Metacognitive narrative psychotherapy for people diagnosed with schizophrenia : an outline of a principle-based treatment manual

Schizophrenia is often characterised by diminished self-experience. This article describes the development and principles of a manual for a psychotherapeutic treatment model that aims to enhance self-experience in people diagnosed with schizophrenia. Metacognitive Narrative Psychotherapy draws upon dialogical theory of self and the work of Lysaker and colleagues, in conjunction with narrative principles of therapy as operationalised by Vromans. To date, no manual for a metacognitive narrative approach to the treatment of schizophrenia exists. After a brief description of narrative understandings of schizophrenia, the development of the manual is described. Five general phases of treatment are outlined: (1) developing a therapeutic relationship; (2) eliciting narratives; (3) enhancing metacognitive capacity; (4) enriching narratives, and; (5) living enriched narratives. Proscribed practices are also described. Examples of therapeutic interventions and dialogue are provided to further explain the application of interventions in-session. The manual has been piloted in a study investigating the effectiveness of Metacognitive Narrative Psychotherapy in the treatment of people diagnosed with schizophrenia spectrum disorders.

Key-elements of family interventions for psychosis : a qualitative research

RESUMO:As perturbações psicóticas são doenças mentais complexas sendo influenciadas na sua etiologia e prognóstico por factores biológicos e psicossociais. A interferência do ambiente familiar na evolução da doença espelha bem esta realidade. Quando em 1962 George Brown e colaboradores descobriram que ambientes familiares com elevada Emoção Expressa (EE) contribuíam para um aumento significativo do número de recaídas de pessoas com esquizofrenia (Brown et al., 1962), estava aberto o caminho para o desenvolvimento de novas intervenções familiares. A EE inclui cinco componentes: três componentes negativos, i.e. criticismo, hostilidade e envolvimento emocional excessivo; e dois componentes positivos, i.e. afectividade e apreço (Amaresha & Venkatasubramanian, 2012; Kuipers et al., 2002). No final dos anos 1970 surgiram os primeiros trabalhos na área das intervenções familiares nas psicoses (IFP). Dois grupos em países diferentes, no Reino Unido e nos Estados Unidos da América, desenvolveram quase em simultâneo duas abordagens distintas. Em Londres, a equipa liderada por Julian Leff desenhava uma intervenção combinando sessões unifamiliares em casa, incluindo o paciente, e sessões em grupo, apenas para os familiares (Leff et al., 1982). Por seu turno, em Pittsburgh, Gerard Hogarty e colaboradores desenvolviam uma abordagem que compreendia a dinamização de sessões educativas em grupo (Anderson e tal., 1980). Para designar este trabalho, Hogarty e colaboradores propuseram o termo “psicoeducação”. As IFP começaram a ser conhecidas por esta designação que se generalizou até aos dias de hoje. Neste contexto a educação era vista como a partilha de informação acerca da doença, dos profissionais para os familiares. Nas sessões os profissionais eram informados acerca das manifestações, etiologia, tratamento e evolução das psicoses, bem como de formas para lidar com as situações difíceis geradas pela doença, e.g. risco de recaída. Os trabalhos pioneiros das IFP foram rapidamente sucedidos pelo desenvolvimento de novos modelos e a proliferação de estudos de eficácia. Para além dos modelos de Leff e Hogarty, os modelos IFP que ficaram mais conhecidos foram: (1) a Terapia Familiar-Comportamental, desenvolvida por Ian Falloon e colaboradores (Falloon et al., 1984); e (2) a Terapia Multifamiliar em Grupo, desenvolvida por William McFarlane e colaboradores (McFarlane, 1991). O incremento de estudos de eficácia contribuiu rapidamente para as primeiras meta-análises. Estas, por sua vez, resultaram na inclusão das IFP nas normas de orientação clínica mais relevantes para o tratamento das psicoses, nomeadamente da esquizofrenia (e.g. PORT Recomendations e NICE Guidelines). No geral os estudos apontavam para uma diminuição do risco de recaída na esquizofrenia na ordem dos 20 a 50% em dois anos (Pitschel-Walz et al., 2001). No final dos anos 1990 as IFP atingiam assim o apogeu. Contudo, a sua aplicação prática tem ficado aquém do esperado e as barreiras à implementação das IFP passaram a ser o foco das atenções (Gonçalves-Pereira et al., 2006; Leff, 2000). Simultaneamente, alguns autores começaram a levantar a questão da incerteza sobre quais os elementos-chave da intervenção. O conhecimento sobre o processo das IFP era reduzido e começaram a surgir as primeiras publicações sobre o assunto (Lam, 1991). Em 1997 foi dinamizada uma reunião de consenso entre os três investigadores mais relevantes do momento, Falloon, Leff e McFarlane. Deste encontro promovido pela World Schizophrenia Fellowship for Schizophrenia and Allied Disorders surgiu um documento estabelecendo dois objectivos e quinze princípios para as IFP (WFSAD, 1997). Não obstante os contributos que foram feitos, continua a existir uma grande falta de evidência empírica acerca do processo das IFP e dos seus elementos-chave (Cohen et al., 2008; Dixon et al., 2001; Lam, 1991; Leff, 2000; McFarlane et al., 2003). Também em Portugal, apesar da reflexão teórica nesta área e do registo de ensaios de efectividade de grupos para familiares – estudo FAPS (Gonçalves-Pereira, 2010), os componentes fundamentais das IFP nunca foram analisados directamente. Assim, o projecto de investigação descrito nesta tese teve como objectivo identificar os elementos-chave das IFP com base em investigação qualitativa. Para tal, conduzimos três estudos que nos permitiriam alcançar dados empíricos sobre o tema. O primeiro estudo (descrito no Capítulo 2) consistiu na realização de uma revisão sistemática