Prevalence and Co-Occurrence of Psychiatric Conditions Among Bereaved Adults.

Importance: Rates of grief-related psychiatric conditions, such as prolonged grief disorder (PGD), posttraumatic stress disorder (PTSD), and major depressive disorder (MDD), among bereaved adults in the US are largely unknown due to limited studies that leverage national samples. Objective: To assess risk factors for and prevalence rates and co-occurrence of PGD, PTSD, and MDD among bereaved adults in the US. Design, Setting, and Participants: Data for this survey study were collected from a large US panel sample between October 10 and 28, 2022, using a web-based survey. Participants were aged 18 years or older and were proficient in English. Data analysis was conducted between March and June 2023. Main Outcomes and Measures: Probable psychiatric conditions were assessed with validated measures that used conservative cutoff scores, duration, and impairment criteria. These measures included the revised Prolonged Grief Disorder scale for PGD, the PTSD Checklist for DSM-5 for PTSD, and the Patient Health Questionnaire-9 for MDD. Data were analyzed using basic descriptives and logistic regression. Results: A total of 2034 adults (n = 1529 and 505 in the bereaved and comparison groups, respectively) completed the study. Respondents had a mean (SD) age of 40.7 (15.9) years; the majority were women (1314 [64.6%]) and had at least some college experience (1394 [68.5%]). With regard to race and ethnicity, 392 respondents (19.3%) were Black, 138 (6.8%) were Hispanic, and 1357 (66.7%) were White. Among bereaved adults, 312 (20.4%), 518 (33.9%), and 461 (30.2%) met criteria for a presumptive diagnosis of PGD, PTSD, and MDD, respectively. Comorbidities were common, with 441 participants (28.8%) meeting criteria for at least 2 co-occurring disorders. Comorbid PGD, PTSD, and MDD were more common than any 2 co-occurring or isolated disorders; the presence of co-occurring conditions was more likely among respondents who reported a traumatic loss. Age and educational attainment were associated with the risk of psychiatric conditions; less time since the index death, loss of a psychologically close other, and a traumatic loss experience were associated with increased risk of PGD, PTSD, and MDD or their co-occurrence. Conclusions and Relevance: In this study, the majority of bereaved adults did not meet presumptive criteria for PGD, PTSD, or MDD. Nevertheless, PGD, PTSD, and MDD were highly prevalent and comorbid, particularly among those who experienced traumatic loss. These findings underscore the need for integrated psychological care that leverages transdiagnostic mechanisms of evidence-based practice.

Examining the Associations Between Substance Misuse and Suicide Bereavement.

Focusing on the understudied question of substance misuse among suicide bereaved adults we investigated patterns of binge drinking and non-prescribed drug use among a recently bereaved sample (n = 1,132). Comparing our respondents to the non-bereaved, those in the 2022 National Survey of Drug Use and Health (n = 71,369), we did not find heightened problematical substance misuses among our respondents. With t-tests and multiple regression analyses we examined whether binge drinkers and non-prescribed drug users had heightened levels of grief difficulties, PTSD, self-blaming and depression compared to others not bingeing or using non-prescribed drugs. Results showed binge drinkers had more of all these grieving problems when important confounding variables were also considered. Analysis of the demographic correlates of bingeing showed them dimly aware of their own additional grieving and substance misusing problems. Since 75% indicated being under the care of counseling professionals, this represents an important opportunity for psycho-educational helping.

Interventions for adult survivors of intrafamilial homicide: A review of the literature.

Individuals bereaved by intrafamilial homicide, in which the perpetrator and decedent were both members of the same family, experience an elevated risk for risk for mental health complications. Given the contextual complexity of intrafamilial homicide (IFH) and the negative sequalae this form of loss can engender, psychological interventions may assist survivors with adjustment on a number of fronts. This scoping review therefore addresses an important knowledge gap by summarizing the limited information on interventions specific to intrafamilial homicide survivors. Results failed to identify interventions specific to IFH bereavement, though interventions that may be deemed appropriate are highlighted and described. As such, this scoping review provides a practical synthesis of evidence-based and evidence-informed psychological interventions for traumatic loss that are applicable to and may hold promise for this vulnerable population. Recommendations for future research and best practices with intrafamilial homicide survivors are also discussed.

Predictors of Stigma, Guilt, and Shame among Adults Bereaved by Fatal Overdose.

With the spectacular rise of US overdose deaths, bereavement for these affected families has become a matter of increasing concern. Qualitative research has highlighted the role of stigmatization as well as guilt and shame among this population. However, the magnitude and pre-death predictors of stigmatization, guilt, and shame have yet to be assessed quantitatively. In the current study, we assess the magnitude of stigmatization, guilt, and shame among 115 adults bereaved by overdose by drawing comparisons with 185 adults bereaved by suicide. Results revealed no significant differences regarding overall levels of stigmatization, guilt, and shame between the overdose and suicide bereaved. Among the overdose bereaved, regression models indicated a number of pre-death factors associated with stigmatization, guilt, and shame, such as the frequency of the decedent's drug use, family drug use severity, and interpersonal conflict between the bereaved and the decedent. Implications and future directions for research are discussed.

