Do prolonged grief disorder symptoms predict post-traumatic stress disorder symptoms following bereavement? A cross-lagged analysis

Patterns and relationships of prolonged grief, post-traumatic stress, and depressive symptoms in Chinese shidu parents: Latent profile and network analyses

Parents who experience the trauma of losing an only child are called "shidu" parents in China. There are individual differences in post-loss outcomes.1,061 Chinese shidu parents were asked to complete questionnaires assessing prolonged grief, post-traumatic stress, and depressive symptoms. The mean age of the sample was 59.68 (SD = 7.52), with the average time since the loss was 9.46 years (SD = 7.05). Most participants were female (62.3%). The main cause of the loss was an unnatural case (52.7%). Latent profile analysis was used to identify similar symptom patterns. Network analysis was used to explore the relationships among symptoms within different subgroups. A two-profile model based on symptom severity identified a "low symptom severity" subgroup (n = 419) and a "high symptom severity" subgroup (n = 642). In the low symptom severity subgroup network, the most central symptoms were loss of interest, feeling numb, and meaninglessness. In the high symptom severity subgroup network, the most central symptoms were physiological cue reactivity, emotional pain, and feeling easily startled. Individual differences in the post-loss outcomes of Chinese shidu parents are reflected not only in symptom patterns but also in the relationships among symptoms.

A comprehensive investigation of comorbidities of prolonged grief disorder in a bereaved inpatient psychiatric sample

Prolonged Grief Disorder (PGD) was recently added to ICD-11 and DSM-5-TR. Depression and Posttraumatic Stress Disorder (PTSD) are frequent comorbidities, but findings regarding comorbid somatoform disorder and personality disorders remain mixed and studies with severely impaired patients are scarce. It was therefore the objective of the present study to examine comorbidities of PGD in a bereaved inpatient psychiatric sample. We assessed N = 101 bereaved inpatients in a psychiatric hospital with clinical interviews and self-report questionnaires. We calculated differences between patients with and without a PGD-diagnosis in number and type of comorbid disorders as well as associations between the severity of PGD and comorbid disorders. On average, patients had 2.53 comorbid psychiatric diagnoses. Patients with and without a PGD-diagnosis did not differ in their number of comorbid diagnoses, and there was no association between number of comorbid diagnoses and PGD-severity. However, patients with PGD, had significantly more comorbid diagnoses belonging to neurotic-, stress-related and somatoform disorders of the ICD-10. Patients with PGDICD-11 also had significantly higher scores in self-reported depressive, PTSD-, and somatoform symptoms, as well as the negative affectivity personality domain than those without a PGD diagnosis. To the best of our knowledge, this is the first study to provide insights into comorbidities of PGD in a bereaved inpatient psychiatric sample. It highlights the importance of considering PGD symptoms as part of the complaints of bereaved patients to achieve a tailored treatment approach. Future longitudinal studies are needed to unveil relationships between pre-existing mental disorders and PGD.

Traumatic loss: a systematic review of potential risk factors differentiating between posttraumatic stress disorder and prolonged grief disorder

Background: When traumatic events and losses intersect in the form of traumatic loss, these events can trigger both posttraumatic stress disorder and pathological grief.Objective: This systematic review investigates which characteristics differentiate between the development of the respective disorders or are associated with comorbidity.Method: A systematic literature search using Medline, PubMed, APA PsycInfo and Web of Science yielded 46 studies which met the inclusion criteria. In these studies, PTSD was assessed using 17 and pathological grief using 16 different validated instruments. In the quality assessment, 12 studies were classified as average, 30 as above average, and 4 as excellent. The investigated risk factors were categorized into 19 superordinate clusters and processed using narrative synthesis.Results: The relationship to the deceased, mental health issues, and religious beliefs seem to be associated specifically with pathological grief symptoms compared to PTSD symptoms. Social support and social emotions emerged as significant correlates and potential risk factors for both PTSD and pathological grief. Included studies had mainly cross-sectional designs.Conclusions: Differentiating factors between pathological grief and PTSD appear to exist. The results should be considered within the limitations of the heterogeneity of the included studies and the research field. There is a lack of studies (1) using a longitudinal study design, (2) starting data collection early following the traumatic loss, (3) using standardized, up-to-date measurement instruments and (4) including comorbidity in their analyses. Further research is urgently needed for more accurate (acute) screenings, prognoses, and interventions following traumatic loss.

