Sleep disturbances in bereavement: A systematic review

Examining worry and secondary stressors on grief severity using machine learning

BACKGROUND & OBJECTIVES

Worry and loss-related secondary stressors appear to be important correlates of problematic grief responses. However, the relative importance of these variables in the context of established correlates of grief responding, ranging from indicators of identity disruption and demographic characteristics of the bereaved to characteristics of the loss of quality of the relationship with the deceased, is unknown. Modeling the relative associations of these factors can be problematic, given the high degree of collinearity between these variables. This study used a machine learning approach to provide accurate estimations of the relative importance of these correlates for post-loss symptom severity.

METHODS AND RESULTS

A convenience sample of 428 bereaved people who had lost a parent, spouse, or child in the last 30 to 365 days completed an online survey. Random forest regression modeling examined the effects of worry and secondary stressors on symptom severity in the context of established correlates. Results indicated worry and the number of secondary stressors experienced were among the factors most strongly associated with severity of grief, depression, posttraumatic stress and problems functioning.

CONCLUSIONS

These results also provide insight into the relative importance of worry and secondary stressors affecting grief severity to guide future research.

ICD-11 and DSM-5-TR prolonged grief symptoms and quality of life: A criterion validity test

OBJECTIVE

Two similar but distinct versions of prolonged grief disorder (PGD) have recently been included in the International Classification of Diseases eleventh edition (ICD-11) and the Diagnostic and Statistical Manual of Mental Disorders - fifth edition, Text-Revision (DSM-5-TR). This study provides a criterion validity test of both new criteria sets of PGD, by examining concurrent and longitudinal associations of ICD-11 and DSM-5-TR prolonged grief symptoms with quality of life (QOL).

METHODS

Bereaved adults completed a survey assessing ICD-11 and DSM-5-TR prolonged grief symptoms, depressive symptoms, insomnia symptoms and QOL at baseline and 6-month follow-up.

RESULTS

Both ICD-11 and DSM-5-TR prolonged grief symptoms related negatively to QOL concurrently, while controlling for insomnia and depressive symptoms. ICD-11 prolonged grief symptoms, but not DSM-5-TR prolonged grief symptoms, predicted QOL at 6-month follow-up, while controlling for baseline QOL and insomnia and depression symptoms.

CONCLUSIONS

Results provide consistent evidence for the criterion validity of ICD-11 PGD, but mixed evidence for the criterion validity of DSM-5-TR PGD. Study results can help guide attempts to optimize and harmonize future PGD criteria.

Evaluating the Effect of Participation in Bereavement Support Groups on Perceived Mental Well-Being and Grief Reactions

The study aimed to evaluate the effect of participating in bereavement support groups on mental well-being and levels of grief and to gather information about participants´ experiences of participation. The programme consisted of six sessions over six weeks. Data were collected with the Warwick Edinburgh Mental Well-Being Scale (WEMWBS) and the Adult Attitude to Grief scale (AAG) as well as demographic and open-ended questions. 64 bereaved spouses returned at least parts of the study´s questionnaires before participating in the programme while 39 returned the complete WEMWBS and 36 the complete AAG both before and after participation. Most participants were women >60 years old. Participation in the programme resulted in a significant increase in perceived mental well-being and significantly lower levels of vulnerability in grief. Responses to open-ended questions revealed both positive and negative experiences. A lowered WEMWBS score and a relatively high AAG underscore the importance of providing services to the recently bereaved. Routine screening for complicated grief before participating in the bereavement support group sessions is recommended.

Support for Complicated Grief in Military Primary Care: Associations, Challenges, and Opportunities

OBJECTIVE

This study examined whether service members and their families engage in communication with their primary care managers (PCMs) regarding their losses and to what extent PCMs provide counseling or referrals for grief-related concerns. Additionally, the study explored the potential associations between ethnicity, age, military status (dependent, service member, or veteran), gender, patients' disclosure of loss to their PCM, receipt of referrals for grief-related services, and treatment seeking.

METHODS

A survey was administered to 161 patients enrolled in primary care at William Beaumont Army Medical Center, with 138 reporting a significant loss. Bereaved respondents completed the Inventory of Complicated Grief and the Prolonged Grief Disorder-13 Revised scale (PG-13). Respondents were also asked questions related to their loss and their interactions with their PCM related to the loss.

RESULTS

One hundred twenty-five bereaved respondents completed the measures, 13 had missing information related to PCM interactions. Twenty-nine percent (n = 36) of the 112 respondents reported a significant loss to their PCM. These respondents exhibited significantly higher symptom severity, as indicated by their total mean scores on the Inventory of Complicated Grief and the PG13. Seventeen percent (n = 6) of these respondents reported receiving counseling on topics related to grief or a referral for grief care from their PCM. A moderate relationship was identified between military status and communication with PCM, such that current service members were least likely to report, followed by veterans, then dependents. A moderate relationship was also found between ethnicity and treatment seeking.

