Research has indicated that life‐course persistent offenders typically vary their offending style, following a criminal career progression from co‐ to solo‐offending. Few studies have investigated the offenders who contemporaneously mix their style of offending. A sample of 1,047 male adolescent offenders from the Pathways to Desistance study was investigated over a 7‐year period. Participants were identified as solo, co or contemporaneous mixed style (CMS) offenders for each wave of data and one‐way between groups analysis of variance was conducted to examine variations between the different offending styles in terms of offending frequencies, exposure to violence, peer antisocial behaviour and influence, resistance to peer influence, impulse control and psychopathy. CMS offenders were found to consistently report significantly higher rates of offending and present significantly higher negative risk factors and lower protective risk factors than solo‐ and co‐offenders for the duration of the study. A multinomial logistic regression was used to investigate predictors of offending style with CMS as the reference category. Higher levels of exposure to violence and peer antisocial behaviour and lower levels of impulse control predicted membership of the CMS group for the first part of the study when compared with co‐offenders; and higher levels of exposure to violence and peer antisocial behaviour continued to predict CMS offending when compared to solo‐offenders until the end of the study.

青春期男性样本中犯罪风格与心理和社会危险因素的关系

研究表明，随着犯罪职业从共同犯罪发展到个人犯罪，终身终身犯罪者通常会改变犯罪风格。很少有研究调查那些同时混合了自己犯罪风格的犯罪者。在长达7年的时间里，对“通往疾病之路”研究的1,047名男性青少年犯罪者进行了抽样调查。每一波数据被确定为参与者是单人，同时或同时代混合风格（CMS）犯罪者，并且进行了群体间单因素方差分析以检查不同犯罪类型之间在犯罪频率，暴露于暴力，同伴方面的差异。反社会行为和影响，抵抗同伴影响，冲动控制和精神病。在研究期间，发现CMS违规者的违法率始终较高，并且负风险因子和保护性风险因子均显着高于独犯和共同犯。使用多项逻辑回归分析，以CMS作为参考类别调查违规风格的预测因素。与同罪犯相比，本研究第一部分中较高的暴露于暴力和同伴反社会行为的水平，以及较低的冲动控制水平可以预测CMS组的成员身份；直到研究结束时，与单独犯罪者相比，暴力行为和同伴反社会行为的较高暴露水平继续预测着CMS犯罪。