Bidirectional associations between prolonged grief symptoms and depressive, anxiety, and posttraumatic stress symptoms: A systematic review

Prolonged grief symptoms frequently co-occur with symptoms of depression, posttraumatic stress, and anxiety; however, little is known about how prolonged grief symptoms temporally relate to symptoms of neighboring stress-related and affective disorders. Clarifying such associations can help elucidate which symptoms to prioritize during treatment for distressed bereaved adults. We conducted a systematic review to provide a comprehensive overview of the empirical research on the bidirectional temporal associations between prolonged grief symptoms and symptoms of depression, posttraumatic stress, and anxiety. A search of the PsycInfo, Web of Science, and Scopus databases (final search: December 2023) identified eight relevant empirical longitudinal studies utilizing lower-level mediation (two studies), cross-lagged panel modeling (CLPM; four studies), or random-intercept CLPM (RI-CLPM; two studies). The studies included a total of 2,914 bereaved adult participants. Studies showed considerable methodological heterogeneity, including different sample characteristics, study designs (e.g., measurement moments, time frames), statistical analyses, and measures. Temporal associations between prolonged grief symptoms and different types of symptoms appeared intertwined. Prolonged grief symptoms more consistently predicted symptoms of depression and posttraumatic stress across measurement waves than vice versa, tentatively suggesting that prolonged grief may be a transdiagnostic risk factor for depressive and PTS symptoms. However, this pattern was not observed in the two studies utilizing RI-CLPM. Future research should aim to decrease methodological heterogeneity by using validated measures to capture prolonged grief symptoms, appropriate timeframes, and RI-CLPM to clarify associations between temporal within-person fluctuations of prolonged grief, depressive, posttraumatic stress, and anxiety symptoms.

Prevalence, comorbidities, and factors associated with prolonged grief disorder, posttraumatic stress disorder and complex posttraumatic stress disorder in refugees: a systematic review

BACKGROUND

The number of refugees worldwide is at an all-time high with many being exposed to potentially traumatic events and the loss of loved ones. The 11th revision of the International Statistical Classification of Diseases and Related Health Problems now includes prolonged grief disorder and complex posttraumatic stress disorder and revised criteria for posttraumatic stress disorder. An overview of these stress-related disorders among people who have become refugees is therefore needed. Consequently, we conducted a systematic review to determine prevalence rates, comorbidities, and associated factors for each of the disorders.

METHOD

We systematically searched PubMed, Web of Science, and PsycArticles to identify studies that reported prevalence rates, predictors or associated factors, and/or comorbid mental disorders for either (1) prolonged grief disorder, (2) posttraumatic stress disorder, or (3) complex posttraumatic stress disorder among refugees. The selection process followed the PRISMA guidelines.

RESULTS

A total of 36 studies met the inclusion criteria. Most of the studies were of high quality. There was substantial variation in prevalence rates by disorder, with prolonged grief ranging from 6 to 54%, posttraumatic stress disorder ranging from 0.4 to 80%, and complex posttraumatic stress disorder ranging from 3 to 74.6%. Pooled prevalence for posttraumatic stress disorder was estimated at 29.8% in treatment seeking samples and 9.92% in population samples. For complex posttraumatic stress disorder, it was estimated at 57.4% in treatment seeking samples and 7.8% in population samples. Posttraumatic stress disorder was among the most frequent comorbidities for prolonged grief disorder while depressive symptoms were the most frequently occurring co-morbidity across all three disorders. Sociodemographic variables, trauma exposure, and loss characteristics were associated with higher symptom severity. Postmigration living difficulties played an important role in prolonged grief and complex posttraumatic stress disorder.

CONCLUSION

The review revealed substantial differences in prevalence rates between the three studied disorders but underscored a very high prevalence of ICD-11 stress-related disorders among refugees. The identified associated factors point to subgroups that may be particularly at risk and establishes a foundational basis for targeted interventions and potential policy changes. Future research should incorporate longitudinal investigations and emphasize culturally sensitive assessments.

