Six trajectories described PTSD over time: low\u2010stable (48.9%), moderate\u2010stable (28.3%), moderate\u2010increasing (8.2%), high\u2010stable (6.0%), high\u2010decreasing (6.6 %), and very high\u2010stable (2.0%). To examine factors associated with improving or worsening PTSD symptoms, groups with similar intercepts, but different trajectories were compared using bivariate analyses and logistic regression. The adjusted odds of being in the moderate\u2010increasing relative to the moderate\u2010stable group were significantly greater among enrollees reporting low social integration (<jats:italic>OR<\/jats:italic> = 2.18), WTC exposures (range = 1.34 to 1.53), job loss related to the September 11, 2001 disaster (<jats:italic>OR<\/jats:italic> = 1.41), or unmet mental health need\/treatment (<jats:italic>OR<\/jats:italic> = 4.37). The odds of being in the high\u2010stable relative to the high\u2010decreasing group were significantly greater among enrollees reporting low social integration (<jats:italic>OR<\/jats:italic> = 2.23), WTC exposures (range = 1.39 to 1.45), or unmet mental health need\/treatment (<jats:italic>OR<\/jats:italic> = 3.42). The influence of severe exposures, scarce personal\/financial resources, and treatment barriers on PTSD trajectories suggest a need for early and ongoing PTSD screening postdisaster.<\/jats:p>","DOI":"10.1002\/jts.22090","type":"journal-article","created":{"date-parts":[[2016,3,8]],"date-time":"2016-03-08T23:54:56Z","timestamp":1457481296000},"page":"158-166","source":"Crossref","is-referenced-by-count":50,"title":["Trajectories of PTSD Among Lower Manhattan Residents and Area Workers Following the 2001 World Trade Center Disaster, 2003\u20132012"],"prefix":"10.1002","volume":"29","author":[{"given":"Alice E.","family":"Welch","sequence":"first","affiliation":[{"name":"New York City Department of Health and Mental Hygiene Queens  New York USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kimberly","family":"Caramanica","sequence":"additional","affiliation":[{"name":"New York City Department of Health and Mental Hygiene Queens  New York USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carey B.","family":"Maslow","sequence":"additional","affiliation":[{"name":"New York City Department of Health and Mental Hygiene Queens  New York USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert M.","family":"Brackbill","sequence":"additional","affiliation":[{"name":"New York City Department of Health and Mental Hygiene Queens  New York USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Steven D.","family":"Stellman","sequence":"additional","affiliation":[{"name":"New York City Department of Health and Mental Hygiene Queens  New York USA"},{"name":"Department of Epidemiology, Mailman School of Public Health Columbia University  New York New York USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark R.","family":"Farfel","sequence":"additional","affiliation":[{"name":"New York City Department of Health and Mental Hygiene Queens  New York USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,3,8]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.nmd.0000228503.95503.e9"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890423349"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.20982\/tqmp.05.1.p011"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/019394599701900303"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/0005-7967(96)00033-2"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1192\/bjp.bp.111.096552"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00127-009-0011-y"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2009.1121"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.4088\/JCP.10m06019gry"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1037\/a0018601"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/jts.20345"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11524-008-9317-4"},{"key":"e_1_2_5_14_1","doi-asserted-by":"publisher","DOI":"10.1097\/EDE.0b013e31815c1dbf"},{"key":"e_1_2_5_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.socscimed.2011.02.022"},{"key":"e_1_2_5_16_1","doi-asserted-by":"publisher","DOI":"10.1177\/0165025409343765"},{"key":"e_1_2_5_17_1","doi-asserted-by":"publisher","DOI":"10.1002\/jts.22011"},{"key":"e_1_2_5_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/sim.2806"},{"key":"e_1_2_5_19_1","doi-asserted-by":"publisher","DOI":"10.4159\/9780674041318"},{"key":"e_1_2_5_20_1","doi-asserted-by":"publisher","DOI":"10.2105\/AJPH.2012.300690"},{"key":"e_1_2_5_21_1","doi-asserted-by":"publisher","DOI":"10.1002\/jts.20544"},{"key":"e_1_2_5_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.socscimed.2009.03.043"},{"key":"e_1_2_5_23_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00127-014-0970-5"},{"key":"e_1_2_5_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(11)60967-7"},{"key":"e_1_2_5_25_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291713000597"},{"key":"e_1_2_5_26_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.janxdis.2011.07.004"},{"key":"e_1_2_5_27_1","doi-asserted-by":"publisher","DOI":"10.1002\/jts.21718"},{"key":"e_1_2_5_28_1","doi-asserted-by":"publisher","DOI":"10.1177\/0022146510395592"},{"key":"e_1_2_5_29_1","doi-asserted-by":"publisher","DOI":"10.1159\/000049343"},{"key":"e_1_2_5_30_1","unstructured":"Weathers F.W.