Personality and Grief-Related Panic Attacks: Analysis of Neuroticism, Worry, and Anxiety Sensitivity.

Grief-related panic attacks (GRPAs) are a relatively common yet debilitating psychological reaction to loss, the mechanisms of which remain poorly understood among scholars. The purpose of this study was to identify the personality traits that underlie GRPAs in a sample of 314 bereaved adults. The results indicate that GRPAs were relatively common (55.4%) and that anxiety sensitivity uniquely predicted both frequency and impairment associated with these kinds of attacks, while taking into account the effects of neuroticism, trait worry, grief, and gender. Findings suggest that anxiety sensitivity may be a risk factor for GRPAs and magnified grief for some mourners. Clinical implications and future directions are discussed.

Examining grieving problem correlates of anticipation of the death vs. shock among overdose death and suicide bereaved adults.

We conducted an online survey with individuals bereaved by drug deaths (n = 115), suicide (n = 185) and sudden natural deaths (n = 103), including questions about anticipating the death vs. shock, other behaviors, established measures of mental health and grieving difficulties. Results showed more drug death bereaved anticipating their loved one's death while suicide bereaved were more shocked. Death shocked respondents showed greater PTSD, other mental health, and grieving problems; those anticipating the death had less PTSD, grieving problems, and engaged in more meaning-making. These contrasting patterns should call for diverging clinical strategies in offering aid to these traumatically bereaved mourners.

Bereavement in the Aftermath of Suicide, Overdose, and Sudden-Natural Death: Evaluating a New Measure of Needs.

Bereavement has been associated with a number of adverse outcomes, including mortality, particularly among those who experience the sudden loss of a close other. With rising rates of sudden death in the United States, fueled by an alarming increase in fatal overdose deaths, identifying bereavement-related needs among the sudden-death bereaved is essential. The present study investigated the factor structure, internal reliability, and validity of the Sudden Bereavement Needs Inventory (SBNI) in a sample of sudden loss survivors (i.e., fatal overdose, suicide, and sudden-natural loss; N = 403). Confirmatory factor analysis supported a six-factor structure, with items reflecting pragmatic, informational, spiritual, relational, meaning, and emotional needs. SBNI factors showed adequate internal consistency, with significant associations between SBNI scores, loss characteristics, and mental health outcomes (e.g., prolonged grief symptoms, meaning-making, posttraumatic stress disorder [PTSD] symptoms, and anxiety), supporting the scale's validity and highlighting the potential applicability of the instrument in both research and clinical contexts. Future research should examine test-retest reliability of the SBNI, particularly through the lens of understanding whether and how bereavement needs change over time.

Exploring the mental health correlates of overdose loss.

Despite the exorbitant rise in overdose-related deaths, little is known about the mental health burden associated with this form of loss. Using validated self-report instruments, the present study investigated the prevalence of pathological symptoms of prolonged grief disorder (PGD), posttraumatic stress disorder (PTSD), major depressive disorder (MDD) and generalized anxiety disorder (GAD), and suicide risk among a sample of overdose loss survivors (n = 115). Comparison groups consisting of other sudden loss survivors (suicide and sudden-natural loss) were employed to illuminate any shared or unique mental health challenges. Consistent with this study's primary hypothesis, results indicated that the overall mental health burden of overdose loss is substantial. Specifically, after controlling for a number of covariates, overdose loss survivors were approximately three times more likely to meet the symptom severity threshold for PGD, PTSD, and MDD compared to sudden-natural loss survivors. Overdose loss survivors also appeared to be at risk for GAD symptoms and suicide, but differences were non-significant after accounting for a number of covariates. Overall, this study is the first to examine this particular constellation of mental health outcomes associated with overdose bereavement, underscoring the need for additional empirical and clinical attention placed on this burgeoning population.

Grief memoirs: The familiarity of helping professionals with the genre and its potential incorporation into grief therapy.

The grief memoir is a fast-developing genre that in recent decades has become a popular form of public mourning and self-therapy in many Western cultures, especially in the United States and Great Britain. We surveyed 76 helping professionals to assess if the grief memoir is a genre with which they are familiar and whether they employ such narratives as an adjunct in their work with the bereaved. Most bibliotherapeutic studies focus either on self-help or affective literature. This study is unique in evaluating a life writing genre which promises to combine the therapeutic benefits of both.

Examining bereavement-related needs and outcomes among survivors of sudden loss: A latent profile analysis.

