Tese no âmbito do Doutoramento em Psicologia, especialidade em Psicologia Clínica apresentada à Faculdade de Psicologia e Ciências de Educação da Universidade de Coimbra. The administration of neurophysiological, neurocognitive and behavioral measures as endophenotypes in studies about schizophrenia is in vogue, particularly the inquiry on their interrelationships and their impact on patient’s functional outcome. To this date, increasingly large Portuguese samples with genetic risk to schizophrenia (patients and families) have been integrated into studies about candidate genes to schizophrenia or linkage studies relating schizophrenia to other severe mental illnesses. The inclusion of Portuguese samples gained significant interest for being genetically homogenous in comparison to other western populations. However, despite cognitive abilities being also largely inheritable and relevant to the understanding of schizophrenia, the profile of cognitive deficits in schizophrenia has not been sufficiently explored in our national samples. The use of neurocognitive assessment in schizophrenia has the potential to yield innovations in the multidisciplinary treatment and intervention for affected patients and families, and future research that heighten our understanding about what stands between the genotype and the phenotype regarding this complex and impairing disease. The work hereby presented provides an empirical contribute to the understanding of the endophenotypic aspects involved in schizophrenia, and to the discussion of the implications to research, new intervention targets and psychosocial approaches for families and patients. We studied several putative neurocognitive endophenotypes of that illness by developing an in-depth investigation of the neurocognitive and social cognition in schizophrenia in Portuguese samples of patients affected with schizophrenia, first-degree relatives, and controls. We dove below the cloudy waters of clinical heterogeneity of symptoms to attempt to provide a characterization of schizophrenia – both on an endophenotypic and functional level – in an objective and comprehensive approach. By empirically tracing a latent neurocognitive profile and characterizing the underlying processes of the clinical and biological underpinnings of schizophrenia, we expected to contribute to a more coherent systematization of schizophrenia and treatment/rehabilitation. As a by-product of this research, we also aimed to provide specific and psychometrically sound tools for neurocognitive assessment and performance-based skills assessment relevant to practitioners and researchers working in several disciplinary fields with Portuguese-speaking populations. A administração de medidas neurofisiológicas, neurocognitivas e comportamentais para a avaliação de variáveis endofenotípicas nos estudos sobre a esquizofrenia é uma área que tem adquirido um progressivo destaque, particularmente no que toca o questionamento sobre as inter-relações entre estas variáveis e o seu impacto na capacidade funcional dos doentes. Até a data, diversos estudos sobre genes candidatos à esquizofrenia ou estudos de ligação relacionando a esquizofrenia a outras doenças mentais graves integraram grandes amostras portuguesas de sujeitos em risco genético para esquizofrenia (pacientes e famílias). A inclusão destas amostras relaciona-se com o facto da população portuguesa ser geneticamente mais homogénea em comparação com outras populações ocidentais. No entanto, e apesar das capacidades cognitivas serem, em grande parte, também hereditárias e relevantes para a compreensão da esquizofrenia, o perfil dos défices cognitivos na esquizofrenia não tem sido suficientemente explorado em amostras nacionais. O uso da avaliação neurocognitiva na esquizofrenia tem o potencial de introduzir inovação no tratamento e potenciar intervenções multidisciplinares direcionadas para pacientes e famílias afetadas, bem como o potencial de fomentar futuras investigações orientadas para o aumento da nossa compreensão sobre o que existe entre o genótipo e o fenótipo desta doença tão complexa e invalidante. O trabalho aqui apresentado é um contributo para a compreensão dos aspetos endofenotípicos subjacentes à esquizofrenia, bem como para a discussão das suas implicações para a investigação, para o estabelecimento de alvos específicos de intervenção e para o desenvolvimento abordagens psicossociais específicas para famílias e pacientes que sofrem de esquizofrenia. Estudámos diversos endofenótipos neurocognitivos putativos da doença, encontrados na literatura, desenvolvendo uma investigação aprofundada da neurocognição e da cognição social na esquizofrenia, em amostras portuguesas de pacientes diagnosticados com esquizofrenia, parentes em primeiro grau e controlos. Mergulhámos para além das águas conturbadas pela heterogeneidade clínica dos sintomas para tentar proporcionar uma caracterização da esquizofrenia – tanto ao nível endofenotípico quanto funcional – recorrendo a abordagens objetivas e metodologicamente abrangentes. Ao traçar empiricamente um perfil neurocognitivo latente e ao caracterizar os processos clínicos e biológicos subjacentes da esquizofrenia, esperámos poder contribuir para uma futura sistematização mais coerente da esquizofrenia, bem como para o seu tratamento e reabilitação. Como um subproduto deste trabalho, procurámos, ainda, fornecer ferramentas específicas e psicometricamente robustas para a avaliação neurocognitiva e para a avaliação de habilidades baseadas no desempenho, que se mostrassem relevantes para profissionais e investigadores atuantes em diversas áreas disciplinares junto de populações falantes da língua portuguesa.

