Psychological and environmental correlates of HPA axis functioning in parentally bereaved children: preliminary findings

Prevalence of prolonged grief disorder in bereaved children and adolescents: A systematic review

PURPOSE

Prolonged Grief Disorder (PGD) is a condition recently introduced in international classifications of mental disorders. Although PGD is associated with significant distress and impairment that may have developmental consequences, to date, little is known about its prevalence and associated factors in children and adolescents. The present systematic review registered in PROSPERO (CRD42021236026) aimed to: (i) review existing data on the prevalence of PGD in bereaved children and adolescents; and (ii) identify factors associated with PGD in this population.

METHODS

Six electronic databases, grey literature and a manually searched journal identified 1,716 articles with no backward limit to September 2021. Epidemiological studies were included if they reported the prevalence of PGD in bereaved children and adolescents. Study characteristics, diagnostic and assessment tools, population, loss-related characteristics and prevalence of PGD were reviewed.

RESULTS

Five studies met our inclusion criteria. The reported prevalences of PGD ranged from 10.4% to 32%. Female gender, cognitive avoidance, chronic stressors such as economic hardship, exposure to trauma or other losses appear to be associated with more severe symptoms or even a higher risk of PGD. Conversely, data suggest social support may be protective.

CONCLUSION

This first systematic review found a relatively high prevalence of PGD in bereaved children and adolescents. While further large epidemiological studies are needed, this review highlights the importance of evaluating PGD in current clinical practice and suggests that further research into diagnostic and therapeutic approaches targeting this disorder is warranted.

Assessment Tools for Children who Experience Traumatic Loss: A Systematic Review

Children who experience the traumatic (i.e., violent and/or unexpected) death of a loved one are at risk for a range of adverse developmental and mental health problems, including pathological processes of grief. Over the last decades, conceptualizations of maladaptive grief have varied, resulting in a range of assessment tools and no "gold standard" measure to assess symptoms of prolonged grief in children. The current paper is a systematic review of studies that measured grief in children who experienced traumatic loss in order to determine the measures currently used in the literature with children who experience traumatic loss. Searches were conducted according to the preferred reporting items for systematic reviews and meta-analyses in PUBMED, PsycINFO, and OVID and through hand searches of relevant reference lists. Two authors reviewed each study yielded by searches and conducted data extraction on included studies. Studies were included if they were peer-reviewed, included a measure of grief, and consisted of samples of children (age 18 and younger) whereby at least a portion experienced traumatic loss. Thirty-nine studies met inclusion criteria, from which 17 measures were identified. The most commonly used measure was the Inventory of Complicated Grief (n = 10 studies) followed by the Extended Grief Inventory (n = 6). Most studies used different measures and variations of the same measures to assess similar constructs. All but one measure relied on child self-report. More standardization of measurement across studies is needed, along with parent and/or teacher reported measures.

Cognitive reappraisal, emotional expression and mindfulness in adaptation to bereavement: a longitudinal study

BACKGROUND AND OBJECTIVES

Maladaptive emotion regulation strategies increase prolonged grief and depressive symptoms following bereavement. However, less is known about the role of adaptive emotion regulation strategies in adaptation to loss. Therefore, we examined the concurrent and longitudinal associations of three putative adaptive emotion regulation strategies (cognitive reappraisal, emotional expression, and mindfulness) with prolonged grief and depression symptoms.

DESIGN

A two-wave longitudinal survey.

METHODS

A sample of 397 bereaved Dutch adults (89% female, mean age 54 years) completed validated questionnaires to assess trait cognitive reappraisal, emotional expression, mindfulness and prolonged grief and depression symptoms at baseline (T1) and 344 participants completed symptom measures again six months later (T2).

RESULTS

Zero-order correlations demonstrated that mindfulness, cognitive reappraisal and emotional expression relate negatively to T1 and T2 prolonged grief and depression symptoms. In multiple regression analyses, controlling for relevant background variables, all emotion regulation strategies related negatively to T1 prolonged grief and depression symptoms. In multiple regression analyses, controlling for T1 symptoms and background variables, mindfulness predicted lower T2 depression symptoms.

CONCLUSIONS

Adaptive emotion regulation strategies relate negatively to post-loss psychopathology symptoms, yet only mindfulness longitudinally predicts lower depression symptoms. Dispositional mindfulness may be a protective factor in psychological adaptation to bereavement.