Complicated grief and posttraumatic stress after loss and separation under terror conditions

The lives of people in conflict areas are often characterized by the experience of traumatic events frequently accompanied by loss and separation. These can equally trigger symptoms of posttraumatic stress disorder (PTSD) and complicated grief (CG). The aim of the present study was to investigate whether affected individuals could be assigned to distinct classes at symptom-cluster levels of these two disorders. Moreover, we aimed to identify event-related and sociodemographic predictors associated with membership in these pathological classes. Participants were Iraqi internally displaced persons (IDPs; N = 199) who fled their hometowns due to the ISIS conflict and reported having lost an important person within the past 5 years. Based on the PTSD Checklist for DSM-5 (PCL-5) and Inventory of Complicated Grief (ICG), a latent class analysis (LCA) was applied to examine different classes of symptom clusters. Multinomial logistic regression was used to determine which variables predicted assignment to these symptom classes. The impact of loss and separation among IDPs in Iraq manifested in CG symptoms in more than half of the affected population and was often accompanied by PTSD. LCA identified a low-symptoms class (17.6%), CG class (33.7%), PTSD class (12.1%), and comorbid PTSD+CG class (36.7%). The sudden or violent death of a loved one was identified as a distinguishing factor for PTSD. Furthermore, separation was associated with comorbidity. Aid agencies should take these specific factors into account to improve effective and economic aid delivery to IDPs continuously affected by terror.

"I Have No Words": A Qualitative Study About the Traumatic Experience of Violent Death

Individuals bereaved by violent death have a higher risk of developing psychopathology. Consistent data concerning the subjective experience during the traumatic event of the death are still scarce. This study aimed to explore the traumatic experience of the violent death of a loved one. Nine reports of patients bereaved by violence were selected and transcribed. Reports were analyzed using Bardin's Content Analysis. Two final categories were generated. It was observed that most participants remembered details about the traumatic event or the time they were told about the violent death. There were two factors described as important when coping with the loss, social support during the traumatic event, and receiving detailed information from the authorities and others present in that moment. This study provides relevant data for future interventions during violent situations by health and security professionals.

Self-guided online treatment of disturbed grief, posttraumatic stress, and depression in adults bereaved during the COVID-19 pandemic: A randomized controlled trial

OBJECTIVE

This randomized-waitlist controlled trial is the first study examining short-term effects of a self-guided online grief-specific cognitive behavioral therapy (CBT) in reducing early persistent complex bereavement disorder (PCBD), posttraumatic stress disorder (PTSD), and depression symptoms in adults bereaved during the COVID-19 pandemic.

METHOD

Sixty-five Dutch adults, bereaved at least three months earlier during the pandemic, with clinically-relevant PCBD, PTSD, and/or depression symptoms, were allocated to a treatment (n = 32) or waitlist condition (n = 33). Telephone interviews were conducted to assess PCBD, PTSD, and depression symptoms (using validated instruments) at baseline, post-treatment, and post-waiting period. Participants received an eight-week self-guided online grief-specific CBT including exposure, cognitive restructuring, and behavioral activation assignments. Analyses of covariance were performed.

RESULTS

Intention-to-treat analyses indicated that people in the intervention condition showed significantly lower PCBD (d = 0.90), PTSD (d = 0.71), and depression (d = 0.57) symptom-levels post-treatment relative to waitlist controls post-waiting, while taking baseline symptom-levels and use of professional psychological co-intervention into account.

CONCLUSIONS

The online CBT proved to be an effective intervention, reducing PCBD, PTSD, and depression symptoms. Pending replication of these findings, early online interventions may be widely implemented in practice to improve treatments for distressed bereaved people.

Prolonged grief, post-traumatic stress, and functional impairment in parents and siblings 8 years after the 2011 Utøya terror attack

Background: Research on bereavement after terrorism is limited and primarily aiming on short-term consequences.Objective: To better understand the long-term health consequences of terrorism, we studied bereaved parents and siblings eight years after the Utøya terrorist attack in Norway. We examined the participants' symptom levels of prolonged grief (PG) and post-traumatic stress (PTS), as well as their psychosocial functioning and employment status.Method: Bereaved parents (n = 88) and siblings (n = 34) aged 19 and above (mean age  = 49.7 years, SD = 13.8 years, 59.8% female) completed the Inventory of Complicated Grief (ICG), the Impact of Event Scale-Revised (IES-R), and the Work and Social Adjustment Scale (WSAS) to assess PG, PTS, and functional impairment, respectively. In addition, information about employment status was obtained. The proportion of participants scoring above recommended thresholds on the ICG, IES-R, and WSAS was calculated. Differences between parents and siblings and gender differences on these measures were examined.Results: In total, 62.3% of the participants had scores on the ICG indicating a risk for prolonged grief, while 45.9% scored over cutoff on the IES. There was a high overlap between symptoms of PG and PTS. Females had significantly higher scores on both the ICG and the IES compared to males. There were no differences between parents and siblings regarding PG and PTS symptoms. One out of three showed severe functional impairment on the WSAS. Approximately 30% of all the bereaved were outside the labour force, and one third of the parents had become unable to work after the terrorist attack.Conclusion: Many bereaved parents and siblings, following the Utøya terror attack, report long-lasting health consequences with symptoms of PG and PTS and functional impairment. The results suggest a need for follow up of bereaved after a terror attack and identify family members in need of health services.

