Abstract

This study aimed to adapt and validate the Spanish version of the Reinforcement Sensitivity Theory–Personality Questionnaire (RST-PQ; Corr & Cooper, 2016) and to demonstrate how RST constructs are associated with a variety of everyday behaviors. To achieve this goal, three studies have been conducted. In Study 1, a direct translation of the items from English to Spanish was pilot-tested in a sample of 139 students and a descriptive analysis of items was conducted. Moreover, a reverse translation and comparison between the two English versions were carried out by the lead author of the original questionnaire and the items were refined accordingly. In Study 2, the questionnaire’s internal structure was assessed using exploratory and confirmatory factor analyses and the predictive validity was assessed using the Criterion Set of Act Clusters in a sample of 1,281 participants. Finally, a study of convergent validity with other measures of personality was performed in Study 3 with 190 participants. The obtained results suggested that the RST-PQ has adequate psychometric properties and the convergent validity results with other personality measures replicate findings from previous research. Having a Spanish language version of the RST-PQ is important, not only to advance RST research but also to demonstrate that this theoretical approach contributes to the prediction and explanation of different behaviors whether they are healthy or pathological ones.
