Emotional processing in vocal and written expression of feelings about traumatic experiences.

The purpose of this study was to compare vocal and written expression of feeling about interpersonal traumatic and trivial events in 20-min sessions over a 4-day period. Similar emotional processing was produced by vocal and written expression of feeling about traumatic events. The painfulness of the topic decreased steadily over the 4 days. At the end, both groups felt better about their topics and themselves and also reported positive cognitive changes. A content analysis of the sessions suggested greater overt expression of emotion and related changes in the vocal condition. Finally, there was an upsurge in negative emotion after each session of either vocal or written expression. These results suggest that previous findings that psychotherapy ameliorated this negative mood upsurge could not be attributed to the vocal character of psychotherapy.