How symptoms of prolonged grief disorder, posttraumatic stress disorder, and depression relate to each other for grieving ICU families during the first two years of bereavement

Background

Bereaved ICU family surrogates are at risk of comorbid prolonged grief disorder (PGD), posttraumatic stress disorder (PTSD), and depression. Knowledge about temporal relationships between PGD, PTSD, and depression is limited by a lack of relevant studies and diverse or inappropriate assessment time frames given the duration criterion for PGD. We aimed to determine the temporal reciprocal relationships between PGD, PTSD, and depressive symptoms among ICU decedents’ family surrogates during their first 2 bereavement years with an assessment time frame reflecting the PGD duration criterion.

Methods

This prospective, longitudinal, observational study examined PGD, PTSD, and depressive symptoms among 303 family surrogates of ICU decedents from two academic hospitals using 11 items of the Prolonged Grief Disorder-13, the Impact of Event Scale—Revised, and the depression subscale of the Hospital Anxiety and Depression Scale, respectively, at 6, 13, 18, and 24 months post-loss. Cross-lagged panel modeling was conducted: autoregressive coefficients indicate variable stability, and cross-lagged coefficients indicate the strength of reciprocal relationships among variables between time points.

Results

Symptoms (autoregressive coefficients) of PGD (0.570–0.673), PTSD (0.375–0.687), and depression (0.591–0.655) were stable over time. Cross-lagged standardized coefficients showed that depressive symptoms measured at 6 months post-loss predicted subsequent symptoms of PGD (0.146) and PTSD (0.208) at 13 months post-loss. PGD symptoms did not predict depressive symptoms. PTSD symptoms predicted subsequent depressive symptoms in the second bereavement year (0.175–0.278). PGD symptoms consistently predicted subsequent PTSD symptoms in the first 2 bereavement years (0.180–0.263), whereas PTSD symptoms predicted subsequent PGD symptoms in the second bereavement year only (0.190–0.214). PGD and PTSD symptoms are bidirectionally related in the second bereavement year.

Conclusions

PGD, PTSD, and depressive symptoms can persist for 2 bereavement years. Higher PGD symptoms at 6 months post-loss contributed to the exacerbation of PTSD symptoms over time, whereas long-lasting PTSD symptoms were associated with prolonged depression and PGD symptoms beyond the first bereavement year. Identification and alleviation of depression and PGD symptoms as early as 6 months post-loss enables bereaved surrogates to grieve effectively and avoid the evolution of those symptoms into long-lasting PGD, PTSD, and depression.

Predictors of prolonged grief disorder in Chinese elderly shidu parents: The role of perceived stigma and perceived stress

INTRODUCTION

Parents who have lost their only child and over the age of 60 are known as elderly shidu parents. This study aimed to investigate predictors of prolonged grief disorder (PGD) among Chinese elderly shidu parents.

METHODS

Two hundred and ninety-eight elderly shidu parents from Shenyang were included in this cross-sectional study. Participants completed a questionnaire including the Prolonged Grief questionnaire-13 (PG-13), the PTSD (post-traumatic stress disorder) Checklist for DSM-5 (PCL-5), the Center for Epidemiologic Studies Depression Scales (CES-D), the Self-Rating Anxiety Scale (SAS), and the Perceived Stress Scale-10 (PSS-10). Multiple linear regression was used to examine socio-demographic, bereavement-related and perceived stress associated with PGD symptoms.

