Prevalence, Correlates, and Psychiatric Burden of Prolonged Grief Disorder in U.S. Military Veterans: Results From a Nationally Representative Study.

OBJECTIVES: To examine the point prevalence and correlates of prolonged grief disorder (PGD) in a nationally-representative sample of United States (U.S.) veterans. METHODS: Data were analyzed from the National Health and Resilience in Veterans Study, a nationally representative study of 2,441 U.S. veterans. RESULTS: A total of 158 (weighted 7.3%) veterans screened positive for PGD. The strongest correlates of PGD were adverse childhood experiences, female sex, non-natural causes of death, knowing someone who died from coronavirus disease 2019, and number of close losses. After adjusting for sociodemographic, military, and trauma variables, veterans with PGD were 5-to-9 times more likely to screen positive for post-traumatic stress disorder, major depressive disorder, and generalized anxiety disorder. After additional adjustment for current psychiatric and substance use disorders, they were 2-3 times more likely to endorse suicidal thoughts and behaviors. CONCLUSIONS: Results underscore the importance of targeting PGD as an independent risk factor for psychiatric disorders and suicide risk.

Agreement in patient-therapist alliance ratings and its relation to dropout and outcome in a large sample of cognitive behavioral therapy for panic disorder.

Objective The therapeutic alliance is related to treatment outcome but less is known about the agreement on alliance between patients and therapists and its relationship to outcomes. We examined the association of patient-therapist congruence of alliance perceptions, early and late in cognitive behavioral therapy for panic disorder in relation to symptom reduction and dropout. Method: Patients (n = 181) and their therapists provided alliance ratings early and late during 11-session treatment. Independent evaluators rated patients' symptomatic levels post-treatment. Polynomial regression and response surface analysis were used to examine congruence as a predictor of outcome. Results: Early in therapy, stronger combined patient-therapist alliances, regardless of agreement, predicted lower symptom severity at the end of therapy and a lower likelihood of dropout. Late in treatment, the outcome was worse when therapist ratings of the alliance were higher than those of the patient. Conclusions: Therapist-patient agreement on the strength of the alliance is important for symptom improvement and dropout. The study highlights the importance of understanding the dyadic nature of the alliance and its impact on therapeutic change.

Adult separation anxiety disorder in complicated grief: an exploratory study on frequency and correlates.

INTRODUCTION: Complicated grief (CG) has been the subject of increasing attention in the past decades but its relationship with separation anxiety disorder (SEPAD) is still controversial. The aim of the current study was to explore the prevalence and clinical significance of adult SEPAD in a sample of help-seeking individuals with CG. METHODS: 151 adults with CG, enrolled in a randomized controlled trial comparing the effectiveness of (CG) treatment to that of interpersonal therapy, were assessed by means of the Inventory of Complicated Grief (ICG), the Structured Clinical Interview for DSM-IV, the Hamilton Rating Scale for Depression (HAM-D), the Work and Social Adjustment Scale (WSAS), the Adult Separation Anxiety Questionnaire (ASA-27), the Grief Related Avoidance Questionnaire (GRAQ), the Peritraumatic Dissociative Experiences Questionnaire (PDEQ), and the Impact of Events Scale (IES). RESULTS: 104 (68.9%) individuals with CG were considered to have SEPAD (ASA-27 score ≥22). Individuals with SEPAD were more likely to have reported a CG related to the loss of another close relative or friend (than a parent, spouse/partner or a child) (p=.02), as well as greater scores on the ICG (p=<.001), PDEQ (p=.004), GRAQ (p<.001), intrusion (p<.001) and avoidance (p=<.001) IES subscales, HAM-D (p<.001) and WSAS (p=.006). ASA-27 total scores correlated with ICG (p<.0001), PDEQ (p<.001) GRAQ (p<.0001) scores and both the IES intrusion (p<.0001) and IES avoidance (p<.0001) subscale scores. People with SEPAD had higher rates of lifetime post-traumatic stress disorder (PTSD) (p=.04) and panic disorder (PD) (p=.01). CONCLUSIONS: SEPAD is highly prevalent among patients with CG and is associated with greater symptom severity and impairment and greater comorbidity with PTSD and PD. Further studies will help to confirm and generalize our results and to determine whether adult SEPAD responds to CG treatment and/or moderates CG treatment response.

