Assessing extraversion and emotional stability in adolescents: development and validation of a questionnaire

A reduced version of the Five-factor Personality Inventory, which only considers two of the five original dimensions, was constructed to assess Extraversion and Emotional Stability especially for a sample of 581 adolescents. This used Items 6, 9, 11, 19, 21, 39, 41, 46, 54, 59, 61, 66, 84, 89, 91, and 99. Exploratory and confirmatory factor analysis showed that the factor structure of the questionnaire is acceptable, and both scales are reliable and correlated with similar measures as The Eysenck Personality Questionnaire-Revised.
