health, he reflects on some of the implications of the body of research in the field. He writes: All of the evidence would suggest that writing brings about a general reduction in biological stress. That is, when an individual has come to terms with an upsetting experience, he or she is less vigilant about the world and potential threats. This results in an overall lowering of defenses. . . . Given the broad range of improvements in health outcomes, it would be prudent to conclude that writing provokes a rather broad and nonspecific...
