They studied whites, blacks and Latinos taking into consideration neighborhood, mental health status and family structure. The study showed that black families suffering from maternal depression had little effect on child behavior. It has been hypothesized that in a black family the extended family works together because their culture is to take care of each other. In the other two categories, maternal depression had a large effect on child behavior. When they addressed the neighborhood, significant effects on children's behavior were found in black and white neighborhoods, but in Latino communities, neighborhood did not appear to influence children's behaviors. It has been hypothesized that Latinos have a strong sense of loyalty and that parents have a high degree of parental involvement, which may include limiting the child's interactions with their peers. Although differences were recognized, all groups showed similar outcomes in terms of health, income status, available resources, and limited funding for education.(Pachter
