The factor analytic structure of seven physical CHD risk factors: a replication study.

An attempt was made to replicate the results of an earlier confirmatory factor analysis of the seven traditionally employed physical risk factors for CHD. As with the first investigation, a two-factor solution was confirmed; only family history loaded on factor 1; the remaining six risk variables (smoking, serum cholesterol, blood pressure, diet, exercise, and weight control) comprised factor 2. These findings may reflect a broad personality trait, i.e., generalized lack of self-control, which could underlie much CHD risk not associated with a family history of heart disease. Implications are drawn for research and practice in the areas of cardiac rehab and prevention.
