Outcomes following stroke: social, psychological and physical factors predicting participation restriction. / 中風後的轉變: 社交參與局限性及其社交、心理及功能因素研究 / CUHK electronic theses & dissertations collection / Zhong feng hou de zhuan bian: she jiao can yu ju xian xing ji qi she jiao, xin li ji gong neng yin su yan jiuJanuary 2008 (has links)
A total of 188 patients completed data at twelve months (attrition rate: 29% over 12 months). The path coefficients show low functional ability (beta=0.51), more depressive symptoms (beta=-0.27), low state self-esteem (beta3=0.20), female gender (beta=0.13), older age (beta=-0.11) and living in a residential care facility (beta=-0.12) have a direct effect on participation restriction, and these variables accounted for 71% of the variance in explaining participation restrictions at 12 months. Repeated measures revealed significant decreases in overall levels of participation restriction and depressive symptoms from baseline to one year. However, no significant early changes in the levels of state self-esteem and depressive symptoms (from baseline to six months) and no significant late changes in both depressive symptoms and LHS scores were found (between six months and 12 months). / A total of 210 stroke survivors completed data at six months. Functional ability, state self-esteem, and number of strokes significantly accounted for 57% of the variance in participation restriction. Lower levels of functional ability, state self-esteem and social support satisfaction were associated with an increased likelihood of having depressive symptoms (z = 5.30, 34.12, and 5.51). / Aims. To gain understanding about the social, psychological and physical outcomes following inpatient stroke rehabilitation; to determine the variables predicting the level of participation and depressive symptoms of stroke survivors at baseline, six and 12 months following discharge from a rehabilitation hospital; to test a theoretical model of predictors of participation restriction at 12 months; and to determine the level over time for each of the outcomes. / Conclusion and implications. The findings in this study indicate that identification of stroke survivors at risk of high levels of participation restriction and low self-esteem will assist health professionals to devise appropriate interventions that target improving the psychological well being amongst person with stroke. Rehabilitation services need to continue to focus on restoring functional independence but also need to diagnose and treat depressive symptoms in order to minimise the restriction to participation in society. Assisting stroke survivors in redefining their identity after stroke could be an important aspect in stroke rehabilitation.

Validação da versão em português da entrevista telefônica para avaliação do estado cognitivo - modificada (TICS-M) em pacientes acometidos por acidente vascular cerebral / Validation of the portuguese version of the telephone interview for cognitive status - modified (tics-m) among post-stroke patientsBaccaro, Alessandra Fernandes 04 June 2014 (has links)
Introdução: O AVC (acidente vascular cerebral) é uma das mais importantes causas de alterações neuropsicológicas. Uma avaliação cognitiva inicial realizada por telefone implicaria em um diagnóstico mais precoce de prejuízo cognitivo e demência, reduzindo custos e tempo. Objetivo: Examinar as propriedades psicométricas da versão brasileira da Entrevista Telefônica para Avaliação do Estado Cognitivo - Modificada (TICS-M) em pacientes pós-AVC. Métodos: Previamente à validação da TICS-M em indivíduos acometidos por AVC, foi realizada tradução para o Português do Brasil e adaptação transcultural da versão original da TICS-M em uma amostra de 30 sujeitos não clínicos. Após esta fase, um subgrupo de 61 pacientes com AVC, participantes do Estudo da Mortalidade e Morbidade do AVC (EMMA) que ocorre no Hospital Universitário da Universidade de São Paulo, foram convidados a participar da validação da TICS-M, seis meses após o evento agudo. A TICS-M foi aplicada em três momentos: avaliação inicial (entrevista presencial), uma e duas semanas após a primeira avaliação. Na avaliação inicial, além da TICS-M, questionários adicionais foram aplicados para avaliar a cognição: MoCA (Montreal Cognitive Assessment), MEEM (Mini Exame do Estado Mental); e para a depressão, HDRS (Hamilton Depression Rating Scale). Todos os questionários foram aplicados por duas entrevistadoras treinadas para o estudo. A confiabilidade intra-observador da TICS-M foi testada através dos coeficientes de Pearson, Intraclasse e alfa de Cronbach. As características internas do TICS-M também foram avaliadas através de uma análise