A novel use of genograms in primary care practice is to identify processes and relationships among physicians and staff prior to implementing practice change. The authors hypothesized that the genogram would inform researchers and practice staff, participating in a child maltreatment prevention study, how practice members function in a practice. They describe the use of genograms and show how the genogram results are associated with intervention uptake. Researchers constructed genograms, collected baseline surveys, and conducted postintervention interviews with physicians. Data were analyzed to determine processes associated with intervention uptake. While survey results supported the relationships and conflicts observed in the genograms, the genogram provided more multilevel information that reflected practices' abilities to implement change. By providing a snapshot of the relationship and organizational dynamics within a practice, genograms can assess culture for practice change. Genograms describe organizational dynamics and are useful tools to use prior to initiating new programs.
