Estudo sobre o insight em pessoas com psicose

Para além das variáveis clínicas e sociodemográficas existem concerteza importantes componentes individuais que desempenham um contributo importante no nível de insight apresentado por cada pessoa doente, por exemplo, o nível de inteligência, personalidade, cultura, experiências passadas, memória, etc. A natureza clínica, emocional e/ou intelectual do termo ajuda-nos a compreender a complexidade da dificuldade que existe na sua tradução e, inclusive, na sua compreensão. Daí que as definições atribuídas ao conceito sejam muito distintas e variem consoante a formação teórica do autor/investigador. Pretende-se, a partir dessa identificação/compreensão, promover a qualidade de vida destas pessoas através do desenvolvimento de novas aprendizagens que possibilitem uma cooperação activa. É igualmente fundamental ir ao encontro das capacidade intactas de maneira a possibilitar a aquisição de novos(s) comportamento(s) que tenham um impacte positivo nas queixas, sinais, sintomas, incapacidade e disfuncionalidade apresentados pelo/a utente. Uma vez que a própria conceptualização do termo traduzirá aquilo que se pretende avaliar,será efectuada uma reflexão detalhada acerca dos instrumentos e definições que têm sido mais utilizadas para explorar o insight nas psicoses.Procurei, no meu trabalho de investigação, realçar e promover a importância que cada sujeito, alvo de intervenção, desempenha ao longo do seu processo de recuperação e na prevenção de recaídas. No seguimento dos objectivos acima descritos, para além da revisão teórica efectuada ao fenómeno em termos de conceptualização e estudos desenvolvidos na área de investigação, foi,neste estudo, realizada a contribuição para a validação do instrumento “Assessment of Insight in Psychosis: a re-standartization of a New Scale” de Marková & Berrios (2003).O fenómeno de insight escolhido pela Insight Scale, relata menos as mudanças vividas em relação à doença mental, e mais a actual consciência e articulação de tais mudanças. Tendo como base uma abordagem psicopedagógica, o fenómeno do insight aqui explorado assentou numa perspectiva reabilitativa, actual e multidimensional, que fosse para além das dimensões clínicas tradicionais. Neste sentido é apresentada uma escala original, intitulada “Escala de Avaliação do Insight e Identificação das Necessidades em Pessoas com Psicose”, bem como um modelo de intervenção psicopedagógico breve, assente nos pressupostos descritos ao longo do trabalho.-----------------------------------------ABSTRACT: The importance of insight in people with mental illnesses was first studied in psychiatry, in the first decades of the 20th century, by people as important as Lewis (1934) and Jaspers (1959). However, this field of investigation was left unexplored for many years. Only in the last decade has this phenomenon become the object of numerous scientific investigations, having been given special attention by its investigators. For this reason a significant number of instruments for evalauting insight in psychotic disorders were developed. Since then many papers have been published, which has allowed for a more in depth knowledge on the subject. Therefore, in recent years, the concept of insight has been developed in an attempt to clarify its compexity. A once dichotomic phenomenon, described in terms of presence or absence, became considered multidimensional, which made the identification of different levels of insight and different dimensions possible. Current concepts categorize insight into five dimensions: the awareness of the patient in relation to his/her mental illness, the awareness of the patient in relation to the social consequences of his/her illness, the awareness of the need for treatment, the awareness of the symptoms and the explanation of those symptoms in relation to the illness. The lack of insight in psychiatry, in general terms, and as this phenomenon has been described, the lack of awareness of having a mental illness, represents one of the most common symptoms of schizophrenia and affects a big part of the population that suffer from this illness. It is estimated that bewteen 50 and 80 per cent of patients with schizophrenia do not believe that they are ill, which, consequently has a big impact in the process of adherence to treatment. It is still not possible, however, to identify all the factors that determine the lack of insight in schizophrenics. There are psychological, social and cultural influences that almost certainly play their role in the lack of insight registered in this pathology.Since the impact of scizophrenia is felt in many aspects of the individual’s life, its effective treatment should be directed at various levels, including the improvement of insight. One of the objectives of this study is to explore the relationship between the level of insight in psychosis and the clinical and sociodemographic variables, the psychopathology and its global functioning. As well as the clinical and sociodemographic variables, there are of course important individual components that contribute to the level of insight seen in each patient, for example, their