Co-occurrence of approach and avoidance in prolonged grief: a latent class analysis

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.

Purpose: Prolonged grief, a severe and chronic form of grieving most commonly studied in the context of bereavement, may have relevance to losses associated with chronic illness (e.g. grief related to loss of functioning or loss of a planned future). The purpose of the present study is to examine the unique associations between prolonged grief symptoms and service utilization patterns. Methods: An online self-report assessment battery was administered among a sample of 275 older adults with at least one chronic illness that caused significant physical impairment. Results: Even after statistically controlling for relevant physical health (e.g. severity of physical limitations, somatic symptoms, number of chronic illnesses) and psychosocial variables (e.g. social support, depression/anxiety), more severe prolonged grief symptoms were associated with a greater number of emergency room visits, overnight stays in the hospital and total nights in the hospital. Conclusions: These findings highlight the importance of screening for prolonged grief symptomatology with older individuals with a debilitating chronic illness.Implications for RehabilitationRecent evidence suggests that prolonged grief may have relevance for losses associated with physical illness.The present study shows that prolonged grief reactions related to physical illness (e.g. grieving the loss of functioning) are uniquely associated with increased hospital-based service utilization.Given the relevance of prolonged grief reactions in this population, practitioners may wish to assess for these symptoms.Future clinical research should focus on developing interventions to target prolonged grief symptoms associated with these losses.

A minority of bereaved individuals develops severe, persistent, and disabling grief, termed “prolonged grief.” 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) include such grief reactions as prolonged grief disorder (PGD). Loneliness is often experienced by bereaved persons and can have severe health consequences. Preliminary research suggests that loneliness may perpetuate grief, but prolonged grief may also aggravate loneliness. Since existing empirical research provides limited information on temporal relationships between both constructs, we aimed to fill this gap in knowledge. Bereaved adults (88% female, mean age 54 years) filled in questionnaires assessing general, social, and emotional loneliness and prolonged grief and depression symptoms across two time points, 6 months apart. Cross-lagged panel model analyses showed that prolonged grief symptoms predicted more severe general, social, and emotional loneliness, as well as more depression symptoms. Loneliness did not predict prolonged grief symptoms and depression symptoms. Depression symptoms did not predict prolonged grief symptoms and loneliness. Additionally, latent change score analyses demonstrated that within person changes in prolonged grief symptoms and loneliness were related. Findings are inconsistent with the notion that loneliness causes prolonged grief and depression. Possibly, severe grief could lead to stigmatization, reduced social support, and feeling socially disconnected, perpetuating loneliness and depression symptoms.

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). 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. 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. 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.

Prolonged grief reactions after old age spousal loss and centrality of the loss in post loss identity

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.

Prolonged grief disorder, a condition characterized by severe, persistent, and disabling grief, is newly included in ICD-11 and DSM-5-TR. Prolonged grief symptoms can be effectively treated with face-to-face or internet-delivered cognitive behavioral therapy. Traumatic losses may elicit higher prevalence of severe grief reactions. While face-to-face cognitive behavioral therapy appears efficacious in treating prolonged grief symptoms in traumatically bereaved individuals, it is not yet clear if internet-based cognitive behavioral therapy is efficacious for this population. Therefore, we investigated the efficacy of a 12-week internet-delivered cognitive behavioral therapy for people bereaved through traffic accidents in a randomized waitlist-controlled trial (registration number: NL7497, Dutch Trial Register). Forty adults bereaved though a traffic accident were randomized to internet-based cognitive behavioral therapy (n = 19) or a waitlist control condition (n = 21). Prolonged grief, post-traumatic stress, and depression symptoms were assessed at baseline, post-treatment, and 8-week follow-up. Dropout in the treatment condition was relatively high (42%) compared to the control condition (19%). Nevertheless, multilevel analyses showed that internet-based cognitive behavioral therapy strongly reduced prolonged grief, post-traumatic stress, and depression symptoms relative to the control condition at post-treatment and follow-up. We conclude that internet-based cognitive behavioral therapy appears a promising treatment for traumatically bereaved adults.

Prolonged grief symptoms often co-occur with depressive and posttraumatic stress (PTS) symptoms, but the temporal relationships between prolonged grief symptoms and other postloss psychopathology symptoms are not well understood. Insights into the temporal relationships can inform treatment decisions for bereaved adults. Therefore, we aimed to clarify these temporal relationships. Three-hundred seven bereaved adults within their first bereavement year (78% female) completed questionnaires to assess prolonged grief, depressive, and PTS symptoms at five time points at 1.5-month intervals. Random-intercept cross-lagged panel modeling was utilized to inspect reciprocal relationships between these symptoms. Higher prolonged grief symptoms than usual predicted other psychopathology symptoms and vice versa across at least one interval in all bivariate models. In a model including prolonged grief, depressive, and PTS symptoms, within-person fluctuations in acute grief (i.e., grief occurring between 0 and 6 months after loss) levels predicted other postloss symptoms but not vice versa. Most variance could be attributed to stable differences between individuals. Future research should examine the clinical utility of targeting acute grief reactions to prevent the emergence of other postloss psychopathology.

