ICU bereaved surrogates' comorbid psychological-distress states and their associations with prolonged grief disorder.

ABSTRACT:

Background/objective

Bereaved ICU family surrogates' psychological distress, e.g., anxiety, depression, and post-traumatic stress disorder (PTSD), is usually examined independently, despite the well-recognized comorbidity of these symptoms. Furthermore, the few studies exploring impact of psychological distress on development of prolonged grief disorder (PGD) did not consider the dynamic impact of symptom evolution. We identified surrogates' distinct patterns/states of comorbid psychological distress and their evolution over the first 3 months of bereavement and evaluated their associations with PGD at 6-month postloss.

Methods

A longitudinal observational study was conducted on 319 bereaved surrogates. Symptoms of anxiety, depression, PTSD, and PGD were measured by the anxiety and depression subscales of the Hospital Anxiety and Depression Scale, Impact of Event Scale-Revised scale, and the PGD-13, respectively. Distinct psychological-distress states and their evolution were examined by latent transition analysis. Association between psychological-distress states and PGD symptoms was examined by logistic regression.

Results

Three distinct comorbid psychological-distress states (prevalence) were initially identified: no distress (56.3%), severe-depressive/borderline-anxiety distress (30.5%), and severe-anxiety/depressive/PTSD distress (13.3%). Except for those in the stable no-distress state, surrogates tended to regress to states of less psychological distress at the subsequent assessment. The proportion of participants in each psychological-distress state changed to no distress (76.8%), severe-depressive/borderline-anxiety distress (18.6%), and severe-anxiety/depressive/PTSD distress (4.6%) at 3-month postloss. Surrogates in the severe-depressive/borderline-anxiety distress and severe-anxiety/depressive/PTSD-distress state at 3-month postloss were more likely to develop PGD at 6-month postloss (OR [95%] = 14.58 [1.48, 143.54] and 104.50 [10.45, 1044.66], respectively).

Conclusions

A minority of family surrogates of ICU decedents suffered comorbid severe-depressive/borderline-anxiety distress and severe-anxiety/depressive/PTSD symptoms during early bereavement, but they were more likely to progress into PGD at 6-month postloss.

Project description:ImportanceFamily surrogates of patients who die in an intensive care unit (ICU) are at risk of cooccurring prolonged grief disorder (PGD), posttraumatic stress disorder (PTSD), and depressive disorder during bereavement, but symptom trajectories are often explored individually.ObjectivesTo simultaneously examine and determine co-occurrence of PGD, PTSD, and depressive symptom trajectories.Design, setting, and participantsThis cohort study was conducted in ICUs of 2 Taiwanese medical centers from January 2018 to March 2020, with follow-up through July 2022. Participants included surrogates responsible for decision-making who provided data 6 to 24 months after the death of their loved one. Data were analyzed from August to December 2022.Main outcomes and measuresPGD was assessed with the 11 grief symptom items of the PG-13; PTSD, the Impact of Event Scale-Revised; and depressive symptoms, the depression subscale of the Hospital Anxiety and Depression Scale at 6, 13, 18, and 24 months after the death. Latent growth mixture modeling was conducted to identify distinct trajectories, and joint latent class analysis was used to assess joint patterns of trajectories.ResultsA total of 303 participants were included, with most younger than 56 years (207 participants [68.3%]), female (177 participants [58.4%]), and married (228 participants [75.2%]), and their relationship with the patient was mostly spouse (88 participants [29.0%]) or adult child (166 participants [54.8%]). Three trajectories were identified each for PGD, PTSD, and depressive symptoms. A resilience trajectory was predominant across PGD (253 participants [83.5%]), PTSD (250 participants [82.5%]), and depressive (200 participants [66.0%]) symptoms. Second most common was a recovery trajectory identified for PGD (36 participants [11.9%]) and PTSD (41 participants [13.5%]) symptoms, while for depressive symptoms, a moderate trajectory (72 participants [23.8%]) signified persistent moderate distress. A chronic trajectory characterized by persistently high distress was identified for PGD (14 participants [4.6%]) and depressive (31 participants [10.2%]) symptoms, whereas a unique delayed-onset trajectory (12 participants [4.0%]) was identified for PTSD symptoms. Most family surrogates (228 participants [75.2%]) experienced cooccurring PGD, PTSD, and depressive symptom trajectories, but multiple patterns were discordant. Symptom trajectories cooccurred in joint patterns: resilient (247 participants [81.5%]), recovered (43 participants [14.1%]), and distressed (14 participants [4.5%]). These patterns were characterized by high conditional probabilities for the resilience (PGD, 0.999; PTSD, 0.999; depressive, 0.804), recovery (PGD, 0.854; PTSD, 0.890; depressive, 0.588), and chronic (PGD, 0.921; PTSD, 0.789; depressive, 0.980) symptom trajectories.Conclusions and relevanceIn this cohort study, grief-related psychological symptoms evolved in complex ways during ICU bereavement, as characterized by heterogeneous trajectories. Some ICU bereaved surrogates experienced persistent elevated PGD, PTSD, and depressive symptoms individually or conjointly, underscoring the importance of early screening to identify this population at high risk of comorbid psychological distress trajectories.