level of inteligence, personality, culture, past experiences, memory, etc. The clinical, emotional and/or intelectual nature of the term helps us understand the difficulty that lies in its interpretation as well as in its comprehension. Therefore, the definitions attributed to the term are very different and vary according to the theoretical training of the investigator. It is intended, from this identification/understanding, to promote the quality of life of these people through the development of new findings that might enable an active cooperation. It is equally fundamental to observe their unimpaired capacities in order to enable the acquisition of new behaviour(s) that have a positive impact on the complaints, signs, symptoms, incapacity and disfunctioning seen in the patient.As the actual comprehension of the term explains what we intend to evaluate, a detailed reflection is made on the instruments and definitions that have been used the most to explore insight in psychosis.In this investigation I tried to underline and promote the importance that each subject, undergoing medical intervention, plays during his/her process of recovery and prevention of relapses. Considering the above mentioned objectives, as well as a theoretical review of the phenomenon in terms of conceptualization and investigative studies developed, this study contributed to the validation of the instrument.The insight phenomenon chosen by the “Insight Scale”, records less changes experienced in relation to the mental illness and more actual awareness and articulation of these changes. Based on a psychopedagogical approach, the insight phenomenon explored here settled on a rehabilitation, current and multidimensional perspective that would go beyond the traditional clinical dimensions. For this reason an original scale entitled “Insight Evaluation Scale and Need Identification in Psychosis Patients” is presented, as well as a psychopedagogical intervention model soon to be used with admitted patients based on the presuppositions described in this study.

Changing representations and practices in school mathematics: the case of Modern Math in Portugal

The curricular movement known as Modern Mathematics aimed at the transformation of representations and practices in school mathematics. Its study provides us with ways of understanding how these changes came about. The purpose of this paper is to contribute to the understanding of the ways in which representations of school mathematics gradually were influenced by ideas from the Modern Mathematics movement, how these new ideas merged into local educational traditions, and how they were transformed into meaningful practice. This work is centred on the Portuguese context from the middle 1950s to the middle 1960s, and builds on Chervel’s notion of school culture and Gruzinski’s discussion of connected histories.

Fisioterapia : influência na qualidade de vida da mulher com cancro da mama : contributo para a qualidade do serviço em oncologia

RESUMO - O cancro da mama é uma preocupação da saúde pública a nível mundial, pela sua incidência, mortalidade e custos económicos associados. As terapias utilizadas no seu tratamento, embora eficazes, conduzem a alterações de todas as dimensões da Qualidade de Vida (QdV) da mulher com cancro da mama. A garantia de uma qualidade de serviço prestado deve ser uma prioridade das organizações de saúde, sendo a QdV uma medida de resultado. Partindo do pressuposto que em Portugal existe uma diferença potencial na forma como as mulheres com cancro da mama recebem o apoio por parte da fisioterapia, importa saber se a fisioterapia tem ou não influência na QdV da mulher com cancro da mama, o que, no caso de ser afirmativo, poderá constituir uma mais-valia para a qualidade do serviço prestado em oncologia. O Objectivo deste trabalho é construir um modelo de análise no sentido de responder à questão inicial de investigação: “Será que a fisioterapia contribui para a melhoria da Qualidade de Vida das mulheres com cancro da mama submetidas a cirurgia e outras terapias oncológicas?”. Neste sentido o trabalho de projecto dividiu-se por etapas. Inicialmente foi realizado um enquadramento teórico, através de uma revisão de literatura e da realização de entrevistas exploratórias, permitindo desta forma ter um conhecimento actual das temáticas que definem as variáveis e o objecto de estudo. Na etapa seguinte, foi feita uma análise crítica sobre o conhecimento actual do tema em estudo, que permitiu definir as variáveis a estudar, escolher o instrumento de medida a utilizar, ter conhecimento dos procedimentos a seguir. Após a definição do objectivo geral (avaliar se a fisioterapia tem influência na QdV das mulheres submetidas a cirurgia e outras terapias oncológicas) e dos objectivos específicos, iniciou-se o delineamento da metodologia tida como adequada para responder às questões de investigação levantadas (tipo de estudo, as variáveis, a unidade de análise, os métodos e técnicas de recolha de dados, os procedimentos e a metodologia de tratamento de dados). No âmbito do trabalho de projecto está definida a colocação em campo de um caso de estudo