Despite substantial evidence for the fit of the 3- and 4-factor models of Psychopathy Checklist-based ratings of psychopathy in adult males and adolescents, evidence is less consistent in adolescent females. However, prior studies used samples much smaller than recommended for examining model fit. To address this issue, we conducted a confirmatory factor analysis of 646 adolescent females to test the fit of the 3- and 4-factor models. We also investigated the fit of these models in more homogeneous subsets of the full sample to examine whether fit was invariant across geographical region and setting. Analyses indicated adequate fit for both models in the full sample and was generally acceptable for both models in North American and European subsamples and for participants in less restrictive (probation/detention/clinic) settings. However, in the incarcerated subsample, the 4-factor model achieved acceptable fit on only two of four indices. Although model fit was not invariant across continent or setting, invariance could be achieved in most cases by simply allowing factor loadings on a single Psychopathy Checklist: Youth Version (Forth, Kosson, & Hare, 2003) item to vary across groups. In summary, in contrast to prior studies with small samples, current findings show that both the 3- and 4-factor models fit adequately in a large sample of adolescent females, and the factor loadings are largely similar for North American and European samples and for long-term incarcerated and shorter-term incarcerated/probation/clinic samples.
尽管有大量证据表明基于《心理病理检查表》的成年人和青少年心理变态评定的 3 因素和 4 因素模型很适合，但在青少年女性中证据并不那么一致。然而，之前的研究使用的样本比检查模型拟合度所需的样本小得多。为了解决这个问题，我们对 646 名青少年女性进行了验证性因素分析，以检验 3 因素和 4 因素模型的拟合度。我们还在更同质的样本子集上研究了这些模型，以检查模型在地理区域和设置上是否具有不变性。分析表明，这两个模型在整个样本中的拟合度都很好，在北美和欧洲子样本以及在限制较少的（缓刑/拘留/诊所）环境中的参与者中，这两个模型的拟合度总体上都是可以接受的。然而，在监禁样本中，只有 4 因素模型在四个指标中的两个指标上达到了可接受的拟合度。尽管模型拟合度在大陆或设置上不具有不变性，但在大多数情况下，通过简单地允许《心理病理检查表：青少年版》（Forth、Kosson 和 Hare，2003）上的单个项目的因子负荷在群体之间变化，就可以实现不变性。总之，与之前使用小样本的研究相比，目前的研究结果表明，3 因素和 4 因素模型在一个大的青少年女性样本中都能很好地适应，并且在北美的和欧洲的样本以及长期监禁和短期监禁/缓刑/诊所样本中，因子负荷基本相似。
