Performance characteristics and clinical utility of diagnostic criteria proposals in bereaved treatment-seeking patients.

BACKGROUND: Persistent complex bereavement disorder (PCBD) is a protracted form of grief included in DSM Section 3 indicating a need for more research. Two other criteria sets [prolonged grief disorder (PGD) and complicated grief (CG) disorder] are also currently in use by researchers. This study evaluates rates of diagnosis of each proposed criteria set in a clinical sample of bereaved individuals participating in clinical research. METHOD: Two groups in which persistent grief was judged to be present or absent completed an assessment instrument that included items needed to diagnose PCBD as well as PGD and CG. One group included grief treatment-seeking participants in our multicenter National Institute of Mental Health (NIMH)-sponsored study who scored ⩾30 on the Inventory of Complicated Grief (ICG) and the other comprised bereaved adults enrolled in clinical research studies who scored <20 on the ICG. Rates of diagnosis were determined for proposed PCBD, PGD and CG criteria. RESULTS: PCBD criteria diagnosed 70 [95% confidence interval (CI) 64.2-75.8] % of the grief treatment-seeking group, PGD criteria identified 59.6 (95% CI 53.4-65.8) % of these individuals and CG criteria identified 99.6 (95% CI 98.8-100.0) %. None of the three proposed criteria identified any cases in the bereaved comparison group. CONCLUSIONS: Both proposed DSM-5 criteria for PCBD and criteria for PGD appear to be too restrictive as they failed to identify substantial numbers of treatment-seeking individuals with clinically significant levels of grief-related distress and impairment. Use of CG criteria or a similar algorithm appears to be warranted.

Does early-onset chronic or recurrent major depression impact outcomes with antidepressant medications? A CO-MED trial report.

BACKGROUND: Prior studies have suggested that major depressive disorder (MDD) with pre-adult onset represents a distinct subtype with greater symptom severity and higher rates of suicidal ideation. Whether these patients have poorer response to various types of antidepressant treatment than those with adult-onset MDD is unclear. Method A total of 665 psychiatric and primary care out-patients (aged 18-75 years) with non-psychotic chronic or recurrent MDD participated in a single-blind, randomized trial that compared the efficacy of escitalopram plus placebo, bupropion sustained-release plus escitalopram, or venlafaxine extended-release plus mirtazapine. We compared participants who self-reported MDD onset (before age 18) to those with a later onset (adult onset) with respect to baseline characteristics and treatment/outcome variables at 12 and 28 weeks. RESULTS: Early-onset chronic/recurrent MDD was associated with a distinct set of sociodemographic (female, younger age) and clinical correlates (longer duration of illness, greater number of prior episodes, greater likelihood of atypical features, higher rates of suicidality and psychiatric co-morbidity, fewer medical problems, poorer quality of life, greater history of child abuse/neglect). However, results from unadjusted and adjusted analyses showed no significant differences in response, remission, tolerability of medications, quality of life, or retention at 12 or 28 weeks. CONCLUSIONS: Although early-onset chronic/recurrent MDD is associated with a more severe clinical picture, it does not seem to be useful for predicting differential treatment response to antidepressant medication. Clinicians should remain alert to an increased risk of suicidality in this population.

Is prior course of illness relevant to acute or longer-term outcomes in depressed out-patients? A STAR*D report.

BACKGROUND: Major depressive disorder (MDD) is commonly chronic and/or recurrent. We aimed to determine whether a chronic and/or recurrent course of MDD is associated with acute and longer-term MDD treatment outcomes. METHOD: This cohort study recruited out-patients aged 18-75 years with non-psychotic MDD from 18 primary and 23 psychiatric care clinics across the USA. Participants were grouped as: chronic (index episode >2 years) and recurrent (n = 398); chronic non-recurrent (n=257); non-chronic recurrent (n=1614); and non-chronic non-recurrent (n = 387). Acute treatment was up to 14 weeks of citalopram (≤ 60 mg/day) with up to 12 months of follow-up treatment. The primary outcomes for this report were remission [16-item Quick Inventory of Depressive Symptomatology - Self-Rated (QIDS-SR(16)) ≤ 5] or response (≥ 50% reduction from baseline in QIDS-SR(16)) and time to first relapse [first QIDS-SR16 by Interactive Voice Response (IVR) ≥ 11]. RESULTS: Most participants (85%) had a chronic and/or recurrent course; 15% had both. Chronic index episode was associated with greater sociodemographic disadvantage. Recurrent course was associated with earlier age of onset and greater family histories of depression and substance abuse. Remission rates were lowest and slowest for those with chronic index episodes. For participants in remission entering follow-up, relapse was most likely for the chronic and recurrent group, and least likely for the non-chronic, non-recurrent group. For participants not in remission when entering follow-up, prior course was unrelated to relapse. CONCLUSIONS: Recurrent MDD is the norm for out-patients, of whom 15% also have a chronic index episode. Chronic and recurrent course of MDD may be useful in predicting acute and long-term MDD treatment outcomes.

