Latin American societies show lower levels of political trust when compared to other regions of the world. The lack of trust in institutions can led to ineffective management of public affairs, social crises, lack of transparency, economic problems and even difficulties in countering pandemics. The objective of this work is to build an index (LADI) that provides a measure of the level of perceived distrust in the institutions of the different Latin American countries and its variations over the period from 2008 to 2018. The data used for this analysis are of a subjective nature and come from the series of surveys provided by Latinobarómetro. To develop the analysis, we have used a quantitative approach of a partially non-compensatory aggregative type, known as Adjusted Mazziotta and Pareto Index. The results show a generalized increase of distrust in the years 2017 and 2018 for several Latin American countries. On the other hand, in countries where the rule of law is more consolidated, a best perception of the functioning of democracy emerges.

与世界其他地区相比，拉丁美洲社会的政治信任度较低。对机构缺乏信任可能导致公共事务管理不力、社会危机、缺乏透明度、经济问题甚至抗击流行病的困难。这项工作的目标是建立一个指数（LADI），衡量不同拉丁美洲国家机构的感知不信任程度及其在 2008 年至 2018 年期间的变化。用于此分析的数据是具有主观性，来自Latinobarómetro提供的一系列调查。为了进行分析，我们使用了部分非补偿性聚合类型的定量方法，称为调整后的马齐奥塔和帕累托指数。结果显示，2017 年和 2018 年，一些拉丁美洲国家的不信任普遍增加。另一方面，在法治更加巩固的国家，人们会出现对民主运作的最佳认识。
