Network analysis of posttraumatic stress disorder in a treatment-seeking sample of US firefighters and emergency medical technicians.

BACKGROUND: First responders, including firefighters and emergency medical technicians (EMTs), are under extreme stress from repeated exposure to potentially traumatic events. To optimize treatment for this population, it is critical to understand how the various posttraumatic stress disorder (PTSD) symptom factors are associated with one another so these relations may be targeted in treatment. METHOD: Using a sample of treatment-seeking firefighters/EMTs (N = 342), we conducted a partial correlation network analysis of the eight-factor model. A Bayesian directed acyclic graph (DAG) was used to estimate causal associations between clusters. RESULTS: Approximately 37 % of the sample screened positive for probable PTSD. Internal re-experiencing and external re-experiencing had the strongest edges. In the DAG, internal re-experiencing was the parent node and was potentially predictive of external re-experiencing, negative affect, dysphoric arousal, and avoidance. LIMITATIONS: Data were drawn from a treatment-seeking sample that may not generalize to all firefighters/EMTs. CONCLUSIONS: The current findings are consistent with prior research suggesting re-experiencing plays a critical role in developing and maintaining PTSD symptoms. Future research should investigate non-treatment-seeking first responders, as well as EMTs and firefighters as individual populations.

Validation of the PCL-5, PHQ-9, and GAD-7 in a Sample of Veterans.

OBJECTIVE: Veterans can present at nongovernment (Department of Defense, Department of Veterans Affairs) mental health agencies with complex symptom constellations that frequently include posttraumatic stress disorder, depression, and generalized anxiety. To date, no veteran study has validated these measures on a treatment-seeking sample of veterans outside the DoD and VA. METHODS: We used a treatment-seeking sample of veterans ( N = 493) to validate measures that assess these constructs (PTSD Checklist 5, Patient Health Questionnaire-9, and Generalized Anxiety Disorder-7). RESULTS: The seven-factor posttraumatic stress disorder hybrid configuration was the best fit. The best fitting model of the depression measure was a two-factor structure, cognitive-affective, and somatic depression. The measure of generalized anxiety was a unidimensional model. LIMITATIONS: Follow-up studies should validate these measures on nontreatment-seeking discharged veterans. CONCLUSIONS: We interpret these findings within the veteran scholarship and explore clinical implications for providers.

"Knowing when it's time to take a break": Nursing home social workers' coping during COVID-19.

Background: Nursing home (NH) social workers face many challenges in meeting the psychosocial needs of residents while balancing their own well-being needs. Methods: This study employed a cross-sectional survey of NH social workers via social media and professional networks about their coping strategies during COVID-19. Open-ended responses were analyzed qualitatively using the rigorous and accelerated data reduction technique (RADaR). Results: The study included a sample of 63 (N = 63) NH social workers. Four themes defined ways the in which NH social workers coped with stress during COVID-19, including relying on friends and family, mindfulness and spirituality/religion, self-care strategies, and setting boundaries at work. Conclusion: These techniques appear to be effective; however there remains a need for institutional programs and policies to provide the time and space to holistically support coping in NH social workers and to prevent burnout and turnover, particularly during times of crisis.

Psychometric Properties of the Patient Activation Measure in Family Caregivers of Patients With Chronic Illnesses.

BACKGROUND: The Patient Activation Measure (PAM) is used clinically and in research to measure an individual's knowledge, skills, and confidence related to their health management engagement. Despite the use of "patient" in the title, the instrument can be used in nonpatient populations. A group at high risk for low activation concerning their own health is family caregivers of patients with chronic illnesses. The psychometric properties of the PAM have not been established in family caregivers. OBJECTIVES: This study aimed to examine the psychometric properties of the PAM 10-item version (PAM-10) in a sample of family caregivers of patients with chronic illnesses. Our focus was on family caregivers' health activation of their own healthcare needs. METHODS: We evaluated the internal consistency reliability of the PAM-10 in a sample of 277 family caregivers. Item-total correlations and interitem correlations were used to assess item homogeneity. Construct validity of the PAM-10 was examined using exploratory factor analysis and testing hypotheses on known relationships. RESULTS: The PAM-10 demonstrated adequate internal consistency. Item-total correlation coefficients and interitem correlation coefficients were acceptable. Construct validity of the instrument was supported. Factor analysis yielded two factors that explained 62.3% of the variance in the model. Lower levels of depressive symptoms were significantly associated with better activation, providing evidence of construct validity. Caregivers with high activation levels were significantly more likely to engage in and adhere to self-care behaviors such as regular exercise, eating a healthy diet, and engaging in stress reduction strategies. DISCUSSION: This study demonstrated that the PAM-10 is a reliable and valid measure for family caregivers of patients with chronic illnesses to measure caregivers' health activation of their own healthcare needs.

