There is a recognised relationship between psychopathy and instrumental violence, but not all violence by people who meet the criteria for psychopathy is instrumental.
Our aims were to compare offence types among forensic psychiatric patients with and without the Psychopathy Checklist: Screening Version (PCL: SV) criteria for psychopathy. Our specific questions were whether factor 1 - the interpersonal affective dimension - was related to instrumentality and on severity of the violent crime. Our hypothesis was that the relationship between psychopathy and instrumental violence would be dependent on the severity of the violent crime.
Sixty-five male patients at the forensic psychiatric hospital in Sundsvall, all with a violent criminal history, were assessed for psychopathy through interview and records using the PCL: SV. Severity and the instrumentality of their previous violence were coded using the Cornell coding guide for violent incidents.
The interpersonal features of psychopathy (the interpersonal facet), and only the interpersonal features were significantly associated with instrumentality and severity of violence. Instrumentality was also significantly related to the severity of the violence, independent of psychopathy score.
The results indicated that, at least among forensic psychiatric patients, planning is more likely than not with respect to serious crimes. The specific link between interpersonal features of psychopathy and instrumental and severe violence suggests potential clinical value in recognising subtypes of psychopathy.
精神病态与工具性暴力之间存在公认的关联，但并非所有符合精神病态标准的人实施的暴力都是工具性的。
我们的目的是比较有和没有精神病态筛查版（PCL:SV）标准的法医精神病患者的犯罪类型。我们的具体问题是，因素1——人际情感维度——是否与工具性及暴力犯罪的严重程度有关。我们的假设是，精神病态与工具性暴力之间的关系将取决于暴力犯罪的严重程度。
Sundsvall法医精神病医院的65名男性患者，均有暴力犯罪史，通过使用PCL:SV进行访谈和查阅记录来评估其精神病态情况。使用康奈尔暴力事件编码指南对他们之前暴力行为的严重程度和工具性进行编码。
精神病态的人际特征（人际方面），且只有人际特征与暴力的工具性和严重程度显著相关。工具性也与暴力的严重程度显著相关，与精神病态得分无关。
结果表明，至少在法医精神病患者中，严重犯罪很可能是有预谋的。精神病态的人际特征与工具性及严重暴力之间的具体联系表明，识别精神病态亚型具有潜在的临床价值。
