Dwelling in prolonged grief: Resting state functional connectivity during oxytocin and placebo administration.

Clinical theories of adaptation in bereavement highlight a need for flexible shifting between mental states. However, prolonged motivational salience of the deceased partner may be a complicating factor, particularly when coupled with perseverative thinking about the loss. We investigated how prolonged grief symptoms might relate to resting state functional brain network connectivity in a sample of older adults (n = 38) who experienced the death of a partner 6-36 months prior, and whether intranasal oxytocin (as a neuropeptide involved in pair-bonding) had differential effects in participants with higher prolonged grief symptoms. Higher scores on the Inventory of Complicated Grief (ICG) were associated with lower anticorrelation (i.e., higher functional connectivity) between the defaultretrosplenial - cingulo-operculardACC network pair. Intranasal oxytocin increased functional connectivity in the same defaultretrosplenial - cingulo-operculardACC circuit but ICG scores did not moderate effects of oxytocin, contrary to our prediction. Higher ICG scores were associated with longer dwell time in a dynamic functional connectivity state featuring positive correlations among default, frontoparietal, and cingulo-opercular networks, across both placebo and oxytocin sessions. Dwell time was not significantly affected by oxytocin, and higher prolonged grief symptoms were not associated with more variability in dynamic functional connectivity states over the scan. Results offer preliminary evidence that prolonged grief symptoms in older adults are associated with patterns of static and time-varying functional network connectivity and may specifically involve a default network-salience-related circuit that is sensitive to oxytocin.

The Relationship of Prolonged Grief Disorder Symptoms With Hemodynamic Response to Grief Recall Among Bereaved Adults.

OBJECTIVE: Bereavement is among the most impactful psychosocial stressors for cardiovascular health, and hypertensive episodes accompanying bereavement-related distress are one putative mechanism for this effect. The present study examined hemodynamic responses to the Grief Recall (GR), a promising method for studying the effects of acute grief on cardiovascular function, and the relationship of grief severity to blood pressure (BP) response. METHODS: N = 59 participants within 1 year of the loss of a close loved one completed the GR, a semistructured interview protocol for eliciting bereavement-related distress (a "grief pang") and cardiovascular response. Systolic (SBP) and diastolic BP (DBP) were measured at two time points: a) an attention-control baseline and (2) after a 10-minute GR interview. Baseline versus post-GR SBP and DBP differences (i.e., BP response) were measured. Grief severity was examined as a predictor of SBP and DBP response, as well as BP recovery. RESULTS: SBP and DBP increased significantly after GR (SBP, +21.10 mm Hg; DBP, +8.10 mm Hg). Adjusting for variables relevant to cardiovascular function and bereavement (antihypertensive medication use, days since death, gender, age), grief severity predicted the magnitude of increase after GR in SBP but not DBP. No relationship of grief severity and recovery was observed. CONCLUSIONS: The observed association between hemodynamic response and grief severity suggests a mechanistic contribution from hemodynamic effects of acute grief episodes to the cardiovascular impact of grief. This is the first study to show that increased symptoms of prolonged grief disorder are associated with an elevated SBP response. The GR may have further utility for research examining physiological responses to bereavement-related emotions.

Evaluating training needs in clinical psychology doctoral programs.

OBJECTIVE: Advances in clinical psychology must be accompanied by advances in training. This study assessed training content, quality, and needs during clinical psychology doctoral programs among current or past doctoral students. METHODS: Current or past clinical psychology doctoral students (N = 343) completed an anonymous survey assessing training experiences and needs. A descriptive-focused exploratory factor analysis (EFA) also examined whether common subgroups of academic interests emerged. RESULTS: Most participants reported that they sought training beyond required coursework, primarily in clinical training, cultural competency, and professional development, and reported having taken one or more unhelpful course, including discipline-specific knowledge requirements. Descriptive results from the EFA demonstrated common training areas of interest: diversity topics, biological sciences, clinical practice, and research methods. DISCUSSION: This study demonstrates that trainees and early career psychologists are aware of their nuanced and in some cases, unmet training needs. CONCLUSION: This work foregrounds the need to adapt extant training opportunities to support the next generation of clinical psychologists.

Implementing Psychological First Aid for Healthcare Workers During the COVID-19 Pandemic: A Feasibility Study of the ICARE Model.