Validation of the PCL-5, PHQ-9, and GAD-7 in a Sample of First Responders.

OBJECTIVE: First responders (FRs) commonly present for treatment with complex symptom constellations that frequently include posttraumatic stress disorder, depression, and generalized anxiety. To date, no FR study has validated these measures on a treatment-seeking sample. METHODS: Confirmatory factor analysis was utilized to validate measures that assess these constructs (Posttraumatic Stress Disorder Checklist for DSM-5, Patient Health Questionnaire-9, and Generalized Anxiety Disorder-7) on a treatment-seeking sample of FRs ( N = 390). RESULTS: The seven-factor posttraumatic stress disorder hybrid configuration was the best fit. The best fitting factor model of the depression measure was a two-factor structure, cognitive-affective and somatic depression. Lastly, generalized anxiety was a unidimensional construct. LIMITATIONS: Follow-up studies should validate these measures on each FR subtype. CONCLUSION: We position these findings within the FR literature, review clinical implications for providers, and offer recommendations for future research.

Predictors of Suicide and Differences in Attachment Styles and Resilience Among Treatment-Seeking First-Responder Subtypes.

OBJECTIVE: To identify the predictors of suicide for firefighters (FFs), emergency medical technicians (EMTs), and law enforcement officers (LEOs). METHODS: We used baseline data from FFs/EMTs (n = 69) and LEOs (n = 81) to investigate the unique predictors for both first-responder subtypes. We conducted confirmatory factor analysis on validated assessments of posttraumatic stress disorder (PTSD) and depression. Measures of attachment, resilience, PTSD, depression, generalized anxiety, trauma history, and substance use were the independent variables in two backward stepwise regressions predicting suicide. RESULTS: Substance use and somatic depression were significant predictors for LEOs, whereas affective depression, anhedonia, externalizing behaviors, trauma history, and generalized anxiety were significant predictors for FFs/EMTs. LIMITATIONS: These data are cross-sectional and should be modeled longitudinally over the course of treatment. CONCLUSION: Separate constructs influence suicide for LEOs and FFs/EMTs.

Differences in Resilience and Mental Health Symptoms Among US First Responders With Secure and Insecure Attachment.

OBJECTIVE: This observational study aimed to determine whether attachment style predicted first responders' mental health and resilience. METHOD: Data were from a treatment-seeking sample of first responders ( N = 237). Each participant completed six assessments measuring attachment, resilience, generalized anxiety, depression, suicidality, and posttraumatic stress disorder. RESULTS: On the attachment assessment, 25.3% were categorized as secure, 19.0% as dismissive, 25.3% as preoccupied, and 30.4% as fearfully attached. As predicted, securely attached participants had the lowest scores for generalized anxiety, depression, suicidality, and posttraumatic stress disorder and the highest scores on the resiliency measure, followed by dismissive, preoccupied, and fearfully attached participants. LIMITATIONS: These data are cross-sectional and causality cannot be inferred. CONCLUSIONS: Results highlight the importance of the study of attachment to psychotherapy and mental health treatment with first responders.

A Pilot Study of a Three-Session Heart Rate Variability Biofeedback Intervention for Veterans with Posttraumatic Stress Disorder.