Project description:BackgroundBereaved people experience distinct trajectories of prolonged-grief-disorder (PGD) symptoms. A few studies from outside critical care investigated limited factors of PGD-symptom trajectories without a theoretical framework. We aimed to characterize factors associated with ICU bereaved surrogates' PGD-symptom trajectories, drawing from the integrative framework of predictors for bereavement outcomes, emphasizing factors modifiable by ICU care.MethodsProspective cohort study of 291 family surrogates. Multinomial logistic regression was used to determine associations of three previously identified PGD-symptom trajectories (resilient [n = 242, 83.2%] as reference group, recovery [n = 35, 12.0%], and chronic [n = 14, 4.8%]) with risk factors. Factors included intrapersonal (demographics, personal vulnerabilities), interpersonal (perceived social support), bereavement-related (patient demographics, clinical characteristics, and patient-surrogate relationship), and death-circumstance (surrogate-perceived quality of patient dying and death [QODD] in ICUs classified as high, moderate, poor-to-uncertain, and worst QODD classes) factors.ResultsMost surrogates were female (59.1%), the patient's adult child (54.0%), and about (standard deviation) 49.63 (12.53) years old. As surrogate age increased, recovery-trajectory membership decreased (adjusted odds ratio [95% confidence interval] = 0.918 [0.849, 0.993]) and chronic-trajectory membership increased (1.230 [1.010, 1.498]). Being married decreased membership in the recovery (0.186 [0.047, 0.729]) trajectory. Higher anxiety symptoms 1 month post loss increased membership in recovery (1.520 [1.256, 1.840]) and chronic (2.022 [1.444, 2.831]) trajectories. Spouses were more likely and adult-child surrogates were less likely than other relationships to be in the two more profound PGD-symptom trajectories. Membership in the chronic trajectory decreased (0.779 [0.614, 0.988]) as patient age increased. The poor-to-uncertain QODD class was associated with a nearly significant increase (4.342 [0.980, 19.248]) in membership in the recovery trajectory compared to the high QODD class.ConclusionsMembership in the PGD-symptom trajectories was associated with factors modifiable by high-quality ICU care, including anxiety symptoms at early bereavement and surrogate-perceived QODD in the ICU. Clinicians should be sensitive to the psychological needs of at-risk family surrogates, provide high-quality end-of-life care to facilitate QODD, and promptly refer bereaved surrogates who suffer anxiety symptoms and profound and/or persistent PGD-symptoms for psychological support.