Prior studies have shown that pre-loss closeness and conflict with a deceased person are associated with the severity of symptoms of prolonged grief and/or depression. Nevertheless, mechanisms underlying these relationships are not well understood. We propose a theoretical model in which past closeness and conflict are related to prolonged grief and depression via concrete and symbolic continuing bonds (CB). The aim of our study was to test this model in a sample of bereaved family members. Individuals (N = 244) who had lost a family member from 0.5 to 8.0 years before the survey completed the Quality of Relationships Inventory-Bereavement Version, the Continuing Bonds Scale, the Prolonged Grief Disorder-13 scale, and the Patient Health Questionnaire-9. The findings partially confirmed our model. Closeness was positively and moderately associated with symptoms of prolonged grief but not with symptoms of depression. Conflict was positively and weakly associated with symptoms of depression and prolonged grief. All of these relationships were only partially mediated by concrete/maladaptive and symbolic/adaptive CB. The differences in the relationship of past closeness and conflict to prolonged grief and depression symptoms suggest that inter- and intrapersonal mechanisms of prolonged grief and depressive symptoms may be distinct. If future, especially longitudinal studies, confirm our model, CB would be a possible target for interventions for bereaved persons who had a close and/or conflicted relationship with a deceased family member and experience loss-related psychopathology. Continuing bonds (CB) are a potential target of interventions for bereaved persons who had a close and/or conflicted relationship with a deceased family member and experience symptoms of prolonged grief and/or depression. Internalization of the capacity to care for yourself and feel autonomous in a safe and stable therapeutic relationship may lead to increased self-confidence, promote working through past experiences in the relationship with the deceased, and gradual reduction of concrete forms of CB. Increasing awareness and acceptance of emotional experiences may contribute to the appreciation of past relationship with a deceased person and the growth of symbolic forms of CB. Future research should focus on verifying the effectiveness of the attachment-informed therapeutic approach to working with CB.

Background: In China, bereaved parents who have lost their only child are known as Shidu parents, and they tend to present high levels of prolonged grief reactions. To date, a widespread focus has been placed on positive social support, while potential negative experiences have been relatively neglected. Additionally, the role of social support from different sources (i.e. close family members [partner, siblings, grandchildren], peers, and others [relatives, friends, colleagues]) has not been examined thoroughly. Objective: The present study investigated whether social support from different sources has a differential impact on postloss adaptation (i.e. prolonged grief and growth). The loss-orientated and restoration-orientated coping strategies of the dual process model were also tested for their mediating roles. Methods: A total of 277 Chinese Shidu parents were recruited to complete a series of questionnaires including social support from different sources, prolonged grief symptoms, posttraumatic growth, and dual process coping strategies. Correlation analyses, paired sample t tests and structural equation modelling were conducted. Results: More positive support were related to less prolonged grief symptoms and more posttraumatic growth, while more negative support was only related to more prolonged grief. Positive support from close family members and others was significantly related to prolonged grief/growth, and negative support from these sources was significantly positively associated with prolonged grief. Positive or negative support from people who shared a similar experience was unrelated to prolonged grief/growth. Positive and negative support were related to prolonged grief and growth through loss-oriented coping strategies. Conclusion: Overall, the present study indicated that positive and negative support experiences from different sources functioned differently in the recovery of Chinese Shidu parents and that loss-oriented coping played a mediating role. These findings highlight the importance of differentiating social support by traits in coping with grief and the crucial mediating role of loss-oriented coping. HIGHLIGHTS More positive support correlated with less prolonged grief and more growth, while more negative support correlated with more prolonged grief. Support from family members and friends was more potent than that from peers. Social Support correlated with prolonged grief/growth through loss-oriented coping.

