Korean Version of Inventory of Complicated Grief Scale: Psychometric Properties in Korean Adolescents

Support for Complicated Grief in Military Primary Care: Associations, Challenges, and Opportunities

OBJECTIVE

This study examined whether service members and their families engage in communication with their primary care managers (PCMs) regarding their losses and to what extent PCMs provide counseling or referrals for grief-related concerns. Additionally, the study explored the potential associations between ethnicity, age, military status (dependent, service member, or veteran), gender, patients' disclosure of loss to their PCM, receipt of referrals for grief-related services, and treatment seeking.

METHODS

A survey was administered to 161 patients enrolled in primary care at William Beaumont Army Medical Center, with 138 reporting a significant loss. Bereaved respondents completed the Inventory of Complicated Grief and the Prolonged Grief Disorder-13 Revised scale (PG-13). Respondents were also asked questions related to their loss and their interactions with their PCM related to the loss.

RESULTS

One hundred twenty-five bereaved respondents completed the measures, 13 had missing information related to PCM interactions. Twenty-nine percent (n = 36) of the 112 respondents reported a significant loss to their PCM. These respondents exhibited significantly higher symptom severity, as indicated by their total mean scores on the Inventory of Complicated Grief and the PG13. Seventeen percent (n = 6) of these respondents reported receiving counseling on topics related to grief or a referral for grief care from their PCM. A moderate relationship was identified between military status and communication with PCM, such that current service members were least likely to report, followed by veterans, then dependents. A moderate relationship was also found between ethnicity and treatment seeking.

CONCLUSION

The study's findings have implications for primary care and highlight opportunities for improved outcomes, including the development of appropriate assessment protocols, interventions, and educational initiatives to address grief-related concerns within the military healthcare system. Future research should further investigate the specific needs and preferences of military personnel and their families to enhance the delivery of targeted and effective healthcare services.

Prevalence and Correlates of Complicated Grief in Military Primary Care: Implications for Healthcare Providers

Grief is a universal experience, but for approximately 1 in 10 individuals, grief can become impairing. Despite servicemembers' frequent exposure to death, research on grief in the military remains limited. The purpose of the study was to explore the prevalence and correlates of complicated grief (CG) in military primary care. A quantitative survey was conducted with 161 non-treatment-seeking service members, veterans, and their dependents, of whom 138 reported a significant loss. Results revealed that 35% of the respondents who were bereaved met the cut-off score of 25 on the Inventory of Complicated Grief (ICG). Furthermore, 10% met the cut-off score of 30 on the Prolonged Grief Disorder-13-Revised Scale (PG-13-R). Importantly, death by suicide and pre-existing mental health conditions were associated with greater symptom severity. These findings have important implications for primary care providers and other clinicians working with military populations.

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.

The Relationship Between Childhood Trauma Experience and Complicated Grief: The Importance of Psychological Support for Individuals Coping With Pet Loss in Korea

BACKGROUND

Loss of companion animals can result in various psychological reactions, including complicated grief, depression, anxiety, and insomnia. However, research on the prevalence of patients requiring clinical intervention is limited. Moreover, research examining the relationship between childhood trauma and psychological symptoms after pet loss is lacking. Therefore, this study aimed to investigate the rates of clinically significant psychological distress after pet loss and the impact of childhood trauma on adults who have experienced pet loss.

METHODS

An online survey was conducted with non-clinical adult participants who had experienced the loss of a companion animal. Psychiatric characteristics were evaluated using standardized assessments, including the Inventory of Complicated Grief (ICG), the Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder-7 (GAD-7), and the Insomnia Severity Index (ISI). Childhood trauma was evaluated using the Childhood Trauma Questionnaire (CTQ).

RESULTS

In a sample of 137 individuals who had experienced pet loss, the percentages of those who exceeded the cutoff points were 55% for the ICG, 52% for the PHQ-9, 40% for the GAD-7, and 32% for the ISI. The group that reported childhood trauma exhibited significantly higher scores on the ICG (t = 2.16, P = 0.032), PHQ-9 (t = 3.05, P = 0.003), GAD-7 (t = 2.61, P = 0.010), and ISI (t = 2.11, P = 0.037) than in the group without childhood trauma. For participants who experienced pet loss for less than one year, there was no significant difference in the ICG between the trauma and non-trauma groups, as both had extremely high scores. However, the trauma group had a significantly higher PHQ-9 (t = 2.58, P = 0.012) than the non-trauma group. In contrast, for participants who experienced pet loss for more than one year, the trauma group had a significantly higher ICG (t = 2.22, P = 0.03) than the non-trauma group, while there was no significant difference in the PHQ-9. Additionally, the emotional abuse scores on the CTQ were most significantly correlated with the ICG scores even after controlling for depressive symptoms.

