Political theorists have long argued that political participation has been a minimal requirement of democratic political systems. More recently, social scientists have turned their attention to understanding the factors that impede or promote participation. This paper examines several such hypotheses which lie within the framework of personality and social-psychological theory. Briefly stated, this author's contention is that: (1) each individual has a need to have sufficient control over relevant aspects of his life-space, which, under specified conditions, includes the political system; (2) the attempt to satisfy this need in the social world generates basic assumptive beliefs about personal control; and (3) these beliefs have important implications for political participation and the support of regimes.
To examine these contentions more fully, we first must consider the concept of political efficacy, especially as it relates to the motivation to participate in political life. It will then be possible to present a theory that links feelings of personal control in the political arena with more basic psychological needs that help to organize the personality system. Finally, we will present some exploratory data on the relation between beliefs in personal control and political participation. While these data do not directly contradict previous empirical studies, they do suggest the possibility that a substantial reorganization of the way in which political efficacy is conceptualized may be in order.
