in the competing scientific network academia.edu you can find the "capability approach" as a separate tag, to which more than 3,400 colleagues have assigned themselves: https://www.academia.edu/People/Capability_Approach. I have not looked for psychiatric topics, but I think there is a chance to find them there (see also the section with more than 500 publications).
I don't know why, but my answer to your request got lost. Therefore another try.
Thanks for your message but I think my work is very different from yours. Anyway, I'll send you an article of mine in which I try to develop an approach for social work based upon the CA.
Despite of this I'm interested in knowing how architectural issues are affected by the CA and its basic ideas of justice. I'm looking forward to hear from you for a better understanding.
By the way, do you know the Human Development and Capability Association and its journal? I'll email you an invitation to contribute any work for an literature index of papers working the approach (in any language)
