An explainable predictive model for anxiety symptoms risk among Chinese older adults with abdominal obesity using a machine learning and SHapley Additive exPlanations approach

Background

Early detection of anxiety symptoms can support early intervention and may help reduce the burden of disease in later life in the elderly with abdominal obesity, thereby increasing the chances of healthy aging. The objective of this research is to formulate and validate a predictive model that forecasts the probability of developing anxiety symptoms in elderly Chinese individuals with abdominal obesity.

Method

This research's model development and internal validation encompassed 2,427 participants from the 2017-2018 Study of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Forty-six variables were defined based on the Health Ecology Model (HEM) theoretical framework. Key variables were screened using LASSO regression, and the XGBoost (Extreme Gradient Boosting) model was further introduced to forecast the risk of developing anxiety symptoms in the elderly with abdominal obesity. SHapley Additive exPlanations (SHAP) was adopted to further interpret and show how the eigenvalues contributed to the model predictions.

Results

A total of 240 participants (9.89%) with anxiety symptoms out of 2,427 participants were included. LASSO regression identified nine key variables: looking on the bright side, self-reported economic status, self-reported quality of life, self-reported health status, watching TV or listening to the radio, feeling energetic, feeling ashamed/regretful/guilty, feeling angry, and fresh fruits. All the evaluation indicators of the XGBoost model showed good predictive efficacy. Based on the significance of the features identified by SHAP (Model Interpretation Methodology), the feature 'looking on the bright side' was the most important, and the feature 'self-reported quality of life' was the least important. The SHAP beeswarm plot illustrated the impacts of features affected by XGBoost.

Conclusion

Utilizing machine learning techniques, our predictive model can precisely evaluate the risk of anxiety symptoms among elderly individuals with abdominal obesity, facilitating the timely adoption of targeted intervention measures. The integration of XGBoost and SHAP offers transparent interpretations for customized risk forecasts.

Effectiveness of In-Theater Mental Health Assessments

INTRODUCTION

The leading cause for medical evacuation from the U.S. Central Command area of responsibility is because of mental health conditions. The In-Theater Mental Health Assessment (ITMHA) is a DoD-required screening of deployed personnel. It is vital to examine the efficacy of ITMHA's potential to significantly impact the mental health outcomes of service members.

MATERIALS AND METHODS

All ITMHA results of individuals in 2 deployed Army battalions along with a brigade headquarters deployed to U.S. Central Command between October 2022 and October 2023 were collected and analyzed. Descriptive statistics were used to characterize the results of the ITMHA.

RESULTS

Of 670 deployed service members, 157 (23%) scored positive on ITMHA. Ten service members were referred for additional mental health evaluation. The remaining 147 (22%) service members who scored positive were not referred because of a lack of significant impairment or were already engaged in mental health services. One service member in the study was evacuated because of a mental health condition. The most common major life stressors identified were family/relationship issues, sleep problems, and mental health concerns.

CONCLUSIONS

The number of deployed personnel identified through the ITMHA as requiring mental health care was modest. The ITMHA has multiple limitations that, if addressed, will improve its utility to mitigate mental health decline in the expeditionary environment.

Long-lasting effects of post-traumatic stress disorder in Yazidi women living in Northern Iraqi camps

The severity of post-traumatic stress disorder and its long-lasting effects among the Yazidi population has not yet been investigated.

Objectives

This study evaluated the impact of PTSD severity and chronicity on physiological and anthropometric parameters in women survivors of the genocide-related events after the so-called Islamic State of Iraq and Syria (ISIS) attack in 2014.

Methods

The diagnosis PTSD was assessed using PTSD Checklist for DSM-5 (PCL-5). Participants were divided into: External control (healthy individuals living outside the camps), Internal control (healthy individuals living in the camps), and PTSD group (individuals diagnosed with PTSD). The PTSD group was subdivided according to chronicity <2 years, 2-5 years, and >5 years and subdivided according to PTSD severity into "Moderate", "Severe" and "Extreme". Systolic blood pressure (SBP), diastolic blood pressure (DBP), blood oxygen saturation (SPO2) and heart rate (HR) were evaluated. Weight, height and waist circumference were measured. Body mass index (BMI) and waist-to-height ratio (WHtR) were calculated.

Results

The PTSD group showed significant increases in SBP, DBP, heart rate, BMI, WC, weight, and WHtR compared to the control groups. SPO2 values decreased in the PTSD group. As the disease progressed, there were further increases in SBP, DBP, heart rate, BMI, WC, WHtR, and weight. Similar increases were observed with the severity of the disease.

Conclusion

Our data indicates that a long-term impact on physiological and anthropometric parameters is present in women diagnosed with PTSD which might be aggravated by the severity and chronicity of the disease.

Post-traumatic Stress Disorder in Veterans: A Concept Analysis

Post-traumatic stress disorder (PTSD) occurs when an individual experiences a traumatic event that exceeds the limits of psychological endurance. Many veterans experience PTSD. PTSD can negatively impact veterans' quality of life, functioning, life satisfaction, and overall well-being. It is important to analyze the concept of PTSD in the veteran population. This concept analysis aimed to investigate the defining attributes, a model case, antecedents, consequences, and empirical referents related to the concept of PTSD among veterans. Walker and Avant's method was used to guide this concept analysis of PTSD. The results showed that three attributes were determined from the analysis: intrusive memories of traumatic events, feelings of isolation and estrangement, and negative cognitions. PTSD is conceptualized as a collection of symptoms that arise from highly traumatic experiences. The military environment predisposes veterans to traumatic events that should be identified or acknowledged. A better understanding of the concept of PTSD can facilitate the development of effective interventions for the veteran population and enhance their mental health.

