Background: Most general practitioners (GPs) are currently treating a small number of patients with schizophrenia; however, little is known about GPs' experiences in this area. This paper examines the attitudes and roles of Australian GPs in the treatment of schizophrenia and their relationships with specialist services., Methods: A total of 192 GPs' ratings of possible sources and forms of help for patients with schizophrenia were compared with the ratings of 50 mental health services (MHS) staff and 129 patients. Comparisons within the health professionals were also made in relation to diagnostic and treatment confidence, perceived roles, and typical problems encountered., Results: Perceived helpfulness ratings were reasonably consistent across groups. However, patients tended to rank close family members as more helpful. GPs and MHS staff reported complementary roles, with a shared responsibility for early detection and relapse prevention. Treatment compliance, and communication and accessibility to specialist agencies were identified as major problems., Conclusions: GPs fulfil a valuable role in the treatment of schizophrenia, which could be enhanced through improved training. Mental health services need to work more effectively with GPs in treating schizophrenia and acknowledge their complementary roles.

Objective: To survey the attitudes of Australian medical students to determine their views about the relative attractiveness of psychiatry as a career compared with other specialties, and against findings from a North American study., Method: We surveyed 655 first-year medical students attending six Australian Universities., Results: Responses indicated that Australian medical students view psychiatry as distinctly less 'attractive' than other career options, as reported in the North American sample. In comparison with other disciplines, psychiatry was regarded as more interesting and intellectually challenging, but also as lacking a scientific foundation, not being enjoyable and failing to draw on training experiences., Conclusion: Our findings suggest that psychiatry has an image problem that is widespread, reflecting community perceptions and the specialist interests of medical students on recruitment. If psychiatry is to improve its 'attractiveness' as a career option, identified image problems need to be corrected and medical student selection processes re-considered.

Objective: This study assessed 12-month service use patterns among people with psychotic disorders and sought to identify determinants of service use., Methods: As part of a large two-phase Australian study of psychotic disorders, structured interviews were conducted with a stratified random sample of adults who screened positive for psychosis. Demographic characteristics, social functioning, symptoms, mental health diagnoses, and use of psychiatric and nonpsychiatric services were assessed. Data were analyzed for 858 persons who had an ICD-10 diagnosis of a psychotic disorder and who had been hospitalized for less than six months during the previous year., Results: People with psychotic disorders had high levels of use of health services, both in absolute terms and relative to people with nonpsychotic disorders. Those with psychotic disorders were estimated to have an average of one contact with health services per week. Use of psychiatric inpatient services was associated with parenthood, higher symptom levels, recent attempts at suicide or self-harm, personal disability, medication status, and frequency of alcohol consumption. Services provided by general practitioners (family physicians) were more likely to be obtained by older people, women, people with greater availability of friends, those with fewer negative symptoms, and those whose service needs were unmet by other sources. People who were high users of health services also reported having more contact with a range of non-health agencies., Conclusions: The predictors of service use accounted for small proportions of the variance in overall use of health services. The role of general practitioners in providing and monitoring treatment programs and other psychosocial interventions needs to be acknowledged and enhanced.

Objective: This commentary reviews current expenditure on psychosis in Australia, identifies discretionary expenditure that could be used more efficiently, discusses the factors influencing resource allocation and intervention selection decisions, and suggests priorities for change., Method: Cost-of-illness findings from the Low Prevalence Disorders Study (LPDS), and related service use and psychosocial data, are used to highlight patterns of expenditure on psychosis and potential resource allocation issues. Arguments are also presented suggesting that mental health resource allocation in Australia should be informed primarily by treatment efficiency, equity and humanitarian considerations, not differences in the global burden of disease. However, our evidence-base about the effectiveness and costs associated with individual treatments, programmes, and organizational structures is also shown to be limited., Conclusions: The patterns of service use and expenditure on psychosis suggest certain imbalances, including an over-reliance on hospitalization, low levels of supported community accommodation, and inadequate provision of evidence-based psychosocial treatments, rehabilitation and supported employment programmes. We need to identify and develop efficient interventions and programmes, re-orientate our services to better utilize those interventions, increase community awareness, improve monitoring of outcomes and costs, and undertake timely evaluations at multiple levels, from the individual to the societal perspective.

