JS, you're on the right track there. There are innumerable cases where kids lied about abuse because of the way they were questioned by therapists with a hidden agenda. Essentially, what happens is the therapist subjects the kid to an interrogation until the kid gives in and tells her (in nearly all such cases the therapist is female) what she wants to hear. It happened with a lot of adults as well before the "recovered memories" scam was debunked. The problem is that the whole area of child abuse has taken on the characteristics of a witch-hunt, to the point where a kid who alleges abuse is not only instantly believed but is rewarded with boatloads of attention while those who say "nothing happened" are subjected to endless sessions of psychobabble. Hardly surprising the choice most of them end up making.
