Predictors of grandmother participation in a multigenerational study

Results of a growing body of literature regarding multigenerational relationships indicate that grandparents directly and indirectly influence their grandchildren's development. However, multiple generations have been difficult to assemble for research purposes, with refusal rates ranging from 40 percent to over 80 percent. Despite difficulties in obtaining information from more than one generation of family members, data examining potential biases in the selection of participants have rarely been reported. The present study explored predictors of grandmother participation in a multigenerational study with 84 mothers, 84 infants, and 52 maternal grandmothers. Results indicated that grandmothers were less likely to participate in the study when grandchildren experienced preterm birth and when mothers reported less family of origin support. However, grandmothers who participated in the study reported high levels of intergenerational involvement and contact with daughters and grandchildren.
