The current study investigated whether a multidimensional model could underlie impulsivity and its associations with various disorders in a forensic sample. Data were available from self-report and behavioral impulsivity instruments of 87 forensic patients. Principal component analysis (PCA) was used to derive a dimensional impulsivity model, and the relationship between and possible predictive validity of impulsivity dimensions for psychopathology was investigated using product moment correlations and regression analysis. A 3-dimensional model of impulsivity was derived, with factors labeled impulsive decision making, sensation seeking, and response inhibition. Impulsive decision making was a predictor for a history of drug dependence, the impulsive lifestyle facet of psychopathy, and antisocial personality disorder. Sensation seeking was not related to any psychopathology. Inadequate response inhibition was a predictor for drug dependence, psychopathy, and antisocial personality disorder. Given the importance of the concept of impulsivity with regard to forensic risk assessment, the current results replicated earlier impulsivity models and imply that impulsivity is a crucial target for diagnosis and interventions and underlines the importance to consider impulsivity as a multidimensional construct.

法医患者冲动建模：冲动的三维模型。

当前的研究调查了多维模型是否可以作为冲动的基础以及其与法医样本中各种疾病的关系。数据可从87名法医患者的自我报告和行为冲动工具获得。使用主成分分析（PCA）来推导维数冲动模型，并使用乘积矩相关性和回归分析研究了冲动维数对心理病理学之间的关系以及可能的预测有效性。推导了一个3维冲动模型，其中的因素标记为冲动决策，感觉寻求和反应抑制。冲动的决策是药物依赖史，精神病的冲动生活方式和反社会人格障碍的预测指标。寻求感觉与任何精神病理学无关。反应抑制不足是药物依赖性，精神病和反社会人格障碍的预测因素。考虑到冲动性概念对于法医风险评估的重要性，当前结果重复了较早的冲动性模型，暗示冲动性是诊断和干预的关键目标，并强调了将冲动性视为多维结构的重要性。
