Using data from June to August 2024 across three Chinese regions, researchers employed standardized measures including the Children\u2019s Depression Inventory, Multidimensional Anxiety Scale for Children, Ruminative Response Scale, and Internet Addiction Test. Regularized partial correlation network analysis revealed symptom rumination and social anxiety as both core and bridging symptoms within the network structure. The overall network strength differed significantly between SES groups (high SES = 8.476 vs low SES = 8.683). Low-SES adolescents exhibited higher centrality in low self-esteem, while high-SES adolescents demonstrated higher centrality in time management and performance difficulties. Symptom rumination and social anxiety exhibited the highest strength and bridge centrality in the overall network, highlighting their key roles in linking psychological issues with PIU. SES-related network differences highlight how socioeconomic context may be associated with different psychological pathways to PIU. These findings inform a more nuanced and context-sensitive understanding of PIU etiology. However, given the limitations of the SES measure used in this study, including reliance on a single subjective item and dichotomized grouping, these observations should be interpreted with caution.<\/jats:p>","DOI":"10.1177\/21522715251372356","type":"journal-article","created":{"date-parts":[[2025,9,30]],"date-time":"2025-09-30T16:26:14Z","timestamp":1759249574000},"page":"707-716","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Network Analysis of Problematic Internet Use and Adolescent Psychological Issues: The Role of Socioeconomic Status"],"prefix":"10.1177","volume":"28","author":[{"given":"Feng","family":"Zhuo","sequence":"first","affiliation":[{"name":"School of Nursing and Rehabilitation, Shandong University, Jinan, China."}]},{"given":"Xinran","family":"Xie","sequence":"additional","affiliation":[{"name":"School of Nursing and Rehabilitation, Shandong University, Jinan, China."}]},{"given":"Li","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Nursing and Rehabilitation, Shandong University, Jinan, China."}]},{"given":"Tingting","family":"Fang","sequence":"additional","affiliation":[{"name":"School of Nursing and Rehabilitation, Shandong University, Jinan, China."}]},{"given":"Jingya","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Mental Behavior, Shandong Mental Health Center, Shandong University, Jinan, China."}]},{"given":"Ying","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Mental Behavior, Shandong Mental Health Center, Shandong University, Jinan, China."}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8289-4180","authenticated-orcid":false,"given":"Linghua","family":"Kong","sequence":"additional","affiliation":[{"name":"School of Nursing and Rehabilitation, Shandong University, Jinan, China."}]}],"member":"179","published-online":{"date-parts":[[2025,10,14]]},"reference":[{"key":"e_1_3_7_2_2","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph19137593"},{"key":"e_1_3_7_3_2","doi-asserted-by":"publisher","DOI":"10.1037\/adb0000560"},{"key":"e_1_3_7_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.dcn.2015.07.006"},{"key":"e_1_3_7_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s40429-020-00320-0"},{"key":"e_1_3_7_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajp.2025.104458"},{"key":"e_1_3_7_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0747-5632(00)00041-8"},{"key":"e_1_3_7_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.addbeh.2018.12.009"},{"key":"e_1_3_7_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chb.2013.10.017"},{"key":"e_1_3_7_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00787-021-01808-4"},{"key":"e_1_3_7_11_2","doi-asserted-by":"publisher","DOI":"10.1089\/cyber.2021.0300"},{"key":"e_1_3_7_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cpr.2023.102255"},{"key":"e_1_3_7_13_2","doi-asserted-by":"publisher","DOI":"10.1177\/13591045231221269"},{"key":"e_1_3_7_14_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.72.3.400"},{"key":"e_1_3_7_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neubiorev.2019.06.032"},{"key":"e_1_3_7_16_2","doi-asserted-by":"publisher","DOI":"10.1093\/eurpub\/ckz127"},{"issue":"5","key":"e_1_3_7_17_2","first-page":"799","article-title":"Direct and indirect effects of socioeconomic status and discrimination on subjective cognitive decline: A longitudinal study of African American women","volume":"78","author":"Simons RL","year":"2023","unstructured":"Simons RL, , Ong ML, , Beach SRH, et al.
