  1. See additional file 1 for item descriptions. Items 3h, 4a, 4b, 4f, 4h and 4j have been reverse coded. Items 4c and 4e were deleted. The first 7 columns give the frequencies of each of the 7 response categories (after reverse-coding, as appropriate). Column 10 gives the number (out of 261 subjects with responses to at least 1 DASS item) of subjects with a missing response to the item in question.