Emotional management (EM) is a crucial skill for achieving relevant biopsychosocial goals, and there has been an increased demand for the effective measurement of EM ability. The current study aimed to explore the psychometric properties of the Portuguese version of the brief Situational Test of Emotional Management (STEM-B) using the item response theory in a sample of 899 participants. The global fit indicated the model had a good adjustment, with most items aligning vertically across the logit scale and presenting an adequate range of item difficulty and fit. Differential item functioning analysis showed no differences in difficulty between genders, but some items differed according to the education level and age-groups. Overall, findings suggest the STEM-B is a psychometrically sound measure for specific testing of EM skills that has the potential to be used across cultures and fields. [ABSTRACT FROM AUTHOR]

ICAP 2015: 17th International Conference on Applied Psychology. Tokyo, Japan, May 28-29, 2015. The aim of the current study was to develop and validate a Response to Stressful Situations Scale (RSSS) for the Portuguese population. This scale assesses the degree of stress experienced in scenarios that can constitute positive, negative and more neutral stressors, and also describes the physiological, emotional and behavioral reactions to those events according to their intensity. These scenario include typical stressor scenarios relevant to patients with schizophrenia, which are currently absent from most scale, assessing specific risks that these stressors may bring on subjects, which may prove useful in nonclinical and clinical populations (i.e. patients with mood or anxiety disorders, schizophrenia). Results from Principal Components Analysis and Confirmatory Factor Analysis of on two adult samples from general population allowed to confirm a three-factor model with good fit indices: χ2 (144)= 370.211, p = 0.000; GFI = 0.928; CFI = 0.927; TLI = 0.914, RMSEA = 0.055, P( rmsea ≤ 0.005) = 0.096; PCFI = 0.781. Further data analysis on the scale revealed that RSSS is an adequate assessment tool of stress response in adults to be used in further research and clinical settings, with good psychometric characteristics, adequate divergent and convergent validity, good temporal stability and high internal consistency. info:eu-repo/semantics/publishedVersion

The current focus on community integration of individuals with psychiatric problems is attracting an increasing interest in the psychological literature, as it is regarded as a favorable factor in the recovery and for the well-being of these individuals. The Community Integration Scale of Adults with Psychiatric Disorders (CIS-APP-34) is a self-report scale developed to assess community integration in several dimensions. The main goal of the current study is to explore the psychometric properties of CIS-APP-34 in a sample of 411 participants with and without a psychiatric illness, with ages between 19 and 91 years old, living in the Azores Islands, Portugal. A confirmatory factor analysis was carried out to confirm the latent structure of the scale, and a five-factor model has presented good fit indices. Further analysis showed that the CIS-APP-34 is a measure with good reliability, validity and discriminant ability. [ABSTRACT FROM AUTHOR]

Background Paranoid ideation has been regarded as a cognitive and a social process used as a defence against perceived threats. According to this perspective, paranoid ideation can be understood as a process extending across the normal-pathological continuum. Methods In order to refine the construct of paranoid ideation and to validate a measure of paranoia, 906 Portuguese participants from the general population and 91 patients were administered the General Paranoia Scale ( GPS), and two conceptual models (one- and tridimensional) were compared through confirmatory factor analysis ( CFA). Results Results from the CFA of the GPS confirmed a different model than the one-dimensional model proposed by Fenigstein and Vanable, which comprised three dimensions (mistrust thoughts, persecutory ideas, and self-deprecation). This alternative model presented a better fit and increased sensitivity when compared with the one-dimensional model. Further data analysis of the scale revealed that the GPS is an adequate assessment tool for adults, with good psychometric characteristics and high internal consistency. Conclusion The model proposed in the current work leads to further refinements and enrichment of the construct of paranoia in different populations, allowing the assessment of three dimensions of paranoia and the risk of clinical paranoia in a single measure for the general population.

Several studies about stigmatization and shame toward mental health problems have contributed to minimizing the impact of these negative attitudes on people diagnosed with mental illnesses, on their families and on their communities. The Attitudes Towards Mental Health Problems Scale (ATMHP) is a self-report scale aimed at the assessment of attitudes toward mental health that involve several factors relating to attitudes and shame (internal, external, and reflected shame) when facing mental health problems. The goal of the current study was to translate, and to adapt this scale to the Portuguese population, and to study its psychometric properties in a sample of Azorean adults with and without psychiatric problems. The scale was administered to 411 participants with ages between 19 and 81 years. Confirmatory factor analysis was carried out on the initial model proposed by the authors of the ATMHP, and results showed a poor adjustment. An alternative model comprising an additional factor was tested and presented good model fit indices. Based on the alternative model, further analysis revealed that the scale has good psychometric properties. [ABSTRACT FROM AUTHOR]
