English Background: This study challenges the common stigma that social media addiction (SMA) reflects social disconnection. Using a dual-motivation framework, we examine how self-oriented and other-oriented motives shape green information sharing (GIS) and the internalization of green consumption values (GCV) within social media communities. Methods: We analyzed cross-sectional survey data from 532 respondents in Taiwan, of whom 16.54% met the threshold for SMA.
