Changes in consumer behavior are driven by tastes and preferences that change over
time as their socioeconomic conditions change. The objective of this study was to validate the
psychometric characteristics of the e-RetailTest scale, created to measure consumer attitudes towards
online shopping in developing countries, particularly in the Peruvian market. The e-RetailTest
evaluates five variables present in the online purchase process: (a) quality of web design, (b) risk
when making a purchase, (c) customer service, (d) security and (e) satisfaction, with a total of twenty
items using a Likert scale. A total of 422 valid responses were collected from Peruvian consumers
who had had online shopping experience in the retail sector. Statistically, we worked with the
AFE exploratory factor analysis and the AFC confirmatory factor analysis. The results suggest
that this first version of the e-RetailTest presents adequate psychometric evidence to measure the
attitude of consumers towards online purchases in the retail sector in the Peruvian market. Thus, it
seeks to contribute to the advancement of the study of these important variables of Latin American
consumer behavior