CONCLUSION

The study's findings have implications for primary care and highlight opportunities for improved outcomes, including the development of appropriate assessment protocols, interventions, and educational initiatives to address grief-related concerns within the military healthcare system. Future research should further investigate the specific needs and preferences of military personnel and their families to enhance the delivery of targeted and effective healthcare services.

Predicting levels of prolonged grief disorder symptoms during the COVID-19 pandemic: An integrated approach of classical data exploration, predictive machine learning, and explainable AI

BACKGROUND

Prior studies on Prolonged Grief Disorder (PGD) primarily employed classical approaches to link bereaved individuals' characteristics with PGD symptom levels. This study utilized machine learning to identify key factors influencing PGD symptoms during the COVID-19 pandemic.

METHODS

We analyzed data from 479 participants through an online survey, employing classical data exploration, predictive machine learning, and SHapley Additive exPlanations (SHAP) to determine key factors influencing PGD symptoms measured with the Traumatic Grief Inventory - Self Report (TGI-SR) from 19 variables, comparing five predictive models.

RESULTS

The classical approach identified eight variables associated with a possible PGD (TGI-SR score ≥ 59): unexpected causes of death, living alone, seeking professional support, taking anxiety and/or depression medications, using more grief services (telephone or online supports) and more confrontation-oriented coping strategies, and higher levels of depression and anxiety. Using machine learning techniques, the CatBoost algorithm provided the best predictive model of the TGI-SR score (r2 = 0.6479). The three variables influencing the most the level of PGD symptoms were anxiety, and levels of avoidance and confrontation coping strategies used.

CONCLUSIONS

This pioneering approach within the field of grief research enabled us to leverage the extensive dataset collected during the pandemic, facilitating a deeper comprehension of the predominant factors influencing the grieving process for individuals who experienced loss during this period.

LIMITATIONS

This study acknowledges self-selection bias, limited sample diversity, and suggests further research is needed to fully understand the predictors of PGD symptoms.

Disruptions in self-regulatory processes predict depression and sleep disturbance in bereaved young adults

Losing a loved one is both common and profoundly stressful for young adults. Little research has examined the longitudinal course of post-loss cognitive processing, depression, and sleep difficulties. Further, little is known about the context of other stressors or the role of individual regulatory resources, such as attentional regulation, that might determine whether loss-related cognitive processing reduces distress. This prospective study examined changes in depression and sleep disturbance over 9 weeks as a function of within- and between-person variation in stress exposure, loss-related cognitive processing, and attention regulation. Participants were 108 recently bereaved college students completing a lab-based assessment of attention regulation and four self-report surveys, spaced three weeks apart. Results revealed that most participants gradually reduced loss-related processing over the study period, with corresponding improvements in depression and sleep. Stress exposure was associated with increased processing, depression, and sleep disturbance. In exploratory analyses, high attentional alertness and slow re-orienting strengthened the association of within-person loss processing with sleep disturbance. Both within- and between-person variation in stress appear to engender risk for a prolonged course of bereavement. Future research should integrate objective attention measures with self-reported adjustment to stress to illuminate reciprocal links between depression, sleep, and loss-related cognitive processing.

Prevalence and Correlates of Complicated Grief in Military Primary Care: Implications for Healthcare Providers

Grief is a universal experience, but for approximately 1 in 10 individuals, grief can become impairing. Despite servicemembers' frequent exposure to death, research on grief in the military remains limited. The purpose of the study was to explore the prevalence and correlates of complicated grief (CG) in military primary care. A quantitative survey was conducted with 161 non-treatment-seeking service members, veterans, and their dependents, of whom 138 reported a significant loss. Results revealed that 35% of the respondents who were bereaved met the cut-off score of 25 on the Inventory of Complicated Grief (ICG). Furthermore, 10% met the cut-off score of 30 on the Prolonged Grief Disorder-13-Revised Scale (PG-13-R). Importantly, death by suicide and pre-existing mental health conditions were associated with greater symptom severity. These findings have important implications for primary care providers and other clinicians working with military populations.

Trajectories of insomnia following bereavement

BACKGROUND

Insomnia symptoms are common following bereavement and may exacerbate severe and protracted grief reactions, such as prolonged grief disorder (PGD). However, typical trajectories of insomnia symptoms and risk factors for having a more chronic insomnia trajectory following bereavement are yet unknown.

METHOD

In the current investigation, 220 recently bereaved (≤6 months post-loss) participants, completed questionnaires assessing sociodemographic and loss-related characteristics, rumination, experiential avoidance and symptoms of (prolonged) grief and depression, on three time-points (6 months apart). We applied growth mixture models to investigate the typical trajectories of insomnia symptoms following bereavement.

