In order to study the differences between severe intimate partner violence (S-IPV) and less severe intimate partner violence (LS-IPV), reports by 16,385 women who had suffered some type of abuse in 2016 and 2017 were analysed by means of the Police Risk Assessment Questionnaire. Chi-square tests indicate that S-IPV aggressors present criminological features to a significantly greater extent and are more likely to perpetrate various types of violence against their partners (for example, sexual aggression, death threats, degrading treatment, and controlling behaviour). Their behaviours seem to depend more on their beliefs and attitudes than on any possible psychopathological disturbance. Likewise, the victims of S-IPV are significantly more likely to report substance abuse, isolation from their environment, and vulnerability due to a mental disorder or disability; furthermore, they are less likely to report their abusers and continue with the judicial process. Therefore, efforts must be focused on fighting isolation, guaranteeing access to assistance and support services, and protecting victims during the processing of the criminal investigation. Professionals must also be alert to conflicts between partners linked to emotional breakdown and apply the relevant risk-management strategies, especially in cases with a history of mistreatment of women and an increase in violence severity.

为了研究严重亲密伴侣暴力 (S-IPV) 和不太严重的亲密伴侣暴力 (LS-IPV) 之间的差异，警方分析了 2016 年和 2017 年遭受某种类型虐待的 16,385 名妇女的报告风险评估问卷。卡方检验表明，S-IPV 攻击者在更大程度上表现出犯罪学特征，并且更有可能对其伴侣实施各种类型的暴力（例如，性侵犯、死亡威胁、有辱人格的待遇和控制行为）。他们的行为似乎更多地取决于他们的信念和态度，而不是任何可能的精神病理学障碍。同样，S-IPV 的受害者更有可能报告滥用药物、与环境隔离、由于精神障碍或残疾而导致的脆弱性；此外，他们不太可能举报施虐者并继续进行司法程序。因此，在刑事调查过程中，必须重点打击孤立、保障获得援助和支持服务以及保护受害者。专业人员还必须警惕与情绪崩溃有关的伴侣之间的冲突，并应用相关的风险管理策略，尤其是在有虐待妇女历史和暴力严重程度增加的情况下。在刑事侦查过程中保护被害人。专业人员还必须警惕与情绪崩溃相关的伴侣之间的冲突，并应用相关的风险管理策略，尤其是在有虐待妇女历史和暴力严重程度增加的情况下。在刑事侦查过程中保护被害人。专业人员还必须警惕与情绪崩溃有关的伴侣之间的冲突，并应用相关的风险管理策略，尤其是在有虐待妇女历史和暴力严重程度增加的情况下。
