Abstract

P-technique, a method employing intra-individual correlation, is tried out for the first time. As part of the general design it uses some variables the same as those in a coordinated R-technique study and a second, parallel P-technique study with a clinical case. Definite factors are obtained among the psychological and physiological variables, which can be mutually matched. One is a fatigue factor, but the rest are general personality factors readily identifiable with those obtained in past R-technique researches.

What is set out in references (3) and (16) may be briefly summarized by saying that in R-technique we correlated test variables with regard to a series of persons; in Q-technique we correlate persons with regard to a series of tests. In P-technique we again correlate test variables, but with regard to a series of occasions and within a single person. Practically all factor analyses yet published have been in terms of R-technique and the remainder in Q-technique.