Posttraumatic stress disorder, Veterans Health Administration use, and care-seeking among recent-era U.S. veterans

The current study investigated the associations among probable posttraumatic stress disorder (PTSD), recent Veterans Health Administration (VHA) health care use, and care-seeking for PTSD in U.S. military veterans. Analyses were conducted among 19,691 active duty military personnel enrolled in the Millennium Cohort Study who separated from the military between 2000 and 2012 and were weighted to the 1,130,103 active duty personnel who separated across this time period. VHA utilization was identified from electronic medical records in the year before survey completion, and PTSD care-seeking and PTSD symptoms were assessed through self-report on the 2014-2016 survey; thus, the observation period regarding care-seeking and VHA use encompassed 2013-2016. Veterans with probable PTSD were more likely to use VHA services than those without probable PTSD, aOR = 1.12, 95% CI [1.01, 1.24], although the strongest association with recent VHA use was a depression diagnosis, aOR = 2.47, 95% CI [2.26, 2.70]. Among veterans with probable PTSD, the strongest predictor of care-seeking was recent VHA use compared to community care, aOR = 4.01, 95% CI [3.40, 4.74); reporting a diagnosis of depression was the second strongest predictor of PTSD care-seeking, OR = 2.99, 95% CI [2.53, 3.54]. However, the absolute number of veterans with probable PTSD who were not seeking care was approximately equivalent between veterans using VHA services and those not using VHA services. Additionally, certain groups were identified as being at risk of not seeking care, namely Air Force veterans and veterans with high physical and mental functioning despite substantial PTSD symptoms.

Toward personalized care for insomnia in the US Army: a machine learning model to predict response to cognitive behavioral therapy for insomnia

STUDY OBJECTIVES

The standard of care for military personnel with insomnia is cognitive behavioral therapy for insomnia (CBT-I). However, only a minority seeking insomnia treatment receive CBT-I, and little reliable guidance exists to identify those most likely to respond. As a step toward personalized care, we present results of a machine learning (ML) model to predict CBT-I response.

METHODS

Administrative data were examined for n = 1,449 nondeployed US Army soldiers treated for insomnia with CBT-I who had moderate-severe baseline Insomnia Severity Index (ISI) scores and completed 1 or more follow-up ISIs 6-12 weeks after baseline. An ensemble ML model was developed in a 70% training sample to predict clinically significant ISI improvement (reduction of at least 2 standard deviations on the baseline ISI distribution). Predictors included a wide range of military administrative and baseline clinical variables. Model accuracy was evaluated in the remaining 30% test sample.

RESULTS

19.8% of patients had clinically significant ISI improvement. Model area under the receiver operating characteristic curve (standard error) was 0.60 (0.03). The 20% of test-sample patients with the highest probabilities of improvement were twice as likely to have clinically significant improvement compared with the remaining 80% (36.5% vs 15.7%; χ21 = 9.2, P = .002). Nearly 85% of prediction accuracy was due to 10 variables, the most important of which were baseline insomnia severity and baseline suicidal ideation.

CONCLUSIONS

Pending replication, the model could be used as part of a patient-centered decision-making process for insomnia treatment. Parallel models will be needed for alternative treatments before such a system is of optimal value.

Stepped collaborative care versus American College of Surgeons Committee on Trauma required screening and referral for posttraumatic stress disorder: Clinical trial protocol

BACKGROUND

Each year in the US, approximately 1.5-2.5 million individuals are so severely injured that they require inpatient hospital admissions. The American College of Surgeons Committee on Trauma (College) now requires that trauma centers have in place protocols to identify and refer hospitalized patients at risk injury psychological sequelae. Literature review revealed no investigations that have identified optimal screening, intervention, and referral procedures in the wake of the College requirement.

METHODS

The single-site pragmatic trial investigation will individually randomize 424 patients (212 intervention and 212 control) to a brief stepped care intervention versus College required mental health screening and referral control conditions. Blinded follow-up interviews at 1-, 3-, 6-, and 12-months post-injury will assess the symptoms of PTSD and related comorbidity for all patients. The emergency department information exchange (EDIE) will be used to capture population-level automated emergency department and inpatient utilization data for the intent-to-treat sample. The investigation aims to test the primary hypotheses that intervention patients will demonstrate significant reductions in PTSD symptoms and emergency department/inpatient utilization when compared to control patients. The study incorporates a Rapid Assessment Procedure-Informed Clinical Ethnography (RAPICE) implementation process assessment.

CONCLUSIONS

The overarching goal of the investigation is to advance the sustainable delivery of high-quality trauma center mental health screening, intervention, and referral procedures for diverse injury survivors. An end-of-study policy summit will harness pragmatic trial data to inform the capacity for US trauma centers to implement high-quality acute care mental health screening, intervention and referral services for diverse injured patient populations.

Post-traumatic stress disorder symptoms and PrEP intentions among Black American young adults at high-risk for HIV

OBJECTIVES

Black Americans bear the greatest burden of HIV, accounting for 43% of new diagnoses. Yet Black Americans also evidence the lowest utilization rates of Pre-Exposure Prophylaxis (PrEP), a highly effective biomedical strategy for preventing HIV infection. Predictors of PrEP acceptance vary; however, little is known about psychological distress, such as post-traumatic stress disorder (PTSD) symptoms, as a predictor.

DESIGN

In this cross-sectional study, n = 195 Black Americans, evidencing behaviors found in the research literature to heighten risk for contracting HIV (e.g. sex work, injection drug use) ages 18-29, 55% cisgender women, 39.5% cisgender men, 3% transgender/non-binary, completed audio-computer-assisted self-interviews.

RESULTS

Bivariate analyses indicated significant positive associations between PTSD symptoms and PrEP acceptance and self-confidence. In multinomial logistic regression analyses, after controlling for Perceived HIV Risk, participants had a higher likelihood of responding they 'probably would' take PrEP (as opposed to 'definitely would not' take PrEP) if they reported higher levels of PTSD symptoms. Post-hoc analyses revealed a curvilinear relationship between PTSD symptoms and PrEP acceptance with those reporting the highest level of PTSD in the sample having slightly lower PrEP acceptance than those reporting moderately high levels of PTSD.

