PurposeThe aim of this study was to find out the factors that influenced customers' continuance usage intention of food delivery apps (FDAs) during COVID-19 quarantine.Design/methodology/approachThe information was obtained by applying an online survey to a sample of 295 residents in Tijuana, Mexico, who were repeat customers of the FDAs during COVID-19 quarantine. Exploratory factor analysis (EFA), the average variance explained (AVE) and composite reliability (CR) were conducted to ensure the validity of each construct. Multiple regression analysis was done to identify predictors of customers' continuance usage intention.FindingsBased on the Unified Theory of Acceptance and Use of Technology 2 (UTAUT-2), four constructs were included: effort expectancy, performance expectancy, food and beverage quality and price saving orientation. Multiple linear regressions were carried out to assess the relationship between the four dimensions and customers' continuance usage intention of FDAs. The results obtained show that effort expectancy, performance expectancy and price saving orientation influenced the customers' continuous usage behavior.Originality/valueThis study contributes to the body of knowledge on consumer behavior on the continuance usage intention of FDAs during the COVID-19 pandemic, which has been scarcely studied. Also, the food and beverage quality construct was proposed, and the price value construct from the UTAUT-2 theory was adapted to price saving orientation.