Neurobiological mechanisms involved in maternal deprivation-induced behaviours relevant to psychiatric disorders

Parental care is essential for proper development of stress response and emotion-related behaviours. Epidemiological studies show that parental loss in childhood represents a major risk factor for the development of mental disorders throughout the lifespan, including schizophrenia, depression, and anxiety. In most mammalian species, the mother is the main source of care and maternal behaviours regulate several physiological systems. Maternal deprivation (DEP) for 24 h is a paradigm widely used to disinhibit the hypothalamic-pituitary-adrenal axis response to stress during the stress hyporesponsive period. In this mini-review we will highlight the main DEP-induced neurobiological and behavioural outcomes, including alterations on stress-related hormones, neurogenesis, neurotransmitter/neuromodulatory systems and neuroinflammation. These neurobiological changes may be reflected by aberrant behaviours, which are relevant to the study of mental disorders. The evidence indicates that DEP consequences depend on the sex, the age when the DEP takes place and the age when the animals are evaluated, reflecting dynamic plasticity and individual variability. Individual variability and sex differences have a great relevance for the study of biological factors of stress resilience and vulnerability and the DEP paradigm is a suitable model for evaluation of phenotypes of stress- and emotion-related psychopathologies.

Emotion Regulatory Strategies in Complicated Grief: A Systematic Review

Prolonged grief disorder, characterized by severe, persistent, and disabling grief, has recently been included in the International Classification of Diseases-11 (ICD-11). Emotional disturbances are central to such complicated grief responses. Accordingly, emotion regulation is assumed critical in the development, persistence, and treatment of complicated grief. Yet, a comprehensive review on this topic is lacking. We conducted a systematic review (PROSPERO: CRD42017076061) searching PsycInfo, Web of Science, and PubMed to identify quantitative research examining relationships between emotion regulation and complicated grief. Sixty-four studies on 7,715 bereaved people were identified, focusing on a variety of emotion regulation strategies (i.e., experiential avoidance, behavioral avoidance, expressive suppression, rumination, worry, problem solving, cognitive reappraisal, positive thought, and mindfulness). Our synthesis showed strong evidence that experiential avoidance and rumination play a role in the persistence of complicated grief. More generally, surveys support positive associations between putative maladaptive emotion regulation strategies and complicated grief, and negative associations between putative adaptive emotion regulation strategies and complicated grief. Laboratory research yielded mixed results. Emotion regulation is critical in complicated grief, and in particular experiential avoidance and rumination form important targets in complicated grief treatments. We advise expanding current knowledge, by employing more advanced, intensive data collection methods and experiments across diverse samples. Increasing knowledge in this domain will improve clinical practice.

Initial Validation and Measurement Invariance of the Active Inhibition Scale Among Traumatized and Grieving Youth

The Active Inhibition Scale (AIS; Ayers, Sandler, & Twohey, 1998) is an 11-item, self-report measure of emotional suppression among children and adolescents. Previous research with the AIS has linked emotional suppression to several clinically significant outcomes, such as posttraumatic stress symptoms (PTSS) and suicide, among trauma-exposed and bereaved youth; however, there are no published evaluations of its psychometric properties. We examined the factor structure and criterion validity of the AIS in two samples. Sample 1 included youth (M = 12.22 years, SD = 2.96, range: 6-18 years; 55.4% female) referred to an outpatient psychology clinic specializing in childhood trauma and grief. Sample 2 included youth (M = 13.18 years, SD = 2.58, range: 8-18 years; 61.8% female) referred to a community grief counseling center. Confirmatory factor analytic results supported a one-factor solution, Cronbach's α = .94. Additionally, AIS scores correlated positively with PTSS, depression, and maladaptive grief, rs = .43-.64. Evidence of factorial invariance was found across gender, race/ethnicity, and age group. Emotional suppression scores were higher among girls compared to boys, Black and Hispanic youth compared to White youth, and older compared to younger age groups. The magnitude of correlations between AIS and symptom measure scores was comparable across groups. These results support the reliability and criterion validity of the AIS with diverse youth populations and underscore the role that emotional suppression may play in explaining group differences in mental health symptoms.

