Item factor analysis of the Italian version of the Myers-Briggs type indicator

The 95 scored items of the Italian version of the Myers-Briggs Type Indicator (MBTI) Form F were subjected to a rotated, simple-structure factor analysis with a sample of 1798 subjects. Five factors were obtained of which four resembled the four MBTI scales. Cronbach α-coefficients are reported for the scales and factors together with their intercorrelations. The results support the scale structure of the MBTI, even if some items could be deleted. Suggestions are made for future research.
