However, few studies have used brain-based measures to identify imaging associations with illness severity at the level of individual patients. This study applied connectome-based predictive modeling (CPM), a recently developed data-driven and subject-level method, to identify brain function features that are related to symptom severity of trauma survivors. Resting-state fMRI scans and clinical ratings were obtained 10\u201315 months after the earthquake from 122 earthquake survivors. Symptom severity of post-traumatic stress disorder features for each survivor was evaluated using the Clinician Administered Post-traumatic Stress Disorder Scale (CAPS-IV). A functionally pre-defined atlas was applied to divide the human brain into 268 regions. Each individual\u2019s functional connectivity 268 \u00d7 268 matrix was created to reflect correlations of functional time series data across each pair of nodes. The relationship between CAPS-IV scores and brain functional connectivity was explored in a CPM linear model. Using a leave-one-out cross-validation (LOOCV) procedure, findings showed that the positive network model predicted the left-out individual\u2019s CAPS-IV scores from resting-state functional connectivity. CPM predicted CAPS-IV scores, as indicated by a significant correspondence between predicted and actual values (<jats:italic>r<\/jats:italic> = 0.30, <jats:italic>P<\/jats:italic> = 0.001) utilizing primarily functional connectivity between visual cortex, subcortical-cerebellum, limbic, and motor systems. The current study provides data-driven evidence regarding the functional brain features that predict symptom severity based on the organization of intrinsic brain networks and highlights its potential application in making clinical evaluation of symptom severity at the individual level.<\/jats:p>","DOI":"10.3389\/fnbeh.2020.563152","type":"journal-article","created":{"date-parts":[[2020,12,21]],"date-time":"2020-12-21T04:42:05Z","timestamp":1608525725000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":24,"title":["Individualized Prediction of PTSD Symptom Severity in Trauma Survivors From Whole-Brain Resting-State Functional Connectivity"],"prefix":"10.3389","volume":"14","author":[{"given":"Xueling","family":"Suo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Du","family":"Lei","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenbin","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lingjiang","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John A.","family":"Sweeney","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiyong","family":"Gong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2020,12,21]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"489","DOI":"10.1016\/j.neuroimage.2018.05.005","article-title":"Default mode network abnormalities in posttraumatic stress disorder: a novel network-restricted topology approach","volume":"176","author":"Akiki","year":"2018","journal-title":"NeuroImage"},{"key":"B2","volume-title":"Diagnostic and Statistical Manual of Mental Disorders.","year":"2013"},{"key":"B3","doi-asserted-by":"publisher","first-page":"281","DOI":"10.1590\/s1516-44462008000300016","article-title":"Cerebellum and psychiatric disorders","volume":"30","author":"Balda\u00e7ara","year":"2008","journal-title":"Braz.
