What happened to the questionnaires?

In a recent post, Perry mentioned a "vague memory" of filling out a "long" and "very detailed" questionnaire. I also remember filling out a long and detailed questionnaire at the 1987 SATTC in Peru. It included questions about drug use and sexual activity. My roommates (including one who somehow got measles and was quarantined in a room with an intercom and speakers) and I discussed some of our answers and I remember being shocked to find out that one of them had smoked a cigarette in the last 3 months. In response to some of the questions, I disclosed my first sexual experiences at age 7 (with two boys aged 12 and 13) and age 11 (with a 29-year-old woman). My responses also detailed years as both a victim of and witness to incidents of domestic violence. A few years later I found similar questionnaires that my parents had filled out in the late 1970s. I remember my mother's answer to the question of whether she wanted to have sex with Mo was that she had no desire to but that if she met him she probably would. I also recall TF claiming that they first learned about the prevalence of adult-child sex and child abuse in TF by reading the questionnaires completed by the participants in the Mexico and Peru TTCs.

Anyways, I was wondering if anyone knows what happened to these questionnaires. Who read them? Are they still stored somewhere? Is it reasonable to believe TF when they claim that the results of the questionnaires provided the first inkling they had of the widespread sexual and physical abuse of children in TF and that in response they adopted apropriate policies banning certain types of abuse?