Complicated Grief and Cortisol Response: An Integrative Review of the Literature

BACKGROUND

The loss of a loved one, especially by a caregiver, can be stressful. Grief can affect one emotionally, mentally, behaviorally, spiritually, and physically and affects individuals differently. Complicated grief (CG), especially for a caregiver, can be intense, prolonged, and interfere with normal activities accompanied by destructive thoughts and behaviors.

AIM

To synthesize the available research on persons experiencing CG and the effect on cortisol levels.

METHODS

A literature search for articles published on CG and cortisol was performed using PubMed, Cochrane Library, PsychINFO, and Web of Science. Search terms included CG, cortisol, and their variants. No date limitations were applied. In accordance with PRISMA, articles were sorted and evaluated against specific inclusion and exclusion criteria.

RESULTS

The search yielded 18 articles, of which 5 were included in the review.

CONCLUSIONS

Cortisol levels and diurnal patterns are shown to be affected in individuals experiencing CG. With prolonged bereavement and dysregulated cortisol, physical and mental health outcomes may result warranting a need for effective stress reduction therapies for this population.

Out of the Mouths of Babes: Links Between Linguistic Structure of Loss Narratives and Psychosocial Functioning in Parentally Bereaved Children

This study examined links between the language bereaved children use to describe the death of their caregiver and children's psychological/behavioral functioning and coping strategies. Participants included 44 children (54.5% male) aged 7 to 12 (M = 9.05) years who were bereaved by the death of a caregiver. Children were assessed via self- and caregiver-report measures and an in-person interview regarding the loss of their caregiver. Children's loss narratives gathered through in-person interviews were transcribed and subjected to textual analysis. Linguistic categories included pronouns and verb tense. Drawing from linguistic and self-distancing theories, we hypothesized that children's use of language reflecting self-distancing (third-person pronouns and past tense) or social connectedness (first-person plural pronouns) would be negatively associated with psychological/behavioral distress and avoidant coping. Similarly, we expected that children's use of self-focused language (first-person singular pronouns and present tense) would be positively associated with psychological/behavioral distress and avoidant coping. As hypothesized, preliminary findings suggest that children who employed more self-distancing language and used more social connectedness words reported less avoidant coping, rs = .40-.42. Also as hypothesized, children who employed more self-focused language had higher levels of self-reported posttraumatic stress symptoms, r = .54, and avoidant coping, r = .54, and higher parent-reported psychological/behavioral distress, r = .43. Implications for theory-building, risk screening, and directions for future research with bereaved youth are discussed.

Caregivers' positive emotional expression and children's psychological functioning after parental loss

The death of a loved one, particularly a parent, has been identified as not only the most common, but also the most distressing form of adversity youth may experience in their lifetime. Surviving caregivers' communication with their children may play a critical role in shaping bereaved children's psychological functioning. However, few studies have examined the specific content (e.g., word usage) of caregivers' verbal communication as a predictor of psychological functioning in bereaved youth. In a sample of 39 parentally-bereaved children and their surviving caregivers, we investigated whether the frequency of caregivers' use of positive emotion words (e.g., "love", "happy", "hope") during a reminiscing task about the deceased was associated with children's psychological functioning and coping. In a cross-sectional analysis, we specifically examined whether these associations were moderated by the amount of time passed since children lost their parents. The Linguistic Inquiry and Word Count Program (LIWC) was used to code and evaluate the percentage of positive emotion words caregivers used during the discussion. When caregivers used more positive emotion words, children were less likely to experience depression, anxiety, and avoidant coping. Those associations were present for children who had experienced parental loss at least 105 days prior to the study. Our findings have implications for how caregivers can support their children and help to alleviate psychological distress in the aftermath of parental loss.

Psychosocial functioning and the cortisol awakening response: Meta-analysis, P-curve analysis, and evaluation of the evidential value in existing studies

Cortisol levels rise immediately after awakening and peak approximately 30-45min thereafter. Psychosocial functioning influences this cortisol awakening response (CAR), but there is considerable heterogeneity in the literature. The current study used p-curve and meta-analysis on 709 findings from 212 studies to test the evidential value and estimate effect sizes of four sets of findings: those associating worse psychosocial functioning with higher or lower cortisol increase relative to the waking period (CARi) and to the output of the waking period (AUCw). All four sets of findings demonstrated evidential value. Psychosocial predictors explained 1%-3.6% of variance in CARi and AUCw responses. Based on these effect sizes, cross-sectional studies assessing CAR would need a minimum sample size of 617-783 to detect true effects with 80% power. Depression was linked to higher AUCw and posttraumatic stress to lower AUCw, whereas inconclusive results were obtained for predictor-specific effects on CARi. Suggestions for future CAR research are discussed.