OBJECTIVE: Recognizing important bereavement-related needs among sudden loss survivors (e.g., suicide, overdose)-a population that is burgeoning and at risk for deleterious outcomes-is a critical task as needs may reflect modifiable grief-related variables that can assist with post-loss adjustment. METHODS: Latent profile analysis was used among 347 sudden loss survivors to (a) identify distinct patterns of needs among survivors of sudden loss, (b) assess predictors of such profiles, and (c) investigate differences in profiles in terms of bereavement outcomes. RESULTS: Four classes of bereavement-related needs were identified: a low needs class, a moderate needs-spiritual class, a moderate needs-relational class, and a high needs (HN) class. Clear differences emerged between need classes with the HN class evidencing the greatest level of grief and mental health sequelae. CONCLUSION: Tending to bereavement-related needs is critical, as they indicate the degree of distress and reflect modifiable therapeutic variables.

Spirituality Influences Emotion Regulation During Grief Talk: The Moderating Role of Prolonged Grief Symptomatology.

A growing body of research demonstrates that religion greatly affects people's adjustment to loss. However, little is known about the influence of religiosity on emotion regulation during grief. The present study attempts to fill this void in the literature by examining the predictive relationship between variables assessing facets of religiosity and emotion regulation during an interview about loss in a sample of bereaved adults. The results demonstrated that religiousness, spirituality, and negative religious coping were correlated with emotion reactivity following an interview. Spirituality's influence was also found to be moderated by prolonged grief symptoms, as spirituality predicted more adaptive emotion regulation among those with low-to-mild levels of prolonged grief symptomatology, but not among participants with elevated prolonged grief disorder (PGD) symptoms. These findings support the beneficial effects of religion in bereavement adjustment as well as its limits.

Investigating risk for grief severity: Attachment to the deceased and relationship quality.

Previous research examining the interrelationship between attachment, relationship quality, and bereavement outcomes suffers from a lack of precision and sophistication in the measurement of the core constructs of interest. The present study adapted an existing measure of attachment and employed a novel instrument of relationship quality to examine specific attachment to and relationship quality with the deceased as contributors to grief symptom severity. A sample of 385 bereaved college students completed measures retrospectively assessing relationship quality, attachment to the deceased, and grief symptomatology. Findings indicate that specific attachment to the deceased differs significantly from global attachment style and that relationship quality and attachment anxiety and avoidance interact in significant ways to predict the risk of grief severity. Specifically, individuals with a Preoccupied attachment style (high anxiety, low avoidance) are most at risk for adverse grief reactions in the context of high relationship closeness and conflict. This study is limited by an over-representation of extended family loss, which may have unique implications for attachment and relationship quality. Grief therapists should consider the implications of attachment and relationship quality with the deceased in the selection of relationship-enhancing or relational problem-solving interventions.

Closeness and Conflict With the Deceased: Exploring the Factor Structure of the Quality of Relationships Inventory in a Bereaved Student Sample.

With mounting empirical evidence that interpersonal closeness and conflict with the deceased prior to death are significant predictors of grief reactions following loss, accurate empirical examination of these two constructs is of high importance. Despite the utility of the Quality of Relationships Inventory (QRI) in numerous domains of research, the original instrument was not constructed with a predeath, mourner-decedent relationship in mind. Therefore, this study clarified the factor structure of a modified QRI focusing on major dimensions of the predeath relationship with the deceased-dynamics that could have strong implications for the survivor's bereavement trajectory. An exploratory factor analysis of 386 bereaved adults revealed two salient factors, deemed closeness and conflict. These results suggest that the modified bereavement version of the QRI, designated the Quality of Relationships Inventory-Bereavement version, is well positioned to advance research in thanatology, with possible limitations noted in the range of relationships to which it is applicable.

Management of calciphylaxis in a burn center: A case series and review of the literature.

Calciphylaxis is a rare, necrotizing skin disorder usually associated with kidney disease, but also caused by many other systemic illnesses. This disease is associated with mortality rates as high as 80% at 1year. We present the demographic and clinical data of nine patients with calciphylaxis treated at our burn center over a 10year period. We review the literature on the clinical presentation, pathophysiology, diagnosis and treatment of this rare disease. We propose that these patients be treated similar to patients with thermal burn injury; meaning intensive wound care, surgical management, critical care and physical therapy. Burn centers are uniquely capable of caring for these incredibly complex patients due to their experience in managing patients with extensive skin and soft tissue defects, wounds and diseases.

Distinguishing the meaning making processes of survivors of suicide loss: An expansion of the meaning of loss codebook.