efectivo que permita dar um contributo real no delineamento da metodologia. Neste trabalho optou-se pela realização de um estudo piloto, que se enquadra nos procedimentos da metodologia e que teve por objectivo retirar algumas conclusões sobre: a aplicabilidade do instrumento de medida; os tempos definidos para a recolha de dados; as características sociodemográficas e clínicas da amostra; as questões de investigação levantadas. O estudo piloto consistiu num estudo pré-experimental, com uma amostra de 35 indivíduos, submetidos a cirurgia a cancro da mama e a outras terapias oncológicas. Foram avaliadas as dimensões do bem-estar físico e actividades quotidianas, bem-estar psicológico, relações sociais, sintomas e características sociodemográficas/clínicas, no início do tratamento individual de fisioterapia e no momento de alta. Utilizou-se como instrumento de medida o questionário EORTC QLQ–30 e o seu questionário complementar EORTC QLQ–23. Tendo sido construída uma ficha para recolha de dados sociodemográficos e clínicos. A significância estatística foi aceite para valores de p<0,05. Para comparação entre grupos e evolução dentro de cada grupo aplicou-se o teste t-student e o teste de Mann-Whitney. A análise dos resultados do estudo piloto permitiu verificar que: - O instrumento de medida proposto (questionário EORTC QLQ30 e BR23) mostrou ser de fácil aplicação, não tendo existido dificuldade por parte das doentes no seu preenchimento. Não houve problemas no cálculo dos scores e na sua interpretação; - Parte considerável das mulheres com cancro da mama será submetida a protocolos que se poderão prolongar por vários meses após a cirurgia (ex: QT+RT+HT). Esta realidade leva-nos a propor que sejam realizados vários momentos de avaliação, para que possam ser avaliadas as dimensões da QdV ao longo dos diferentes protocolos de tratamentos. Pensamos que o ideal seria a realização de 4 momentos de avaliação (3 a 4 semanas após a cirurgia, 3 meses, 6 meses e 9 meses após cirurgia). Sugerimos também que o estudo proposto seja realizado com uma amostra de maior dimensão; - O estudo piloto como recorreu a uma metodologia pré-experimental (ausência de grupo de controlo e apenas dois momentos de avaliação), não permite a consistência dos resultados; no entanto os resultados obtidos podem constituir um indicador de que a fisioterapia tem influência nas diferentes dimensões da QdV da mulher com cancro da mama submetida a cirurgia e a outras terapias oncológicas, podendo constituir uma mais-valia para a qualidade do serviço prestado em oncologia. Os resultados do estudo piloto permitiram redefinir a metodologia tida como adequada para responder à questão de investigação inicial. Apresentamos de seguida a mesma: Estudo quase-experimental, sendo a amostra constituída por dois grupos de 60 mulheres cada, submetidas a cirurgia a cancro da mama e a outras terapias oncológicas. O grupo experimental será submetido a tratamentos individuais de fisioterapia. Serão avaliadas as dimensões do bem-estar físico e actividades quotidianas, bem-estar psicológico, relações sociais e sintomas. A recolha de dados será realizada 3 semanas, 3 meses, 6 meses e 9 meses após a cirurgia. Como instrumento de medida será utilizado o questionário EORTC QLQ–30 e o seu questionário complementar EORTC QLQ–23, serão também recolhidos dados sociodemográficos e clínicos. A significância estatística será aceite para valores de p<0,05. Para comparação entre grupos e evolução dentro de cada grupo serão utilizados testes paramétricos e não paramétricos. A realização de um estudo que seguisse a metodologia acima referida permitiria uma maior consistência dos resultados, podendo eventualmente existir a confirmação de que a fisioterapia pode ter influência na QdV da mulher submetida a cirurgia a cancro da mama e a outras terapias oncológicas. A evidência de que a fisioterapia tem influência na QdV da mulher com cancro da mama, e o facto de a QdV ser um indicador da qualidade do serviço prestado em oncologia, poderão constituir um agente facilitador para a mudança na gestão de recursos humanos em organizações de saúde com a valência de oncologia, levando a uma alteração dos padrões de prática na área da fisioterapia em oncologia em Portugal, que poderá conduzir a uma melhor qualidade de serviço prestado ao doente oncológico. ----- ABSTRACT - Breast Cancer is a worldwide public health concern due to the incidence, mortality and economic costs associated. Although effective, therapies used in its treatment lead to changes in all Quality of Life (QoL) dimensions of a woman suffering from Breast Cancer. QoL is an outcome measure, and the insurance of quality of care provided should be a priority to health organizations. Taking into consideration that in Portugal there is a potential difference in the way women with Breast Cancer are provided with physical therapy, it is important to know whether physical therapy does or does not influence the QoL of women with breast cancer. If it does, it will lead to a health care quality improvement to cancer patients. The goal of the following study is to build an analysis model in order to answer the initial