Impact of concurrent naturalistic pharmacotherapy on psychotherapy of complicated grief

Prolonged Grief Disorder: Course, Diagnosis, Assessment, and Treatment

Losing a loved one is one of life's greatest stressors. Although most bereaved individuals navigate through a period of intense acute grief that lessens with time, approximately 10% will develop a prolonged grief condition. This review provides an overview of the course of grief and describes risk factors for developing prolonged grief disorder. The evolution of the prolonged grief disorder diagnosis, including the latest criteria sets for ICD-11 and DSM-5, as well as common comorbid conditions and differential diagnosis are discussed. Clinically useful self-report and clinician-rated measures for assessing symptom constructs and overall prolonged grief disorder severity, evidence-based psychotherapies (such as complicated grief treatment), as well as evidence about pharmacologic approaches are presented. Finally, the authors discuss important future directions, including a potential increase in prolonged grief disorder cases due to the COVID-19 pandemic.

Traumatic grief research and care in the aftermath of the COVID-19 pandemic

BACKGROUND

A significant increase in the number of individuals suffering from prolonged grief disorder is expected in the aftermath of the COVID-19 pandemic for two main reasons. First, the number of excess deaths has contributed to an immense number of bereaved individuals. Second, recent literature has shown that circumstances associated with COVID-19 deaths may be contributing to increased risk for the development of prolonged grief disorder.

OBJECTIVE

To best support those affected by loss during the COVID-19 pandemic, it is important to inform clinicians and researchers about the development, the nature and the treatment of prolonged grief disorder and employ sound research.

METHOD

In this editorial, we discuss important themes regarding prolonged grief disorder in the aftermath of the COVID-19 pandemic, to gather and present useful information for clinicians and researchers.

RESULTS

The following themes were addressed: 1. Harmonization in the diagnosis of prolonged grief disorder. 2. Screening tools and interventions. 3. Pharmacotherapy. 4. Special attention for the elderly. 5. Special attention for children and adolescents. 6. A causal system perspective for understanding grief and prolonged grief disorder.

CONCLUSIONS

If those involved in bereavement research and care manage to collaborate, the tragic consequences of COVID-19 might catalyse improvement of care for those most impaired following the loss of a loved one.

Effects of Mental Health Support on the Grief of Bereaved People Caused by Sewol Ferry Accident

Few studies have assessed the overall effects of multi-centered, complicated mental health support on the grief process. This study investigated the broader influence of mental health support provided practically to the bereaved family on the severity of complicated grief. Ninety-three bereaved family members of the Sewol ferry accident were recruited. Severity of complicated grief, post-traumatic stress disorder (PTSD) and depressive disorder was assessed through self-reporting questionnaire, inventory of complicated grief (ICG), PTSD Check List-5 (PCL-5) and Patient Health Questionnaire-9 (PHQ-9). We also included demographic, socioeconomic, health-related variables, and Functional Social Support Questionnaire (FSSQ), which affect the ICG score. Participants were divided into 4 groups based on the experience of psychotherapy or psychiatry clinic service before the accident and mental health support after the disaster. In univariate analysis, these 4 groups showed a significant difference in the mean ICG score (P = 0.020). Participants who received mental health support only after the Sewol ferry accident (group 2) showed a lower mean ICG score than those who received neither psychotherapy or psychiatry clinic service before the disaster nor mental health support after the accident (group 4). There was no significant correlation between the ICG score and other variables except for subjective health status measured 1 month after the disaster (P = 0.005). There was no significant difference in PCL-5 (P = 0.140) and PHQ-9 scores (P = 0.603) among groups, respectively. In conclusion, mental health support significantly reduced the severity of grief only in those participants who had not received any psychotherapy or psychiatry clinic service before the accident.

Mediators of Outcome in Complicated Grief Treatment

OBJECTIVE

In this study, we examined the mechanisms of action of complicated grief treatment (CGT), an efficacious psychotherapy for complicated grief.

METHOD

We explored 3 putative mediators (guilt/self-blame related to the deceased, negative thoughts about the future, and avoidance) among treatment completers assigned to either CGT (n = 35) or interpersonal psychotherapy (n = 34) in a previously reported randomized controlled trial. Antidepressant use was examined as a moderator of mediation effects.

