A study was made of the ways in which norms of distributive justice constructed within families depend on types of family interaction and on the socioeconomic position of spouses. Data were obtained via a scenario technique enabling observation of the way in which 107 Swiss families resolved 5 typical problems of equity: parents' retirement, selling a jointly held property at a special price, allocation of adolescent family members' earnings, caring for a live-in grandfather, and deciding grandchildren's inheritance. Discussion first describes the way in which integration and adaptation typologies of family interaction were constructed and their relationship with the socioeconomic status of the families. Attention is then given to the relationship between the typologies and the decision-making process concerning distributive justice. Principal results are discussed in terms of (1) choice of principles and evaluation criteria, (2) procedural justice versus material justice, (3) norms of comparison, (4) the nature of interactants' resources, and (5) forms of appropriation. It is concluded that the saliency of the need for justice is clearer in "professional" and autonomous families than in "lower middle class" families and fusional families. Findings also indicate that judgments of the equitable or inequitable nature of a situation are guided by two "regulators," not one. (RH)
