An alternative set of constructs for intergenerational relation(ship)s, Post-Solidarity, is presented and empirically tested. Post-Solidarity comprehends not only traditional positive and consensual dimensions of within-primary-group (or "family") relation(ships) but also the ambivalence, conflict, fluidity, and indeterminacy so characteristic of social life in Postmodern America (and, perhaps, Western Europe). A series of measurement, mean-comparison, and regression analyses, evaluating the nomothetic and predictive viability of Post-Solidarity against the currently dominant conceptualization of intergenerational relation(ship)s as either solidary or fatally conflictual, generated results that suggest preliminary support for Post-Solidarity as an additive and more appropriate conceptualization of contemporary intergenerational relation(ship)s.
