Social class and race differences in family interaction: pathological, normative, or confounding methodological factors?

The interaction patterns of 64 well-adjusted family triads, divided into eight equal groups by race, social class, and sex of adolescent, were assessed across observational and self-report measures of family affect, conflict, and dominance. Any social class or race differences similar to those of prior research could not be described as deficits since all families met extensive criteria to assure favorable psychosocial adjustment. However, in contrast to much extant literature, statistical analyses revealed few social class or race effects. In light of the present strict methodological controls, it is suggested that previous findings of race and social class differences might have resulted from uncontrolled sampling, procedural, or measurement factors.
