Factor analysis and rotation of the 566 MMPI items

Because of the still imperfectly understood basic factor structure of the MMPI, a principal components analysis and varimax rotation was conducted on the MMPI item responses of 50 female under-graduate students of education at Massey University. Eight factors were extracted: neuroticism, antisocial behavior, fundamentalist religiosity, subjectivity, introversion, paranoic tendency, depression, and physical symptoms. The possibly different factor structure for males and females needs explication in further work.