CONCLUSION

Findings are discussed in the context of the negative impacts of high levels of PTSD and potential positive adaptations subsequent to moderate levels of PTSD that could be relevant to advances in HIV prevention efforts.

Clinical Efficacy and Mechanistic Insights of Anshen Dingzhi Prescription on Breast Cancer-Related PTSD Through Network Pharmacology and Molecular Docking

Anshen Dingzhi prescription (ADP) is a classic prescription of traditional Chinese medicine, which has been used in the treatment of neuropsychiatric diseases. However, its treatment of breast cancer-related post-traumatic stress disorder (BC-PTSD) lacks clinical research evidence and its mechanism is not clear. The present study investigated the efficacy and action mechanism of ADP against BC-PTSD. The results of the clinical trial showed that after 4 weeks of treatment, both groups showed reduced post-traumatic stress disorder checklist-civilian version (PCL-C), Pittsburgh sleep quality index (PSQI), self-rating depression scale (SDS) and self-rating anxiety scale (SAS) scores, and increased functional assessment of cancer therapy-breast (FACT-B) scores. The serum cortisol (CORT), tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) levels were decreased and brain-derived neurotrophic factor (BDNF) level were increased, and the improvement of serum TNF-α, IL-1β, and BDNF in treatment group was better than that of the control group. The overall treatment efficacy in the treatment group (43.90%) was superior to that in the control group (23.81%), and the overall incidence of adverse effects was lower than that in the control group. The results of network analysis and molecular docking showed that ADP blood components could act on IL1B, TNF, and BDNF. ADP contributes to the treatment of BC-PTSD symptoms, with a mechanism possibly related to its regulatory effect on TNF-α, IL-1β, and BDNF levels.Trial registration: Chinese Clinical Trial Registry, http://www.chictr.org.cn,ChiCTR2300077801.

A Retrospective Study on the Effect of Empowerment Psychological Intervention Led by Specialist Nurses on Post-traumatic Stress Disorder in ICU Patients

BACKGROUND

Many patients in the intensive care unit (ICU) suffer from post-traumatic stress disorder (PTSD), which seriously affects the treatment, recovery, and prognosis of patients.

OBJECTIVE

To observe the effect of empowerment psychological intervention on the status of PTSD in ICU patients.

METHODS

A total of 86 patients with PTSD who were treated in ICU from July 2019 to December 2021 were divided into two groups according to the intervention method. The control group (n = 43) used routine psychological intervention, while the intervention group (n = 43) used empowerment psychological intervention led by specialist nurses. The Pittsburgh Sleep Quality Index (PSQI) was used to assess the sleep quality of the patients. The Resilience Questionnaire (CD-RISC) was used to evaluate the resilience of the patients, and the Post Traumatic Stress Disorder Self-Rating Scale (PTSD-SS) was used to assess the severity of the symptoms. The Hamilton Anxiety and Depression Inventory (HAMA and HAMD) was adapted to assess the degree of anxiety and depression, and the Post-Traumatic Growth Inventory (PTGI) was adapted to evaluate the post-traumatic growth of the patients.

RESULTS

After the intervention, the total CD-RISC score and its tenacity, self-improvement, and optimism scores in the two groups were all higher than before, and the total PSQI score and its sleep quality, time, efficiency and impairment, as well as hypnotic drugs, daytime dysfunction and time to sleep were lower than before, and the CD-RISC score in the intervention group was higher than that in the control group, PSQI score was lower than that in the control group (p < 0.05). After the intervention, PTSD-SS scores and anxiety-depression scores were lower, and PTGI scores were higher in both groups than before (p < 0.05).

CONCLUSION

The empowerment psychological intervention led by specialist nurses applied to ICU patients with PTSD can improve their psychological resilience and sleep quality, reduce negative emotions, alleviate clinical symptoms, and promote post-traumatic growth.

Effects of intermittent theta-burst transcranial magnetic stimulation on post-traumatic stress disorder symptoms: A randomized controlled trial

Post-traumatic stress disorder (PTSD) is a prevalent and debilitating illness, which can be alleviated by transcranial magnetic stimulation (TMS). Intermittent theta burst stimulation (iTBS), a newer form of repetitive transcranial magnetic stimulation (rTMS), offers the advantage of shorter treatment sessions compared to the standard 10 Hz rTMS treatment. In order to compare the two forms of TMS, we enrolled 75 participants aged between 18 and 55 years who presented with (PCL-C) scale score of at least 50. Participants were randomly assigned to groups in a ratio of 1:1:1, receiving either 10 Hz rTMS, iTBS, or sham-controlled iTBS. Participants in the two treatment groups underwent 15 therapies which consisted of 1800 pulses and targeted the right dorsolateral prefrontal cortex (DLPFC). The main outcomes included changes in scores on the PCL-C and the Post-Traumatic Growth Inventory (PTGI). After intervention, the PCL-C and PTGI scores in iTBS and rTMS groups were significantly different from those in sham-controlled iTBS group. No significant differences in PCL-C and PTGI were found between the two active treatment groups. ITBS, with a shorter treatment duration, can effectively improve the symptoms of PTSD, with no significant difference in effect from that of rTMS. Future studies need to further elucidate the mechanisms, optimize the parameters and investigate the therapeutic potential and efficacy of iTBS in PTSD.

Posttraumatic Stress Disorder Symptoms and Cardiovascular and Brain Health in Women

Importance

Posttraumatic stress disorder (PTSD), cardiovascular disease (CVD), and Alzheimer disease are major public health issues, particularly for women. The implications of PTSD for cardiovascular and brain health for women is poorly understood.