Is unrecognized bipolar disorder a frequent contributor to apparent treatment resistant depression?

BACKGROUND: There is widespread clinical belief that unrecognized bipolar disorder (BD) is a frequent contributor to apparent treatment resistant depression (TRD). This review attempts to assess the degree to which prevailing empirical data supports that view. METHODS: All English-language articles published between January 1998 and January 2008 that focused on adults with major depressive disorder (MDD) and BD bearing on the question "Is unrecognized BD a frequent contributor to apparent TRD in patients initially diagnosed with MDD?" were reviewed. RESULTS: 196 articles were reviewed; the preponderance of the data suggested: 1) TRD populations demonstrate high rates of hidden bipolar disorder, 2) there is not sufficient evidence to unequivocally support or reject the hypothesis that patients who relapse despite continued antidepressant treatment are likely to have bipolar spectrum disorder, 3) patients initially diagnosed with MDD do not demonstrate high rates of switching to mania or hypomania when treated with antidepressants and 4) in patients diagnosed with BD, antidepressants are not robustly effective and are poorly tolerated. LIMITATIONS: The main limitation of this review is that none of the individual studies were designed to test our primary hypothesis. CONCLUSIONS: This review provides at least moderate support to the hypothesis that BD is a contributor to apparent TRD. Thus, clinicians treating MDD are urged to search for "soft" signs of bipolarity and to be prepared to alter diagnosis and treatment strategies accordingly.

Suicidality in middle aged and older patients with schizophrenia and depressive symptoms: relationship to functioning and Quality of Life.

BACKGROUND: Suicidality is a health concern in patients with schizophrenia. We examined the hypotheses: (1) Middle aged and older patients with schizophrenia, depressive symptoms and suicidality would exhibit worse quality of life and worse everyday functioning, social skills and medication management relative to those without suicidality; (2) higher levels of suicidality would be significantly associated with worse functioning, worse quality of life and older age. METHODS: We examined 146 outpatients with schizophrenia and depression. Patients were at least 40 years old and were diagnosed with schizophrenia or schizoaffective disorder and had two or more depressive symptoms based on DSM-IV criteria for major depression. We assessed suicidality with the Intersept Suicide Scale (ISS) and functioning with the UCSD Performance-based Skills Assessment (UPSA), Social Skills Performance Assessment (SSPA), and Medication Management Ability Assessment (MMAA). Quality of life was assessed with the Heinrichs Quality of Life Scale (QLS). RESULTS: The mean age of patients was 52.4+ 6.9 years. Subjects with suicidality (ISS scores > 0) had lower QLS scores compared to those without suicidality. However, there were no differences in UPSA, SSPA nor MMAA scores between the two groups. In addition, based on Spearman's rho correlational analysis, there were significant associations of QLS scores with ISS scores (r = - 0.236) and with MMAA "total errors" scores (r = 0.174). Logistic regression demonstrated that only QLS scores predicted suicidality. CONCLUSION: Thirty-six percent of our sample had at least mild degrees of suicidality. Lower quality of life appears to be an important predictor of suicidality.

Preadult onset vs. adult onset of major depressive disorder: a replication study.

OBJECTIVE: In the first 1500 participants with major depressive disorder (MDD) that entered the sequenced treatment alternatives to relieve depression (STAR*D) study, those with preadult onset MDD were more likely to be women and to have a more chronic, severe and disabling form of depression than those with adult onset MDD. This study seeks to replicate these findings. METHOD: The second wave of STAR*D enrollees included 2541 out-patients with MDD, divided into preadult (before age 18) and adult (age 18 or later) onset groups. RESULTS: Participants with a preadult onset of MDD (38%) were younger, ill for longer and more likely to be women than those with adult onset MDD (62%). After adjusting for age, duration of illness and gender, participants with preadult onset MDD also had higher rates of family history of depression, more past suicide attempts, and lower rates of obsessive compulsive and panic disorder. CONCLUSION: Preadult onset MDD may be associated with a more familial form of depression with more suicidality than adult onset MDD.

