I thought so too. I was quite surprised to get such high Loevinger
coefficients but this might be due to a rather large sample size of 3,300?
Also, does it mean that if they all lie above the critical value of 0.3
that these variables (or traits in this case) form one dimension? I.e. if
two of them were lower than 0.3, the other two would still form such a
dimension?

Many thanks for your advice on this, much appreciated!