Suicide loss represents particularly a difficult form of bereavement due to the challenges that volitional death poses to survivors. Understanding these challenges requires recognition of the idiosyncratic processes of meaning reconstruction for this specific group of grievers. The current study investigates such processes in survivors of suicide loss (SOSL) by utilizing the Meaning of Loss Codebook (MLC) to analyze the narratives of eight SOSL. The findings contribute to a broader understanding of meaning making following suicide, strengthen the validity of the MLC by demonstrating its appropriateness for SOSL, and illuminate unique challenges faced by SOSL, resulting in the proposal of supplemental MLC codes. Research and clinical implications are discussed.

A concurrent examination of protective factors associated with resilience and posttraumatic growth following childhood victimization.

The present study concurrently examined protective factors associated with the adaptive outcomes of resilience and posttraumatic growth (PTG; defined as positive psychological change resulting from a life crisis or trauma), after accounting for relevant demographic factors and the impact of circumstances surrounding childhood victimization (i.e., age of first trauma, frequency of victimization, and perception of trauma severity). The protective factors examined in the present study included social support from friends and family, optimism, positive religious coping (i.e., looking to God for support and guidance; forgiveness), and negative religious coping (i.e., feeling abandoned by God; anger towards God). Participants included 161 college students from the US MidSouth, aged 18-24 (Mage = 19.97, SD = 1.86). All participants reported experiencing physical violence and/or sexual abuse during their childhood. Hierarchical multiple regression analyses indicated that after accounting for demographics and circumstances surrounding the childhood victimization, higher resilience was associated with greater family support, optimism, and positive religious coping, while higher posttraumatic growth was associated with greater optimism and positive religious coping. These findings underscore the protective role of optimism with respect to both resilience and posttraumatic growth. Additionally, results highlight the importance of examining cognitions related to religious coping rather than simply assessing broadband religiosity, as only positive religious coping was associated with adaptive outcomes. Findings suggest the importance of early intervention to bolster protective factors (i.e., family support, positive thinking, gratitude, and positive religious coping skills) among youth exposed to childhood physical and sexual victimization.

Mental Health Symptomatology and Exposure to Non-Fatal Suicidal Behavior: Factors That Predict Vulnerability and Resilience Among College Students.

Despite efforts to identify risk factors following exposure to completed suicide, research has paid less attention to the associations between exposure to non-fatal suicide behavior (NFSB) and mental health symptomatology-factors that may underlie one's susceptibility to future suicidal thoughts and behaviors. This study examined differences in mental health symptomatology among 192 college students exposed to NFSB and 202 exposed to general stressors. Results indicated that students exposed to NFSB had significantly higher levels of depression and anxiety compared to those exposed to a variety of other stressors but not NFSB. Furthermore, among those exposed, a number of risk and protective factors emerged in relation to psychological sequelae, such as emotional stability, social support, and the quality of the relationship between the exposed and suicidal individual. These findings highlight the importance of enhancing provisions of support for those exposed to NFSB.

Demonstration of sub-luminal propagation of single-cycle terahertz pulses for particle acceleration.

The sub-luminal phase velocity of electromagnetic waves in free space is generally unobtainable, being closely linked to forbidden faster than light group velocities. The requirement of sub-luminal phase-velocity in laser-driven particle acceleration schemes imposes a limit on the total acceleration achievable in free space, and necessitates the use of dispersive structures or waveguides for extending the field-particle interaction. We demonstrate a travelling source approach that overcomes the sub-luminal propagation limits. The approach exploits ultrafast optical sources with slow group velocity propagation, and a group-to-phase front conversion through nonlinear optical interaction. The concept is demonstrated with two terahertz generation processes, nonlinear optical rectification and current-surge rectification. We report measurements of longitudinally polarised single-cycle electric fields with phase and group velocity between 0.77c and 1.75c. The ability to scale to multi-megavolt-per-metre field strengths is demonstrated. Our approach paves the way towards the realisation of cheap and compact particle accelerators with femtosecond scale control of particles.Controlled generation of terahertz radiation with subluminal phase velocities is a key issue in laser-driven particle acceleration. Here, the authors demonstrate a travelling-source approach utilizing the group-to-phase front conversion to overcome the sub-luminal propagation limit.

Domains of Social Support That Predict Bereavement Distress Following Homicide Loss.

Psychological adaptation following homicide loss can prove more challenging for grievers than other types of losses. Although social support can be beneficial in bereavement, research is mixed in terms of identifying whether it serves as a buffer to distress following traumatic loss. In particular, studies have not parsed out specific domains of social support that best predict positive bereavement outcomes. Recruiting a sample of 47 African Americans bereaved by homicide, we examined six types of social support along with the griever's perceived need for or satisfaction with each and analyzed them in relation to depression, anxiety, complicated grief, and posttraumatic stress disorder outcomes. Results of multivariate analyses revealed that the griever's level of satisfaction with physical assistance at the initial assessment best predicted lower levels of depression, anxiety, and posttraumatic stress disorder levels 6 months later, while less need for physical assistance predicted lower complicated grief at follow-up. Clinical implications and suggestions for future research are discussed.
