Validação e aplicação clínica de uma escala de cognição social na esquizofrenia = Validation and clinical use of a measure of social cognition in schizophrenia

RESUMO: A cognição social encontra-se frequentemente alterada na esquizofrenia. Esta alteração relaciona-se com a diminuição do funcionamento social,caracterizando-se quer por défices quer por vieses cognitivos sociais. No entanto, existem poucos instrumentos fiáveis e válidos para avaliar a cognição social na esquizofrenia, nomeadamente capazes de medir os vieses cognitivos sociais e a cognição social auto-relevante. Adicionalmente, as bases biológicas da disfunção social não estão totalmente esclarecidas. Evidências recentes sugerem que o peptídeo oxitocina (OXT) influencia o funcionamento social, e que esta relação poderá ser mediada pela cognição social. Este Trabalho de Projecto descreve a contribuição do autor para o desenvolvimento e avaliação psicométrica inicial de um novo instrumento de avaliação da cognição social, e a utilidade desta escala na investigação das associações entre a OXT e a capacidade e vieses cognitivos sociais. A Waiting Room Task (WRT), uma escala constituída por 26 vídeos sequenciais que simulam a experiência de observar outra pessoa numa sala de espera, foi administrada num estudo transversal com 61 doentes com esquizofrenia e 20 controlos saudáveis. Observou-se uma menor capacidade cognitiva social e um aumento dos vieses cognitivos sociais nos doentes com esquizofrenia, comparativamente aos controlos. Nos controlos e doentes com delírios, o desempenho na WRT correlacionou-se significativamente com os níveis de OXT. Esta correlação não se observou nos doentes sem delírios, sugerindo que o papel da OXT na cognição social poderá encontrar-se atenuado neste grupo. Estes achados fornecem suporte inicial para a adequação da WRT como instrumento de avaliação da cognição social na esquizofrenia, podendo ainda ser útil na investigação da sua base biológica. ------------ ABSTRACT: Social cognition is often impaired in schizophrenia. This impairment is related to poor social functioning and is characterized by both social cognitive deficits and biases. However, there are few reliable and valid measures of social cognition in schizophrenia, particularly measures of social cognitive bias and of self-relevant social cognition. Also, the biological bases of social dysfunction are not well understood. Emerging evidence suggests that the peptide oxytocin (OXT) influences social functioning, and that this relationship may be mediated by social cognition. This Research Project describes the author’s contribution to the development and initial psychometric testing of a new measure of social cognition, and the utility of this instrument to examine associations between OXT and social cognitive capacity and bias. The Waiting Room Task WRT), a video-based test comprising 26 sequential videos simulating the experience of facing another person in a waiting room, was administered in a cross-sectional study involving 61 patients with schizophrenia and 20 healthy controls. Social cognitive capacity was lower and social cognitive bias was increased in patients with schizophrenia compared with controls. Among controls and patients with delusions, performance on the WRT was significantly correlated with OXT level. This correlation was not found in patients without delusions suggesting that OXT’s role in social cognition may be blunted in this group. These findings provide initial support for the adequacy of the WRT as a measure for assessing social cognition in schizophrenia that may also be useful in understanding its biological underpinnings.

