Abstract:
In the present world where everything seems to happen digitally, the role of social media
cannot be underestimated since it is now an inseparable part of consumers' lives. The use of social media by Generation Z consumers in the Western Province of Sri Lanka can
definitely be called extensive, and Instagram is one of the social media that is gaining more
popularity. With time, Instagram has become not only another tool for socializing but a good
means of digital marketing communication since it enables companies to communicate
directly with their consumers. One of such methods implemented on Instagram is its Reels
advertisements, which can be viewed as short video clips accompanied by music and
interesting stories. Consequently, these advertisements significantly influence consumers'
attitudes and decisions about purchasing. Therefore, this study aims to examine the impact
of Instagram Reels advertisements on the impulsive buying behaviour of Generation Z
consumers towards fashion accessories in the Western Province of Sri Lanka. A quantitative
research approach was adopted and data were collected from a sample of 250 Generation Z
respondents through a structured questionnaire using a convenient sampling technique. Four
independent variables are investigated within this study, which include entertainment,
informativeness, credibility and personalization, with impulsive buying behavior being
considered as the dependent variable. Data were analyzed using descriptive statistics,
reliability analysis, correlation analysis, multiple regression analysis, and an independent-
samples t-test in SPSS. It was found that informativeness and personalization are the two
factors which significantly impact impulsive buying behavior, with informativeness being
established as the most powerful factor. Entertainment and credibility also show positive but
comparatively weaker effects. In addition to this, no significant difference was found in
impulsive buying behavior between men and women. This study helps businesses identify
which feature of Instagram Reels advertisements should be focused on when targeting
Generation Z consumers toward fashion accessories in the western province of Sri Lanka.
