A latent profile analysis of PTSD symptoms among UK treatment seeking veterans

Examining the Role of Posttraumatic Stress and Depressive Symptoms in HIV Pre-exposure Prophylaxis (PrEP) Motivation Among Women Survivors of Intimate Partner Violence

Post-traumatic stress disorder (PTSD) and major depressive disorder (MDD) are associated with functional impairments, yet little is known about their influence on HIV pre-exposure prophylaxis (PrEP) motivation among women survivors of intimate partner violence (IPV). Understanding how PTSD and MDD symptoms influence PrEP motivation is particularly important given survivors of IPV have an increased risk for HIV acquisition. The present study assessed the association between PrEP motivation with latent profiles of PTSD and MDD symptoms among women survivors of IPV. Data were collected from a sample of 285 women from Baltimore, MD, and New Haven, CT. Latent profile analysis (LPA) was performed to identify distinct patterns of depressive and PTSD symptoms among women survivors of IPV. Binary logistic regression was performed to examine the association of profile membership on PrEP motivation. A six-profile solution was determined to best fit the data. Profiles were characterized by: Profile 1, very low depressive and very low PTSD symptoms (28.07%); Profile 2, average depressive symptoms and low (below the mean) PTSD symptoms (21.05%); Profile 3, high depressive symptoms and low (below the mean) PTSD symptoms (9.8%); Profile 4, moderate depressive symptoms and high PTSD symptoms (15.78%); Profile 5, high PTSD avoidance and average depressive symptoms (17.1%); Profile 6, high depressive and high PTSD symptoms (8%). We found that, the odds of being in Stage 3 of the PrEP Motivational Cascade (PrEParation; defined by having access to a medical provider to prescribe PrEP, be willing to take PrEP, and self-identifying as an appropriate candidate for PrEP) compared to Stage 1 of the PrEP Motivational Cascade (Precontemplation; defined by being eligible for PrEP, but not willing to take PrEP and/or not self-identifying as an appropriate candidate for PrEP) were lower for women assigned to the low depressive symptoms and low PTSD symptoms profile (Profile 1 of the LPA) compared to women in the high depressive symptoms and High PTSD symptoms profile (Profile 6 of the LPA, OR = 0.22, 95% CI = 0.06-0.76, p = 0.02). Women assigned to the low PTSD symptoms and average depressive symptoms profile (Profile 2 of the LPA) had lower odds of being in Stage 3 (PrEParation) compared to Stage 1 (Precontemplation) compared to women assigned to the high depressive symptoms and High PTSD symptoms profile (Profile 6 of the LPA, OR = 0.25, 95% CI = 0.07-0.92, p = 0.037). Women survivors of IPV with higher PTSD and MDD symptoms expressed greater motivation to engage in PrEP compared to women survivors with low PTSD and low MDD symptoms. Findings support the CDC's clinical PrEP recommendations to integrate depression screening into PrEP services, but there is a critical need to also include PTSD screening. Further, MDD and PTSD symptoms may present differential barriers to PrEP motivation among women survivors of IPV. Precision care could synchronize trauma-informed practices and mental health treatment to engage survivors in PrEP services.

Latent profile analysis of transdiagnostic emotional distress, suicidality, and resilience in first responders

BACKGROUND

First responders (i.e., law enforcement officers, firefighters, and emergency medical technicians/paramedics), experience significantly higher occupational trauma exposure than U.S. adult workers outside these fields, leading to increased risks of comorbid mental health disorders. Repeated and intense trauma exposure may combine with personal factors to place them at higher risk for suicide. Conversely, first responders may show higher levels of psychological resilience in the face of occupational trauma experiences. Some research exists on resilience, though little is known about suicide resilience in first responder populations.

METHODS

We used latent profile analysis (LPA) on a treatment-seeking sample of first responders (N = 340) with measures of posttraumatic stress disorder (PTSD), generalized anxiety, depression, suicidality, and resilience.

RESULTS

We determined the best fit was a five-class solution, including the following emotional distress categories: minimal (19 %), mild (33 %), moderate (8 %), moderately severe (27 %), and severe (13 %) emotional distress. In this study, all multivariate analyses of variance (MANOVAs) were statistically significant and had large effect sizes ranging from the lowest (resilience) to the largest (depression).

