Using cluster analytical procedure, this study aimed (i) to determine whether people could be differentiated on the basis of coping profiles (or unique combinations of coping strategies); and (ii) to examine the relationships between these profiles and perceived stress and health-related behaviors. A sample of 578 French students (345 females, 233 males; Mage= 21.78, SDage= 2.21) completed the Perceived Stress Scale-14 (Bruchon-Schweitzer, 2002), the Brief COPE (Muller and Spitz, 2003) and a series of items measuring health-related behaviors. A two-phased cluster analytic procedure (i.e. hierarchical and non-hierarchical-k-means) was employed to derive clusters of coping strategy profiles. The results yielded four distinctive coping profiles: High Copers, Adaptive Copers, Avoidant Copers and Low Copers. The results showed that clusters differed significantly in perceived stress and health-related behaviors. High Copers and Avoidant Copers displayed higher levels of perceived stress and engaged more in unhealthy behavior, compared with Adaptive Copers and Low Copers who reported lower levels of stress and engaged more in healthy behaviors. These findings suggested that individuals' relative reliance on some strategies and de-emphasis on others may be a more advantageous way of understanding the manner in which individuals cope with stress. Therefore, cluster analysis approach may provide an advantage over more traditional statistical techniques by identifying distinct coping profiles that might best benefit from interventions. Future research should consider coping profiles to provide a deeper understanding of the relationships between coping strategies and health outcomes and to identify risk groups. © The Author 2014.

This study aimed to determine whether the various factors of coping as measured by the Brief COPE could be integrated into a more parsimonious hierarchical structure. To identify a higher structure for the Brief COPE, several measurement models based on prior theoretical and hierarchical conceptions of coping were tested. First, confirmatory factor analysis (CFA) results revealed that the Brief COPE's 14 original factors could be represented more parsimoniously with 5 higher order dimensions: problem-solving, support-seeking, avoidance, cognitive restructuring, and distraction (N = 2,187). Measurement invariance across gender was also shown. Second, results provided strong support for the cross-validation and the concurrent validity of the hierarchical structure of the Brief COPE (N = 584). Results indicated statistically significant correlations between Brief COPE factors and trait anxiety and perceived stress. Limitations and theoretical and methodological implications of these results are discussed. Copyright © Taylor & Francis Group, LLC.

Background. Mortality prediction is crucial to select the optimal treatment in elderly cancer patients. Our objective was to identify cancer-related factors and Comprehensive Geriatric Assessment (CGA) fndings associated with 1-year mortality in elderly inpatients and outpatients with cancer. Methods. We prospectively included patients aged ≥70 years who had solid or hematologic malignancies and in whom the CGA was performed by geriatricians in two French teaching hospitals. We identified independent predictors of 1-year mortality after study inclusion, using multivariate Cox models stratifed on inpatient/outpatient status. We built three multivariate Cox models, since strong correlations linked activities of daily living (ADL), Eastern Cooperative Oncology Group Performance Status (ECOG-PS), and timed get-up-and-go test (GUG) results; and since physicians' preferences for these three assessments vary. A sensitivity analysis was performed using multiple imputation. Results. Of the 993 patients (mean age, 80.2 years; 51.2% men), 58.2% were outpatients and 46% had metastatic disease. Colorectal cancer was the most common malignancy (21.4%). Mortality rates after 6 and 12 months were 30.1% and 41.2%, respectively. In all models, tumor site and metastatic status (p < .001), age >80 years (p < .05), higher number of severe comorbidities (p < .05), and malnutrition (p < .001) were associated with death independently from impaired ECOG-PS (p < .001), ADL (p < .001), and GUG (p < .001). The adverse effect of metastatic status differed significantly across tumor sites, being greatest for breast and prostate cancer (p < .001). Multiple imputation produced similar results. Conclusion. The predictors of 1-year mortality identified in our study may help physicians select the optimal cancer-treatment strategy in elderly patients. © The Author 2015.