A note on a nonparametric regression test through penalized splines.

We examine a test of a nonparametric regression function based on penalized spline smoothing. We show that, similarly to a penalized spline estimator, the asymptotic power of the penalized spline test falls into a small- K or a large-K scenarios characterized by the number of knots K and the smoothing parameter. However, the optimal rate of K and the smoothing parameter maximizing power for testing is different from the optimal rate minimizing the mean squared error for estimation. Our investigation reveals that compared to estimation, some under-smoothing may be desirable for the testing problems. Furthermore, we compare the proposed test with the likelihood ratio test (LRT). We show that when the true function is more complicated, containing multiple modes, the test proposed here may have greater power than LRT. Finally, we investigate the properties of the test through simulations and apply it to two data examples.

NIH Roundtable on Opportunities to Advance Research on Neurologic and Psychiatric Emergencies.

STUDY OBJECTIVE: The Institute of Medicine Committee on the Future of Emergency Care in the United States Health System (2003) identified a need to enhance the research base for emergency care. As a result, a National Institutes of Health (NIH) Task Force on Research in Emergency Medicine was formed to enhance NIH support for emergency care research. Members of the NIH Task Force and academic leaders in emergency care participated in 3 Roundtable discussions to prioritize current opportunities for enhancing and conducting emergency care research. We identify key research questions essential to advancing the science of emergency care and discuss the barriers and strategies to advance research by exploring the collaboration between NIH and the emergency care community. METHODS: Experts from emergency medicine, neurology, psychiatry, and public health assembled to review critical areas in need of investigation, current gaps in knowledge, barriers, and opportunities. Neurologic emergencies included cerebral resuscitation, pain, stroke, syncope, traumatic brain injury, and pregnancy. Mental health topics included suicide, agitation and delirium, substances, posttraumatic stress, violence, and bereavement. RESULTS: Presentations and group discussion firmly established the need for translational research to bring basic science concepts into the clinical arena. A coordinated continuum of the health care system that ensures rapid identification and stabilization and extends through discharge is necessary to maximize overall patient outcomes. There is a paucity of well-designed, focused research on diagnostic testing, clinical decisionmaking, and treatments in the emergency setting. Barriers include the limited number of experienced researchers in emergency medicine, limited dedicated research funding, and difficulties of conducting research in chaotic emergency environments stressed by crowding and limited resources. Several themes emerged during the course of the roundtable discussion, including the need for development of (1) a research infrastructure for the rapid identification, consent, and tracking of research subjects that incorporates innovative informatics technologies, essential for future research; (2) diagnostic strategies and tools necessary to understand key populations and the process of medical decisionmaking, including the investigation of the pathobiology of symptoms and symptom-oriented therapies; (3) collaborative research networks to provide unique opportunities to form partnerships, leverage patient cohorts and clinical and financial resources, and share data; (4) formal research training programs integral for creating new knowledge and advancing the science and practice of emergency medicine; and (5) recognition that emergency care is part of an integrated system from emergency medical services dispatch to discharge. The NIH Roundtable "Opportunities to Advance Research on Neurological and Psychiatric Emergencies" created a framework to guide future emergency medicine-based research initiatives. CONCLUSION: Emergency departments provide the portal of access to the health care system for most patients with acute neurologic and psychiatric illness. Emergency physicians and colleagues are primed to investigate neurologic and psychiatric emergencies that will directly improve the delivery of care and patient outcomes.

Mania Following Bereavement: State of the Art and Clinical Evidence.

