Currently little research exists examining the theoretical underpinnings of self-mutilation (SM) in community samples of adolescents. Two models, the hostility and anxiety reduction models, were simultaneously tested in order to determine whether SM in adolescence was characterized by greater feelings of anxiety and hostility.

Hostility has been associated with heightened proinflammatory activity. However, it is not known whether greater hostility contributes to greater inflammation by promoting higher Th1 activity, lower Th2 activity, or both.

Our objective was to determine whether the pattern of BP change and the slope of the morning BP surge were related to hostility. The subjects were 32 patients with a history of Stage 1 hypertension. The morning surge in BP was derived from ambulatory B...
