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.).

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.

  • The test retest reliability of an early version of the NEO after 3 months was: N = .87, E = .91, O = .86.[14]
  • The test retest reliability reported in the manual of the NEO PI-R over 6 years was: N = .83, E = .82, O = .83, A = .63, C = .79.
  • A 2001 study by Kurtz and Parrish[15] on the short-term test-retest reliability yielded coefficients of α = .91–.93 for domains and α =.70–.91 for facets after a one-week interval. ...
  • A 2006 study by Terracciano et al.[16] on the long-term test-retest reliability yielded coefficients of α = .78–.85 for domains and α = .57–.82 for facets after a 10-year interval.
