Health professionals' recognition of co-occurring alcohol and depressive disorders in youth: a survey of Australian general practitioners, psychiatrists, psychologists and mental health nurses using case vignettes

Objective: To examine whether health professionals who commonly deal with mental disorder are able to identify co occurring alcohol misuse in young people presenting with depression. Method: Between September 2006 and January 2007, a survey examining beliefs regarding appropriate interventions for mental disorder in youth was sent to 1710 psychiatrists, 2000 general practitioners (GPs), 1628 mental health nurses, and 2000 psychologists in Australia. Participants within each professional group were randomly given one of four vignettes describing a young person with a DSM-IV mental disorder. Herein is reported data from the depression and depression with alcohol misuse vignettes. Results: A total of 305 psychiatrists, 258 GPs, 292 mental health nurses and 375 psychologists completed one of the depression vignettes. A diagnosis of mood disorder was identified by at least 83.8% of professionals, with no significant differences noted between professional groups. Rates of reported co-occurring substance use disorders were substantially lower, particularly among older professionals and psychologists. Conclusions: GPs, psychologists and mental health professionals do not readily identify co-occurring alcohol misuse in young people with depression. Given the substantially negative impact of co-occurring disorders, it is imperative that health-care professionals are appropriately trained to detect such disorders promptly, to ensure young people have access to effective, early intervention.

Caseload management, work-related stress and case manager self-efficacy among Victorian mental health case managers

Objective: In Australia and comparable countries, case management has become the dominant process by which public mental health services provide outpatient clinical services to people with severe mental illness. There is recognition that caseload size impacts on service provision and that management of caseloads is an important dimension of overall service management. There has been little empirical investigation, however, of caseload and its management. The present study was undertaken in the context of an industrial agreement in Victoria, Australia that required services to introduce standardized approaches to caseload management. The aims of the present study were therefore to (i) investigate caseload size and approaches to caseload management in Victoria's mental health services; and (ii) determine whether caseload size and/or approach to caseload management is associated with work-related stress or case manager self-efficacy among community mental health professionals employed in Victoria's mental health services. Method: A total of 188 case managers responded to an online cross-sectional survey with both purpose-developed items investigating methods of case allocation and caseload monitoring, and standard measures of work-related stress and case manager personal efficacy. Results: The mean caseload size was 20 per full-time case manager. Both work-related stress scores and case manager personal efficacy scores were broadly comparable with those reported in previous studies. Higher caseloads were associated with higher levels of work-related stress and lower levels of case manager personal efficacy. Active monitoring of caseload was associated with lower scores for work-related stress and higher scores for case manager personal efficacy, regardless of size of caseload. Although caseloads were most frequently monitored by the case manager, there was evidence that monitoring by a supervisor was more beneficial than self-monitoring. Conclusion: Routine monitoring of caseload, especially by a workplace supervisor, may be effective in reducing work-related stress and enhancing case manager personal efficacy.

Carers' hope, wellbeing and attitudes regarding recovery

Carers are important to the recovery of their relatives with serious mental disorder however, it is unclear whether they are aware of, or endorse recent conceptualisations of recovery. This study compared carers’ and mental health workers’ recovery attitudes, and undertook multivariate predictions of carers’ wellbeing, hopefulness and recovery attitudes. Participants were 82 Australian family members caring for a relative with psychosis. Carers’ average recovery attitudes were less optimistic than for previously surveyed staff. Carers’ recovery attitudes were predicted by perceptions that their relative’s negative symptoms were more severe. Hopefulness and wellbeing was predicted by more positive and less negative caregiving experiences. Hopefulness was also predicted by less frequent contacts with their affected relative, and unexpectedly, by perceptions of more severe psychotic symptoms. Carers’ wellbeing was further predicted by having a partner and having no lifetime history of a mental disorder. Hope and wellbeing are affected by everyday challenges and positive experiences of caregiving.