Many veterans do not complete traditional trauma treatments; others may continue to struggle with posttraumatic stress disorder (PTSD) even after completing a full course of therapy (Blasé et al., in Int J Environ Res Public Health 18(7):Article 3329, https://doi.org/10.3390/ijerph18073329 , 2016). Heart rate variability (HRV) biofeedback (HRVB) is a non-invasive, non-pharmacological, breathing-based cardiorespiratory training technique that can reduce trauma symptoms and improve HRV parameters. Prior studies have demonstrated HRVB is well-tolerated by veterans with PTSD symptoms (Tan et al., in Appl Psychophysiol Biofeedback 36(1):27-35, 10.1007/s10484-010-9141-y, 2011; Schuman and Killian, in Appl Psychophysiol Biofeedback 44(1):9-20, https://doi.org/10.1007/s10484-018-9415-3 , 2019). This randomized wait-list controlled pilot study tested a short mobile app-adapted HRVB intervention in combination with treatment as usual for veterans with military-related PTSD to determine if further investigation was warranted. We assessed veterans' military-related PTSD symptoms, depression symptoms, and HRV time and frequency domain measures at baseline, after three clinical sessions, and one month later. This study combined clinical training and home biofeedback with a smartphone app and sensor to reinforce training and validate adherence. In the intervention group, depression and SDNN significantly improved, and we observed marginally significant improvements for PTSD Cluster B (intrusion) symptoms, whereas no significant improvements were observed in the control group. In addition, the brief protocol was acceptable to veterans with PTSD with over 83% of participants completing the study. However, adherence to home practice was low. Findings suggest brief HRVB interventions can decrease comorbid depression and improve overall autonomic function in veterans with PTSD; however, additional research on home biofeedback is necessary to determine the best strategies to increase adherence and which veterans would benefit from brief HRVB interventions.

Affective Depression Mediates PTSD to Suicide in a Sample of Treatment-Seeking First Responders.

OBJECTIVE: The aim of this study was to examine the associations of comorbid posttraumatic stress disorder (PTSD), affective or somatic depression, and suicide among first responders (FRs). METHOD: We used baseline data from FRs ( N = 232) who sought services at a nonprofit mental health agency specializing in treating trauma exposed FRs. We conducted two PROCESS simple mediation models with PTSD as the predictor, affective depression and somatic depression as the mediators, and suicidality as the dependent variable. RESULTS: Affective depression significantly mediated the relationship between PTSD and suicidality, whereas somatic depression did not. The direct effect of PTSD on suicidality was not significant. LIMITATIONS: These data are cross-sectional and should be followed up with longitudinal analyses across the course of treatment. CONCLUSIONS: To reduce suicide risk, it is recommended that clinicians target affective depression instead of PTSD symptoms.

Differences in Suicidality in Non-Treatment-Seeking and Treatment-Seeking Law Enforcement Officers: A Cross-sectional Study.

OBJECTIVE: Law enforcement officers (LEOs) are exposed to high levels of occupational trauma and face added stress from heightened public scrutiny and COVID-19, which may result in suicide. It is crucial to understand differences between LEOs who seek treatment and those who do not. METHOD: We compared LEOs from the same greater metropolitan area who sought treatment with those who did not. Participants completed validated measures assessing posttraumatic stress disorder, generalized anxiety, depression, and suicidality. RESULTS: The treatment-seeking sample scores were higher on all standardized assessments. Bivariate logistic regression results indicated that the non-treatment-seeking sample's odds of experiencing suicidality were 1.76 times the odds for the treatment seeking sample. Conclusions: This suggests that many LEOs experiencing suicidality may not be seeking treatment and highlights the role that posttraumatic stress disorder may play in determining whether LEOs seek treatment or not.

Profile of informal rural Appalachian caregivers of patients with chronic illnesses.

PURPOSE: Caring for a family member with chronic illness increases cardiovascular disease (CVD) risk by 82%, and rurality imparts additional CVD disparities. The purpose of this study was to describe a profile of rural caregivers of patients with chronic illnesses to determine the prevalence of CVD risk factors, and psychosocial and socioeconomic burden, as well as to compare these variables across gender. METHODS: Baseline data from a trial of CVD risk reduction in rural caregivers of patients with chronic illnesses were used. We measured depression and anxiety with the PHQ-9 and Brief Symptom Inventory; social, economic, and environmental factors using the MOS-Social Support and Economic and Environmental surveys; body mass index (BMI); blood pressure (BP); and lipid profile. RESULTS: Of 181 caregivers (age 53±14 years, 80% female), 69% were married; 88% were caring for a family member, including 46% caring for a spouse and 18% for a parent. A total of 51% were anxious, 25% depressed, and 25% reported lack of social support. Most (51%) caregivers had one or more types of CVD; and 49% were smokers. By examination, 76% had elevated BP; 35% had total cholesterol >200; 50% low-density lipoprotein >100; 56% triglycerides >150; and 79% high-density lipoprotein <60. Based on BMI, 91.5% were overweight or obese. Gender comparisons revealed that women reported higher levels of depressive symptoms than men. CONCLUSIONS: Rural caregivers, regardless of gender, are at increased risk of CVD and struggle with factors that make caregiving burdensome and contribute to their own poor cardiac health.