LIMITATIONS

We used self-report assessments and not a clinical interview. Also, we did not have data on measures of substance use, emotional dysregulation (e.g., attachment), or trauma exposure.

CONCLUSIONS

This study underscores the critical need for developing and implementing transdiagnostic interventions that not only address the spectrum of emotional distress and suicidality but also actively enhance resilience among treatment-seeking first responders.

Using Passive and Active Data to Predict Post-Traumatic Stress Disorder Symptoms and Cannabis Use in Recently Discharged UK Veterans: A Protocol for the MAVERICK Feasibility Study

Introduction

Post-traumatic stress disorder (PTSD) and comorbid cannabis use disorder (CUD) is a growing concern amongst UK veterans. Co-occurrence of problematic cannabis use, and PTSD is associated with greater PTSD symptom severity, decreased likelihood of cannabis use cessation, worse clinical outcomes, and increased societal burden. Despite increased screening efforts among veterans, there are no effective strategies for predicting risk for PTSD and problematic drug use escalation before these conditions develop, worsen, or become chronic.

Methods

This feasibility study employs a 4-week (28 day) longitudinal design (daily data collection), multiple passive data collection features via a bespoke study smartphone app called MAVERICK, and active data collection via wearable technology to predict clinically meaningful escalations in cannabis use and PTSD symptoms in UK veterans. Questionnaire data will be collected between 06:00 and 10:00 each day. Passive data will be collected continuously in the background.

Results

The study will begin recruitment in June 2023 and will require 18 months to complete. Study results are expected to be published in January 2024.

Discussion

This trial will provide information on the feasibility and utility of a smartphone app (MAVERICK) to collect both active and passive data to predict PTSD symptoms and cannabis use in a UK veteran population. If the smartphone app is deemed feasible and acceptable to users, it has the potential to provide an effective measurement tool to mitigate risk of PTSD and problematic cannabis use among veterans.

Heterogeneity of emotional distress in pregnancy during COVID-19 pandemic: a latent profile analysis

BACKGROUND

Emotional distress, including depressive and anxiety symptoms, is a common concern among pregnant individuals and has negative impacts on maternal and offspring's health. Previous studies indicated the heterogeneity of perinatal emotional distress. Moreover, during the pandemic of COVID-19, expectant mothers are faced with more tough challenges, which could exacerbate their emotional distress.

OBJECTIVE

The aim of present study is to examine potential subgroups with distinct profiles on emotional distress and relationship resources during the pandemic.

METHODS

A total of 187 pregnant people in China were recruited from April 22 to May 16 in 2020. Latent profile analysis was applied based on prenatal depressive and anxiety symptoms, COVID-19-related negative emotions, prenatal attachment, marital satisfaction and family sense of coherence.

RESULTS

Four subgroups were identified. Group 1 and Group 2 shared with low levels of emotional distress and COVID-19-related negative emotions, among which Group 1 had plenty of relationship resources, while Group 2 had insufficient support. Group 3 had moderate levels of emotional distress but above-average prenatal attachment. Group 4 was a highly distressed subtype with severe emotional distress and poor states across all domains.

CONCLUSION

Our findings support that emotion distress among expecting mothers is heterogeneous, highlighting the need for tailed interventions to address the specific needs of subgroups during pregnancy.

Identifying post-traumatic stress symptom typologies in clinical and non-clinical healthcare staff: a latent profile analysis

Background: There has been growing concern regarding increasing levels of post-traumatic stress (PTS) symptoms experienced by healthcare workers (HCW) in the UK, particularly following the COVID-19 pandemic.Objectives: PTS symptom typologies have been investigated in other adult populations using person-centred latent variable approaches, revealing profiles showing differing symptom levels and patterns. We aimed to explore typologies among clinical and non-clinical healthcare staff to elucidate heterogeneity of presentation.  Methods: This was a retrospective study using referral data from treatment-seeking healthcare staff in the North of England (N = 1600). We employed latent profile analysis using the PTSD International Trauma Questionnaire domains as profile indicators. We included covariates relating to role-type, depression, anxiety and mental health concerns before March of 2020.   Results: A model with six profiles fit the data best. Profile names were given as follows: 'No symptom'; 'Low symptom'; 'Low symptom (moderate Sense of current threat (Th_dx) and Functional impairment (FI))'; 'Moderate symptom (low Th_dx and high Avoidance (Av_dx))'; 'Moderate symptom'; and 'High symptom'. Covariates were shown to have differential predictive power on profile membership. Conclusions: The finding of profiles with pattern differences suggests a need for both differential and specifically targeted treatments, as well as a consideration of early intervention for those individuals with subclinical PTS symptoms. As expected, anxiety and depression were both predictors of several of the symptomatic profiles, with anxiety producing a larger effect. Further research is required to fully understand the link between role-type and PTS symptom typologies among HCW. .

