[Endogenous and neurotic depression again, II: is the separation of the two a methodologic artifact?].

: The authors study the Kiloh and Garside's (1963) and Carney's et al. (1965) data. They apply a Factorial Analysis without and with Varimax rotation. Only account a bipolar factor (endogenous/neurotic) the unrotated solutions, but not in rotated solutions. They discuss the validity of the classification endogenous/neurotic depression supported by a erroneus application of the Factorial Analysis method.
