This article “strengthens the core” of uses and gratifications theory by offering reliance, credibility, and interactivity as measures of social media use. Although reliance is recognized as a predictor of media use, it has not been extensively studied in regard to social media. The findings indicate that reliance is the strongest predictor of motivations for using social network sites (SNS) and blogs but is a weak predictor of Twitter use. Although results are mixed on whether credibility influences media use, credibility is a significant and positive predictor of blog and SNS use. Importantly, this study introduces interactivity as a predictor of social media use. Interactivity is a strong and significant influence on SNS and Twitter but only weakly affects blog use. Results from an online survey support reliance as a measure of media use and suggests that credibility and interactivity are also effective measures that should be included in future studies.

加强核心

本文通过提供依赖、可信度和交互性作为社交媒体使用的衡量标准，“加强了使用和满足理论的核心”。尽管依赖被认为是媒体使用的预测因素，但尚未对社交媒体进行广泛研究。研究结果表明，依赖是使用社交网站 (SNS) 和博客动机的最强预测因素，但对 Twitter 使用的预测较弱。尽管关于可信度是否影响媒体使用的结果喜忧参半，但可信度是博客和 SNS 使用的重要且积极的预测因素。重要的是，这项研究引入了交互性作为社交媒体使用的预测指标。交互性对 SNS 和 Twitter 有强大而重要的影响，但对博客的使用影响很小。
