BIG FIVE PLUS TWO: VALIDATION OF A SHORT VERSION

Abstract

The principal aim of the study was to develop a short version ofthe Big Five Plus Two Questionnaire (VP+2-70). On the basis ofcorrelations between the items contained in the integral version(184 items) and principal components of higher-order scales,seven 10-item scales were constructed. The construction of thisquestionnaire was conducted on a calibration sample of 2924participants (56% women), aged 18–68, while factorial stabilitywas examined on a validation sample of 802 participants (60%women), aged 18–60. Convergent validity was also examinedon these samples, by examining correlations between the VP+2-70 scales and scales of the Big Five Inventory. On a sample of374 university students, aged 19–33, relations between self- andpeer-ratings on the VP+2-70 were examined. Criterion validitywas explored by examination of relations between the VP+2-70scales and behavioral indicators contained in the The BehaviorReport Form – BRF questionnaire. This segment of the studywas conducted on a sample of 205 university students, aged18–29. The results point to satisfactory reliability as well as goodconvergent and criterion validity.
