An exposure‐based examination of the effects of written emotional disclosure

Abstract

OBJECTIVES: We undertook this study to clarify the operative mechanisms that account for the relationship between emotional disclosure and health. We hypothesized that emotional disclosure via writing was a form of exposure-based therapy and that exposure was the active therapeutic component. Design and method. A group of 129 male and female undergraduates were randomly assigned to three writing groups: (1) a trauma disclosure writing group; (2) a positive emotion writing group to control for affect arousal; and (3) a neutral writing group to control for any affect arousal - either positive or negative. Process measures were taken before and after each 3-day, 20-minute writing session. All participants completed questionnaires that assessed psychological and physical functioning at both the baseline and the end of the semester (approximately 9 weeks later). RESULTS: Groups reported differential affective arousal as well as disclosure themes in accord with our predictions. We did not replicate the findings of Pennebaker and his colleagues (e.g. Pennebaker & Beall, 1986). In our study, physical health outcome measures did not differ between groups by the end of the semester, nor did psychological measures change from baseline to follow-up. CONCLUSIONS: We found only limited support for the hypothesis that exposure best explains the effects of written self-disclosure. Implications for future research in this area are discussed.
