Social media has grown to be a large part of our virtual connectedness online. However, with this growth in digital connection, we have also become connected with digital entities that run them (social media). Borrowing from the concept of interpersonal responsiveness, researchers have found that users perceive their algorithm to be responsive to their needs and sensitive to their identity have a greater sense of well-being online and media enjoyment. However, the mechanisms for which these connect with one another (responsiveness predicting subjective well-being) remain to be disentangled. Guided by self-determination theory, this study examines whether autonomy, competence, and relatedness satisfaction through TikTok use mediate the associations between perceived algorithm responsiveness and insensitivity and satisfaction with life. With an online survey (N = 385), our study found that greater responsiveness is associated with greater life satisfaction mediated through greater relatedness satisfaction. However, greater competence satisfaction was associated with lower life satisfaction. Future research and current limitations in light of our findings are discussed.
