Mike,

More context is necessary - but not for the purpose of meaning: that's clear.

Rather, if it appears once, in the abstract, the above would be perfectly acceptable.
If it appears umpteen times you might need something more concise.

Hi,

Just realised that your question refers to the positive, not the negative.

As I understand it, you are asking about 'contributoriedad', which surely means the 'degree to which XX is contributory' (which may have degrees such as contributory, special-rate contributory, non-contributory.
I'm sure there's no single word for that in English - it suppose it would be 'contributableness' (and I wonder if the Spanish word hasn't been invented ...).
If its a (sub)title, I would put 'Contributory/Non-contributory? knowing that the exaplanations are coming soon after.