RESULTS

Three insomnia trajectory classes emerged, characterized by a resilient (47 %), recovering (43 %), and a chronic trajectory (10 %). Baseline depression symptoms best predicted the type of insomnia trajectory. At one-year follow-up, 9 %, 27 %, and 60 % of participants met the criteria for probable PGD within the resilient, recovering and chronic trajectory, respectively. A parallel process model showed that temporal changes in insomnia symptoms were strongly related to changes in prolonged grief symptoms.

CONCLUSION

The results suggest, that targeting insomnia symptoms in the treatment of PGD, particularly with comorbid depression, may be a viable option.

Nightmare experiences and perceived ethnic discrimination amongst female university students in the United Arab Emirates: a cross-sectional study

Perceived ethnic discrimination is known to be associated with anxiety and depression, and in turn, anxiety and depression are known to be associated with nightmare frequency and distress. This elicits a question: is perceived ethnic discrimination associated with nightmare frequency and distress? In this study, 179 female university students from the United Arab Emirates were assessed to answer that question. Results showed that while anxiety and depression were related to nightmare experiences, perceived ethnic discrimination was a stronger predictor of nightmare experiences. We posit two explanations for this finding: one based on psychoanalytical insights, and the other based on the Disposition-Stress model with neurobiological correlates. No significant differences were found across ethnicity when it comes to nightmare experiences or perceived ethnic discrimination. This is an encouraging sign of optimal societal integration in the United Arab Emirates.

Somatic symptoms and insomnia among bereaved parents and siblings eight years after the Utøya terror attack

Background: Levels of prolonged grief symptoms (PGS) and post-traumatic stress symptoms (PTSS) can be high, many years following bereavement after terror, but knowledge concerning somatic health is scarce. Terrorism is a serious public health challenge, and increased knowledge about long-term somatic symptoms and insomnia is essential for establishing follow-up interventions after terrorism bereavement.Objective: To study the prevalence of somatic symptoms and insomnia and their association with PGS, PTSS, and functional impairment among terrorism-bereaved parents and siblings.Methods: A cross-sectional quantitative study included 122 bereaved individuals from the Utøya terror attack in Norway in 2011. The sample comprised 88 parents and 34 siblings aged 19 years and above (Mage = 49.7 years, SDage = 13.8 years, 59.8% females). The participants completed questionnaires 8 years after the attack assessing somatic symptoms (Children's Somatic Symptoms Inventory) and insomnia (Bergen Insomnia Scale) along with measures of PGS (Inventory of Complicated Grief), PTSS (Impact of Event Scale-Revised), and functional impairment (Work and Social Adjustment Scale).Results: Fatigue was the most frequently reported somatic symptom (88% of females and 65% of males). Females reported statistically significantly more somatic symptoms than males. In total, 68% of the bereaved individuals scored above the cut-off for insomnia. There were no statistically significant gender differences for insomnia. Female gender, intrusion, and arousal were associated with somatic symptoms. Intrusion and somatic symptoms were associated with insomnia. Somatic symptoms, avoidance, and hyperarousal were associated with functional impairment.Conclusion: Many bereaved parents and siblings report somatic symptoms and insomnia eight years after the terror attack. Somatic symptoms are associated with functional impairment. Long-term follow-up and support after traumatic bereavement should focus on somatic symptoms and insomnia.

Sleep quality moderates the association between family bereavement and heart rate variability

Two separate bodies of literature point to the link between family bereavement and cardiovascular health and between sleep quality and cardiovascular outcomes. However, less is known about the joint influence of family bereavement and sleep quality on cardiovascular functioning. The aims of this study were to examine the relationships between experiencing the death of a family member and heart rate variability (HRV) and to further explore whether these associations differ by sleep quality. Using data from the Midlife in the United States (MIDUS) Biomarker Project, the sample for this study included respondents who experienced the death of an immediate family member - father, mother, spouse, sibling, or child - within a year before the Biomarker project and those who did not experience any deaths (N = 962). We used two measures of HRV and sleep quality was measured using the Pittsburgh Sleep Quality Index. Results showed that experiencing the death of a family member was associated with worse HRV only among those with poor sleep quality and not for those with good sleep quality. These results suggest that poor sleep quality may indicate psychophysiological vulnerability for those who experienced the death of a family member. Interventions to improve sleep quality could be effective in enhancing cardiovascular health of bereaved individuals.

