ABSTRACT
The impact caused by COVID-19 and its effects on the national economy revealed the little or no capacity of companies to cope with this situation, causing temporary and, in some cases, permanent closure in various sectors. Given this situation, this paper aims to determine the validity and reliability of an instrument to measure business resilience in small and medium-sized companies based on the perception of their directors, managers and/or owners. The methodology was based in a quantitative approach, exploratory scope, and non-experimental design. The instrument was initially composed of 48 items grouped into three dimensions of resilient capacities: foresight, adaptation, and recovery, which was applied to a sample of 346 companies established in Ciudad del Carmen, Campeche, Mexico. According to the results, it is concluded that the analyzed instrument meets the reliability and construct validity criteria, highlighting the reduction to 20 items with factor loads between 0.556 and 0.811 grouped into three factors that explain 66.97% of the total variance. © 2023, Universidad del Zulia.