exploratória utilizando o método Análise de Componentes Principais. A validade discriminatória do instrumento para rastreamento de demência pós-AVC foi avaliada em comparação a MEEM pela análise da área sob a curva (AUC) determinada pela curva ROC. Foram calculadas sensibilidade e especificidade para o ponto de corte ideal para rastrear demência. Resultados: De maneira geral, a TICS-M traduzida para o português apresentou um bom entendimento dos itens na mostra de indivíduos não clínicos. Foi observada uma frequência de 23% sugestiva de demência pós-AVC. O nível de escolaridade esteve positivamente associado ao estado demencial rastreado pelo MEEM. O estado depressivo assim como outras características de base não se associou à demência sugerida pelo MEEM. A confiabilidade teste-reteste intra-observador revelou taxas quase totais nos três momentos avaliados (Pearson Coeficiente > 0,85, Coeficientes de Correlação Intraclasse > 0,85 e Coeficiente alfa de Cronbach: 0,96). A análise fatorial determinou três domínios: memória de trabalho e atenção; memória recente e de evocação e orientação. A área sob a curva (AUC) determinada para a TICS-M em comparação com MEEM foi de 0,89 (intervalo de confiança 95%: 0,80-0,98). O ponto de corte sugerido para TICS-M foi de 14 pontos (escala de 0-39 pontos) para rastrear demência com sensibilidade de 91,5% e especificidade de 71,4%. Resultados semelhantes foram observadas com o MoCA. Conclusão: A versão brasileira da TICS-M sugere ser um instrumento de pesquisa útil e confiável para rastrear demência em pacientes pós-AVC / Introduction: Stroke is one most important cause of neuropsychological disorders. An initial cognitive assessment performed by telephone resulting in an early diagnosis of cognitive impairment and dementia, reducing costs and time. Objective: To examine the psychometric properties of the Brazilian version of the Modified Telephone Interview for Cognitive Status Assessment (TICS-M) for assessment of dementia in post-stroke patients. Methods: Prior to validation of TICS-M in post-stroke patients, translation was performed for the Brazilian-Portuguese and cross-cultural adaptation of the original version of TICS-M in a non-clinical sample of 30 subjects. After this phase, 61 stroke patients enrolled in the Stroke Mortality and Morbidity Study (The EMMA study) that occurs at the University Hospital of the University of São Paulo, were invited to participate in this sub-study to validate the TICS-M six months after the acute event. The TICS-M was applied in three moments: first evaluation (personal interview), one and two weeks after of the first evaluation. At the first evaluation, beyond the TICS-M, additional questionnaires were applied to assess cognition: MoCA (Montreal Cognitive Assessment), MMSE (Mini-Mental Status Examination), and for depression, HDRS (Hamilton Depression Rating Scale). All questionnaires were administered by two trained interviewers for the study. Reliability of the TICS-M was tested by intra-observer rates using Pearson, Intraclass and Cronbach´s alpha coefficients. The internal characteristics of TICS-M were also evaluated by an exploratory analysis using Principal Component Analysis. The discrimination validity of the instrument to assess dementia was evaluated by comparison to the MMSE analysis of the area under the curve (AUC) determined by the ROC curve. Sensitivity and specificity for the ideal cutoff to assess dementia were calculated. Results: In general, the TICS-M translated into Portuguese version showed a good understanding of the items in non-clinical individuals. A frequency of 23% suggestive of post-stroke dementia was observed. The level of education was positively associated with dementia status assessed by MMSE. The depressive status, as well as, other baseline characteristics was not associated with dementia suggested by MMSE. Test-retest reliability intra-observer revealed almost total rates in the three evaluation moments (Pearson coefficient > 0.85, Intraclass Correlation Coefficient > 0.85 and Cronbach\'s alpha coefficient: 0.96). The factorial analysis determined three domains: working memory and attention, recent and recall memory and orientation. The area under the curve (AUC) determined by TICS-M compared to MMSE was 0.89 (95% confidence interval: 0.80-0.98). The cutoff suggested for TICS-M was equal or greater than 14 points (range 0-39 points) to assess dementia (91.5% sensitivity, 71.4 % specificity). Similar results were observed with the MoCA. Conclusion: The Brazilian version of TICSM suggests being a useful and reliable research instrument to evaluate dementia in poststroke patients in epidemiological studies
