(A handful of sources to start with: paper on disabled people in Germany that shows happiness recovers after disability, paper on Spanish people with intellectual disabilities shows they are largely satisfied with their lives, the average life satisfaction of people with disabilities in Northern Ireland is 7⁄10, across EU member states it’s between 6.2 and 7 out of ten.)

This seems like a reiteration of Geoffrey Miller’s comment, so all the discussion there applies.
