imageThe MBTI assessment has been revised several times since it first appeared in 1942. New item formats and scoring methods were developed and tested first by Isabel Myers and later by professional psychometricians, with each revision leading to technical improvements over the previous form. The most recent forms are Form M and Form Q, both of which use item response theory (IRT)-based scoring and item selection.

Form M, first published in 1998, is the standard form for identifying an individual’s four-letter type. Based on results from a broad, nationally representative sample of 3,009 people, each of the four preference scales has internal consistency reliability of .90 or greater.

Form Q, first published in 2001, identifies an individual’s four-letter type and produces a more detailed representation of individual differences within type by reporting 20 facets. Based on results from a nationally representative sample of 1,378 people, median internal consistency of the 20 facets is .77.