Objective

To assess whether PTSD symptoms among midlife women are associated with carotid intima media thickness (IMT), an indicator of carotid atherosclerosis; brain white matter hyperintensity volume (WMHV), an indicator of brain small vessel disease; and cognitive performance and to test a modifying role of the APOEε4 genotype.

Design, Setting, and Participants

In this cross-sectional study, participants were enrolled between 2016 to 2021 and completed questionnaires (PTSD Checklist-Civilian Version), physical measures, phlebotomy, neuropsychological testing, a carotid ultrasonographic examination, and 3-Tesla brain magnetic resonance imaging. Participants included community-based women ages 45 to 67 years without a history of CVD, stroke, or dementia. Data were analyzed from July 2022 to September 2023.

Exposures

PTSD symptoms.

Main Outcomes and Measures

Outcomes of interest were associations of PTSD symptoms with carotid IMT, brain WMHV, and cognition, assessed in linear regression models. Interactions by APOEε4 were tested. Covariates included age, race and ethnicity, education, and CVD risk factors.

Results

Among 274 participants (mean [SD] age, 59.03 [4.34] years; 6 Asian participants [2.2%]; 48 Black participants [17.5%]; 215 White participants [78.5%]; 5 multiracial participants [1.8%]), 64 participants (24.71%) were APOEε4 genotype carriers. Higher PTSD symptoms were associated with greater carotid IMT (multivariable β = 0.07 [95% CI, 0.01 to 0.13]; P = .03). Associations of PTSD symptoms with neurocognitive outcomes significantly varied by APOEε4 status. Among women with APOEε4, PTSD symptoms were associated with greater whole-brain WMHV (β = 0.96 [95% CI, 0.30 to 1.63]; P = .009), periventricular WMHV (β = 0.90 [95% CI, 0.24 to 1.56]; P = .02), deep WMHV (β = 1.21 [95% CI, 0.23 to 2.20]; P = .01), and frontal WMHV (β = 1.25 [95% CI, 0.05 to 2.45]; P = .04), as well as with poorer cognition, specifically attention and working memory (β = -3.37 [95% CI, -6.12 to -0.62]; P = .02), semantic fluency (β = -6.01 [95% CI, -10.70 to -1.31]; P = .01), perceptual speed (β = -12.73 [95% CI, -20.71 to -4.75]; P = .002), and processing speed (β = -11.05 [95% CI, -17.80 to -4.30]; P = .002) in multivariable models.

Conclusions and Relevance

In this cross-sectional study of midlife women, greater PTSD symptoms were associated with higher carotid atherosclerosis and, among women who were APOEε4 carriers, greater brain small vessel disease and poorer cognitive performance. These findings point to the adverse implications of PTSD symptoms for cardiovascular and neurocognitive health among women in midlife, particularly for women who are APOEε4 carriers.

Metabolic and quality of life effects of growth hormone replacement in patients with TBI and AGHD: A pilot study

OBJECTIVE

Traumatic brain injury (TBI), a common cause of adult growth hormone deficiency (AGHD), affects 20% of Veterans returning from Iraq and Afghanistan (OEF/OIF/OND). Growth hormone replacement therapy (GHRT) improves quality of life (QoL) in AGHD but remains unexplored in this population. This pilot, observational study investigates the feasibility and efficacy of GHRT in AGHD following TBI.

DESIGN

In this 6-month study of combat Veterans with AGHD and TBI starting GHRT (N = 7), feasibility (completion rate and rhGH adherence) and efficacy (improvements in self-reported QoL) of GHRT were measured (primary outcomes). Secondary outcomes included body composition, physical and cognitive function, psychological and somatic symptoms, physical activity, IGF-1 levels and safety parameters. It was hypothesized that participants would adhere to GHRT and that QoL would significantly improve after six months.

RESULTS

Five subjects (71%) completed all study visits. All patients administered daily rhGH injections, 6 (86%) of whom consistently administered the clinically-prescribed dose. While QoL demonstrated numeric improvement, this change did not reach statistical significance (p = 0.17). Significant improvements were observed in total lean mass (p = 0.02), latissimus dorsi strength (p = 0.05), verbal learning (Trial 1, p = 0.02; Trial 5, p = 0.03), attention (p = 0.02), short-term memory (p = 0.04), and post-traumatic stress disorder (PTSD) symptoms (p = 0.03). Body weight (p = 0.02) and total fat mass (p = 0.03) increased significantly.

CONCLUSION

GHRT is a feasible and well-tolerated intervention for U.S. Veterans with TBI-related AGHD. It improved key areas impacted by AGHD and symptoms of PTSD. Larger, placebo-controlled studies testing the efficacy and safety of this intervention in this population are warranted.

Recommendations for follow-up care during post-deployment screening of Canadian Armed Forces personnel: how well does self-reported mental health predict referral decisions?

OBJECTIVE

Canadian Armed Forces (CAF) post-deployment screening aims to facilitate early care for members with mental health issues. The process consists of a questionnaire to screen for mental health problems, followed by an interview with a healthcare provider during which recommendations for follow-up care are provided if needed. In this study, we examined the association of self-reported mental health from the screening questionnaire with recommendation for follow-up care during the interview.

DESIGN

Using screening data collected from CAF members who deployed from 2009 to 2012 (n=14 957), logistic regression analysis was conducted to examine the association of self-reported mental health from the screening questionnaire with clinicians' recommendation for follow-up care.

RESULTS

In total, 19.7% of screened individuals were recommended for follow-up care. In the adjusted logistic regression model, some demographic characteristics, as well current and prior mental healthcare and self-reported mental health problems, had a substantial association with recommendation for follow-up. Compared with each mental health problem's lowest severity category, recommendation for follow-up care was higher by approximately 12%-17% for those with mild to severe depression, 7% for those with panic disorder, 8%-10% for those with mild to severe anxiety, 8% for those experiencing high levels of stressors, 4%-10% for those at risk of alcohol use disorder and 7%-12% for those at risk of post-traumatic stress disorder.

