Predictors of treatment response for cognitive behaviour therapy for prolonged grief disorder

Linguistic predictors of symptom change in an internet-based cognitive behavioural intervention for prolonged grief symptoms

This study investigates linguistic predictors of reduction in prolonged grief symptoms following a writing intervention in an internet-based cognitive behavioural therapy for people bereaved by cancer. Data stem from a randomized control clinical trial with 70 people. The Linguistic Inquiry and Word Count program was used to analyse patient language. Absolute change scores and reliable change index were used to calculate reduction in grief symptoms and clinical significant change. Best subset regression and Mann-Whitney U tests were conducted. A higher reduction of prolonged grief symptoms was correlated with more social words in the first module (β = -.22, p = .042), less risk (β = .33, p = .002) and body words (β = .22, p = .048) in the second module and more time words in the third module (β = -.26, p = .018). Patients with clinically significant change showed a higher median in function words in the first module (p = .019), a lower median in risk words in the second module (p = .019) and a higher median in assent words in the last module (p = .014) compared to patients without clinically significant change. Findings suggest that it may be beneficial for therapists to encourage a more detailed description of patients' relationship with their deceased relative during the first module, a change in perspective during the second module and a summary of past, present and future aspects at the end of therapy. Future studies should include mediation analyses to allow causal attribution of the studied effects.

Factors Associated With Treatment Response in an Internet-Based Intervention for Prolonged Grief Disorder After Cancer Bereavement

Internet-based psychological interventions have proven effective in the treatment of prolonged grief disorder (PGD). Yet, some patients do not benefit from treatment in a clinically significant way. We aimed to examine predictors of symptom reduction in an Internet-based intervention for PGD after cancer bereavement, in order to identify possible treatment mechanisms and discern directions for future intervention design. A secondary analysis of data from a randomized wait-list controlled trial on an Internet-based intervention for PGD after cancer bereavement was conducted. Multiple regression models were used (1) to test for the influence of pretreatment PGD, working alliance, avoidance and gender on PGD symptom reduction; and (2) to explore further predictors of treatment success with a best subset selection protocol. The regression models explained 18% (Model 1) and 34% (Model 2) of variance in symptom reduction. Participants with more favorable symptom change had more severe pretreatment PGD scores and better working alliance. Those with lower social support and less posttraumatic growth experienced more PGD symptom change. In conclusion, therapeutic alliance is an important factor that should be monitored and fostered. Findings regarding social support and posttraumatic growth need further replication and clarification.

The relationship between culture-related grief beliefs, prolonged grief disorder and suicide ideation among Shidu parents in rural China

BACKGROUND

There are many one-child families in China due to the one-child policy. Parents who have lost their only child and are unable to conceive another child or unwilling to adopt a child are called Shidu parents in China. The death of an only child puts Shidu parents at the risk of mental illness and even suicide. Few studies have explored the influence of cultural beliefs and prolonged grief disorder on suicide ideation.

METHODS

This study involved rural Shidu parents from Sujiatun district of Shenyang, China. Questionnaires consisted of the Prolonged Grief questionnaire - 13 (PG-13), the Culture-related Grief Beliefs of Shidu Parents Questionnaire (CBSQ), one question from the baseline National Comorbidity Survey (NCS) to measure suicide ideation and demographic and bereavement-related information. Bivariate logistic regression analyses were conducted to explore associated factors of suicide ideation.

RESULTS

Sixty-nine (28.8%) of the 240 Shidu parents reported having suicide ideation. Having chronic disease (OR = 5.509, p < 0.01), having religious belief (OR = 3.923, p < 0.05) and having a grandchild (OR = 2.552, p < 0.05) were associated with an increased risk of suicide ideation. Destiny belief (a subscale of CBSQ) was negatively associated with suicide ideation (OR = 0.818, p < 0.05). Prolonged grief disorder (OR = 9.280, p < 0.01) and perceived stigma (a subscale of CBSQ) (OR = 1.200, p < 0.05) was positively associated with suicide ideation after adjusting for controlling variables.

CONCLUSIONS

Suicide ideation is prevalent in rural Shidu parents. Reducing perceived stigma and alleviating prolonged grief disorder may decrease the risk of suicide among rural Shidu parents.

