چرا کاربران سیار به خدمات شبکه های اجتماعی گوشی های هوشمند اعتماد می کنند؟ یک روش PLS-SEM  Why mobile users trust smartphone social networking services? A PLS-SEM approach

1. Introduction Smartphones may provide people with not only voice communications but various innovative and exciting smartphone applications (apps) to fulfill important requirements of personal information services (Pitt, Parent, Junglas, Chan, & Spyropoulou, 2011). In addition to more timely content and speedy response, accessing the Internet through smartphones allows users to extend their mobile activities to social networking services (SNS; e.g., Facebook) to access and share information on the go (Pitt et al., 2011). Many mobile users would like to use smartphone SNS that specifically offer access to travel websites that give updated location-based information and advices regarding scenic spots, transportation, accommodation, events and activities, dining and so on (Lyu & Hwang, 2015). Online social services require users to provide personal information such as names, pictures, personal interests, and personal contact details (Gunawan & Huarng, 2015). Users may share private information intensively to maintain social relationships, find users with similar interests, and acquire knowledge through SNS. This situation may result in security issues regarding trust and privacy concerns. Prior research studies user behavior regarding new technology to understand users’ intention and acceptance of social media. In terms of trust-based issues and adopters’ privacy concerns, the potential influencing factors in user behavior still deserve further investigation (Al-Debei, Al-Lozi, & Papazafeiropoulou, 2013). Thus, investigating critical factors that affect mobile users’ perceptions of smartphone SNS from the perspectives of privacy concerns, perceived risk, and trust is very valuable. Following this introduction, Section 2 contains the theoretical framework. Section 3 describes methodology. Section 4 presents the findings. Section 5 offers discussions with limitations and suggestions for future research.