Bereavement is the state of loss, determined in most of the cases by the death of a close person. It is probably the greatest sorrow that can occur in an individual life. Grief is a normal, healthy response to loss, evolving through stages in the process of mourning. In some cases, bereavement may lead to the outburst of manic episode: despite literature data being scarce, reports have explored this important clinical entity, variously called as "funeral mania" or "bereavement mania". We systematically reviewed the literature exploring the possible relationships between bereavement and the onset of a manic episode, both first or recurrent pre-existing episode, besides describing a case report on a manic episode in the aftermath of a loss event, with an accurate evaluation of prior mild mood spectrum instability, supporting the role of loss-events as potential risk factor for bipolar illness progression. This article tries summarizing existing evidence on the debate whether clinicians should consider mania as a possible bereavement reaction.

Does attachment avoidance help people cope with loss? The moderating effects of relationship quality.

Previous research has been inconsistent about the role of attachment avoidance in coping with loss. The present study sought to resolve this issue by examining the potential moderating role of relationship quality with the deceased. The authors used longitudinal data on bereaved spouses (N=50) collected at 4 and 18 months postloss. Three-way effects emerged among attachment avoidance, attachment anxiety, and marital quality in the prediction of complicated grief (CG) symptoms at 18 months, controlling for 4-month symptoms. Findings indicated that, in the context of high but not low marital quality, persons with a dismissingly avoidant attachment style (high avoidance, low anxiety) experienced marked reductions in CG symptoms from 4 to 18 months. Findings clarify the role of attachment avoidance in coping with loss and underscore that relationship quality is a critical factor in the attachment-grief relationship.

Accommodating Grief on Twitter: An Analysis of Expressions of Grief Among Gang Involved Youth on Twitter Using Qualitative Analysis and Natural Language Processing.

There is a dearth of research investigating youths' experience of grief and mourning after the death of close friends or family. Even less research has explored the question of how youth use social media sites to engage in the grieving process. This study employs qualitative analysis and natural language processing to examine tweets that follow 2 deaths. First, we conducted a close textual read on a sample of tweets by Gakirah Barnes, a gang-involved teenaged girl in Chicago, and members of her Twitter network, over a 19-day period in 2014 during which 2 significant deaths occurred: that of Raason "Lil B" Shaw and Gakirah's own death. We leverage the grief literature to understand the way Gakirah and her peers express thoughts, feelings, and behaviors at the time of these deaths. We also present and explain the rich and complex style of online communication among gang-involved youth, one that has been overlooked in prior research. Next, we overview the natural language processing output for expressions of loss and grief in our data set based on qualitative findings and present an error analysis on its output for grief. We conclude with a call for interdisciplinary research that analyzes online and offline behaviors to help understand physical and emotional violence and other problematic behaviors prevalent among marginalized communities.

The epidemiology of panic attacks, panic disorder, and agoraphobia in the National Comorbidity Survey Replication.

CONTEXT: Only limited information exists about the epidemiology of DSM-IV panic attacks (PAs) and panic disorder (PD). OBJECTIVE: To present nationally representative data about the epidemiology of PAs and PD with or without agoraphobia (AG) on the basis of the US National Comorbidity Survey Replication findings. DESIGN AND SETTING: Nationally representative face-to-face household survey conducted using the fully structured World Health Organization Composite International Diagnostic Interview. PARTICIPANTS: English-speaking respondents (N=9282) 18 years or older. MAIN OUTCOME MEASURES: Respondents who met DSM-IV lifetime criteria for PAs and PD with and without AG. RESULTS: Lifetime prevalence estimates are 22.7% for isolated panic without AG (PA only), 0.8% for PA with AG without PD (PA-AG), 3.7% for PD without AG (PD only), and 1.1% for PD with AG (PD-AG). Persistence, lifetime number of attacks, and number of years with attacks increase monotonically across these 4 subgroups. All 4 subgroups are significantly comorbid with other lifetime DSM-IV disorders, with the highest odds for PD-AG and the lowest for PA only. Scores on the Panic Disorder Severity Scale are also highest for PD-AG (86.3% moderate or severe) and lowest for PA only (6.7% moderate or severe). Agoraphobia is associated with substantial severity, impairment, and comorbidity. Lifetime treatment is high (from 96.1% for PD-AG to 61.1% for PA only), but 12-month treatment meeting published treatment guidelines is low (from 54.9% for PD-AG to 18.2% for PA only). CONCLUSION: Although the major societal burden of panic is caused by PD and PA-AG, isolated PAs also have high prevalence and meaningful role impairment.