Objective: To estimate the costs associated with the treatment and care of persons with psychosis in Australia based on data from the Low Prevalence Disorders Study (LPDS), and to identify areas where there is potential for more efficient use of existing health care resources., Method: The LPDS was a one-month census-based survey of people with psychotic disorders in contact with mental health services, which was conducted in four metropolitan regions in 1997-1998. Mental health and service utilization data from 980 interviews were used to estimate the economic costs associated with psychotic disorders. A prevalence-based, 'bottom-up' approach was adopted to calculate the government and societal costs associated with psychosis, including treatment and non-treatment related costs., Results: Annual societal costs for the average patient with psychosis are of the order of 46,200 Australian dollars , comprising 27,500 Australian dollars in lost productivity, 13,800 Australian dollars in inpatient mental health care costs and 4900 Australian dollars in other mental health and community services costs. Psychosis costs the Australian government at least 1.45 billion Australian dollars per annum, while societal costs are at least 2.25 billion Australian dollars per annum (including 1.44 billion Australian dollars for schizophrenia). We also report relationships between societal costs and demographic factors, diagnosis, disability and participation in employment., Conclusions: Current expenditure on psychosis in Australia is probably inefficient. There may be substantial opportunity costs in not delivering effective treatments in sufficient volume to people with psychotic disorders, not intervening early, and not improving access to rehabilitation and supported accommodation.

Objective: To examine differences between samples of schizophrenia patients recruited from general practice and public mental health services., Method: Demographic, psychosocial, disability and 12-month service utilization data are reported from a multicentered survey of psychotic disorders and an associated study of schizophrenia in general practice. Patients with schizophrenia from three recruitment sources (in-patient, community services, general practice) were compared., Results: General practice patients had fewer symptoms, better functioning, lower service use, but comparable substance abuse, to patients from mental health services. They were generally similar to community mental health patients, with the exception of family support, premorbid work adjustment, negative symptoms and disability. Service contact models are also reported which demonstrate that general practitioners deal with schizophrenia patients across the range of illness severity and acuity., Conclusion: Recruitment source impacts in schizophrenia research need to be more carefully considered during sample selection and better accounted for in the interpretation of results.

Neuroimaging research has shown localised brain activation to different facial expressions. This, along with the finding that schizophrenia patients perform poorly in their recognition of negative emotions, has raised the suggestion that patients display an emotion specific impairment. We propose that this asymmetry in performance reflects task difficulty gradations, rather than aberrant processing in neural pathways subserving recognition of specific emotions. A neural network model is presented, which classifies facial expressions on the basis of measurements derived from human faces. After training, the network showed an accuracy pattern closely resembling that of healthy subjects. Lesioning of the network led to an overall decrease in the network's discriminant capacity, with the greatest accuracy decrease to fear, disgust and anger stimuli. This implies that the differential pattern of impairment in schizophrenia patients can be explained without having to postulate impairment of specific processing modules for negative emotion recognition.

Objective: This paper documents the establishment of the Schizophrenia Research Register of the Neuroscience Institute of Schizophrenia and Allied Disorders (NISAD). This register aims to provide a volunteer pool of people with a clinical diagnosis of schizophrenia who are willing to consider participating in research projects. This unique resource is accessible to the general scientific research community., Method: The Register, which operates as a standalone, computerized relational database, maintains demographic and clinical information about individuals with schizophrenia recruited through media campaigns, and general health and non-government support agencies. Preliminary data are reported on the first 400 people with schizophrenia who registered on the database, together with selected comparisons with data from the national Low Prevalence (psychotic) Disorders Study (LPDS)., Results: Individuals currently on the Register have a mean age of 38.74 years (SD = 11.41) and are predominantly Australian born (85.1%), which is consistent with data from the LPDS. However, the gender distribution is more balanced compared with the LPDS (53.8% vs 65.4% males) and proportionately more registrants are married or in de facto relationships (18.4% vs 10.8%). Registrants also tend to have lower current symptomatology and higher functioning relative to participants in the LPDS., Conclusions: The Register provides a unique and invaluable educational and research resource, as well as a complementary recruitment source for researchers who would otherwise rely on samples drawn primarily from mental health services.

