The major research question in this report is the extent to which family membership disability affects the magnitude of internal family interaction. Other research foci addressed here are: the relationship that exists between parental-nonparental or husband-wife positional locations of disabled family members and the magnitude of internal family interaction; and the influence that community type (rural-urban) or family type (nuclear-extended or complete-incomplete) has. Data for this study came from interviews with 553 black homemakers conducted during the summers of 1970 and 1971 in a large metropolitan center, a small town, and two small open-country villages in East Texas. Four major abstract conclusions are drawn: disabled families generally experience lower levels of internal family interaction than nondisabled families; there are no universal relationships between the degree of family membership disability and the degree of internal family interaction; neither community nor family type significantly influences the impact of the incidence of family membership disability; and certain community and family types influence certain relationships between the degree of family membership disability and the degree of internal family interaction.
