Talking everyday science to very young children: a study involving parents and practitioners within an early childhood centre

The acquisition of everyday scientific concepts by 3-6 year old children attending early childhood institutions has been widely studied. In contrast, research on science learning processes among younger children is less extensive. This paper reports on findings from an exploratory empirical study undertaken in a ‘stay and play’ service used by parents with children aged 0-3 and located within an East London early childhood centre. The research team collaborated with practitioners to deliver a programme of activities aimed at encouraging parents’ confidence in their own ability to support emergent scientific thinking among their young children. The programme generated children’s engagement and interest. Parents and practitioners reported increased confidence in their ability to promote young children’s natural curiosity at home and in early childhood provision. The authors see no reason for positing qualitative differences between the way children acquire scientific and other concepts in their earliest years.

Pytanie o pamięć. Relacje autobiograficzne więźniów obozów koncentracyjnych

This book consists of two main parts. The first part offers a basic methodological introduction, presenting a concise but multifaceted overview of current problems of collective memory. The second part contains a set of interviews with former prisoners of concentration camps carried out by the authors. The research was conducted by Paweł Greń and Łukasz Posłuszny and focuses on issues of collective and cultural memory illustrated by individual life experiences of concentration camps prisoners. The field of oral history serves as the framework of analysis and narrative inquiry as its research tool. Interviews and additional research materials were collected by the authors and are not available in previous publications, making this work a precious supplement to the current scholarly body of knowledge and achievements in the discipline of memory studies. According to the authors, current historical and literary publications provide an incomplete picture of the WWII and its aftermaths for survivors, because descriptions of the war and imprisonment in the camp play still a dominate role in narratives. The importance of these issues in autobiographies is unquestionable and highly needed to create a common identity among generation of prisoners, though authors often wanted to perceive the fate of individuals in a broader perspective – including the periods before and after the war. Hence, interviews stressed personal experiences and their understanding over time by former prisoners. The interviews covered many topics on life before, during and after the camp – among them daily and neutral routines, but also difficult matters. The latter were connected on the one hand with traumatic events or harsh memories and emotions, and on the other hand with less extensively highlighted threads of prisoners’ lives - such as issues of the body and sexuality – and their dependence on particular representation or narrative. The authors are convinced that the book serves not only as a record of past remembered by eyewitnesses, but it also depicts their accounts in wider contexts and discourses, which expose specific dimensions of told and written stories. In the book Questions for Memory one examine the approach proposed by young scholars. Interviews were conducted from 2009-2011, seventy years after the end of the second world war, and this initiative was the result of questions and doubts of the authors from the existing literature. They also wanted to use the unique opportunity to meet with eyewitnesses and record their stories, because when they pass away we will irretrievably lose the possibility to listen to them and to pose sensitive questions. The majority of the interviewees were prisoners of KL Auschwitz-Birkenau, and their experiences differed greatly from each other based on social background and specific experience in the camps as well as their post-camp and postwar life. Aside from persons whose stories are already well known and open, readers will hear the stories of those who spoke only reluctantly and very rarely, or who had remained silent until the present author’s research. Qualitative differences between interviews occurred on the level of established relationship and atmosphere of trust, which varied according to circumstances and individual character and personality. For P. Greń and Ł. Posłuszny, each interviewed person is equally and highly valued due to the collected material and the personal experience of the meetings. Among the ten interviews placed in the book, seven of them are the stories told by women. Their testimonies exemplify realities of everyday prisoners’ existence and gravitate towards mirroring specifically feminine perspectives of imprisonment. For women, crucial problems stemmed from experiences of body that intertwine with suffering, feeling of shame and humiliation. Early discussions on holocaust literature and issues of representation that shaped the Polish narrative and collective memory imposed imperatives of silence on certain topics. A solution for reconciling heroic and inhuman deeds in stories with completely human physiology was impossible and improper for many years. There were also questions about life after, ways of dealing with a trauma or reflections on the present time. During conversations the authors attempted to come closer to something distant and incomprehensible for their generation and for people who did not experience the camps. Despite the fact that there have been seventy years of dealing with these events in literature, art, drama, film, memoirs and scientific works, the past still breeds more questions than answers. The book Questions for Memory serves as an example of this phenomenon.

