Dr. Larrison is interested in community based service agencies and how they interact with clients and policies to create outcomes for clients. Employing primary data, he has studied community based mental health services in the U.S., community development in rural Mexico, and the impact of welfare reform in Georgia. His use of field research techniques has led to extensive experience in training and supervising research staff, collecting and analyzing primary data, and using mixed methods. He has concentrated on two sets of factors related to community based service outcomes: 1) Client-level factors with a particular consideration to socioeconomic status, gender, level of health, and race, culture and ethnicity; and 2) agency-level factors with a particular consideration to program model, level of innovation, and organizational climate. Several of Dr. Larrison’s peer reviewed articles have been placed on suggested reading lists by the U.S. Department of Housing and Urban Development, the U.S. Government Accounting Office, and The World Bank.