Reasons for substance use among people with mental disorders

Background: Comorbidity of mental disorders and substance use continues to be a major problem. To inform the development of more effective interventions for these co-existing disorders, this paper aimed to determine if there are clear variations in the reasons for tobacco, alcohol or cannabis use across people with different mental disorders. Methods: Data from five randomized controlled trials on co-existing disorders that measured reasons for tobacco, alcohol or cannabis use using the Drug Use Motives Questionnaire, Reasons for Smoking Questionnaire or via free response are reported and combined. Two studies involved participants with depression, two involved participants with a psychotic disorder and one involved participants with a range of mental disorders. A series of logistic regressions were conducted to examine differences in reasons for tobacco, alcohol or cannabis use and to compare these reasons between people with psychotic disorders or depression. Results: Participants had a mean age of 38 (SD=12) and just over half (60%) were male. Forty-six percent of participants had a psychotic disorder and 54% experienced depression. Data from 976 participants across the five studies were included in the analyses. Tobacco and alcohol were primarily used to cope, while cannabis was primarily used for pleasure. People with psychotic disorders were more likely than people with depression to use tobacco for coping, pleasure and illness motives. People with depression, in contrast, were more likely to use alcohol for these reasons and social reasons. Conclusions: It may be important to tailor interventions for co-existing mental disorders and substance use by substance type and type of mental disorder. For example, interventions might be improved by including alternative coping strategies to tobacco and/or alcohol use, by addressing the social role of alcohol and by helping people with mental disorders using cannabis to gain pleasure from their lives in other ways.

The public health challenges of mental health problems and associated difficulties

Mental health is a major global health issue. Neuropsychiatric conditions are the most significant cause of disability worldwide, and account for 14% of the global burden of disease. Depression in particular places a huge burden on society, with the Global Burden of Disease 2000 study listing it as the fourth leading cause of disease burden worldwide and the largest non-fatal disease burden. In Australia, mental disorders are startlingly common and related to significant disability. The 2007 National Survey of Mental Health and Wellbeing revealed that the lifetime prevalence of any mental disorder was 45%, and within the last 12 months 20% of Australians met criteria for a mental disorder. Many of the articles in this issue explore mental health issues in young people. Indeed, mental health issues account for a large proportion of the disease burden in young people. Across the globe, mental health disorders caused the greatest number of years lost to disability(YLDs) amongst young people aged 10 to 24 years (45% of total YLDs). Depression caused the highest number of disability-adjusted life-years (DALYs) across this age group, accounting for 8. 2% of DALYs alone.6 It is clear that mental health is a critical area of focus for researchers, practitioners, and policy makers.

Validating a screening tool for mental health and substance use risk in an Indigenous prison population

Introduction and Aims: The Indigenous Risk Impact Screen (IRIS) is a validated culturally appropriate and widely used tool in the community for assessing substance use and mental disorder. This research aimed to assess the utility of this tool in an Indigenous prison population. Design and Methods: The study used data collected from a cross-sectional study of mental health among indigenous inmates in Queensland custodial centres (n=395, 84% male). Participants were administered a modified version of the IRIS, and ICD-10 diagnoses of substance use, depressive and anxiety disorders obtained using the Composite International Diagnostic Interview (CIDI). The concurrent validity of the modified IRIS was assessed against those of the CIDI. Results: 312 people screened as high risk for a substance use disorder and 179 were high risk for mental problems. 73% of males and 88% of females were diagnosed with a mental disorder. The IRIS was an effective screener for substance use disorders, with high sensitivity (Se) of 94% and low specificity (Sp) of 33%. The screener was less effective in identifying depression (Se 82%, Sp 59%) and anxiety (Se 68%, Sp 60%). Discussion: The IRIS is the first culturally appropriate screening instrument to be validated for the risk of drug and alcohol and mental disorder among Indigenous adults in custody. Conclusions: This study demonstrated that the IRIS is a valid tool for screening of alcohol and drug use risk among an incarcerated Indigenous population. The IRIS could offer an opportunity to improve the identification, treatment and health outcomes for incarcerated Indigenous adults.