Comparison of five popular normalization methods using a spike-in proteomics data set

Mass spectrometry (MS)-based proteomics has seen significant technical advances during the past two decades and mass spectrometry has become a central tool in many biosciences. Despite the popularity of MS-based methods, the handling of the systematic non-biological variation in the data remains a common problem. This biasing variation can result from several sources ranging from sample handling to differences caused by the instrumentation. Normalization is the procedure which aims to account for this biasing variation and make samples comparable. Many normalization methods commonly used in proteomics have been adapted from the DNA-microarray world. Studies comparing normalization methods with proteomics data sets using some variability measures exist. However, a more thorough comparison looking at the quantitative and qualitative differences of the performance of the different normalization methods and at their ability in preserving the true differential expression signal of proteins, is lacking. In this thesis, several popular and widely used normalization methods (the Linear regression normalization, Local regression normalization, Variance stabilizing normalization, Quantile-normalization, Median central tendency normalization and also variants of some of the forementioned methods), representing different strategies in normalization are being compared and evaluated with a benchmark spike-in proteomics data set. The normalization methods are evaluated in several ways. The performance of the normalization methods is evaluated qualitatively and quantitatively on a global scale and in pairwise comparisons of sample groups. In addition, it is investigated, whether performing the normalization globally on the whole data or pairwise for the comparison pairs examined, affects the performance of the normalization method in normalizing the data and preserving the true differential expression signal. In this thesis, both major and minor differences in the performance of the different normalization methods were found. Also, the way in which the normalization was performed (global normalization of the whole data or pairwise normalization of the comparison pair) affected the performance of some of the methods in pairwise comparisons. Differences among variants of the same methods were also observed.

TGA/FTIR study of the pyrolysis of diammonium hydrogen phosphate–tobacco mixtures

Diammonium hydrogen phosphate (DAP) is commonly used as a flavor ingredient of commercial cigarettes. In addition, among its other uses, it is employed to expand the tobacco volume, to manufacture reconstituted tobacco sheet, and to denicotinize tobacco. However, the use of DAP as a cigarette ingredient is a controversial issue. Some authors have stated that ammonium compounds added to tobacco increase smoke ammonia and “smoke pH”, resulting in more free nicotine available in the smoke. On the other hand, other researchers have reported that the larger ammonium content of a cigarette blend due to the presence of DAP was not reflected in increased smoke ammonia. In this work, the thermal behavior of DAP, tobacco and DAP-tobacco mixtures has been studied by TGA/FTIR. The chemical processes involved in the different pyrolysis steps of DAP have been suggested. Marked changes in the pyrolytic behavior of both, tobacco and DAP have been detected when analyzing the behavior of the mixtures. A displacement of the decomposition steps mainly related to the glycerol and lignin from tobacco toward lower temperatures has been observed, whereas that associated with cellulose is displaced toward higher temperature. Additionally, no peak corresponding to the phosphorous oxides decomposition has been detected in the curves relating to the DAP-tobacco mixtures. All these features are indicative of the strong interactions between DAP and tobacco. The FTIR spectra show no significant qualitative differences between the qualitative overall composition of the gases evolved from the pyrolysis of tobacco in the absence and in the presence of DAP. Nevertheless, depending on the temperature considered, the addition of DAP contributes to a decrease in the generation of hydrocarbons and an increase in the formation of CO, CO2 and oxygenated compounds in terms of amount generated per mass of pyrolysed tobacco.

