Validity and Reliability
Based on the most recent forms of MBTI (M and Q), the internal consistency was .90 for Form M and .77 for Form Q. A sample of 3,009 people representing a national sample was used for Form M, whereas a nationally representative sample of 1,378 was used for Form Q. The test is given to 2 million people every year; in addition, the test is used by companies and researchers. The MBTI is an established instrument used for the analysis of personality.
