Little is known about the perception of lifetime risk for cardiovascular disease (CVD). Researchers recruited subjects from the Dallas Heart Study, and each subject was classified as high or low for risk of CVD. Subjects were then assessed for their perceived lifetime risk for a myocardial infarction. There was significant discordance between perceived and predicted lifetime risk.
Martin Seligman's multidimensional theory of psychological well-being, PERMA (positive emotions, engagement, relationships, meaning, and accomplishment), was empirically tested on a sample of Australian male students (age 13-18). Researchers selected a subset of theoretically relevant items from an extensive well-being assessment. Four of the fiver PERMA elements emerged from a factor analysis, along with two ill-being factors.