Citalopram augmentation of antipsychotic treatment in older schizophrenia patients.

BACKGROUND: Depressive symptoms are common in older patients with schizophrenia; yet, few studies have examined the usefulness of antidepressants in this population. OBJECTIVE: We conducted a 10-week single-blind trial of citalopram (20-40 mg/day) vs no citalopram augmentation in 19 middle-aged and elderly patients with schizophrenia hospitalized for more than six of the last 12 months. At study-entry, the patients had been on stable doses of antipsychotics for at least two weeks, and had a 17-item Hamilton Depression Rating (HAM-D) scale score of 12 or greater. Nine patients were randomly assigned to citalopram augmentation, and 10 to no augmentation of antipsychotics. RESULTS: Patients in both groups improved on positive and negative symptoms, but the citalopram group had significantly greater improvement in HAM-D and Clinical Global Impression Scale scores than the control group. There were no major side effects. CONCLUSION: Larger double-blind studies are needed to follow up on these preliminary findings.

Bupropion sustained release for bereavement: results of an open trial.

OBJECTIVE: The present study was conducted to assess whether DSM-IV-defined bereavement responds to bupropion sustained release (SR). METHOD: Twenty-two subjects who had lost their spouses within the previous 6 to 8 weeks and who met DSM-IV symptomatic/functional criteria for a major depressive episode were evaluated. Subjects completed the Hamilton Rating Scale for Depression (HAM-D), the Clinical Global Impressions scale, the Texas Revised Inventory of Grief, and the Inventory of Complicated Grief at baseline and follow-up. Subjects were treated with bupropion SR, 150 to 300 mg/day, for 8 weeks. RESULTS: Improvement was noted in both depression and grief intensity. For the intent-to-treat group. 59% experienced a reduction of > or = 50% on HAM-D scores. The correlations between changes in the HAM-D scores and the grief scale scores were high, ranging from 0.61 (p = .006) to 0.44 (p = .054). CONCLUSION: Major depressive symptoms occurring shortly after the loss of a loved one (i.e., bereavement) appear to respond to bupropion SR. Treatment of these symptoms does not intensify grief; rather, improvement in depression is associated with decreases in grief intensity. The results of this study challenge prevailing clinical wisdom that DSM-IV-defined bereavement should not be treated. Larger, placebo-controlled studies are indicated.

A comparison of community-dwelling older schizophrenia patients by residential status.

OBJECTIVE: Differences in residential status may contribute to the diversity of findings observed in community-based samples of patients with schizophrenia. We compared older out-patients living independently with those in assisted-care facilities. METHOD: Two hundred and fifty-one out-patients with schizophrenia or schizoaffective disorder, aged 40-97 years, who had been referred to our Intervention Research Center were examined. RESULTS: Assisted living status was associated with an earlier age at onset of illness, longer illness duration, lower probability of having ever been married, more severe negative symptoms, worse cognitive impairment, and a poorer health-related quality of wellbeing. Independent living and assisted-care patients had similar levels of positive and depressive symptoms, and were on comparable doses of neuroleptic medication. Significant 'predictors' of residential status were marital status, cognitive impairment and quality of wellbeing. CONCLUSION: Among schizophrenia out-patients, one needs to consider residential status in evaluating heterogeneity in cognitive performance or quality of wellbeing.

An open-label, 12-week clinical and sleep EEG study of nefazodone in chronic combat-related posttraumatic stress disorder.