Maintaining the resilience of healthcare workers (HCWs) during the protracted COVID-19 pandemic is critical as chronic stress is associated with burnout, inability to provide high-quality care, and decreased attentiveness to infection prevention protocols. Between May and July 2020, we implemented the ICARE model of psychological first aid (PFA) in a novel online (i.e., telehealth) format to address the psychological support needs of HCWs during the COVID-19 pandemic. We found that HCWs needed psychological support related to obtaining clear information about pandemic policies and guidelines, navigating new rules and responsibilities, and processing overwhelming and conflicting emotions. The HCWs in our program repeatedly expressed appreciation for the support we provided. Future directions include establishing online discussion forums, increasing opportunities for individual support, and training HCWs to provide peer support using PFA. This program has far-reaching potential benefit to HCWs and to society at large in the context of a pandemic.

Measuring double awareness in patients with advanced cancer: A preliminary scale development study.

BACKGROUND: Individuals with advanced cancer face the challenge of living meaningfully while also preparing for end of life. The ability to sustain this duality, called "double awareness," may reflect optimal psychological adaptation, but no psychometric scale exists to measure this construct. OBJECTIVES: The purpose of this study was to develop a novel scale to measure double awareness in patients living with advanced cancer. METHODS: Guided by best practices for scale development, this study addresses the first three of nine steps in instrument development, including domain clarification and item generation, establishment of content validity of the items, and pre-testing of the items with patients. RESULTS: Instrument development resulted in a 41-item measure with two dimensions titled "life engagement" and "death contemplation." Items retained in the measure displayed face validity and were found to be both acceptable by patients and relevant to their lived experience. SIGNIFICANCE OF RESULTS: The results of this scale development study will allow for full validation of the measure and future use in clinical and research settings. This novel measure of double awareness will have clinical utility and relevance in a variety of settings where patients with advanced cancer are treated.

Recruitment and retention in clinical and experimental bereavement research: Lessons learned from creating a research registry.

A small body of research investigates recruitment and retention of bereaved people in experimental and intervention research. The present study compares the effectiveness of different recruitment strategies implemented by a grief laboratory at a large state university in order to optimize recruitment efforts. The most effective method is letters sent to bereaved community members identified through online newspaper obituaries. Despite a small overall response rate, the large population from which to sample provides continuous accrual every month. Other methods include electronic/print media, community institution referrals, word of mouth and community outreach. Best practices for recruitment and retention are recommended.

Wish you were here: The Dutch, German, and English Yearning in Situations of Loss Short Form.

OBJECTIVE(S): Yearning, a hallmark of grief disorders, relates to rumination and potentially to cognitive avoidance. We developed an 8-item short form of the only existing validated yearning measure, the Yearning in Situations of Loss Scale (YSL), to improve its validity and administration ease. METHOD: Cross-sectional surveys were conducted among bereaved Dutch (N = 313) and German (N = 235) community samples and an American treatment-seeking sample (N = 95). All samples completed the YSL, and community samples additionally measures of rumination, loss-related avoidance, complicated grief (CG), and depression. RESULTS: A one-factor model provided a good fit to the YSL Short Form (YSL-SF) in the community samples. A two-factor structure (cognitive and emotional yearning)best fitted the YSL-SF in the treatment-seeking sample. YSL-SF scores correlated positively with rumination, loss-related avoidance, and with CG symptoms whilst controlling for rumination and loss-related avoidance. CONCLUSION: The YSL-SF appears an easy-to-administer and valid measure of yearning after bereavement.

Grief: A Brief History of Research on How Body, Mind, and Brain Adapt.

OBJECTIVE: Using an integrative view of psychology, neuroscience, immunology, and psychophysiology, the present review of literature curates the findings that have had an impact on the field of bereavement research and shaped its development. METHODS: Beginning with pivotal systematic descriptions of medical and psychological responses to the death of a loved one by Lindemann in the mid-1940s, this selective review integrates findings in bereavement research from studies that investigate medical outcomes after loss, their psychological predictors, and biopsychosocial mechanisms. RESULTS: Morbidity and mortality after the death of a loved one have long been a topic of research. Early researchers characterized somatic and psychological symptoms and studied immune cell changes in bereaved samples. More recent research has repeatedly demonstrated increased rates of morbidity and mortality in bereaved samples, as compared with married controls, in large epidemiological studies. Recent developments also include the development of criteria for prolonged grief disorder (also termed complicated grief). Newer methods, including neuroimaging, have observed that the greatest impact of the death of a loved one is in those who have the most severe psychological grief reactions. Research addressing the mechanisms tying bereavement to medical outcomes is relatively scarce, but differences in rumination, in inflammation, and in cortisol dysregulation between those who adapt well and those who do not have been offered with some evidence. CONCLUSIONS: Recommendations to propel the field forward include longitudinal studies to understand differences between acute reactions and later adaptation, comparing samples with grief disorders from those with more typical responses, and integrating responses in brain, mind, and body.