The suicide of Private Danny Chen: An interpersonal theory perspective.

Despite considerable prevention and intervention efforts, military suicide rates have increased. Although most research on active-duty military suicide has focused on combat exposure, evidence shows that bullying, hazing, and race are understudied risk factors for military suicide. According to the interpersonal theory of suicide, thwarted belongingness, perceived burdensomeness, and acquired capability are necessary components for enacting a suicide death. In this theoretically-based interpersonal case analysis of the suicide death of Private Danny Chen, an American soldier of Chinese descent, we explore how bullying, hazing, and race may have intersected with other vulnerabilities to result in his death.

Scoping Review: Ethical Considerations in Online Ethnographic Research With Military Populations.

Researchers using online ethnographic methods to study military communities must employ higher standards of ethical practice. Military populations may face significant risk if reidentified in research. These requirements are especially salient for online data collection. This review questions how and to what extent military online ethnographers are addressing ethics considerations. We charted evidence from seven military studies using an online ethnographic method. Findings reveal that most online military ethnographers did not utilize sufficient ethical safeguards in their studies. Additionally, they did not document or transparently disclose the ethical steps they may have taken. This study argues implementing ethical safeguards is especially important for protecting vulnerable military populations. We present a strategy for evaluating ethics practices in online ethnographic research and provide best practices for military online ethnographers.

Risk and protective factors of dementia among adults with post-traumatic stress disorder: a systematic review protocol.

INTRODUCTION: Post-traumatic stress disorder (PTSD) is associated with an increased risk of dementia. Individual epidemiological studies have controlled for several confounders of the relationship between PTSD and increased dementia risk, yet particular risk factors underlying this relationship have not been determined. This systematic review protocol aims to identify risk and protective factors of dementia among adults with PTSD. METHODS AND ANALYSIS: We will conduct an electronic search of the databases: PubMed, CINAHL, PsychINFO, The Cochrane Library, Scopus and ProQuest Dissertation and Theses Global. After screening the studies, quantitative synthesis will be performed, if possible. Otherwise, a narrative synthesis will be performed. We will include randomised controlled trials and other types of research evidence including longitudinal cohort studies. Strength of evidence will be assessed using the Grading of Recommendations, Assessment, Development and Evaluations method. Examples of variables that will be extracted are: year of PTSD diagnosis, comorbid conditions, health behaviours, pharmacological treatments and year of mild cognitive impairment or dementia diagnosis. We developed this systematic review protocol according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols 2015 statement. ETHICS AND DISSEMINATION: The proposed study will not collect individual-level data and, therefore, does not require ethical approval. Results of this study will provide current evidence on risk and protective factors of dementia in adults with PTSD. Findings will be disseminated in peer-reviewed publications and conference presentations. PROSPERO REGISTRATION NUMBER: CRD42019128553.

Dying Online: An Analysis of End-of-Life Narratives.

Technology is changing many aspects of our daily lives including how we share our experiences. While there have been many advances in technology to sustain life, it has also led to changes in how we die. This study utilized publicly available online narratives (vlog postings) written by individuals diagnosed with a terminal illness to explore themes on what dying individuals wished to say about their experiences (n = 39). While the content of the messages varied, universally all postings provided advice for living a good life. The implications of these narratives are still unknown. Questions remain about the role online peer support plays in the dying process and the extent to which sharing one's digital story can affect others online. The act of being introspective at the end of life and the desire for social connection is similar to other forms of social work intervention such as dignity therapy suggesting an opportunity for further exploration. Additionally, these end-of-life narratives could also serve as a tool for educating future social work professionals about the experiences of those diagnosed with a terminal illness.

The relationship between psychological states and health perception in individuals at risk for cardiovascular disease.