Prevalence and correlates of estimated DSM-IV child and adult separation anxiety disorder in the National Comorbidity Survey Replication.

OBJECTIVE: Despite its inclusion in DSM-IV, little is known about the prevalence or correlates of adult separation anxiety disorder or its relationship to the childhood disorder. Results of the first epidemiological study of adult separation anxiety disorder, to the authors' knowledge, and its relationship to childhood separation anxiety disorder are presented. METHOD: Data were from the National Comorbidity Survey Replication (NCS-R), a nationally representative survey of U.S. households. A fully structured, lay-administered diagnostic interview assessed a wide range of DSM-IV disorders, including separation anxiety disorder. No independent clinical validation was obtained of the assessment. RESULTS: Lifetime prevalence estimates of childhood and adult separation anxiety disorders were 4.1% and 6.6%, respectively. Approximately one-third of the respondents who were classified as childhood cases (36.1%) had an illness that persisted into adulthood, although the majority classified as adult cases (77.5%) had first onset in adulthood. The assessment of separation anxiety disorder in the NCS-R was comorbid with other NCS-R or DSM-IV disorders and associated with severe role impairment in roughly half of the comorbid cases and one-fourth of the pure cases. The majority of people with estimated adult separation anxiety disorder are untreated, even though many obtain treatment for comorbid conditions. CONCLUSIONS: Criteria for adult separation anxiety disorder should be refined in future editions of DSM because the disorder is likely to be much more common in adults than previously recognized. Research is needed to develop and evaluate treatments that take into consideration its high comorbidity with other DSM-IV disorders.

Treating complicated grief and substance use disorders: a pilot study.

Empirically supported treatments for co-occurring substance use disorders (SUDs) and grief problems are lacking, despite the salience of grief pathology in substance abusers. Identification of a syndrome of complicated grief, distinct from bereavement-related depression and anxiety, led to the development of a targeted treatment, but this treatment has not been tried with persons with SUDs. We recruited 16 adults with complicated grief and substance dependence or abuse into an open pilot study of a manualized 24-session treatment, incorporating motivational interviewing and emotion coping and communication skills into our efficacious complicated grief treatment. Completer and intent-to-treat analyses showed significant reductions in Inventory of Complicated Grief and Beck Depression Inventory scores, with large effect sizes. Timeline Followback percent days abstinent increased significantly in both analyses, with medium to large effect sizes, and cravings declined significantly. Study limitations notwithstanding, complicated grief and substance use treatment appears to be a promising intervention that merits further research.

Screening for complicated grief among Project Liberty service recipients 18 months after September 11, 2001.

OBJECTIVE: The authors surveyed a sample of Project Liberty crisis counseling recipients approximately 1.5 years after the terrorist attacks on September 11, 2001, to determine the proportion of respondents who screened positive for complicated grief, a recently identified condition marked by symptoms of continuing separation distress and accompanying bereavement-related traumatic distress. METHODS: A total of 149 service recipients drawn from eight high-volume providers responded to a telephone survey that included questions to screen for complicated grief. RESULTS: Approximately half of the recipients knew someone who had been killed in the attacks. Of those recipients, 44 percent screened positive for complicated grief. Individuals who lost a family member were more likely than those who lost an acquaintance to screen positive for complicated grief. Positive screens were associated with functional impairment independent of the presence of symptoms consistent with full or subthreshold major depression or posttraumatic stress disorder (PTSD). Thirty-two percent of those who screened positive for complicated grief did not meet even subthreshold criteria for major depression or PTSD. CONCLUSIONS: Results affirmed the importance of complicated grief as a unique condition and indicated the need to attend to the psychological consequences of bereavement in disaster-related mental health services.

Outcomes of enhanced counseling services provided to adults through Project Liberty.