RESULTS

The prevalence of PGD among Chinese elderly shidu parents was 13.8%. Among the 41 PGD patients, 29, 39, 36 patients had comorbidity of PTSD, depressive symptoms and anxiety, respectively. Perceived stress, higher educational level, lower annual household income, perceived stigma, violent death of the child, and being in debt were associated with severer PGD symptoms.

DISCUSSION

The present study revealed the prevalence of PGD and the important role of PGD in diagnosing other mental disorders in Chinese elderly shidu parents. Providing financial help, eliminating social stigma, and stress should be included in PGD prevention among Chinese elderly shidu parents.

Prolonged grief in refugees living in Germany confronted with ambiguous or confirmed loss

BACKGROUND AND OBJECTIVES

People often disappear in the context of displacement or armed conflicts. Although such an ambiguous loss is accompanied by persistent uncertainty about the whereabouts, the psychological consequences are not well understood. This study investigated the effects of ambiguous compared to a confirmed loss on prolonged grief disorder (PGD) and its correlates in refugees to Germany.

METHODS AND DESIGN

We investigated data on mental health outcomes of refugees from Syria, Iraq, Iran and Afghanistan who had applied for/were granted asylum in Germany. In a secondary analysis, we compared 87 refugees with disappeared (n = 33) and deceased relatives (n = 54) who had completed questionnaire-based interviews.

RESULTS

Participants with ambiguous loss displayed more severe symptoms of PGD than those with confirmed loss. However, we found no group differences in terms of probable disorder rates and the number of traumatic experiences. Even after controlling for several correlates of PGD, higher PGD symptom severity was associated with ambiguous loss, more PTSD symptoms and low perceived social support.

CONCLUSIONS

These results show a higher prolonged grief symptom severity after the loss of a significant other due to disappearance, indicating that this type of loss could be a specific risk factor for PGD severity.

Loss and bereavement in late life (60+): Study protocol for a randomized controlled trial regarding an internet-based self-help intervention

BACKGROUND

The death of a close person is a highly stressful, yet common life event in later life. While most individuals seem to cope well with bereavement, a substantial proportion of older individuals suffer from prolonged grief symptoms. E-mental health interventions have been shown to be efficient for a variety of psychological illnesses. Yet, there is a large research gap of studies with a special focus on older adults. This study protocol describes a randomized controlled trial for an internet-based self-help intervention addressing bereavement and loss in adults aged 60 years and over. The self-management intervention is based on techniques of cognitive behavioral therapy and consists of 8 modules. The objective of the AgE-health study is to evaluate the effectiveness and acceptability of this intervention in comparison to a bibliotherapy control group.

METHODS

The AgE-health study aims at implementing a randomized controlled trial. Eligible participants aged 60+ years will be randomly allocated to an intervention group (access to the intervention) or to an active control group (access to bibliotherapy). Primary outcome is the reduction in grief symptoms (13-item Prolonged Grief Inventory); secondary outcomes are depression, social activity and network, quality of life, self-efficacy, satisfaction with the intervention/bibliotherapy, loneliness, acceptability, up-take and adherence. Assessments will take place before the intervention (baseline) as well as 4 months (follow-up 1) after the intervention.

DISCUSSION

This study addresses an under-recognized and understudied mental health burden in later life and may add valuable insight into our knowledge about the effectiveness of eHealth interventions for loss and bereavement in late life. To our knowledge, the AgE-health study will be the first randomized controlled trial to evaluate the effectiveness of an internet-based intervention targeting prolonged grief in adults aged 60 years and over.

TRIAL REGISTRATION

The study has been registered at the German Clinical Trials Register (Identifier: DRKS00020595, Registered 30th July 2020, https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00020595).

The role of post-loss anxiety in the development of depressive symptoms and complicated grief symptoms: a longitudinal SEM study

BACKGROUND

Though grief, anxiety, and depression often co-occur, existing evidence mostly focus on any two of them at a time. Our study examined the relationships among the three clusters of symptoms.

METHODS

A Chinese community sample of 101 bereaved individuals participated at T1. We utilized Bayesian Structural Equation Modelling (BSEM) to conduct cross-lagged analyses on three-wave panel data (T1 at one-month post-loss, T2 at four-months, and T3 at seven-months).

