Abstract

Recent findings have highlighted unique risk factors for female-perpetrated violence as well as limitations in its risk assessment. To address these shortcomings, the Female Additional Manual (FAM) was designed as a complementary tool for the gender-neutral framework of the Historical, Clinical, Risk Management-20 (HCR-20). Little research has been undertaken exploring the predictive validity of the FAM, particularly when used with the most recent version of the HCR-20 (HCR-20v3), leaving equivocal evidence in regards of its use in clinical practice. The present study compared the predictive validity of the HCR-20v3 with and without the FAM for inpatient violence. The sample consisted of 42 female forensic psychiatric patients in a low to medium secure unit in the UK. Results revealed a significant difference in the predictive validity of the HCR-20v3 compared to the FAM when assessing for physical violence and no significant differences between the instruments’ validity in predicting nonphysical and any violence. In line with existing literature, the HCR-20v3 was an overall good predictor of violence. While the FAM was less accurate than the HCR-20v3 at predicting physical violence, it achieved moderate to large effect size in predicting each category of violence. The findings provide a degree of support for using the HCR-20v3 when assessing the risk of violence in women but do not demonstrate improved predictive power when adding the FAM.

摘要

最近的研究结果强调了女性实施暴力的独特风险因素及其风险评估的局限性。为了解决这些缺点，女性附加手册 (FAM) 被设计为历史、临床、风险管理 20 (HCR-20) 性别中立框架的补充工具。很少有研究探索 FAM 的预测有效性，特别是与最新版本的 HCR-20 (HCR-20v3) 一起使用时，其在临床实践中的使用留下了模棱两可的证据。本研究比较了使用和不使用 FAM 的 HCR-20v3 对住院暴力的预测有效性。样本由 42 名女性法医精神病患者组成，他们居住在英国的一个低至中安全单位。结果显示，在评估身体暴力时，HCR-20v3 与 FAM 的预测有效性存在显着差异，而这些工具在预测非身体暴力和任何暴力方面的有效性没有显着差异。与现有文献一致，HCR-20v3 总体上是暴力的良好预测因子。虽然 FAM 在预测身体暴力方面不如 HCR-20v3 准确，但它在预测每种暴力类别方面实现了中等到大的效应大小。研究结果为评估女性暴力风险时使用 HCR-20v3 提供了一定程度的支持，但并未证明添加 FAM 后预测能力有所提高。与现有文献一致，HCR-20v3 总体上是暴力的良好预测因子。虽然 FAM 在预测身体暴力方面不如 HCR-20v3 准确，但它在预测每种暴力类别方面实现了中等到大的效应大小。研究结果为评估女性暴力风险时使用 HCR-20v3 提供了一定程度的支持，但并未证明添加 FAM 后预测能力有所提高。与现有文献一致，HCR-20v3 总体上是暴力的良好预测因子。虽然 FAM 在预测身体暴力方面不如 HCR-20v3 准确，但它在预测每种暴力类别方面实现了中等到大的效应大小。研究结果为评估女性暴力风险时使用 HCR-20v3 提供了一定程度的支持，但并未证明添加 FAM 后预测能力有所提高。
