title: The second-order factor structure of Cattell's 16 PF in patients with coronary heart disease.
abstract: The second-order factor structure of the 16 Personality Factor Questionnaire (16 PF) was validated on a sample of 940 patients hospitalized for coronary heart disease. The purpose of this investigation was the evaluation of second-order factor structure, already confirmed for normal subjects, of a selected pathological population. With factor analyses, oblique promax rotation, five second-order factors were identified, namely, Anxiety, Extraversion, Pathemia, Control, and an unidentified factor. These results were compared with those of Cattell's and Krug's studies. As a high congruence coefficient was shown, a good replication of Cattell's originally published second-order factors was achieved.
