Developmental psychopathology and family systems theory are distinct approaches that have flourished in relative isolation from each other. Contributing to their distinctiveness, important differences exist between the approaches in the primary unit of analysis. Whereas developmental psychopathology commonly focuses on individual development as the main unit of analysis, the whole family unit is the central object of study in family systems approaches. Accordingly, the primary objective of developmental psychopathology is to understand the nature, origins, and sequelae of individual patterns of adaptation and maladaptation over time~Cicchetti, 1993; Sroufe & Rutter, 1984!. In contrast, the principal goal in the family systems approach is to achieve a rich characterization of the interplay among relationships and individuals in the whole family unit, with a specific focus on identifying relationship structures, interpersonal boundaries, power distributions, and communication pat-terns~Cox & Paley, 1997; Minuchin, 1985!.
