Abstract

The rapid growth of social commerce has transformed purchasing behavior by combining entertainment, social interaction, and online shopping. TikTok Shop is a fast-growing platform where live streaming, flash sales, countdown timers, and personalized recommendations encourage spontaneous purchases, increasing both emotional buying and post-purchase regret. This study investigates the effects of Fear of Missing Out (FoMO) and time pressure on post-purchase regret through the mediating role of impulsive buying among female fashion consumers using TikTok Shop. Guided by Stimulus–Organism–Response (S-O-R) theory, this study positions FoMO and time pressure as stimuli, impulsive buying as the organism, and post-purchase regret as the response. Data were collected from female university students in Malang City who had purchased fashion products on TikTok Shop using a quantitative PLS-SEM approach. The findings show that FoMO and time pressure significantly increase impulsive buying behavior, which in turn leads to higher levels of post-purchase regret. Moreover, impulsive buying significantly mediates the relationships between both antecedent variables and post-purchase regret. These findings extend the application of the S-O-R framework in social commerce and provide practical implications for digital marketers in designing responsible promotional strategies that balance commercial performance with long-term consumer satisfaction.

Abstract

The rapid growth of TikTok Shop has transformed online shopping by integrating social interaction, user-generated content, and purchasing activities within a single platform. However, consumers’ purchase decisions are influenced not only by direct marketing stimuli but also by psychological factors such as trust. This study aims to examine the effects of consumer involvement and Electronic Word of Mouth (e-WOM) on consumer trust and purchase decisions, as well as the mediating role of consumer trust. A quantitative approach was employed using survey data from TikTok Shop users, which were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The findings demonstrate that consumer involvement and e-WOM have positive and significant effects on consumer trust and purchase decisions. Consumer trust also positively and significantly affects purchase decisions. Furthermore, consumer trust significantly mediates the effects of both consumer involvement and e-WOM on purchase decisions, with the mediation identified as partial. These findings indicate that active consumer engagement and credible digital word-of-mouth can strengthen purchasing behavior, particularly when supported by consumer trust. The study implies that TikTok Shop sellers should enhance interactive engagement and encourage credible user-generated information to strengthen trust and facilitate purchase decisions.

Abstract

Patient satisfaction is an important indicator of healthcare quality, yet improvements in service performance do not always translate into consistently favorable patient evaluations. This study aimed to examine the effects of service quality and hospital image on patient satisfaction and patient trust, as well as the mediating role of patient trust. A quantitative survey with a causal design was conducted among 342 respondents consisting of inpatients and family members or companions. Data were collected using a structured questionnaire with a five-point Likert scale and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS. The findings show that service quality and hospital image have positive and significant effects on patient satisfaction and patient trust. Patient trust also has a positive and significant effect on patient satisfaction and significantly mediates the effects of service quality and hospital image on patient satisfaction. These findings indicate that improving service quality and strengthening hospital image should be accompanied by efforts to build patient trust. The study concludes that patient trust is an important mechanism for translating service experiences and institutional perceptions into greater patient satisfaction.
