Traditionally, researchers sum PTSD symptoms such as intrusive thoughts, restricted affect, and memory impairment to create a total score, and then use this score to establish a threshold that differentiates traumatized participants from healthy controls. Researchers then investigate differences between these two groups for clinical variables like risk factors, treatment response, or biological markers. This routine practice presupposes that PTSD is a discrete condition, and that PTSD symptoms are roughly equally relevant to the disorder.
A recent alternative approach called Symptomics (Fried et al., 2015) has been proposed, which entails the investigation of individual psychopathological symptoms on the one hand, and the study of the causal dynamics of these symptoms in psychopathological networks on the other. This novel framework is supported by a growing chorus of voices and has shown very promising findings in depression research: depression symptoms differentially relate to risk factors, impact on impairment, treatment response, and biological markers (Fried & Nesse, 2015), and depression symptoms seem to form networks of causal relations (van Borkulo et al., 2015). Arguably, these insights that may offer new avenues for prevention and intervention cannot be gained when analyzing sums of symptoms.
The symptomics framework has only recently been applied to PTSD (Mcnally et al., 2014). The present special issue PTSD Symptomics: Analyzing individual PTSD symptoms and their network configurations in traumatized populations invites symptom-based papers for the domain of PTSD research to explore to which degree PTSD symptoms differ from each other in important aspects, and to establish the ways in which PTSD symptoms interact with each other in networks.
The European Journal of Psychotraumatology invites original research papers utilizing multivariate symptom-based analysis (e.g., Jokela, Virtanen, & Batty, 2016) or network analysis (e.g., van Borkulo et al., 2015), as well as short communications and debate pieces on the following topics:
- PTSD symptom networks, either on the level of groups or individuals, in cross-sectional or time-series data
- The stability of PTSD symptomatology and PTSD networks over time
- PTSD comorbidity research from a network perspective
- Symptom-based analyses that investigate whether PTSD symptoms are differentially related to various clinically relevant variables such as impairment, risk factors, biomarkers, etc.
- Systematic reviews focusing on PTSD symptomics
