The acculturation gap-distress model purports that immigrant children acculturate to their new culture at a quicker pace than their parents, leading to family conflict and youth maladjustment. This article reviews literature on the acculturation gap-distress model, showing that acculturation gaps function in unique ways depending on many social and contextual variables. In contrast to the original model, which only discusses 1 type of acculturation gap, there are at least 4 types of acculturation gaps: (1) the child is "more" acculturated than the parent in the "host" culture, (2) the child is "less" acculturated than the parent in the "host" culture, (3) the child is "more" acculturated than the parent in the "native" culture, and (4) the child is "less" acculturated than the parent in the "native" culture. A review of research indicates that each of these types of gaps function in unique ways. (Contains 1 figure and 3 tables.)