Objective: To present a summary of quantitative scales relevant to schizophrenia prevention studies., Method: Fifteen scales were reviewed and summarised in terms of structure, domains assessed, previous use and psychometric properties. Instruments of symptom measurement, role functioning and global functioning were considered, along with multidimensional instruments and other scales of potential interest to research in schizophrenia prevention., Results and Conclusions: No scales of potential value in measuring premorbid risk for schizophrenia have been sufficiently tested for reliability and validity in the context of primary prevention of schizophrenia. The absence of a sufficiently sensitive and specific means for identifying those at high risk of schizophrenia before the onset of psychosis is a major barrier to valid measurement of the outcome of attempts at primary prevention. However, there have been advances in the development of instruments relevant to the goals of secondary and tertiary prevention. Most studies use instruments developed for patients with established psychoses and have applied them to early psychosis groups with some success, although possible 'floor' effects may confound measurement in the 'prodromal' period.

Objectives: To describe the hospital-treated prevalences for repeat deliberate self-poisoning (RDSP) and the demographic characteristics of the RDSP group, and to compare the RDSP and non-RDSP groups., Design: Prospective longitudinal cohort study, with a one- to four-year follow-up., Setting: The Hunter Area Toxicology Service (HATS), a regional toxicology treatment centre in New South Wales., Subjects: 1238 consecutive DSP patients referred to hospital, 1992-1994, with follow-up through 1995., Outcome Measures: Deliberate self-poisoning (DSP) admissions within one year (RDSP-1), within six months (RDSP-6m), and within 28 days (RDSP-28d) of any other DSP admission by the same patient; length of stay; demographic characteristics; and drugs ingested., Results: 175 patients (14.1%) repeated DSP during the study; 165 (13.3%) were classified as RDSP-1, giving a patient prevalence of hospitalisation in the range of 14.6 to 20.7 per 100,000 per year. Fifty-six RDSP-28d patients (33.9% of RDSP-1) accounted for 49.8% of the RDSP-1 admissions, and 123 RDSP-6m patients (74.5% of RDSP-1) accounted for 83.5% of RDSP-1 admissions. For RDSP-1, the male:female ratio was 1:1.9, with 35.7% unemployed, 29.1% pensioners and 15.8% married or in de facto relationships. RDSP-1 patients had a shorter length of stay (3 h), which was not clinically important. RDSP was more likely for the 25-34 years age group (odds ratio [OR], 2.24; 95% confidence interval [CI], 1.17-4.29) and the 35-44 years age group (OR, 2.12; 95% CI, 1.02-4.39) than the 10-18 years group, and more likely for women than men (OR, 1.69; 95% CI, 1.17-2.46). Being married/de facto reduced the risk for repetition (OR, 0.55; 95% CI, 0.31-0.96) compared with being single. Medications indicated for psychiatric illness were most commonly used for DSP., Conclusions: Many patients who repeat DSP do so after a very brief interval and account for a disproportionate number of hospitalisations. Availability of psychiatric medications for DSP patients is a possible area of intervention.

The long-term stability of ego defenses was examined in a group of 68 patients with major depression being treated in a rural private psychiatric practice. Current symptomatology and dispositional characteristics, including defense style (40-item Defense Style Questionnaire), were assessed pretreatment and at approximately 6 months and 2 years after treatment commenced. Age- and gender-matched comparison groups were also selected from two community-based studies that utilized similar instruments and time periods. The major depression group reported significantly lower usage of mature defenses initially, but with recovery they moved progressively toward the range of mature defenses displayed by the nonpatient comparison group. Neurotic defenses were relatively stable throughout the study, as were immature defenses during the first 6 months. Comparisons between patients who discontinued treatment (N = 24) and those who remained in treatment (N = 33) revealed similar rates of symptom reduction; however, the latter group reported continuing reductions in their use of immature defenses, to a level below that of the nonpatient comparison group.

Boys with Attention Deficit Hyperactivity Disorder (ADHD, N = 50), Specific Learning Disorder (LD, N = 45), combined Specific Learning Disorder and ADHD (LD/ADHD, N = 25), and controls (N = 51) completed effortful and automatic information processing tasks based on Treisman and Gelade's (1980) "information integration theory". ADHD and LD/ADHD subjects did not differ from controls at baseline or under feedback and reward conditions, suggesting that they were investing similar levels of mental effort in the tasks. The LD group had a superior performance in the effortful task and an inferior performance in the automatic task compared with the other groups at baseline. The data suggest a potential method of distinguishing primary LD from learning difficulties that occur secondary to ADHD.