The institutional limits to, and possibility of, understanding young people diagnosed with 'mental disorders', within inclusive teacher-student relationships

A persistent pattern of exclusion of young people with ‘mental disorders’ from school systems, despite the best intentions of schools and teachers, has prompted a call for a more reflexive understanding of their behaviours. This thesis, by describing how institutionally recognised ways of understanding can result in otherwise avoidable moral collisions and exclusion, produces new insights into the nature and processes of understanding required to promote inclusion. These insights were produced through an intensive qualitative examination of a violent classroom episode, identifying key points in the interaction that could make the difference between misrecognition and recognition, turning exclusion into inclusion.

Gaming well: Links between videogames and flourishing mental health

This paper is a review of the state of play of research linking videogaming and flourishing, and explores the role of videogames and technology to improve mental health and well-being. Its purpose is to develop understandings about the positive intersection of gaming and well-being, to document evidence regarding links between videogames and positive mental health, and to provide guidelines for use by other researchers as they design and use tools and games to improve mental health and well-being. Using Huppert's (Huppert and So, 2013) proposition that to flourish is more than the absence of mental disorder but rather a combination of feeling good and functioning effectively, resulting in high levels of mental well-being, and Seligman's (Seligman, 2011) PERMA theory of well-being, the paper identifies strengths in existing games that generate positive affect, positive functioning, and positive social functioning, contributing to, and supporting mental health and well-being.

The DISC1 Pathway in the Genetic Etiology of Schizophrenia

Schizophrenia is a severe psychotic disorder affecting 0.5-1 % of the population. The disorder is characterized by hallucinations; delusions; disorganized behavior and speech; avolition; anhedonia; flattened affect and cognitive deficits. The etiology of the disorder is complex with evidence for multiple genes contributing to the onset of the disorder along with environmental factors. DISC1 is one of the most promising candidate genes for schizophrenia. It codes for a protein which takes part in numerous molecular interactions along several pathways. This network, termed as the DISC1 pathway, is evidently important for the development and maturation of the central nervous system from the embryo until young adulthood. Disruption at these pathways is thought to predispose schizophrenia. In the present study, we have studied the DISC1 pathway in the etiology of schizophrenia in the Finnish population. We have utilized large Finnish samples; the schizophrenia family sample where DISC1 was originally shown to associate with schizophrenia and the Northern Finland birth cohort 1966 (NFBC66). Several DISC1 binding partners displayed evidence for association in the family sample along with DISC1. Through a genome-wide linkage study, we found a significant linkage signal to a locus where a DISC1 binding partner NDE1 is located at the carriers of a certain DISC1 risk variant. In a follow-up study, genetic markers in NDE1 displayed significant evidence for association with schizophrenia. Further exploration of association between 11 genes of the DISC1 pathway and schizophrenia led to recognition of novel variants in NDEL1, PDE4B and PDE4D that significantly either increased or decreased the risk for schizophrenia. Further, we found evidence that DISC1 itself has a significant role in the human mental functioning even in the healthy population. Variants in DISC1 had a significant effect on anhedonia which is a trait present at everybody but is in its severe form one of the main symptoms of schizophrenia and correlates with the risk of developing the disorder. Further, utilizing genome-wide marker data, we recognized three genes; MIR620; CCDC141 and LCT; that are closely related to the DISC1 pathway but which effects on anhedonia were observable only at the individuals who carried these specific DISC1 variants. Our findings significantly add up to the previous evidence for the involvement of DISC1 and the DISC1 pathway in the etiology of schizophrenia and psychosis. Our results support the concept of a number of DISC1 pathway related genes contributing in the etiology of schizophrenia along with DISC1 and provide new candidates for the studies of schizophrenia. Our findings also significantly increase the importance of DISC1 itself as having a role in psychological functioning in the general population.