CONCLUSIONS

Although the presence of mental health problems was significantly associated with receiving a follow-up recommendation, the relationships between self-reported mental health and subsequent recommendations for care were not as high as expected. Although this may partly reflect time delays between the questionnaire and interview, further research is needed on the extent to which other factors contributed to referral decisions.

Presenting symptoms as prognostic measures of mental health recovery among service members with concussion

Background

Comorbid mental illness may negatively impact recovery from concussion. This study evaluated whether the level of symptom clusters at clinic intake contribute to poor mental health recovery in concussed patients during treatment, which may in turn serve as a target intervention.

Objective

The objective of this study is to examine the association between the level of initial symptoms and mental health symptoms among service members with concussion.

Methods

Data were obtained from 483 active duty service members treated in interdisciplinary treatment programs for traumatic brain injury, all of which were concussions. Pre-treatment symptom clusters included self-reported hyperarousal, dissociation/depression, cognitive dysfunction/headache and neurological symptoms. The outcomes, clinically-relevant decreases in depressive symptoms (assessed by the 8-item Patient Health Questionnaire, PHQ-8) and PTSD symptoms (assessed by the PTSD Checklist for DSM-5, PCL-5), were defined as a decrease in PHQ-8 > 5 and PCL-5 > 7, respectively. Poisson regression with robust error variance was used to evaluate the relationship between the level of each symptom cluster and clinically-relevant decrease in outcomes.

Results

Participants with higher (vs. lower) levels of pre-treatment hyperarousal and dissociation/depression symptom cluster were less likely to improve in depressive and PTSD symptoms during treatment. The level of cognitive/headache and neurological symptom clusters were not significantly associated with any symptom changes.

Conclusion

These findings support the need for individualized treatment for symptoms identified and treated after determining concussion history, with particular attention to high levels of hyperarousal and dissociation/depression prior to treatment.

Methodological correlates of variability in the prevalence of posttraumatic stress disorder in high-risk occupational groups: A systematic review and meta-regression

BACKGROUND

Although numerous studies have reported on PTSD prevalence in high-risk occupational samples, previous meta-analytic work has been severely limited by the extreme variability in prevalence outcomes.

METHODS

The present systematic review and meta-regression examined methodological sources of variability in PTSD outcomes across the literature on high-risk personnel with a specific focus on measurement tool selection.

RESULTS

The pooled global prevalence of PTSD in high-risk personnel was 12.1% [6.5%, 23.5%], and was similar to estimates obtained in other meta-analytic work. However, meta-regression revealed that PTSD prevalence differed significantly as a function of measurement tool selection, study inclusion criteria related to previous traumatic exposure, sample size, and study quality. PTSD prevalence estimates also differed significantly by occupational group and over time, as has also been reported in previous work, though exploratory examination of trends in measurement selection across these factors suggests that measurement strategy may partially explain some of these previously reported differences.

CONCLUSIONS

Our results highlight a pressing need to better understand the role of measurement strategies and other methodological choices in characterizing variable prevalence outcomes. Understanding the role of methodological variance will be critical for work attempting to reliably characterize prevalence as well as risk and protective factors for PTSD.

Everyday life experiences for evaluating post-traumatic stress disorder symptoms

Background: Previous research has highlighted the importance of regularizing daily routines for maintaining mental health. Little is known about whether and how regularity of daily routines is associated with reduced post-traumatic stress disorder (PTSD) symptoms.Objective: We aimed to examine the associations between regularity of daily routines and PTSD symptoms in two studies (N = 796).Method: In Study 1, prospective data were analysed with the latent change score model to investigate the association between sustainment of regular daily routines and change in PTSD symptoms over time amid massive civil unrest in Hong Kong in 2019. Study 2 used vignette as a quasi-experimental method to assess the ability of maintaining regular daily routines in face of a major stressor, and tested its associations with PTSD symptoms.Results: In Study 1, increased regularity of diverse daily routines was inversely associated with increased PTSD symptoms amid the civil unrest in Hong Kong (β = -.427 to -.224, 95% confidence intervals [-.543 to -.359, -.310 to -.090], p values < .01). In Study 2, a greater ability to maintain regular daily routines during stress was associated with lower levels of PTSD symptoms (β = -.285 to -.096, 95% confidence intervals [-.379 to -.189, -.190 to -.003], p values < .05).Conclusions: Our findings suggest the benefit of considering diverse everyday activities in evaluating PTSD symptoms in both clinical and subclinical populations. Interventions with the direct focus on the role of daily living could promote psychological resilience during and after potentially traumatic events.

Landslide disasters in eastern Uganda: post-traumatic stress disorder and its correlates among survivors in Bududa district

BACKGROUND

Post-traumatic stress disorder is the commonly reported psychiatric morbidity among the survivors of natural disasters. However, its prevalence particularly in Bududa, Eastern Uganda is largely unknown.

AIMS AND OBJECTIVES

To assess the prevalence and correlates of post-traumatic stress disorder among Bududa landslide survivors.

METHODS

A community-based cross-sectional study was conducted on a sample of 587 participants. The study setting was the Bududa district, with a multistage sampling method. Pre-tested, administered interviewer PTSD Checklist-civilian version was used as screening tools between 4th and April 29th 2022. Data were analyzed using descriptive and binary logistic approaches at a 5% level of significance.