Prevalence of Prolonged Grief Disorder and Related Clinical Factors Among Turkish Psychiatric Outpatients During the COVID-19 Pandemic

Prolonged grief disorder (PGD), a new diagnosis in some classification systems, has gained prominence due to the high mortality rates observed during the Covid-19 pandemic. Herein, the prevalence of PGD (diagnosed with structured clinical interviews), death-related features, and associated clinical factors were investigated among outpatient psychiatric patients who lost a first-degree relative within the past 12-24 months. PGD was diagnosed in 30/68 patients (44.1%). PGD development did not differ based on cause of death (Covid-19-related vs. other causes) but was associated with higher age of the bereaved, younger age of the deceased, and degree of kinship. Higher rates of depression, insomnia, and anxious attachment were also observed in PGD patients. Finally, the unexpectedness of death predicted the development of PGD. Due to the high prevalence of PGD among psychiatric patients, clinicians should be aware of the disorder, monitor grief processes in high-risk patients, and consider PGD in treatment planning.

Manuscript: effects of bereavement on graduate students: a qualitative study

Abstract Introduction Bereavement can be characterized by the loss, through death, of a significant person. Individuals who experience bereavement can experience changes in their roles, habits, and routines. In addition, individuals can experience changes in their occupations, such as social and leisure participation and in their activities of daily living. Objective This research aimed to identify graduate students' needs and problem areas following the loss of a loved one to better inform the role of occupational therapy in assisting students during the bereavement process. Method This study utilized a mixed-methods approach. The survey developed and distributed to participants contained qualitative and quantitative data to understand better the relationship between grief, occupational participation, and academic performance. Results This study reviewed the students' needs and problem areas after losing a loved one and determined the areas that impact students' daily living. Conclusion This study demonstrated that losing a loved one affects students' academic performance and ability to perform daily activities.

Insomnia and Other Sleep Disorders in Older Adults

Sleep disruption is common in older adults and is associated with many poor health outcomes. It is vital for providers to understand insomnia and other sleep disorders in this population. This article outlines age-related changes in sleep, and medical, psychiatric, environmental, and psychosocial factors that may impact sleep. It addresses the evaluation of sleep symptoms and diagnosis of sleep disorders. It aims to examine the evidence for non-pharmacological and pharmacologic treatment options for insomnia while weighing factors particularly germane to the aging adult..

Cross-Lagged Analyses of Prolonged Grief and Depression Symptoms with Insomnia Symptoms

Prolonged grief disorder, characterized by severe, persistent and disabling grief, has recently been added to the DSM-5-TR and ICD-11. Treatment for prolonged grief symptoms shows limited effectiveness. It has been suggested that prolonged grief symptoms exacerbate insomnia symptoms, whereas insomnia symptoms, in turn, may fuel prolonged grief symptoms. To help clarify if treating sleep disturbances may be a viable treatment option for prolonged grief disorder, we examined the proposed reciprocal relationship between symptoms of prolonged grief and insomnia. On three time points across 6-month intervals, 343 bereaved adults (88% female) completed questionnaires to assess prolonged grief, depression, and insomnia symptoms. We applied random intercept cross-lagged panel models (RICLPMs) to assess reciprocal within-person effects between prolonged grief and insomnia symptoms and, as a secondary aim, between depression and insomnia symptoms. Changes in insomnia symptoms predicted changes in prolonged grief symptoms but not vice versa. Additionally, changes in depression and insomnia symptoms showed a reciprocal relationship. Our results suggest that targeting insomnia symptoms after bereavement is a viable option for improving current treatments for prolonged grief disorder.

Stressful life events and subjectively rated sleep quality among older adults in China: the roles of positive and negative attitudes towards ageing

Sleep is an integral part of individuals' health and wellbeing. Despite evidence showing that social stressors are important contributors to older adults' sleep problems, how the accumulative stressful life events (SLEs) and ageing attitudes independently and jointly affect sleep quality among older adults in developing countries remains unclear. This study examined the effects of SLEs on subjectively rated sleep quality among older adults in China, and explored the potential mediating and moderating roles of positive and negative ageing attitudes on the above association. Using data from the 2014 China Longitudinal Ageing Social Survey, we had complete data for 7,780 older adults aged 60 and older. We employed logistic regression models and the Karlson–Holm–Breen decomposition method. Our findings indicated that SLEs significantly increased the risk of poor sleep quality, especially for those who had experienced two or more SLEs during the past year. Positive ageing attitudes were associated with lower odds of poor sleep quality, whereas negative ageing attitudes were related to higher odds of poor sleep quality. Moreover, the mediation analyses suggested that SLEs were associated with poor sleep quality via negative ageing attitudes. The moderating effects further documented that higher levels of positive ageing attitudes can significantly attenuate the deleterious impact of SLEs on sleep quality. The findings highlight the significance of SLEs for older adults' sleep quality and shed light on the importance of ageing attitudes to improve older adults' sleep in China as well as other low- and middle-income countries, where the social safety nets are still underdeveloped.

