This is only half related, but half is a pretty good start. The Myer-Briggs Type Indicator (MBTI) lists the personality type INFP as one of the smallest of the general population with a disproportionate representation of great writers. (http://www.personalitypage.com/INFP_car.html goes so far as to state "It's worth mentioning that nearly all of the truly great writers in the world have been INFPs.") Similarly, an informal poll (http://www.mcmanweb.com/article235.htm) found that the introverted and idealist personality types (INF)are most likely to report being diagnosed with depression. I personally believe that both are linked to personality type, being a oft-depressed INFP writer-type i fit the mold fairly well.