This report describes part of a series of experiments, conducted within the framework of feature integration theory, to determine whether patients with schizophrenia show deficits in preattentive processing. Thirty subjects with a DSM-III-R diagnosis of schizophrenia and 30 age-, gender-, and education-matched normal control subjects completed two computerized experimental tasks, a visual search task assessing the frequency of illusory conjunctions (i.e. false perceptions) under conditions of divided attention (Experiment 3) and a task which examined the effects of perceptual grouping on illusory conjunctions (Experiment 4). We also assessed current symptomatology and its relationship to task performance. Contrary to our hypotheses, schizophrenia subjects did not show higher rates of illusory conjunctions, and the influence of perceptual grouping on the frequency of illusory conjunctions was similar for schizophrenia and control subjects. Nonetheless, specific predictions from feature integration theory about the impact of different target types (Experiment 3) and perceptual groups (Experiment 4) on the likelihood of forming an illusory conjunction were strongly supported, thereby confirming the integrity of the experimental procedures. Overall, these studies revealed no firm evidence that schizophrenia is associated with a preattentive abnormality in visual search using stimuli that differ on the basis of physical characteristics.

To help determine whether patients with schizophrenia show deficits in the stimulus-based aspects of preattentive processing, we undertook a series of experiments within the framework of feature integration theory. Thirty subjects with a DSM-III-R diagnosis of schizophrenia and 30 age-, gender-, and education-matched normal control subjects completed two computerized experimental tasks, a visual search task assessing parallel and serial information processing (Experiment 1) and a task which examined the effects of perceptual grouping on visual search strategies (Experiment 2). We also assessed current symptomatology and its relationship to task performance. While the schizophrenia subjects had longer reaction times in Experiment 1, their overall pattern of performance across both experimental tasks was similar to that of the control subjects, and generally unrelated to current symptomatology. Predictions from feature integration theory about the impact of varying display size (Experiment 1) and number of perceptual groups (Experiment 2) on the detection of feature and conjunction targets were strongly supported. This study revealed no firm evidence that schizophrenia is associated with a preattentive abnormality in visual search using stimuli that differ on the basis of physical characteristics. While subject and task characteristics may partially account for differences between this and previous studies, it is more likely that preattentive processing abnormalities in schizophrenia may occur only under conditions involving selected 'top-down' factors such as context and meaning.

Objective: To investigate how many people with schizophrenia are being treated by general practitioners (GPs) and what the associations are between GP characteristics and the number of patients with schizophrenia in their practice., Design and Setting: Pilot study by postal survey of all GPs in the Hunter/Taree region., Participants: 349 of 495 GPs (70.5%) replied to the survey--245 urban GPs and 104 rural GPs from the Hunter/Taree region of New South Wales., Main Outcome Measures: GP estimates of the number of patients with schizophrenia currently being treated and by whom., Results: Three-quarters of the GPs in the region were treating patients with schizophrenia, proportionately more in rural areas (87.5%) than in urban areas (70.2%). The typical GP was treating three patients with schizophrenia, two conjointly with specialist services and one without specialist support. It was estimated that the GP-treated prevalence for schizophrenia is 35.5 per 10,000 adults., Conclusion: Although individual GPs treat a small number of patients with schizophrenia, collectively they treat most of the patients with this disorder. Because schizophrenia has such a high burden of illness for the patient and the community, we need to find suitable mechanisms for evaluating and enhancing the treatment of schizophrenia in general practice.

Objective: We sought to identify the psychosocial characteristics of high earthquake exposure subjects that were associated with the development of post-disaster morbidity and with recovery., Method: Data reported are from 515 participants in a longitudinal study of the psychosocial effects of the 1989 Newcastle (Australia) earthquake. Subjects were allocated to three subgroups (low morbidity; recovered; and persistent morbidity) on the basis of their Impact of Event Scale scores across the four phases of the study. Differences between these subgroups were examined on a broad range of variables., Results: Several background, dispositional, coping style and exposure-related factors characterised those who developed psychological morbidity, only a small subset of which differentiated between those who recovered and those with persistent morbidity., Conclusions: Post-earthquake morbidity persists longer in those who are older, have a history of emotional problems, have higher neuroticism, use more neurotic defenses, and report higher levels of post-disaster life events.