BACKGROUND: We examined the effects of nefazodone on polysomnographic sleep measures and subjective reports of sleep quality and nightmares. as well as other symptoms, in patients with chronic combat-related posttraumatic stress disorder (PTSD) during a 12-week, open-label clinical trial. To our knowledge, this is the first polysomnographic study of treatment in patients with PTSD. METHOD: The subjects were 12 male veterans (mean age = 54 years) who met DSM-IV diagnostic criteria for PTSD (mean duration = 30 years). All but I patient also met DSM-IV criteria for major depressive disorder. Patients were evaluated weekly with clinical ratings in an open-label clinical trial. Polysomnographic recordings for 2 consecutive nights were obtained before treatment and at 2, 4, 8, and 12 weeks. The dose of nefazodone was adjusted according to individual clinical needs. Final mean daily dose was 441 mg. RESULTS: The patients reported significantly fewer nightmares and sleep problems during treatment. Nevertheless, contrary to studies in depressed patients, nefazodone did not significantly affect polysomnographic sleep measures compared with baseline. In addition, the patients showed significant improvement in the Clinical Global Impressions of PTSD symptoms (global score, hyperarousals and intrusions subscales), the Clinician-Administered PTSD Scale (global, hyperarousal, and intrusions subscales), the Hamilton Rating Scale for Depression (HAM-D). and the Beck Depression Inventory (BDI). CONCLUSION: These patients with chronic, treatment-resistant, combat-related PTSD showed significant improvement of subjective symptoms of nightmares and sleep disturbance, as well as depression and PTSD symptoms. in this 12-week open-label clinical trial. Nevertheless, objective polysomnographic sleep measures did not change. Further studies, including double-blind. placebo-controlled trials, are needed to extend these findings and to understand the relationships between the physiology of sleep and symptoms of poor sleep and nightmares.

Association of depressive symptoms with worse functioning in schizophrenia: a study in older outpatients.

BACKGROUND: Subsyndromal depressive symptoms are highly prevalent and associated with substantial impairments of daily function in the general population. Depressive symptoms are common in schizophrenia. However, few studies have examined the relationship of functioning and well-being to the presence of depressive symptoms in schizophrenia. METHOD: 202 middle-aged or elderly outpatients with schizophrenia (DSM-III-R or DSM-IV criteria) were categorized by severity of depressive symptoms on the Hamilton Rating Scale for Depression (HAM-D) using previously validated cutoff points, i.e., HAM-D total score < or = 6 (low), from 7 to 16 (medium), and > or = 17 (high). We also assessed severity of positive and negative symptoms, movement disorders, neurocognitive performance, daily functioning, and health-related quality of well-being with standardized measures. RESULTS: A total of 11.4% of patients had HAM-D scores > or = 17, and 56.4% had HAM-D scores from 7 to 16. Even after adjusting for severity of other psychopathology, patients with more severe depressive symptoms had significantly worse everyday functioning (p < .02), except for physical functioning, and health-related quality of well-being (r = -.365, p < .001) than did those with lower HAM-D scores. These differences were unrelated to those in demographics, extrapyramidal symptoms, tardive dyskinesia, neurocognitive performance, or number of physical illnesses. CONCLUSION: The results suggest the importance of evaluating schizophrenia patients for the presence of depressive symptoms. Effectiveness of adjunct treatment of depressive symptoms with antidepressants and psychosocial management in improving functioning of schizophrenia patients deserves further study.

Cross-sectional study of older outpatients with schizophrenia and healthy comparison subjects: no differences in age-related cognitive decline.

OBJECTIVE: Little is known about the progression of cognitive deficits in older, community-dwelling patients with schizophrenia, especially in comparison to healthy subjects. METHOD: The authors examined the relationship of age to performance on the Mattis Dementia Rating Scale in 116 outpatients with schizophrenia and 122 normal comparison subjects. Subjects ranged in age from 40 to 85 years. RESULTS: Dementia Rating Scale scores were lower in the schizophrenia group but correlated negatively with age in both groups, with no significant differences seen between the schizophrenia and normal comparison groups in slopes that depicted age-related variation. CONCLUSIONS: This cross-sectional study suggests a relatively stable long-term course of cognitive impairment in individuals with schizophrenia, with no evidence of faster cognitive decline in outpatients with schizophrenia than in normal comparison subjects.

The influence of HIV-related support groups on survival in women who lived with HIV. A pilot study.

To determine the effect of support groups on survival, the authors retrospectively studied 21 HIV-seropositive women who died during the course of participation in a natural history study of HIV. Groups were composed of women who self-selected HIV support groups before death (n = 11) and a comparison group (n = 10). Survival analysis found group participation to be associated with increased longevity (73 months vs. 45 months; P = 0.011). Proportional-hazards regression demonstrated that HIV-related support groups and smaller family size significantly influenced survival (P = 0.0002). Factors related to group participation and ways in which support groups might promote longevity are discussed.

