The Reinforcement Sensitivity Theory of Personality Questionnaire (RST-PQ) originated from the Revised Reinforcement Sensitivity Theory of Personality. This study was conducted to assess the psychometric properties of the Persian version of the RST-PQ among a group of Iranian adults.
The cross-sectional study was carried out among 600 Iranian adults utilizing a convenient sampling method, following specific participant selection criteria to enhance the study methodology's transparency (including the age range between 18 and 35 years' participants without major psychiatric diagnoses). Participants completed both the Iranian version of the Reinforcement Sensitivity Theory Personality Questionnaire (RST-PQ) and the Five-Factor NEO-FFI questionnaire. Confirmatory factor analysis, employing the multiple indicators model (MIMIC) approach, was utilized in this study to control for demographic variables such as age and gender.
The confirmatory factor analysis results showed an acceptable fit of the proposed six-factor model based on the English version of RST-PQ (CFI = 0.905; RMSEA = 0.053). Also, Cronbach's alpha values confirmed the internal consistency of the proposed structure. In addition, competing models were also used to select the best-proposed model. In this way, different models were evaluated, assuming a change in the correlation intensity between BIS and the Fight-Flight-Freeze System (FFFS).
The convergent validity results with the Five-Factor Personality measure provided further support and were consistent with previous research findings. It is crucial to have an Iranian-language version of the RST-PQ to promote RST research and show how this theoretical framework aids in explaining and predicting various actions, whether they are abnormal or healthy.
人格的强化敏感性理论问卷（RST-PQ）源于修订后的人格强化敏感性理论。本研究旨在评估伊朗成年人中 RST-PQ 波斯语版本的心理测量特性。
本横断面研究采用便利抽样法在 600 名伊朗成年人中进行，根据特定的参与者选择标准（包括年龄在 18 至 35 岁之间且无重大精神诊断的参与者），提高研究方法的透明度。参与者完成了伊朗版的强化敏感性理论人格问卷（RST-PQ）和五因素 NEO-FFI 问卷。本研究采用多指标模型（MIMIC）方法进行验证性因素分析，以控制年龄和性别等人口统计学变量。
基于 RST-PQ 的英文版本，验证性因素分析结果显示出六因素模型具有可接受的拟合度（CFI=0.905；RMSEA=0.053）。此外，Cronbach's alpha 值证实了所提出结构的内部一致性。此外，还使用竞争模型来选择最佳提出的模型。通过这种方式，评估了不同的模型，假设 BIS 和战斗-逃跑-冻结系统（FFFS）之间的相关强度发生变化。
与五因素人格量表的收敛有效性结果提供了进一步的支持，并与先前的研究结果一致。拥有 RST-PQ 的伊朗语版本对于促进 RST 研究以及展示该理论框架如何有助于解释和预测各种行为（无论是异常还是健康）至关重要。
