The MBTI measures an abbreviated set of personality facets that are better assessed by such instruments as the FFI or NEO-PI. It also doesn't take into account Openness to Experience which in my mind is as important as Extraversion or Neuroticism.
The FFI is shorter than the Meyers-Briggs, but was developed using more modern test development methods. Moreover it has much better validity and reliability. The NEO-PI has over 200 items, and provides a content space that adequately samples the 5 basic facets of personality. In some research I did as part of a grad course on test development, we related the NEO-PI and the Meyers Briggs using a sample of 3600 business admins and marketing people in four different large companies. The Meyers-Briggs model was not adequate to explain the data (ie., the goodness-of-fit measures were not statistically significant), while the full Five Factor Model provided a very good fit to the data. When I ran a confirmatory factor analysis on the data, again the NEO-PI adequately mapped to the underlying factors within the data. In contrast only the E and N scales in the MBTI were defined adequately, the remaining MBTI subscales split across all five underlying factors in the data set. My own conclusion with these results is that why use a measure that doesn't adquately represent what's within the population? I I was still doing that sort of stuff, I'd trash the MBTI and start using the FFI or the NEO-PI. pardon the experimental psychologist speak. larry On Mon, 8 Nov 2004 10:27:02 -0600, Gruss Gott <[EMAIL PROTECTED]> wrote: > > Jerry Johnson <[EMAIL PROTECTED]> wrote: > > she stood up, exclaimed "I don't think I belong in this group", > > and ran for the instructors.