A structured interview and standardized rating scales were used to assess a sample of 194 outpatients with schizophrenia in a regional Australian mental health service for substance use, abuse, and dependence. Case manager assessments and urine drug screens were also used to determine substance use. Additional measurements included demographic information, history of criminal charges, symptom self-reports, personal hopefulness, and social support. The sample was predominantly male and showed relative instability in accommodations, and almost half had a history of criminal offenses, most frequently drug or alcohol related. The 6-month and lifetime prevalence of substance abuse or dependence was 26.8 and 59.8 percent, respectively, with alcohol, cannabis, and amphetamines being the most commonly abused substances. Current users of alcohol comprised 77.3 percent and current users of other nonprescribed substances (excluding tobacco and caffeine) comprised 29.9 percent of the sample. Rates of tobacco and caffeine consumption were high. There was a moderate degree of concordance between case manager determinations of a substance-use problem and research diagnoses. Subjects with current or lifetime diagnoses of substance abuse/dependence were predominantly young, single males with higher rates of criminal charges; however, there was no evidence of increased rates of suicide attempts, hospital admissions, or daily doses of antipsychotic drugs in these groups compared with subjects with no past or current diagnosis of substance abuse or dependence. Subjects with a current diagnosis of substance use were younger at first treatment and currently more symptomatic than those with no past or current substance use diagnosis. The picture emerging from this study replicates the high rate of substance abuse in persons with schizophrenia reported in North American studies but differs from the latter in finding a slightly different pattern of substances abused (i.e., absence of cocaine), reflecting relative differences in the availability of certain drugs.

Objective: This study evaluated the 6-month outcome of patients referred by their general practitioner (GP) to a consultation-liaison (C-L) psychiatry service provided to eight group general practices., Method: Over a 12-month period, there were 307 referrals to the C-L psychiatry service of whom 86 consented to take part in an outcome study. Two different control groups were examined comprising patients seen by the same GPs but not referred to the C-L service, who were matched with the C-L referrals on the basis of either demographic characteristics (n = 86) or initial symptomatology (n = 59). Clinical interviews were conducted at recruitment to the outcome study using the Composite International Diagnostic Interview (CIDI), while postal questionnaires were used at both the initial and 6-month assessments., Results: Data reported include DSM-III-R clinical audit and CIDI diagnoses, changes in current symptomatology (SCL-90-R) and changes in global ratings of physical health, emotional health, social relationships and ability to perform everyday duties. Consultation-liaison referrals without symptom-matched controls (n = 27), being patients with higher levels of symptoms initially, were more likely to be referred to other psychiatric services for treatment. They also showed more marked improvement over time on the selected outcome measures. However, there were no significant differences in the patterns of change over time between symptom-matched C-L referrals and their non-referred controls., Conclusions: The findings from the 6-month outcome study raise doubts about the overall benefit of the current C-L service relative to usual GP care. Improving the quality of psychiatric care in general practice is likely to require a range of interrelated strategies, including C-L psychiatry services, GP education and well-functioning links with public mental health services.

The impact of a community-based consultation-liaison (C-L) psychiatry service on family physicians' levels of psychiatric knowledge, diagnostic and treatment confidence, and patterns of referral to mental health care agencies was evaluated over a 12-month period. The physicians with long-term access to the C-L service had higher levels of psychiatric knowledge than those with short-term or no access. However, there was no evidence that the C-L service produced changes in the physicians' levels of clinical confidence, referral likelihood, or psychiatric knowledge during the evaluation period. Significant predictors of psychiatric knowledge were age (younger) and gender (women). The participating physicians were highly satisfied with the service and preferred it over other possible referral agencies. However, community C-L services in family practice appear to have a limited role in the provision of psychiatric care and are not an efficient way for improving family physicians' levels of psychiatric knowledge or altering their practices. The appropriate role of community C-L psychiatry may be as one component of a comprehensive service-delivery strategy integrated within ongoing, formal family-physician educational programs.

This paper summarises the major findings from the Quake Impact Study (QIS), a four-phase longitudinal project that was conducted in the aftermath of the 1989 Newcastle (Australia) earthquake. A total of 3,484 subjects participated in at least one component of the QIS, comprising a stratified sample of 3,007 drawn from community electoral rolls and 477 from specially targeted supplementary samples (the injured, the displaced, the owners of damaged businesses, and the helpers). Subjects' initial earthquake experiences were rated in terms of weighted indices of exposure to threat and disruption. Psychological morbidity was measured at each phase using the General Health Questionnaire (GHQ-12) and the Impact of Event Scale (IES). Selected findings and key conclusions are presented for each of six areas of investigation: service utilisation during the first 6 months post-disaster; patterns of earthquake experience and short-term (6-month) psychosocial outcome; earthquake exposure and medium term (2-year) psychosocial outcome; vulnerability factors and medium-term psychosocial outcome; specific community groups at increased risk (e.g., the elderly and immigrants from non-English-speaking backgrounds); the effects of stress debriefing for helpers. Threshold morbidity (i.e., likely caseness) rates are also presented for a broad range of subgroups. In addition to presenting an overview of the QIS, this paper synthesises the major findings and discusses their implications for future disaster management and research from a mental health perspective.

