A short questionnaire for the measurement of two dimensions of personality

Abstract

A 12-item questionnaire measuring neuroticism and extraversion was developed using a sample of 1600 adults equally divided into 8 groups on sex, an age dichotomy, and a social class index. Factor analysis yielded factors identical with those of a previous study. Statistically significant score differences were found on the 3 sampling dimensions, but only the sex differences were important. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
