Gray’s Reinforcement Sensitivity Theory is a neurobiological model developed to explain the regulation of behavior and emotions, using the BIS and BAS systems as motivational constructs based on variables of sensitivity to reinforcement, associated with the emergence of internalizing and externalizing psychopathologies. The objective was to analyze the factor structure, and invariance of the BIS–BAS IPIP-R translated into the Spanish language. A non-probabilistic sampling of 288 people between the ages of 18 and 45 from the city of Bogotá, Colombia (167 women and 121 men, average age of 28.92 ( SD = 7.53) was carried out. Among the results, a two-dimensional structure was verified with correlated factors and residual covariances, once included when reviewing the modification rates and the favorable adjustment of the model. In the invariance analysis of the correlated two-dimensional model, when imposing progressive and sequential restrictions, differential values are presented, indicating that the factor loads are invariant in nested groups. In conclusion, evidence of the two correlated dimensions that support Gray’s theory of activation and inhibition systems independent of sex and age was obtained.

BIS-BAS 量表的因子结构和不变性分析，IPIP-R 版本

格雷的强化敏感性理论是一种神经生物学模型，用于解释行为和情绪的调节，使用 BIS 和 BAS 系统作为基于对强化敏感性变量的动机结构，与内化和外化精神病理学的出现相关。目的是分析翻译成西班牙语的 BIS-BAS IPIP-R 的因子结构和不变性。对哥伦比亚波哥大市 18 至 45 岁的 288 人（167 名女性和 121 名男性，平均年龄为 28.92 岁（SD = 7.53））进行了非概率抽样。结构用相关因素和残差协方差进行验证，一旦在审查修改率和模型的有利调整时包括在内。在相关二维模型的不变性分析中，当施加渐进和顺序限制时，呈现差异值，表明因子载荷在嵌套组中是不变的。总之，获得了支持格雷的独立于性别和年龄的激活和抑制系统理论的两个相关维度的证据。