Nefazodone in patients with treatment-refractory posttraumatic stress disorder.

BACKGROUND: Posttraumatic stress disorder (PTSD) is a highly prevalent and often chronic disorder among combat veterans, persisting in as many as 15% of Vietnam veterans for at least 20 years. Treatment response in veterans with combat-related PTSD has been disappointing. Although anxiolytics, anticonvulsants, antipsychotics, and antidepressants have been tried, none has been consistently associated with improvement in all primary symptom domains (i.e., intrusive recollections, avoidance/numbing, and hyperarousal). This open-label study evaluated the use of nefazodone in a group of Vietnam veterans with chronic, treatment-refractory symptoms of PTSD. METHOD: Male outpatients with DSM-IV PTSD who had failed a minimum of 3 previous medication trials were eligible for the study. Nineteen Vietnam combat veterans entered the study and were treated with nefazodone, 100-600 mg/day, for 12 weeks. PTSD symptoms, anxiety, depression, sleep, sexual functioning, and adverse events were assessed weekly. RESULTS: Severity of depression lessened, as did PTSD symptoms of intrusive recollections, avoidance, and hyperarousal. Depressive symptom severity as measured by the Beck Depression Inventory decreased by a mean of 30%. Similarly, there was an overall drop in the intensity of PTSD symptoms as measured by the Clinician Administered PTSD Scale of 32% with a 26% improvement for symptoms of intrusion, 33% for avoidance, and 28% for arousal. In addition, improvements in sleep and sexual functioning were reported. The mean daily dose of nefazodone after 12 weeks was 430 mg (range, 200-600 mg/day). The most frequently reported side effects were headaches (53%), dry mouth (42%), and diarrhea (42%), but side effects tended to be mild and transient. CONCLUSION: In this group of Vietnam veterans with chronic treatment-refractory PTSD and multiple comorbid Axis I psychiatric disorders, nefazodone was well tolerated and effective. Larger, controlled studies are warranted.

The psychological and physical health of hospice caregivers.

This study explores the psychological distress of caring for a dying family member and examines the differences in depression, anxiety, health, social and occupational functioning, and social support among hospice caregivers and community controls. It compares psychological functioning of spousal and adult child hospice caregivers. Caregivers of terminally ill hospice patients were assessed prior to death as a part of a longitudinal bereavement study. Caregivers reported experiencing higher levels of depression, anxiety, anger, and health problems than controls. Hospice caregiving was associated with deterioration in physical health and in social and occupational functioning. The comparisons between adult children and spouse caregivers revealed that levels of psychological and physical morbidity were very similar for the two generations of caregivers. An awareness of distress symptoms among hospice caregivers could lead to timely proactive clinical intervention that may prevent bereavement complications.

Does an increase in sulcal or ventricular fluid predict where brain tissue is lost?

Quantitative volumes of cerebrospinal fluid (CSF) and brain tissue were measured on magnetic resonance images (MRIs) of 287 individuals from 5 diagnostic groups: Alzheimer's disease (AD), chronic alcoholics (ALC), individuals positive for human immunodeficiency virus (HIV), schizophrenia subjects (SZ), and normal comparison subjects (NC) older than 50 years of age. Within each group, mean volumes were calculated for ventricular CSF, cortical (sulcal) CSF, cortical gray matter, total white matter, basal ganglia gray matter, and thalamic gray matter. Correlations of CSF measures with brain tissue measures were determined, and multiple regression analyses were performed to try and predict volume of gray matter or white matter region from volume of CSF compartment. Results indicated the following: 1. Enlarged cortical fluid volume significantly predicts cortical gray matter deficits for subjects with AD and those who are ALC and SZ but not for subjects with HIV or NC. 2. Enlarged cortical fluid volume also significantly predicts white matter deficits in all five groups. 3. Enlarged ventricular fluid volume significantly predicts basal ganglia deficits in AD, HIV, and NC but not in SZ or ALC. 4. Enlarged ventricular volume has no predictive value for thalamic volume for any of the groups. This study supports the clinical practice of predicting brain tissue volume loss from CSF enlargement but not for all brain regions in all diagnoses.

Depressive symptoms in schizophrenia.