This article provides practical guidelines for general practitioners in treating schizophrenia. Specific areas include pharmacological treatment, supportive therapy, depression and suicide, alcohol and drug abuse, sexuality, and physical health.

Objective: This paper describes the characteristics of 303 consecutive referrals, over a 12-month period, to a consultation-liaison (C-L) psychiatry service provided to eight group general practices in Newcastle, Australia., Method: A purpose designed service audit form was used throughout the evaluation period to collect information about demographic characteristics, reasons for referral, service contacts, psychiatric diagnoses and clinical management. In addition, patients were invited to participate in a separate, prospective outcome evaluation study, which involved structured interviews and questionnaires., Results: The most common reasons for referral were: depression (33%); anxiety (12%); diagnostic assessment (9%); and impaired relationships (8%). The most common psychiatric diagnoses were: mood disorders (29%); mild, transient conditions (29%); anxiety (14%); and substance abuse disorders (12%). Following the psychiatric consultation(s), GPs were actively involved in patients' treatment in 53% of cases. However, there was a higher than expected rate of referral (44%) to another mental health agency. Selected comparisons are also reported between patients referred to the C-L service (n = 303) and a sample of non-referred GP attenders (n = 535)., Conclusions: As expected, the diagnostic profiles of patients attending the C-L service differed in several respects from those using similar services in general hospitals. There were comparatively low rates of organic brain syndromes, suicide risk evaluations, and problems of differential diagnosis of somatic symptoms. Greater emphasis needs to be placed on more formal psychiatric education for GPs, on ways of screening out from the referral process those patients with mild, transient conditions who do not require specialist expertise, and on the development of strategies to help GPs manage such conditions.

In light of the emphasis on community care for schizophrenia and the increasing role likely to be played by general practitioners, this paper describes some of the general principles involved in the treatment of this disorder and provides a set of practical guidelines to assist general practitioners.

Background: This paper examines the contributions of dispositional and non-dispositional factors to post-disaster psychological morbidity. Data reported are from the 845 participants in the longitudinal component of the Quake Impact Study., Methods: The phase 1 survey was used to construct dimensional indices of threat and disruption exposure. Subsequently, a range of dispositional characteristics were measured, including neuroticism, personal hopefulness and defence style. The main morbidity measures were the General Health Questionnaire (GHQ-12) and Impact of Event Scale (IES)., Results: Dispositional characteristics were the best predictors of psychological morbidity throughout the 2 years post-disaster, contributing substantially more to the variance in morbidity (12-39%) than did initial exposure (5-12%), but the extent of their contribution was greater for general (GHQ-12) than for post-traumatic (IES) morbidity. Among the non-dispositional factors, avoidance coping contributed equally to general and post-traumatic morbidity (pr = 0.24). Life events since the earthquake (pr = 0.18), poor social relationships (pr = -0.25) and ongoing earthquake-related disruptions (pr = 0.22) also contributed to general morbidity, while only the latter contributed significantly to post-traumatic morbidity (pr = 0.15)., Conclusions: Medium-term post-earthquake morbidity appears to be a function of multiple factors whose contributions vary depending on the type of morbidity experienced and include trait vulnerability, the nature and degree of initial exposure, avoidance coping and the nature and severity of subsequent events.

Background: A sample of 1089 Australian adults was selected for the longitudinal component of the Quake Impact Study, a 2-year, four-phase investigation of the psychosocial effects of the 1989 Newcastle earthquake. Of these, 845 (78%) completed a survey 6 months post-disaster as well as one or more of the three follow-up surveys., Methods: The phase 1 survey was used to construct dimensional indices of self-reported exposure to threat the disruption and also to classify subjects by their membership of five 'at risk' groups (the injured; the displaced; owners of damaged small businesses; helpers in threat and non-threat situations). Psychological morbidity was assessed at each phase using the 12-item General Health Questionnaire (GHQ-12) and the Impact of Event Scale (IES)., Results: Psychological morbidity declined over time but tended to stabilize at about 12 months post-disaster for general morbidity (GHQ-12) and at about 18 months for trauma-related (IES) morbidity. Initial exposure to threat and/or disruption were significant predictors of psychological morbidity throughout the study and had superior predictive power to membership of the targeted 'at risk' groups. The degree of ongoing disruption and other life events since the earthquake were also significant predictors of morbidity. The injured reported the highest levels of distress, but there was a relative absence of morbidity among the helpers., Conclusions: Future disaster research should carefully assess the threat and disruption experiences of the survivors at the time of the event and monitor ongoing disruptions in the aftermath in order to target interventions more effectively.