Maladaptive repetitive thought as a transdiagnostic phenomenon and treatment target: An integrative review.

OBJECTIVE: Maladaptive repetitive thought (RT), the frequent and repetitive revisiting of thoughts or internal experiences, is associated with a range of psychopathological processes and disorders. We present a synthesis of prior research on maladaptive RT and develop a framework for elucidating and distinguishing between five forms of maladaptive RT. METHOD: In addition to the previously studied maladaptive RT (worry, rumination, and obsession), this framework is used to identify two additional forms of maladaptive RT (yearning and interoceptive RT). We then present a review of extant psychotherapy intervention research targeting maladaptive RT, focusing both on specific empirically based treatment strategies, and also constructs within treatments that impact maladaptive RT. CONCLUSION: The paper concludes with recommendations for future basic and intervention research on maladaptive RT and related psychopathologies.

Disrupted prefrontal activity during emotion processing in complicated grief: An fMRI investigation.

Complicated Grief, marked by a persistent and intrusive grief lasting beyond the expected period of adaptation, is associated with a relative inability to disengage from idiographic loss-relevant stimuli (O'Connor and Arizmendi, 2014). In other populations, functional magnetic resonance imaging (fMRI) studies investigating the neural networks associated with this bias consistently implicate the anterior cingulate cortex (ACC) during emotion regulation. In the present study, twenty-eight older adults were categorized into three groups based on grief severity: Complicated Grief (n=8), Non-Complicated Grief (n=9), and Nonbereaved, married controls (n=11). Using a block design, all participants completed 8 blocks (20 stimuli per block) of the ecStroop task during fMRI data acquisition. Differences in neural activity during grief-related (as opposed to neutral) stimuli across groups were examined. Those with Complicated Grief showed an absence of increased rostral ACC (rACC) and fronto-cortical recruitment relative to Nonbereaved controls. Activity in the orbitofrontal cortex (x=6, y=54, z=-10) was significantly elevated in the Non-Complicated Grief group when compared to Nonbereaved controls. Post hoc analysis evidenced activity in the dorsal ACC in the Complicated Grief and Nonbereaved groups late in the task. These findings, supported by behavioral data, suggest a relative inability to recruit the regions necessary for successful completion of this emotional task in those with Complicated Grief. This deficit was not observed in recruitment of the orbitofrontal cortex and the rACC during processing of idiographic semantic stimuli in Non-Complicated Grief.

Absent but Not Gone: Interdependence in Couples' Quality of Life Persists After a Partner's Death.

Spouses influence each other's psychological functioning and quality of life. To explore whether this interdependence continues after a person becomes widowed, we tested whether deceased spouses' characteristics were associated with their widowed partners' later quality of life using couples drawn from a multinational sample of aging adults. Independent subsamples (ns = 221 and 325) were assessed before and after a spouse's death. Regressions revealed that deceased partners' quality of life prior to their death positively predicted their spouses' quality of life after the partners' death, even when we controlled for spouses' prior quality of life to account for environmental factors shared within couples. Further, widowed participants' quality of life was lower than nonwidowed couples' 2 years before and after their partners' death, but was equivalent 4 years prior. Finally, the strength of the association between partners' earlier quality of life and participants' later quality of life did not differ between widowed and nonwidowed participants. These findings suggest that interdependence in quality of life continues after one's partner has passed away.

Broadening the definition of resilience and "reappraising" the use of appetitive motivation.

Kalisch et al.'s PASTOR model synthesizes current knowledge of resilience, focusing on mechanisms as a common pathway to outcomes and highlighting neuroscience as a method for exploring this. We propose the model broaden its definition of resiliency to include positive indices of recovery, include positive affect as a mechanism, and approach motivation as distinct from overcoming aversive motivation.

