For this study, “undergraduates (41 men, 41 women) wrote about supportive
ties or casual acquaintances. Supportive ties were rated as warmer and less
controlling than acquaintances, and writing about them evoked reductions in
negative affect, especially for low-hostile participants," the researchers said.
"Compared with the acquaintance condition, the supportive tie condition
resulted in reduced heart rate and blood pressure response during a subsequent
speech stressor” among low-hostile participants.

and women. Health Psychology, 2004;23(5):476-485.
