A sample of 450 adult clinical subjects reporting sexual abuse histories were studied regarding their repression of sexual abuse incidents. A iota1 of 267 subjects (59.3%) identified some period in their lives, before age IS, when they had n o memoty of their abuse. Variables most predictive of abuse-related amnesia were greater current psychological symptoms, molesinlion at an early age, errlended abuse, and variables reflecting especiully violent abuse (e.g., victimizalion by multiple perpetrators, having been physicnlly injured as a result of he abuse, victim fears of death ip she or he disclosed the abuse to others). In contrast, abuse characteristics more likely to produce psychological conflict (e.g., etijoyment of the abuse, acceptance of bribes, feelings of guilt or shame) were riot associaled with abuse-related amnesia. The results of [his study are inlerpreted as supporting Freud's inilial "seduction hypothesis, '' as well as more recent theories of post-traumatic dissociation.

As noted by several recent authors (e.g., Lerman, 1986;Masson, 1984;Rush, 1980), Freud posited as early as 1896 that children who had been "seduced" by adults were prone to the development of hysteria in adulthood, especially if the molestation transpired early in life and was subsequently repressed from consciousness (Freud, 1954).Later, of course, Freud reversed his position vis il vis the role of sexual abuse, stating in 1933 that "I was driven to recognize in the end that these reports were untrue and so came to understand that the hysterical symptoms are derived from phantasies and not from real occurrences" (Freud, 1966, p. 584).Despite Freud's ultimate rejection of the role of childhood sexual trauma in the development of later symptomatology, recent research has, in fact, validated much of his early speculation. It is now generally accepted that childhood sexual abuse is quite common in our society (Finkelhor, 1979;Russell, 1983;Wyatt, 1985), and that incidence rates in outpatient clinical populations may parallel those first reported by Freud in his clinical practice (Briere and Runtz, 1987). Such victimization has been associated with a variety of long-term impacts, including depression and anxiety (Courtois, 1979;Elliott and Briere,
