Advocacy intervention has been shown to be efficacious at reducing depressive symptoms in women who suffer from intimate partner violence (IPV). However, the intervention effect among abused immigrant women has not been well studied. This study compares the demographic and psychosocial characteristics between abused immigrant and nonimmigrant women, and evaluates the impact of immigration status on the efficacy of an advocacy intervention in reducing depressive symptoms and improving perceived social support. Two hundred abused Chinese women recruited from a local community center in Hong Kong were randomized to receive either the advocacy intervention or usual care. The advocacy intervention was found to be effective at reducing depressive symptoms and improving social support for abused Chinese nonimmigrant women, but the same effects were not seen for abused immigrant women. The findings provide essential insights into the need for developing targeted and efficacious advocacy interventions for abused immigrant women. Effective services to address abused immigrant women's needs were also suggested.
