A check on hypothetical personality structures and their theoretical interpretation at 14-16 years in T-data.

Basing hypotheses on interpretations of 12 personality factors most replicated in 10 past researches with children, this experiment sets up about eight subtests as specific markers for each. Ninety-five tests, taking eight hours in all, were administered to 394 14-16-year olds. A majority of the personality pattern hypotheses were sustained factor analytically by evidence on number of factors, significance of unique simple structure reached, and goodness of identifying match (chi-square test). Concept validities can be obtained for some six of the factors rivalling those for intelligence tests. A brief discussion is given of the bearing of the present results upon theoretical explanations of the given source traits, including extraversion, and it is pointed out that the psychological meaning of most, for personality research, is as important, in variance terms, as for the one or two, such as anxiety and extraversion, which have tended to monopolize discussion.
