* Variables of which we present the mean, the standard deviation and the median are continuous and (approximately) normally distributed; the other variables are categorical.

** Factor scores, normalized resulting from measurement models (with Lisrel) for the (latent) ASE-variables, each loading on three or more additive scales and Homals-dimensions; see references [10,11]. Self-Efficacy is not normalized because this variable consists of one additive scale only, normally distributed.
