Abstract : The report reviews previous research on instructions used to administer personality measures. The main finding is that most of this research has been focused on what can be manipulated by instructions, not on what it is in the instructions that does the manipulation. The report also reviews attempts to deal with the problem of the simplex (or Guttman scale) as it affects the factor analysis of personality measures. The principal finding is that there is presently no completely satisfactory method for taking the simplex into account in a multi-dimensional factor analysis. The report develops a method, and corresponding rationale, for the comparison of factor analytic results obtained under different instructions. The method can be applied, whether or not the simplex is taken into account in the factor analyses. (Author)