da literatura científica acerca das variáveis relacionadas com o processo das IFP. A nossa pesquisa esteve focada essencialmente em estudos qualitativos. Contudo, decidimos não restringir demasiado os critérios de inclusão tendo em conta as dificuldades em pesquisar sobre investigação qualitativa nas bases de dados electrónicas e também devido ao facto de ser possível obter informação sobre as variáveis relacionadas com o processo a partir de estudos quantitativos. O método para este estudo foi baseado no PRISMA Statement para revisões sistemáticas da literatura. Depois de definirmos os critérios de inclusão e exclusão, iniciámos várias pesquisas nas bases de dados electrónicas utilizando termos booleanos, truncações e marcadores de campo. Pesquisámos na PubMed/MEDLINE, Web of Science e nas bases de dados incluídas na EBSCO Host (Academic Search Complete; Education Research Complete; Education Source; ERIC; and PsycINFO). As pesquisas geraram 733 resultados. Depois de serem removidos os duplicados, 663 registos foram analisados e foram seleccionados 38 artigos em texto integral. No final, 22 artigos foram incluídos na síntese qualitativa tendo sido agrupados em quatro categorias: (1) estudos examinando de forma abrangente o processo; (2) estudos acerca da opinião dos participantes sobre a intervenção que receberam; (3) estudos comparativos que individualizaram variáveis sobre o processo; e (4) estudos acerca de variáveis mediadoras. Os resultados evidenciaram um considerável hiato na investigação em torno do processo das IFP. Identificámos apenas um estudo que abordava de forma abrangente o processo das IFP (Bloch, et al., 1995). Este artigo descrevia uma análise qualitativa de um estudo experimental de uma IFP. Contudo, as suas conclusões gerais revelaramse pobres e apenas se podia extrair com certeza de que as IFP devem ser baseadas nas necessidades dos participantes e que os terapeutas devem assumir diferentes papéis ao longo da intervenção. Da revisão foi possível perceber que os factores terapêuticos comuns como a aliança terapêutica, empatia, apreço e a “aceitação incondicional”, podiam ser eles próprios um elemento isolado para a eficácia das IFP. Outros estudos enfatizaram a educação como elemento chave da intervenção (e.g. Levy-Frank et al., 2011), ao passo que outros ainda colocavam a ênfase no treino de estratégias para lidar com a doença i.e. coping (e.g. Tarrier et al., 1988). Com base nesta diversidade de resultados e tendo em conta algumas propostas prévias de peritos (McFarlane, 1991; Liberman & Liberman, 2003), desenvolvemos a hipótese de concebermos as IFP como um processo por etapas, de acordo com as necessidades dos familiares. No primeiro nível estariam as estratégias relacionadas com os factores terapêuticos comuns e o suporte emocional,no segundo nível a educação acerca da doença, e num nível mais avançado, o foco seria o treino de estratégias para lidar com a doença e diminuir a EE. Neste estudo concluímos que nem todas as famílias iriam precisar de IFP complexas e que nesses casos seria possível obter resultados favoráveis com IFP pouco intensas. O Estudo 2 (descrito no Capítulo 3) consistiu numa análise qualitativa dos registos clínicos do primeiro ensaio clínico da IFP de Leff e colaboradores (Leff et al., 1982). Este ensaio clínico culminou numa das evidências mais substanciais alguma vez alcançada com uma IFP (Leff et al., 1982; Leff et al., 1985; Pitschel-Walz et al., 2001). Este estudo teve como objectivo modular a EE recorrendo a um modelo misto com que compreendia sessões familiares em grupo e algumas sessões unifamiliares em casa, incluindo o paciente. Os resultados mostraram uma diminuição das recaídas em nove meses de 50% no grupo de controlo para 8% no grupo experimental. Os registos analisados neste estudo datam do período de 1977 a 1982 e podem ser considerados como material histórico de alto valor, que surpreendentemente nunca tinha sido analisado. Eram compostos por descrições pormenorizadas dos terapeutas, incluindo excertos em discurso directo e estavam descritos segundo uma estrutura, contendo também os comentários dos terapeutas. No total os registos representavam 85 sessões em grupo para familiares durante os cinco anos do ensaio clínico e 25 sessões unifamiliares em casa incluindo o paciente. Para a análise qualitativa decidimos utilizar um método de análise dedutivo, com uma abordagem mecânica de codificação dos registos em categorias previamente definidas. Tomámos esta decisão com base na extensão apreciável dos registos e porque tínhamos disponível informação válida acerca das categorias que iríamos encontrar nos mesmos, nomeadamente a informação contida no manual da intervenção, publicado sob a forma de livro, e nos resultados da 140 nossa revisão sistemática da literatura (Estudo 1). Deste modo, foi construída uma grelha com a estrutura de codificação, que serviu de base para a análise, envolvendo 15 categorias. De modo a cumprir com critérios de validade e fidelidade rigorosos, optámos por executar uma dupla codificação independente. Deste modo dois observadores leram e codificaram independentemente os registos. As discrepâncias na codificação foram revistas até se obter um consenso. No caso de não ser possível chegar a acordo, um terceiro observador, mais experiente nos aspectos técnicos das IFP, tomaria a decisão sobre a codificação. A análise foi executada com recurso ao programa informático NVivo® versão 10 (QSR International). O número de vezes que cada estratégia foi utilizada foi contabilizado, especificando a sessão e o participante. Os dados foram depois exportados para uma base de dados e analisados recorrendo ao programa informático de análise estatística SPSS® versão 20 (IBM Corp.). Foram realizadas explorações estatísticas para descrever os dados e obter informação sobre possíveis relações entre as variáveis. De modo a perceber a significância das