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

Prolonged Grief Symptoms Predict Social and Emotional Loneliness and Depression Symptoms

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.

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.

Healthcare Workers and Patient Loss During the COVID-19 Pandemic: Interaction Between Grief, Viral Anxiety, and Depression

OBJECTIVE

Coronavirus disease-2019 (COVID-19) had a significant impact on the mental health of healthcare workers. Related assessments should be included in plans for future pandemics. We investigated the connections between grief, viral anxiety, depression, and preoccupation in the context of COVID-19 in healthcare workers, to determine which factors will need to be incorporated.

METHODS

A total of 267 healthcare workers who had experienced the death of at least one patient during the COVID-19 pandemic were asked to respond to questionnaires assessing grief, viral anxiety, depression, loneliness, and preoccupation with COVID-19, based on their emotional state during the 2 weeks immediately after the death. Multivariate linear regression, causal mediation analysis and structural equation modeling were used to examine the psychological processes underlying grief.

RESULTS

Linear regression showed that viral anxiety (β=0.287, 95% confidence interval [CI]: 0.235-0.338, p<0.001) and depression (β= 0.157, 95% CI: 0.073-0.241, p<0.001) had independent associations with preoccupation with COVID-19. Causal mediation analysis revealed that both viral anxiety (proportion mediated: 0.51, 95% CI: 0.37-0.66, p<0.001) and depression (proportion mediated: 0.77, 95% CI: 0.50-1.08, p<0.001) were mediators between grief and preoccupation with COVID-19. In a structural equation model, viral anxiety and depression mediated most of the effects of grief on preoccupation with COVID-19, and loneliness was a mediator between grief and depression.

CONCLUSION

Contingency plans for the next pandemic are being formulated. Effective measures to protect the mental health of healthcare workers should be included, and such measures should consist of assessments for grief, viral anxiety, depression, and loneliness.

The mechanisms of nature-based therapy on depression, anxiety, stress, and life satisfaction: examining mindfulness in a two-wave mediation model

Background

Nature-based therapy (NBT), which centers around engaging in activities within natural surroundings, has consistently demonstrated therapeutic benefits for mental health. While NBT highlights the potential of nature as a therapeutic resource for promoting mental health, there is limited knowledge regarding its underlying mechanisms.

Methods

Two hundred seventy-six Korean participants (204 women, mean age = 54.99 ± 23.25 years) participated in a 30-session gardening program held twice weekly for 15 weeks. Structural equation modeling with a two-wave autoregressive cross-lagged model was used to investigate the mediating effects of mindfulness.

Results

NBT significantly improved the mean scores of all psychological variables. The mediation model was partially confirmed, with mindfulness at post-intervention (T2) mediating the relationship between baseline (T1) depression and anxiety and post-intervention (T2) life satisfaction. However, no significant indirect effect was observed between the path from stress (T1) to life satisfaction (T2).

Conclusion

Mindfulness is a crucial component for improving mental health outcomes. This study underscores the need to prioritize and emphasize mindfulness practices in NBT.

Why Does Grief Hurt?

Abstract. Grief is a major physical and psychological health concern for adults, as well as a key risk factor for depression. The direct and indirect costs of depression in adults place heavy burdens on societal resources. Indeed, bereavement is a stressful and profound life experience, with the grieving process combining reactions to a loss that may originate in complications for bereaved individuals. The goal of this systematic review is to synthesize the findings regarding depression and grief. Studies related to the topic were obtained from multiple databases through rigorous exclusion and inclusion criteria. Only empirical studies with quantitative methodologies were included. Objectives, sample (type of sample, % male, and age), instruments, and main conclusions were extracted from each study. Overall, there are personality and contextual factors that, in addition to affecting depressive reactions following a loss, may also interface with one’s ability to grieve. Furthermore, after the patient’s death, there was a decrease in depressive symptoms over time, indicating that these symptoms are dynamic. Individuals who experience prolonged grief exhibit depressive symptoms, and those who suffer a loss may have depressive symptoms, but in a natural and non-pathological way, that is, sadness and not depression. Depression tends to decrease over time, with the existence of more children and a focus on occupation.

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.

Reciprocal Relations of Worry, Rumination, and Psychopathology Symptoms After Loss: A Prospective Cohort Study

Bereavement can precipitate symptoms of depression, prolonged grief disorder, and posttraumatic stress disorder. Targeting repetitive negative thought (i.e., worry, rumination) in treatment may help reduce post-loss psychopathology. Yet, evidence on longitudinal associations of depressive rumination and worry with post-loss psychopathology symptoms has been mixed and the directions of effects are still unclear. Recently bereaved adults (78% female) completed questionnaires assessing depressive rumination (brooding), worry, and depression, prolonged grief and posttraumatic stress symptoms 11 times in 1.5 month intervals. We applied random-intercept cross-lagged panel models (RICLPMs) to examine reciprocal within-person associations between worry and psychopathology symptoms, between rumination and these symptoms, and between worry and rumination. Main findings were that worry showed reciprocal relationships with psychopathology symptoms (although worry did not consistently predict prolonged grief symptoms). Depressive rumination was predicted by psychopathology symptoms, but not vice versa. Worry showed reciprocal relations with depressive rumination. Findings suggest that worry may be part of a downward spiral, enhancing psychopathology symptoms following loss, whereas depressive rumination is solely a consequence of such symptoms.

Depression, Anxiety and Post-traumatic Growth Among Bereaved Adults: A Latent Class Analysis

Background

The death of a loved one can trigger a range of responses, including painful thoughts and emotions, as well as positive changes, such as post-traumatic growth (PTG). To understand more about the relationship between these outcomes this study explored the co-occurrence of depression, anxiety and PTG among a group of bereaved Chinese adults.

Methods

Data were collected from 194 participants, who had lost a first-degree relative. Latent class analysis was used to analyze the data to identify subgroups of participants with shared symptom profiles.

Results

Three classes were identified: a Growth class, a Depression/Anxiety/Growth class and a Depression/Anxiety class. Marital status, social support, close relationship with the deceased and witnessing the suffering of the deceased were identified as differential predictors of class membership.

Conclusion

The findings contribute to our understanding of the potentially wide ranging impacts of bereavement and highlight the important role of stressor characteristics and support and in influencing impairment and positive outcomes.
