The aim of this study was to explore the relationships of the dimensions and facets of the Zuckerman–Kuhlman–Aluja Personality Questionnaire (ZKA-PQ) with other psychobiological personality measures: the EPQ-RS (Eysenck Personality Questionnaire Revised, shortened version), I7 (Impulsiveness Questionnaire) and SPSRQ-20 (Sensitivity to Punishment and Sensitivity to Reward Questionnaire, 20-item version). It is intended to test if findings reported with Zuckerman’s previous instrument (ZK-PQ) about the relationships between the three biologic-factorial personality models are replicated, giving evidence about the validity of the ZKA-PQ. The sample analyzed was of 584 subjects (50.3% men and 49.7% women) from the Spanish general population. Correlational and factor analysis supported the expected relationships between similar constructs assessed by the ZKA-PQ and the other questionnaires based on Eysenck’s and Gray’s personality theories. On the other hand, the inclusion of the facets from the ZKAPQ improved the validity of the questionnaire. Findings were discussed in the framework of the biological personality models, emphasizing the contribution of the ZKA-PQ to the psychobiological personality research.
