Social media, such as Instagram or Twitter, offer materialists new opportunities to pursue and satisfy materialistic needs and wants. Previous work has already shown that materialism is positively related to social media use to compare their possessions with those of other users and to accumulate digital possessions (in the form of friendships or followers). However, materialism use of social media does not only bring benefits but could also negatively impact satisfaction with life (as a marker of subjective well-being) under certain conditions. In an online study (N = 1230), we examined the extent to which materialism on social media is associated with lower satisfaction with life. Evaluation of a sequential mediation model revealed that highly materialistic participants exhibited higher social comparison orientation, stronger associations with passive social media use as well as social media addiction, and thus reported higher stress experience resulting in lower satisfaction with life. Further results as well as limitations of the study and an outlook are discussed. 1. Introduction Materialism, a positive attitude towards possessions and material things as well as the desire to constantly increase them, is a psychological trait that has become more and more common since industrialization and is currently increasing [1-3]. Today, in the digital age, it is easier than ever to satisfy one's materialistic needs: Through the Internet, possessions can be accumulated quickly (online shopping) as well as displayed and compared with others (via social media). The global smartphone 2023 shows that around 4.76 billion people use social media (cf. [3]) with a rising trend. Thus, materialists can present their possessions to billions of users and become known at the same time. However, comparisons on social media also entail serious risks. Studies show that passive use of social media, in which the focus is on reading comments, viewing profiles and the newsfeed, can lead to less well-being, satisfaction with life, and lower mental health [4-5]. This can be especially the case