RESULTS

A reduction in guilt/self-blame, negative thoughts about the future, and avoidance behavior each mediated the relationship between treatment group and complicated grief outcomes. Reduction in avoidance emerged as an independent mediator after controlling for all mediators.

CONCLUSION

Reducing avoidance of situations and emotions connected to the loss seems to be a key mechanism of change in CGT. Revising counterfactual thinking around troubling aspects of the death may also play a role in facilitating effective adaptation to loss.

Treatment for complicated grief: state of the science and ways forward

PURPOSE OF REVIEW

There is increasing recognition that a minority of bereaved persons experiences persistent and disabling grief symptoms, also termed complicated grief. We review currently proposed criteria for complicated grief in the Diagnostic and Statistical Manual of Mental Disorders (DSM 5) and the International Statistical Classification of Diseases and Related Health Problems (ICD-11), highlight controversies with regard to establishing complicated grief as a psychiatric disorder, summarize recent complicated grief treatment research within a cognitive behavioral treatment framework, and establish a novel and systematic research agenda for complicated grief treatment.

RECENT FINDINGS

Clinicians should be wary of overdiagnosis and misdiagnosis of complicated grief. Recent changes to definitions of complicated grief may threaten generalizability and clinical application of research findings. Universal treatment, treatment for at-risk groups and preventive complicated grief treatment appear ineffective. Although medication is often prescribed to bereaved persons, evidence for its effectiveness is equivocal. Face-to-face and internet-based cognitive behavioral therapy techniques appear most effective in targeting complicated grief. However, little is known about what, how, and for whom treatment works best.

SUMMARY

In light of these findings, we recommend systematic investigation of: what works best in complicated grief treatment, by conducting well designed, stepped effectiveness trials and treatment component dismantling studies; how it works, by conducting investigations on therapeutic theories and examining mediators of therapeutic change; and for whom it works, by examining potential moderators of treatment effects.

Optimizing Treatment of Complicated Grief: A Randomized Clinical Trial

IMPORTANCE

To our knowledge, this is the first placebo-controlled randomized clinical trial to evaluate the efficacy of antidepressant pharmacotherapy, with and without complicated grief psychotherapy, in the treatment of complicated grief.

OBJECTIVE

To confirm the efficacy of a targeted complicated grief treatment (CGT), determine whether citalopram (CIT) enhances CGT outcome, and examine CIT efficacy without CGT.

DESIGN, SETTING, AND PARTICIPANTS

Included in the study were 395 bereaved adults who met criteria for CG recruited from March 2010 to September 2014 from academic medical centers in Boston, Massachusetts; New York, New York; Pittsburgh, Pennsylvania; and San Diego, California. Co-occurring substance abuse, psychosis, mania, and cognitive impairment were exclusionary. Study participants were randomized using site-specific permuted blocks stratified by major depression into groups prescribed CIT (n = 101), placebo (PLA; n = 99), CGT with CIT (n = 99), and CGT with PLA (n = 96). Independent evaluators conducted monthly assessments for 20 weeks. Response rates were compared under the intention-to-treat principle, including all randomized participants in a logistic regression with inverse probability weighting.

INTERVENTIONS

All participants received protocolized pharmacotherapy optimized by flexible dosing, psychoeducation, grief monitoring, and encouragement to engage in activities. Half were also randomized to receive manualized CGT in 16 concurrent weekly sessions.

MAIN OUTCOMES AND MEASURES

Complicated grief-anchored Clinical Global Impression scale measurments every 4 weeks. Response was measured as a rating of "much improved" or "very much improved."

RESULTS

Of the 395 study participants, 308 (78.0%) were female and 325 (82.3%) were white. Participants' response to CGT with PLA vs PLA (82.5% vs 54.8%; relative risk [RR], 1.51; 95% CI, 1.16-1.95; P = .002; number needed to treat [NNT], 3.6) suggested the efficacy of CGT, and the addition of CIT did not significantly improve CGT outcome (CGT with CIT vs CGT with PLA: 83.7% vs 82.5%; RR, 1.01; 95% CI, 0.88-1.17; P = .84; NNT, 84). However, depressive symptoms decreased significantly more when CIT was added to treatment (CGT with CIT vs CGT with PLA: model-based adjusted mean [standard error] difference, -2.06 [1.00]; 95% CI, -4.02 to -0.11; P = .04). By contrast, adding CGT improved CIT outcome (CIT vs CGT with CIT: 69.3% vs 83.7%; RR, 1.21; 95% CI, 1.00-1.46; P = .05; NNT, 6.9). Last, participant response to CIT was not significantly different from PLA at week 12 (45.9% vs 37.9%; RR, 1.21; 95% CI, 0.82-1.81; P = .35; NNT, 12.4) or at week 20 (69.3% vs 54.8%; RR, 1.26; 95% CI, 0.95-1.68; P = .11; NNT, 6.9). Rates of suicidal ideation diminished to a substantially greater extent among participants receiving CGT than among those who did not.

