Migrant farmworker communities present distinct challenges that require new
approaches for community participation in research. In the State of Oregon
an agency that advocates for the migrant farmworker community has collabor
ated successfully with university researchers to implement a research progr
am directed to reducing pesticide exposures among the children of migrant f
armworkers. The research process has included both qualitative research met
hods with members of the community and quantitative approaches to measure p
esticide dust residues in homes. biomarkers of pesticide exposure, and effe
cts on health. A committee of university and community stakeholders advises
the research. Evaluative processes have been initiated to assess the effec
tiveness of the participatory model used in this project. The components of
the preliminary process evaluation and results are presented. Evaluative d
ata show that researchers and community members differ on perceptions of co
mmunity involvement and the extent to which communication problems have bee
n resolved between the two groups. Suggestions for improved community invol
vement and communication are given.
