The 252-item Pavlovian Temperament Survey-Revised (PTS-R) was adapted for English speaking countries and then administered to 622 subjects (315 female and 307 male). Items for the final 160-item version were selected on the basis of the criteria outlined by Strelau et al. (I 990; European Journal of Personality, 4, 209-235). A 78-item short form was also developed. Both inventories are scored on a 4-point Likert scale.
