Adaptation and validation of the dispositional hope scale for adolescents/Adaptacao e validacao da escala de esperanca disposicional para adolescentes

This paper describes the psychometric features and the validation process of the Adult Dispositional Hope Scale (ADHS) for adolescents in the south of Brazil. This scale measures the Hope construct in terms of pathways and agency. The ADHS was translated to Portuguese and underwent a reverse translation. A sample of 450 students, from 14 to 18 years old (M=16.8 years, SD=3.4, 56% female), answered the ADHS, the Hope Index, the LOT-R and the Rosenberg's Self-Esteem Scale. A factorial analysis with varimax rotation showed that the scale is unidimensional and that its internal consistency was adequate (Cronbach's alpha = .80). No significant gender differences were found. Correlations of ADHS with the other constructs presented evidence of convergent validity in the present study. Keywords: Dispositional Hope Scale, hope, positive psychology. Este trabalho descreve o processo de validacao e caracteristicas psicometricas da Adult Dispositional Hope Scale (ADHS) para adolescentes do sul do Brasil. Esta escala avalia o construto Esperanca em termos de rotas e agenciamento. A ADHS foi traduzida para o portugues e submetida a uma traducao reversa.

A analise fatorial com rotacao varimax mostrou que o instrumento e unidimensional e que sua consistencia interna e adequada (Alfa de Cronbach=0,80. Nao foram encontradas diferencas entre os generos. As correlacoes da ADHS com outros construtos conferem evidencias de validade convergente ao estudo. Palavras-chave: Dispositional Hope Scale (ADHS), esperanca, psicologia positiva.
