Extraversion,neuroticism, and psychoticism in Iranian students1

A Persian translation of Eysenck's extraversion, neuroticism, and psychoticism inventory (PEN) was given to 209 university and 101 high school students in Iran. Comparisons of the mean scores on extraversion, neuroticism, and psychoticism between the two age groups do not show any significant differences, although the high school students appear to score higher than university students on all three personality dimensions. Comparisons of reliability estimates determined separately for the two age groups suggest that the PEN is equally reliable for high school and university students. The results are discussed in their cross-cultural context.