Determinants of natural adult sleep: An umbrella review

BACKGROUND

Sleep has a major impact on health, which makes it a relevant topic for research and health practitioners. Research on sleep determinants, i.e. factors that positively or negatively influence sleep, is fragmented.

OBJECTIVE

The purpose of this umbrella review is to provide an overview of the current evidence on determinants of natural adult sleep.

METHODS

A comprehensive literature search was performed on determinants of sleep. Reviews and meta-analyses on natural adult sleep were included. Six electronic databases (PubMed, WoS, Embase, CINAHL, PsycInfo and Cochrane) were used for the search, last accessed September 2021. The quality of the selected articles was assessed using the AMSTAR2 tool. Results were categorized in four main categories: biological, behavioral, environmental and personal/socio-economical determinants.

RESULTS

In total 93 reviews and meta-analyses resulted in a total of 30 identified determinants. The impact of each determinant differs per individual and per situation. Each determinant was found to affect different sleep parameters and the relationship with sleep is influenced by both generic and specific moderators.

DISCUSSION

A comprehensive overview on relevant sleep determinants provides a practical and scientifically based starting point to identify relevant intervention approaches to secure or improve individual sleep quality. The difference in aggregation level of the determinants and in measurement methods are the major limitations of this umbrella review. Extending existing generic sleep hygiene rules with an overview of all types of potential determinants will enhance the awareness of the complexity and can be used to improve the effect of sleep interventions in health promotion.

Self-Reported Sleep during the COVID Lockdown in a Sample of UK University Students and Staff

The link between disturbed sleep and the extended lockdown period resulting from COVID-19 is well established. Data from an online survey of 2341 of university students (n = 1972, 84.2%) and staff were reported. Overall (n = 1710, 73.1%) were female and the mean age for the sample was 29.26 (SD = 12.86). 1799 (76.8%) provided self-reported data from the Nottingham Health Profile (NHP) Sleep Subscale that allowed sleep to be compared prior to the lockdown period and during the lockdown period. Sociodemographic data which included, gender, age, whether an individual was a student or member of the university staff, ethnicity, caring responsibilities, and highest educational level were collected. Other data included, the NHP Sleep Sub-scale, change in alcohol consumption during the lockdown period, routine behaviours during the lockdown period, self-efficacy and health and wellbeing. There was a significant deterioration in NHP Sleep scores (p < 0.001) and all areas of sleep that were assessed significantly deteriorated during the lockdown period. These included indicators of sleep quality, sleep latency, sleep duration, sleep disturbance and increased use of sleep medication. Following a multinomial logit regression with change of NHP sleep scores entered as the dependent variable there were several significant predictors. Women had greater sleep dysfunction than men. Increased alcohol consumption, lower educational status and a deterioration in health and well-being scores were associated with greater sleep dysfunction. Not having a designated area to work in and not putting on clothes and make-up were both associated with greater sleep dysfunction during the lockdown period. These findings confirm the importance of taking steps to maintain sleep hygiene during extended lockdown periods.

An Internet-delivered Cognitive-Behavioral Therapy (iCBT) for Prolonged Grief Disorder (PGD) in adults: A multiple-baseline single-case experimental design study

The death of a loved one has physical, psychological, and social consequences. Between 9.8 and 21.5 % of people who lose a loved one develop Prolonged Grief Disorder (PGD). Internet- and computer-based interventions (i.e., Internet-delivered Cognitive-Behavioral Therapy, iCBT) are cost-effective and scalable alternatives that make it possible to reach more people with PGD. The main goal of the present investigation was to examine the effect and feasibility (usability and satisfaction) of an iCBT (GROw program) for adults with PGD. A secondary objective was to detect adherence to the app (Emotional Monitor) used to measure daily grief symptoms. The study had a single-case multiple-baseline AB design with six participants. The GROw program is organized sequentially in eight modules, and it is based on the dual-process model of coping with bereavement. Evaluations included a pre-to-post treatment assessment of depression, grief symptoms, and typical grief beliefs, along with daily measures of symptom frequency and intensity on the Emotional Monitor App. Treatment opinions and adherence to the App were also collected. Efficacy data were calculated using a Nonoverlap of All Pairs (NAP) analysis and Reliable Change Index (RCI). The mean age of the sample was 29.5 years (SD = 8.19). Two participants dropped out of the study. Adherence to the App varied across patients (4.8 % -77.8 %). Most participants (75 %) showed a clinically significant change (recovered) in depression, and 50 % obtained a clinically significant improvement (recovered) in symptoms of loss and typical beliefs in complicated grief. The participants reported high usability and satisfaction with the treatment content and format. In sum, the GROw program was very well accepted and generally feasible, and it has strong potential for treating PGD. The results support scaling up the treatment by using more complex designs with larger samples (i.e., randomized controlled trials comparing GROw with active conditions).

