This study evaluated the psychometric properties of an on-line version of the
Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) by sex and
age. The questionnaire was responded by 1598 people, 474 males and 1124
females, with a mean age of 32.57 (SD = 11.72). Males and females differed in
their responses to all personality dimensions evaluated by this instrument, in a
similar way as that reported in past research. In addition, younger people
scored higher in the Aggressiveness factor, especially concerning the Physical
Aggression facet, whereas older people scored higher in the Activity factor.
Besides, younger people scored higher in the Neuroticism and the Sensation
Seeking factors, even though there were no age differences in the Extraversion
factor. The ZKA-PQ five-factor structure was clear and yielded high congruence
coefficients with the original Spanish validation sample. Altogether, the
findings support the validity of the online version of this instrument. The ZKAPQ
online version is therefore helpful in both, basic and applied research settings
about human personality and individual differences. |
