Future studies should assess temporal order more closely, using high density longitudinal sampling strategies (i.e., more than two data collection points) to further clarify the temporal ordering of these symptom domains.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/jclp.70207","type":"journal-article","created":{"date-parts":[[2026,8,11]],"date-time":"2026-08-11T20:14:48Z","timestamp":1786479288000},"page":"1897-1907","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Examining the Directional Effects of Insomnia, Anxiety, and Depression Symptoms: Results From a Longitudinal Study Conducted During the COVID\u201019 Pandemic"],"prefix":"10.1002","volume":"82","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2256-3931","authenticated-orcid":false,"given":"Jamie","family":"Walker","sequence":"first","affiliation":[{"name":"Department of Psychological Science University of Arkansas Fayetteville Arkansas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9836-9946","authenticated-orcid":false,"given":"Ana J.","family":"Bridges","sequence":"additional","affiliation":[{"name":"Department of Psychological Science University of Arkansas Fayetteville Arkansas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4826-8498","authenticated-orcid":false,"given":"Alexandria","family":"Muench","sequence":"additional","affiliation":[{"name":"Behavioral Sleep Medicine Program University of Pennsylvania Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael L.","family":"Perlis","sequence":"additional","affiliation":[{"name":"Behavioral Sleep Medicine Program University of Pennsylvania Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0787-5630","authenticated-orcid":false,"given":"Ivan","family":"Vargas","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Notre Dame Notre Dame Indiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,11]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.5665\/SLEEP.2810"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291721004062"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/J.JAD.2011.01.011"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1389-9457(00)00065-4"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/smi.3016"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/J.CPR.2018.05.006"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1177\/1073191121994164"},{"key":"e_1_2_9_9_1","unstructured":"Centers for Disease Control and Prevention.2022.CDC Museum COVID\u201019 Timeline.
