Abstract

Researchers have suggested that the psychoticism (P) personality dimension of the Eysenck Personality Questionnaire may be largely redundant with the agreeableness (A) and conscientiousness (C) constructs of the five-factor model. Little research has examined the distinctiveness of these constructs. We utilized a multi-wave, multi-method design to examine the ability of C, A, and P to uniquely predict a number of important outcomes amongst high school students. A total of 778 students (391 males, 387 females; mean age 15.41 years.) completed personality measures in Grade 10. Self-reported self-esteem, social support, health-related behaviours, religious values as well as teachers' assessments of students, were collected 1 and 2 years later. A, C, and P were distinctive in their ability to predict these outcomes, after controlling for gender and socio-economic status as well as Grade 10 extraversion, openness, and neuroticism. The individual P items explained unique variance over and above that explained by A and C. It was concluded that P is not merely the opposite of A and C. Implications for interventions are raised.