"It Started After Trauma": The Effects of Traumatic Grief on Sleep Paralysis

Adverse life events are associated with the often-terrifying REM sleep parasomnia of sleep paralysis (SP), but the impact of bereavement on SP has not been specifically examined. This exploratory, mixed-methods study (N = 168) includes qualitative data from 55 participants who described factors they believed led to their SP. Of these, almost half with a traumatic loss listed death-related precipitants. In unadjusted (bivariate) negative binomial regression models, traumatic death, time since death, religiosity, and age estimated increased SP frequency in the prior month, prior year, or both. In multivariable models, traumatic death, time since death, and age estimated increased frequency in the prior month, prior year, or both. Unexpectedly, in all models, as compared to death ≥9 years earlier, prior month SP was greater with death 1-6 years earlier, but not <1 year earlier. Discussion includes the possible role of social constraints in traumatic grief trajectories and care provider recommendations.

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.

[How grief moved from culture to psychiatry]

Bereavement has been debated among psychiatric experts since 2000. In addition to its precise manifestations, its duration is discussed: six months for the ICD-1, one year for the DSM-5-TR. Grief is not an illness but a process that can be blocked in the announcement phase of the death or in the depression phase following the absence. In all cases, acceptance of the loss is impossible. Psychiatric treatment can define a bereaved person who is suffering too much, and can reduce his or her suffering, but it cannot accelerate the process of remembering and then resuming a life without the loved one. Social rituals and psychosocial support have had this place for millennia in cultures throughout humanity.

Network analysis of PGD, PTSD and insomnia symptoms in Chinese shidu parents with PGD

Background

Chinese shidu parents (bereaved parents over the age of 49 who have lost their only child) are potentially at a high risk of prolonged grief disorder (PGD), posttraumatic stress disorder (PTSD) and insomnia.

Objective

The current study aimed to estimate three network models in 310 shidu parents who met the ICD-11 criteria for PGD: (1) a PGD network to identify central symptoms; (2) a comorbidity network to explore bridge symptoms between PGD and PTSD; (3) a comorbidity network to examine the associations between PGD and insomnia symptoms.

Methods

The R-packages bootnet, qgraph and networktools were used to investigate the structure of network models and centrality indices of symptoms. In addition, robustness and significance analyses for the edge weights and the order of centrality were performed.

Results

Emotional pain and numbness emerged as the most central symptoms in the PGD network. In the PGD-PTSD comorbidity network, the highest bridge strength symptoms were inability to trust others (PGD) and feeling upset (PTSD). Inability to trust others (PGD), avoidance (PGD), and impairment of life quality (insomnia) were possible bridge symptoms connecting PGD and insomnia.

Conclusions

Reducing emotional pain and numbness may be a viable target in PGD interventions for shidu parents. Additionally, findings suggest that future studies could examine the role of inability to trust others and avoidance in PGD comorbidities.

HIGHLIGHTS

• Emotional pain and numbness were the most influential symptoms in shidu parents with PGD. The role of PGD symptoms of inability to trust others and avoidance in the comorbidities of PGD with PTSD and insomnia might be worthy of further study.

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.

Losing a child due to a life-limiting diagnosis-parental well-being and quality of life: nationwide survey

OBJECTIVE

Losing a child is burdensome with potential long-term impact on the parents' well-being and quality of life. The aim was to investigate parental well-being and quality of life 3-5 years after losing a child due to life-limiting diagnoses and to identify associated factors in order to target future interventions.

METHODS

All parents, who lost a child (<18 years) due to life-limiting diagnoses in the period 2012-2014 in Denmark, were invited to complete a self-administered questionnaire. A seven-point Visual Digital Scale (VDS) was used to assess issues of well-being and quality of life including physical health, anxiety, depression and sleep quality which were combined into a cumulative symptom index. Associations were assessed by means of ordinal logistic regression models.

RESULTS

In all, 152 (38%) children were represented by 136 mothers and 57 fathers. Totally, 17.6% of the mothers and 14.0% of the fathers had ≥2 symptoms (assessed by the symptom index). Parents with lower education had 2.11 (95% CI: 1.01 to 4.40) times higher odds of having more symptoms than parents with higher education. Unmarried parents had 2.14 (95% CI: 1.03 to 4.42) times higher odds of having more symptoms than married parents. Ten per cent of the parents reported poor overall quality of life.

CONCLUSION

According to the VDS, 1 out of 10 parents experienced poor overall quality of life 3-5 years after the loss. Every sixth had two or more symptoms assessed by the symptom index. Associated factors for poor quality of life suggest attention to particularly unmarried parents and parents with lower education.

