This research aims to answer the main question: What are the basic components of political trust? So that we can explain the effectiveness of these components in the fluctuations of political trust in Iran from 1989 to 2011. The research method is a combination of meta-synthesis, secondary analysis of three waves of national surveys conducted in 1990, 1991, and 2005, and finally interviews with political science experts and elites. Five components of economic efficiency, inherent characteristics of executive duties, efficiency of foreign relations, party dynamics, and finally cultural issues were identified, and prioritizing and focusing on them leads to the emergence of prominent indicators of political trust. Within the framework of the concepts presented by scholars such as Britzer and Easton regarding authority as a creator of positive attitudes in society, Huntington-Nielson's theories on the main factors of political trust formation, and Zatomeka's view on the conditions for producing trust in society, in the present study we have evaluated the status of the identified components based on different approaches to them. This was operationalized through the analysis of the interview contents to introduce the approaches that cause the emergence of more characteristics of political trust. Finally, a model of appropriate approaches for the formation and expansion of political trust is presented.