observações, recorremos a testes de hipóteses, utilizando as equações de estimação generalizadas. Os resultados da análise revelaram que as estratégias terapêuticas mais utilizadas na intervenção em grupo foram: (1) a criação de momentos para ouvir as necessidades dos participantes e para a partilha de preocupações entre eles – representando 21% de todas as estratégias utilizadas; (2) treino e aconselhamento acerca de formas para lidar com os aspectos mais difíceis da doença – 15%; (3) criar condições para que os participantes recebam suporte emocional – 12%; (4) lidar com o envolvimento emocional excessivo 10%; e (5) o reenquadramento das atribuições dos familiares acerca dos comportamentos dos pacientes – 10%. Nas sessões unifamiliares em casa, as estratégias mais utilizadas foram: (1) lidar com o envolvimento emocional excessivo – representando 33% de todas as estratégias utilizadas nas sessões unifamiliares em casa; (2) treino e aconselhamento acerca de formas para lidar com os aspectos desafiadores da doença – 22%; e (3) o reenquadramento das atribuições dos familiares acerca dos comportamentos dos pacientes, juntamente com o lidar com a zanga, o conflito e a rejeição – ambas com 10%. A análise longitudinal mostrou que a criação de momentos para ouvir as necessidades dos familiares tende a acontecer invariavelmente ao longo do programa. Sempre que isso acontece, são geralmente utilizadas estratégias para ajudar os familiares a lidarem melhor com os aspectos difíceis da doença e estratégias para fomentar o suporte emocional. Por sua vez, foi possível perceber que o trabalho para diminuir o envolvimento emocional excessivo pode acontecer logo nas primeiras sessões. O reenquadramento e o lidar com a zanga/ conflito/ rejeição tendem a acontecer a partir da fase intermédia até às últimas sessões. A análise das diferenças entre os familiares com baixa EE e os de elevada EE, mostrou que os familiares com elevada EE tendem a tornar-se o foco da intervenção grupal. Por sua vez, os familiares com baixa EE recebem mais estratégias relacionadas com aliança terapêutica, comparativamente com os familiares com elevada EE. São de realçar os dados relativamente às estratégias educativas. Foi possível observar que estas tendem a acontecer mais no início dos grupos, não estando associadas a outras estratégias. Contudo é de notar a sua baixa utilização, a rondar apenas os 5%.O Estudo 3 (descrito no Capítulo 4) surgiu como uma forma de completar a análise do Estudo 2, permitindo uma visão mais narrativa do processo e focando, adicionalmente, as mudanças que ocorrem nos participantes. Com base nos mesmos registos utilizados no Estudo 2, codificámos de forma secundária os registos em duas categorias i.e. marcadores de mudança e marcadores emocionais. Os marcadores de mudança foram cotados sempre que um participante exibia comportamentos ou pensamentos diferentes dos anteriores no sentido de uma eventual redução na EE. Os marcadores emocionais correspondiam à expressão intensa de sentimentos por parte dos participantes nas sessões e que estariam relacionados com assuntos-chave para essas pessoas. Os excertos que continham a informação destes marcadores foram posteriormente revistos e articulados com notas e comentários não estruturados que recolhemos durante a codificação do Estudo 2. Com base nesta informação os registos foram revistos e, utilizando um método indutivo, elaborámos uma narrativa acerca da intervenção. Os resultados da narrativa foram discutidos com dados de que dispúnhamos, referentes a reuniões com os terapeutas envolvidos na intervenção em análise (Elizabeth Kuipers, Ruth Berkowitz e Julian Leff; Londres, Novembro de 2011). Reconhecemos que, pela sua natureza não estruturada e indutiva, a avaliação narrativa está mais sujeita ao viés de observador. Não obstante, os resultados deste Estudo 3 parecem revestir uma consistência elevada. O mais relevante foi a evidência de que na intervenção em análise ocorreram mudanças emocionais significativas nos familiares ao longo das sessões em grupo. Numa fase inicial os familiares tenderam a expressar sentimentos de zanga. Seguidamente, os terapeutas iam nterrompendo o discurso de reminiscências, direccionavam o discurso para as suas preocupações actuais e os familiares pareciam ficar mais calmos. Contudo, à medida que os 143 participantes “mergulhavam” nos problemas com que se confrontavam na altura, os sentimentos de zanga davam lugar a sentimentos de perda e angústia. Nessa altura os terapeutas enfatizavam o suporte emocional e introduziam progressivamente técnicas de reenquadramento para ajudar os participantes a avaliar de forma mais positiva as situações. Este trabalho dava lugar a sentimentos mais positivos, como a aceitação, apreço e a sensação de controlo. O Estudo 3 evidenciou também o que designamos como o “Efeito de Passagem de Testemunho”. Este efeito aconteceu sempre que um membro novo se juntava ao grupo. Os membros antigos, que estavam a ser o alvo das atenções e naturalmente a receber mais intervenção, mudam de papel e passam eles próprios a focar as suas atenções nos membros mais recentes do grupo, contribuindo para a dinâmica do grupo com as mesmas intervenções que os ajudaram previamente. Por exemplo, alguns membros antigos que eram altamente críticos nos grupos em relação aos seus familiares passavam a fazer comentários de reenquadramento dirigidos para os novos membros. Por fim, o Capítulo 5 resume as conclusões gerais deste projecto de investigação. Os estudos apresentados permitiram um incremento no conhecimento acerca do processo das IFP. Anteriormente esta informação era baseada sobretudo na opinião de peritos. Com este projecto aumentámos o nível de evidência ao apresentar estudos com base em dados empíricos. A análise qualitativa do Estudo 2 permitiu pela primeira vez, tanto quanto é do nosso conhecimento, perceber de forma aprofundada o processo subjacente a