Exploring heterogeneity in PTSD symptoms and associated predictors and outcomes in Afghanistan veterans: A latent profile analysis

Research on posttraumatic stress symptoms (PTSS) typically focuses on diagnosis or symptom severity, however, this overlooks the variety of symptom patterns that exist. Latent profile analysis was used to explore PTSS profiles in a sample of Norwegian Afghanistan veterans (n = 4052, 91.7% males). Multinomial logistic regression analyses were conducted to examine predictors and outcomes associated with PTSS profile membership. Three profiles emerged: Low Symptoms profile (85%); High Numbing and Arousal profile (13%); and High Symptoms profile (2%). Being female, lower number of deployments, barriers to disclose war-related experiences, and higher number of potentially morally injurious events (PMIEs) were associated with belonging to the High Symptoms profile compared to the High Numbing and Arousal (Male gender: OR = 0.37, p < .05; Number of deployments: OR = 0.68, p < .05; Barriers to disclose: OR = 1.39, p < .001; PMIEs: OR = 1.15. p < .05), or Low Symptoms profile (Male gender: OR = 0.36, p < .05; Number of deployments: OR = 0.67, p < .01; Barriers to disclose: OR = 1.80, p < .001; PMIEs: OR = 1.32. p < .001). Participants in the High Symptoms profile had the highest probability of mental health service use (0.37) and endorsing suicidal ideation (0.38), compared to the two other profiles (p < .01). Participants in the High Numbing and Arousal profile had a higher probability of seeking professional mental health care (0.17), endorsing suicidal ideation (0.16), and reporting more suicide attempts compared to the Low Symptom profile (0.02 vs. 0.00, p < .001). These findings highlight the importance of considering the heterogeneity of PTSS profiles and understanding the predictors and responses of individuals who exhibit elevated PTSS symptoms.

Dyadic Investigation of Posttraumatic Stress Symptoms and Daily Sleep Health in Patients With Cancer and Their Caregivers

OBJECTIVE

Cancer can be a traumatic experience affecting multidimensional aspects of sleep among patients and caregivers. This study examined the differential associations of cancer-related posttraumatic stress symptoms (PTSS) with various sleep markers in this population.

METHODS

Patients newly diagnosed with colorectal cancer ( n = 138, mean age = 56.93 years, 31.88% female, 60.14% Hispanic, 6.53 months after diagnosis) and their sleep-partner caregivers ( n = 138, mean age = 55.32 years, 68.12% female, 57.97% Hispanic) completed questionnaires assessing the four PTSS clusters (intrusion, avoidance, alterations in arousal and reactivity, negative alterations in cognitions and mood). Participants also completed daily sleep diaries for 14 consecutive days, from which sleep onset latency (SOL), wake after sleep onset (WASO), and sleep duration were derived.

RESULTS

Actor-partner interdependence model revealed that caregivers' greater alterations in arousal and reactivity were associated with their own longer SOL ( b = 15.59, p < .001) and their patients' longer sleep duration ( b = 0.61, p = .014), whereas patients' arousal and reactivity were associated with their caregivers' shorter SOL ( b = -8.47, p = .050). Patients' and caregivers' greater negative alterations in cognitions and mood were associated with patients' longer SOL ( b = 9.15, p = .014) and shorter sleep duration ( b = -0.41, p = .050), respectively. Caregivers' greater intrusion was related to their own shorter SOL ( b = -10.14, p = .004).

