Abstract
Recent work has suggested that patients' coping could be improved in stressful dental situations if perceptions of self-efficacy and control could be enhanced. To test this hypothesis, 70 first-time third-molar extraction patients were randomly assigned to one of four surgery preparation conditions: standard preparation, oral premedication, relaxation, and a relaxation + efficacy-enhancing feedback condition in which subjects were given false galvanic skin response (GSR) biofeedback leading them to believe that they were highly skilled at relaxing. Analyses indicated that: (1) all treatments were seen as equally credible (controlling for placebo effects); (2) a priori contrasts showed that both the relaxation-only treatment and the relaxation + efficacy-enhancement treatment were superior to the premedication and standard preparations in raising coping self-efficacy; (3) regardless of treatment condition, increase in reported coping self-efficacy was significantly correlated with pre-operative anxiety, with self-reported peri-operative distress, and with behavioral ratings of peri-operative distress; and (4) the relaxation treatments resulted in lower pre-operative anxiety than the other interventions, and linear contrasts showed significant trends in which the relaxation + efficacy-enhancing condition was superior to the relaxation-only condition, which was in turn superior to the medication condition and the standard preparation in reducing both pre-operative anxiety and behavioral ratings of peri-operative distress. It was concluded that thoughts related to self-confidence and control can be manipulated, and that these thoughts can in part determine how well a person copes in stressful dental situations.
