The research proposal will aim at examining the relationship between the features of platform design and user autonomy, value co-creation, and adoption intention in social media applications. Social media are increasingly reliant on interface-level functionality such as digital nudges, personalization, and delivering content according to algorithms; however, no studies have been conducted on the psychological and behavioral outcomes of these functionalities in non-Western cultures. The Self-Determination Theory and Service-Dominant Logic-based study develops a single model that determines the effect of exposure to digital nudges, perceived personalization, privacy concerns, and cognitive overload on the perceived autonomy, which, in its turn, results in customer-to-customer, functional, and hedonic values co-creation behaviors. The study design adopts a quantitative one and involves. an online survey of the active social media users in Pakistan, the data of which were processed in terms of structural equation modeling. The research will probably contribute to the body of literature on digital nudging and social media adoption, and also offer a practical contribution to the design of autonomy-supportive and sustainable encounters on a platform by focusing on the processes of autonomy and value co-creation
