Latent class analysis differentiation of adjustment disorder and demoralization, more severe depressive and anxiety disorders, and somatic symptoms in patients with cancer.

OBJECTIVES: Demoralization as a form of existential distress involves poor coping, low morale, hopelessness, helplessness, and meaninglessness. In a secondary analysis of a cohort of German cancer patients, we aimed to explore latent class structure to assess the contribution that symptoms of demoralization make to anhedonic depression, anxiety, adjustment, and somatic disorders. METHODS: Measures of demoralization, depression, anxiety, physical symptoms, and functional impairment had been completed cross-sectionally by 1527 patients with early or advanced cancer. Latent class analysis used maximum likelihood techniques to define the unobserved latent constructs that can be predicted as symptom clusters. Individual patients were assigned to the most probable class. Classes were compared on demographics, and logistic regression assessed the odds of individual items predicting each class. RESULTS: A 4-class model provided the best fit. Class 1 (n = 829, 54.3%) was defined by the absence of distress; Classes 2 to 4 all carried functional impairment. Class 2 (n = 333, 21.8%) was differentiated by somatic symptoms (sleep, tiredness, and appetite); Class 3 (n = 163, 10.7%) by anhedonia, anxiety, and severe demoralization; and Class 4 (n = 202, 13.2%) by adjustment and moderate demoralization. Members of Class 3 were more likely to be younger, female, anhedonic, depressed, and anxious. In both Classes 3 and 4, functional impairment, physical symptom burden, and suicidal ideation were present. CONCLUSIONS: In contrast with the severe symptom cluster carrying anhedonia, anxiety, and demoralization, the moderate symptom cluster was formed by patients with demoralization and impaired functioning, a clinical picture consistent with a unidimensional model of adjustment disorder.

The impact of sexual orientation on body image, self-esteem, urinary and sexual functions in the experience of prostate cancer.

Prostate cancer (PCa) poses a large health burden globally. Research indicates that men experience a range of psychological challenges associated with PCa including changes to identity, self-esteem and body image. The ways in which sexual orientation plays a role in the experience of PCa, and the subsequent impact on quality of life (QoL), body image and self-esteem have only recently been addressed. By addressing treatment modality, where participant numbers were sufficient, we also sought to explore whether gay (homosexual) men diagnosed with PCa (PCaDx) and with a primary treatment modality of surgery would report differences in body image and self-esteem compared with straight (heterosexual) men with PCaDx with a primary treatment modality of surgery, compared with gay and straight men without PCaDx. The results of our study identified overall differences with respect to PCaDx (related to urinary function, sexual function and health evaluation), and sexual orientation (related to self-esteem), rather than interactions between sexual orientation and PCaDx. Gay men with PCaDx exhibited higher levels of urinary functioning than straight men with PCaDx, the difference being reversed for gay and straight men without PCaDx; but this result narrowly failed to achieve statistical significance, suggesting a need for further research, with larger samples.

The meaning of a high plasma free haemoglobin: retrospective review of the prevalence of haemolysis and circuit thrombosis in an adult ECMO centre over 5 years.

AIMS: In adults requiring extracorporeal membrane oxygenation (ECMO), we wanted to determine; i) the frequency of elevated plasma free haemoglobin (PFHb), ii) the reasons for circuit changes and iii) whether elevated PFHb was associated with higher in-hospital mortality. MATERIALS AND METHODS: Patients requiring ECMO between January 2010 and August 2014 were identified from a prospectively collected ECMO database. Their scanned medical records and pathology results were reviewed. Relevant patient, biochemical and circuit data were collected on an Excel spreadsheet and analysed using Stata 13 (StataCorp, College Station, TX). The patients were analysed in three groups, depending on their peak PFHb during ECMO: 'Normal PFHb' (<0.1 g/L), 'Low level PFHb' (0.1 - 0.5 g/L), 'High level PFHb' (>0.5 g/L). MAIN RESULTS: There were 184 ECMO runs (56 VV, 128 VA) - 61 'Normal PFHb', 99 'Low level PFHb', 24 'High level PFHb'. Circuit thrombosis (pump, oxygenator) or haemolysis requiring exchanges were significantly more common in VV ECMO compared to VA ECMO - 23.21% (13/56) vs. 0.78% (1/128), p<0.001. Elevated PFHb was associated with a longer duration of haemofiltration (p<0.001) and ECMO support (p<0.001). In-hospital mortality rates for the 'Normal PFHb', 'Low level PFHb' and 'High level PFHb' groups were 16.39% (10/61), 30.30% (30/99) and 37.50% (9/24), respectively, p=0.067. CONCLUSION: Elevated PFHb values during adult ECMO were common. Severe haemolysis or thrombosis requiring circuit changes were uncommon and occurred almost exclusively on VV ECMO. There was a non-statistically significant increase in in-hospital mortality with elevated PFHb and studies of larger registry data may clarify the prognostic value of PFHb in adult patients.

