Subjective wellbeing and longevity: Findings from a 22-year cohort study

OBJECTIVE The health implications of positive affect (PA) are still a matter of debate. The present study examined the longitudinal relationships between subjective wellbeing (SWB) components (i.e., Life satisfaction, PA and negative affect (NA)) and all-cause mortality in older adults. METHODS Discrete-time survival analysis within the structural equation modeling framework was applied to data from the PAQUID Cohort (n=3777, baseline age 62-101years) including ten time periods spanning 22years. Time-invariant (age, gender, baseline life satisfaction, diabetes mellitus and hypercholesterolemia status) and lagged time-varying (PA, NA, dementia, functional status and self-rated health) predictors were included sequentially in the analyses. RESULTS When included together in the model, only PA among the SWB components showed a significant association with longevity, which persisted (OR=.962, 95% CI=.938, .986) even after adjustment for the interaction between PA and NA, and after additional adjustment for prior medical conditions, functional status and self-rated health. CONCLUSIONS In congruence with positive psychology, PA proved to be an independent protective factor regardless of variations in NA, which did not seem to be a mortality risk factor.

The Geriatric Depression Scale: does it measure depressive mood, depressive affect, or both?

Self‐report measures of depression are highly important tools used in research and in various healthcare settings for the diagnosis of different levels of depression. The Geriatric Depression Scale (GDS) is the first and the most popular scale used to screen for late‐life depression. It is endorsed by the Royal College of Physicians and the British Geriatric Society (1992). The purpose of the present research was to investigate whether scores on the GDS15 capture depressive mood (i.e. trait depression), depressive affect (i.e. short‐term depressive state), or both.

Dyadic Cross-Sectional Associations Between Depressive Mood, Relationship Satisfaction, and Common Dyadic Coping

ABSTRACT The aim of this cross-sectional study was to investigate the mediational role of common dyadic coping in the links between depressive mood and relationship satisfaction. We estimated two competing Actor–Partner Mediator Models, in which the dyad is the highest unit of analysis. The first model specified dyadic coping as a mediator in the association between relationship satisfaction and depression, whereas the second model specified dyadic coping as a mediator between depression and relationship satisfaction. Analyzing data from 198 couples, our findings provided a plausible approximation of the second model, representing the interactional model of depression. They showed that common dyadic coping mediates the link between depression and relationship satisfaction for men only.

Decision-making in rectal and colorectal cancer: systematic review and qualitative analysis of surgeons’ preferences

Abstract Surgeons are experiencing difficulties implementing recommendations not only owing to incomplete, confusing or conflicting information but also to the increasing involvement of patients in decisions relating to their health. This study sought to establish which common factors including heuristic factors guide surgeons’ decision-making in colon and rectal cancers. We conducted a systematic literature review of surgeons’ decision-making factors related to colon and rectal cancer treatment. Eleven of 349 identified publications were eligible for data analyses. Using the IRaMuTeQ (Interface of R for the Multidimensional Analyses of Texts and Questionnaire), we carried out a qualitative analysis of the significant factors collected in the studies reviewed. Several validation procedures were applied to control the robustness of the findings. Five categories of factors (i.e. patient, surgeon, treatment, tumor and organizational cues) were found to influence surgeons’ decision-making. Specifically, all decision criteria including biomedical (e.g. tumor information) and heuristic (e.g. surgeons’ dispositional factors) criteria converged towards the factor ‘age of patient’ in the similarity analysis. In the light of the results, we propose an explanatory model showing the impact of heuristic criteria on medical issues (i.e. diagnosis, prognosis, treatment features, etc.) and thus on decision-making. Finally, the psychosocial complexity involved in decision-making is discussed and a medico-psycho-social grid for use in multidisciplinary meetings is proposed.

Dyadic Cross-Sectional Associations Between Negative Mood, Marital Idealization, and Relationship Quality

ABSTRACT This study aimed to evaluate (a) dyadic associations between relationship quality (RQ) and both depressive and anxious mood (DM and AM), (b) reciprocity hypotheses of negative mood within dyadic interactions, and (c) mediational role of marital idealization between negative mood and relationship quality. Actor-partner interdependence models (APIMs) were performed using data from a sample of 198 dyads. Our results showed that (a) these two facets of negative mood did not have the same weight on RQ and that they had a gender-specific effects pattern, and (b) there was no support for the mood transmission hypothesis. Mens DM displayed direct and indirect (via marital idealization) actor as well as partner effects on RQ, whereas womens DM displayed only a direct actor effect on RQ. There were no significant direct actor effects of AM on RQ, meaning that this link is fully mediated by marital idealization. However, only womens AM showed such indirect effects on RQ.
