RELIABILITY AND VALIDITY OF THE DUTCH VERSION OF THE INVENTORY OF TRAUMATIC GRIEF (ITG)

The psychometric properties of the Dutch version of the Inventory of Traumatic Grief (ITG) were investigated in two studies with bereaved adults who had suffered the loss of a first-degree relative. In Study 1, exploratory factor analysis indicated that the items of the ITG clustered together into one underlying factor. In addition, the internal consistency of the ITG and its short-term temporal stability were found to be high. In Study 2 it was found that the ITG exhibited adequate discriminative, concurrent, and construct validity. Furthermore, an ITG cutoff score for a diagnosis of traumatic grief was determined, with a sensitivity of 86% and a specificity of 76%, providing evidence in favor of the predictive validity of the ITG.

Couples at Risk Following the Death of Their Child: Predictors of Grief Versus Depression

This longitudinal study examined the relative impact of major variables for predicting adjustment (in terms of both grief and depression) among bereaved parents following the death of their child. Couples (N = 219) participated 6, 13, and 20 months postloss. Use of multilevel regression analyses enabled assessment of the impact of several predictors and facilitated analysis of factors that were either shared by parents or individual. Grief was predicted mainly by shared parent factors: childs age, cause and unexpectedness of death, and number of remaining children. By contrast, depression was predicted by individual parent factors: gender, religious affiliation, and professional help seeking. Theoretical implications of these findings are discussed.

Initial Validation of the SLEEP-50 Questionnaire

Initial psychometric properties of the SLEEP-50 questionnaire, designed to detect sleep disorders as listed in the Diagnostic and Statistical Manual of Mental Disorders (4th ed., Text Revision), were examined. The sample consisted of 377 college students, 246 sleep patients, 32 nightmare sufferers, and 44 healthy volunteers. The internal consistency was high (Cronbachs alpha = .85); test–retest correlations fell between .65 and .89. Principal component analysis with a direct oblimin rotation revealed a factor structure that closely matched the designed structure. Sensitivity and specificity scores were promising for all sleep disorders; the agreement between all clinical diagnoses and SLEEP-50-classifications was substantial (kappa = .77). These initial findings indicate that the SLEEP-50 seems able to detect a variety of sleep disorders. The SLEEP-50 can aid in screening for common sleep disorders in the general population.

Lucid Dreaming Treatment for Nightmares: A Pilot Study

Background: The goal of this pilot study was to evaluate the effects of the cognitive-restructuring technique ‘lucid dreaming treatment’ (LDT) on chronic nightmares. Becoming lucid (realizing that one is dreaming) during a nightmare allows one to alter the nightmare storyline during the nightmare itself. Methods: After having filled out a sleep and a posttraumatic stress disorder questionnaire, 23 nightmare sufferers were randomly divided into 3 groups; 8 participants received one 2-hour individual LDT session, 8 participants received one 2-hour group LDT session, and 7 participants were placed on the waiting list. LDT consisted of exposure, mastery, and lucidity exercises. Participants filled out the same questionnaires 12 weeks after the intervention (follow-up). Results: At follow-up the nightmare frequency of both treatment groups had decreased. There were no significant changes in sleep quality and posttraumatic stress disorder symptom severity. Lucidity was not necessary for a reduction in nightmare frequency. Conclusions: LDT seems effective in reducing nightmare frequency, although the primary therapeutic component (i.e. exposure, mastery, or lucidity) remains unclear.

Patterns of Attachment and Parents' Adjustment to the Death of Their Child

The impact of adult attachment on psychological adjustment among bereaved parents and the mediating effect of relationship satisfaction were examined among a sample of 219 couples of parents. Data collection took place 6, 13, and 20 months after loss. Use of the actor partner interdependence model in multilevel regression analysis enabled exploration of both individual as well as partner attachment as predictors of grief and depression. Results indicated that the more insecurely attached parents were (on both avoidance and anxiety attachment), the higher the symptoms of grief and depression. Neither the attachment pattern of the partner nor similarity of attachment within the couple had any influence on psychological adjustment of the parent. Marital satisfaction partially mediated the association of anxious attachment with symptomatology. Contrary to previous research findings, avoidant attachment was associated with high grief intensity. These findings challenge the notion that the avoidantly attached are resilient.

