Abstract
As one of the first true family theories, family development theory helps explain competing and complimentary development among family members. However, assumptions of universality and other limitations have reduced its usefulness. We propose multidimensional family development theory, a reconceptualization that includes modifications to increase utility and usability for researchers and practitioners alike. From previously composite stages, we derive four dimensions of development: personal, vocational, couple, and generative. We discuss each dimension, the relationship of dimensions within individuals, and how the dimensions exert reciprocal influence individually and across the entire family. Mechanisms for the development of the individual and family are put forth. Roles and stages are discussed within the context of the developmental dimensions. The role and influence of culture is explicated. Links between process and diversity in terms of development are posited. We discuss how the theory can be applied in research and clinical settings.
