Live-streaming commerce business is growing as the consumption of video content and Smartphone shopping increases. This study examines the following three aspects: whether para-social interaction influences perceived interactivity; whether seller trust affects satisfaction with the experience; whether relationships are controlled by a moderated mediator of self-image congruity. An online survey was conducted with 203 women aged 20-30 years. They were asked to respond to the survey after watching a beauty category live-streaming commerce broadcast. The results revealed that the para-social interaction had a significant effect on perceived interactivity, seller trust and satisfaction with the experience. The findings also indicated that the perceived interactivity and seller trust mediated the relationship between para-social interaction and satisfaction with the experience. Regarding the mediated moderation effect of self-image congruity, it was statistically significant between para-social interaction and perceived interactivity through seller trust. A higher level of consumer’s self-image congruity influenced the greater effect of para-social interaction on live commerce experience. This study makes important theoretical contributions to the para-social interaction in mobile commerce industry by emphasizing the mediating role of perceived interactivity and seller trust. This is achieved by examining the moderating effects of self-congruity on satisfaction with the experience. The results also verify the seller’s crucial role in live-streaming commerce market which leads to the consumers greater fulfillment.

This study investigated how the image congruity of social commerce and fashion brand types affects purchase intention and how trust and price sensitivity moderate this relationship. National brands, private brands, and non-brands were used as brand types in the present study. The online survey method was used to gather the data, and 232 data samples were analyzed. The results of the research were as follows. Consumers perceived greater image congruity between social commerce and nonbrands, followed by private brands and national brands. The significant perception differences were examined by comparing the mean values. There was a significant positive effect of image congruity of social commerce and non-brands on purchase intention. However, insignificant effects were found for image congruity between social commerce and private brands and national brands. In addition, trust and price sensitivity positively predicted social commerce purchase intention. A significant moderating effect of trust was found on the relationship between purchase intention and image congruity of social commerce and non-brands. A moderating effect of price sensitivity was found on the relationship between purchase intention and image congruity of social commerce and private brands. The findings of the present study offer valuable insights into social commerce concerning implementing diverse fashion brands as well as academic and practical implications.

The study aims to investigate the effects of media and self-image congruity of ideal body image on the dieting and exercising behaviors of Korean and U.S. female college students. This study focuses on the concept of self-image congruity in order to examine how respondents perceive actual and desired self-images compared to an ideal female body image selected by respondents. A self-administered survey was conducted, resulting in 331 total responses (194 from Korean students and 137 from U.S. students). The data were analyzed through descriptive analysis, t-test, exploratory factor analysis, and regression analysis using SPSS 23.0. The findings revealed significant differences between Korean and U.S. female college students. U.S. students were more exposed to body image ideals in the media than Korean students; however, Korean female students valued the information regarding ideal body image conveyed by the media more than U.S. respondents. Among Korean female students, exposure to media messages regarding ideal body image and media importance had significant effects on desired self-image congruity, while these factors were not significant among U.S. students. However, there was a negative effect of media exposure on actual self-image congruity among U.S. respondents only. Additionally, the study uncovered that Korean students manage their body image through dieting behaviors while U.S. respondents manage body image through exercise behaviors (weight training as well as cardiovascular exercise). The study provides further support for self-image congruity, which extends its applications to the body image field.

The purpose of this study was to investigate the effect of congruency of parent brand image with self-image, perceived risk, and product knowledge on the attitude towards extended product in fashion brand extension. A survey questionnaire was used to collect data from 170 female college students and collected data were subjected to descriptive analysis and regression analysis using SPSS Window program. The results of this study showed that the congruency of parent brand image with self-image and perceived risk had a positive effect on attitude towards extended product, whereas product knowledge had a negative effect on attitude towards extended product in fashion brand extension. Also, the congruency of parent brand image with self-image had a positive effect on the attitude towards extended product in fashion brand extension with positive moderating effect of perceived risk and negative mediating effect of product knowledge.
