Abstract(s)
O presente estudo visa a validação da escala psicométrica de resiliência desenvolvida por Wagnild & Young para a população portuguesa a partir da validação preliminar desenvolvida por Vara e Sani (2006). A escala a validar é composta por 25 afirmações que requerem o posicionamento do inquirido entre 7 pontos da escala de Likert. A validação psicométrica do questionário de resiliência de Wagnild & Young desenvolveu-se a partir da Análise Fatorial Exploratória onde foram identificadas as dimensões mais significativas que a escala apresenta através do estudo da confiabilidade e da Análise Fatorial Confirmatória. Utilizando uma amostra de 313 inquiridos, analisou-se a confiabilidade da escala e a validação do construto obteve-se a partir da análise fatorial, utilizando o coeficiente Alpha de Cronbach para avaliação da consistência interna da escala. Determinaram-se como fatores: satisfação com a vida (F1), planificação-disciplina (F2) e independência (F3) e verificou-se uma correlação média positiva entre os 3 fatores. A análise fatorial confirmatória apresentou valores ótimos de índice de ajuste Comparativo (.988) e da Raíz da Média dos Quadrados dos Erros de Aproximação (.025), pelo que concluímos que estamos perante um ótimo ajuste ao modelo. Globalmente, os valores dos principais indicadores globais de ajustamento do modelo resultantes da análise fatorial confirmatória expressam a sua qualidade. Como valores de consistência interna dos três fatores recorreu-se ao coeficiente de Alpha de Cronbach obtendo-se os valores ótimos de .798 (escala geral), .747 no fator 1 «satisfação com a vida», .712 no fator 2 «planificação – disciplina» e .632 no fator 3 «independência».
The present study aims to validate the psychometric scale resilience developed by Wagnild & Young for the Portuguese population from the preliminary validation developed by Vara and Sani (2006). The scale consists of 25 validate assertions that require the placement of respondent between 7 points Likert scale. Psychometric validation of the resiliency Wagnild & Young questionnaire was developed from the exploratory factor analysis where the most significant dimensions that scale features through the study of reliability and confirmatory factor analysis were identified. Using a sample of 313 respondents, we analyzed the scale reliability and construct validation was obtained from the factor analysis, using Cronbach’s alpha coefficient for internal consistency of the scale. Were determined as factors: satisfaction with life (F1),planning discipline (F2) and independence (F3) and there was a positive correlation between the average three factors. Confirmatory factor analysis showed excellent index values Comparative (.988) adjustment and the Root Mean Squares of Errors of Approximation (.025), so we conclude that this is an optimal fit to the model. Overall, the values of the key indicators of overall fit of the model resulting from the confirmatory factor analysis to express its quality. As internal consistency of the three factors we used the coefficient of Cronbach Alpha obtaining the optimal values of .798 (overall scale), .747 on Factor 1 “satisfaction with life”,.712 on factor 2 “planning - discipline “and .632 in factor 3 ‘independence’.