RESULTS

Of the study participants, 276 (46.8%) had PTSD symptoms. Among the respondents, 250 (42.6%) were in the age range of 40 and above, 396 (67.3%) were female, 284 (48.4%) had no formal education, and 333 (56.7%) were married. Results showed that male gender (AOR: 0.47; 95% CI 0.31-0.73; p = 0.001), widowhood (AOR: 0.44; 95% CI 0.21-0.94; p = 0.034), lack of counseling (AOR: 0.44; 95% CI 0.21-0.94; p = 0.001), and duration since the landslide (AOR: 0.35; 95% CI 0.23-0.52; p = 0.001) were associated with an increased likelihood of screening for PTSD in landslide survivors.

CONCLUSION

Landslides pose significant effects on the mental health of survivors. In the present study, the extent of PTSD among survivors is substantially high. male gender,, widowhood, lack of counselling, low social support, and duration since the landslide were significantly associated with PTSD. Effective screening and awareness programs among survivors should be strengthened for the prevention and treatment of psychiatric morbidity among the survivors of landslides.

The relative impact of injury and deployment on mental and physical quality of life among military service members

US service members injured in the recent conflicts in Iraq and Afghanistan were more likely to survive than those in previous conflicts because of advances in medicine and protective gear. However, there is limited research examining the long-term impact of injuries while deployed on physical and mental quality of life (QOL) among service members. We used data from two time-points with an average follow-up period of 4.27 years (SD = 2.13; n = 118,054) to prospectively examine the association between deployment and injury status with QOL. Data were derived from the Millennium Cohort Study surveys (2001 to 2016) and linked with the Department of Defense Trauma Registry (DoD-TR) among a cohort of US service members from all branches and components. The primary predictor (a combination of deployment and injury status) was comprised of the following four categories: 1) not deployed, 2) deployed and not injured, 3) deployed and non-battle injured, and 4) deployed and battle injured. Demographic, military, psychological and behavioral health, and life stress factors were adjusted for in multivariable models. Outcomes of interest were physical and mental QOL from the Short-Form Health Survey for Veterans (VR-36) measured at ~4 year follow-up. Between group comparisons indicated that those deployed and battle-injured had the greatest decline in both mental (-3.82) and physical (-10.13) QOL scores over time (p < .05). While deployment and injury status were associated with poorer mental and physical QOL in adjusted models; only the association between deployment and injury status with physical QOL was clinically meaningful (more than 2.5). In adjusted models, Time 1 mental and physical QOL explained most of the variance (23–25%) in Time 2 mental and physical health QOL as compared to other covariates (e.g., injury and deployment, and other sociodemographic factors increased variance by ~5%). Time 1 QOL was the most significant predictor of later QOL, but those injured while deployed experienced significant and meaningful decrements to long-term physical QOL. This suggests that prevention and rehabilitation interventions should focus on improving physical health among injured service members to avoid long-term adverse effects.

Association of Problematic Anger With Long-term Adjustment Following the Military-to-Civilian Transition

Importance

Few studies have examined the role of problematic anger in long-term adjustment of service members transitioning out of the military.

Objective

To determine the prevalence of problematic anger during the military-to-civilian transition period and the association of problematic anger with adjustment to civilian life.

Design, Setting, and Participants

This cohort study used 2 waves of survey data administered approximately 5 years apart (time 1 [T1; September 26, 2014, to August 25, 2016] and time 2 [T2; October 23, 2019, to August 31, 2021]) from the Millennium Cohort Study, a population-based military study. Participants were US active-duty service members within 24 months of separating from military service at T1. Statistical analysis was performed from September 2021 to May 2022.

Exposures

Problematic anger was operationalized as scoring at least 12 points on the 5-item Dimensions of Anger Reactions scale at T1.

Main Outcomes and Measures

Behavioral and functional health (depression, posttraumatic stress disorder, problem drinking, functional limitations), relationship health (relationship quality, coping with parental demands, social support), and economic health (major financial problems, financial insecurity, homelessness, employment status) were assessed at T2. Covariates, assessed at T1, included demographics, military characteristics, mental health, problem drinking, and physical health.

Results

Of the 3448 participants, 2625 (76.1%) were male, 217 (6.3%) were Hispanic, 293 (8.5%) were non-Hispanic Black, and 2690 (78.0%) were non-Hispanic White; the mean (SD) age was 40.1 (8.5) years; 826 (24.0%) met criteria for problematic anger. Prevalence of problematic anger was 15.9% (95% CI, 12.2%-19.7%) 24 months prior to military separation and 31.2% (95% CI, 26.2%-36.2%) 24 months following separation. After adjusting for covariates, problematic anger was associated with greater likelihood of behavioral and functional health outcomes (eg, posttraumatic stress disorder: adjusted odds ratio, 1.55, 95% CI, 1.23-1.96), relationship health difficulties (eg, low social support: aOR, 1.66; 95% CI, 1.23-2.24), and economic difficulties (eg, substantial financial insecurity: aOR, 1.64; 95% CI, 1.13-2.39) at T2.

Conclusions and Relevance

This cohort study found an association between prevalence of problematic anger during the military-to-civilian transition and problematic anger with subsequent adjustment difficulties among US service members. These findings suggest the need to equip service members proactively with skills to identify and manage anger as a way to support them before and during this period of transition.

