- Estudo de validação do questionário de avaliação da sobrecarga para cuidadores informaisPublication . Martins, Teresa; Ribeiro, José Luís Pais; Garrett, CarolinaO Questionário de Avaliação da Sobrecarga do Cuidador Informal (QASC)I é um instrumento construído para avaliar a sobrecarga física, emocional e social do cuidador informal (CI) de doentes com sequelas de AVC. O presente estudo descreve a construção e a determinação das características psicométricas deste instrumento. Através de uma amostra de conveniência foram estudados 210 CI e respectivos familiares alvo dos cuidados. Na maioria, estes CI eram do sexo feminino (88,1%), filhas ou esposas. Os sujeitos alvo dos cuidados (52,2% do sexo masculino) apresentavam dependência funcional em pelo menos uma actividade básica da vida diária, ou duas actividades instrumentais. Através da Análise de Componentes Principais, foram discriminados 7 factores, que explicam 59% da variância total: implicações na vida pessoal do CI; satisfação com o papel e com o familiar; reacção a exigências; sobrecarga emocional; suporte familiar; sobrecarga financeira e mecanismos de eficácia e de controlo. O QASCI apresenta uma boa consistência interna em 6 dos seus componentes (valores superiores a 0,70). ------ ABSTRACT ------ The Questionário de Avaliação da Sobrecarga do Cuidador Informal (QASCI) is a scale to assess stroke caregiver’s physical, emotional and social strain. The present study describes the construction of the scale and the validation results. Through a convenience sample, 210 caregivers and their stroke relative’s were studied. Most of these caregivers were female (88,1%), daughters or wives. The stroke survivors (52,2% are males) had functional dependence an at least a daily life basic activity, or two instrumental activities. Through the Principal Components Analysis, 7 factors were discriminated, that explain 59% of the total variance: implications in the personal life of caregiver; satisfaction with the paper and with the relative; reactions to demands; emotional overload; support family; financial overload and mechanisms of effectiveness and control. QASCI presented good reliability in 6 of their components (Cronbach’s alpha>0,70).
- Within an between-year winter-site fidelity of Chiffchaffs Phylloscopus collybitaPublication . Catry, Paulo; Catry, Inês; Catry, Teresa; Martins, TeresaCurrent knowledge concerning between-year winter site fidelity in passerines suggests there might be important inter-specific and regional variations in recurrence rates (the proportion of birds recaptured in years subsequent to marking). However, there are virtually no studies reporting low recurrence rates that show this not to be simply the result of low recapture probabilities. This problem can be particularly acute for partly nomadic and mostly non-territorial species in their winter quarters. The present study shows that, in spite of the apparently nomadic behaviour of wintering Chiffchaffs Phylloscopus collybita, some individuals can become temporarily sedentary. Temporarily sedentary Chiffchaffs have very small linear home-ranges (ca. 200m) and their calculated recapture probability (by re-sighting of colour-ringed birds) is high. In spite of that, recurrence rate of temporarily sedentary birds is very low, suggesting that the majority of the surviving individuals are not site faithful. This is in contrast to what has been found in several detailed studies in other Sylviidae and also Parulidae involving mostly territorial birds. The type of approach developed here should be used in other studies before any comparisons and generalisations involving winter-site fidelity results are attempted.
