Disclosure of traumas and immune function: health implications for psychotherapy.

Can psychotherapy reduce the incidence of health problems? A general model of psychosomatics assumes that inhibiting or holding back one's thoughts, feelings, and behaviors is associated with long-term stress and disease. Actively confronting upsetting experiences--through writing or talking-is hypothesized to reduce the negative effects of inhibition. Fifty healthy undergraduates were assigned to write about either traumatic experiences or superficial topics for 4 consecutive days. Two measures of cellular immune-system function and health center visits suggested that confronting traumatic experiences was physically beneficial. The implications for psychotherapy as a preventive treatment for health problems are discussed.