Major depression and depressive symptoms in Australian Gulf War veterans 20 years after the Gulf War.

BACKGROUND: Risk of major depression (depression) was elevated in Australia's Gulf War veterans in a 2000-2002 (baseline) study. A follow up study has measured the Gulf War-related risk factors for depression, also the current prevalence and severity of depression, use of anti-depressant medication, and persistence, remittance or incidence of depression since baseline in Gulf War veterans and a military comparison group. METHODS: Participants completed the Composite International Diagnostic Interview v.2.1, the 9-item Patient Health Questionnaire and the Military Service Experience Questionnaire, and consented to Repatriation Pharmaceutical Benefits Scheme (RPBS) and PBS linkage. RESULTS: Prevalence of depression (9.7% Gulf War veterans and 7.7% comparison group; adj RR=1.2, 95% CI 0.8-1.7), and pattern of persistence, remittance and incidence of depression since baseline, were similar in the two groups, however veterans reported slightly more severe symptoms (adj median difference 1, 95% CI 0.26-1.74) and were more likely to have been dispensed anti-depressant medication (adj RR=1.56, 95% CI 1.05-2.32). Depression amongst veterans was associated with self-reported Gulf War-related stressors in a dose-response relationship (adj RR 1.06, 95% CI 1.02-1.09). LIMITATIONS: Lower participation rates at follow up resulted in reduced statistical power compared with baseline, Gulf War related stressor data collected at baseline was at risk of recall bias, and RPBS and PBS databases do not capture all dispensed Nervous System medications. CONCLUSIONS: More than 20 years after the Gulf War, veterans are experiencing slightly more severe depressive symptoms than a military comparison group, and depression continues to be associated with Gulf War-related stressors.

Postnatal demoralisation among women admitted to a hospital mother-baby unit: validation of a psychometric measure.

Demoralisation is a psychological state characterised by experiences of distress and sadness, helplessness, subjective incompetence and hopelessness, in the context of a stressful situation. Experiences of demoralisation may be particularly relevant to women who have recently given birth, who can feel incompetent, isolated and helpless. The psychometric properties of the Demoralisation Scale among women in the postnatal period participating in a clinical program were examined. Women admitted with their infants to a hospital mother-baby unit in Australia for five nights were recruited consecutively (N = 209) and assessed at admission and discharge. The Demoralisation Scale was perceived as relevant and exhibited high reliability, acceptable construct validity and good sensitivity to change. The mean demoralisation score was high (M = 30.9, SD = 15.5) and associated with negative experiences of motherhood and functional impairment, independent of depression and anxiety symptoms. Mean demoralisation decreased significantly after program completion (M = 18.4, SD = 12.4). More participants showed a significant improvement in demoralisation (57.5 %) than in depression (34.8 %) and anxiety (9.8 %) symptoms. Demoralisation can provide a useful framework for understanding and measuring the experiences of women participating in postnatal clinical programs and in directing treatment towards helping women to acquire the necessary caregiving skills and increasing parental efficacy. The Demoralisation Scale is a useful clinical tool for assessing intervention effects.

Life satisfaction and quality in Korean War veterans five decades after the war.

BACKGROUND: Military service is considered to be a hidden variable underlying current knowledge about well-being in the elderly. This study aimed to examine life satisfaction and quality of life in Australia's surviving male Korean War veterans and a community comparison group, and to investigate any association with war deployment-related factors. METHODS: Participants completed a postal questionnaire which included the Life Satisfaction Scale, the brief World Health Organization Quality of Life (WHOQOL-Bref) questionnaire and the Combat Exposure Scale. RESULTS: Korean War veterans reported significantly lower Percentage Life Satisfaction (PLS) and quality of life scores on four WHOQOL-Bref domains, compared with similarly aged Australian men (each p value <0.001). These outcomes were most strongly associated with severity of combat exposure and low rank. Mean PLS was approximately 15% lower in veterans who reported heavy combat compared with those reporting no combat, and approximately 12% lower in enlisted ranked veterans compared with officers. CONCLUSIONS: Fifty years after the Korean War, life satisfaction and quality in Australian veterans is poor relative to other Australian men, and is associated with deployment-related factors including combat severity and low rank. In order to respond effectively to current and projected population health needs, nations with large veteran populations may need to consider the impact of military service on well-being in later life.

