I strongly endorse many of the suggestions made by the authors of the extremely useful reviews in this issue. In particular, the need to identify the complex causal mechanisms underlying the major health risk factors requires urgent attention of the research community. I suggest considering the important role of emotional disturbances as contributors to health risks given the empirically established comorbidity between mental and somatic illness. Better knowledge of these mechanisms is an essential prerequisite to develop tailored personalized prevention and (...) intervention programs, including reliable and valid assessment of deficits.

High-quality social relationships predict a range of positive health outcomes, but no broadly accepted theory can explain the mechanisms of action in this area. The central argument of this article is that affective science can provide keys for integrating the diverse array of theoretical models concerning relationships and health. From nine prominent theories, we cull four components of relational affect that link social resources to health-related outcomes. This component model holds promise for integrating research from the different theoretical perspectives and (...) for generating new, mechanistic questions about the connection between relationships and health. The article closes by outlining three empirical study ideas that illustrate ways in which the different components can be studied together in the context of mechanism-focused research. (shrink)

Hernandez et al.’s review provides clear evidence that positive affect can contribute to well-being and fits nicely within the positive psychology framework. The emergence of positive psychology has been valuable for understanding well-being, but I suggest that a balanced psychology can prove even more valuable in the years to come. A balanced psychology requires giving as much attention to negative emotion as to positive emotion. It also requires considering whether there are circumstances in which positive emotions can be detrimental and (...) negative emotions can be beneficial. Along those lines, evidence reviewed here indicates that healthy coping with severe stressors involves experiencing a combination of positive and negative emotions. (shrink)
