Abstract

Empirical evidence suggests that there are marked associations between positive psychological states and health outcomes, including reduced cardiovascular disease risk and increased resistance to infection. These observations have stimulated the investigation of behavioral and biological processes that might mediate protective effects. Evidence linking positive affect with health behaviors has been mixed, though recent cross-cultural research has documented associations with exercising regularly, not smoking, and prudent diet. At the biological level, cortisol output has been consistently shown to be lower among individuals reporting positive affect, and favorable associations with heart rate, blood pressure, and inflammatory markers such as interleukin-6 have also been described. Importantly, these relationships are independent of negative affect and depressed mood, suggesting that positive affect may have distinctive biological correlates that can benefit health. At the same time, positive affect is associated with protective psychosocial factors such as greater social connectedness, perceived social support, optimism, and preference for adaptive coping responses. Positive affect may be part of a broader profile of psychosocial resilience that reduces risk of adverse physical health outcomes.

  • Higher baseline levels of positive psychological constructs, such as optimism and positive affect, are associated with greater subsequent improvements in health behaviors (and medical outcomes) in patients with type 2 diabetes and other chronic conditions, controlling for baseline physical activity, medical illness severity, and depression.

    “In contrast, higher baseline levels of positive psychological constructs, such as optimism and positive affect, are associated with greater subsequent improvements in health behaviors (and medical outcomes) in patients with type 2 diabetes and other chronic conditions, controlling for baseline physical activity, medical illness severity, and depression. 9-11”

  • These prior studies suggest a prospective and independent role of positive constructs on health behaviors, above and beyond the effects of medical variables and depression.

    The ‘Psychological Well-Being and Health Behaviors’ section reports associations between life satisfaction and behaviors including smoking and exercise. But the Conclusions say studies of behavioral mediators were largely cross-sectional and causal sequences had not been documented. The prospective findings, including effects that persisted after controlling for negative affect, concern health outcomes rather than an independent prospective effect on health behaviors after accounting for medical variables and depression.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
