This pattern of co-occurrence describes how digital behaviors and mental health states are distributed across participants. Future research should test these pathways longitudinally and across diverse cultures. Practically, interventions targeting need satisfaction and self-acceptance rather than merely reducing screen time could more effectively mitigate loneliness in higher education settings.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpsyg.2026.1944813","type":"journal-article","created":{"date-parts":[[2026,9,11]],"date-time":"2026-09-11T05:30:23Z","timestamp":1789104623000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Problematic social networking use and loneliness among college students: a serial mediation model of basic psychological need satisfaction and self-acceptance"],"prefix":"10.3389","volume":"17","author":[{"given":"Xiuju","family":"Tian","sequence":"first","affiliation":[{"name":"College of Psychology, Zhejiang Normal University, Jinhua","place":["Zhejiang, China"]},{"name":"Mental Health Education Center, Huzhou Normal University, Huzhou","place":["Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lijun","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Psychology, Zhejiang Normal University, Jinhua","place":["Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,11]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"365","DOI":"10.4324\/9781315757421","article-title":"Structural equation modeling with AMOS: Basic concepts, applications and programming.","volume":"5","author":"Abd-El-Fattah","year":"2010","journal-title":"J.