Symptoms and medical conditions in Australian veterans of the 1991 Gulf War: relation to immunisations and other Gulf War exposures.

AIMS: To investigate whether Australian Gulf War veterans have a higher than expected prevalence of recent symptoms and medical conditions that were first diagnosed in the period following the 1991 Gulf War; and if so, whether these effects were associated with exposures and experiences that occurred in the Gulf War. METHODS: Cross-sectional study of 1456 Australian Gulf War veterans and a comparison group who were in operational units at the time of the Gulf War, but were not deployed to that conflict (n = 1588). A postal questionnaire was administered and the likelihood of the diagnosis of self-reported medical conditions was assessed and rated by a medical practitioner. RESULTS: Gulf War veterans had a higher prevalence of all self-reported health symptoms than the comparison group, and more of the Gulf War veterans had severe symptoms. Increased symptom reporting was associated with several exposures, including having more than 10 immunisations, pyridostigmine bromide tablets, anti-biological warfare tablets, pesticides, insect repellents, reportedly being in a chemical weapons area, and stressful military service experiences in a strong dose-response relation. Gulf War veterans reported psychological (particularly post-traumatic stress disorder), skin, eye, and sinus conditions first diagnosed in 1991 or later more commonly than the comparison group. Over 90% of medical conditions reported by both study groups were rated by a medical practitioner as having a high likelihood of diagnosis. CONCLUSION: More than 10 years after the 1991 Gulf War, Australian veterans self-report all symptoms and some medical conditions more commonly than the comparison group. Further analysis of the severity of symptoms and likelihood of the diagnosis of medical conditions suggested that these findings are not due to over-reporting or to participation bias.

The health of Australian veterans of the 1991 Gulf War: factor analysis of self-reported symptoms.

BACKGROUND: A recent report showed that Australian veterans of the 1991 Gulf War displayed a greater prevalence of a multitude of self-reported symptoms than a randomly sampled comparison group of military personnel who were eligible for deployment but were not deployed to the Gulf. AIMS: To investigate whether the pattern, rather than frequency, of symptom reporting in these Australian Gulf War veterans differed from that of the comparison group personnel. METHODS: Factor analysis was used to determine whether the co-occurrence of 62 symptoms in 1322 male Gulf War veterans can be explained by a number of underlying dimensions, called factors. The methodology was also applied to 1459 male comparison group subjects and the factor solutions of the two groups were compared. RESULTS: For the Gulf War veterans, a three factor solution displayed replicability and construct validity. The three factors were labelled as psycho-physiological distress, somatic distress, and arthro-neuromuscular distress, and were broadly similar to those described in previous studies of Gulf War veterans. A concordant three factor solution was also found for the comparison group subjects, with strong convergence of the factor loadings and factor scores across the two groups being displayed. CONCLUSION: Results did not display evidence of a unique pattern of self-reported symptoms among Gulf War veterans. Results also indicated that the differences between the groups lie in the degrees of expression of the three underlying factors, consistent with the well documented evidence of increased self-reported symptom prevalence in Gulf War veterans.

Respiratory health status of Australian veterans of the 1991 Gulf War and the effects of exposure to oil fire smoke and dust storms.

