Q-technique methodology in the study of healthy aged men: Part I

The paper describes the application of the Q-technique to the study of healthy aged men. The research is an NIMH project, and the Q-technique was performed on the initial study done in 1957 (47 Ss across 550 variables). The paper focuses on clusters of interdisciplinary relationships which contained biological and cognitive influences. Twenty-eight out of the 64 clusters fell within this category. This first paper concentrates on methodological precedures and issues, and also presents 6 clusters of output derived from the first two Q-factors. The remaining 22 clusters will be described in subsequent papers.