CONCLUSION

People who experienced pet loss had significant psychological symptoms, ranging from 32% to 55%. Childhood trauma experiences affect complicated grief, depressive symptoms, anxiety symptoms, insomnia and prolonged grief disorder after pet loss. After pet loss, people with childhood trauma may require more psychological help than those without trauma.

Bereavement issues and prolonged grief disorder: A global perspective

The death of a loved one - bereavement - is a universal experience that marks the human mental health condition. Grief - the cognitive, emotional, and behavioral responses to bereavement - is thus experienced by virtually everyone at some point in life, while mourning is a process through which grievers come to terms with the loss envisioning life without the deceased. Although distress subsides over time among most bereaved individuals, a minority will develop a condition recently identified as prolonged grief disorder (PGD). The present review provides a global perspective on bereavement, grief reactions, and PGD. Although the loss of a loved one and grief reactions are in general experienced consistently across different cultures, differences and variations in their expression may exist across cultures. Especially within specific populations that may be more at risk for PGD, possibly due to risk factors associated with the mechanisms of loss (e.g., refugees, migrants, and conflict survivors). The diagnostic criteria for PGD are mostly based on Western grieving populations, and cultural adaptations of PGD treatments are limited. Therefore, cross-cultural development and validation of PGD screening/assessment is critical to support future research on grief reactions and PGD, especially in non-Western contexts, and concerning the potential future global changes and challenges that appear to have a major impact on PGD. More transcultural research on PGD is needed to contextualize and will lead to culture-bound symptom identification of PGD, and the adaptation of current treatment protocols, which may ultimately improve health at the individual level, and health-care systems.

Grief Instruments in Children and Adolescents: A Systematic Review

Many children and adolescents experience the death of a close person, such as a family member or a friend. However, there is a scarcity of literature on the assessment of grief in bereaved youth. The use of validated instruments is essential to advance our knowledge of grief in children and adolescents. We conducted a systematic review, adhering to PRISMA guidelines, to identify instruments that measure grief in this population and explore their characteristics. Searches in six databases (Medline, PsycINFO, Embase, Emcare, Scopus, and Web of Science) identified 24 instruments, encompassing three categories: general-purpose grief scales, maladaptive grief scales, and specialized grief scales. We extracted data using a predetermined list of descriptive and psychometric properties. Findings indicate a need to direct research towards more stringent validation of existing instruments and the design of new instruments in line with developments in the understanding of grief in this population.

The Inventory of Complicated Grief-A Systematic Psychometric Review and Conceptual Replication Study of the Structural Validity

The Inventory of Complicated Grief (ICG) is a commonly used self-report measure in psycho-oncology, best supportive care, and palliative medicine. However, existing validation studies yielded conflicting results regarding the structural validity. This study provides a psychometric review and conceptual replication of the ICG latent structure to test the hypothesis that existing studies overfit unreliable sources of variance, which overshadow the unidimensionality of the ICG. All proposed latent models identified in the psychometric review were tested in a series of confirmatory and exploratory structural equation models. Specifically, at least five to six latent intercorrelated factors were necessary to reach acceptable model fit. However, a general CG factor accounted for most variance and ICG sum scores showed predictable associations with anxiety and depressive symptoms, which suggests that the ICG is essentially unidimensional. There are indications that other measures of pathological grief show similar inconsistencies. Overall, potentially emerging subfacets of the ICG should not be interpreted as distinct "symptom clusters." If time constraints are an issue as is often the case in clinical research, complicated grief may just be measured by a reduced item set without a significant loss of information or complexity.

Psychometric Properties of the Persian Version of the Inventory of Complicated Grief

The aim of this study was to investigate the psychometric properties of the Persian version of the Inventory Complicated Grief (ICG) including reliability, validity and factorial structure. In this cross-sectional study, 332 women and men bereaved at least 6 months from the adult population of Iran. The results showed Cronbach's alpha was found to be 0.94 for the scales overall score. Inventory Complicated Grief found a positive and significant correlation between the beck depression inventory (BDI) (r = .62, p < .001) and grief experience questionnaire (r = .74, p < .001). Still, he also found that there was a negative correlation between adult hope scale (r = -.44, p < .001). Furthermore, the results of the EFA result showed four factors on this scale. Overall, ICG showed good reliability and validity in Iranian population and it could be applied for assessing their Complicated Grief.