Internet-delivered Cognitive-Behavioral Therapy (iCBT) for Adults with Prolonged Grief Disorder (PGD): A Study Protocol for a Randomized Feasibility Trial

INTRODUCTION

Grief is an emotional reaction to the loss of a loved one with a natural recovery. Approximately 10% of people who lose a loved one develop prolonged grief disorder (PGD). Internet-based and computer-based interventions (ie, internet-delivered cognitive-behavioural therapy, iCBT) are a cost-effective alternative that makes it possible to reach more people with PGD. The main aim of this study is to assess the feasibility of a new iCBT-called GROw-for PGD. As a secondary objective, the potential effectiveness of GROw will be explored.

METHODS AND ANALYSIS

This study is a two-arm feasibility randomised trial. A total of 48 adults with PGD who meet the eligibility criteria will be randomised to the experimental group (iCBT: GROw) or the active control group (face-to-face CBT treatment). The treatment is organised sequentially in eight modules in the iCBT format and 8-10 sessions in the face-to-face format, and both formats have the same therapeutic components. There will be five assessment points with qualitative and quantitative evaluations: screening, baseline, after the intervention, 3-month follow-up and 12-month follow-up. Consistent with the objectives, the measures are related to the feasibility outcomes for the main aim of the study (participant adherence, expectations and satisfaction with the treatment, preferences, alliance and utility) and psychological and mental health outcomes for secondary analyses (symptoms of grief, symptoms of depression, symptoms of anxiety, affectivity, quality of life, work and social adaptation, post-traumatic growth, purpose in life, mindfulness and compassion).

ETHICS AND DISSEMINATION

The Ethics Committee of the Universitat Jaume I (Castellón, Spain) granted approval for the study (CD/002/2019). Dissemination will include publications and presentations at national and international conferences.

Rumination, worry and negative and positive affect in prolonged grief: A daily diary study

After bereavement, a significant minority experiences severe, persistent, and disabling grief, termed prolonged grief or complicated grief. Prolonged grief treatments may be enhanced by improving understanding of malleable risk factors in post‐loss psychological adaptation. Repetitive negative thought (e.g., rumination, worry) constitutes such a risk factor. Rumination and worry are both theorized to be maladaptive through interrelations with affect, yet this assumption has not been systematically investigated in the bereaved. We aimed to fill this gap in knowledge with a baseline survey and 10‐day daily diary investigation among a bereaved sample. Survey between‐subject analyses (N = 113) demonstrated that trait rumination and worry, trait negative affect and prolonged grief symptoms are positively related to each other and negatively related with trait positive affect. Within‐subject multilevel analyses of diaries (N = 62) demonstrated that trait rumination and trait worry relate positively to daily negative affect and negatively to daily positive affect. Daily rumination and worry showed similar relationships with daily negative and positive affect. A stronger relationship emerged between daily rumination and daily negative affect in people with higher prolonged grief symptom levels. Findings consistently support interrelations between repetitive negative thought, affect, and prolonged grief symptoms. Rumination appears particularly detrimental in people with severe grief reactions. Results align with research demonstrating the effectiveness of targeting repetitive negative thought in prolonged grief treatments. Additionally, our study demonstrates the potential feasibility and usefulness of using daily diaries to study behaviours of relevance to post‐loss adaptation in everyday life.

Feasibility and preliminary efficacy of guided internet-delivered cognitive behavioral therapy for insomnia after the loss of a child to cancer: Randomized controlled trial

Bereaved individuals often experience sleep problems. The aim of this study was to evaluate feasibility and preliminary effects of internet-delivered cognitive behavioral therapy for insomnia (iCBT-i) in bereaved parents. Parents were randomized to iCBT-i (n = 10) or an active control group (n = 11). Primary outcome (insomnia) and secondary outcomes (prolonged grief, depression, posttraumatic stress, and grief rumination) were assessed pre- and post-treatment, with 9- and 18-month follow-ups. Feasibility was assessed post-treatment and one month later. Most parents reported positive effects of the treatment. The intervention group improved significantly from pre- to post-treatment and had a significantly larger reduction of insomnia when analyzed over all four time-points (Wald χ² = 30.0, p < 0.001), although the effect at post-treatment was very small (d = 0.1) for insomnia. Thus, iCBT-i was feasible and was related to reduced insomnia and psychological distress in bereaved parents, both short- and long-term, but the results regarding the treatment effect are preliminary due to the small sample size.

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.

