This study compared the responses of husbands and wives regarding decision-making in two cultures, Greek and American, as obtained by two different sampling techniques. The American data were obtained from 160 couples who lived in the Detroit area and who had a child under 6 years old. The Greek sample was 133 wives and 117 husbands, none of whom was a spouse of another member of the sample. These 250 adults were from Athens, Greece. The Detroit couples were asked if the husband, the wife, or both were responsible for the making of 14 specific decisions. The Greek subjects were asked whose opinion usually prevailed in eight decisional areas. Of the responses made by the Detroit couples, clear disagreement occurred between spouses in 55 percent; slight disagreement, in 21 percent; and complete agreement, in only 24 percent. In comparing the responses of the Greek participants, significant differences in perspective were discovered between the men and women. The overall findings demonstrated the unreliability of generalizing the opinions of wives, which comprised a good deal of family survey data, to the husbands. A number of methodological procedures are suggested with a view to refining the study of familial decision-making. (WD)