Project description:IntroductionBereaved parents, who have lost a child, have an elevated risk to develop mental health problems, yet, few studies have evaluated the effect of psychosocial interventions developed for bereaved parents. Cognitive-behavioural therapy (CBT), both face to face or digitally delivered, has shown to be an effective intervention for prolonged grief symptoms. Self-help mobile apps offer various advantages and studies show improved mental health after app interventions. No app has yet been evaluated targeting prolonged grief in bereaved parents. Therefore, the aim of this planned study is to develop and examine the effectiveness of a CBT-based mobile app, called My Grief, in reducing symptoms of prolonged grief, as well as other psychological symptoms, in bereaved parents. Another aim is to assess users' experiences and adverse events of My Grief.Methods and analysisWe will conduct a two-armed randomised waitlist-controlled trial. Parents living in Sweden, who lost a child between one and ten years ago, with elevated symptoms of prolonged grief, will be recruited to participate in the trial. The content of My Grief covers four main domains (Learn; Self-monitoring; Exercises; Get support) and builds on principles of CBT and the proven-effective PTSD Coach app. Participants in the intervention group will fill out online questionnaires at baseline and at 3, 6 and 12 months follow-ups, and the waitlist-controls at baseline and at 3 months. The primary outcome will be prolonged grief symptoms at the 3 months follow-up. Secondary outcomes are post-traumatic stress and depression symptoms, quality of life and cognitive behavioural variables (ie, avoidance, rumination, negative cognitions).Ethics and disseminationEthical approval has been received from the Swedish Ethical Review Authority (project no. 2021-00770). If the app is shown to be effective, the app will be made publicly accessible on app stores, so that it can benefit other bereaved parents.Trial registration numberNCT04552717.

Project description:Background: In China, mental health services do not currently meet the needs of bereaved people with symptoms of prolonged grief disorder (PGD). Internet-based grief interventions may help fill this gap, but such programmes have not yet been developed or evaluated in China. The proposed study aims to investigate the effectiveness, acceptability, and feasibility of an online self-help intervention programme named Healing Grief for bereaved Chinese with prolonged grief, and to explore the psychological mechanisms of potential improvements.Methods: We designed a two-arm randomised controlled trial. At least 128 participants will be randomly assigned to either an Internet-based intervention group or a waitlist-control group. The Internet-based intervention will be developed based on the dual process model, integrating techniques of psychoeducation, behavioural activation, cognitive reappraisal, and meaning reconstruction, and will be delivered via expressive writing. The intervention comprises six modules, with two sessions in each module, and requires participants to complete two sessions per week and complete the intervention in 6 weeks. The primary outcomes include effectiveness, acceptability, and feasibility. The effectiveness will be assessed by measures of prolonged grief, posttraumatic stress, anxiety, and depressive symptoms. Acceptability and feasibility will be evaluated using survey and interview on user experience characteristics. Secondary outcomes include moderators and mediators, such as dual process coping, grief rumination, mindfulness, and continuing bond, to explore the psychological mechanisms of potential improvement. Assessments will take place at pre-intervention, post-intervention, and 3-month follow-up.Conclusion: The proposed study will determine the effectiveness, acceptability, and feasibility of the newly developed online self-help intervention for bereaved Chinese with prolonged grief and clarify how the intervention helps with symptom improvements. Such an intervention may play an important role in easing the imbalance between the delivery and receipt of bereavement psychological services in China.

