Developmental psychopathology can be viewed as a macroparadigm within which to integrate theoretical and empirical contributions stemming from other paradigms such as biomedical, behavioral, psychodynamic, cognitive, sociological, and family systems. By highlighting the interconnections among these different approaches and providing an overarching conceptual map, a macroparadigm of developmental psychopathology can stimulate hypotheses that converge on common issues. In addition to its role in integrating research and theory, a macroparadigm of developmental psychopathology has potential applications for training, prevention, services, and the planning of services for troubled children. Because activities in all these areas are currently fragmented by different professional disciplines, personal philosophies and agendas, sources of support, and types of clientele, it is essential to find common denominators on which such activities can be based. This discussion outlines ways in which developmental approaches can span different professions and settings. (RH)
