Abstract(s)
Introdução: O Questionnaire on Everyday Navigational Ability (QuENA), originalmente desenvolvido para sujeitos com doença de Alzheimer, consiste num questionário de rápida aplicação que pretende avaliar e diferenciar sintomatologia de desorientação topográfica (DT) através de quatro subescalas intituladas: Agnosia de pontos de referência, desorientação egocêntrica, desatenção e desorientação de encaminhamento. Esta avaliação é essencial no contexto das doenças neurodegenerativas e vasculares devido ao impacto que estas capacidades têm na vida dos doentes. No entanto à data atual, o QuENA não se encontra validado para a população portuguesa. Objetivo: Fazer uma validação do questionário numa amostra da população portuguesa e estudar as propriedades psicométricas do QuENA nesta população. Métodos: Foi realizado um estudo transversal com uma amostra de participantes saudáveis da população portuguesa (n=123). Os participantes foram avaliados através de uma bateria de testes cognitivos e provas relacionadas com capacidades de orientação topográfica: Mini-Mental State Examination (MMSE); Escala de Queixas Subjetivas de Memória (QSM); QuENA; Wayfinding Questionnaire (WQ); Teste de Imagética Topográfica (TIT); Teste de conhecimento Topográfico (TCT); Teste de Localização Topográfica (TLT). Resultados: O QuENA apresentou uma consistência interna aceitável quanto à sua pontuação total ( a de Cronbach =0,705), mas não quanto às suas 4 subescalas. Concomitantemente, verificou-se apenas um ajuste aceitável segundo modelo unidimensional quanto à validade de constructo. O total do QuENA revelou uma moderada fiabilidade no coeficiente correlação intraclasse (CCI=0,561) e uma correlação de Pearson moderada (r=0,406) no teste-reteste. Não se verificou qualquer influência direta da idade, género e escolaridade ao nível do score total do QuENA, tal como não se verificaram correlações significativas com os totais do MMSE, TCT, TIT e TLT. Apenas a subescala de orientação espacial do MMSE demonstrou ser preditora do score total do QuENA (Beta=-0,182, p=0,05) após uma análise de regressão linear. Verificou-se também, uma correlação significativa entre o total do QuENA e os totais do WQ (R=-0,397, p=0,000) e QSM (R=0,343, p=0,000). Conclusão: Embora a amostra testada seja relativamente pequena e haja propriedades psicométricas que não foram atingidas, o instrumento revelou algumas qualidades apropriadas e uma relação interessante com algumas capacidades cognitivas e perceção subjetiva da cognição, sugerindo que a sua validação numa amostra mais extensa e diversificada poderá ser relevante como mais uma escala de avaliação neuropsicológica
Introduction: The Questionnaire on Everyday Navigational Ability (QuENA), originally developed for subjects with Alzheimer's disease, consists of a quick application questionnaire which aims to assess and differentiate topographical disorientation (DT) symptoms through four subscales entitled: landmark and scene agnosia, egocentric disorientation, inattention and heading disorientation. This assessment is essential in the context of neurodegenerative and vascular diseases due to the impact that these skills have on patients' lives. However, no validation studies were conducted with QuENA for the Portuguese population. Objective: To validate the questionnaire in a sample within the Portuguese population and study the psychometric properties of QuENA in this population. Methods: A cross-sectional study was carried out with a sample of healthy participants from the Portuguese population (n = 123). Participants were assessed using a compilation of cognitive tests and tests related to topographic orientation skills: Mini-Mental State Examination (MMSE); Subjective Memory Complaints Questionnaire (SMCQ); QuENA; Wayfinding Questionnaire (WQ); Topographic Imagery Test (TIT); Topographic Knowledge Test (TKT); Topographic Location Test (TLT). Results: QuENA presented an acceptable internal consistency in terms of its total score (Cronbach a= 0.705), but not in terms of its 4 subscales. Concomitantly, there was only an acceptable fit for a one-dimensional model regarding the construct validity. The total score of QuENA revealed a moderate reliability in the intraclass correlation coefficient (ICC = 0.561) and a moderate Pearson correlation (r = 0.406) in the test-retest. There was no influence of age, gender and education at the level of the total QuENA score, just as there were no significant correlations with the totals of the MMSE, TCT, TIT and TKT. Only the subscale of spatial orientation of the MMSE proved to be a predictor of the total QuENA score (Beta= -0.182, p=0.05) after a linear regression analysis. There was also a significant correlation between the total of QuENA and the totals of WQ (R= -0.397, p=0.000) and SMCQ (R = 0.343, p= 0.000). Conclusion: Although the tested sample is relatively small and there are psychometric properties that have not been reached, this tool revealed some appropriate qualities and an interesting relationship with some cognitive abilities and subjective perception of cognition, suggesting that its validation in a more extensive and diverse sample, may be relevant as yet another neuropsychological assessment scale
