A psychometric investigation of the Eysenck Personality Questionnaire.
The Eysenck Personality Questionnaire was administered to 139 females and 123 males. Scale statistics were obtained and hierachial factor analyses were performed. The P scale was found to have low internal consistency reliabilities and to covary with the L scale in the female subsample. Factor analyses showed recovery of E scale items in a secondary factor, Social Extraversion, without an impulsivity primary factor. No P and N dimensions recovered; rather components of each scale interrelated in two meaningful dimensions at the tertiary level.