OBJECTIVE: Project Liberty provided brief crisis counseling to 753,015 residents of New York City and surrounding counties after the attacks on the World Trade Center. Most regained predisaster functioning after counseling. For those who did not, Project Liberty provided enhanced services by specially trained, licensed mental health professionals. Individuals receiving crisis counseling and enhanced services responded to confidential telephone interviews about 18 and 24 months, respectively, after the attacks. Impairment was compared between groups to determine whether enhanced services recipients reported improved functioning and fewer symptoms of depression, posttraumatic stress, and complicated grief. METHODS: Crisis counseling recipients (N=153) were interviewed once and enhanced services recipients (N=76) were interviewed twice about symptomatology and daily functioning. RESULTS: The samples did not differ in age or gender. Significantly greater proportions of enhanced services recipients reported knowing someone who died as a result of the attacks, having been involved in rescue efforts, or having lost their job because of the attacks. Compared with crisis counseling respondents, enhanced services recipients at their first interview reported significantly more symptoms of depression, grief, and traumatic stress and significantly poorer daily functioning in five life areas. At follow-up, enhanced services respondents reported significant improvement in three of five functioning domains, significantly fewer symptoms of depression and grief, and marginally less traumatic stress. CONCLUSIONS: Recipients of enhanced services were more impaired than people who received only crisis counseling. On the basis of reports from service recipients, meaningful improvements in functioning and symptoms may be associated with the receipt of enhanced services.

Use of clients' self-reports to monitor Project Liberty clinicians' fidelity to a cognitive-behavioral intervention.

OBJECTIVE: This study examined outcomes associated with clinicians' fidelity to key elements of a cognitive-behavioral treatment intervention developed for Project Liberty's enhanced services counseling program. METHODS: In telephone interviews 60 individuals reported how often their clinicians provided six components considered central to the intervention by the intervention developers. Respondents received services at sites where some (25 to 50 percent) or all clinicians had received training in the intervention. RESULTS: Compared with respondents who received services where only some clinicians had received training (N=19), those who received services where all clinicians had received training (N=41) were significantly more likely to report that their clinicians applied techniques central to the intervention (p<.01). Additionally, those who received services from sites where all clinicians were trained were significantly more likely to report that they had been given homework (p<.05). CONCLUSIONS: Brief questions to service recipients are a useful and cost-effective way to monitor intervention fidelity.

The road back: predictors of regaining preattack functioning among Project Liberty clients.

OBJECTIVES: This study determined the likelihood and predictors of Project Liberty counseling recipients' reporting their return to satisfactory life functioning 16 to 26 months after the September 11, 2001, attacks. METHODS: Using anonymous brief paper-and-pencil questionnaires or structured telephone interviews, 452 respondents provided retrospective ratings of their functioning in five life domains during the month before the World Trade Center attacks and the month immediately before the assessment. Information on demographic characteristics and exposure to risk during the World Trade Center attacks also was obtained and used in logistic regression models. The 153 respondents who were interviewed by telephone also rated helpfulness of various coping strategies. RESULTS: In the five domains, 77 to 87 percent of the sample reported good to excellent functioning in the month before the attacks; 55 to 68 percent reported returning to at least the same level of daily functioning after the attacks. African Americans were two to four times more likely than respondents of all other races to report a return to good or excellent functioning after the attack in four domains. Compared with respondents who did not lose their job as a result of the attacks, those who did lose their job were less likely to return to good preattack functioning in two domains. Project Liberty counseling reportedly helped 90 percent of respondents return to predisaster levels of functioning. CONCLUSIONS: Responses to future terrorist attacks should consider demographic characteristics and the impact of the attack because they can affect return to preattack functioning. Counselors should support activities that facilitate positive responses and ameliorate negative psychological responses.

Treatment of complicated grief: a randomized controlled trial.

