Excessive use of new technologies appears to be potentially addictive for a minority of young people. The aim of the present study was to examine the relationship between personal environment factors (self-esteem and subjective wellbeing) and behaviors (social network site [SNS] intensity and smartphone addiction) drawing upon the Social Cognitive Theory and utilizing structural equation modeling. The sample comprised 734 undergraduate Business School students. Findings indicated that young people tend to use SNSs to enhance their extrinsic outcome expectation (network size) rather than intrinsic one (subjective well-being). Based on our knowledge, the present study is the first to address SNS usage behavior to assess extrinsic and intrinsic factors separately. Results also show that high SNS intensity is associated with high levels of smartphone usage, which decreases the individuals’ level of subjective wellbeing. It is also proved that low self-esteem causes smartphone addiction. Lastly, there is a weak but significant relation between SNS intensity and network size is also found. Overall, the present study contributes to our understanding of problematic smartphone and social media use.

土耳其大学生社交媒体强度，智能手机上瘾与主观幸福感之间的关系

对少数年轻人来说，过度使用新技术可能会上瘾。本研究的目的是利用社会认知理论并利用结构方程模型研究个人环境因素（自尊和主观幸福感）与行为（社交网站[SNS]强度和智能手机上瘾）之间的关系。样本包括734名商学院本科生。研究结果表明，年轻人倾向于使用SNS来提高他们的外在结局期望（网络规模），而不是内在结局（主观幸福感）。基于我们的知识，本研究是第一个解决SNS使用行为以分别评估外部和内部因素的研究。结果还表明，高SNS强度与高水平的智能手机使用率相关，从而降低了个人的主观幸福感水平。还证明，自尊心低会导致智能手机成瘾。最后，SNS强度与网络规模之间存在弱但重要的关系。总体而言，本研究有助于我们理解有问题的智能手机和社交媒体的使用。
