To explore predictors of a chronic and delayed trajectory of posttraumatic stress symptoms (PTSS) after a natural disaster, we analyzed psychometric data collected from 412 residents of Christchurch, New Zealand after a 6.3 magnitude earthquake struck in February 2011. Participants from suburbs with different levels of socioeconomic status (SES) and earthquake impact completed a door\u2010to\u2010door survey 4\u20137 months after the earthquake (Time 1; <jats:italic>N<\/jats:italic> = 600) and again 10\u201311 months after the earthquake (Time 2; <jats:italic>N<\/jats:italic> = 412). The survey included the Acute Stress Disorder Scale, the Patient Health Questionnaire's nine\u2010item Depression subscale, and the Generalized Anxiety Disorder\u20137 scale, along with single\u2010item measures of variables including aftershock anxiety and family tension. Hobfoll's conservation of resources theory was used to guide data interpretation. High levels of depression, odds ratio (<jats:italic>OR<\/jats:italic>) = 1.24, and anxiety, <jats:italic>OR<\/jats:italic> = 1.24, at Time 1 significantly predicted membership in the <jats:italic>chronic<\/jats:italic> trajectory. Predictors of a delayed onset of symptoms included increased aftershock anxiety, <jats:italic>OR<\/jats:italic> = 1.29, and family tension, <jats:italic>OR<\/jats:italic> = 1.35, over time, as well as living in an area defined as being of low, <jats:italic>OR =<\/jats:italic> 5.36, or medium, <jats:italic>OR<\/jats:italic> = 11.39, SES. Results highlight risk factors for elevated PTSS and resources that individuals can use to offset threatened loss. These findings have implications for service providers, agencies, and the public.<\/jats:p>","DOI":"10.1002\/jts.22387","type":"journal-article","created":{"date-parts":[[2019,3,25]],"date-time":"2019-03-25T16:39:27Z","timestamp":1553531967000},"page":"206-214","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Predictors of Posttraumatic Stress Symptom Trajectories Following the Fatal 2011 Christchurch, New Zealand Earthquake"],"prefix":"10.1002","volume":"32","author":[{"given":"Hannah","family":"Jones","sequence":"first","affiliation":[{"name":"Department of Psychology University of Canterbury  Christchurch New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin J.","family":"Dorahy","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Canterbury  Christchurch New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eileen","family":"Britt","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Canterbury  Christchurch New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy","family":"Rowlands","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Canterbury  Christchurch New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charlotte","family":"Renouf","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Canterbury  Christchurch New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janet D.","family":"Carter","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Canterbury  Christchurch New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donncha","family":"Hanna","sequence":"additional","affiliation":[{"name":"School of Psychology The Queen's University of Belfast  Belfast Northern Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,3,25]]},"reference":[{"key":"e_1_2_5_2_1","volume-title":"Diagnostic and statistical manual of mental disorders","author":"American Psychiatric Association","year":"1994"},{"key":"e_1_2_5_3_1","volume-title":"Health, stress, and coping","author":"Antonovsky A.","year":"1979"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chiabu.2017.09.007"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1037\/0003-066X.59.1.20"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1037\/0022-006X.75.5.671"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1037\/a0017829"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1037\/0022-3514.88.6.984"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1037\/1040-3590.12.1.61"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1037\/0021-843X.105.4.617"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1037\/0033-2909.98.2.310"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00890095"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/bjop.12097"},{"key":"e_1_2_5_14_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291715000884"},{"key":"e_1_2_5_15_1","doi-asserted-by":"publisher","DOI":"10.1192\/bjp.174.4.353"},{"key":"e_1_2_5_16_1","doi-asserted-by":"publisher","DOI":"10.1093\/epirev\/mxi003"},{"key":"e_1_2_5_17_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11606-007-0333-y"},{"key":"e_1_2_5_18_1","unstructured":"Gruene T.(2017).Vulnerability and resilience to stressful and traumatic events: Stressor controllability sex differences and individual differences.
