Behavior change models have been the dominant paradigm in the field of development communication. Different theories and strategies shared the premise that problems of development were basically rooted in lack of knowledge and that, consequently, interventions needed to provide people with information to change behavior.
The early generation of development communication studies was dominated by modernization theory. This theory suggested that cultural and information deficits lie underneath development problems, and therefore could not be resolved only through economic assistance (a la Marshall Plan in post-war Europe). Instead, the difficulties in Third World countries were at least partially related to the existence of a traditional culture that inhibited development. Third World countries lacked the necessary culture to move into a modern stage. Culture was viewed as the “bottleneck” that prevented the adoption of modern attitudes and behavior. McClelland (1961) and Hagen (1962), for example, understood that personalities determined social structure. Traditional personalities, characterized by authoritarianism, low self-esteem, and resistance to innovation, were diametrically different from modern personalities and, consequently, anti-development. These studies best illustrated one of modernization’s central tenets: ideas are the independent variable that explains specific outcomes. Based on this diagnosis, development communication proposed that changes in ideas would result in transformations in behavior. The underlying premise, originated in classic sociological theories, was that there is a necessary fitness between a “modern” culture and economic and political development. The low rate of agricultural output, the high rate of fertility and mortality, or the low rates of literacy found in the underdeveloped world were explained by the persistence of traditional values and attitudes that prevented modernization. The goal was,
