Abstract

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). The six scale scores showed adequate levels of internal consistency. Construct validity was supported by correlations with established personality measures. In Study 2 (n = 340), CFA results were cross-validated in an independent sample and construct validity was supported by correlations with BIS/BAS scales. In Study 3 (n = 317) test-retest correlations showed acceptable-to-good levels of temporal stability over a four-week interval. Results revealed a substantial overlap with original, full-length RST-PQ, providing evidence for the comparability of the two versions. Latent State-Trait analyses showed that the items of the RST-PQ-S mostly capture interindividual differences that are stable across situations. Taken together, findings indicate that the RST-PQ-S provides an efficient, valid and reliable alterative to the longer RST-PQ.

摘要

我们进行了三项研究（总共n  = 998），旨在开发和验证人格问卷的强化敏感性理论（即 RST-PQ-S）的简化版本。在研究 1 ( n  = 341) 中，根据理论和经验标准，从原始 RST-PQ 中选择了 22 个项目。对此简短表格的验证性因素分析 (CFA) 支持六因素结构，包括：FFFS、BIS 和四个 BAS 组件（奖励兴趣、目标驱动持久性、奖励反应性和冲动性）。六个量表分数显示出足够的内部一致性水平。结构效度得到与既定人格测量的相关性的支持。在研究 2 ( n = 340)，CFA 结果在独立样本中进行了交叉验证，结构有效性得到与 BIS/BAS 量表相关性的支持。在研究 3 ( n  = 317) 中，重测相关性显示在 4 周的时间间隔内时间稳定性达到可接受到良好的水平。结果显示与原始全长 RST-PQ 存在大量重叠，为两个版本的可比性提供了证据。潜在状态-特征分析表明，RST-PQ-S 的项目主要捕获在不同情况下稳定的个体间差异。总之，研究结果表明 RST-PQ-S 为较长的 RST-PQ 提供了一种高效、有效和可靠的替代方案。