Post-Traumatic Stress Disorder Among U.S. Army Drone Operators

INTRODUCTION: Exposure to traumatic events could increase post-traumatic stress disorder (PTSD) risk among enlisted U.S. Army drone operators. Published research on PTSD risk in this population is unavailable.METHODS: We used a combined medical and administrative longitudinal dataset to examine adjusted associations between drone operator service among U.S. Army enlisted members and three PTSD indicators: whether screened via the PTSD Checklist – Civilian (PCL-C); PCL-C scores; and incident PTSD diagnoses. We compiled summary statistics for and conducted tests of differences in independent variable distributions when comparing drone operators and others. Two multivariable survival regression models and an ordinary least squares model were used to estimate adjusted associations.RESULTS: There were 1.68 million person-years of observed time in the study population (N = 678,548; drone operator N = 2856). Compared to other servicemembers, the adjusted likelihood of undergoing PTSD screening was 35% lower [95% confidence interval (CI) for the adjusted hazard ratio (aHR): 0.56–0.76]. Among subjects who took the PCL-C, scores did not differ significantly on the basis of drone operator service (adjusted change: −1.26 points; CI: −3.41–0.89). The adjusted hazard of receiving a PTSD diagnosis was 34% lower among drone operators (CI: 0.54–0.80).DISCUSSION: These findings provide reassurance that enlisted U.S. Army drone operators are not at increased risk of PTSD. Further research is needed in order to identify the mechanisms of the decreased PTSD risk observed, and whether other or longer-term mental health risks are present among those in this occupation.Nelson DA, Wilson M, Kurina LM.

Post-Traumatic Stress Disorder and Coping Strategies Among People with HIV in Lira District, Uganda: A Cross-Sectional Study

Background

Post-traumatic stress disorder (PTSD) is the most commonly reported mental health consequence following traumatic events. However, little is known about how people with HIV cope with the PTSD burden in Lira city, northern Uganda.

Materials and Methods

This study was carried out in Lira District Health Centre IVs from February 10, 2022, to March 10, 2022. A facility-based cross-sectional study was employed among 390 people with HIV attending Lira Health Centre IVs. A consecutive sampling technique was used to select the sample size. Questionnaires were used to collect data. A binary logistic regression model was fitted to identify factors associated with independent variables, and AOR was employed to estimate the strength of association between independent and dependent variables.

Results

Results show that the estimated prevalence of PTSD was 254 (65.1%) and was higher among the females 191 (75.2%), those with no formal education 143 (56.3%), aged 40 years and above 121 (47.6%), and married 127 (50.0%). Results indicate that male respondents had a 51% reduced odds of developing PTSD burden compared to female respondents (AOR: 0.49; 95% CI: 0.30–0.81; P = 0.005). Individuals who did not use planning activities as a coping strategy had more than 2-fold increased odds of experiencing PTSD compared to those who planned activities (AOR: 2.43; 1.26–4.70; P = 0.008). Participants who did not have emotional support had close to 3-fold increased chances of developing PTSD compared to those who had emotional support (AOR: 2.94; 1.74–4.98; P ≤ 0.001). Participants who indicated they were not taking recourse to spirituality had more than 4-fold increased odds of experiencing PTSD compared to those who had spirituality (AOR: 4.40; 1.83–10.46; P = 0.001).

Conclusion

A considerable burden of PTSD among HIV clients attending health centre IVs in Lira District was notably higher and was associated with gender, planning activities, emotional support and spirituality. Early screening of PTSD among HIV clients is needed to alleviate the burden. There is also a need to include PTSD treatment services in the treatment programme of HIV care services in health centre IVs in Lira District.

Engagement in and Benefits of a Short-Term, Brief Psychotherapy Intervention for PTSD During Pregnancy

Trauma-related symptoms and post-traumatic stress disorder (PTSD) are common during pregnancy and have adverse effects on pregnancy and birth outcomes, post-partum maternal mental health, and child development. The arousal symptoms associated with PTSD, including heightened or dysregulated physiology, may contribute to these adverse outcomes. Low-income minoritized women may be at highest risk given more lifetime exposure to trauma and limited access to mental health care. While evidence-based psychotherapies for PTSD exist, none are targeted to non-treatment seeking individuals nor specifically integrated with prenatal care. Thus, we developed and tested the efficacy of a short-term (four sessions) brief (30-45 min) psychotherapeutic intervention designed to address PTSD symptoms in pregnant women receiving prenatal care at two urban medical centers. Participants were 32 pregnant women with an average gestational age of 18.5 weeks at the time of enrollment. The sample was overwhelmingly non-Caucasian, single, and reported very low income. Participants completed measures of trauma-related symptoms (Post-traumatic Stress Disorder Checklist, PCL), and depression (Edinburgh post-natal Depression Scale, EPDS) at baseline, twice during treatment, post-treatment, and at 10-14 weeks post-partum. The intervention was successful at significantly decreasing symptoms of PTSD (PCL score = -20.27, 95% CI: -25.62, -14.92, P < 0.001, W = -7.43) and depression (EPDS score = -4.81, 95% CI: -7.55, -2.06, P = 0.001, W = -3.23) by the final session. These benefits were sustained at post-treatment and post-partum follow ups. Future research should further explore the effectiveness of this treatment in a randomized controlled trial.

The structure of PTSD. Development of the Post Traumatic Symptom scale from a clinician-based perspective

BACKGROUND

Nations marked by a Marxist-Leninist ideology have suffered greatly due to a culture of abuse emphasized by the absolute absence of psychology, thus contributing to a diminished ability in recognizing the consequences of traumatic experiences.

OBJECTIVE

To improve the assessment of the presence and severity of posttraumatic stress disorder (PTSD) in such a cultural context, our paper aimed at developing an alternative self-report measure for PTSD - the Post Traumatic Symptom Scale (PTSs), developed by clinicians with wide relevant expertise, based on the natural language people use to describe its subjective experience. This research used multiple samples consistent with the corresponding objectives. Mokken Scale Analysis and the Classical Test Theory were both employed. The proposed scale was tested against five competing PTSD models, whilst also investigating the symptoms' clusters in two different samples by using, to our knowledge, a network analysis approach for the first time.

