The iTreAD project: a study protocol for a randomised controlled clinical trial of online treatment and social networking for binge drinking and depression in young people.

BACKGROUND: Depression and binge drinking behaviours are common clinical problems, which cause substantial functional, economic and health impacts. These conditions peak in young adulthood, and commonly co-occur. Comorbid depression and binge drinking are undertreated in young people, who are reluctant to seek help via traditional pathways to care. The iTreAD project (internet Treatment for Alcohol and Depression) aims to provide and evaluate internet-delivered monitoring and treatment programs for young people with depression and binge drinking concerns. METHODS: Three hundred sixty nine participants will be recruited to the trial, and will be aged 18-30 years will be eligible for the study if they report current symptoms of depression (score 5 or more on the depression subscale of the Depression Anxiety Stress Scale) and concurrent binge drinking practices (5 or more standard drinks at least twice in the prior month). Following screening and online baseline assessment, participants are randomised to: (a) online monthly self-assessments, (b) online monthly self-assessments + 12-months of access to a 4 week online automated cognitive behaviour therapy program for binge drinking and depression (DEAL); or (c) online monthly assessment + DEAL + 12-months of access to a social networking site (Breathing Space). Independent, blind follow-up assessments occur at 26, 39, 52 and 64-weeks post-baseline. DISCUSSION: The iTreAD project is the first randomised controlled trial combining online cognitive behaviour therapy, social networking and online monitoring for young people reporting concerns with depression and binge drinking. These treatments represent low-cost, wide-reach youth-appropriate treatment, which will have significantly public health implications for service design, delivery and health policy for this important age group.

Attitudes and perceptions towards substances among people with mental disorders: a systematic review.

OBJECTIVE: To develop effective interventions for people with coexisting mental disorders (MD) and substance use, it may be beneficial to understand their attitudes and perceptions of substances. METHOD: A systematic literature search regarding attitudes and perceptions towards tobacco, alcohol or cannabis among people with MD was conducted. Studies' methodological quality was assessed using the Newcastle-Ottawa Scale. RESULTS: Twenty-one papers were included in the review and found to have generally low methodological quality. Papers investigated reasons for substance use, substance use expectancies, substances' perceived effects and reasons for quitting. People with psychotic disorders reported using substances primarily for relaxation and pleasure. Among people with mood disorders, alcohol was used primarily for social motives and tobacco for negative affect reduction. CONCLUSION: For substance use interventions among people with MD to be more effective, it may be necessary to tailor interventions specifically for this population and customize by substance type. Gaps in the literature regarding attitudes and perceptions towards substance use among people with MD were identified, which future research should aim to address. These include designing and conducting methodologically rigorous research, investigating perceived harmfulness and knowledge of substances, and broadening recruitment of participants to include people with MD other than psychosis.

Does living in remote Australia lessen the impact of hardship on psychological distress?

AIMS: Rural and remote regions tend to be characterised by poorer socioeconomic conditions than urban areas, yet findings regarding differences in mental health between rural and urban areas have been inconsistent. This suggests that other features of these areas may reduce the impact of hardship on mental health. Little research has explored the relationship of financial hardship or deprivation with mental health across geographical areas. METHODS: Data were analysed from a large longitudinal Australian study of the mental health of individuals living in regional and remote communities. Financial hardship was measured using items from previous Australian national population research, along with measures of psychological distress (Kessler-10), social networks/support and community characteristics/locality, including rurality/remoteness (inner regional; outer regional; remote/very remote). Multilevel logistic regression modelling was used to examine the relationship between hardship, locality and distress. Supplementary analysis was undertaken using Australian Household, Income and Labour Dynamics in Australia (HILDA) Survey data. RESULTS: 2161 respondents from the Australian Rural Mental Health Study (1879 households) completed a baseline survey with 26% from remote or very remote regions. A significant association was detected between the number of hardship items and psychological distress in regional areas. Living in a remote location was associated with a lower number of hardships, lower risk of any hardship and lower risk of reporting three of the seven individual hardship items. Increasing hardship was associated with no change in distress for those living in remote areas. Respondents from remote areas were more likely to report seeking help from welfare organisations than regional residents. Findings were confirmed with sensitivity tests, including replication with HILDA data, the use of alternative measures of socioeconomic circumstances and the application of different analytic methods. CONCLUSIONS: Using a conventional and nationally used measure of financial hardship, people residing in the most remote regions reported fewer hardships than other rural residents. In contrast to other rural residents, and national population data, there was no association between such hardship and mental health among residents in remote areas. The findings suggest the need to reconsider the experience of financial hardship across localities and possible protective factors within remote regions that may mitigate the psychological impact of such hardship.