OBJECTIVE: The authors assessed the presence and severity of depressive symptoms, as well as their associations with other clinical measures, in a group of mid- to late-life patients with schizophrenia who were not in a major depressive episode or diagnosed with schizoaffective disorder. METHOD: Sixty outpatients with schizophrenia between the ages of 45 and 79 years and 60 normal comparison subjects without major neuropsychiatric disorders, proportionally matched for age and gender, were studied. Depressive symptoms were rated primarily with the Hamilton Depression Rating Scale. Standardized instruments were also used to measure global psychopathology, positive and negative symptoms, abnormalities of movement, and global cognitive status. RESULTS: Depressive symptoms were more frequent and more severe in schizophrenic patients than in normal comparison subjects; 20% of the women with schizophrenia had a Hamilton depression scale score of 17 or more. Severity of depressive symptoms correlated with that of positive symptoms but not with age, gender, negative symptoms, extrapyramidal symptoms, or neuroleptic dose. CONCLUSIONS: Depressive symptoms are common in older patients with schizophrenia. They may be an independent, core component of the disorder or, alternatively, may be a by-product of severe psychotic symptoms.

Effects of noradrenergic and serotonergic antidepressants on chronic low back pain intensity.

To understand the relative efficacy of noradrenergic and serotonergic antidepressants as analgesics in chronic back pain without depression, we conducted a randomized, double-blind, placebo-control head-to-head comparison of maprotiline (a norepinephrine reuptake blocker) and paroxetine (a serotonin reuptake blocker) in 103 patients with chronic low back pain. Of these 74 completed the trial; of the 29 who did not complete, 19 were withdrawn because of adverse effects. The intervention consisted of an 8-week course of maprotiline (up to 150 mg daily) or paroxetine (up to 30 mg daily) or an active placebo, diphenhydramine hydrochloride (up to 37.5 mg daily). Patients were excluded for current major depression. Reduction in pain intensity (Descriptor Differential Scale scores) was significantly greater for study completers randomized to maprotiline compared to placebo (P=0.023), and to paroxetine (P=0.013), with a reduction of pain by 45% compared to 27% on placebo and 26% on paroxetine. These results suggest that at standard dosages noradrenergic agents may provide more effective analgesia in back pain than do selective serotonergic reuptake inhibitors.

Nefazodone in post-traumatic stress disorder: results from six open-label trials.

Nefazodone, an antidepressant which blocks serotonin (5-HT)2 receptors and 5-HT reuptake, was evaluated in the treatment of post-traumatic stress disorder (PTSD) in six open-label studies involving both civilians and combat veterans. Our objective was to report this available pooled data to characterize the response of this drug in PTSD. Specifically, we looked at response rates using three different criteria, the effect of nefazodone on each PTSD cluster and individual symptoms and, lastly, variables that might predict response. One hundred and five outpatients with chronic PTSD were treated with nefazodone titrated up to 600 mg/day, 92 of whom were entered in an intent to treat analysis. We used the percentage drop in score between baseline and endpoint on main scale as a common measure to evaluate outcome. The response criterion of a drop in score of at least 30%, 40% and 50% revealed response rates of 46, 36 and 26%, respectively. Nefazodone showed a broad spectrum of action on PTSD symptoms. This profile might make nefazodone a useful drug to treat PTSD. Predictors of response include age, sex and trauma type. Double-blind, placebo-controlled clinical trials in PTSD are in progress to assess the utility of nefazodone as a treatment in this disorder.

Consensus criteria for traumatic grief. A preliminary empirical test.

BACKGROUND: Studies suggest that symptoms of traumatic grief constitute a distinct syndrome worthy of diagnosis. AIMS: A consensus conference aimed to develop and test a criteria set for traumatic grief. METHOD: The expert panel proposed consensus criteria for traumatic grief. Receiver operator characteristic (ROC) analyses tested the performance of the proposed criteria on 306 widowed respondents at seven months post loss. RESULTS: ROC analyses indicated that three of four separation distress symptoms (e.g. yearning, searching, loneliness) had to be endorsed as at least 'sometimes true' and four of the final eight traumatic distress symptoms (e.g. numbness, disbelief, distrust, anger, sense of futility about the future) had to be endorsed as at least 'mostly true' to yield a sensitivity of 0.93 and a specificity of 0.93 for a diagnosis of traumatic grief. CONCLUSIONS: Preliminary analyses suggest the consensus criteria for traumatic grief have satisfactory operating characteristics, and point to directions for further refinement of the criteria set.