Validation of the Lifetime Incidence of Traumatic Events (LITE-S/P) Questionnaires in Children and Adolescents in Slovenia

Introduction: A traumatic event is an extremely threatening and frightening experience in an individual's life. Children who are exposed to traumatic events are twice as likely to develop a mental disorder. Screening can provide insight into the traumatic experience of children, identifying those eligible for further evaluation, and support. With this aim, we evaluated the psychometric properties of the Lifetime Incidence of Traumatic Events questionnaire (LITE) in Slovene by calculating retest reliabilty, construct validity (cross-informant agreement) and external validity, where we calculated the correlation of the number of differenet traumatic events with psychopathological symptoms. Methods: 280 child-parent pairs (children aged 11.3 ± 2.2 years) from various Slovenian primary schools participated in the study. They were divided into two groups: 180 healthy primary school students and 100 children with Type 1 Diabetes (our study was a part of a larger study The Influence of Psychobiological Adversity on Children and Adolescents with Type 1 Diabetes Study). Two versions of the LITE questionnaire were used. Children completed the child report (LITE-S) and parents the parent report (LITE-P) version. After 4 weeks, 117 children, and 114 parents filled out the LITEs again. External validity was assessed using the Youth Self Report and Child Behaviour Checklist syndrome-oriented scales. Results: Retest reliability for individual scales was r = 0.469-0.639 (ρ = 0.443-0.636; p < 0.001), but higher for individual items (κ = 0.263-0.821; p < 0.001). Correlations between reports from parents and children were r = 0.313-0.345 (ρ = 0.317-0.348; p < 0.001). The number of different events experienced by children correlated significantly with the measured depressive-anxiety, and posttraumatic stress disorder symptoms. Conclusions: Based on our results, the LITE-S and LITE-P "All events" scale have acceptable psychometric properties for use in research and in clinical practise screening. We recommend looking at single items, taking into consideration the responses from both the child and the parent for more precise information. To improve the precision of the psychodiagnostic capacity of the questionnaire, further research on various populations should be performed.

Attachment Style, Complicated Grief and Post-Traumatic Growth in Traumatic Loss: The Role of Intrusive and Deliberate Rumination

OBJECTIVE

The present study examines the effects of attachment styles on the grief response and the indirect effect of rumination in parents who lost a child in the Sewol Ferry accident.

METHODS

Bereaved parents (n=81) completed self-report questionnaires evaluating their attachment style (Experience in Close Relationship-Short form), traumatic loss related rumination (Event-Related Rumination Inventory), degree of complicated grief (Inventory of Complicated Grief), and post-traumatic growth (Post-Traumatic Growth Inventory). Data were analyzed using correlation analysis, structural equation modeling, and bootstrapping.

RESULTS

The indirect effect of event-related intrusive rumination was significant in the relationship between attachment avoidance and complicated grief. The path from attachment avoidance to post-traumatic growth via deliberate rumination was not significant. With respect toattachment anxiety and post-traumatic growth, the indirect effect of deliberate rumination was significant. But the indirect effect of intrusive rumination was not significant in the relationships among attachment anxiety, complicated grief, and post-traumatic growth.

CONCLUSION

Individuals with attachment anxiety could obtain post-traumatic growth via deliberate rumination. By contrast, attachment avoidance was associated with the risk of maladaptive grief. Grief interventions should account for individual differences in attachment styles through interventions that manage intrusive rumination and strengthen deliberate rumination.

Inventory of complicated grief: Factor structure among middle-aged and older bereaved parents

This study examines the psychometric properties and factorial structure of the Hebrew version of Prigerson's Inventory of Complicated Grief (ICG), on 116 middle-aged and older Israeli bereaved parents. Analysis revealed a three-factor structure: emotional distress, yearning for the dead and social-emotional detachment. A high percentage of explained variance and sound internal consistency were found for the entire scale and for all factors, as well as adequate convergent and construct validity. These findings suggest that the Hebrew version of the ICG questionnaire is reliable, valid and appropriate for evaluation of grief in later life.