METHOD

The results indicated excellent psychometric properties regarding internal consistency and temporal reliability, as well as convergent and discriminant validity. The results of MSA showed that the scale fully conforms to the assumptions of the monotone homogeneity model, interpreted as positive evidence for its use in clinical purposes. The factor analyses pointed that the newer models outperformed the standard DSM-5 model, with bifactor models displaying better fit indexes than second-order models. Finally, a distinct pattern of symptom activation in the high-risk group (i.e. first-responders) was found, bringing support for symptoms overlapping between PTSD and affective disorders, thus reinforcing the idea of bridge symptoms which has significant clinical implications.

RESULTS

This study presents an alternative sound instrument for measuring PTSD symptomatology focused on how people naturally describe their subjective experiences. Theoretical and practical implications are discussed alongside limitations.

HIGHLIGHTS

The construction of PTSs encompasses cultural trauma and one's subjective experience.PTSs was tested against the five major competing models of PTSD.Network analyses suggest different patterns in a student sample vs. a first-responders one, with the accent on the negative alterations in cognitions and mood (NACM) model.

A Crosswalk Study of DSM-IV and DSM-5 Criteria for PTSD from the DSM-5 Field Trials

Objective: Posttraumatic stress disorder (PTSD) is prevalent and sometimes severely disabling. Providing effective treatment for PTSD and addressing its social consequences require accurate diagnosis. PTSD criteria have changed in all editions of the American Diagnostic Criteria since introduction of the diagnosis in DSM-III in 1980. The DSM-5 Field Trials demonstrated very good inter-rater reliability for PTSD, but a crosswalk study comparing DSM-IV and DSM-5 criteria has potential to identify diagnostic differences generated by changed criteria. Methods: A DSM-IV to DSM-5 PTSD crosswalk study was conducted in real-world adult clinical treatment settings in two DSM-5 Field Trials sites, the Dallas (N = 93) and Houston (N = 48) Veterans Affairs medical centers. The crosswalk assessment was conducted by trained clinicians who interviewed the patients and rated both sets of criteria on a combined checklist. Results: PTSD prevalence differed insubstantially between criteria sets (42% vs. 45% and 55% vs. 52% in the Dallas and Houston sites, respectively), with moderate to excellent diagnostic agreement (reliability indicated, respectively, by κ = .53 and .93); however, substantial proportions of individuals diagnosed in one criteria set did not meet criteria in the other. Differences in cross-criteria diagnostic reliability were largely a function of differing definitions of criterion A trauma. Conclusions: Reliability across the two criteria sets was generally good to excellent, and diagnostic discrepancy predominantly reflected the elimination of criterion A2 in DSM-5 with a smaller contribution from changes to the avoidance and numbing criteria.

Prevalence and Temporal Trends Analysis of Screening and Diagnostic Instruments in Posttraumatic Stress Disorder: Text Mining Study

BACKGROUND

Various instruments for patient screening and diagnosis have been developed for and applied in posttraumatic stress disorder (PTSD).

OBJECTIVE

This study comprehensively investigates the prevalence and temporal trends of the most widely used instruments in PTSD-related studies.

METHODS

A total of 1345 files of registered clinical trials from ClinicalTrials.gov and 9422 abstracts from the PubMed database from 2005 to 2020 were downloaded for this study. The instruments applied in clinical trials were manually annotated, and instruments in abstracts were recognized using exact string matching. The prevalence score of an instrument in a certain period was calculated as the number of studies divided by the number of instances of the instrument. By calculating the yearly prevalence index of each instrument, we conducted a trends analysis and compared the trends in index change between instruments.

RESULTS

A total of 4178 instrument synonyms were annotated, which were mapped to 1423 unique instruments. In the 16 years from 2005 to 2020, only 10 instruments were used more than once per year; the 4 most used instruments were the PTSD Checklist, the Clinician-Administered PTSD Disorder Scale, the Patient Health Questionnaire, and the Beck Depression Inventory. There were 18 instruments whose yearly prevalence index score exceeded 0.1 at least once during the 16 years. The changes in trends and time points of partial instruments in clinical trials and PubMed abstracts were highly consistent. The average time duration of a PTSD-related trial was 1495.5 days or approximately 4 years from submission to ClinicalTrial.gov to publication in a journal.

CONCLUSIONS

The application of widely accepted and appropriate instruments can help improve the reliability of research results in PTSD-related clinical studies. With extensive text data obtained from real clinical trials and published articles, we investigated and compared the usage of instruments in the PTSD research community.

Brainstem Quadruple Aberrant Hyperphosphorylated Tau, Beta-Amyloid, Alpha-Synuclein and TDP-43 Pathology, Stress and Sleep Behavior Disorders

Quadruple aberrant hyperphosphorylated tau (p-τ), amyloid-β peptide, alpha-synuclein and TDP-43 brainstem and supratentorial pathology are documented in forensic ≤40y autopsies in Metropolitan Mexico City (MMC), and p-τ is the major aberrant protein. Post-traumatic stress disorder (PTSD) is associated with an elevated risk of subsequent dementia, and rapid eye movement sleep behavior disorder (RBD) is documented in PD, AD, Lewy body dementia and ALS. This study aimed to identify an association between PTSD and potential pRBD in Mexico. An anonymous online survey of 4502 urban college-educated adults, 29.3 ± 10.3 years; MMC, n = 1865; non-MMC, n = 2637, measured PTSD symptoms using the Impact of Event Scale-Revised (IES-R) and pRBD symptoms using the RBD Single-Question. Over 50% of the participants had IES-R scores ≥33 indicating probable PTSD. pRBD was identified in 22.6% of the participants across Mexico and 32.7% in MMC residents with PTSD. MMC subjects with PTSD had an OR 2.6218 [2.5348, 2.7117] of answering yes to the pRBD. PTSD and pRBD were more common in women. This study showed an association between PTSD and pRBD, strengthening the possibility of a connection with misfolded proteinopathies in young urbanites. We need to confirm the RBD diagnosis using an overnight polysomnogram. Mexican women are at high risk for stress and sleep disorders.