Causes of communication problems at work: A qualitative analysis of supervisor-subordinate differences

This study provided information about how individual workers perceive, describe and interpret episodes of problematic communication. Sixteen full-time workers (5 males, 11 females) were interviewed in depth about specific incidents of problematic communication within their workplace. Their descriptions of the attributed causes of the incidents were coded using a categorisation scheme developed from Coupland, Wieman, and Giles' (1991) model of sources of problematic communication. Communication problems were most commonly attributed to individual deficiency and group membership, although there were differences depending on the direction of communication. The most negative attributions (to personality flaws, to lack of skills, and to negative stereotypes of the outgroup) were most commonly applied by individuals to their supervisors, whilst attributions applied to co-workers and subordinates tended to be less negative, or even positive in some instances (where individuals attributed the fault to themselves). Overall, results highlighted distinctions between the perceptions of communication problems with supervisors and with subordinates, and are interpreted with reference to social identity theory.

The analysis of foreign market entry strategies on the basis of different cultural backgrounds and environments: a qualitative study characterising the differences and similarities of Brazilian and European firms

Moving into a new and foreign market can be challenging, especially when such market has a different culture and working environment in comparison to the home market. Thus, it is of utter importance to adjust a company’s strategy to the new market conditions. Currently, there are no concrete guidelines of what aspects are most important when moving from a developing market such as Brazil into a more sophisticated market like Europe, or vice versa. The present study will examine two companies from the same industry, but with different cultural backgrounds and its strategic similarities and differences for operating in multiple international markets. The data was collected via semi-structured interviews with the Chief Executive Officers (CEOs’) from both companies, using an interview guideline that is based on three different theoretical frameworks. The aim is to give recommendations to these two industries of how to efficiently use existing theoretical frameworks and which aspects are most significant when moving into a new market while keeping in mind a company’s size and background.

Patients’ action during their cardiac event: qualitative study exploring differences and modifiable factors

Objectives: To explore the circumstances and factors that explain variations in response to a cardiac event and to identify potentially modifiable factors.

Dysmorphogenesis in psychosis: Quantitative and qualitative measures involving the head and face

In this study, we examined qualitative and quantitative measures involving the head and face in a sample of patients and well controls drawn from the Brisbane Psychosis Study. Patients with psychosis (n=310) and age and sex-matched controls (n=303) were drawn from a defined catchment area. Features assessed involved hair whorls (position, number, and direction), eyes (epicanthus), supraorbital ridge, ears (low set, protrusion, hypoplasia, ear lobe attachment, asymmetry, helix width), and mouth (palate height and shape, palate ridges, furrowed and bifid tongue). Quantitative measures related to skull size (circumference, width and length) selected facial heights and depths. The impact of selected risk factors (place and season of birth, fathers' occupation at time of birth, selfreported pregnancy and birth complications, family history) were examined in the entire group, while the association between age of onset and dysmorphology was assessed within the patient group. Significant group (cases versus controls) differences included: patients had smaller skull bases, smaller facial heights, larger facial depths, lower set and protruding ears, different palate shape and fewer palate ridges. In the entire sample significant associations included: (a) those with positive family history of mental illness bad smaller head circumference, cranial length and facial heights; (b) pregnancy and birth complications was associated with smaller facial beights: (c) larger head circumference was associated with higher ranked fathers' occupations at birth. Within the patient group, age of onset was significantly lower in those with more qualitative anomalies or with larger facial heights. The group differences were not due to outliers or distinct subgroups, suggesting that the factors responsible for the differences may be subtle and widely dispersed in the patient group. The Stanley Foundation supported this project.

Neutrophil depletion increases susceptibility to systemic and vaginal candidiasis in mice, and reveals differences between brain and kidney in mechanisms of host resistance

Infections caused by the yeast Candida albicans represent an increasing threat to debilitated and immunosuppressed patients, and neutropenia is an important risk factor. Monoclonal antibody depletion of neutrophils in mice was used to study the role of these cells in host resistance. Ablation of neutrophils increased susceptibility to both systemic and vaginal challenge. The fungal burden in the kidney increased threefold on day 1, and 100-fold on day 4, and infection was associated with extensive tissue destruction. However, a striking feature of the disseminated disease in neutrophil-depleted animals was the altered pattern of organ involvement. The brain, which is one of the primary target organs in normal mice, was little affected. There was a threefold increase in the number of organisms recovered from the brains of neutrophil-depleted mice on day 4 after infection, but detectable abscesses were rare. In contrast, the heart, which in normal mice shows only minor lesions, developed severe tissue damage following neutrophil depletion. Mice deficient in C5 demonstrated both qualitative and quantitative increases in the severity of infection after neutrophil depletion when compared with C5-sufficient strains. The results are interpreted as reflecting organ-specific differences in the mechanisms of host resistance.