CONCLUSIONS AND RELEVANCE

Complicated grief treatment is the treatment of choice for CG, and the addition of CIT optimizes the treatment of co-occurring depressive symptoms.

Efficacy of group psychotherapy for social anxiety disorder: A meta-analysis of randomized-controlled trials

Group psychotherapy for social anxiety disorder (SAD) is an established treatment supported by findings from primary studies and earlier meta-analyses. However, a comprehensive summary of the recent evidence is still pending. This meta-analysis investigates the efficacy of group psychotherapy for adult patients with SAD. A literature search identified 36 randomized-controlled trials examining 2171 patients. Available studies used mainly cognitive-behavioral group therapies (CBGT); therefore, quantitative analyses were done for CBGT. Medium to large positive effects emerged for wait list-controlled trials for specific symptomatology: g=0.84, 95% CI [0.72; 0.97] and general psychopathology: g=0.62, 95% CI [0.36; 0.89]. Group psychotherapy was also superior to common factor control conditions in alleviating symptoms of SAD, but not in improving general psychopathology. No differences appeared for direct comparisons of group psychotherapy and individual psychotherapy or pharmacotherapy. Hence, group psychotherapy for SAD is an efficacious treatment, equivalent to other treatment formats.

Assisting the bereaved: A systematic review of the evidence for grief counselling

BACKGROUND

Supporting people after bereavement is a priority area for many health services. Investment in bereavement care must be supported by a rigorous evidence-base.

AIM

To examine the (1) relative proportion of descriptive, measurement and intervention research in grief counselling and (2) quality and effectiveness of intervention studies.

DESIGN

Systematic review of studies published in the area of grief counselling.

DATA SOURCES

MEDLINE, Embase, Cochrane Library and PsycINFO databases were searched for studies published between 2000 and 2013. Eligible papers were categorised into descriptive, measurement, review, commentaries and intervention studies. Intervention studies were assessed against the Cochrane Effective Practice and Organisation of Care methodological criteria, and papers meeting criteria were assessed for quality. The impact of interventions on grief, psychological morbidity and quality of life was examined.

RESULTS

A total of 126 data-based papers, including 47 descriptive, 3 measurement and 76 grief counselling intervention studies were included. Only 59% (n = 45) of intervention studies met Effective Practice and Organisation of Care design criteria. Overall, study quality was poor, with the majority of interventions showing a risk of bias in several key areas. The three studies that met all criteria showed mixed effectiveness.

CONCLUSION

Grief counselling interventions require a strong rationale for design, and a systematic approach to development and evaluation. Descriptive research efforts should inform this process, focusing on homogeneity in sample, identification of risk factors for complicated grief and the impact of extraneous factors on intervention effects. Interventions should include comparisons to usual care, as well as replication to confirm positive findings.

Bereavement: course, consequences, and care

This paper discusses each of several potential consequences of bereavement. First, we describe ordinary grief, followed by a discussion of grief gone awry, or complicated grief (CG). Then, we cover other potential adverse outcomes of bereavement, each of which may contribute to, but are not identical with, CG: general medical comorbidity, mood disorders, post-traumatic stress disorder, anxiety, and substance use.

Treating complicated grief

IMPORTANCE

The death of a loved one is one of life's greatest, universal stressors to which most bereaved individuals successfully adapt without clinical intervention. For a minority of bereaved individuals, grief is complicated by superimposed problems and healing does not occur. The resulting syndrome of complicated grief causes substantial distress and functional impairment even years after a loss, yet knowing when and how to intervene can be a challenge.