BACKGROUND: Since the 1991 Gulf War concerns have been raised about the effects on veterans' health of exposures to Kuwaiti oil fire smoke and to dust storms. METHODS: A cross sectional study compared 1456 Australian Gulf War veterans with a randomly sampled military comparison group (n = 1588). A postal questionnaire asked about respiratory conditions, exposures, medications, tobacco use, demographic characteristics, and military service details. During a medical assessment, spirometric tests and a physical examination were performed and a respiratory questionnaire was administered. RESULTS: The response rate for the Gulf War veteran group was 80.5% and for the comparison group 56.8%. Australian Gulf War veterans had a higher than expected prevalence of respiratory symptoms and respiratory conditions suggesting asthma (OR 1.4; 95% CI 1.1 to 1.9) and bronchitis first diagnosed since the Gulf War (OR 1.9; 95% CI 1.2 to 3.1) but did not have poorer lung function or more ventilatory abnormalities than the comparison group. Veterans who reported exposure to oil fire smoke had slightly poorer forced vital capacity (difference between means -0.10 l; 95% CI -0.18 to -0.03) and those exposed to dust storms had a slightly better peak expiratory flow rate (difference between means 12.0 l/min; 95% CI 0.6 to 23.4) than veterans who did not report exposure. Veterans who were in the Gulf at or after the start of the oil fires had more respiratory conditions suggesting asthma (OR 1.7; 95% CI 1.0 to 2.9) than those who completed their deployment before this time. CONCLUSIONS: Increased self-reporting of respiratory symptoms, asthma, and bronchitis by veterans was not reflected in poorer lung function. The findings do not suggest major long term sequelae of exposure to oil fire smoke or dust storms.

Psychological health of Australian veterans of the 1991 Gulf War: an assessment using the SF-12, GHQ-12 and PCL-S.

BACKGROUND: Elevated rates of psychological morbidity and symptomatology have been widely reported in 1991 Gulf War veterans. The present study used brief self-report instruments to compare the psychological health of Australian Gulf War veterans with that of a randomly sampled military comparison group. METHOD: The 12-item Short Form Health Survey (SF-12), 12-item General Health Questionnaire (GHQ-12), Posttraumatic Stress Disorder Checklist--Specific (PCL-S) and Military Service Experience (MSE) questionnaire were administered to 1424 male Australian Gulf War veterans and 1548 male Australian Defence Force members who were operational at the time of the Gulf War conflict, but were not deployed there. RESULTS: The Gulf War veterans exhibited poorer psychological health, as measured by the above three instruments, than the comparison group members. For Gulf War veterans, the number of stressful experiences, as measured by the MSE questionnaire, was correlated with scores on the three instruments. SF-12 mental health component summary scores and PCL-S caseness, but not GHQ-12 caseness, differed significantly between Gulf War veterans and comparison group members who had been on at least one active deployment. CONCLUSIONS: More than a decade after the 1991 Gulf War, Australian Gulf War veterans are exhibiting higher levels of current (past month) psychological ill-health, as measured using the GHQ-12 and PCL-S, as well as lower mental health status, as measured by the SF-12, than the comparison group. Although not a replacement for formal psychiatric diagnosis, instruments such as those above may aid in the assessment of veterans' psychological health.

Consultation-liaison psychiatrists' management of somatoform disorders.

The authors studied interventions recommended by consultation-liaison (C-L) psychiatrists when they diagnosed somatoform disorder prospectively in a cohort of 4,401 consecutive inpatients referred to the C-L psychiatry service of a general teaching hospital, using standardized MICRO-CARES methodology. A DSM-III-R somatoform disorder was diagnosed in 2.9%, somatoform pain disorder in 1.4%, conversion disorder in 0.7%, hypochondriasis or somatization disorder undifferentiated/not otherwise specified in 0.6%, and somatization disorder in 0.2%. In 3.4%, somatoform disorder was considered a differential diagnosis. Psychiatric comorbidity included mood disorder (39%), personality disorder (37%), and psychoactive substance use disorder (19%). Recommendations were made about antidepressants in 40% of the patients, anxiolytics in 18%, sedatives in 18%, and antipsychotics in 10%. Psychiatrists recommended the following: more laboratory tests for 14%; additional medical/surgical consultations for 11%; an increase in the vigor of medical treatment for 13%; and psychological treatment for 76%; also they stressed an earlier discharge of 16%. Psychiatrists were more likely to request a prolongation of inpatient stay for patients with comorbid somatoform, mood, anxiety, and personality disorder. Differences in characteristics and treatment of the subgroups tended to be consistent with their constructs and comorbid psychiatric diagnoses.

Dimensions of psychopathology in the medically ill. A latent trait analysis.

The authors examined the latent structure of psychiatric symptoms occurring in patients with medical illness. Symptom data were collected from 312 hospitalized medically ill patients using the Monash Interview for Liaison Psychiatry and subjected to latent trait analysis. A model with 5 dimensions provided an acceptable fit to the data. Dimensions were characterized as demoralization, anhedonia, autonomic anxiety, somatic symptoms, and grief. The demoralization dimension was similar to the concept of demoralization described by Frank and to the "giving up-given up complex" described by Engel. The concepts of demoralization, grief, and anhedonia may be useful in increasing understanding of the minor depressions in people with medical illness and in increasing the specificity of psychological and pharmacological treatments for these disorders.