The spectrum of mucin-producing adenocarcinoma of the pancreas.

The clinical distinction between cystic and mucinous carcinomas of the pancreas has been poorly defined. Therefore we sought to stratify the entity known as pancreatic mucinous adenocarcinoma based on pathologic and clinical criteria. Clinical data and pathology specimens were reviewed for patients (n = 40) who had been diagnosed as having mucin-producing pancreatic adenocarcinoma and had undergone either resection or intraoperative biopsy of their pancreatic tumor during a 40-year period at the UCLA Medical Center. Based on histologic criteria, three distinct classes of pancreatic adenocarcinoma were identified: mucinous noncystic (colloid) adenocarcinoma (group I), mucinous cystadenocarcinoma (group II), and ductal adenocarcinoma (group III). Based on clinical behavior, groups I and III were indistinguishable. Compared to patients from groups I and III, those from group II were younger, more likely to be female, and had a better prognosis. Among mucin-producing adenocarcinomas of the pancreas, mucinous noncystic adenocarcinoma and ductal adenocarcinoma share similar clinical features, whereas true cystic lesions represent a distinct clinical entity.

Patterns of current and lifetime substance use in schizophrenia.

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.

Randomized controlled trial of brief cognitive-behavioural interventions among regular users of amphetamine.

AIMS: To identify whether brief cognitive-behavioural interventions are feasible among regular users of amphetamine, to assess the effectiveness of intervention overall and to pilot two- and four-session interventions. DESIGN: Subjects were assigned randomly to individually receive a cognitive-behavioural intervention (n = 32) of either two or four sessions' duration or a self-help booklet (control condition; n = 32). SETTING: Subjects were volunteers recruited from needle exchange schemes and treatment centres in Newcastle, Australia. PARTICIPANTS: Regular (at least monthly) users of amphetamine were recruited. INTERVENTION: Either four sessions of cognitive-behaviour therapy, consisting of a motivational interview and skills training in avoidance of high-risk situations, coping with craving and relapse prevention, or two sessions consisting of a motivational interview and discussion of skills. MEASUREMENTS: The Opiate Treatment Index was the main measure at pre-treatment and 6-month follow-up. FINDINGS: There was a significant reduction in amphetamine use among the sample as a whole, with inconclusive differences between intervention subgroups. There was a moderate overall intervention effect, with the intervention group reporting over twice the reduction in daily amphetamine use as the control group. Significantly more people in the cognitive-behavioural intervention condition abstained from amphetamine at 6-month follow-up compared to the control condition. CONCLUSION: Brief cognitive-behavioural interventions appear feasible among regular users of amphetamine. A larger randomised controlled trial of the effectiveness of such interventions appears warranted.

Preattentive visual search and perceptual grouping in schizophrenia.

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.

Illusory conjunctions and perceptual grouping in a visual search task in schizophrenia.

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.

Grief reactions of parental couples: congenital handicap and cot death.

This study addresses the grief reaction of parental couples to congenital handicap and cot death. It was thought that the two groups would be similar in their response patterns and follow the sequential stages that are described in the literature on grief and bereavement, but that they would differ in the intensity and duration of their grief. Results indicate that, in the short term, parents who have experienced a sudden infant death have higher levels of unresolved grief and that, overall, mothers experienced greater anxiety and depression than did fathers.

Rates of treatment of schizophrenia by general practitioners. A pilot study.

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.

Comparison of integrated and consultation-liaison models for providing mental health care in general practice in New South Wales, Australia.

