I find these sources lacking in credibility, given that the first two seem to be part of the "Recovered Memory of Sexual Abuse" and ritual satanic abuse school, that caused so many children to unjustifiably be removed from their families on the flimsiest of evidence. Most of the children were subsequently returned to their families as this theory was discredited. The theory had been that the abused had suppressed memories of their abuse, but that specialist psychologists could reach into their subconscious and expose it.

The last two link starts by stating " it is known that..." and "it is believed that........." quoting statistics without any source.
