Understanding the Construct of Positive Well-Being and Happiness

Increasingly, researchers attend to both positive and negative aspects of mental health. Such distinctions call for clarification of whether psychological well-being and ill-being comprise opposite ends of a bipolar continuum, or are best construed as separate, independent dimensions of mental health. Biology can help resolve this query--bipolarity predicts 'mirrored' biological correlates (i.e. well-being and ill-being correlate similarly with biomarkers, but show opposite directional signs), whereas independence predicts 'distinct' biological correlates (i.e. well-being and ill-being have different biological signatures). Multiple aspects of psychological well-being (eudaimonic, hedonic) and ill-being (depression, anxiety, anger) were assessed in a sample of aging women (n = 135, mean age = 74) on whom diverse neuroendocrine (salivary cortisol, epinephrine, norepinephrine, DHEA-S) and cardiovascular factors (weight, waist-hip ratio, systolic and diastolic blood pressure, HDL cholesterol, total/HDL cholesterol, glycosylated hemoglobin) were also measured. Measures of psychological well-being and ill-being were significantly linked with numerous biomarkers, with some associations being more strongly evident for respondents aged 75+. Outcomes for seven biomarkers supported the distinct hypothesis, while findings for only two biomarkers supported the mirrored hypothesis. This research adds to the growing literature on how psychological well-being and mental maladjustment are instantiated in biology. Population-based inquiries and challenge studies constitute important future directions. Copyright 2006 S. Karger AG, Basel

The purpose of this paper was: first, to develop the short six-item form of the Depression-Happiness Scale; and second, to examine evidence of reliability and validity for the short form. Three studies are presented. In the first study, principal components analysis is reported and used to select six items to compose the short form of the scale. In the second study, re-analyses of data from three previous studies are presented which confirm that the short scale has good psychometric properties of internal consistency reliability, test-retest reliability, and convergent and discriminant validity. In the third study, the short form is found to have a single component structure and convergent validity with measures of depression, happiness and personality.
