Examining the validity of the revised Reinforcement Sensitivity Theory scales

- This article summarizes the literature that uses r-RST measures.
- A critique of the strengths and weaknesses of each r-RST measure is given.
- This critique highlights important theoretical issues regarding r-RST.
- Researchers can use this article to assist in deciding which measure to use.
- It is hoped this article will stimulate and enrich discussions regarding r-RST.

Several self-report scales are now available to measure Gray and McNaughton's revised Reinforcement Sensitivity Theory (r-RST). To date, no research has evaluated all the studies used by these scales together in one article so researchers can assess their differential utility. This article attempts to address this issue with a summary of the studies used by the r-RST scales. We found that the Jackson 5 includes the most studies attesting to its validity, but recognize this as partly a function of it as the oldest scale. The Jackson 5 and the Reinforcement Sensitivity Theory Personality Questionnaire have been used by researchers other than the original authors, which suggests acceptance by the r-RST research community. Our hope is that this article is useful to researchers as a succinct summary of the validity of measures and also a commentary on the studies.