The molecular basis of Marinesco-Sjögren syndrome

Marinesco-Sjögren syndrome (MSS) is a rare autosomal recessive neurodegenerative disorder characterized by cerebellar ataxia due to cerebellar cortical atrophy, infantile- or childhood-onset bilateral cataracts, progressive myopathy, and mild to severe mental retardation. Additional features include hypergonadotropic hypogonadism, various skeletal abnormalities, short stature, and strabismus. The neuroradiologic hallmarks are hypoplasia of both the vermis and cerebellar hemispheres. The histopathologic findings include severe cerebellar atrophy and loss of Purkinje and granule cells. The common pathologic findings in muscle biopsy are variation in muscle fiber size, atrophic fibers, fatty replacement, and rimmed vacuole formation. The presence of marked cerebellar atrophy with myopathy distinguishes MSS from another rare syndrome, the congenital cataracts, facial dysmorphism, and neuropathy syndrome (CCFDN). Previously, work by others had resulted in the identification of an MSS locus on chromosome 5q31. A subtype of MSS with myoglobinuria and neuropathy had been linked to the CCFDN locus on chromosome 18qter, at which mutations in the CTDP1 gene had been identified. We confirmed linkage to the previously identified locus on chromosome 5q31 in two Finnish families with eight affected individuals, reduced the critical region by fine-mapping, and identified SIL1 as a gene underlying MSS. We found a common homozygous founder mutation in all Finnish patients. The same mutation was also present in patient samples from Norway and Sweden. Altogether, we identified eight mutations in SIL1, including nonsense, frameshift, splice site alterations, and one missense mutation. SIL1 encodes a nucleotide exchange factor for the endoplasmic reticulum (ER) resident heat-shock protein 70 chaperone GRP78. GRP78 functions in protein synthesis and quality control of the newly synthesized polypeptides. It senses and responds to stressful cellular conditions. We showed that in mice, SIL1 and GRP78 show highly similar spatial and temporal tissue expression in developing and mature brain, eye, and muscle. Studying endogenous proteins in mouse primary hippocampal neurons, we found that SIL1 and GRP78 colocalize and that SIL1 localizes to the ER. We studied the subcellular localization of two mutant proteins, a missense mutant found in two patients and an artificial mutant lacking the ER retrieval signal, and found that both mutant proteins formed aggregates within the ER. Well in line with our findings and the clinical features of MSS, recent work by Zhao et al. showed that a truncation of SIL1 causes ataxia and cerebellar Purkinje cell loss in the naturally occurring woozy mutant mouse. Prior to Purkinje cell degeneration, the unfolded protein response is initiated and abnormal protein accumulations are present. MSS thus joins the group of protein misfolding and accumulation diseases. These findings highlight the importance of SIL1 and the role of the ER in neuronal function and survival. The results presented in this thesis provide tools for the molecular genetic diagnostics of MSS and give a basis for future studies on the molecular pathogenesis of MSS. Understanding the mechanisms behind this pleiotropic syndrome may provide insights into more common forms of ataxia, myopathy, and neurodegeneration.

