GLASSO-regularized partial correlation networks for CAPS-5 and PCL-5 items. Nodes are coded by color to correspond to the network community membership as identified by the spin glass algorithm. Positive edges appear in purple and negative edges in red, and node placement within the network was determined using the average layout between the CAPS-5 and PCL-5 networks. Network edges with a weight of .05 or higher are presented for ease of interpretation. Edge weights are scaled equally across the two networks (maximum = 1.0, cutoff = 0). To aid visual interpretation, the thickness of edges in the networks reflect the relative strength of the edge weight. CAPS-5 = Clinician Administered PTSD Scale for DSM–5; PCL-5 = PTSD Checklist for DSM–5; amn = amnesia; anh = loss of interest; avm = avoidance of memories, thoughts, and feelings; avx = avoidance of external reminders; blf = distorted negative beliefs; blm = distorted blame; cnc = concentration problems; det = detachment; drm = nightmares; fls = flashbacks; hyp = hypervigilance; irr = irritable or angry behavior; mem = intrusive memories; neg = persistent negative emotions; phy = physiological reactions to reminders; num = inability to experience positive emotions; rsk = reckless or self-destructive behavior; slp = sleep disturbance; str = exaggerated startle; ups = psychological distress in response to reminders.