Sleep Disturbance, Sleep Disorders and Co-Morbidities in the Care of the Older Person

Sleep complaints can be both common and complex in the older patient. Their consideration is an important aspect of holistic care, and may have an impact on quality of life, mortality, falls and disease risk. Sleep assessment should form part of the comprehensive geriatric assessment. If sleep disturbance is brought to light, consideration of sleep disorders, co-morbidity and medication management should form part of a multifaceted approach. Appreciation of the bi-directional relationship and complex interplay between co-morbidity and sleep in older patients is an important element of patient care. This article provides a brief overview of sleep disturbance and sleep disorders in older patients, in addition to their association with specific co-morbidities including depression, heart failure, respiratory disorders, gastro-oesophageal reflux disease, nocturia, pain, Parkinson's disease, dementia, polypharmacy and falls. A potential systematic multidomain approach to assessment and management is outlined, with an emphasis on non-pharmacological treatment where possible.

The longitudinal association of actigraphy-estimated sleep with grief in middle-aged and elderly persons

Most people experience grief after a loss, about 10% develop complicated grief, often accompanied by sleep complaints. Yet, the role of objectively estimated poor sleep remains unclear. Therefore, we assessed the cross-sectional and longitudinal association of actigraphy-estimated sleep with grief. We included 1,776 participants (mean age: 61.8 ± 8.9 years, 55% women) of a prospective population-based cohort. Of 1,471 participants (83%) repeated measures of grief were available (median follow-up 6 years, inter quartile range 5.6-6.3). At baseline, sleep was objectively estimated using actigraphy (mean duration 6.0 ± 0.8days). At baseline and follow-up, participants were asked about significant losses and completed the Dutch Inventory of Complicated Grief (17 items, cut-off ≥22). At baseline 1,521 (86%) participants experienced no grief, 44 (2%) acute grief (<6 months, any grief score), 158 (9%) non-complicated grief (≥6 months, grief score<22), and 53 (3%) complicated grief (≥6 months, grief score≥22). In those indicating any grief (n = 255), low sleep efficiency (B = -0.16, 95%CI = -0.30;-0.02), long sleep onset latency (B = 0.07, 95%CI = 0.01; 0.14), and long wake after sleep onset (B = 0.06, 95%CI = 0.01; 0.10) were cross-sectionally associated with more grief symptoms. Over time, those with a short total sleep time (OR = 0.59, 95%CI = 0.39; 0.91), low sleep efficiency (OR = 0.95, 95%CI = 0.91; 0.99), long sleep onset latency (OR = 1.02, 95%CI = 1.00; 1.04), and long wake after sleep onset (OR = 1.02, 95%CI = 1.00; 1.03) at baseline more often experienced complicated grief than non-complicated grief at follow-up. This study suggests that objectively estimated poor sleep is associated with grief over time. Poor sleep might not only accompany grief, but also be a risk factor for developing complicated grief after a loss.

Predictive factors of insomnia during the COVID-19 pandemic in Bangladesh: a GIS-based nationwide distribution

Background

In a densely populated country like Bangladesh, mental health-related burden and associated adverse outcomes are quite prevalent. However, exploration of sleep-related issues in general, and more specifically of insomnia during the COVID-19 pandemic has been scarce and restricted to a single location. The present study investigated the prevalence of insomnia and its predictive factors in the general population, and included Geographic Information System (GIS) analysis to identify regional heterogeneities of insomnia in Bangladesh.

Methods

This cross-sectional study was conducted during the early period of the COVID-19 pandemic. Information related to socio-demographics, knowledge of COVID-19, behaviors related to COVID-19, fear of COVID-19, and insomnia were included in a questionnaire, and coupled with GIS-based spatial analysis to identify regional susceptibility to insomnia.

Results

Approximately 30.4%, 13.1% and 2.8% of participants reported sub-threshold, moderate, and severe forms of insomnia, respectively. Independent predictive risk factors of insomnia symptoms included female gender, college education, urban residence, presence of comorbidities, using social media, taking naps during daytime, and fear of COVID-19. District-wide variations in the spatial distribution of fear of COVID-19 and insomnia were significantly associated.

Conclusion

Insomnia is frequently present during a pandemic, and exhibits regional variability along with multifactorial determinants. These analytic approaches should enable improved detection and targeting of at-risk sectors of the population, and enable implementation of appropriate measures to ensure improved sleep quality.

Insomnia disorder and its reciprocal relation with psychopathology

Sleep is crucial for daytime functioning. In populations with psychiatric conditions, many people suffer from insomnia symptoms or an insomnia disorder. Emerging evidence suggests a bidirectional relationship between insomnia and various psychopathologies, implying that insomnia not only may be a consequence of mental disorders but also may contribute to new development, symptom severity, and reoccurrence of diverse mental disorders. Research on potential mechanisms underlying the insomnia psychopathology association is important, both from the preventive and treatment perspective. Most hypotheses concern the influence of insomnia on emotion regulation and on shared pathophysiological pathways, ranging from gut microbiome composition to genetic and specific neurotransmitter system aberrations.
