Both theory and empirical research support the application of the psychological flexibility model to understanding aggressive behavior. However, methodological limitations persist, as studies have generally relied upon a single measure of psychological inflexibility, and measures of aggression typically fail to differentiate aggressive behavior based on function. This limits our ability to understand how specific dimensions of psychological (in)flexibility relate to functional differences in aggression. To extend this line of research, the primary aim of this study was to examine the associations between proactive and reactive aggression, and multiple measures of psychological (in)flexibility processes, across three samples: one undergraduate ( = 116) and two online community samples ( = 262 and = 317). Further, we examined the unique contribution of psychological (in)flexibility processes in the prediction of aggression, over and above negative affect-related variables. Proactive and reactive aggression was assessed across all samples, with individual samples also responding to various measures of anger, negative affect, negative urgency, experiential avoidance, cognitive fusion, valued living, or a multidimensional measure of psychological flexibility. Correlational and regression analyses revealed that inflexibility processes were generally associated with reactive aggression, but more inconsistent associations were found with proactive aggression in multivariable models. Flexibility processes, on the other hand, exhibited inconsistent and sometimes unexpected associations with aggression. The psychological flexibility model appears useful in understanding different functions of aggressive behavior, however additional research is necessary to clarify the nature of discrepancies within and between samples.

心理灵活性过程以及攻击性的反应性和主动性功能的多样本研究

理论和实证研究都支持应用心理灵活性模型来理解攻击行为。然而，方法论的局限性仍然存在，因为研究通常依赖于单一的心理僵化测量，而攻击性的测量通常无法根据功能区分攻击性行为。这限制了我们理解心理（不）灵活性的具体维度如何与攻击性功能差异相关的能力。为了扩展这一研究方向，本研究的主要目的是检查主动攻击性和反应性攻击之间的关联，以及心理（不）灵活性过程的多种测量方法，涉及三个样本：一个本科生（= 116）和两个在线社区样本（= 262 和= 317）。此外，我们还研究了心理（不）灵活性过程在攻击性预测中除了负面情绪相关变量之外的独特贡献。对所有样本的主动和反应性攻击进行了评估，个别样本还对愤怒、负面情绪、负面紧迫感、经验性回避、认知融合、有价值的生活或多维心理灵活性测量等各种指标做出反应。相关和回归分析表明，僵化过程通常与反应性攻击相关，但在多变量模型中发现与主动攻击之间的关联更加不一致。另一方面，灵活性过程与攻击性表现出不一致的、有时是意想不到的关联。心理灵活性模型似乎有助于理解攻击行为的不同功能，但是需要进行额外的研究来阐明样本内部和样本之间差异的本质。
