Validation of the sudden purchase behavior model of customers in the service sector

The purpose of this study was to validate the model of sudden purchase behavior of customers in the service sector, which was validated using factor analysis approach and covariance-based modeling technique. The statistical population of this study included various real and legal customers who referred to Ofogh Kourosh stores in Tehran who went to the stores to buy. Of these, 384 people answered the questionnaire. The sampling method in the first stage was done in a cluster and stores were selected and in the second stage a questionnaire was given to customers to answer randomly. The instrument used in this research was a questionnaire with 178 items in four dimensions and 46 components to assess the validity of the research instrument was the construct validity method and according to the qualitatively extracted factor network, the confirmatory factor analysis technique was used, in other words to assess validity. Factor Measurement tools The main research factor (design and validation of the model of customers' sudden buying behavior in the service sector) was the factor analysis approach and covariance-based modeling technique. The results of the study showed that the underlying causes and factors affect the strategies to increase purchases and strategies to reduce the negative consequences of sudden buying behavior.
