| | Turning happiness into economic power |
 | | An example of a personality trait that can build psychological capital is conscientiousness, which, according to speaker Brent Roberts, PhD, a psychologist at the University of Illinois, Urbana-Champaign, improves both life expectancy and overall well-being. |
 | | Conscientiousness is one of the "Big Five" personality traits defined in the 1970s by psychologists Paul Costa, PhD, and Robert McCrae, PhD, of the National Institutes of Health, and Warren Norman, PhD, of the University of Michigan and Lewis Goldberg, PhD, of the University of Oregon (the others are extraversion, agreeableness, emotional stability and openness). |
 | | The study also indicates that conscientiousness increases over a person's lifetime, along with healthy behaviors, he said, and that improved well-being in each conscientious individual translates into an overall benefit to society, in the form of both happier citizens and lower heath-care costs. |
