This study examined the relationship between LINE/Twitter/Instagram usage, social support networks (SSNs), and subjective well-being (SWB) among university students during the mid-late of COVID- 19 pandemic. The data fom the panel surveys conducted in May 2022 and May 2023 was analyzed by crossdelayed effects models. The results showed that 1) male students' posting frequency on LINE and female students' LINE use time improved SWB; 2) for both males and females, SWB had negative effects on Twitter use time; 3) females' LINE posting frequency and Instagram use time had negative effects while their posting frequency on Twitter had positive effects on the size of SSNs.