Ruminative coping as avoidance: a reinterpretation of its function in adjustment to bereavement

The paper argues for a reconceptualization of ruminative coping with the death of a loved one as an avoidant rather than a confrontational strategy. Ruminative coping has been characterized within the bereavement field as persistent, repetitive and passive focus on negative emotions and symptoms. It has been theoretically described and empirically shown to be a maladaptive process, being conceptually related to complicated/chronic/prolonged grief. Furthermore, it has been contrasted with denial and suppression processes—which, too, have been understood to be maladaptive and associated with major complications following bereavement. Here evidence is reviewed and the case made that rumination is not an opposite form of coping from suppression or denial, but that it is a similar phenomenon to these, and different from the types of confrontation that take place in so-called “grief work”. Implications with respect to intervention for complicated grief are discussed.

Complicated grief and uncomplicated grief are distinguishable constructs.

With data from 242 mourners who received help post-loss and were at least 6 months removed from their loss, it was found that symptoms proposed as denoting complicated grief (CG) are distinguishable from reactions representing uncomplicated grief (UG). With data from a subgroup of 130 mourners, CG but not UG was found to relate to concurrent distress and disability.

Prolonged Grief Disorder, depression, and posttraumatic stress disorder are distinguishable syndromes.

BACKGROUND This study examined the distinctiveness of symptoms of Prolonged Grief Disorder (PGD), depression, and posttraumatic stress disorder (PTSD). We compared the fit of a one-factor model with the fit of four hierarchical models in which symptoms formed three distinct correlated higher-order dimensions, and PTSD-items were modeled in different ways. METHODS Self-reported data were available from two samples; 572 mourners recruited via the internet and 408 mourners recruited via healthcare workers. RESULTS In Sample 1, the unitary model did not fit the data. The four hierarchical models all fit better. The model in which PTSD-items constituted four lower-order factors of reexperiencing, avoidance, dysphoria, and hyperarousal fit the data best. The fit was further improved, when one weak PGD-item and one weak PTSD-item were removed, and error-terms of similar items were allowed to correlate. Findings from Sample 1 were replicated in Sample 2. LIMITATIONS This study relied on self-reported data. Not all PGD-criteria and depression-criteria were assessed. CONCLUSIONS This is the first confirmatory factor analysis study showing that symptoms of PGD, depression, and PTSD represent distinguishable syndromes. PGD-symptoms should be addressed in the assessment and treatment of bereaved people seeking treatment.

Risk Factors for Bereavement Outcome: A Multivariate Approach

Bereavement increases the risk of ill health, but only a minority of bereaved suffers lasting health impairment. Because only this group is likely to profit from bereavement intervention, early identification is important. Previous research is limited, because of cross sectional designs, small numbers of risk factors, and use of a single measure of bereavement outcome. Our longitudinal study avoids these pitfalls by examining the impact of a large set of potential risk factors on grief, depressive symptoms, emotional loneliness, and positive mood following recent bereavement (3 years maximum). Participants provided information 3 times over 6 months. A multivariate approach was chosen to avoid reporting spurious results due to confounding. As expected, risk factors were differentially related to different outcome measures. For example, being high in anxious attachment and having lost a partner were related to more intense feelings of emotional loneliness, whereas these variables did not predict any of the other outcome variables. By contrast, social support did not influence emotional loneliness but did predict grief, depressive symptoms and positive mood. Implications of these findings are discussed.

The role of cognitive variables in psychological functioning after the death of a first degree relative.

The present study sought to explore the relationship between negative cognitions and emotional problems after bereavement, with a group of 329 adults who had suffered the loss of a first degree relative. The following cognitions were assessed: global negative beliefs, cognitions about self-blame, negative cognitions about other peoples responses after the loss, and negative cognitions about ones own grief reactions. Results showed that each of these cognitive variables was significantly related to the severity of symptoms of traumatic grief, depression and anxiety, even when background and loss-related variables that were initially found to influence symptom severity, were statistically controlled. When the shared variance between the cognitive variables was controlled, it was found that global negative beliefs about life, the world, and the future, and threatening interpretations of grief reactions each explained a unique proportion of variance in traumatic grief symptom severity. Global negative beliefs about life, the self and the future, and threatening interpretations of grief explained most variance in depression, while negative beliefs about the self and threatening interpretations of grief explained most variance in anxiety. Overall, the findings are in support of cognitive theories of grief, and suggest that effective treatment of problematic grief will need to address negative cognitions.
