Abstract
Recent research shows that the personality domain is better represented by six instead of five independent dimensions. The HEXACO-PI-R questionnaire adequately represents these six dimensions but is, because of the complexity of some items, less suitable for the assessment of people with lower educational levels and first-generation ethnic minorities. In this research, the construction of a simplified version of the HEXACO-PI-R, called the HEXACO-SPI, and the construction of an additional interstitial facet which purports to measure proactivity, is reported. In a sample of the Dutch population (N = 525), the HEXACO-SPI is found to have an adequate factor structure, reliable domain scales, more than adequate convergent validity and highly convergent construct validities when compared to the HEXACO-PI-R domain scales. Additionally, the interstitial proactivity facet is found to have the desired positive correlations with the HEXACO engagement factors and weak correlations with the HEXACO altruism factors.