uma IFP (no contexto de um ensaio clínico que se revelou como um dos mais eficazes de sempre). Identificámos as estratégias mais utilizadas, as relações entre elas e a sua diferente aplicação entre familiares com baixa EE e familiares com alta EE.O Estudo 3 completou a informação incluindo aspectos relacionados com as mudanças individuais durante o programa. No final foi possível perceber que as IFP devem ser um programa por etapas. Nos Estudo 2 e 3, evidenciámos que numa fase inicial, os terapeutas dedicaram especial atenção para que os familiares tivessem espaço para partilharem as suas necessidades, disponibilizando logo de seguida estratégias para promover o suporte emocional e estratégias de coping. Num nível subsequente do programa, o trabalho terapêutico avançou para estratégias mais direccionadas para regular a EE, mantendo sempre as estratégias iniciais ao longo das sessões. Assim apesar de a educação ter sido um componente importante na IFP em análise, houve outras estratégias mais relevantes no processo. A evidência gerada pelos Estudos 2 e 3 baseou-se em registos históricos de elevado valor, sendo que os constructos subjacentes na época, nomeadamente a EE, continuam a ser a base da investigação e prática das IFP a nível mundial em diferentes culturas (Butzlaff & Hooley, 1998). Concluímos que as IFP são um processo complexo com diferentes níveis de intervenção, podendo gerar mudanças emocionais nos participantes durante as sessões. No futuro será importante replicar o nosso trabalho (nomeadamente o Estudo 2) com outras abordagens de IFP, de modo a obter informação acerca do seu processo. Esse conhecimento será fundamental para uma possível evolução do paradigma das IFP. ----------- ABSTRACT: Background: Psychotic-spectrum disorders are complex biopsychosocial conditions and family issues are important determinants of prognosis. The discovery of the influence of expressed emotion on the course of schizophrenia paved the road to the development of family interventions aiming to lower the “emotional temperature” in the family. These treatment approaches became widely recognised. Effectiveness studies showed remarkable and strong results in relapse prevention and these interventions were generalised to other psychotic disorders besides schizophrenia. Family interventions for psychosis (FIP) prospered and were included in the most important treatment guidelines. However, there was little knowledge about the process of FIP. Different FIP approaches all led to similar outcomes. This intriguing fact caught the attention of authors and attempts were made to identify the key-elements of FIP. Notwithstanding, these efforts were mainly based on experts’ opinions and the conclusions were scanty. Therefore, the knowledge about the process of FIP remains unclear. Aims: To find out which are the key-elements of FIP based on empirical data. Methods: Qualitative research. Three studies were conducted to explore the process of FIP and isolate variables that allowed the identification of the key-elements of FIP. Study 1 consisted of a systematic literature review of studies evaluating process-related variables of FIP. Study 2 subjected the intervention records of a formerly conducted effective clinical trial of FIP to a qualitative analysis. Records were analysed into categories and the emerging data were explored using descriptive statistics and generalised estimating equations. Study 3 consisted of a narrative evaluation using an inductive qualitative approach, examining the same data of Study 2. Emotional markers and markers of change were identified in the records and the content of these excerpts was synthesised and discussed. Results: On Study 1, searches revealed 733 results and 22 papers were included in the qualitative synthesis. We found a single study comprehensively exploring the process of FIP. All other studies focused on particular aspects of the process-related variables. The key-elements of FIP seemed to be the so-called “common therapeutic factors”, followed by education about the illness and coping skills training. Other elements were also identified, as the majority of studies evidenced a multiple array of components. Study 2,revealed as the most used strategies in the intervention programme we analysed: the addressing of needs; sharing; coping skills and advice; emotional support; dealing with overinvolvement; and reframing relatives’ views about patients’ behaviours. Patterns of the usefulness of the strategies throughout the intervention programme were identified and differences between high expressed emotion and low expressed emotion relatives were elucidated. Study 3 accumulated evidence that relatives experience different emotions during group sessions, ranging from anger to grief, and later on, to acceptance and positive feelings. Discussion: Study 1 suggested a stepped model of intervention according to the needs of the families. It also revealed a gap in qualitative research of FIP. Study 2 demonstrated that therapists of the trial under analysis often created opportunities for relatives to express and share their concerns throughout the entire treatment programme. The use of this strategy was immediately followed by coping skills enhancement, advice and emotional support. Strategies aiming to deal with overinvolvement may also occur early in the treatment programme. Reframing was the next most used strategy, followed by dealing with anger, conflict and rejection. This middle and later work seems to operate in lowering criticism and hostility, while the former seems to diminish overinvolvement. Single-family sessions may be used to augment the work developed in the relatives groups. Study 3 revealed a missing part of Study 2. It demonstrated that the process of FIP promotes emotional changes in the relatives and therapists must be sensitive to the emotional pathway of each participant in the group.