investigation question: “Does Physical Therapy contribute to enhance the Quality of Life of women with breast cancer who underwent surgery and other oncology treatments?” The project was divided in different stages. Initially, a literature revision was elaborated and exploratory interviews were held, which allowed an actual knowledge of the themes that define the variables and the object of study. The next stage included a critical analysis of the theme, which allowed the definition of variables of study, the choice of instrument of measure and the acquisition of some knowledge on how to proceed. After the definition of the general goal (to evaluate the influence of physical therapy on the QoL of women with breast cancer who underwent surgery and other oncology treatments) and specific goals, the choice of a right methodology took place, in order to answer the investigation questions (type of study, variables, unit analysis, methods and techniques on data collection, procedures and data treatment). In the scope of the project, it is decided to put out on the field an effective case-study which assures a real contribution on the choice of te methodology. In this particular work, there was a pilot study, included in the methodology procedures, with the goal of obtaining conclusions on the applicability of the instrument of measure; the length of time to collect data, the socio-demographic and clinical characteristics of the sample; the investigation questions. The pilot study consisted on a one group pretest-postest design, with a sample of 35 individuals who underwent surgery and other oncology treatments. Dimensions such as physical well-being and everyday life activities, psychological well-being, social relationships, symptoms and socio-demographical/clinical characteristics were assessed at the beginning of physical therapy individual treatment and at the moment of release. The instrument of measure used was the EORTC QLQ–30 questionnaire and its complementary questionnaire EORTC QLQ–23. A chart was made in order to collect socio-demographic and clinical data. Statistic significance was accepted for values of p<0,05. To compare between groups and to detect the evolution within each group, the t-student test and the Mann-Whitney test were applied. The outcome analysis of the pilot study allowed to verify that: - The instrument of measure proposed (EORTC QLQ30 and BR23) was easy to apply, and the subjects did not show any difficulty in filling it up. There was also no problem on calculating the scores or interpreting them; - A considerable part of the women with breast cancer will be submitted to protocols that may occur throughout several months after surgery (e.g., QT+RT+HT). This reality leads us to suggest several moments of assessment of the QoL dimensions in various moments of the different protocol treatments. We consider that the ideal number of evaluations would be 4 (3/4 weeks, 3 months, 6 months and 9 months after surgery). We also suggest the use of a larger sample; - Since the pilot study resorted to a one group pretest-postest design (there is an absence of control group and only two moments of assessment), there is no consistency of outcome. However, the results obtained indicate that physical therapy influences the dimensions of QoL on women with breast cancer who underwent surgery and other oncology treatments, which may be an asset to the quality of care provided to cancer patients. The outcome of the pilot study allowed to redefine the methodology given as adequate to answer the initial investigation question. Our suggestion is as follows: quasi-experimental design, with a sample of 120 subjects (2 groups of 60 women) with breast cancer who underwent surgery and other oncology treatments. The experimental group will be submitted to individual treatments of physical therapy. Dimensions such as physical well-being and everyday life activities, psychological well-being, social relationships and symptoms will be assessed. The collection of data will occur at 3 weeks, 3 months, 6 months and 9 months after surgery. The instrument of measure is the EORTC QLQ–30 questionnaire and its complementary questionnaire EORTC QLQ–23, and social-demographic and clinical information will also be collected. The statistic significance will be accepted for values of p<0,05. Parametric and non-parametric tests will be used to compare between groups and to detect the evolution within each group. Carrying out a study that followed the methodology discussed above would allow a better consistency of results, possibly enabling the confirmation that physical therapy influences the QoL of women with breast cancer who underwent surgery and other oncology treatments. The evidence that physical therapy influences the QoL of women with breast cancer, and the fact that QoL is an indicator of quality of care provided to cancer patients, may work as a facilitating agent in the change of human resources management in health organizations associated to oncology, which will lead to a change in oncology physical therapy practice patterns in Portugal, guiding to a health care quality improvement to cancer patients.
