A group of researchers is interested in the CCHS, particularly the CCHS 2012 mental health survey. However, they are asking whether they can go a bit further with this data, within the RDC, by linking it to the CCHS 2012 annual component. From the documentation it appears that these are two separate surveys with two different groups of respondents, can you confirm this? If the CCHS 2012 mental health is a subset of the 2012 annual, would they be able to link the two files within the RDC?
They are two different surveys. The CCHS "annual component" is a different set of samples from the "focus content component."You may want to visit our webpage for a brief on the 2012 CCHS-MH: <http://socserv.mcmaster.ca/rdc/surveys.html>