Potential risk factors for acute grief during the COVID-19 pandemic: The mediating role of avoidance processes

Bereavement during the COVID-19 pandemic may have some unique characteristics that become potential risk factors (e.g., absence of grief rituals, no opportunity to say goodbye to the deceased and loneliness caused by social distancing) for acute grief. Avoidance processes could be significant mediators in the context of the pandemic. The current study aimed to investigate whether and how these COVID-19-related risk factors were related to acute grief severity. Bereaved adults (n = 319) who lost significant others during the COVID-19 pandemic completed a self-report questionnaire package measuring COVID-19-related factors, grief severity and depressive and anxious avoidance. Regression analyses suggested that among the three potential risk factors (loneliness, grief rituals and opportunity to say goodbye), loneliness was significantly associated with acute grief after controlling for basic demographic and loss-related information. Structural equation models suggested that depressive avoidance and anxious avoidance partially mediated the associations of loneliness with acute grief severity. The findings indicate that dealing with loss during the COVID-19 pandemic warrants further exploration concerning how potential environmental risk factors may impede adaptation to loss. Depressive and anxious avoidance processes may play important roles in grief interventions for isolated and lonely bereaved people.

Predictors of prolonged grief in an internet-based grief therapy for people bereaved by suicide

Internet-based cognitive-behavioural grief therapy (ICBGT) has proven to be effective for people bereaved by suicide, however the extent to which patients can benefit from therapy seems to differ. This study investigates predictors of initial grief as well as change in grief severity following treatment in an ICBGT for people bereaved by suicide. Data was gathered from a randomized control trial including 57 people participating in a 5-week intervention. Change in grief symptoms was calculated using absolute change scores of grief. In order to examine best overall combination of independent variables, best subset regressions were conducted. Higher levels of pre-test grief were associated with worse sleep quality (β = 0.32, p = .002), lower self-esteem (β = -0.37, p = .002), lower support seeking (β = -0.38, p = .006), and a higher need for social support (β = 0.28, p = .028). A greater reduction in grief severity was associated with higher self-efficacy (β = -0.49, p = .001), higher attachment anxiety (β = -0.31, p = .017) and higher pre-test grief symptoms (β = -0.39, p = .006). Attention should be paid to the intensity of grief, the attachment style and a positive self-image, as these variables seem to influence the extent, to which patients' symptoms of PGD subside following ICBGT. To specifically target factors of patients that require improvement, further studies are needed.

[Before the diagnosis was established … A retrospective analysis of bereavement care in Germany]

INTRODUCTION

In Germany, many health care providers work in bereavement care. An epidemiological study of this field of work has not yet been conducted.

METHODS

In the initial survey of this three-phase trend study the situation of grief-specific health care in Germany in 2009/2010 is examined, i. e., at the time before the introduction of the new ICD-11 diagnosis of Prolonged Grief Disorder. For this purpose, bereavement care providers at different organizational levels participated in an online survey.

RESULTS

410 questionnaires were included in the study. Data analysis was descriptive. The most frequent reason for using grief-specific support services was the loss of a partner. In more than half of all cases of bereavement, people experienced a loss that was preceded by an illness and suffering. More than half of those providing bereavement care do not follow a concept of intervention.

DISCUSSION

There is considerable need for further development in German bereavement care, in particular with regard to qualification and the degree of professionalization, designation of the respective interventions, diagnostics, and intervention.

CONCLUSION

This three-phase trend study enables health care providers to derive bereavement care service standards that aim to treat people according to their needs. Whether the diagnosis of Prolonged Grief Disorder has led to changes in bereavement care is currently analyzed in the second survey phase of the study.

Online cognitive-behavioural therapy for traumatically bereaved people: study protocol for a randomised waitlist-controlled trial

INTRODUCTION

The traumatic death of a loved one, such as death due to a traffic accident, can precipitate persistent complex bereavement disorder (PCBD) and comorbid post-traumatic stress disorder (PTSD) and depression. Waitlist-controlled trials have shown that grief-specific cognitive-behavioural therapy (CBT) is an effective treatment for such mental health problems. This is the first study that will examine the effectiveness of online CBT (vs waitlist controls) in a sample exclusively comprised of people bereaved by a traumatic death. Our primary hypothesis is that people allocated to the online CBT condition will show larger reductions in PCBD, PTSD and depression symptom levels at post-treatment than people allocated to a waitlist. We further expect that reductions in symptom levels during treatment are associated with reductions of negative cognitions and avoidance behaviours and the experience of fewer accident-related stressors. Moreover, the effect of the quality of the therapeutic alliance on treatment effects and drop-out rates will be explored.

METHODS AND ANALYSIS

A two-arm (online CBT vs waiting list) open-label parallel randomised controlled trial will be conducted. Participants will complete questionnaires at pretreatment and 12 and 20 weeks after study enrolment. Eligible for participation are Dutch adults who lost a loved one at least 1 year earlier due to a traffic accident and report clinically relevant levels of PCBD, PTSD and/or depression. Multilevel modelling will be used.

