Objective: Nowadays social participation is the most controversial and challenging subject in underdeveloped countries and the Third World, and the internal conditions in such communities plus international requirements makes its fulfillment and institutionalization a double priority. According to during development planning is not a subject that must be treated merely from physical and economical development viewpoint but is a change in the political power development of technology and rationalization of lifestyle. The experience of Islamic Revolution in 1979 from on side and the diversity of tribes in Iran and widespread immigration to cities from towns and particularly to Tehran and the juvenile nature of the country’s population and expansion of science and education on the other side renders social participation a pressing necessity There are two types of social. participation: psychological participation and sociological. In this article we are examining the theory of Rogers, a famous psychological theoretician, and are trying to experiment his thesis from the point of view of realities prevailing in Iranian community in the past several decades (from geographical, historical, social, philosophical, cultural and psychological aspects), and want to see whether that theory reflects the realities in the process of social participation in Iran or not. Method: Our method of study is a combination of library and field studies. In our field survey our statistical community is composed of the citizens of Tehran at the age of l5 years old and above. Findings: our studies have, to some extent, revealed a meaningful relationship between the individual personality features (rural subcultures) and social participation. As statistics have shown there is a meaningful relationship between rural subcultures and the mental desire for social participation whereas the relationship direction is negative. In other words the more the people are impressed by rural sub-culture, the more they are willing to participate in the society, whereas in its outward aspect there is no meaningful relationship between rural-subcultures and social participation, and this lack of relationship emanates from several factors including lack of confidence against higher institutions and lack of necessary conditions for social participation.