Continuity of contact with psychiatric services: immigrant and Australian-born patients.

BACKGROUND: Under-representation of ethnic minority groups in psychiatric services has been widely reported in Western nations. The present study examined whether there were differences between immigrant and Australian-born patients in their maintenance of contact with a statewide psychiatric service system. METHODS: Groups were selected on the empirical grounds that they are differently represented in this service system. Employing a form of case-control design, four groups of patients were compared: those born in Australia, the United Kingdom, Southern Europe, and South East/East Asia respectively (n = 79 for each). Groups were identically matched on sex, age, diagnosis (either schizophrenia or bipolar illness) and locality of service. The groups did not differ as to the timing of their first appearance in the 3-year period in which their psychiatric contact was examined. RESULTS: Despite their different representation in the psychiatric service system, the four groups did not differ on measures of continuity of contact. Measures included number of contacts with mental health community services, number of admissions to inpatient wards, length of stay in hospital and the longest interval between any two successive service contacts. CONCLUSIONS: The commonly reported underrepresentation of immigrant groups in the psychiatric service system does not appear to be due to greater discontinuation of contact with services. If the assumption of equal community prevalence of disorder is made, then the observed under-representation may be due to differential rates of access to (that is, initial contact with) psychiatric services.

The influence of client's ethnicity on psychotropic medication management in community mental health services.

OBJECTIVES: The aim of this study was to investigate whether people born in non-English-speaking countries differed from clients born in Australia on quality of medication management, measured by mean neuroleptic dose, method of administration, use of atypical antipsychotics and perceived compliance with medication, and to investigate the influence of matching the client with a case manager from the same ethnic background on these measures. METHOD: Information about medication and perceived compliance was provided for 168 clients of five community mental health services in Melbourne. Chlorpromazine equivalent doses (CPZe) were calculated, and average dose, route of administration, percentage receiving atypical antipsychotics and perceived compliance with medication were analysed by country of birth and preferred language. Each analysis was repeated for clients matched to a case manager from the same ethno-linguistic background compared to those with 'unmatched' case managers. RESULTS: While non-English-speaking background (NESB) clients generally did not receive different dose sizes, those born in Vietnam had a lower mean dose. People born in a non-English-speaking country tended to be more likely than the Australian born to receive a depot injection, although this was not quite statistically significant. Twenty-seven percent of clients received an atypical neuroleptic; age was a significant factor, with older clients less likely to receive an atypical. There was no difference in receipt of atypicals or perceived compliance by country of birth, language or gender. Matching for a case manager of the same background had no effect except for route of administration, with matched clients less likely to receive depot medication than unmatched. CONCLUSIONS: Generally, the ethnic background of clients had little influence on the quality of medication management they received from community mental health services.

Psychological morbidity and quality of life in Australian women with early-stage breast cancer: a cross-sectional survey.

OBJECTIVE: To determine the prevalence of psychological morbidity and describe quality of life in women with early-stage breast cancer. DESIGN: Cross-sectional descriptive study (3 months after conservative breast surgery or mastectomy) of patients from nine general hospitals in Melbourne, Victoria, October 1994 to March 1997. PARTICIPANTS: 303 women with early-stage breast cancer entering a randomised trial of adjuvant psychological group therapy; mean age, 46 years (SD, 8). MAIN OUTCOME MEASURES: Diagnostic and Statistical Manual of Mental Health (DSM)-IV psychiatric diagnoses generated by the Monash Interview for Liaison Psychiatry; quality-of-life data based on the the European Organization for Research and Treatment of Cancer quality-of-life questionnaire (QLQ)-C30 (core) and QLQ-BR23 (breast module) instruments. RESULTS: 45% of the women (135/303) had a psychiatric disorder; 42% (127) of the sample had depression or anxiety, or both; there was minor depression in 82 (27.1%), an anxiety disorder in 26 (8.6%), major depression in 29 (9.6%) and a phobic disorder in 21 (6.9%). 20% of women (61) had more than one disorder. On quality-of-life measures nearly one-third of the women felt less attractive and most had lost interest in sexual activity. There was substantial distress about hair loss. Symptoms of lymphoedema were described by 13 women (4.3%). Breast conservation surgery was associated with a better body image (P<0.01). CONCLUSION: Women recently diagnosed with early-stage breast cancer have high rates of psychiatric and psychological disturbance. Quality of life is substantially affected. Clinicians should actively explore their patients' psychological adjustment to enable early recognition and treatment of these disorders.

