Development and Validation of a Short Version of the Reinforcement Sensitivity Theory of Personality Questionnaire (RST-PQ-S)
We conducted three studies (total n = 998) aimed at developing and validating a shortened version of the Reinforcement Sensitivity Theory of Personality Questionnaire (i.e., the RST-PQ-S). In Study 1 (n = 341), twenty-two items were selected from the original RST-PQ, based on both theoretical and empirical criteria. Confirmatory factor analysis (CFA) on this short-form supported the six-factor structure comprising: FFFS, BIS, and four BAS components (Reward Interest, Goal Drive-Persistence, Reward Reactivity, and Impulsivity).