Project description:Background: Grief is a multi-faceted experience including emotional, social, and physical reactions. Research in ICD-11 prolonged grief disorder (PGD) in different cultural contexts has revealed different or potentially missing grief symptoms that may be relevant.Objective: This study thus aimed to explore the prevalence of somatic symptom distress and its associations with grief and negative affect in a culturally diverse sample of bereaved individuals with symptoms of PGD.Methods: Based on cross-sectional survey data from the Measurement and Assessment of Grief (MAGIC) project, this study included 1337 participants (mean age 23.79 yrs, 76.1% female) from three regions (USA: 62.3%, Turkey/Iran: 24.2%, Cyprus/Greece: 13.5%), who experienced a loss of a significant other. Associations between somatic symptom distress (Somatic Symptom Scale, SSS-8), symptoms of PGD (International Prolonged Grief Disorder Scale, IPGDS-33), anxiety (Generalized Anxiety Disorder Questionnaire, GAD-7), depression (Patient Health Questionnaire, PHQ-9) as well as demographic and loss related characteristics were investigated. Three hundred and thirteen participants (23.4%) scored above the proposed cut-off for clinically severe PGD.Results: 'High' or 'very high' levels of somatic symptom distress were more frequent in a possible PGD group (58.2%), than in a non-PGD group (22.4%), p < .001, as divided per cut-off in the IPGDS. In a multiple regression analysis, PGD symptoms were significantly but weakly associated with somatic symptom distress (β = 0.08, p < .001) beyond demographics, loss-related variables, and negative affect. Negative affect (anxiety and depression) mediated the relationship of PGD symptoms with somatic symptom distress and the indirect effect explained 58% of the variance.Conclusions: High levels of somatic symptom distress can be observed in a substantial proportion of bereaved across cultures. Our findings suggest that PGD is related to somatic symptom distress partly and indirectly through facets of negative affect.

Project description:BackgroundLosing a loved one, through death or separation, counts among the most stressful life events and is detrimental to health and well-being. About 15% of people show clinically significant difficulties coping with such an event. Web-based interventions (WBIs) are effective for a variety of mental health disorders, including prolonged grief. However, no validated WBI is available in French for treating prolonged grief symptoms.ObjectiveThis study aimed to compare the efficacy and adherence rates of 2 WBIs for prolonged grief symptoms following the loss of a loved one through death or romantic separation.MethodsLIVIA 2.0 was developed relying on theoretical and empirical findings on bereavement processes and WBIs, and is compared with LIVIA 1, which has already demonstrated its efficacy. We conducted a randomized controlled trial and provided on-demand guidance to participants. Outcomes were assessed through web-based questionnaires before the intervention, after the intervention (12 weeks later), and at follow-up (24 weeks later). Primary outcomes were grief symptoms, depressive symptoms, and well-being. Secondary outcomes were anxiety symptoms, grief coping strategies, aspects related to self-identity, and program satisfaction.ResultsIn total, 62 participants were randomized (intent-to-treat [ITT] sample), 29 (47%) in LIVIA 2.0 (active arm) and 33 (53%) in LIVIA 1 (control arm). The dropout rate was 40% (37/62), and 10 participants were removed due to exclusion criteria, leading to a final per-protocol sample of 27 (44%) completers who differed from noncompleters only based on reporting fewer anxiety symptoms (t60=3.03; P=.004). Participants who are separated reported more grief symptoms (t60=2.22; P=.03) and attachment anxiety (t60=2.26; P=.03), compared to participants who are bereaved. There were pre-post within-group differences for both programs in the ITT sample, with significant reductions in grief (Cohen d=-0.90), depressive symptoms (Cohen d=-0.31), and centrality of the loss (Cohen d=-0.45). The same pattern was observed in the per-protocol sample, with the exception that anxiety symptoms also significantly diminished (Cohen d=-0.45). No difference was found in efficacy between the 2 programs (all P>.33). Participants (ITT sample) reported overall high levels of program satisfaction (mean 3.18, SD 0.54; over a maximum of 4). Effect stability was confirmed at the 6-month follow-up for all outcomes, with an improvement in self-concept clarity.ConclusionsThe 2 grief-related WBIs were effective in reducing grief, depressive and anxiety symptoms for participants who are bereaved or separated. The analyses did not reveal any pre-post between-group differences, suggesting that the innovations brought to LIVIA 2.0 did not significantly affect the outcome. However, caution is warranted with the interpretation of the results given the limited power of the sample, which only allows the detection of medium effect sizes.Trial registrationClinicalTrials.gov NCT05219760; https://clinicaltrials.gov/study/NCT05219760.International registered report identifier (irrid)RR2-10.2196/39026.