Monash Interview for Liaison Psychiatry (MILP). Development, reliability, and procedural validity.

The Monash Interview for Liaison Psychiatry (MILP) is a structured interview designed for use with patients who have physical and psychiatric comorbidity. Linked to a computerized diagnostic algorithm, the MILP is able to establish diagnoses according to DSM-III-R, International Classification of Diseases--10th Edition (ICD-10), and DSM-IV criteria, as well as a range of other criteria relevant to consultation-liaison psychiatry. Interrater reliability was assessed with 54 joint interviews, in which the mean kappa for agreement of items was 0.83 and of diagnoses was 0.68. Comparative procedural validity was tested against DSM-III-R decision-tree diagnoses, ICD-10 checklist diagnoses, and Structured Clinical Interview for DSM-III-R interview diagnoses on another sample of 54 patients. Mean kappas for these comparisons were 0.61, 0.56, and 0.31, respectively. As predicted, the MILP more fully covered the spectrum of somatizing disorders, compared with the other methods for establishing diagnoses.

Adjustment disorder: a multisite study of its utilization and interventions in the consultation-liaison psychiatry setting.

The consultation-liaison (C-L) psychiatry services of seven university teaching hospitals in the United States, Canada, and Australia (the MICRO-CARES Consortium) used a common clinical database to examine 1039 consecutive referrals. A diagnosis of adjustment disorder (AD) was made in 125 patients (12.0%); as the sole diagnosis, in 81 (7.8%); and comorbidly with other Axis I and II diagnoses in 44 (4.2%). It had been considered as a rule-out diagnosis in a further 110 (10.6%). AD with depressed mood, anxious mood, or mixed emotions were the commonest subcategories used. AD was diagnosed comorbidly most frequently with personality disorder and organic mental disorder. Sixty-seven patients (6.4%) were assigned a V code diagnosis only. Patients with AD were referred significantly more often for problems of anxiety, coping, and depression; had less past psychiatric illness; and were rated as functioning better--all consistent with the construct of AD as a maladaptation to a psychosocial stressor. Interventions were similar to those for other Axis I and II diagnoses, in particular, the prescription of antidepressants. Patients with AD required a similar amount of clinical time and resident supervision. It is concluded that AD is an important and time-consuming diagnostic category in C-L psychiatry practice.

Organic mental disorders in the consultation-liaison psychiatry setting. A multi-site study.

Interventions recommended by consultation-liaison psychiatrists for inpatients they diagnosed as having DSM-III-R organic mental disorder (OMD) were studied to see to what extent specific variables distinguished the OMD patients and differentiated the subgroups of patients with OMD. Prospective data and Mini-Mental State Exam (MMSE) scores on 625 consecutive referrals at 3 general hospitals in Australia and the United States were collected by using the MICRO-CARES database system. The OMD group differed from the other patients because they were significantly more likely to have been referred for "organic brain syndrome" or "agitation," had less mood disorder and lower MMSE scores, and received more recommendations for antipsychotics and for ward-environment manipulation and fewer recommendations for psychological management. The many differences among the OMD subgroups were also consistent with their DSM constructs. A pilot exploration of the validity of the DSM-IV constructs of cognitive disorder and its subgroups performed on the redistributed data suggested that these constructs have similar usefulness.

The bereavement phenomenology questionnaire: a single factor only.

OBJECTIVE: To review the psychometric properties and factor structure of the Bereavement Phenomenology Questionnaire (BPQ). METHOD: Continuous data were compared using two tailed t-tests and analysis of variance. A confirmatory factor analysis was carried out. RESULTS: Good internal consistency (Cronbach's alpha = 0.93) with a single factor has been found. The BPQ discriminates the intensity of grief between widows and widowers, spouses and offspring, and temporally between acute and later phases of bereavement. CONCLUSION: Although on the BPQ items are highly correlated and only a single factor has emerged, it remains nonetheless a valid and reliable scale for the measurement of grief.