RESULTS

BSEM findings confirmed the presence of distinctive developmental paths for complicated grief (CG), anxiety, and depressive symptoms. Three simplex models showed that anxiety, CG symptoms, and depressive symptoms maintained high consistency. In cross-lagged models, anxiety at T1 was a significant predictor of depressive symptoms (standardized estimate B=0.386*) and CG symptoms (standardized estimate B=0.300*) at T2. The remaining positive directions (0.338*, 0.256*) in the final model suggest the important role of anxiety at early bereavement, while at a later stage, T2 CG contributed to depressive symptoms at T3 (0.356*).

LIMITATIONS

In addition to attrition, the overall sample size was limited. Data were based on self-report. Future research with repeated measures and Bayesian informative priors would be more useful to establish relational patterns of symptoms.

CONCLUSIONS

In our models, the reduction in anxiety symptoms contributed to the development of depressive and CG symptoms, and these results should be replicated. Theories of mechanisms underlying post-loss anxiety can be explored as a potential means of reducing later symptoms.

Mothers' emotions after pediatric burn injury: Longitudinal associations with posttraumatic stress and depressive symptoms 18 months postburn

BACKGROUND

Various emotions are implicated in posttraumatic stress disorder (PTSD). Longitudinal studies examining temporal associations between emotions and posttraumatic stress may reveal who is at risk of chronic psychological problems. This study examined the longitudinal relationships of mothers' trauma-related emotions with posttraumatic stress and depressive symptoms after pediatric burn injury.

METHODS

Data from two cohort studies were used (n = 296). Mothers reported the intensity of burn-related emotions within the first month (T1) and 12 months postburn (T2). The Impact of Event Scale (IES) and the Hospital and Anxiety Depression Scale (HADS-D; depression subscale) were administered at T1 and 18 months postburn (T3).

RESULTS

Based on two exploratory factor analyses, emotion variables were combined into acute and long-term basic emotions (fear, sadness, horror, anger) and self-conscious emotions (guilt, shame). The path model showed a positive relationship between acute and long-term basic emotions. Higher long-term basic emotions were related to persistence of posttraumatic stress and depressive symptoms. Acute self-conscious emotions showed associations with posttraumatic stress and depressive symptoms at T1 and were longitudinally related to depressive, but not posttraumatic stress, symptoms.

LIMITATIONS

The posttraumatic stress measure was not based on DSM-5 PTSD criteria and results require replication using these criteria.

CONCLUSIONS

This study suggests that mothers' acute self-conscious and long-term basic emotions in relation to their child's burn injury are involved in the development of posttraumatic stress and depressive symptoms. Clinically, assessing and monitoring parents' early posttraumatic stress, depressive symptoms and burn-related emotions may be useful to identify parents at risk.

Risk factors for PTSD of Shidu parents who lost the only child in a rapid aging process: a cross-sectional study

BACKGROUND

The elderly population is rising globally, especially in China where a large population base causes the largest number of older adults in the world. Notably, Shidu people who are over the age of 60 and have lost their only child have drawn great public attentions as they become more elderly, medically unstable and worse mentally unhealthy. Posttraumatic stress disorder (PTSD) is one of the most common consequences resulted from the loss of the only child. However, few previous studies have examined PTSD in Shidu older aldults, and the risk factors are a relatively understudied area. Our study aims to estimate the prevalence and potential risk factors of PTSD and improve the possibility of early identifying the high-risk Shidu parents with PTSD, and successively provide timely and effective interventions.

METHOD

Based on the register of population statistic information provided by the health family planning commission, 149 participants were enrolled randomly. Data was collected by interviews and questionnaires. Socio-demographic and bereavement-related information and physical health outcomes were obtained. PTSD Checklist-Civilian Version was used to screen for bereavement-related PTSD.

RESULT

The morbidity of PTSD reached 30.9%, while in the group of age over 60 the morbidity reached 31.6%. Stratified by potential demographic risk factors, SDPs have significant between-group differences of PTSD. Specially, being women, higher income, losing the single child at older age, more serious medical conditions and being Shidu for a shorter period indicated higher severity of PTSD in SDPs. The single child dying at a older age and from accidence were also significant indicators. Regression analysis showed the gender of SDPs, hospital visits, and the cause of child death significantly predicted the severity of PTSD.

CONCLUSION

With the accelerate process of aging, especially in China, Shidu older adults become a group deserved more attentions. PTSD is clearly a possible reaction to the loss of the only child. The gender and hospital visits of the Shidu older adults and the causes of their child's death significantly related to the prevalence of PTSD, which could help to improve the possibility of early intervening.

