Understanding PTSD Symptoms Over Time: Longitudinal Network Analysis

Background
Network modeling has been applied in a range of trauma-exposed samples, yet results are limited by an over reliance on cross-sectional data. The current analyses used posttraumatic stress disorder (PTSD) symptom data collected over a 5-year period to estimate a more robust between-subject network and an associated symptom change network.

Methods
A PTSD symptom network is measured in a sample of military veterans across four time points (Ns = 1254, 1231, 1106, 925). The repeated measures permit isolating between-subject associations by limiting the effects of within-subject variability. The result is a highly reliable PTSD symptom network. A symptom slope network depicting covariation of symptom change over time is also estimated.

Results
Negative trauma-related emotions had particularly strong associations with the network. Trauma-related amnesia, sleep disturbance, and self-destructive behavior had weaker overall associations with other PTSD symptoms.

Conclusions
PTSD’s network structure appears stable over time. There is no single ‘most important’ node or node cluster. The relevance of self-destructive behavior, sleep disturbance, and trauma-related amnesia to the PTSD construct may deserve additional consideration.

Posttrauma Anxiety and Depression Explained by Previous Trauma – Racial and Ethnic Differences Identified

Background
Racial and ethnic groups in the USA differ in the prevalence of posttraumatic stress disorder (PTSD). Recent research however has not observed consistent racial/ethnic differences in posttraumatic stress in the early aftermath of trauma, suggesting that such differences in chronic PTSD rates may be related to differences in recovery over time.

Methods
As part of the multisite, longitudinal AURORA study, we investigated racial/ethnic differences in PTSD and related outcomes within 3 months after trauma. Participants (n = 930) were recruited from emergency departments across the USA and provided periodic (2 weeks, 8 weeks, and 3 months after trauma) self-report assessments of PTSD, depression, dissociation, anxiety, and resilience. Linear models were completed to investigate racial/ethnic differences in posttraumatic dysfunction with subsequent follow-up models assessing potential effects of prior life stressors.

Results
Racial/ethnic groups did not differ in symptoms over time; however, Black participants showed reduced posttraumatic depression and anxiety symptoms overall compared to Hispanic participants and White participants. Racial/ethnic differences were not attenuated after accounting for differences in sociodemographic factors. However, racial/ethnic differences in depression and anxiety were no longer significant after accounting for greater prior trauma exposure and childhood emotional abuse in White participants.

Conclusions
The present findings suggest prior differences in previous trauma exposure partially mediate the observed racial/ethnic differences in posttraumatic depression and anxiety symptoms following a recent trauma. Our findings further demonstrate that racial/ethnic groups show similar rates of symptom recovery over time. Future work utilizing longer time-scale data is needed to elucidate potential racial/ethnic differences in long-term symptom trajectories.

Associations Between Existential Concerns and Adverse Experiences: A Systematic Review

Journal of Humanistic Psychology, Ahead of Print. Exposure to traumatic events or adverse experiences and its consequences have been studied mainly from a posttraumatic stress disorder perspective. Existential psychotherapy focuses on universal human concerns and the anxiety that occurs when a person confronts the conflicts inherent in life and toward death, which include the experience of difficult situations. A systematic review was performed including 56 papers that studied the relations between adverse experiences and existential concerns. The articles were assessed and described in relation to existential domains, type of adverse experience, posttraumatic responses, and existential psychological interventions. Existential concerns appeared in different degrees and categories in studied samples. Outcomes suggest that from an existential psychotherapy perspective, reactions to traumatic events can be both negative and positive for a person. In addition, the pass of time turned out to be an important factor, especially in finding meaning from traumatic experiences, the reduction of negative symptoms, and the achieving of posttraumatic growth. Existential-related interventions described in this review showed positive outcomes, suggesting that it is an effective trauma treatment approach.
