Hi Sue,
The following two seem to be what're coming up in the research:
Macksoud's CTWQ includes a version for parents and a version for children.

Mollica’s Harvard Trauma Questionnaire has been previously adapted for this use as well. It is available for purchase. http://hprt-cambridge.org/?page_id=42
Please let me know if neither of these seems to be what you recalled.
