Understanding their interplay, particularly at the symptom level, is critical for developing effective interventions. Objective: To examine longitudinal relationships between loneliness and depressive symptoms during late childhood, aiming to identify symptom-level interactions and directional effects. Participants and Setting: A total of 4333 children (Mage = 11.06, SD = 0.73; 50.8% girls) from the NLSY79 Children and Young Adults survey participated, with data collected over two years. Methods: A cross-lagged panel network (CLPN) model was employed to analyze symptom-level associations between loneliness and depressive symptoms. This approach combines network analysis and cross-lagged panel modeling, allowing for the estimation of both autoregressive effects (stability of symptoms over time) and cross-lagged effects (directional relationships between symptoms across time points). Results: The longitudinal network suggests the following: (1) a reciprocal link between loneliness and both sadness and parental pressure; (2) a forward effect of loneliness on anxiety and being busy; (3) the loneliness-reducing effect of prior happiness and loneliness-increasing effect of boredom. Conclusions: The findings highlight the complex interplay between loneliness and depressive symptoms, emphasizing reciprocal and unidirectional effects at the symptom level. These insights underscore the need for targeted, symptom-focused interventions to address loneliness and its impact on adolescent mental health.<\/jats:p>","DOI":"10.3390\/ejihpe16060078","type":"journal-article","created":{"date-parts":[[2026,6,4]],"date-time":"2026-06-04T01:08:02Z","timestamp":1780535282000},"page":"78","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Longitudinal Interplay Between Loneliness and Depressive Symptoms During Late Childhood: Cross-Lagged Panel Network Analyses"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9790-3772","authenticated-orcid":false,"given":"Pawe\u0142","family":"Grygiel","sequence":"first","affiliation":[{"name":"Faculty of Philosophy, Jagiellonian University, Golebia 24, 31-007 Cracow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4891-7075","authenticated-orcid":false,"given":"Sylwia","family":"Opozda-Suder","sequence":"additional","affiliation":[{"name":"Faculty of Philosophy, Jagiellonian University, Golebia 24, 31-007 Cracow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7967-9022","authenticated-orcid":false,"given":"Roman","family":"Dolata","sequence":"additional","affiliation":[{"name":"Faculty of Education, University of Warsaw, Mokotowska 16\/20, 00-561 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,31]]},"reference":[{"key":"ref_1","unstructured":"Abela, J.
