Revised Reinforcement Sensitivity Theory (r-RST) is a neurobiological theory of personality which has many differences compared to the original version. This highlights the need for measurement scales to reflect the revised theory. Study 1 uses exploratory and confirmatory factor analysis to develop and test new scales (the ‘Jackson-5’) which are shown to be internally reliable, have scale inter-relationships matching theory, and to have desirable construct validity properties. Study 2 compares r-RST with original RST in the prediction of delinquency and psychopathy in students. Results suggest the new scales capture the main properties of r-RST and indicate that r-RST provides a substantially different explanation of the personality basis of dysfunctional behavior compared to original RST.
