Prostate cancer (PCa) patients often must decide between several treatment modalities considered equally efficacious, but associated with different benefits and side-effects. For some, the decision-making process can be difficult, but little is known about patient characteristics and cognitive processes that might influence the difficulty of such decisions. This study investigated the roles of dispositional optimism and self-efficacy in PCa treatment decision-making difficulty and satisfaction.
One hundred and twenty-five patients with clinically localized PCa completed a mail-in paper-and-pencil survey after they had made their treatment decision, but prior to treatment.
After adjusting for covariates, optimism and treatment decision-making self-efficacy were associated with less difficulty and greater satisfaction with the treatment decision-making process. Effects of optimism on difficulty and satisfaction were partially mediated by self-efficacy for making the treatment decision.
Men with PCa and who are low in optimism may be at greater risk for treatment decision-making difficulty and lack of treatment decision-making satisfaction, in part, because they have lower confidence in their ability to make the decision compared with those who are more optimistic. As self-efficacy perceptions are modifiable, consideration should be given to including self-efficacy enhancing components as part of PCa treatment decision-making interventions.

    • "Our results extend earlier findings regarding the construct validity and clinical utility of the RPT to a new population—oncology patients—and suggest that continued assessment of overdependence and detachment in this population may provide information regarding adjustment after cancer diagnosis. Obtained RPT-adjustment effect sizes in this sample were generally in the medium range, of a magnitude similar to that obtained in studies of personality and adjustment after cancer diagnosis involving other personality dimensions (e.g., optimism , locus of control; see Carver et al., 2005; Orom et al., 2009). These results are, in certain respects, consistent with earlier findings regarding overdependence and detachment in primary care patients , and they differ in certain respects as well. "

    ABSTRACT: Personality 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.

    ABSTRACT: Annually, about 500,000 children are coping with life-limiting illnesses. Many of these children could benefit from pediatric palliative care which provides supportive services. These services can also aid parents in decision making. In order to measure the effect of pediatric palliative care programs on decision making, a valid and reliable tool must be identified. This study aims to validate the psychometric properties of the Decisional Conflict Scale (DCS) and the COMRADE instruments for children with life-limiting illnesses. Analyses were conducted using survey data collected from 266 parents whose Medicaid enrolled children have life-limiting illnesses. Results of the analyses suggest that the DCS has better psychometric properties for measuring decision making within the population of children with life-limiting illnesses than the COMRADE. Pediatric palliative care programs should use the DCS to measure the effectiveness of services aimed at supporting families with high levels of decisional conflict.
