However, a minority of individuals may instead experience a self\u2010determination violation as a result of their self\u2010regulatory capacity being overwhelmed. This self\u2010determination violation is marked by chaotic and shifting adjustment, maladaptive regulation attempts, and, ultimately, a shift to an impaired self\u2010state and the development of persistent psychopathology, such as posttraumatic stress disorder (PTSD). The current study utilized nonlinear dynamic system (NDS) analysis to identify adjustment trajectory dynamics among rural hurricane survivors in North Carolina (<jats:italic>N<\/jats:italic> = 131) who completed daily ecological momentary assessments (EMAs) regarding their distress (i.e., negative mood and PTSD symptoms), regulation efforts (e.g., coping), and appraisals (e.g., coping self\u2010efficacy) over a 6\u2010week period. Four adjustment trajectories were identified, including two largely adaptive trajectories (69.0% and 5.7%), a less stable adjustment trajectory (6.9%), and a fourth trajectory (18.4%) marked by shifting adjustment states and more frequent maladaptive regulation and negative appraisals, suggesting possible self\u2010determination violation. Consistent with this possibility, this final trajectory was also associated with more severe PTSD symptoms relative to the other three trajectories at enrollment and 6\u2010month follow\u2010up. Future work should utilize NDS to model posttrauma adjustment dynamics from within a SRST framework to identify patterns of positive and negative adjustment dynamics at different time points in the trauma recovery process.<\/jats:p>","DOI":"10.1002\/jts.22926","type":"journal-article","created":{"date-parts":[[2023,3,30]],"date-time":"2023-03-30T15:04:44Z","timestamp":1680188684000},"page":"579-592","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Recovery and adjustment trajectories among Hurricane Florence survivors: Analysis utilizing nonlinear dynamic system modeling"],"prefix":"10.1002","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7067-1120","authenticated-orcid":false,"given":"Heather","family":"Littleton","sequence":"first","affiliation":[{"name":"University of Colorado Colorado Springs, Lyda Hill Institute for Human Resilience  Colorado Springs Colorado USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernard","family":"Ricca","sequence":"additional","affiliation":[{"name":"University of Colorado Colorado Springs, Lyda Hill Institute for Human Resilience  Colorado Springs Colorado USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ashley Batts","family":"Allen","sequence":"additional","affiliation":[{"name":"Department of Psychology University of North Carolina at Pembroke  Pembroke North Carolina USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charles","family":"Benight","sequence":"additional","affiliation":[{"name":"University of Colorado Colorado Springs, Lyda Hill Institute for Human Resilience  Colorado Springs Colorado USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,3,30]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"crossref","unstructured":"American Psychiatric Association.