Symptoms of prolonged grief and major depressive disorders: Distinctiveness and temporal relationship in the first 2 years of bereavement for family caregivers of terminally ill cancer patients

OBJECTIVE

Prolonged grief disorder (PGD) and major depressive disorder (MDD) are common syndromes shaping bereaved caregivers' quality of life (QOL). However, distinctiveness of these syndromes warrants confirmation, and the temporal relationship of PGD and MDD symptoms has not been established. To fill these knowledge gaps, we conducted this longitudinal study.

METHODS

PGD symptoms, depressive symptoms, and psychological QOL were measured over 398 caregivers' first 2 years of bereavement using the Prolonged Grief-13 (PG-13) scale, Center for Epidemiologic Studies-Depression (CES-D) scale, and Short Form-36 Health Survey mental health summary, respectively. To clarify the distinctiveness of PGD and MDD symptoms, we examined their associations with psychological QOL by incremental validity testing. Distinctiveness and temporal relationship of PGD and MDD symptoms were also examined using longitudinal, lower-level mediation analysis with a lagged approach.

RESULTS

After the variance in psychological QOL was explained by CES-D scores (pseudo-R² = 44.19%, P < .001), PG-13 scores significantly, incrementally increased the explained variance in psychological QOL (pseudo-R² = 0.21%, P < .001), confirming the distinctiveness of PGD and MDD symptoms. CES-D scores mediated 40.7% of the time vs PG-13 score relationship, whereas PG-13 scores mediated 78.2% of the time vs CES-D score relationship with a better model fit, indicating that PG-13 scores assessed earlier mediated caregivers' current depressive status rather than vice versa.

CONCLUSIONS

PGD and MDD are distinct constructs, and PGD precedes onset of MDD. Clinicians should distinguish between these two disorders and address bereaved caregivers' PGD to reduce PGD-associated distress and morbidity and to prevent MDD onset, thereby improving their QOL.

Different Trajectories of Prolonged Grief in Bereaved Family Members After Terror

Introduction: The loss of a loved one in a terror incident is associated with elevated risk for mental health disorders such as prolonged grief disorder (PGD) and posttraumatic stress disorder (PTSD), but the long- term adaptation after such losses are not well understood. This study aims to explore the trajectories of PGD among parents and siblings (n = 129) after the 2011 terror attack on Utøya Island, Norway. Methods: The 19-item Inventory of Complicated grief (ICG) was used to measure PGD at 18, 28, and 40 months post-loss. Latent class growth analysis (LCGA) was used to identify trajectories of grief and a multinomial regression analysis was conducted to examine predictors of class membership. Results: The analysis identified three grief trajectories; moderate/decreasing class (23%), high/slow decreasing class (64%), and a high/chronic class (13%). Predictors of high/slow recovery or chronic grief was female gender, previous depressive symptoms, and intrusion and avoidance symptoms. Conclusion: The findings highlights the difficult grief process and slow recovery that characterizes the majority of close family members bereaved by a terror-incident. Community mental health programs should strive for both early outreach and long-term follow-up after such incidents.

Symptomatology following loss and trauma: Latent class and network analyses of prolonged grief disorder, posttraumatic stress disorder, and depression in a treatment-seeking trauma-exposed sample

BACKGROUND

Although bereavement is likely a common stressor among patients referred to a psychotrauma clinic, no study has yet examined the co-occurrence and relationships between symptoms of prolonged grief disorder (PGD), posttraumatic stress disorder (PTSD), and major depressive disorder symptoms in this population.

METHOD

In a sample of patients seeking treatment following psychological trauma (n = 458), we used latent class analysis to identify classes of patients sharing the same profile of PGD, PTSD, and depression symptoms. We then used network analysis to investigate the relationships among these symptoms and with loss-related variables.

RESULTS

Most participants (65%) were members of a class that exhibited elevated endorsement of PGD symptoms. PGD, PTSD, and depression symptoms hung together as highly overlapping but distinguishable communities of symptoms. Symptoms related to social isolation and diminished sense of self bridged these communities. Violent loss was associated with more difficulty accepting the loss. The loss of close kin was most strongly associated with difficulty moving on in life.

CONCLUSIONS

PGD symptoms are common in trauma-exposed bereaved adults and closely associated with symptoms of PTSD and depression, illustrating the importance of assessing bereavement and PGD symptoms in those seeking treatment following trauma.

