Appendix Scales derived by principal components analysis (PCA) of WOMBLSQ4. Scales are intuitively named followed by their component questions. Scale means, standard deviations, percentage of variance explained by scale and Cronbach alpha coefficients are given. The final scale about general satisfaction was omitted from PCA with varimax rotation and Kaiser normalisation. Question numbers represent their order on the final questionnaire; negatively worded questions are shown with a minus sign.
