This study aimed to analyze the fit of the four-factor model of the 29-item and 12-item Buss-Perry Aggression Questionnaire (BPAQ) on a sample of Portuguese male perpetrators of intimate partner violence (IPV; N = 279) and to test the measurement invariance between sample type (forensic and non-forensic) and sentence type (prison and community). Confirmatory factor analysis (CFA) did not support the four-factor model of the BPAQ 29-item version. The four-factor model of the BPAQ–short form (BPAQ-SF) showed a good fit. Sufferable values for internal consistency and good values for convergent and discriminant validity were found. Cross-sentence measurement invariance using the present sample and cross-sample measurement invariance of the BPAQ-SF using a previously collected sample of students was established. Overall, our results support BPAQ-SF as a valuable brief and psychometrically reliable measure of aggression for use with both individuals from the community and IPV perpetrators with different sentences.

本研究旨在分析 29 项和 12 项巴斯-佩里攻击问卷 (BPAQ) 的四因素模型对葡萄牙男性亲密伴侣暴力 (IPV; N= 279）并测试样本类型（法医和非法医）和句子类型（监狱和社区）之间的测量不变性。验证性因子分析 (CFA) 不支持 BPAQ 29 项版本的四因子模型。BPAQ-短形式 (BPAQ-SF) 的四因子模型显示出良好的拟合。发现了内部一致性的可承受值以及收敛和区分效度的良好值。建立了使用当前样本的交叉句子测量不变性和使用先前收集的学生样本的 BPAQ-SF 的交叉样本测量不变性。总体而言，我们的结果支持 BPAQ-SF 作为一种有价值的简短且心理测量学上可靠的攻击性度量，可用于来自社区的个人和具有不同句子的 IPV 肇事者。
