Q-type factor analysis was used to re-analyze baseline data collected in 1957, on 47 men aged 65-91. Q-type analysis is the use of factor methods to study persons rather than tests. Although 550 variables were originally studied involving psychiatry, medicine, cerebral metabolism and chemistry, personality, audiometry, dichotic and diotic memory, and social psychology--this report focuses on those Q factors which contain information on Wechsler Adult Intelligence Scale scores and various biological indices. The factors which were found to provide meaningful descriptions of these 47 subjects include: (1) full scale intelligence quotient; (2) lack of insight, as rated by psychiatrists; (3) blood pressure; (4) memory; (5) pulse rate; (6) hearing ability; (7) blood chemistry of the brain; (8) blood oxygen content; (9) blood glucose; (10) hemoglobin concentration; (11) history of angina pectoris; (12) social initiative; (13) oxygen-glucose ratio; and (14) electrocardiogram rating. (The usefulness of Q-type factor analysis is compared to R-type factor analysis, and extensive data tables are included.) (GDC)
