![]() Similar results were obtained using 1990 data after additional adjustment for depression (assessed by the Zung Self-rating Depression Scale).ĭispositional optimism is a relatively stable trait over 15 years and shows a graded and inverse association with the risk of cardiovascular death. The risk of cardiovascular death was inversely associated with increased tertiles of dispositional optimism (P <. Optimists in 1985 had a hazard ratio for cardiovascular mortality of 0.45 (top tertile vs lowest tertile 95% confidence interval, 0.29-0.68), adjusted for classic cardiovascular risk factors. Optimism scores significantly decreased over 15 years, but showed temporal stability (reliability coefficients, 0.72 over 5 years and 0.78 over 15 years P <. In Cox proportional hazards models, the first 2 years of observation were excluded. Dispositional optimism was assessed using a 4-item questionnaire in 1985, 1990, 1995, and 2000. In a cohort study with a follow-up of 15 years, we included 545 (61.4%) of 887 men, aged 64 to 84 years, who were free of preexisting cardiovascular disease and cancer and who had complete data on cardiovascular risk factors and sociodemographic characteristics. Dispositional optimism and pessimism are defined as personality traits characterized by tendencies to expect positive or negative outcomes in life (Carver. We aimed to determine whether dispositional optimism is a stable trait over time and whether it is independently related to lower cardiovascular mortality in elderly men. Controlling for known predictors of H&N cancer survival, pessimistic subjects (odds ratio, 1.12 95% confidence interval, 1.01 to 1.24) and those living alone (OR, 4.14 95% CI, 1.21 to 14.17) were more likely than optimistic subjects and those living with others to be dead at 1 year.Ĭonclusion: The results of this study of a cohort of French H&N cancer patients indicate that dispositional optimism predicts 1-year survival independent of other sociodemographic and clinical variables.Dispositional optimism, defined in terms of life engagement and generalized positive outcome expectancies for one's future, may be related to lower cardiovascular mortality. The multivariate analysis was performed on the data from the 96 subjects in whom 1-year survival status was known. Multiple regression analyses revealed dispositional optimism as a significant predictor of future depressive symptoms even after the effects of time 1 levels of depressive symptoms, negative affect, positive affect, daily hassles, and a hassles x positive affect interaction were controlled. ![]() Of these, 51 were alive at 1 year after diagnosis, 45 were dead, and five were lost to follow-up. Results: The sample size was 101 patients, representing all but one of those patients fitting the inclusion criteria who were diagnosed during the recruitment period. Zieliska-Wiczkowska (2017) demonstrated that financial standing had a significant impact on dispositional optimism in the University of the Third Age students she studied. The analysis of the hypothesized association between DO and 1-year survival was performed using multiple logistic regression analysis, controlling for other sociodemographic and clinical variables. Optimism levels were found to be associated with the women’s country of origin, professional activity, education, and treatment for emotional disorders. One-year survival status was collected on all subjects. Dispositional optimism (DO) was evaluated at baseline using a French version of the Life Orientation Test translated and validated for this study. Patients and Methods: A prospective observational study design was used with a cohort of H&N cancer patients diagnosed during the period from March 1, 1997, to August 31, 1998, at the Centre Hospitalier Universitaire, Clermont-Ferrand, France. Purpose: The aim of this study was to investigate the hypothesis that, independent of other known prognostic factors, pessimistic head and neck (H&N) cancer patients have a greater risk of being dead 1 year after diagnosis than do optimistic patients.
