Aggression can be defined according to impulsive or premeditated features. Impulsivity is defined as an uncontrolled and unplanned form of aggression. On the contrary, premeditation requires planning and is goal-oriented.
The purpose of this study was to validate the basic psychometric properties of the Impulsive/Premeditated Aggression Scale (IPAS) into European Portuguese. The scale evaluates aggression according to impulsive and premeditated features, which are considered the predominant forms of aggressive behavior, and can be used in community, forensic and clinical settings.
Participants from a community sample (n = 957; 424 male) and incarcerated individuals (n = 115, all male) completed the IPAS.
Internal consistency and reliability indicated that the scale has good psychometric properties in both samples. Data from a principal component analysis (PCA) demonstrated similarities to previous structures reported in the literature.
The scale demonstrated to be sensitive to the bimodal classification of aggression in community and forensic samples, indicating its utility in the characterization of aggressive patterns.
攻击行为可根据冲动性或预谋性特征来定义。冲动性被定义为一种不受控制且无计划的攻击形式。相反，预谋性需要计划且以目标为导向。
本研究的目的是验证冲动/预谋攻击量表（IPAS）在欧洲葡萄牙语中的基本心理测量特性。该量表根据冲动性和预谋性特征评估攻击行为，这两种特征被认为是攻击行为的主要形式，可用于社区、法医和临床环境。
来自社区样本（n = 957；424名男性）和被监禁个体（n = 115，均为男性）的参与者完成了IPAS。
内部一致性和信度表明该量表在两个样本中均具有良好的心理测量特性。主成分分析（PCA）的数据显示与文献中先前报道的结构相似。
该量表被证明对社区和法医样本中攻击行为的双峰分类敏感，表明其在攻击模式特征描述中的效用。
