The deleterious psychological effects of childhood sexual abuse (CSA) have been extensively documented in the research literature. A limitation of this research, however, has been a reliance on overly restrictive and limiting measurements of CSA. Researchers have most commonly referred to discrete instances of rape and molestation; however, evidence suggests that sexual abuse in childhood can include a wide array of acts and that individual survivors can endure many of these.
This study employed latent class analysis to identify homogeneous groups of adult CSA survivors characterized by similar typologies of sexual trauma within a large sample of Danish, treatment-seeking survivors of CSA and incest (N = 454). In total, 18 separate contact and noncontact abuse acts were modeled. Furthermore, the association between abuse-related variables (victim gender, the age at which the abuse started, duration of abuse, and perpetrator of abuse) and the resultant CSA groups, or classes, was estimated.
Four homogeneous CSA groups were identified: an intercourse group, a high-verbal/low-contact group, a high-sexual-contact group, and a sexual-touch group. Some of the groups were distinguishable from others in terms of the frequency of the abuse and the type of perpetrator identified.
The results show that "typologies" of CSA may provide a useful way to describe complex patterns of abuse while also facilitating future investigations of CSA outcome and treatment need. (PsycINFO Database Record
儿童期性虐待（CSA）的有害心理影响在研究文献中得到了广泛的证实。然而，这项研究的一个局限性在于依赖于对 CSA 的过度限制和限制的测量。研究人员最常提到的是强奸和猥亵的离散事件；然而，有证据表明，儿童期的性虐待可以包括一系列行为，而且个体幸存者可能会经历其中的许多行为。
本研究采用潜在类别分析，在一个丹麦 CSA 和乱伦的治疗性幸存者（N=454）的大样本中，确定了以相似的性创伤类型为特征的成年 CSA 幸存者的同质群体。共对 18 种单独的接触和非接触性虐待行为进行建模。此外，还估计了与虐待相关的变量（受害者性别、虐待开始的年龄、虐待持续时间和施虐者）与由此产生的 CSA 群体或类别之间的关系。
确定了四个同质的 CSA 群体：性交组、高言语/低接触组、高性接触组和性触摸组。一些群体在虐待的频率和识别出的施虐者类型方面与其他群体有所区别。
研究结果表明，CSA 的“类型学”可能是一种有用的方法，可以描述复杂的虐待模式，同时也有助于 CSA 结果和治疗需求的未来研究。