Comparing the prodrome of schizophrenia-spectrum psychoses and affective disorders with and without psychotic features

Following encouraging results in the early detection of psychotic disorders, interest in the early detection of affective, especially bipolar disorders, has recently been renewed. However, the differentiation between affective disorders with and without psychotic features is often missing, although it has been suggested that affective disorders with psychotic features may be distinct from those without psychotic features and closely linked to non-affective psychoses.

Molecular Validation of the Schizophrenia Spectrum

Background: Early descriptive work and controlled family and adoption studies support the hypothesis that a range of personality and nonschizophrenic psychotic disorders aggregate in families of schizophrenic probands. Can we validate, using molecular polygene scores from genome-wide association studies (GWAS), this schizophrenia spectrum? Methods: The predictive value of polygenic findings reported by the Psychiatric GWAS Consortium (PGC) was applied to 4 groups of relatives from the Irish Study of High-Density Schizophrenia Families (ISHDSF; N = s) differing on their assignment within the schizophrenia spectrum. Genome-wide single nucleotide polymorphism data for affected and unaffected relatives were used to construct per-individual polygene risk scores based on the PGC stage-I results. We compared mean polygene scores in the ISHDSF with mean scores in ethnically matched population controls (N = 929). Results: The schizophrenia polygene score differed significantly across diagnostic categories and was highest in those with narrow schizophrenia spectrum, lowest in those with no psychiatric illness, and in-between in those classified in the intermediate, broad, and very broad schizophrenia spectrum. Relatives of all of these groups of affected subjects, including those with no diagnosis, had schizophrenia polygene scores significantly higher than the control sample. Conclusions: In the relatives of high-density families, the observed pattern of enrichment of molecular indices of schizophrenia risk suggests an underlying, continuous liability distribution and validates, using aggregate common risk alleles, a genetic basis for the schizophrenia spectrum disorders. In addition, as predicted by genetic theory, nonpsychotic members of multiply-affected schizophrenia families are significantly enriched for replicated, polygenic risk variants compared with the general population.

Elevated bilirubin in acute and transient psychotic disorder

Mild unconjugated hyperbilirubinemia seems to be more common in patients with disorders from the schizophrenic spectrum than in other psychiatric patients or in the general population and has been linked to brain alterations. This spectrum however contains a number of diagnostic entities that might not share the same etiological and environmental factors.

Cerebral connectivity and psychotic personality traits : A diffusion tensor imaging study

This study aims to investigate the relationship between regional connectivity in the brain white matter and the presence of psychotic personality traits, in healthy subjects with psychotic traits. Thirteen healthy controls were administered the MMPI-2, to assess psychotic traits and, according to MMPI results, a dichotomization into a group of "high-psychotic" and "low-psychotic" was performed. Diffusion tensor imaging (DTI) was used as a non-invasive measure, in order to obtain information about the fractional anisotropy (FA), an intravoxel index of local connectivity and, by means of a voxelwise approach, the between-group differences of the FA values were calculated. The "high-psychotic" group showed higher FA in the left arcuate fasciculus. Subjects with low scores for psychotic traits had significantly higher FA in the corpus callosum, right arcuate fasciculus, and fronto-parietal fibers. In line with previous brain imaging studies of schizophrenia spectrum disorders, our results suggest that psychotic personality traits are related to altered connectivity and brain asymmetry.