Emotional Competence and Anxiety in Childhood and Adolescence: A Meta-Analytic Review

Anxiety is conceptualized as a state of negative emotional arousal that is accompanied by concern about future threat. The purpose of this meta-analytic review was to evaluate the evidence of associations between emotional competence and anxiety by examining how specific emotional competence domains (emotion recognition, emotion expression, emotion awareness, emotion understanding, acceptance of emotion, emotional self-efficacy, sympathetic/empathic responses to others' emotions, recognition of how emotion communication and self-presentation affect relationships, and emotion regulatory processes) relate to anxiety in childhood and adolescence. A total of 185 studies were included in a series of meta-analyses (N's ranged from 573 to 25,711). Results showed that anxious youth are less effective at expressing (r = -0.15) and understanding emotions (r = -0.20), less aware of (r = -0.28) and less accepting of their own emotions (r = -0.49), and report less emotional self-efficacy (r = -0.36). More anxious children use more support-seeking coping strategies (r = 0.07) and are more likely to use less adaptive coping strategies including avoidant coping (r = 0.18), externalizing (r = 0.18), and maladaptive cognitive coping (r = 0.34). Emotion acceptance and awareness, emotional self-efficacy, and maladaptive cognitive coping yielded the largest effect sizes. Some effects varied with children's age. The findings inform intervention and treatment programs of anxiety in youth and identify several areas for future research.

Supporting youth grieving the dying or death of a sibling or parent: considerations for parents, professionals, and communities

PURPOSE OF REVIEW

The aim of this article is to highlight considerations for parents, professionals, and communities regarding supporting children and adolescents who are grieving the dying or death of a parent or sibling.

RECENT FINDINGS

Current research is directly engaging the voices of youth who have experienced a parent or sibling's death. Although there continues to be much evidence about the distressing effect of such deaths on children and adolescents, there is a welcome emerging tendency to distinguish between adaptive and maladaptive grief. Although the literature strongly encourages parents to take an open and honest approach to supporting youth prior to a death, many barriers remain to them doing so. The literature identifies healthcare providers as being ideally positioned to provide guidance to families around best practice in the area of preparing youth for the death of a parent or sibling. Following a death, there is now encouraging evidence regarding the efficacy of certain interventions for bereaved youth, both in the short and long term, which is an important development in the field.

SUMMARY

Youth benefit from being involved in open and honest conversations about a family member's cancer diagnosis, treatment, prognosis, and end-of-life care. Although advances are being made with regard to understanding the grief experience of youth, there remains a wide gap between the current theoretical knowledge and the availability of practical well informed support for grieving youth.

Differential associations between childhood trauma subtypes and adolescent HPA-axis functioning

Studies examining the association between childhood trauma exposure and neuroendocrine functioning have returned inconsistent findings. To date, few studies have accounted for the role exposure to different types of childhood trauma may have on different neuroendocrine adaptations, and no study has examined this association using multiple indices of hypothalamic-pituitary-adrenal axis (HPA-axis) functioning. The purpose of this study was to characterize the unique associations between exposure to physical abuse, emotional abuse, and non-intentional trauma, and multiple indices of HPA-axis functioning.

METHODS

A community sample of 138 youth (aged 9-16) completed the Socially Evaluated Cold Pressor Task (SE-CPT) while their parents completed the Early Trauma Inventory (ETI). All youth then collected 4 diurnal salivary cortisol samples at home across 2 consecutive weekdays.

RESULTS

High reported exposure to non-intentional trauma was associated with intact diurnal regulation but elevated cortisol at bedtime, physical abuse was associated with faster reactivity to acute stress, and emotional abuse was associated with delayed recovery of cortisol following acute stress. Taken together, there was a heterogeneous relationship among different indices of HPA-axis functioning and trauma subtype.

DISCUSSION

Different types of childhood trauma exposure are related to distinct anomalies in HPA-axis functioning. This study underscores the importance of research incorporating multiple indices of HPA-axis functioning to inform our understanding of the underlying neuroendocrine dysregulation that may later lead to stress-related psychopathology.