Development of population-specific function assessment intrument in Lebanon

RESUMO: Contexto: O funcionamento tem sido reconhecido como um dos principais indicadores de resultados para avaliar se as pessoas beneficiam das intervenções destinadas a melhorar a sua saúde mental. O funcionamento refere-se à forma como um indivíduo consegue responder às suas tarefas e solicitações, dos seus familiares e da sua comunidade, de acordo com os requisitos do local e a cultura em que vive (eg, tarefa de cozinhar e limpar para as mulheres em algumas culturas ). O funcionamento é altamente dependente da cultura - por isso, tem sido recomendado o desenvolvimento de medidas de funcionamento específicas de cada cultura. Desenvolver localmente os instrumentos de medida evita problemas de adequação, associados com a adaptação de instrumentos ocidentais. Embora os instrumentos criados desta forma sejam específicos de um meio cultural, eles são simultaneamente "transculturais", no sentido em que cada um se refere às tarefas mais importantes para a população local . Esta abordagem mostrou-se útil para investigadores e agências de ajuda (eg, ONGs) que trabalham em países não-ocidentais . Este estudo descreve o trabalho da agência International Medical Corps (IMC) na criação e validação de um questionário de funcionamento específico nas dimensões cultura e gênero, no Líbano, destinado a avaliar eventuais melhorias em pessoas que receberam intervenções de para problemas de saúde mental, a nível dos cuidados primários de saúde. Método: O instrumento foi desenvolvido usando um método que é uma alternativa à abordagem existente de adaptação de instrumentos ocidentais a outras culturas e situações; esta abordagem é rápida e exequível, tendo já demonstrado ser útil no desenvolvimento de instrumentos válidos e fidedignos. Inicialmente, foi solicitado que as pessoas identificassem, de uma lista livre, as tarefas mais importantes para cuidar de si próprias, da sua família e da sua comunidade; as tarefas identificadas foram posteriormente usadas como base para um instrumento de avaliação de funcionamento culturalmente válido. A partir daqui, foram desenvolvidos questionários específicos da comunidade em questão, posteriormente testados no terreno nas vertentes da validade (de conteúdo, facial e de constructo) e da fiabilidade (teste-reste e inter-entrevistadores). Resultados. O estudo resultou na criação e validação de um questionário de funcionamento específico de cultura e gênero capaz de medir efectivamente a capacidade de execução de tarefas importantes do quotidiano,como parte da avaliação de resultados levada a cabo por profissionais da CSP previamente treinados na identificação, suporte e encaminhamento de pessoas com problemas de saúde mental no Líbano. Conclusão. Neste trabalho descreve-se o desenvolvimento de um questionário de funcionamento específico de cultura e gênero, orientado para a avaliação de resultados, num contexto mais lato de um sistema abrangente de avaliação e monitorização de um serviço comunitário. --------------ABSTRACT: Background. Functioning has been recognized as one of the most important key outcomes to assess whether people benefit from interventions aimed to improve their mental health. Functioning refers to how well na individual can complete the tasks and demands for themselves, their family, and their community which are required by them depending on the setting and the culture they live in (e.g. task of cooking and cleaning for women in some cultures). Functioning is highly dependent on culture. Therefore, it has been recommended to develop culture-specific measures of function. Developing instruments locally avoids the problems of limited local relevance and appropriateness associate with adapting western instruments. Although each instrument created in this way is culturally bound, they are “cross cultural” in the sense that each refers to the tasks most important to local people. This approach proves useful for both researchers and aid agencies working in non-western countries. This study describes International Medical Corps’ (IMC) work in Lebanon to create and validate a culture and gender specific functioning questionnaire to assess improvements in people who received treatment interventions for mental health problems at the primary health care (PHC) level. Method. The measure was developed using a method that is an alternative to the existing approach of adapting western function instruments to other cultures and situations; an approach which has been demonstrated as rapid, feasible and which can yield valid and reliable instruments. Function was assessed by first asking local people what tasks are important to care for themselves, their family and their community using free listing, then using these tasks as the basis for a culturally valid function assessment instrument. Community specific function questionnaires based on these tasks were then created, and field-tested for validity using content, face and construct validity methods, and also field tested for reliability using inter-rater and test retest reliability methods. Results. The study resulted in the creation and validation of a culture and gender specific functioning questionnaire that would effectively measure the ability to do tasks important to daily existence, as part of assessing client level outcomes where PHC providers were trained in the identification, management and referral of people with mental health problems in Lebanon. Conclusion. The paper describes a successful pilot for developing culture and gender specific functioning questionnaires that evaluate client level outcomes as part of a more comprehensive system for monitoring and evaluation of community based case management supports and services.

Identifying the urban communities of New York City using bikeshare data from NYC citibike

This study identifies a measure of the cultural importance of an area within a city. It does so by making use of origindestination trip data and the bike stations of the bike share system in New York City as a proxy to study the city. Rarely is movement in the city studied at such a small scale. The change in strength of the similarity of movement between each station is studied. It is the first study to provide this measure of importance for every point in the system. This measure is then related to the characteristics which make for vibrant city communities, namely highly mixed land use types. It reveals that the spatial pattern of important areas remains constant over differing time periods. Communities are then characterised by the land uses surrounding these stations with high measures of importance. Finally it identifies the areas of global cultural importance alongside the areas of local importance to the city.

To what extent do aspects of sustainability impact established firms' resilience

An organizations´ level of sustainability has so far been primarily been analyzed within the context of economic performance. This study changes that dependent variable to “resilience”, namely a company’s ability to recover from potential lethal shocks or disruptive events. The research questions aims to investigate whether sustainability and resilience are related. This study utilizes the financial crisis from 2007/08 as disruptive event, as it encompassed market phase-out but also survival by established firms. Two Swiss luxury watchmaking companies have been chosen as industry sample and the study’s investigation is based on a comparative case study approach. The latter applies both quantitative data, in the form of the respective annual company reports, and qualitative data, in the form of semi-structured interviews with three stakeholder groups. Findings indicate that the investigated measures of sustainability are related the investigated companies’ level of resilience. These findings contribute to the building of new theory towards resilience as this study outlines specifically which measures have been proven to be of relevance for companies’ resilience. Moreover, the results are of high relevance for companies that are operating in constant evolving markets and struggling adapting to any disruptive environment as it is outlined why and how comparative companies have to be sustainable in order to become more resilient towards future shocks.

The impact of job insecurity on adaptive performance via burnout

Difficult and unpredictable times, due to economic instability, lead employees to feel high job insecurity. Organizations’ only way to subsistence is to search innovative ways of solving problems and find creative solutions. This study focuses on the impact that job insecurity has on adaptive performance, a recent measure integrating the response of creativity, reactivity in the face of emergencies, interpersonal adaptability, training effort, and handling work stress, and, mediated by burnout. From the responses of two questionnaires (????????1=252; ????????2=145), we conclude that job insecurity leads to exhaustion, but not to disengagement. In turn, it is the latter that demonstrates to have negative relations with some measures of adaptive performance. Thus, it is crucial to understand how organizations can minimize the inherent process.

Millennium BCP: Optimization of the branches closure process

Nowadays, a significant number of banks in Portugal are facing a bank-branch restructuring problem, and Millennium BCP is not an exception. The closure of branches is a major component of profit maximization through the reduction in operational and personnel costs but also an opportunity to approach the idea of “baking of future” and start thinking on the benefits of the digital era. This dissertation centers on a current high-impact organizational problem addressed by the company and consists in a proposal of optimization to the model that Millennium BCP uses. Even though measures of performance are usually considered the most important elements in evaluating the viability of branches, there is evidence suggesting that other general factors can be important to assess branch potential, such as the influx on branches, business dimensions of a branch and its location, which will be addressed in this project.
