摘要

性别估计是生物特征的一个重要组成部分,法医人类学家可根据所分析的骨骼遗骸的完整程度和保存状况,采用多种性别估计方法。人们普遍认为头骨是最具性别二态性的骨骼元素。性别概率诊断法(Diagnose Sexuelle Probabiliste,DSP)采用 10 次测量主骨的方法,于 2005 年推出,并于 2017 年更新为 DSP2。据报道,DSP2 在南美和欧洲人群的研究中具有较高的分类准确率,但该方法尚未在美国样本中进行广泛测试,而且很少有美国从业者将该方法纳入其个案工作中。本研究的目的是使用来自美国的大量现代样本(n = 174)测试 DSP2 的可靠性和准确性。两名观察者收集 DSP2 指标,他们对每个标本的相关人口信息进行盲测。观察者内部和观察者之间的误差分析表明,除 IIMT 外,所有测量结果的一致性均可接受。在使用各种测量组合时,两位观察者的分类准确率都超过了 95%,性别偏差极小;然而,由于更多男性达到了 DSP2 提供性别分类估计所需的 0.95 后验概率阈值,因此出现了包容性性别偏差。鉴于 DSP2 的高准确性,美国的法医人类学家可以考虑将其纳入他们的案例工作中,不过我们建议排除 IIMT 并谨慎使用 SPU。如果达不到后验概率阈值,还需要其他方法。

Sex estimation using metrics of the innominate: A test of the DSP2 method.

Sex estimation is a critical component of the biological profile, and forensic anthropologists may use a variety of sex estimation methods depending upon the degree of completeness and state of preservation of the skeletal remains being analyzed. The innominate is widely accepted to be the most sexually dimorphic skeletal element. The Diagnose Sexuelle Probabiliste (DSP) method, which uses 10 measurements of the innominate, was introduced in 2005 and updated as DSP2 in 2017. While DSP2 has been reported to have high classification accuracy rates in studies of South American and European populations, the method has not been widely tested in US samples, and few US practitioners incorporate this method into their casework. The goal of this study was to test the reliability and accuracy of DSP2 using a large, modern sample from the US (n = 174). Two observers, blinded from demographic information associated with each specimen, collected the DSP2 metrics. Intra- and interobserver error analyses showed acceptable levels of agreement for all measurements, except for IIMT. Classification accuracies exceeded 95%, with minimal sex bias, for both observers and using various measurement combinations; however, an inclusivity sex bias occurred with more males reaching the 0.95 posterior probability threshold required by DSP2 to provide a sex classification estimate. Based on its high accuracy, forensic anthropologists in the US may consider incorporating DSP2 into their casework, although we recommend excluding IIMT and using SPU with caution. Additional methods will continue to be needed when the posterior probability threshold is not reached.