Mental health counsellors could provide one component of an integrated solution to the structural problems now inherent in the primary care of patients with mental health problems. Further training of general practitioners in interview and counselling skills is also essential.

This paper describes the construction, refinement and implementation of a self-administered measure of personal hopefulness, the Hunter Opinions and Personal Expectations Scale (HOPES). Initial state and trait versions of the HOPES instrument were utilized in three separate studies, comprising a medical student sample (N = 211), an adolescent male sample (N = 280) and a psychiatric hospital staff sample (N = 318). A revised 20-item, two factor, trait version of the scale was then utilized in a prospective, longitudinal investigation (N = 753) of the psychosocial sequelae of the earthquake which struck Newcastle (Australia) in December, 1989. Data from all four studies provide strong support for the HOPES instrument's construct, concurrent and predictive validity. Global personal hopefulness (GPH) was shown to be an enduring characteristic of individuals, with a test-retest correlation of r = + 0.71 (over 64 weeks). The association between GPH and trait anxiety (r = -0.64) raised the possibility of redefining anxiety as hope under threat. The hope subscale (HS) and the despair subscale (DS) were moderately negatively correlated (r = -0.32), suggesting that hope and despair are not simply polar opposites. There were no gender differences in GPH scores, however, there were relatively clear age effects, with those aged 70 years and over reporting the lowest levels of personal hopefulness. GPH was negatively correlated with post-earthquake scores on the General Health Questionnaire (r = -0.33), the Impact of Event Scale (r = -0.33), the Beck Depression Inventory (r = -0.54) and the global symptom index from the SCL-90-R (r = -0.43). Overall, the contribution made by personal hopefulness to post-earthquake morbidity was equal to the contributions made by initial exposure to disruption and threat experiences.

Objective: Efforts to improve the psychiatric competence of the general medical workforce must include an appraisal of how psychiatry is taught in medical schools. As a contribution to this appraisal a description is given of psychiatric education in the innovative undergraduate medical curriculum at the University of Newcastle., Method: An outline of the features which characterise medical education at Newcastle is provided and the way in which the teaching of psychiatry is organised within this framework is presented., Results: The characteristics of the Newcastle undergraduate program in psychiatry include its integration with teaching in other clinical and basic science disciplines, continuity throughout the entire five years of the course, and the emphasis on skills acquisition and their assessment., Conclusions: The relative merits and disadvantages of the Newcastle approach to undergraduate psychiatry education are presented and the problem of assessing the effectiveness of this approach by outcomes measurement, particularly of integrated competencies and their application in general medical settings, is discussed.

Stress debriefing has been used extensively following traumatic events; however, there is little evidence of its effectiveness. This paper reports the effects of stress debriefing on the rate of recovery of 195 helpers (e.g., emergency service personnel and disaster workers) following an earthquake in Newcastle, Australia (62 debriefed helpers and 133 who were not debriefed). Post-trauma stress reactions (Impact of Event Scale) and general psychological morbidity (General Health Questionnaire: GHQ-12) were assessed on four occasions over the first 2 years postearthquake. There was no evidence of an improved rate of recovery among those helpers who were debriefed, even when level of exposure and helping-related stress were taken into account. More rigorous investigation of the effectiveness of stress debriefing and its role in posttrauma recovery is urgently required.

The psychosocial effects of the 1989 Newcastle earthquake on 250 immigrants from non-English-speaking backgrounds (NESB) were compared with a matched sample of 250 Australian-born subjects. The NESB subjects had higher levels of both general (General Health Questionnaire-12) and event-related (Impact of Event Scale) psychological morbidity. Furthermore, NESB females had the highest levels of distress, particularly those who were older on arrival in Australia and those who experienced high levels of disruption. The results suggest that NESB immigrants, particularly women, appear to be more at risk for developing psychological distress following a natural disaster. However, level of exposure and an avoidance coping style contributed more substantially to psychological distress than ethnicity.