OBJECTIVE

To discuss the differential diagnosis, risk factors for and management of complicated grief based on available evidence and clinical observations.

EVIDENCE REVIEW

MEDLINE was searched from January 1990 to October 2012. Additional citations were procured from references of select research and review articles. Available treatment studies targeting complicated grief were included.

RESULTS

A strong research literature led to inclusion of complicated grief in the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) (termed persistent complex bereavement disorder as a subtype of other specified trauma and stressor-related disorders), although it is a condition for which more research is formally recommended, and there is still ongoing discussion about the optimal name and diagnostic criteria for the disorder. Reliable screening instruments are available, and the estimated prevalence rate is 7% of bereaved people. Randomized controlled data support the efficacy of a targeted psychotherapy including elements that foster resolution of complicating problems and facilitate the natural healing process. Preliminary studies suggest antidepressant medications may be helpful.

CONCLUSION AND RELEVANCE

Individuals with complicated grief have greater risk of adverse health outcomes, should be diagnosed and assessed for suicide risk and comorbid conditions such as depression and posttraumatic stress disorder, and should be considered for treatment.

A Cognitive Attachment Model of prolonged grief: integrating attachments, memory, and identity

Prolonged grief (PG), otherwise known as complicated grief, has attracted much attention in recent years as a potentially debilitating condition that affects approximately 10% of bereaved people. We propose a model of PG that integrates processes of attachment, self-identity, and autobiographical memory. The paper commences with a discussion of the PG construct and reviews current evidence regarding the distinctiveness of PG from other bereavement related-outcomes. We then review the evidence regarding the dysfunctional attachments, appraisals, and coping styles that people with PG display. Recent evidence pertaining to the patterns of autobiographical memory in PG is described in the context of the self-memory system. This system provides a unifying framework to understand the roles of personal memories, identity, attachments, and coping responses in PG. The proposed model places emphasis on how one's sense of identity influences yearning, memories of the deceased, appraisals, and coping strategies, to maintain a focus on the loss. The model is discussed in relation to existing models of PG. The potential for shaping treatment strategies to shift perceptions of the self is then outlined. Finally, we outline future directions to test propositions stemming from the model and enhance our understanding of the mechanisms underlying PG.

Complicated grief in late life

Complicated grief (CG) is a syndrome that affects 10% to 20% of grievers regardless of age, although proportionally more will face the death of loved ones in late life, CG is characterized by preoccupying and disabling symptoms that can persist for decades such as an inability to accept the death, intense yearning or avoidance, frequent reveries, deep sadness, crying, somatic distress, social withdrawal, and suicidal ideation. This syndrome is distinct from major depression and post-traumatic stress disorder, but CG maybe comorbid with each. This communication will focus on the impact of CG in late life (over age 60) and will include a case vignette for illustrating complicated grief therapy.

Suicide bereavement and complicated grief

Losing a loved to suicide is one is one of life's most painful experiences. The feelings of loss, sadness, and loneliness experienced after any death of a loved one are often magnified in suicide survivors by feelings of quilt, confusion, rejection, shame, anger, and the effects of stigma and trauma. Furthermore, survivors of suicide loss are at higher risk of developing major depression, post-traumatic stress disorder, and suicidal behaviors, as well as a prolonged form of grief called complicated grief. Added to the burden is the substantial stigma, which can keep survivors away from much needed support and healing resources. Thus, survivors may require unique supportive measures and targeted treatment to cope with their loss. After a brief description of the epidemiology and circumstances of suicide, we review the current state of research on suicide bereavement, complicated grief in suicide survivors, and grief treatment for survivors of suicide.

Pharmacological approaches to the treatment of complicated grief: rationale and a brief review of the literature

Complicated grief (CG) is a common and often under-acknowledged cause of profound impairment experienced after the loss of a loved one. Although both clinical and basic research suggests that pharmacological agents might be of use in the treatment of CG, research on pharmacological approaches to this condition is still scarce. Three open-label trials and one randomized trial on bereavement-related depression suggest that tricyclic antidepressants may be effective, although they may be more efficacious for depressive symptoms than for grief-specific symptoms. Four open-label trials (total number of participants, 50) of selective serotonin reuptake inhibitors (SSRIs) have yielded results, providing very preliminary support that they might be effective in the treatment of CG, both as a standalone treatment and in conjunction with psychotherapeutic interventions. These more recent studies have shown an effect on both depression and grief-specific scales. Furthermore, therapeutic interventions for CG may be more effective in conjunction with SSRI administration. Given the small number of pharmacological studies to date, there is a need for randomized trials to test the potential efficacy of pharmacological agents in the treatment of CG.

