AbstractPersonality traits have been associated with positive and negative adjustment to a cancer diagnosis. No studies have assessed trait dependency and detachment and their relationship to health, distress, and the doctor-patient relationship in patients undergoing radiation treatment for cancer. Fifty adults (32 women; mean [SD], 60.32 [12.74] years) undergoing radiation treatment for a variety of cancers completed measures of dependency and detachment, doctor-patient relationship, physical health, somatization, anxiety, and depression. Overdependence scores were positively and significantly correlated with patients' anxiety and negatively and significantly correlated with the physician-patient relationship. Detachment scores were positively and significantly correlated with pain, somatization, depression, and anxiety and marginally associated with lower health-related quality of life. These preliminary findings support the construct validity and clinical utility of trait dependency and detachment testing with oncology patients and suggest that detachment is associated with poorer quality of life and higher psychological distress, whereas dependency is associated with poorer doctor-patient relationships after a cancer diagnosis.