Experiential avoidance moderates the association between motivational sensitivity and prolonged grief but not posttraumatic stress symptoms

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), now include prolonged grief disorder (PGD). Since criteria for PGD in both classification systems differ from prior proposed grief disorders and each other, the validation of a single instrument to screen for prolonged grief (PG) symptoms of both new diagnoses is critical for bereavement research and care. Therefore, we evaluated the psychometric properties of the Swedish version of the Traumatic Grief Inventory Self-Report Plus (TGI-SR+). Two-hundred and forty-eight bereaved parents completed questions about sociodemographic and loss-related variables, the TGI-SR+, and symptom measures of post-traumatic stress (PTS), depression and an older measure of PG symptoms, the Prolonged Grief Disorder-13 (PG-13). Confirmatory factor analyses showed that a one-factor model best fit DSM-5-TR and ICD-11 PG symptoms and the analyses of the internal consistency and inter-item correlations showed that these symptoms could be reliably assessed. In support of convergent validity, DSM-5-TR and ICD-11 PG symptoms correlated with symptoms of PTS, depression and PG assessed with the PG-13. In support of known-groups validity, DSM-5-TR and ICD-11 PG symptoms were higher among lower educated (vs. higher educated) participants and related negatively to time since loss. ROC analyses showed optimal cut-off score of ≥71 and ≥72 to determine probable caseness for DSM-5-TR and ICD-11 PGD, respectively. Results support the reliability and validity of the Swedish TGI-SR+ as a screening instrument for PG in research and bereavement care.

Peritraumatic distress and anxiety sensitivity are associated with complications in bereavement, including posttraumatic stress and prolonged grief reactions. The extent to which these factors interact to contribute to bereavement-related distress, however, remains unclear. This study investigates whether anxiety sensitivity moderates the association between peritraumatic reactions and posttraumatic stress and prolonged grief symptoms in a sample of young adults with a history of bereavement due to sudden, unexpected deaths. Participants were 606 undergraduate students recruited from two US universities. Results suggest that peritraumatic emotional and physical distress and anxiety sensitivity are all independently associated with both posttraumatic stress and prolonged grief reactions. Furthermore, the association between peritraumatic distress and prolonged grief, but not posttraumatic stress, is moderated by anxiety sensitivity. These findings point to several potentially important, clinically modifiable factors associated with a variety of bereavement-related mental health problems among a vulnerable group of grievers.

Prolonged Grief Disorder (PGD) was added as a new diagnosis to the Diagnostic and Statistical Manual of Mental Disorders 5 Text Revision (DSM-5-TR). Research on treatment interventions for PGD has focused primarily on adults. However, due to developmental differences, children and adolescents may experience grief differently than adults. There is a need to tailor interventions to children and adolescent populations, but there is a lack of consensus on best practices for treating PGD in these populations. The purpose of this study was to review existing interventions for PGD in children and adolescents to better inform clinicians working with this population. A systematic review was conducted through Google Scholar, APAPsychNet, and by following citations. Studies were reviewed for participant age, prolonged grief symptoms or diagnosis, intervention, and outcomes. Ten studies were included for review with eight interventions identified. Results for each intervention were found to be generally positive in reducing PGD symptoms. Interventions were grouped by modality including group treatments, hybrid treatments (combined group or individual therapy with family therapy), family treatment, and individual treatment. Cognitive Behavior Therapy (CBT), Attachment Theory and Multidimensional Grief Theory were common theoretical bases for interventions and all shared elements of psychoeducation and integrating knowledge about the loss with existing knowledge. Involvement of surviving parents in treatment was found to be a common element across most child and adolescent interventions and was not included in PGD treatment for adults. This review was limited in scope due to lack of research on child and adolescent populations for PGD treatment and heterogeneity of intervention types. However, preliminary findings support the efficacy of interventions for PGD in children and adolescents and highlight a key difference in treatment for these populations.

Individuals vary in how they respond to bereavement. Those who experience poor bereavement outcomes often report symptoms from more than one diagnostic category. This study sought to identify groups of individuals who share similar patterns of prolonged grief disorder and posttraumatic stress disorder symptoms to determine whether these profiles are differentially related to negative appraisals thought to contribute to prolonged grief disorder and posttraumatic stress disorder symptomatology. Participants were 185 bereaved adults. Latent class analysis was used to identify subgroups of individuals who showed similar patterns of co-occurrence of prolonged grief disorder and posttraumatic stress disorder symptoms. Multinomial regression was used to examine the extent to which appraisal domains and sociodemographic and loss factors predicted class membership. Latent class analysis revealed three classes of participants: a low symptom group, a high prolonged grief disorder symptom group, and a high prolonged grief disorder and posttraumatic stress disorder symptom group. Membership of the prolonged grief disorder group and prolonged grief disorder and posttraumatic stress disorder group was predicted by higher mean negative self-related appraisals. Demographic and loss-related factors did not predict group membership. These findings have implications for understanding co-occurrence of prolonged grief disorder and posttraumatic stress disorder symptoms following bereavement. Findings are consistent with theoretical models highlighting the importance of negative self-related beliefs in prolonged grief disorder.
