I am wanting to get estimates of the test-retest correlation for the six HEXACO domains. I'm curious to obtain estimates of test-retest correlation over various time frames (e.g., 1 month, 1 years, 2 years, etc.).

**Tags:** measurement, personality, correlation

I have not yet found HEXACO domain estimates. I've had a lock through the main articles listed as references on <http://hexaco.org/references> but they seem to focus more on internal structure.

However, the HEXACO-PI is quite similar to the the NEO-PI in terms of number of items per domain and the general approach to trait measurement. Thus, I would expect that NEO-PI stability would provide a ballpark of what to expect. The following is a summary of few studies from the Wikipedia article on the NEO-PI.