A stratified random sample of 3007 Australian adults completed a screening questionnaire 6 months after the 1989 Newcastle earthquake. Information was obtained on initial earthquake experiences and reactions, use of specific services, social support, coping strategies and psychological morbidity. This questionnaire was the first phase of the Quake Impact Study, a longitudinal project investigating the psychosocial impact of the earthquake. Two weighted indices of exposure were developed: a threat index, which measured exposure to injury or the possibility of injury; and a disruption index, which measured experiences of property damage, displacement and other losses. Levels of exposure to threat and disruption events were significant predictors of morbidity on both the General Health Questionnaire and Impact of Event Scale, as were coping style and gender. Effects of exposure to threat and disruption were largely additive, with higher exposure being associated with greater use of support services, higher perceived stressfulness and more severe psychological morbidity. Use of avoidance as a coping strategy, female gender, lower social support and being older were also associated with higher post-disaster psychological distress. It was estimated that 14.8% of the population was exposed to high levels of threat or disruption, of whom approximately 25% experienced moderate to severe psychological distress as a direct result of the disaster. It was further estimated that 18.3% of those exposed to high levels of threat were at risk of developing post-traumatic stress disorder, representing approximately 2% of the city's adult population.

The aim of the study was to establish the current and desired levels of staffing and funding of the 52 consultation-liaison (C-L) psychiatry training units in Australian and New Zealand general hospitals. Administration of a questionnaire and follow-up verification provided data on referral rates, existing and preferred staffing levels, and staff workloads. The referral rates and staffing levels in most cases fall below those quoted for Europe and the USA, and those considered optimal by the respondents. This, together with the large variation in referral rates and workload, has implications for the type of clinical activity conducted and quality of the training experience in different units.

A screening questionnaire was distributed to 5,000 adult members of the community six months after the 1989 Newcastle earthquake, with a response rate of 63 per cent (n = 3,007). The mean age of respondents was 46.7 years and 58 per cent were female. Subjects' earthquake experiences were rated in terms of weighted indices of exposure to threat and disruption. Psychological morbidity was measured using the General Health Questionnaire and the Impact of Event Scale. Subjects were asked to indicate which of a range of general and disaster-related support services they had used in dealing with the stressful effects of the earthquake. It was estimated that 21.3 per cent of the adult population used general and/or disaster-related support services. Users of these services reported greater exposure to threat and/or disruption and had higher levels of psychological distress than nonusers. However, a high level of use of general services and reliance on medical services were related more to psychological morbidity than degree of exposure to earthquake-related events. Overall, the Newcastle community's needs for assistance in the aftermath of the earthquake were effectively absorbed by the existing support services and the resources marshalled to supplement those services. Individuals and organisations mobilised following natural disasters need to be strengthened by enhancing the capacity of support service workers to identify and manage psychological distress in their clients.

Objective: To improve the quality and accessibility of psychiatric service in the primary care setting., Design: Under the liaison-attachment model, a senior psychiatry trainee provided psychiatric consultations part-time in general practice over an 18-month period. Patients regarded by the participating doctors as having significant psychiatric problems were referred to the trainee for consultation., Setting: Four group general practices, involving 18 doctors, took part in the scheme., Participants: During the study 172 patients with a wide spectrum of diagnoses were assessed. Near the end of the 18-month period the participating general practitioners provided their evaluations of the scheme., Intervention: In almost all cases standard treatment was provided in the primary care setting and administered by either a general practitioner, the trainee or both working collaboratively together., Outcome Measures: The general practitioners evaluated the results of the consultations and the effect of the service on their referral patterns. They also rated the overall impact of the scheme on their own knowledge and skills, the quality of care, and its accessibility., Results: The quality of outcome, if known, was regarded as satisfactory in 88% of cases. The reported frequency of referrals to psychiatrists in private practice dropped significantly. The participating doctors perceived improvements in their own abilities to deal with psychiatric problems and regarded the quality and accessibility of psychiatric care to be enhanced by the scheme., Conclusions: The psychiatric liaison-attachment model, developed in Britain, is applicable and effective in the Australian primary care setting.

The literature describing symptomatic recovery in schizophrenic psychosis is reviewed. The dimensional and categorical models which have been used in this context are examined separately, and the phenomena of postpsychotic depression and style of recovery are also discussed. A model is then suggested in which the process of recovery is related to five dimensions of psychopathology. Such a model may be of use in efficiently describing the short-term course of psychosis in which symptom patterns or states, having relevance for clinical practice and research, could be defined.