Quantitative and qualitative comparison of 3.0 T and 1.5 T MR imaging of the liver in patients with diffuse parenchymal liver disease

Purpose: The purpose of our study was to compare signal characteristics and image qualities of MR imaging at 3.0 T and 1.5 T in patients with diffuse parenchymal liver disease. Materials and methods: 25 consecutive patients with diffuse parenchymal liver disease underwent abdominal MR imaging at both 3.0 T and 1.5 T within a 6-month interval. A retrospective study was conducted to obtain quantitative and qualitative data from both 3.0 T and 1.5 T MRI. Quantitative image analysis was performed by measuring the signal-to-noise ratios (SNRs) and the contrast-to-noise ratios (CNRs) by the Students t-test. Qualitative image analysis was assessed by grading each sequence on a 3- and 4-point scale, regarding the presence of artifacts and image quality, respectively. Statistical analysis consisted of the Wilcoxon signed-rank test. Results: the mean SNRs and CNRs of the liver parenchyma and the portal vein were significantly higher at 3.0 T than at 1.5 T on portal and equilibrium phases of volumetric interpolated breath-hold examination (VIBE) images (P < 0.05). The mean SNRs were significantly higher at 3.0 T than at 1.5 T on T1-weighted spoiled gradient echo (SGE) images (P < 0.05). However, there were no significantly differences on T2-weighted short-inversion-time inversion recovery (STIR) images. Overall image qualities of the 1.5 T noncontrast T1- and T2-weighted sequences were significantly better than 3.0 T (P < 0.01). In contrast, overall image quality of the 3.0 T post-gadolinium VIBE sequence was significantly better than 1.5 T (P< 0.01). Conclusions: MR imaging of post-gadolinium VIBE sequence at 3.0 T has quantitative and qualitative advantages of evaluating for diffuse parenchymal liver disease. (C) 2008 Elsevier Ireland Ltd.

The importance of qualitative methodology in management empirical research

Purpose: The aim of this paper is to highlight the importance of qualitative research within the scope of management scientific studies, referring to its philosophy, nature and instruments. It also confronts it with quantitative methodology, approaching its differences as well as its complementariness and synergies, with the purpose of explaining, from a more analytic point of view, the relevance of qualitative methodology in the course of an authentic and real research despite its complexity. Design/methodology/approach: Regardless of its broad application, one may attest the scarcity literature that focuses on qualitative research applied to the management scientific area, as opposed to the large amount that refers to quantitative research. Findings: The paper shows the influence that qualitative research has on management scientific research. Originality/value:. Qualitative research assumes an important role within qualitative research by allowing for the study and analysis of certain types of phenomena that occur inside organisations, and in respect of which quantitative studies cannot provide an answer.

Differences in internet and LMS usage: a case study in higher education

The Internet plays an important role in higher education institutions where Learning Management Systems (LMS) occupies a main role in the eLearning realm. In this chapter we aim to characterize the Internet and LMS usage patterns and their role in the largest Portuguese Polytechnic Institute. The usage patterns were analyzed in two components: characterization of Internet usage and the role of Internet and LMS in education. Using a quantitative approach, the data analysis describes the differences between gender, age and scientific fields. The carried qualitative analysis allows a better understanding of students’ both motivations, opinions and suggestions of improvement. The outcome of this work is the presentation of the Portuguese students’ profile regarding Internet and LMS usage patterns. We expect that these results can be used to select the most suitable digital pedagogical processes and tools to be adopted regarding the learning process and most adequate LMS’s policies.

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.
