I don't understand this point about it being too bad that 1 is most important. You can just reverse the scale so that 7 is most important. gen scale2 = cond(scale >=1, 8 - scale, 0) That gives you 7 -> 1, 6 -> 2, ..., 1 -> 7, 0 -> 0. Other ways of doing this include -recode-. Whether one-way anova is a good fit is another question. I suspect that few off-the-shelf techniques are quite right here.

The other skills (which they find less important) are not given any score (they are zero in my data).
