Patients with an intellectual disability (ID) and offending histories constitute a challenging clinical group. The present study examined commonalities and differences in demographic, diagnostic and offence characteristics in patients with and without intellectual disabilities who were either convicted for violent or sexual offences and who resided in mandated care in the Netherlands.
We compared 165 offenders with an ID to 249 offenders without an ID. We compared both groups by type of offence (i.e., sexual versus violent offence) using Mann-Whitney U-test or independent samples t-tests for continuous variables and Chi-square tests for categorical variables.
In general, forensic patients with an ID were younger at admission (U=357, z = -12.668, p < .001), had more prior convictions for violent offences (χ(1)= 6.175, p = .013) and more prevalent diagnoses of substance abuse disorders (χ(1)= 9.266, p = .002) than those without an ID. Similar results were found for patients with IDs with sexual offence histories.
A clear understanding of distinct characteristics of forensic patients with intellectual disabilities is crucial in understanding (sexual) violent behavior in this population as it mayassistclinicians in prioritizing interventionstrategies.
有犯罪史的智力障碍（ID）患者是一个具有挑战性的临床群体。本研究考察了在荷兰受强制监护的、有或无智力障碍的、被判犯有暴力或性犯罪的患者在人口统计学、诊断和犯罪特征方面的共同点和差异。
我们将 165 名有智力障碍的罪犯与 249 名无智力障碍的罪犯进行了比较。我们使用 Mann-Whitney U 检验或独立样本 t 检验比较了两组的犯罪类型（即性犯罪与暴力犯罪），对于连续变量使用均数，对于分类变量使用卡方检验。
一般来说，入院时有智力障碍的法医患者年龄较小（U=357，z=-12.668，p<0.001），有更多的暴力犯罪前科（χ(1)=6.175，p=0.013），更普遍存在药物滥用障碍的诊断（χ(1)=9.266，p=0.002）。有性犯罪史的有智力障碍的患者也有类似的结果。
清楚了解有智力障碍的法医患者的独特特征对于理解该人群的（性）暴力行为至关重要，因为这可能有助于临床医生确定干预策略的优先级。