What is "normal" in grief?

Research conducted over the past two decades has revealed that grief, a common phenomenon experienced by many people following the loss of a loved one, is rarely experienced as a steady progression from high acuity (intensity) to eventual resolution. Instead of this single "traditional" path, four distinct trajectories are supported by empirical data: resilience, chronic grief, depressed-improved, and chronic depression. Furthermore, a small subset of individuals never fully integrate the loss into their life, and continue to experience severe disruption in daily life many years after the loss event, a phenomenon known as Complicated Grief (CG). Continued empirical research will help further our understanding of the normative grief process and CG as a disorder. This information is crucial for informing clinicians of best practices when attending to those suffering from loss.

Detection of altered hippocampal morphology in multiple sclerosis-associated depression using automated surface mesh modeling.

Depression is very common in multiple sclerosis (MS) but the underlying biological mechanisms are poorly understood. The hippocampus plays a key role in mood regulation and is implicated in the pathogenesis of depression. This study utilizes volumetric and shape analyses of the hippocampus to characterize neuroanatomical correlates of depression in MS. A cross-section of 109 female patients with MS was evaluated. Bilateral hippocampi were segmented from MRI scans (volumetric T1 -weighted, 1 mm(3) ) using automated tools. Shape analysis was performed using surface mesh modeling. Depression was assessed using the Center for Epidemiologic Studies-Depression (CES-D) scale. Eighty-three subjects were classified as low depression (CES-D 0-20) versus 26 subjects with high depression (CES-D ≥ 21). Right hippocampal volumes (P = 0.04) were smaller in the high depression versus the low depression groups, but there was no significant difference in left hippocampal volumes. Surface rendering analysis revealed that hippocampal shape changes in depressed patients with MS were clustered in the right hippocampus. Significant associations were found between right hippocampal shape and affective symptoms but not vegetative symptoms of depression. Our results suggested that regionally clustered reductions in hippocampal thickness can be detected by automated surface mesh modeling and may be a biological substrate of MS depression in female patients.

Divergent gene expression responses to complicated grief and non-complicated grief.

The "widowhood effect" (i.e., morbidity/mortality in recently bereaved spouses) may be related to changes in immune function, but little is known about the impact of bereavement on gene transcription in immune cells. This study examined how Complicated Grief and Non-complicated Grief responses to bereavement differentially affect leukocyte gene expression. Genome-wide transcriptional profiling and bioinformatic analyses were completed on 63 older adults. Thirty-six of them had lost their spouse/partner on average 2years ago, and 27 were nonbereaved, married controls. Twelve of the bereaved participants met criteria for Complicated Grief. Compared to nonbereaved controls, bereavement (both Complicated Grief and Non-complicated Grief) was associated with upregulated expression of genes involved in general immunologic activation and a selective downregulation of genes involved in B lymphocyte responses. However, Complicated Grief and Non-complicated Grief differed markedly in their expression of Type I interferon-related transcripts, with Non-complicated Grief subjects showing substantial upregulation relative to nonbereaved controls and Complicated Grief subjects showing substantial downregulation. Bereavement significantly modulates immune function gene expression. The magnitude of bereavement-related distress (i.e., Complicated Grief vs. Non-complicated Grief) is linked to differential patterns of transcription factor activation and gene expression involved in innate antiviral responses. These findings provide a molecular framework for understanding the health effects of bereavement, as well as new insights into the particular gene modules that are most sensitive to the individual's psychological response to loss.

Atrophy in the supramarginal gyrus associated with impaired cognitive inhibition in grieving Chinese Shidu parents.

Background: The loss of an only child, known as Shidu in China, is a profoundly distressing experience, often leading to Prolonged Grief Disorder (PGD). Despite its impact, the structural brain alterations associated with PGD, potentially influencing cognitive impairments in Shidu parents, remain understudied.Objective: This study aims to identify brain structural abnormalities related to prolonged grief and their relation with cognitive inhibition in Shidu parents.Methods: The study included 40 Shidu parents and 42 non-bereaved participants. Prolonged grief was evaluated using the Prolonged Grief Questionnaire (PG-13). We employed voxel-based morphometry (VBM) and diffusion tensor imaging (DTI) to assess brain structural alterations and their correlation with cognitive inhibition, as measured by Stroop interference scores.Results: Findings suggest that greater prolonged grief intensity correlates with reduced grey matter volume in the right amygdala and the left supramarginal gyrus (SMG). Additionally, enhanced amygdala-to-whole-brain structural connectivity showed a marginal association with prolonged grief, particularly with emotional-related symptoms. Furthermore, a decrease in SMG volume was found to mediate the relation between prolonged grief and Stroop Time Inference (TI) score, indicating an indirect effect of prolonged grief on cognitive inhibition.Conclusions: The study provides insight into the neural correlates of prolonged grief in Shidu parents, highlighting the SMG's role in cognitive inhibition. These findings emphasise the need for comprehensive grief interventions to address the complex cognitive and emotional challenges faced by this unique bereaved population.

