A national sample of psychologists were asked whether they had been abused as children and, if so, whether they had ever forgotten some or all of the abuse. Almost a quarter of the sample (23.9%) reported childhood abuse, and of those, approximately 40% reported a period of forgetting some or all of the abuse. The major findings were that (a) both sexual and nonsexual abuse were subject to periods of forgetting; (b) the most frequently reported factor related to recall was being in therapy; (c) approximately one half of those who reported forgetting also reported corroboration of the abuse; and (d) reported forgetting was not related to gender or age of the respondent but was related to severity of the abuse.
