Areas of Research Interests
Symptom appraisal in physical disease,
particularly psychological impediments and cues to seeking diagnosis for signs or symptoms.
Psychological predictors of nonadherence with cancer screening recommendations and medical treatments.
Dispositional and constitutional influences on health-related behaviors.
Sex differences in health and health behavior.
My research has focused on the role of stable dispositional characteristics that are associated with maladaptive health-related perceptions and behaviors. Initial studies found that individuals who scored low on measures of trait anxiety (i.e. who tend to be complacent in the face of threatening situations) took significantly longer than others to recognize the seriousness of developing cancer symptoms and thus seek help. On the other hand, those cancer survivors who scored high on the same measures of trait anxiety (i.e. who tend toward excessive worry and negative rumination) reported significantly poorer quality of life 2-5 years following treatment. Additional research has found that higher endogenous testosterone levels in males are associated with tendencies to minimize the significance of unfavorable health information. Findings from these studies will inform future efforts to educate and motivate the public toward more adaptive health-related behaviors.