Complicated grief therapy as a new treatment approach

Complicated grief therapy (CGT) is a relatively new psychotherapy model designed to address symptoms of complicated grief. Drawn from attachment theory and with roots in both interpersonal therapy (IPT) and cognitive-behavioral therapy, CGT includes techniques similar to prolonged exposure (repeatedly telling the story of the death and in vivo exposure activities). The treatment also involves focusing on personal goals and relationships. CGT has been demonstrated to be effective in a trial in which participants with complicated grief were randomly assigned to CGT or IPT; individuals receiving CGT responded more quickly and were more likely to respond overall (51% vs 28%). This article briefly summarizes the conceptual underpinnings of CGT, discusses the empirical evidence for its efficacy, describes its techniques, and presents a case example of a client treated in a 16-session manualized CGT protocol. The article concludes with a description of future research directions for CGT.

Suicide bereavement and complicated grief

Losing a loved to suicide is one is one of life's most painful experiences. The feelings of loss, sadness, and loneliness experienced after any death of a loved one are often magnified in suicide survivors by feelings of quilt, confusion, rejection, shame, anger, and the effects of stigma and trauma. Furthermore, survivors of suicide loss are at higher risk of developing major depression, post-traumatic stress disorder, and suicidal behaviors, as well as a prolonged form of grief called complicated grief. Added to the burden is the substantial stigma, which can keep survivors away from much needed support and healing resources. Thus, survivors may require unique supportive measures and targeted treatment to cope with their loss. After a brief description of the epidemiology and circumstances of suicide, we review the current state of research on suicide bereavement, complicated grief in suicide survivors, and grief treatment for survivors of suicide.

Recent trends in the treatment of prolonged grief

PURPOSE OF REVIEW

Treatment for prolonged grief has been controversial. However, recent studies have clarified several key issues, offering important guidance to clinicians. This review summarizes the most recent evidence on the efficacy of grief treatments, moderators of treatment response, and new treatment approaches.

RECENT FINDINGS

Recent research findings highlight that grief therapy is efficacious when targeted to adult and child grievers with persistent and elevated levels of distress. However, when grief therapy is applied as a universal intervention, it has minimal to no benefits, either for adults or for children. Earlier intervention for children is associated with greater efficacy. In recent studies, therapies employing cognitive-behavioral techniques, such as cognitive restructuring and exposure, have shown particularly robust effects in ameliorating grief symptoms. Other intervention approaches, including pharmacotherapy, internet-based, family-based, and preventive, have shown initial promise, but insufficient data exist to validate their efficacy to date.

SUMMARY

Prolonged grief, a pattern of persistent and elevated distress following a loss, is increasingly recognized as an independent form of psychopathology that is responsive to treatment. Therapies that employ cognitive-behavioral techniques are efficacious in ameliorating the symptoms of prolonged grief and should be more widely used. However, grief therapy should not be deployed as a blanket intervention for all grievers. Antidepressant medication may serve a useful adjunctive role in grief therapy completion and in reducing bereavement-related depression.

Complicated grief among individuals with major depression: prevalence, comorbidity, and associated features

BACKGROUND

Growing data suggest that complicated grief (CG) may be common in clinical care settings, but there are few prior reports about CG in outpatients presenting with primary mood disorders.

METHODS

The present study examined rates of bereavement and threshold CG symptoms (defined as a score ≥ 25 on the Inventory of Complicated Grief scale) in 111 outpatients with major depressive disorder (MDD) and 142 healthy controls participating in a study of stress and depression. Clinical and demographic characteristics were also compared for bereaved individuals with CG (MDD+CG) to those without (MDD-CG). Participants completed structured diagnostic interviews as well as measures of CG, depression, anxiety, exposure to traumatic events, and perceived social support.

