A psychometric evaluation of the Highly Sensitive Person Scale: the components of sensory-processing sensitivity and their relation to the BIS/BAS and "Big Five" reports a study on the Highly Sensitive Person Scale (HSPS) with comparison with NEO-FFI and the BIS/BAS scale.

[edit] Analysis

The researchers conducted a principal component analysis on half of the subjects (380 cases) with the 27 items of the HSPS. Oblimin rotation was used to rotate the results from the PCA (component loadings?). What the parameter of the oblimin rotation was is not stated. A scree plot (written "screen test") was used to determine the number of principal components.

[edit] Critique

  1. The method is not entirely clear: Did they use factor analysis or principal component analysis?
  2. How was the principal component analysis estimated: correlation or covariance?
  3. What parameter in oblimin rotation did they use?
  4. "Scree" is miswritten.