CONTEXT: Complicated grief is a debilitating disorder associated with important negative health consequences, but the results of existing treatments for it have been disappointing. OBJECTIVE: To compare the efficacy of a novel approach, complicated grief treatment, with a standard psychotherapy (interpersonal psychotherapy). DESIGN: Two-cell, prospective, randomized controlled clinical trial, stratified by manner of death of loved one and treatment site. SETTING: A university-based psychiatric research clinic as well as a satellite clinic in a low-income African American community between April 2001 and April 2004. PARTICIPANTS: A total of 83 women and 12 men aged 18 to 85 years recruited through professional referral, self-referral, and media announcements who met criteria for complicated grief. INTERVENTIONS: Participants were randomly assigned to receive interpersonal psychotherapy (n = 46) or complicated grief treatment (n = 49); both were administered in 16 sessions during an average interval of 19 weeks per participant. MAIN OUTCOME MEASURE: Treatment response, defined either as independent evaluator-rated Clinical Global Improvement score of 1 or 2 or as time to a 20-point or better improvement in the self-reported Inventory of Complicated Grief. RESULTS: Both treatments produced improvement in complicated grief symptoms. The response rate was greater for complicated grief treatment (51%) than for interpersonal psychotherapy (28%; P = .02) and time to response was faster for complicated grief treatment (P = .02). The number needed to treat was 4.3. CONCLUSION: Complicated grief treatment is an improved treatment over interpersonal psychotherapy, showing higher response rates and faster time to response.

Computerized adaptive measurement of depression: a simulation study.

BACKGROUND: Efficient, accurate instruments for measuring depression are increasingly important in clinical practice. We developed a computerized adaptive version of the Beck Depression Inventory (BDI). We examined its efficiency and its usefulness in identifying Major Depressive Episodes (MDE) and in measuring depression severity. METHODS: Subjects were 744 participants in research studies in which each subject completed both the BDI and the SCID. In addition, 285 patients completed the Hamilton Depression Rating Scale. RESULTS: The adaptive BDI had an AUC as an indicator of a SCID diagnosis of MDE of 88%, equivalent to the full BDI. The adaptive BDI asked fewer questions than the full BDI (5.6 versus 21 items). The adaptive latent depression score correlated r =.92 with the BDI total score and the latent depression score correlated more highly with the Hamilton (r =.74) than the BDI total score did (r =.70). CONCLUSIONS: Adaptive testing for depression may provide greatly increased efficiency without loss of accuracy in identifying MDE or in measuring depression severity.

The relationships among separation anxiety disorder, adult attachment style and agoraphobia in patients with panic disorder.

Epidemiological studies indicate that separation anxiety disorder occurs more frequently in adults than children. It is unclear whether the presence of adult separation anxiety disorder (ASAD) is a manifestation of anxious attachment, or a form of agoraphobia, or a specific condition with clinically significant consequences. We conducted a study to examine these questions. A sample of 141 adult outpatients with panic disorder participated in the study. Participants completed standardized measures of separation anxiety, attachment style, agoraphobia, panic disorder severity and quality of life. Patients with ASAD (49.5% of our sample) had greater panic symptom severity and more impairment in quality of life than those without separation anxiety. We found a greater rate of symptoms suggestive of anxious attachment among panic patients with ASAD compared to those without ASAD. However, the relationship between ASAD and attachment style is not strong, and adult ASAD occurs in some patients who report secure attachment style. Similarly, there is little evidence for the idea that separation anxiety disorder is a form of agoraphobia. Factor analysis shows clear differentiation of agoraphobic and separation anxiety symptoms. Our data corroborate the notion that ASAD is a distinct condition associated with impairment in quality of life and needs to be better recognized and treated in patients with panic disorder.

Dream content in complicated grief: a window into loss-related cognitive schemas.

Bereavement and its accompanying psychological response (grief) constitute potent experiences that necessitate the reorganization of cognitive-affective representations of lost significant attachment figures during both wakefulness and dreaming. The goals of this preliminary study were to explore whether the dream content of 77 adults with complicated grief (CG) differed from that of a normative sample and whether CG patients who dream of the deceased differ from CG patients who do not dream of the deceased on measures of daytime emotional distress. CG dreams were characterized by more family and familiar characters including the deceased (in women), and fewer social interactions and emotions compared to norms. Increased representations of familiar characters in CG dreams may reflect attempts to reorganize relational cognitive schemas to compensate for the loss.
