Research Summary

As a clinical child and school psychologist, I am broadly interested in ways the principles of developmental psychopathology can be used to explore the impact of substance abuse on family process, parent-child relationships, and the psychosocial development of children. Recent work has been focusing on male gender and substance abuse. Three ongoing projects are focusing on the psychosocial adjustment of substance-abusing men as fathers. In the first, a comparative research design and development-ecological perspective on parenting is being used to document ways the fathering of opioid-dependent men differs from that of men with no history of drug or alcohol dependence. In the second, qualitative research methods and life-history narratives are being used to construct a grounded theory that will outline the process by which developmental, psychological, situational, and systemic influences interact, for better or worse, to affect the fathering of substance-abusing men. In the third, motivational and interpersonal techniques are being integrated in the development of an individual, gender-specific, relational psychotherapy for methadone-maintained men interested in being more effective fathers.

Secondary areas of interest include 1) the assessment, treatment, and prevention of adolescent substance abuse; and 2) male gender role development.
