We applied offending trajectory analyses to 387 men adjudicated for child sexual exploitation material (CSEM) offenses. After an average of 20 years, we found two trajectories of sexual offending and violent offending: one that peaked in late adolescence and was associated with higher rates of crimes, and one that peaked in the 30s and was associated with a lower rate of crime. We found four trajectories when modeling any crime. The findings highlight the heterogeneity of men with CSEM offenses. Although lifelong patterns of numerous sexual crimes were uncommon, men with more sexual crimes had greater indicators of sexual interest in children and a younger age of first contact with police. CSEM offenses were rarely the first offense in their criminal trajectories. As such, early intervention targeting youth before they are further advanced in their criminal careers may also reduce future CSEM offending.

我们对 387 名因儿童性剥削材料 (CSEM) 犯罪而被裁定的男性进行了犯罪轨迹分析。平均 20 年后，我们发现了性犯罪和暴力犯罪的两种轨迹：一种在青春期后期达到顶峰，与较高的犯罪率有关，另一种在 30 年代达到顶峰，与较低的犯罪率有关。在对任何犯罪进行建模时，我们发现了四个轨迹。调查结果突出了 CSEM 犯罪男性的异质性。尽管终生多次性犯罪的模式并不常见，但性犯罪较多的男性对儿童的性兴趣指标更高，首次与警察接触的年龄更小。CSEM 罪行很少是其犯罪轨迹中的第一次犯罪。像这样，