ETHICS AND DISSEMINATION

Ethics approval has been received by the Medical Ethics Review Board of the University Medical Center Groningen (METc UMCG: M20.252121). This study will provide new insights in the effectiveness of online CBT for traumatically bereaved people. If the treatment is demonstrated to be effective, it will be made publicly accessible. Findings will be disseminated among lay people (eg, through newsletters and media performances), our collaborators (eg, through presentations at support organisations), and clinicians and researchers (eg, through conference presentations and scientific journal articles).

Prolonged Grief Disorder Among Refugees in Psychological Treatment-Association With Self-Efficacy and Emotion Regulation

BACKGROUND

While Prolonged Grief Disorder (PGD) among refugees has recently started to attract scientific attention, knowledge regarding associated psychological factors remains limited. Given the multifactorial context of persecution, trauma, displacement, and exile-related difficulties, obtaining a better understanding of PGD in refugees is crucial because PGD may affect psychological well-being, level of functioning, and social integration.

METHODS

In a sample of refugees receiving psychological treatment in Switzerland (N = 88), we examined the relationship between severity of PGD and potentially associated factors such as emotion regulation, perceived self-efficacy, as well as potentially traumatic events and post-migration living difficulties.

RESULTS

In a regression analysis, difficulties in emotion regulation and lower perceived self-efficacy were associated with greater severity of PGD, while post-migration living difficulties and potentially traumatic events did not emerge as significant factors.

CONCLUSION

These findings suggest that emotion regulation and perceived self-efficacy are associated with PGD in refugees in psychological treatment and are thus potential targets for treatment interventions.

Predictive factors for differential changes in grief symptoms following group bereavement intervention for Chinese widowed older adults

This study aimed to delineate changes in the patterns of prolonged grief severity in widowed adults following group bereavement interventions and to identify the predictive factors impacting these patterns. We performed a secondary analysis of data from a randomized trial of 125 Chinese widowed older adults who participated in either LOGBI or DPGBI. Self-ratings of prolonged grief symptoms via Inventory of Complicated Grief (ICG) were subjected to latent class growth analysis to identify subgroups according to symptomatic changes among baseline, post-treatment, and 8-week follow-up. Multinomial regression analysis examined whether participant classification could be predicted by demographics, loss-related characteristics, and the relationship with the deceased and baseline symptom severity. In the results, intervention sample comprised 96 completers with an attendance greater than 60%. A three-class categorization yielded the best model fit for changes in prolonged grief severity for both randomized and intervention samples: improved class (41.6% in the randomized sample, 42.8% in the intervention sample), partial responded class (48.1%/45.5%), and relapse class (10.3%/11.8%). Older widowed adults experiencing a high level of grief at baseline and bereavement following chronic illness had an elevated risk of symptomatic relapse after the completion of intervention. These findings indicated that Chinese widowed adults experienced different changing patterns of prolonged grief severity following group bereavement interventions. Practically, widowed adults with a higher risk of symptomatic relapse might need more intensive or longer term intervention or follow-up support.

Traumatic loss: Mental health consequences and implications for treatment and prevention

Traumatic loss involves the loss of loved ones in the context of potentially traumatizing circumstances and is a commonly reported traumatic event. It may give rise to disturbed grief, called prolonged grief disorder (PGD) in ICD-11 and persistent complex bereavement disorder (PCBD) in DSM-5, combined with posttraumatic stress disorder (PTSD) and depression. The recent inclusion of grief disorders in both DSM-5 and ICD-11 have spurred research on grief-related psychopathology. This special issue on traumatic loss includes 10 articles and two letters. Topics addressed include diagnostic criteria for PGD, children's perspectives on life after parental intimate partner homicide, and the impact of visiting the site of deaths caused by terror. Early indicators of problematic grief trajectories are addressed, as well as moderators and mediators of disordered grief, including coping strategies, rumination, and meaning-making. Further, a meta-analysis synthesizing research findings on correlates of disturbed grief following traumatic loss is presented. Finally, specialized treatments as Eye Movement Desensitisation and Reprocessing (EMDR) and Cognitive Behavioural Therapy (CBT) for grief are addressed, and predictors of treatment response for CBT for PGD including levels of self-blame and avoidance are scrutinized. As such, the articles included in this special issue increase our understanding of the needs of people confronted with traumatic loss and bring promising findings with regard to diagnosis, prevention, and specialized treatment in children, young people and adults. This article also introduces a hypothetical staging, profiling, and stepped care model which may offer a template to integrate existing and emerging research findings on possible courses and correlates of grief, in order to inform treatment decisions.
