The ZKPQ consists of 99 items measuring five basic dimensions of personality. It contains an additional Infrequency (Infreq) scale that allows eliminating participants with careless responding. The response sentence format is dichotomous with a true–false response set.
The personality dimensions measured are: Neuroticism-Anxiety (N-Anx), Activity (Act), Sociability (Sy), Impulsive Sensation Seeking (ImpSS), and Aggression-Hostility (Agg-Host).
