Dear Dr. Schwab:

Attached are two 10-day letters from the staff of the NCHS Questionnaire Design Research Laboratory (QDRL) (Generic clearance OMB 0920-0222). Due to time considerations, we have submitted them together.

The first letter describes plans to conduct research to evaluate a questionnaire on measuring trust in official statistics as part of an international cognitive testing project for the Organization for Economic Co-operation and Development (OECD), Electronic Working Group on “Measuring Trust in Official Statistics”.

The second letter describes how the QDRL plans to conduct a qualitative study designed to investigate Complementary and Alternative Medicine and Well-Being for the National Health Interview Survey (NHIS)

The total number of burden hours for the two projects is 80 hours, 80 participants at 1 hour each.
