This study aimed to explore the moderating role of social networking sites (SNS) use in the link between identity commitment development and psychological functioning in a sample of Portuguese emerging adults. Cross-sectional survey data were collected from 251 participants (71.3% women), aged 18–30 years ( M = 22.33, SD = 3.31). Self-report questionnaires were used to measure identity commitment-making (commitment-making and identification with commitment), SNS use (perception of feed refresh frequency), and psychological functioning (anxiety and depressive symptoms). Results showed that feed refresh frequency acts as a moderator with a distinct role in the associations between each identity commitment dimension and psychological functioning. Specifically, with the increased frequency of feed refresh, the relation between commitment-making and psychological symptoms becomes negative (for those who refresh feed more frequently, the presence of commitments was associated with lower levels of anxiety and depressive symptoms). On the other hand, the negative relation between identification with commitment and psychological symptoms becomes weaker with an increase in the frequency of feed refresh (for those who refresh feed more frequently, identifying with and embracing the commitments they already made was not associated with psychological symptoms). Overall, our results suggest that refreshing the SNS feed seems to boost the effect of commitment-making in psychological functioning and simultaneously hinder the effect of identification with commitment on psychological functioning. Ultimately, this study calls for further research on emerging adults’ identity development in the digital age, which can inform prevention/intervention actions for promoting youth media literacy and psychological adjustment.
