The Danbury-based Connecticut Institute for Communities has been awarded a federal grant to improve access to mental health services.  The organization will use the $500,000 to begin the planning and development of a new psychiatric residency program.  Plans calls for 16 psychiatry residents at a time, phasing in four residents per year in a four-year program.  The grant is from the federal Health Resources & Services Administration.  The Teaching Health Center at CIFC, where the residency program will be housed, already has an Internal Medicine residency program.  CIFC officials say Health Care Professional Shortage Area scores of where health professionals are needed most, with 1 being the lowest need and 25 the highest, Danbury is at 23.  That's one of the highest scores in the state.
