Latent profile analysis (LPA) was conducted using 16 symptom indicators derived from the Hamilton depression rating scale (HDRS), Hamilton anxiety rating scale (HAMA), and Pittsburgh sleep quality index (PSQI).

Recorded family trauma\/stressor exposure and violent incident exposure were associated with higher odds of Profile 3 membership relative to Profile 1, and these associations remained significant after neuroendocrine markers were added. Higher standardized testosterone (T) showed a modest association with Profile 3 membership, whereas FT3 showed only a marginal association. However, adding neuroendocrine markers did not significantly improve model fit beyond trauma\u2010related variables.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>LPA identified three clinically interpretable symptom profiles in adolescent MDD, including a profile characterized primarily by elevated PSQI\u2010assessed subjective sleep disturbance. Recorded trauma\/stressor exposure was associated with the high overall symptom profile, whereas neuroendocrine markers showed limited incremental value. These findings highlight multidimensional symptom profiling and trauma assessment in adolescent depression, while suggesting that neuroendocrine findings should be considered exploratory.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1155\/da\/9254081","type":"journal-article","created":{"date-parts":[[2026,7,24]],"date-time":"2026-07-24T10:47:45Z","timestamp":1784890065000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Latent Symptom Profiles in Adolescents With Major Depressive Disorder: Subjective Sleep Disturbance and Biopsychosocial Correlates"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-8123-0308","authenticated-orcid":false,"given":"Jianyu","family":"Liu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinyi","family":"Cao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengmeng","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-2850-4839","authenticated-orcid":false,"given":"Yin","family":"Lin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8636-1947","authenticated-orcid":false,"given":"Yan","family":"He","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,24]]},"reference":[{"key":"e_1_2_13_1_2","unstructured":"World Health Organization (WHO) Adolescent Mental Health 2020 https:\/\/lib.umslib.v.zzu.edu.cn\/https\/vpn\/1556\/P75YPLUYNBYT64LPPE\/news%E2%80%93room\/fact%E2%80%93sheets\/detail\/adolescent%E2%80%93mental%E2%80%93health Accessed July 20 2020."},{"key":"e_1_2_13_2_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0069637"},{"key":"e_1_2_13_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jad.2018.11.043"},{"key":"e_1_2_13_4_2","doi-asserted-by":"crossref","first-page":"1056","DOI":"10.1016\/S0140-6736(11)60871-4","article-title":"Depression in Adolescence","volume":"379","author":"Thapar A.","year":"2012","journal-title":"Lancet"},{"key":"e_1_2_13_5_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0192300"},{"key":"e_1_2_13_6_2","doi-asserted-by":"publisher","DOI":"10.1155\/2015\/581976"},{"key":"e_1_2_13_7_2","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291726103183"},{"key":"e_1_2_13_8_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pmed.1004510"},{"key":"e_1_2_13_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02289845"},{"key":"e_1_2_13_10_2","volume-title":"Latent Structure Analysis","author":"Lazarsfeld P.