Comparison of integrated and consultation-liaison models for providing mental health care in general practice in New South Wales, Australia The characteristics of a new service providing integrated mental health care in general practice are described and comparisons made with an earlier consultation-liaison (C-L) psychiatry service in general practice, including the range and severity of psychiatric problems, levels of general practitioner (GP) and psychiatrist involvement, and patterns of care. Clinical audit checklists were completed by two experienced mental health nurses for the first 100 patients referred to the service, which was conducted in conjunction with 8 general practices in the Port Stephens region of New South Wales, Australia. The mean age of the first 100 referrals was 38.05 years, 63.0% were female, and 55.0% were referred from GPs. Outcome measures included: referral information, patients' demographic and diagnostic characteristics, psychosocial functioning, psychotropic medication, management, and number of contacts with the mental health nurses. Relative to the earlier C-L psychiatry service in general practice, the integrated service treated a broader range of diagnostic groups with higher levels of disability. There were higher rates of mood (48.0%) and psychotic (20.0%) disorders and lower rates of adjustment (2.0%) disorders. One-third of patients were seen by an additional agency, other than the mental health nurses or GPs. Patients averaged 4.95 contacts with the mental health nurses, with marked variations according to diagnostic group. To date, the new service has been well received. It is highly accessible, acceptable to GPs and patients, caters for a broad range of psychopathology, including severe mental illness, and appears to be sufficiently versatile to be adaptable to a variety of treatment settings.

Confirmation that Child Behavior Checklist clinical scales discriminate juvenile mania from attention deficit hyperactivity disorder.

OBJECTIVE: To determine whether boys meeting diagnostic criteria for juvenile mania and attention deficit hyperactivity disorder (mania-ADHD) may be distinguished from boys with ADHD alone on a range of clinical and family variables. METHODOLOGY: Boys aged 9-13 years with mania-ADHD (n = 25), ADHD alone (n = 99), or no psychiatric diagnosis (n = 27) were compared on parent and teacher report Child Behavior Checklists (CBCL) and Conners Questionnaires, self-report CBCLs, patterns of comorbidity, intellectual functioning, and family variables. RESULTS: Mania-ADHD subjects had significantly higher mean ratings than ADHD only subjects on the parent CBCL for the Withdrawn, Thought Problems, Delinquent Behavior and Aggressive Behavior scales and significantly higher rates of comorbid depression, anxiety and psychotic symptoms. Other variables did not distinguish the mania-ADHD and ADHD only groups. CONCLUSIONS: These data confirm previous research indicating that the CBCL may be used to assist in the clinical identification of manic children.

Long-term changes in defense style among patients recovering from major depression.

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.

Recovery from post-earthquake psychological morbidity: who suffers and who recovers?

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.

The NISAD Schizophrenia Research Register: why do we need a database of schizophrenia volunteers?

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.

Effects of a natural disaster on immigrants and host population.

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.

Patterns of service utilisation following the 1989 Newcastle earthquake: findings from phase 1 of the Quake Impact Study.

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.

Australian children and the threat of nuclear war.

Seven hundred and one 10- to 13-year-old schoolchildren from 20 schools in the Hunter region of New South Wales were asked questions about the future. The questionnaire, which was in two main sections, commenced with general, open-ended questions about the children's expectations, hopes and wishes. It then moved to more specific questions which were designed to assess the children's current level of knowledge about nuclear war. In the unprompted section, 56% of the children mentioned war as one of their concerns, while 33% wrote specifically of nuclear war. In answer to specific questions, the majority (97%) of children reported being aware of the issues of nuclear armaments and nuclear war. Sixty-eight per cent of children considered that nuclear war will or might occur; 31% felt that this would be within their own lifetimes. Most of the children reported the mass media to be their source of information on these issues; very few had heard about them from family or friends. The results challenge a commonly expressed belief that children of this age are not aware of the nuclear arms situation. Awareness of this issue and its implications, which is coupled with a lack of opportunities for discussion, may be detrimental to the well-being of children.

Determining the effect that consultation-liaison psychiatry in primary care has on family physicians' psychiatric knowledge and practice.

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.

Consultation-liaison psychiatry in general practice.

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.