RESULTS

Lifetime history of a significant loss did not differ for the MDD and control groups (79.3% vs. 76.1%), but bereaved participants with MDD had higher rates of threshold CG (25.0% vs. 2.8%). Among those with MDD, CG was associated with a higher prevalence of lifetime alcohol dependence, greater exposure to traumatic events, and lower perceived social support. Depressed women, but not men, with CG also had higher rates of panic disorder, social anxiety disorder, and posttraumatic stress disorder.

LIMITATIONS

Our findings are limited by the lack of a clinician confirmatory assessment of CG diagnosis, absence of complete information about the nature and timing of the loss, and relatively narrow generalizability.

CONCLUSIONS

We found high rates of CG in a group of psychiatric outpatients with chronic MDD, suggesting that patients with depression should be routinely screened for CG.

Complicated grief treatment: the theory, practice and outcomes

Many people resist the notion that grief could be considered a mental disorder, but the depth of some bereaved people's distress can mean they experience very great difficulty in progressing through the natural healing process. This article outlines an attachment theory perspective on the concept of complicated grief and a research-validated treatment (complicated grief therapy) that has been found to be effective in helping people address impediments that keep them from integrating the new reality of their lives.

Grief and bereavement: what psychiatrists need to know

THIS REVIEW COVERS FOUR AREAS OF CLINICAL IMPORTANCE TO PRACTICING PSYCHIATRISTS: a) symptoms and course of uncomplicated (normal) grief; b) differential diagnosis, clinical characteristics and treatment of complicated grief; c) differential diagnosis, clinical characteristics and treatment of grief-related major depression; and d) psychiatrists' reactions to patient suicides. Psychiatrists often are ill prepared to identify complicated grief and grief-related major depression, and may not always be trained to identify or provide the most appropriate course of treatment. Both conditions overlap with symptoms found in ordinary, uncomplicated grief, and often are written off as "normal" with the faulty assumption that time, strength of character and the natural support system will heal. While uncomplicated grief may be extremely painful, disruptive and consuming, it is usually tolerable and self-limited and does not require formal treatment. However, both complicated grief and grief-related major depression can be persistent and gravely disabling, can dramatically interfere with function and quality of life, and may even be life threatening in the absence of treatment; and both usually respond to targeted psychiatric interventions. In addition, patient suicide has been reported as one of the most frequent and stressful crises experienced by health providers, and psychiatrists are not immune to complicated grief or grief-related depression when they, themselves, become survivors. Thus, it is essential for psychiatrists to recognize their own vulnerabilities to the personal assaults that often accompany such losses, not only for their own mental health and well-being, but also to provide the most sensitive and enlightened care to their patients.

Duelo prolongado y factores asociados

Objetivo: Describir factores asociados a la presencia de Duelo Prolongado (DP) medido con el cuestionario Prolonged Grief Disorder-13 (PG-13) en pacientes que han perdido a un ser querido entre 6 y 18 meses.Método: Estudio transversal. Dolientes mayores de edad procedentes de atención primaria, hospitales de cuidados paliativos y un equipo de soporte a la atención domiciliaria paliativa en Madrid. Se recogieron variables del fallecido y del doliente: sociodemográficas, socioeconómicas, antecedentes psiquiátricos, utilización de recursos sanitarios, Trastorno por Ansiedad Generalizada (TAG), apoyo social, percibido y duelo prolongado con PG-13 y el Inventario Texas Revisado de Duelo (ITRD). Se calcularon medidas de tendencia central y distribución de frecuencias, se calculo asociación entre variables con c2 y t-student, se ajustó modelo multivariante.Resultados: La prevalencia de DP fue de 7,023%. La presencia de DP se asoció significativamente con ser mujer, no tener trabajo, ingresos familiares bajos, fallecido más joven, enfermedad no susceptible de recibir cuidados paliativos, historia de ansiedad y/o depresión antes y después de la pérdida, haber consultado a un psiquiatra, haber tomado psicofármacos, una mayor frecuentación de los servicios de urgencias, medicina y enfermería de atención primaria, con TAG, EDM, apoyo social percibido bajo y DP según los criterios del ITRD. En el análisis multivariante se asoció con haber visitado al psiquiatra, EDM y con ingresos mensuales inferiores a 2.000 euros.Conclusiones: Podemos modificar pocos de estos factores, pero conocerlos e identificar con prontitud a estos pacientes nos permitirá derivarlos a tratamientos apropiados como terapia específica de duelo.