MENTAL HEALTH AND CRIMINALITY AMONG PSYCHIATRIC OFFENDERS IN SOUTHEASTERN ONTARIO

OBJECTIVES: (1) Describe the population of mentally ill offenders over whom Ontario Review Board (ORB) held jurisdiction. (2) Assess the influences of psychopathology and criminal factors on criminal career. METHOD: This study was a retrospective case series design that reviewed all offenders who were court ordered for psychiatric evaluation at Mental Health Services Site of Providence Care in Kingston, Ontario from 1993 to 2007 (N=347). Eighty five subjects were found not criminally responsible on the account of mental disorder and were included in statistical analysis (n=85). Bivariate associations between five key variables and two outcome variables, seriousness of crime and recidivism, were examined. Logistic regressions were conducted to test the role of the predictor variables on the outcome variables. RESULTS: Age and change in principal psychiatric diagnosis over time were shown to be associated with seriousness of crime. Timing of psychiatric onset, early signs of deviance and change in diagnosis were shown to be associated with recidivism. On the whole, study population did not markedly vary in their distribution of variables by the outcome variables. Regression model included timing of psychiatric onset; psychiatric history; existence of criminal associate; child abuse history; and early signs of deviance. Recidivism was shown to be predicted by early signs of deviance (OR=8.154, p<0.05). Existence of criminal associates was shown to have substantial values of odds ratio at marginal significance (OR=7.577, p=0.13). CONCLUSION: Seriousness of crime is a complex factor that could not be sufficiently predicted by any one or combinations of study variables. Recidivism is better predicted by criminality factors than psychopathology. In the future, an exploratory analysis that more broadly examines the psychopathology and criminal factors in Canadian forensic population is needed. Findings from this study have important clinical and legal implications.

Genetic optimism:Framing genes and mental illness in the news

Over the past two decades the pace and specificity of discoveries associating genetics with mental illness has accelerated, which is reflected in an increase in news coverage about the genetics of mental disorder. The news media is a major source of public understanding of genetics and a strong influence on public discourse. This paper examines the news coverage of genetics and mental illness (i.e., bipolar illness and schizophrenia) over a 25 year period, emphasizing the peak period of 1987-1994. Using a sample of 110 news stories from 5 major American newspapers and 3 news magazines, we identify the frame of "genetic optimism" which dominated the reporting of genetics and mental illness beginning in the mid-1980s. The structure of the frame is comprised of 3 elements: a gene for the disorder exists; it will be found; and it will be good. New discoveries of genes were announced with great fanfare, but the most promising claims could not be replicated or were retracted in short order. Despite these disconfirmations, genetic optimism persisted in subsequent news stories. While the scientific accuracy of the gene stories is high, the genetic optimism frame distorts some of the findings, misrepresents and reifies the impact of genes on mental disorder, and leaves no space for critics or an examination of potential negative impacts. The stances of reporters, scientists and editors may all in different ways contribute to the perpetuation of genetic optimism. Genetic optimism presents an overly sanguine picture of the state of genetics; as we enter the genetic age it is important to balance the extraneous "hype and hope" contained in news stories of genetics and mental illness.

Using extended contact to improve physiological responses and behavior toward people with schizophrenia

Extended contact has been shown to improve explicit and implicit attitudes toward a number of outgroups, but not yet toward people with mental health conditions. Using people with schizophrenia as the target group, this experiment is the first to demonstrate that extended contact can reduce explicit prejudice, buffer stress responses to future interactions, improve non-verbal behavior, and improve the quality of interactions in a manner detectable by the target group member. Participants watched a video of a brief, positive interaction between two strangers, one of whom they were led to believe had schizophrenia. Control participants watched the same video without being told that the person had schizophrenia. They then participated in a social interaction with a confederate whom they were led to believe had the disorder. Participants' cardiovascular and electrodermal activity were monitored immediately before the interaction. The interaction was also secretly recorded to allow independent judges to assess the participants' non-verbal behaviors. The confederate also rated the positivity of each interaction. Participants in the extended contact condition reported more positive attitudes toward people with schizophrenia, displayed more positive non-verbal behaviors, and had a more positive interaction with the confederate. Moreover, just prior to the interaction, participants in the extended contact condition displayed smaller anticipatory stress responses, as reflected in smaller changes in interbeat interval and non-specific skin conductance responses during this phase. Together, these findings support the use of the extended contact as an intervention that could lead to genuine changes in attitudes toward and treatment of people with severe mental health disorders.

