Reinforcement Sensitivity Theory of Personality Questionnaire: Measurement and Structural Invariance Across Age and Gender Groups

Revised reinforcement sensitivity theory (r-RST) of personality is a major neuropsychological theory of motivation, emotion, and personality. To measure the specific components of r-RST, the Reinforcement Sensitivity Theory of Personality Questionnaire (RST-PQ; Corr & Cooper(Psychological Assessment 28(11), 1427–1400, 2016) has been developed. The current study examined the measurement (configural, metric, scalar, and residual) and structural (factor variances, covariances) invariance across gender and age groups for an exploratory structural equation modeling (ESEM) version of the theorized six-factor oblique model. A total of 901 adults (M = 32.07, SD = 16.38) from the general community completed ratings of the RST-PQ. Multiple-group confirmatory factor analysis (CFA) supported full measurement and structural invariance. There was also no difference for the six latent mean scores across gender and age. The psychometric and practical implications of the findings are discussed.
