Effects of (very) brief writing on health: the two-minute miracle.

This study tested the lower boundary of the dosage required to garner health benefits from written emotional expression. Participants wrote about either a personal trauma, a positive life experience, or a control topic for 2 minutes each day for 2 days. Emotion word usage in the essays was examined and physical health complaints were measured 4-6 weeks after the last writing session. Trauma and positive experience essays contained more emotional content than the control essays and such content was of a similar percentage to that demonstrated by past research. Both the trauma and the positive experience conditions reported fewer health complaints at follow-up than the control condition.
