The Effectiveness The Effectiveness of Students' Self-Control in Efforts to Reduce Impulsive Buying Behavior

Abstract

Humans have endless needs, including when it comes to shopping. Nowadays, shopping is not only to fulfill basic needs, but also to fulfill lifestyle. Shopping without consideration is common in late adolescents, especially students. The purpose of this study was to determine how much the effectiveness of self-control training in reducing impulsive buying in college students. This study uses quantitative research Pre-experimental design and one-group pretest-posttest design. In this study, researchers conducted a normality test using the Shpiro-Wilk test, after it was found that the data tested was normally distributed, the researchers continued the analysis using the paired sample t-test. The number of samples was 10 respondents with the criteria of active undergraduate students, aged 18-25 years who like to shop. The data collection technique uses a Likert impulsive buying scale totaling 20 items that have been tested for validity and reliability. The results of the hypothesis test state that the paired sample test value, namely, the p-value shows <0.05, which is 0.000, which means that the results of this test are statistically significant, in other words, there is a real difference between the two data groups or the effect of a variable really exists. Furthermore, effect-size r. Effect-size r is a measure that shows how much effect the intervention has on the outcome. The value of r ranges from 0 to 1, where 0.1 is considered small (small effect), 0.3 is considered medium (medium effect), 0.5 or more is considered large (large effect). Based on the results of the analysis, the effect-size r showed a value of 0.8548. This means that the intervention has a fairly large effect. This means that the intervention has a considerable effect. The higher the individual's ability to apply self-control, the lower the likelihood of individuals experiencing impulsive buying behavior. Conversely, the lower the individual's ability to apply self-control, the higher the likelihood of individuals experiencing impulsive buying behavior.