Posttraumatic Symptoms and Change of Complicated Grief among Bereaved Families of the Sewol Ferry Disaster: One Year Follow-up Study

BACKGROUND

The objective of this study was to determine whether severity and severity change of coexisting psychiatric symptoms might affect change of complicated grief (CG) regarding the Sewol ferry disaster.

METHODS

Data from a cross-sectional survey were obtained 18 months (Time 1) and 30 months (Time 2) after the disaster. We ascertained sociodemographic variables and variables obtained from self-reporting questionnaires (i.e., CG, depression, anxiety, post-traumatic stress disorder [PTSD], insomnia, embitterment, and suicidal risk) among 56 bereaved family members.

RESULTS

Severity of other psychiatric symptoms at Time 1 had no effect on change of CG at Time 2. However, changes in severity of PTSD over a year affected change of CG.

CONCLUSION

It is important to evaluate changes in severity of PTSD and its treatment during management of CG, especially when it involves bereaved families experiencing a traumatic accident.

Predictors of Outcome and Residual Symptoms Following Trauma-Focused Psychotherapy in Police Officers With Posttraumatic Stress Disorder

Police officers exposed to potentially traumatic events (PTE) are at a heightened risk of developing posttraumatic stress disorder (PTSD). Little is known about trauma-focused psychotherapy outcomes in the police. In this naturalistic study, we evaluated whether PTE exposure and baseline clinical characteristics predicted PTSD symptom reduction during treatment and residual PTSD symptoms posttreatment. In consecutive referrals to a specialized mental health service for police officers (N = 665), PTSD was measured pre- and posttreatment using structured clinical interviews. Treatment consisted of brief eclectic psychotherapy for PTSD. We grouped PTE as follows: injury/maltreatment, loss (colleague or private), other job-related, other private traumatic events. Data were analyzed multivariably using structural equation modeling and logistic regression. Treatment effect size was large, d = 3.6, 95% CI [3.4, 3.8]. Police officers who reported more injury/maltreatment or private traumatic had more baseline PTSD symptoms as well as larger symptom reduction during treatment; police officers who reported more losses of loved ones showed smaller PTSD symptom reduction. Concentration problems persisted in 17.7% of police officers posttreatment, and these were predicted by baseline PTSD symptoms and loss of loved ones. Proportions of variance explained by the multivariable models ranged from 0.08 to 0.14. Our findings increase insight into the type of PTE and clinical characteristics of police officers with PTSD who benefit most from trauma-focused treatment. Because loss of loved ones can be presumed to have a profound impact on social and interpersonal functioning, a more specific treatment focus on grief processes may further enhance efficacy.

Supporting Parent Caregivers of Children with Life-Limiting Illness

The well-being of parents is essential to the well-being of children with life-limiting illness. Parents are vulnerable to a range of negative financial, physical, and psychosocial issues due to caregiving tasks and other stressors related to the illness of their child. Pediatric palliative care practitioners provide good care to children by supporting their parents in decision-making and difficult conversations, by managing pain and other symptoms in the ill child, and by addressing parent and family needs for care coordination, respite, bereavement, and social and emotional support. No matter the design or setting of a pediatric palliative care team, practitioners can seek to provide for parent needs by referral or intervention by the care team.

Treating complicated grief and posttraumatic stress in homicidally bereaved individuals: A randomized controlled trial

Homicidally bereaved individuals may experience symptoms of Complicated Grief (CG) and Posttraumatic Stress Disorder (PTSD). This Randomized Controlled Trial examined the effectiveness of an 8-session treatment encompassing Cognitive Behavioural Therapy (CBT) and Eye Movement Desensitization and Reprocessing (EMDR) to reduce self-rated CG and PTSD symptoms in 85 Dutch adult homicidally bereaved men and women. We compared changes in symptoms of CG (assessed using the Inventory of Complicated Grief) and PTSD (assessed using the Impact of Event Scale) between an intervention group and a waitlist control group. The treatment was effective in reducing CG and PTSD symptoms, from pretreatment to posttreatment. It can be concluded that EMDR and CBT seem promising treatments for homicidally bereaved individuals for both men and women, and regardless of the time since the loss. Further research is needed to examine whether a combined treatment of EMDR and CBT together is of added value in situations where grief and trauma are intertwined over offering only one of the two treatment modalities.