CONCLUSIONS

The four PTSS clusters, particularly arousal and reactivity and negative cognitions and mood, have distinct associations with sleep markers individually and dyadically in patients and caregivers affected by cancer. Investigations of psychosocial and biobehavioral pathways underlying these relations are warranted. Tailored trauma treatments and sleep interventions may improve the well-being of this population.

Flexible emotional regulation typology: associations with PTSD symptomology and trait resilience

BACKGROUND

Multiple factors influence posttraumatic stress disorder (PTSD) risk in trauma exposed individuals. An established association exists between trait resilience and decreased PTSD distress and between emotion regulation (ER) ability/flexibility and trait resilience. Typologies in ER ability/flexibility, associated with trait resilience and PTSD experience, could explain the difference in risk. This study aimed to explore the relationship between ER ability, ER flexibility, context sensitivity, resilience, and PTSD.

METHODS

Data from N = 563 trauma exposed UK residents was used in a latent profile analysis (LPA) and membership in the resultant profiles was explored in a logistic regression of sociodemographics, resilience, and PTSD symptomology.

RESULTS

Analysis showed 2 latent profiles (High Flexibility, Low Flexibility) typified by emotion regulation ability and context sensitivity. Members of the Low Flexibility profile were more likely to be younger, male, endorsing less trait resilience, and experiencing negative cognition/mood and hyperarousal PTSD symptomology.

CONCLUSIONS

Difficulties in ER ability and flexibility could be improved with targeted learning in a therapeutic or home setting, potentially increasing trait resilience after trauma exposure and reducing PTSD distress.

Latent emotion profiles of PTSD and specific emotions predicting differential therapy outcomes in a dismantling study of cognitive processing therapy

Posttraumatic stress disorder (PTSD) is theoretically maintained by avoidance of emotions elicited from trauma-related beliefs. Whether PTSD symptom profiles and specific emotions predict treatment response is unknown. This secondary data analysis examined: a) whether individuals with PTSD can be sub-classified based on symptom clusters and specific emotions, and b) if these subgroups predict differential responses to cognitive versus exposure-based PTSD interventions. Women with physical or sexual assault-related PTSD were randomized to CPT (cognitive processing therapy elements only), CPT with written accounts (CPT+A), or written accounts (WA) only (n = 150). Participants completed baseline measures of PTSD, state anxiety, internalized anger, externalized anger, shame, and guilt, and weekly PTSD measures during and 6 months after treatment. Latent profile analyses revealed four subgroups: low symptoms and emotions; moderate-high reexperiencing, low internalized emotions (i.e., moderate-high reexperiencing, moderate avoidance/hyperarousal/guilt, low shame/internalized anger/anxiety); low reexperiencing, moderate emotions (i.e., low re-experiencing, moderate avoidance/hyperarousal/guilt, moderate other emotions); and high symptoms and emotions (high symptoms and emotions except moderate externalized anger). The high symptom and emotion subgroup experienced greater PTSD symptom improvements in cognitive conditions than WA. Other groups did not exhibit differential change across conditions. Cognitive interventions may be well-suited for severe PTSD with high self-directed emotions. CLINICALTRIALS.GOV IDENTIFIER: NCT00245232.

Variation in health service use by veterans with an accepted disability of post-traumatic stress disorder who had a service record post 1975: a cluster analysis

Background

The use of health services is likely to vary among veterans with an accepted disability of post-traumatic stress disorder (PTSD), however, the extent of variation is not known. We aimed to determine the extent and type of health services used by veterans with an accepted disability of PTSD.

Methods

The cohort included veterans who served post 1975, were eligible for all Australian Government Department of Veterans’ Affairs funded health services, had PTSD as an accepted disability prior to July 2015 and were alive at the 30 June 2016. Veterans were assigned to groups based on their use of health services using K-means cluster analysis.

Results

The cohort comprised five clusters involving 2286 veterans. The largest cluster (43%) were a younger, general practitioner (GP) managed cluster who saw their GP quarterly and the psychiatrist twice a year. The second GP cluster (30%) had higher levels of physical comorbidity. The psychiatrist managed cluster (14%) had a mean of 12 psychiatrist visits and one PTSD hospitalisation in the year. The remaining two clusters involved GP and allied healthcare, but no psychologist care. High levels of antidepressant use occurred in all clusters, ranging from 44% up to 69%. The psychiatrist managed cluster had 47% on antipsychotics and 58% on anxiolytics.