Backgrounds: Perceptions of health are important to motivate people to change behaviors. Non-adherence to healthy behaviors that prevent cardiovascular disease may result from inadequate health perceptions. However, there are few studies investigating relationships between health perceptions and psychological states. Objective: To determine whether psychological states (ie, depressive symptoms and anxiety) are associated with the congruency between health perception and estimated risk for cardiovascular disease in adults with 2 or more cardiovascular disease risk factors. Methods: Community dwellers at risk for cardiovascular disease were asked to complete the Patient Health Questionnaire-9 and the anxiety subscale of the Brief Symptom Inventory to measure depressive symptoms and anxiety, respectively. Participants rated their perceived health from excellent to poor. The estimated cardiovascular disease risks were measured with the 10-year cardiovascular disease Framingham risk scores. Participants were grouped into three health perception groups based on congruency between levels of health perception and cardiovascular disease risk. Multivariate multinomial logistic regression was done to examine the association between psychological states and health perception groups. Results: Of 828 participants 54.7%, 12.0%, and 33.3% had congruent, pessimistically biased, and optimistically biased health perception, respectively. Depressive symptoms were significantly associated with pessimistic bias (adjusted odds ratio: 1.070, 95% confidence interval 1.010-1.133), but not anxiety. Optimistic bias was not associated with either depressive symptoms or anxiety. Conclusions: A mismatch between individual health perceptions and cardiovascular disease risks was associated with depressive symptoms. As health perception is affected by depressive symptoms, clinicians should assess depressive symptoms when exploring health perceptions and engaging individuals in decision-making about a healthy lifestyle.

Suicide in U.S. Women Veterans: An Interpersonal Theory Perspective on Suicide Prevention Policies.

Increases in suicide rates for U.S. women Service Members and Veterans have emerged as a public health issue of great concern. Women Veterans are more likely than their civilian counterparts to die by suicide, and rates of suicide for women Veterans are rising faster than rates for male Veterans. Given higher rates of suicide in combat-exposed males and increased rates of suicide associated with military deployment for women, the expansion of women into direct combat roles may further escalate their rates of suicide. The interpersonal theory of suicide provides a framework for the examination of women Veterans' risk factors and how implementation of policy provisions can more effectively ameliorate suicide risk. Recent suicide prevention policy initiatives that target women Veterans' unique needs are important steps; however, suicide prevention efforts should address specific risk factors contributing to thwarted belongingness, perceived burdensomeness, and the acquired capability for suicide in Veteran women.

A systematic review of the psychosocial impact of emotional numbing in US combat veterans.

CONTEXT: Previous studies have linked posttraumatic emotional numbing symptoms in US combat veterans with an adverse impact in multiple important life domains. OBJECTIVES: We updated and evaluated the evidence examining the psychosocial impact of combat-related emotional numbing, including ethnoracial and gender differences. METHOD: We reviewed 1,209 articles published betwen January 2012 and 2018 and selected 24 studies for inclusion. We assessed the overall study quality as fair using a national quality assessment tool. RESULTS: Studies found emotional numbing to wield adverse effects in the areas of symptom nonimprovement, mental health difficulties, increased service utilization, poor relationship functioning, reduced quality of life, substance use disorders, suicidality, and aggression/violence. We also found evidence of ethnoracial and gender differences in veterans' posttraumatic stress disorder-related emotional numbing symptoms. CONCLUSION: Clinicians should incorporate findings on emotional numbing into assessment, treatment planning, and monitoring, to improve treatment retention and psychosocial outcomes. Implications for ethnoracial and gender differences require further exploration.

Pilot Study of a Single Session Heart Rate Variability Biofeedback Intervention on Veterans' Posttraumatic Stress Symptoms.

Veterans with posttraumatic stress symptoms exhibit reduced heart rate variability characteristic of autonomic nervous system dysregulation. Studies show heart rate variability biofeedback (HRVB) is effective in reducing posttraumatic stress symptoms by improving autonomic functioning. Participants in this pilot study were veterans of different war eras with military-related posttraumatic stress symptoms. The study aims were to examine the impact of a single session HRVB intervention on posttraumatic stress symptoms and heart rate variability, test persistence of effects, and determine if veterans would find the intervention acceptable. One group (n = 6) received training in diaphragmatic breathing and heart rate variability biofeedback, augmented by twice-daily practice using a smart phone and breath pacing app. A second group (n = 6) received only a single session of diaphragmatic breathing training. After 4 weeks, participants in the second group (n = 5) received the full intervention. HRVB significantly reduced global posttraumatic stress symptoms, whereas diaphragmatic breathing alone did not. Further, veterans found the approach acceptable, as demonstrated by a high degree of adherence with prescribed practice, low study attrition, and continued use over time. Results of this pilot study warrant further refinement of a protocol utilizing mHealth to treat posttraumatic stress symptoms in military populations.
