This study aims to determine the influence of cultural factors on consumer behavior in online shopping, as well as the impact of social, personal, and psychological factors on consumer behavior in online shopping. Additionally, this study seeks to examine the influence of these factors—cultural, social, personal, and psychological—on consumer decision-making in online shopping. Furthermore, it aims to explore the relationship between consumer behavior and consumer decision-making in online shopping. The data were collected through questionnaires involving a sample of 114 respondents. Data analysis was conducted using Structural Equation Modeling (SEM) with the AMOS application. The results indicate that stronger cultural factors positively influence consumer behavior, with a regression coefficient of 0.786. Similarly, stronger social factors enhance consumer behavior, with a regression coefficient of 0.994. Personal factors also have a positive effect on consumer behavior, with a regression coefficient of 0.518, while psychological factors contribute to consumer behavior with a regression coefficient of 0.214. In terms of decision-making, stronger cultural factors accelerate consumer decision-making, with a regression coefficient of 0.648. Social factors also expedite consumer decision-making, with a regression coefficient of 0.404. Personal factors play a role in speeding up consumer decision-making, with a regression coefficient of 0.395. Psychological factors, however, have a minimal effect on decision-making, with a regression coefficient of 0.008. Finally, stronger consumer behavior leads to faster decision-making, with a regression coefficient of 0.190.
