Driver stress in five Spanish-speaking countries: Construct validity of the LatinSET

Introduction
Driver stress is a phenomenon many have studied in probably all five continents. It has been the focus of curiosity for all sorts of disciplines, and science has been unable to curb it, much less park it.

Objectives
This study aims to generate a unique scale that can be used in Spanish speaking countries regardless of culture or geography.

Method and Materials
A sample of 1954 drivers from Mexico, Guatemala, Costa Rica, Chile and Spain was comprised. Through this study, the original 21 items of the ISET (Stressful Situations in Transit Inventory, in Spanish) were used to carry out both an Exploratory Factorial Analysis as well as a Confirmatory Factorial Analysis.

Results
As a result, a 9 item scale was created that is valid for use in Spanish countries.

Conclusions
Although further research is warranted, the LatinSET is now valid for its use in Spanish-speaking countries.