Lack of concordance between subjective improvement and symptom change in psychotic episodes

OBJECTIVES: Subjective, self-rated improvement in patients with schizophrenia spectrum disorders can carry significance as a first-person account of treatment outcome, and can be of importance for the individual patient's acceptance of further treatment, including psychological treatments. This study assessed the concordance between post-treatment subjective improvement and the observed symptom change after a psychotic episode. DESIGN: Longitudinal study based on daily symptom ratings. METHOD: The study sample consisted of 43 younger, primarily first- or second-episode patients. Observed symptom change was calculated as both pre-post differences and symptom trajectories. Subjective improvement was assessed at the end of treatment by using the 'Emotional and Behavioural Changes in Psychotherapy Questionnaire' (VEV), a retrospective measure of subjective change. RESULTS: The findings indicated no significant concordance between pre-post differences in symptoms and self-rated improvement, nor were final levels of symptoms related to subjective improvement. Higher initial and mean symptom levels for positive symptoms were related to a lower degree of subjective improvement. A shorter duration of an initial trend-like improvement in psychosis was shown to be associated with greater subjective improvement. CONCLUSIONS: Subjective assessment of improvement may differ markedly from symptom change. In psychotic episodes, more severe initial positive symptoms as well as a delayed improvement of positive symptoms may be related to a reduced subjective experience of improvement for the duration of the entire episode. The treatment of psychosis should take a possible discordance between subjective and objective change into account.

Shifted Coupling of EEG Driving Frequencies and fMRI Resting State Networks in Schizophrenia Spectrum Disorders

INTRODUCTION: The cerebral resting state in schizophrenia is altered, as has been demonstrated separately by electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) resting state networks (RSNs). Previous simultaneous EEG/fMRI findings in healthy controls suggest that a consistent spatiotemporal coupling between neural oscillations (EEG frequency correlates) and RSN activity is necessary to organize cognitive processes optimally. We hypothesized that this coupling is disorganized in schizophrenia and related psychotic disorders, in particular regarding higher cognitive RSNs such as the default-mode (DMN) and left-working-memory network (LWMN). METHODS: Resting state was investigated in eleven patients with a schizophrenia spectrum disorder (n = 11) and matched healthy controls (n = 11) using simultaneous EEG/fMRI. The temporal association of each RSN to topographic spectral changes in the EEG was assessed by creating Covariance Maps. Group differences within, and group similarities across frequencies were estimated for the Covariance Maps. RESULTS: The coupling of EEG frequency bands to the DMN and the LWMN respectively, displayed significant similarities that were shifted towards lower EEG frequencies in patients compared to healthy controls. CONCLUSIONS: By combining EEG and fMRI, each measuring different properties of the same pathophysiology, an aberrant relationship between EEG frequencies and altered RSNs was observed in patients. RSNs of patients were related to lower EEG frequencies, indicating functional alterations of the spatiotemporal coupling. SIGNIFICANCE: The finding of a deviant and shifted coupling between RSNs and related EEG frequencies in patients with a schizophrenia spectrum disorder is significant, as it might indicate how failures in the processing of internal and external stimuli, as commonly seen during this symptomatology (i.e. thought disorders, hallucinations), arise.

Rapid tranquilization of severely agitated patients with schizophrenia spectrum disorders: a naturalistic, rater-blinded, randomized, controlled study with oral haloperidol, risperidone, and olanzapine

INTRODUCTION Agitation is a major problem in acute schizophrenia. Only a few studies have tested antipsychotic agents in severely agitated patients, mainly because of legal issues. Furthermore, most studies were limited to the first 24 hours. We aimed to investigate the efficacy of oral haloperidol, risperidone, and olanzapine in reducing psychotic agitation in severely agitated patients with schizophrenia or schizophreniform or schizoaffective disorder over 96 hours using a prospective, randomized, rater-blinded, controlled design within a naturalistic treatment regimen. METHODS In total, 43 severely agitated patients at acute care psychiatric units were enrolled. Participants were randomly assigned to receive either daily haloperidol 15 mg, olanzapine 20 mg, or risperidone 2 to 6 mg over 5 days. Positive and Negative Syndrome Scale psychotic agitation subscale score was the primary outcome variable. A mixed-model analysis was applied. RESULTS All drugs were effective for rapid tranquilization within 2 hours. Over 5 days, the course differed between agents (P < 0.001), but none was superior. Dropouts occurred only in the risperidone and olanzapine groups. Men responded better to treatment than did women during the initial 2 hours (P = 0.046) as well as over the 5-day course (P < 0.001). No difference between drug groups was observed regarding diazepam or biperiden use. CONCLUSIONS Oral haloperidol, risperidone, and olanzapine seem to be suitable for treating acute severe psychotic agitation in schizophrenia spectrum disorders. Response to oral antipsychotics demonstrated a gender effect with poorer outcome in women throughout the study.

