and unconfident self-evaluations when confronted with ICT-related troubles. Note, given how the items were coded, the Negative self-concept factor has the same polarity as the Positive self-concept factor, that is, a high value in the Negative self-concept factor means that the self-concept is little negative.
The factor Social exposure to ICT (Factor 3) was empirically defined by 12 items representing mostly the wish to share and communi-cate ICT-related experiences and knowledge with others. The remaining two factors were interpreted as factors of ICT interest. The factor Interest in computers (Factor 4) represented a personal orientation toward computers (which explicitly means
desktop computers), whereas the items of the second factor Interest in mobile devices (Factor 5) mainly focused on mobile devices, such as smartphones or tablet computers.
The following picture emerged when inspecting the correlations among the five explored latent factors (see Table 2): Except for two non-significant correlations between the factors Interest in computers and Negative self-concept related to the use of ICT (r 6 .03) as