Psychometric Evaluation of the Swedish Version of the Prolonged Grief Disorder-13 (PG-13) in a Bereaved Mixed Trauma Sample

Background: This study aimed to examine the psychometric properties of the Swedish PG-13 in a bereaved trauma exposed sample. A second aim was to examine the latent structure of prolonged grief using the PG-13. Methods: The participants were adults (n = 123) taking part in an ongoing longitudinal study regarding the effects of potentially traumatic events. Participants had experienced a potentially traumatic event in the past 5 years and had reported a death of a significant other either as their primary traumatic event or in addition to another traumatic event. Assessment included self-report of prolonged grief, posttraumatic stress, and general psychological distress. Clinical interviews were used to assess depression, posttraumatic stress disorder, and disability level. The psychometric properties of the Swedish PG-13 were examined through reliability tests and assessment of associations with symptoms of posttraumatic stress, depression, general psychological distress, and disability level. Principal component analysis (PCA) and confirmatory factor analyses (CFA) were used to assess the latent structure. Results: The internal consistency (Cronbach's α = 0.86) and test-retest (r = 0.86) reliability were good. PCA suggested a three-factor model as descriptive of the latent structure of the instrument. Therefore, the CFA used this model, as well as two models suggested in the literature. The three-factor model had the best fit to data. Support of concurrent validity of PG-13 was shown by moderate positive associations with measures of posttraumatic stress, depression, and general psychological distress. Conclusions: The Swedish PG-13 demonstrated good psychometric properties, and its use in research and practice to assess prolonged grief was supported. The factor analyses provided stronger support for models with two or three factors, as compared with a unidimensional model of prolonged grief, with the three-factor model having the best fit.

Posttraumatic Symptoms and Change of Complicated Grief among Bereaved Families of the Sewol Ferry Disaster: One Year Follow-up Study

BACKGROUND

The objective of this study was to determine whether severity and severity change of coexisting psychiatric symptoms might affect change of complicated grief (CG) regarding the Sewol ferry disaster.

METHODS

Data from a cross-sectional survey were obtained 18 months (Time 1) and 30 months (Time 2) after the disaster. We ascertained sociodemographic variables and variables obtained from self-reporting questionnaires (i.e., CG, depression, anxiety, post-traumatic stress disorder [PTSD], insomnia, embitterment, and suicidal risk) among 56 bereaved family members.

RESULTS

Severity of other psychiatric symptoms at Time 1 had no effect on change of CG at Time 2. However, changes in severity of PTSD over a year affected change of CG.

CONCLUSION

It is important to evaluate changes in severity of PTSD and its treatment during management of CG, especially when it involves bereaved families experiencing a traumatic accident.

Frontal Alpha Asymmetry, Heart Rate Variability, and Positive Resources in Bereaved Family Members with Suicidal Ideation after the Sewol Ferry Disaster

OBJECTIVE

After the Sewol ferry disaster, bereavement with suicidal ideation was a critical mental health problem that was accompanied by various neuropsychological symptoms. This study examined the frontal alpha asymmetry (FAA), heart rate variability (HRV), and several psychological symptoms in bereaved family members (BFM) after the Sewol ferry disaster.

METHODS

Eighty-three BFM after the Sewol ferry disaster were recruited. We assessed FAA, HRV, and psychological symptoms, including depression, post-traumatic stress, post-traumatic growth factor, anxiety, grief, and positive resources, between BFM with the presence and absence of current suicidal ideation.

RESULTS

Compared to BFM without suicidal ideation, BFM with suicidal ideation showed a higher FAA with right dominance. Significant differences in psychological symptoms were observed between the groups. In BFM with suicidal ideation, the low: high frequency (LF:HF) ratio correlated with social resources and support.

CONCLUSION

The FAA and LF:HF ratio may be biomarkers that represent the pathological conditions of BFM with suicidal ideation. If researched further, they may shed light on the interaction between bereavement with suicidal ideation and social resources for therapeutic intervention.

Five Months Follow-up Study of School-based Crisis Intervention for Korean High School Students Who Experienced a Peer Suicide

BACKGROUND

The purpose of this study was to examine post-traumatic stress, depression, anxiety, and complicated grief in Korean high school students who experienced a peer suicide.

METHODS

A total of 956 students were included in the statistical analysis. One week after a peer suicide, a school-based crisis intervention program was conducted. The cohort was followed-up at one week and five months after a peer suicide. The program consists of screening tests, educational sessions, and further interview with psychiatric specialists for the selected group. Screening tests were conducted for all students to measure the Child Report of Post-traumatic Symptoms (CROPS), the post-traumatic stress symptoms (The University of California at Los Angeles post-traumatic stress disorder [PTSD] reaction index; UCLA-PTSD-RI), the anxiety symptoms (The Korean-Beck Anxiety Inventory; K-BAI), the depressive symptoms (The Korean-Beck Depression Inventory-II; K-BDI-II), and the complicated grief reaction (The Inventory of Complicated Grief; ICG). For statistical analysis, the SPSS Statistics 21.0 program was used.