A saúde mental dos sem abrigo: comunidades de inserção

Pretendemos com este estudo caracterizar os sem abrigo, as suas redes e relações sociais, bem como os modelos de intervenção, de forma a que se possa ter um maior conhecimento acerca desta problemática. Para a consecução destes propósitos, foram delineados os seguintes objectivos: caracterizar a população sem abrigo em termos de variáveis sócio-demográficas; identificar a sua rede social de apoio; caracterizar as dimensões sociais associadas à vinculação adulta nos sem abrigo; caracterizar a incidência de psicopatologia nesta população; analisar o seu bem estar psicológico; caracterizar os acontecimentos de vida stressantes que contribuem para a emergência desta problemática. Para atingir estes objectivos foram realizados dois estudos, um de carácter quantitativo e um segundo de carácter qualitativo. Participaram 225 indivíduos (105 sem abrigo e 120 pessoas carenciadas) garantindo a homogeneidade nas variáveis sexo e idade. A média de idades da amostra total (n= 225) é de 38 anos, sendo que a maioria dos sujeitos desta investigação pertence ao sexo masculino (78,5%). O grupo dos sem abrigo foi recolhido em duas comunidades de inserção, na zona centro do país, sendo importante destacar que todos nesta fase têm apoio residencial, satisfação das necessidades básicas, acompanhamento social e psicológico, bem como, projectos de inserção em curso. O protocolo de recolha de informação inclui dados pessoais, a versão portuguesa da (ASQ)-Questionário de Estilos de Vinculação nos Sem Abrigo (QEVSA), da escala de ocorrência de acontecimentos de vida stressantes relacionados com o surgimento do primeiro episódio de sem abrigo (EAVSSA), do Questionário de Morbilidade Psiquiátrica em Adultos (QMPA), do Medical Outcomes Study’s social support scale (MOS-SSS-P), a escala de medida de manifestação de bem-estar psicológico (EMMBEP), o programa de intervenção da CINO e uma entrevista estruturada utilizada no estudo qualitativo. Os principais resultados são: a) o perfil de sem abrigo encontrado é maioritariamente homem, em média com 39 anos, solteiro ou divorciado, com 1 filho, 2.º ciclo de escolaridade, desempregado e português; b) maioria viveu na rua mais de um ano, está na instituição há menos de meio ano, não teve nos últimos seis meses consumo de substâncias (álcool e drogas), frequenta consultas (saúde mental e toxicodependência), toma medicação (terapêutica de substituição e neurolépticos), afirma não ter comportamentos de risco, e na maioria têm patologia infecciosa (HIV ou hepatite c), tendo cerca de 40% estado detidos; c) a problemática dos sem abrigo é um fenómeno multicausal apontando como principais factores o conflito familiar, o desemprego e problemas de saúde; d) em termos de vinculação população sem abrigo parece corresponder a indivíduos com vinculação insegura, denotando uma falta de confiança generalizada; e) em termos de bem estar psicológico a média foi significativamente superior no grupo de pessoas carenciadas, quando comparado com o grupo dos sem abrigo; f) no que toca à saúde mental constatamos que 80% dos sem abrigo e 42.5% das pessoas carenciadas são portadores de transtorno mental; g) no que concerne ao apoio social os sem abrigo referem menor suporte social (apoio emocional, afectivo, instrumental e menor interacção social positiva) que as pessoas carenciadas; h) os sem abrigo têm menos familiares e amigos íntimos; i) os resultados do estudo qualitativo indicam que o programa de intervenção da CINO, parece contribuir para a emergência de uma rede social estável, activa, acessível e integrada que se constitui como um sistema salutogénico para o indivíduo, diminuindo o uso dos serviços. Parece ainda eficaz aos olhos dos próprios e destacam como factor fundamental a sua participação activa no mesmo, a importância de rotinas organizadoras, de espaços de terapia de grupo e a existência de equipa multidisciplinar. Destacam ainda como positivo o facto de existir um primeiro período de regime fechado como estratégia de prevenção de recaída, um programa faseado de aquisição de responsabilidades e autonomia, acesso a emprego no exterior da comunidade e o follow-up pós autonomização. Como implicação deste trabalho salienta-se a produção de conhecimentos acerca da realidade dos sem abrigo na região centro do país e de estratégias de intervenção.