The Shidu parents had a delay in cognitive inhibition when performing the Stroop test, compared to the control group.Prolonged grief intensity was linked to decreased grey matter in the right amygdala and a potential increase in amygdala-to-whole-brain structural connectivity. These volumes were associated with prolonged grief symptoms related to emotions.A higher level of prolonged grief was also associated with reduced grey matter volume in the left supramarginal gyrus, mediating the relationship between prolonged grief and Stroop Time Inference score, which indicates cognitive inhibition.

Associations of religious and existential variables with psychosocial factors and biomarkers of cardiovascular risk in bereavement.

Bereavement increases in prevalence as people age and is associated with multiple psychological and health risks, including cardiovascular risk. Religious and existential variables may play an important role in the health impacts of bereavement. Theorized pathways linking religious and existential variables with health have suggested these associations are due to intermediary psychosocial variables, but have not been tested in bereavement. This research empirically tested these pathways in a bereaved population. In N = 73 adults within 1 year of bereavement (mean age = 64.36), this study examined associations between (1) religious and existential characteristics (religious and spiritual struggles, intrinsic religiosity, and existential quest) and intermediary psychosocial variables (depression, loneliness, and difficulties in emotion regulation), and between (2) intermediary psychosocial variables and bereavement-relevant health outcomes (self-reported health, change in health since last year, grief severity, and cardiovascular biomarkers). Cardiovascular biomarkers (heart rate, heart rate variability, and blood pressure) were collected before, during, and after a laboratory grief recall emotion elicitation. Anticipated associations between self-reported religious and existential characteristics and intermediary variables, and between intermediary variables and self-reported bereavement-relevant outcomes, were consistently observed. However, associations between intermediary variables and cardiovascular biomarkers were largely unobserved. This study examined the role of religious and existential variables in whole-person health after bereavement and is among the first to include biomarkers of cardiovascular risk. Results suggest that although religious and existential variables are associated with important bereavement-related outcomes, these associations may be "skin-deep," and extensions to cardiovascular functioning should be re-examined.

A pull to be close: The differentiating effects of oxytocin and grief stimulus type on approach behavior in complicated grief.

Theoretical models of complicated grief (CG) suggest that maladaptive motivational tendencies (e.g., perseverative proximity-seeking of the deceased; excessive avoidance of reminders) interfere with a person's ability to recover from their loved one's death. Due in part to conflicting evidence, little mechanistic understanding of how these behaviors develop in grief exists. We sought to (1) identify behavioral differences between CG and non-CG groups based on approach/avoidance bias for grief-, deceased-, and social-related stimuli, and (2) test the role of the neuropeptide oxytocin in shaping approach/avoidance bias. Widowed older adults with (n = 17) and without (n = 22) CG completed an approach/avoidance task measuring implicit bias for both personalized and non-specific grief-related stimuli (among other stimuli). In a double-blinded, randomized, counterbalanced design, each participant attended both an intranasal oxytocin session and a placebo session. Aims were to (1) identify differential effects of CG and stimulus type on implicit approach/avoidance bias [placebo session], and (2) investigate interactive effects of CG, stimulus type, and oxytocin vs. placebo on approach/avoidance bias [both sessions]. In the placebo session, participants in the non-CG group demonstrated an approach bias across all stimuli. Intranasal oxytocin had an overall slowing effect on the CG group's response times. Further, oxytocin decreased avoidance bias in response to photos of the deceased spouse in the CG group only. Findings support the hypothesis that oxytocin has a differential effect on motivational tendency in CG compared to non-CG, strengthening evidence for its role in CG. Findings also emphasize the need to consider differences in personalized vs. generic stimuli when designing grief-relevant tasks.
