Auto-mutilation is a maladaptive coping mechanism and a major problem confronting behavioral medicine with no known treatment to date to place the behavior on complete extinction. The purpose of this experiment is to examine the possible beneficial effects of running relative to caffeine-induced SIB. Female Sprague Dawley rats (n = 4) served as subjects with each having a different extended baseline and treatment condition. Visual analysis of a multiple baseline graph did not support the hypothesis that as treatment (physical activity) was implemented SIB would decrease. It was found that subjects who drank more caffeinated water had higher amounts of activity in the running wheel. Also found was treatment may have increase auto-mutilation in subjects as opposed to decreasing SIB. This may be attributed to subjects experiencing a higher pain threshold after exercise.