Conclusion

Our study highlights the heterogeneity in health service use. These results identify the significant health utilisation required for up to one-sixth of veterans with PTSD and the significant role of primary care physicians in supporting veterans with PTSD.

Making the transition: How finding a good job is a risky business for military Veterans in Northern Ireland

Veterans transitioning from the military to civilian life may encounter difficulties in different domains of functioning. Most research in this area comes from the US and Israel, with Veterans in Northern Ireland (NI) in the United Kingdom, remaining an understudied population. This qualitative study aimed to examine the nature of transition experiences of NI Veterans by analyzing responses (N = 252) to an open-ended question related to the transition process, in a self-report survey. Thematic analysis highlighted both positive and negative experiences across high-level themes. These were related to (1a) how good the military life had been, (1b) the transition had been easy for some Veterans, and (1c) the skills gained in the military have been valuable; (2) it was hard to adjust to civilian life/still adjusting; (3) negative employment experiences; (4) lack of trust; (5) transitioning is hard in NI; and (6) inadequate support, post-service. The findings highlight that NI Veterans share some of the same challenges as other Veterans; however, the challenges in NI are compounded by ongoing security concerns and political tensions, which means living under the radar is a reality for many, making finding meaningful work and community integration difficult. The findings indicate that preparation for civilian life and the acculturation process needs to start many months before discharge. Perhaps more crucially, regiments should work closely with and support civilian employers to equip them to recognize and value the skills ex-Services Veterans can offer, and find a good fit for their skills within their organizations.

Social engagement, self-efficacy, and posttraumatic stress symptoms across 6 months of psychotherapy

OBJECTIVE

The current study was conducted in a naturalistic treatment setting to examine whether and how perceptions about social engagement, trauma coping self-efficacy, and posttraumatic stress symptoms (PTS) influence one another across 6 months of psychotherapy for trauma survivors.

METHOD

The sample included 183 clients who reported exposure to traumatic events and significant PTS (PCL-5 ≥ 33). Participants (M_age  = 37.8, 53.6% female) completed surveys at intake, 3 months, and 6 months into treatment. A cross-lagged panel analysis was used to test the relationships among perceived social engagement, coping self-efficacy, and PTS across three assessment points.

RESULTS

PTS at 3-months was a mediator in the relationship between intake perceived social engagement and 6-month coping self-efficacy and between intake perceived social engagement and 6-month perceived social engagement.

CONCLUSIONS

PTS several months into treatment may serve as a mechanism between intake perceived social engagement and functional outcomes such as coping self-efficacy.

Psychological therapies for post-traumatic stress disorder in adults: systematic review and meta-analysis

Background: Psychological therapies are the recommended first-line treatment for post-traumatic stress disorder (PTSD). Previous systematic reviews have grouped theoretically similar interventions to determine differences between broadly distinct approaches. Consequently, we know little regarding the relative efficacy of the specific manualized therapies commonly applied to the treatment of PTSD. Objective: To determine the effect sizes of manualized therapies for PTSD. Methods: We undertook a systematic review following Cochrane Collaboration guidelines. A pre-determined definition of clinical importance was applied to the results and the quality of evidence was appraised using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. Results: 114 randomized-controlled trials (RCTs) of 8171 participants were included. There was robust evidence that the therapies broadly defined as CBT with a trauma focus (CBT-T), as well as Eye Movement Desensitization and Reprocessing (EMDR), had a clinically important effect. The manualized CBT-Ts with the strongest evidence of effect were Cognitive Processing Therapy (CPT); Cognitive Therapy (CT); and Prolonged Exposure (PE). There was also some evidence supporting CBT without a trauma focus; group CBT with a trauma focus; guided internet-based CBT; and Present Centred Therapy (PCT). There was emerging evidence for a number of other therapies. Conclusions: A recent increase in RCTs of psychological therapies for PTSD, results in a more confident recommendation of CBT-T and EMDR as the first-line treatments. Among the CBT-Ts considered by the review CPT, CT and PE should be the treatments of choice. The findings should guide evidence informed shared decision-making between patient and clinician.
