Research Focus

Dr. Fettes’ research focuses on the emotional and behavioral health of underprivileged populations of children and youth. She has published several studies comparing child-welfare involved populations of youth (using NSCAW data) with community samples of youth (using AddHealth data) on substance use. Currently, Dr. Fettes collaborates on two federally funded research studies which examine a system-wide implementation of an evidence-based, in-home parenting intervention designed to reduce child neglect and prevent recidivism. These longitudinal, mixed-methods studies focus on identifying and improving system, organizational, and individual factors surrounding the implementation of evidence-based practices into public sector settings. In addition, expansions of the implementation are focused specifically and uniquely on addressing issues of domestic violence among Latino families with histories of child welfare involvement.
