Researchers into the field of traumatic memory recovery note that the longer the period of time a person is asked recall a traumatic event, the less likely they are to remember it. How this works is that surveys that ask about a traumatic event in the last six months get less false negatives than those that ask about a traumatic event in the last twelve months which, itself, gets considerably fewer false negatives than lifetime prevalence.
For men this effect is even more pronounced.
16% of men with documented cases of sexual abuse considered their early childhood experiences sexual abuse, compared with 64% of women with documented cases of sexual abuse. These gender differences may reflect inadequate measurement techniques or an unwillingness on the part of men to disclose this information (Widom and Morris 1997).
Only 16% of men with documented case histories of child sexual abuse disclosed that abuse on a survey intended to capture child sexual abuse. Sixteen percent of men compared to sixty-four percent of women.
That amounts to a disclosure rate of child sexual abuse four times higher in women than in men.