Rapid tranquilization of severely agitated patients with schizophrenia spectrum disorders: a naturalistic, rater-blinded, randomized controlled study with oral haloperidol, risperidone, and olanzapine

Agitation is a major problem in acute schizophrenia. Still, only limited evidence exists on antipsychotic efficacy in severely agitated patients after the first 24 hours. We aimed to investigate the efficacy of oral haloperidol, risperidone, and olanzapine in reducing psychotic agitation in severely agitated patients with schizophrenia or schizophreniform or schizoaffective disorder over 96 hours using a prospective, randomized, rater-blinded, controlled design within a naturalistic treatment regimen. We enrolled 43 severely agitated patients at acute care psychiatric units. Participants were randomly assigned to receive either daily haloperidol 15 mg, olanzapine 20 mg, or risperidone 2 – 6 mg over 5 days. Positive and Negative Syndrome Scale psychotic agitation (PANSS-PAS) subscore was the primary outcome variable. A mixed model analyses was applied. All drugs were effective for rapid tranquillization within 2 hours. Over 5 days, the course differed between agents (p < 0.001) but none was superior. Dropouts occurred only in the risperidone and olanzapine groups. Men responded better to treatment than women during the initial 2 hours (p = 0.046) as well as over the 5 day course (p < 0.001). No difference between drug groups was observed regarding diazepam or biperiden use. Oral haloperidol, risperidone, and olanzapine seem to be suitable for treating acute severe psychotic agitation in schizophrenia spectrum disorders. We observed a gender effect with poorer outcome in women.

Effectiveness of integrated care including therapeutic assertive community treatment in severe schizophrenia spectrum and bipolar I disorders: the 24-month follow-up ACCESS II study

OBJECTIVE The ACCESS treatment model offers assertive community treatment embedded in an integrated care program to patients with psychoses. Compared to standard care and within a controlled study, it proved to be more effective in terms of service disengagement and illness outcomes in patients with schizophrenia spectrum disorders over 12 months. ACCESS was implemented into clinical routine and its effectiveness assessed over 24 months in severe schizophrenia spectrum disorders and bipolar I disorder with psychotic features (DSM-IV) in a cohort study. METHOD All 115 patients treated in ACCESS (from May 2007 to October 2009) were included in the ACCESS II study. The primary outcome was rate of service disengagement. Secondary outcomes were change of psychopathology, severity of illness, psychosocial functioning, quality of life, satisfaction with care, medication nonadherence, length of hospital stay, and rates of involuntary hospitalization. RESULTS Only 4 patients (3.4%) disengaged with the service. Another 11 (9.6%) left because they moved outside the catchment area. Patients received a mean of 1.6 outpatient contacts per week. Involuntary admissions decreased from 34.8% in the 2 previous years to 7.8% during ACCESS (P < .001). Mixed models repeated-measures analyses revealed significant improvements among all patients in psychopathology (effect size d = 0.64, P < .001), illness severity (d = 0.84, P = .03), functioning level (d = 0.65, P < .001), quality of life (d = 0.50, P < .001), and client satisfaction (d = 0.11, P < .001). At 24 months, 78.3% were fully adherent to medication, compared to 25.2% at baseline (P = .002). CONCLUSIONS ACCESS was successfully implemented in clinical routine and maintained excellent rates of service engagement and other outcomes in patients with schizophrenia spectrum disorders or bipolar I disorder with psychotic features over 24 months.

There have been numerous attempts to reveal the neurobiological basis of schizophrenia spectrum disorders. Results however, remain as heterogeneous as the schizophrenia spectrum disorders itself. Therefore, one aim of this thesis was to divide patients affected by this disorder into subgroups in order to homogenize the results of future studies. In a first study it is suggested that psychopathological rating scales should focus on symptoms-clusters that may have a common neurophysiological background. The here presented Bern Psychopathology Scale (BPS) proposes that alterations in three wellknown brain systems (motor, language, and affective) are largely leading to the communication failures observable on a behavioral level, but also - as repeatedly hypothesized - to dysconnectivity within and between brain systems in schizophrenia spectrum disorders. The external validity of the motor domain in the BPS was tested against the objective measure of 24 hours wrist actigraphy, in a second study. The subjective, the quantitative, as well as the global rating of the degree of motor disorders in this patient group showed significant correlations to the acquired motor activity. This result confirmed in a first step the practicability of the motor domain of the BPS, but needs further validation regarding pathological brain alterations. Finally, in a third study (independent from the two other studies), two cerebral Resting State Networks frequently altered in schizophrenia were investigated for the first time using simultaneous EEG/fMRI: The well-known default mode network and the left working memory network. Besides the changes in these fMRI-based networks, there are well-documented findings that patients exhibit alterations in EEG spectra compared to healthy controls. However, only through the multimodal approach it was possible to discover that patients with schizophrenia spectrum disorders have a slower driving frequency of the Resting State Networks compared to the matched healthy controls. Such a dysfunctional coupling between neuronal frequency and functional brain organization could explain in a uni- or multifactorial way (dysfunctional cross-frequency coupling, maturational effects, vigilance fluctuations, task-related suppression), how the typical psychotic symptoms might occur. To conclude, the major contributions presented in this thesis were on one hand the development of a psychopathology rating scale that is based on the assumption of dysfunctional brain networks, as well as the new evidence of a dysfunctional triggering frequency of Resting State Networks from the simultaneous EEG/fMRI study in patients affected by a schizophrenia spectrum disorder.

