Purpose The purpose of this paper is to design and test a conceptual model integrating uses and gratifications (UGT), self-image congruity (SIC), and theory of planned behavior (TPB) theories to identify the drivers that lead users to develop intentions to purchase clothing products through social networking sites (SNS). Design/methodology/approach Using an online questionnaire, data were collected from customers of clothing products who visit the SNS of their preferred clothing brands (n=1,003). Empirical results, using partial least squares regressions, were used to test the conceptual model. Findings The results supported the model and showed, as the main result, that purchase intention through the use of SNS is positively affected by intentions to use SNS and SNS use. SNS use is influenced by intentions to use SNS and by UGT. Intentions to use SNS are positively affected by UGT, attitude and perceived behavioral control (PBC). Attitude is positively influenced by UGT, SIC, PBC and subjective norm. Social implications These findings reveal that the critical elements in achieving purchase intentions in users through SNS include obtaining their participation by managing the SNS according to users’ self-image and offering useful gratifications. Originality/value This paper integrates theories of SIC, UGT and the TPB in a context of technology post-adoption to understand users’ purchase intentions through SNS. By establishing this novel theoretical integration approach, this paper furthers insight into purchase intentions through SNS.

Purpose The purpose of this paper is to investigate the intention to purchase products through clothing brands’ social network sites (SNS) based on the theory of planned behavior and uses and gratifications theory (U&G), and the moderating effects of self-image congruity (SIC). Design/methodology/approach Data were collected from 1,003 followers of their favorite clothing brands’ SNS. Data analysis was performed using structural equation modeling (SEM) and multi-group SEM analysis. The models were estimated from the matrices of variances and covariances by the maximum likelihood procedure using EQS 6.1. Findings The results highlight the positive impact of U&G on attitude, SNS intentions and SNS use, and U&G, SNS intentions and SNS use were seen to be the main antecedents predicting purchase intentions. Furthermore, SIC was found to have moderating effects between SNS attitude and SNS intentions and between SNS intentions and SNS use. Practical implications This research can help clothing brands understand the need to generate brand beliefs, and to develop contents or events to help accomplish the transition from use to purchase. Originality/value This research contributes to the literature by providing a better understanding of intention to use and purchase intention through clothing brands’ SNS pages.
