Against the background of interdisciplinary behavior theories, and based on extensive empirical research, an interdisciplinary model for behavior analysis and intervention is proposed. The model is based on needs, perceptions and knowledge, which, as intervening variables, represent the direct causes or potential change forces. It lends itself for analyzing behavior in situation analyses and for planning change strategies focused on individuals, groups or communities.

The article gives a brief overview of the rationale behind the model and describes the critical behavior determinants, which, if analyzed, are assumed to provide an insight into adoption behavior and, consequently, provide a basis for behavior modification.