RESULTS

At baseline and five months follow-ups, 8.6% and 2.9% of the students showed post-traumatic stress symptoms. At five months follow-up, there was a statistically significant decline in the post-traumatic stress symptoms, anxiety, depression, and complicated grief among the 'trauma group.' A higher proportion of the female students showed post-traumatic stress symptoms after the incident of peer suicide than the male students.

CONCLUSION

School-based crisis intervention helps improvement of trauma-related symptoms. It might be an effective way to prevent suicide spreading among students by alleviating trauma-related symptoms.

Internalizing Symptoms as Mediators of Lifetime Incidence of Trauma and Quality of Life among Out-of-School Youths

Objectives

The present study aimed to investigate the relationships among the lifetime incidence of trauma, internalizing symptoms, and quality of life (QoL) in out-of-school youths (OSYs).

Methods

We recruited 50 OSYs in South Korea. Participants completed the following surveys: completed Lifetime Incidence of Traumatic Events for children, Youth Self Report, and The KIDSCREEN-27 QoL measure for children and adolescents. Mediation analysis was conducted to test the research hypotheses.

Results

The mean lifetime incidence of traumatic events among OSYs was 3.27 (standard deviation, 2.41). Internalizing symptoms significantly mediated the lifetime incidence of trauma and QoL. OSYs with fewer internalizing symptoms exhibited a better QoL in the domain of psychological well-being, although their lifetime incidence of trauma was higher.

Conclusion

The results of current study suggest that assessment and therapeutic intervention with regard to internalizing symptoms are needed to increase the QoL of OSYs.

Increased beta power in the bereaved families of the Sewol ferry disaster: A paradoxical compensatory phenomenon? A two-channel electroencephalography study

AIM

The Sewol ferry capsizing accident on South Korea's southern coast resulted in the death of 304 people, and serious bereavement problems for their families. Electroencephalography (EEG) beta frequency is associated with psychiatric symptoms, such as insomnia. The aim of this study was to investigate the relation between frontal beta power, psychological symptoms, and insomnia in the bereaved families.

METHODS

Eighty-four family members of the Sewol ferry victims (32 men and 52 women) were recruited and their EEG was compared with that of 25 (13 men and 12 women) healthy controls. A two-channel EEG device was used to measure cortical activity in the frontal lobe. Symptom severity of insomnia, post-traumatic stress disorder, complicated grief, and anxiety were evaluated.

RESULTS

The bereaved families showed a higher frontal beta power than healthy controls. Subgroup analysis showed that frontal beta power was lower in the individuals with severe insomnia than in those with normal sleep. There was a significant inverse correlation between frontal beta power and insomnia symptom in the bereaved families.

CONCLUSION

This study suggests that increased beta power, reflecting the psychopathology in the bereaved families of the Sewol ferry disaster, may be a compensatory mechanism that follows complex trauma. Frontal beta power could be a potential marker indicating the severity of sleep disturbances. Our results suggest that sleep disturbance is an important symptom in family members of the Sewol ferry disaster's victims, which may be screened by EEG beta power.

What Factors Impact Consumer Perception of the Effectiveness of Health Information Sites? An Investigation of the Korean National Health Information Portal

Lay public's concerns around health and health information are increasing. In response, governments and government agencies are establishing websites to address such concerns and improve health literacy by providing better access to validated health information. Since 2011, the Korean government has constructed the National Health Information Portal (NHIP) website run in collaboration with the Korean Academy of Medical Sciences (KAMS). This study therefore aimed to 1) examine consumer use of NHIP, with respect to the usage patterns, evaluation on health information provided, and perceived effectiveness of the site; and 2) identify factors that may impact perceived effectiveness of the site. An online survey was conducted with 164 NHIP users, recruited through a popup window on the main screen of the portal website from October to November 2015. The significant predicting factors supported by the data include the relevance of health information on the site, the usefulness of information in making health decisions, and the effective visualization of information. These factors can inform future efforts to design more effective health information websites, possibly based on metadata systems, to further advance the lay public's information seeking and health literacy.
