The aim of this research is to perform a psychometric analysis of the reduced version of the Personality Assessment Inventory (PAI-R) in the Spanish prison population. The sample consists of 294 inmates (265 men and 29 women) who are serving prison sentences in the Penitentiary Centers of the Autonomous Community of Galicia. The average age is 41.20 years (SD = 10.51). The internal consistency of the scale showed a high value in the global scale (α = .951), with the clinical scales showing the best reliability. The confirmatory analysis showed a good fit of the model, both in the clinical scales (X2[43] = 283.108; RMSEA = .065; CFI = .892; GFI = .899; AGFI = .927; p < .01) and in those that include interpersonal problems and requests for help (X2[13] = 44.205; RMSEA = .061; CFI = .913; GFI = .959; AGFI = .912; p < .01). With these results it can be said that the abbreviated version of the PAI is a valid and effective instrument for the estimation of personality characteristics in forensic environments.

这项研究的目的是对西班牙监狱中的人格评估表（PAI-R）的简化版进行心理分析。样本包括294名囚犯（265名男性和29名女性），他们在加利西亚自治社区的监狱中服刑。平均年龄为41.20岁（SD  = 10.51）。量表的内部一致性在全局量表中显示出很高的价值（α= .951），其中临床量表显示出最佳的可靠性。验证性分析显示，该模型在临床量表上均很好拟合（X2 [43] = 283.108； RMSEA = .065； CFI = .892； GFI = .899； AGFI = .927；p <0.01），以及那些包含人际问题和寻求帮助的人（X2 [13] = 44.205； RMSEA = .061； CFI = .913； GFI = .959； AGFI = .912；p  <.01）。有了这些结果，可以说，PAI的缩写版是评估法医环境中人格特征的有效手段。