Self-reported attenuated psychotic-like experiences in help-seeking adolescents and their association with age, functioning and psychopathology

OBJECTIVE Self-rated attenuated psychotic-like experiences (APLEs) are increasingly used to screen for ultra-high-risk (UHR) across all ages. However, self-rated psychotic-like experiences (PLEs), in particular perception-related ones, were more frequent in children and adolescents, in which they possessed less clinical significance. We therefore explored the prevalence of different factors of APLEs in help-seeking adolescents, and their relationship with age, functioning and psychopathology METHOD As a part of the "Liberiamo il Futuro" project, help-seeking adolescents (N=171; 11-18years, 53% male) were screened with the 92-item Prodromal Questionnaire (PQ-92). A factor analysis was performed on the PQ-92 positive items (i.e., APLEs) to identify different APLE-factors. These were assessed for their association with age, functioning and psychopathology using regression analyses. RESULTS APLEs were very common in help-seeking adolescents, and formed four factors: "Conceptual Disorganization and Suspiciousness", "Perceptual Abnormalities", "Bizarre Experiences", and "Magical Ideation". Associations with age and functioning but not psychopathology were found for "Perceptual Abnormalities" that was significantly more severe in 11-12-year-olds, while "Conceptual Disorganization and Suspiciousness" was significantly related to psychopathology. CONCLUSION In line with findings on PLEs, prevalence and clinical significance of APLEs, especially perception-related ones, might depend on age and thus neurodevelopmental stage, and may fall within the normal spectrum of experience during childhood. This should be considered when screening for UHR status in younger age groups

Cenesthopathy in adolescence: An appraisal of diagnostic overlaps along the anxiety–hypochondriasis–psychosis spectrum

Objective To discuss the diagnostic validity of unusual bodily perceptions along the spectrum from age-specific, often transitory and normal, to pathological phenomena in adolescence to hypochondriasis and finally to psychosis. Methods Critical literature review of the cornerstone diagnostic groups along the spectrum embracing anxiety and cenesthopathy in adolescence, hypochondriasis, and cenesthopathy and psychosis, followed by a discussion of the diagnostic overlaps along this spectrum. Results The review highlights significant overlaps between the diagnostic cornerstones. It is apparent that adolescents with unusual bodily perceptions may conceptually qualify for more than one diagnostic group along the spectrum. To determine whether cenesthopathies in adolescence mirror emerging psychosis, a number of issues need to be considered, i.e. age and mode of onset, gender, level of functioning and drug use. The role of overvalued ideas at the border between hypochondriasis and psychosis must be considered. Conclusion As unusual bodily symptoms may in some instances meet formal psychosis risk criteria, a narrow understanding of these symptoms may lead to both inappropriate application of the new DSM-5 attenuated psychosis syndrome and of treatment selection. On the other hand, the possibility of a psychotic dimension of unusual bodily symptoms in adolescents must always be considered as most severe expression of the cenesthopathy spectrum.

Gesture performance in first- and multiple-episode patients with schizophrenia spectrum disorders

BACKGROUND/AIM Gesturing plays an important role in social behavior and social learning. Deficits are frequent in schizophrenia and may contribute to impaired social functioning. Information about deficits during the course of the disease and presence of severity and patterns of impairment in first-episode patients is missing. Hence, we aimed to investigate gesturing in first- compared to multiple-episode schizophrenia patients and healthy controls. METHODS In 14 first-episode patients, 14 multiple-episode patients and 16 healthy controls matched for age, gender and education, gesturing was assessed by the comprehensive Test of Upper Limb Apraxia. Performance in two domains of gesturing - imitation and pantomime - was recorded on video. Raters of gesture performance were blinded. RESULTS Patients with multiple episodes had severe gestural deficits. For almost all gesture categories, performance was worse in multiple- than in first-episode patients. First-episode patients demonstrated subtle deficits with a comparable pattern. CONCLUSIONS Subjects with multiple psychotic episodes have severe deficits in gesturing, while only mild impairments were found in first-episode patients independent of age, gender, education and negative symptoms. The results indicate that gesturing is impaired at the onset of disease and likely to further deteriorate during its course.
