          Abstract

          Objetivou-se investigar a validade de construto e a consistência interna da Escala de Autoestima de Rosenberg (RSES) (1965) para idosos brasileiros. Participaram 292 idosos (67.54; DP = 6.90 anos) praticantes de atividades físicas na cidade de Florianópolis, Santa Catarina, Brasil. Para analisar a validade de construto, realizou-se a análise fatorial, descrita em duas etapas: a análise dos componentes principais e a análise dos pesos fatoriais. Após, procedeu-se à rotação oblíqua, por meio do método Oblimin. Para verificar a consistência interna da escala, utilizou-se o coeficiente alfa de Cronbach. Observou-se a existência de dois fatores, que, juntos, explicaram 51% da variância total dos resultados da escala. O primeiro desses fatores sozinho explicou 38% dessa variância e o segundo por apenas 13.4% da mesma. A análise fatorial sem rotação indicou que a escala pode ser considerada unidimensional. No entanto, após a rotação, verificou-se que os itens negativos constituem o primeiro fator e os positivos o segundo fator. O alfa de Cronbach verificado foi de 0.812, considerado bom. Observou-se que a RSES apresentou qualidades psicométricas aceitáveis para a pesquisa com idosos brasileiros praticantes de atividades físicas, desta forma, pode ser considerado um instrumento válido e confiável para ser utilizado com essa população.

          The present research aimed at investigating the construct validity and reliability of the Rosenberg’s Self-esteem Scale (RSES) (1965) for Brazilian older adults. 292 elderly participants (67.54, DP = 6.90 years) who do physical activities in Florianopolis, Santa Catarina, Brazil. The analysis of the data was made in two steps: the analysis of the principal components and analysis of the factor loadings. To examine the construct validity we carried out the factor analysis described in two stages: principal component analysis and factor weights. After, we proceeded with the oblique rotation, using the method Oblimin. To check the reliability of the scale, we used the Cronbach’s alpha. It was observed that there were two factors that together accounted for 51% of the total variance of the results of the scale. The first of these factors solely explained for 38% of the variance, and the second by only 13.4% of the variance. The factor analysis without rotation indicated that the scale can be considered one-dimensional. However, after the rotation, it was found that the negatives are the first factor and the second positive factor. Cronbach’s alpha was established 0,812, considered good. It was observed that the RSES had acceptable psychometric qualities for research on Brazilian elderly who practice physical activities, thus can be considered a valid and reliable instrument for use with this population.

            Positive and negative global self-esteem: a substantively meaningful distinction or artifactors?

            Global self-esteem based on M. Rosenberg's (1965) scale is typically treated as a unidimensional scale. However, factor analyses suggest separate factors associated with positively and negatively worded items, and there is an ongoing debate about the substantive meaningfulness of this distinction. Confirmatory factor analysis (CFA) was used to evaluate alternative 1- and 2-factor models and to test hypotheses about how the factors vary with reading ability and age. Responses based on the National Longitudinal Study of 1988 (S.J. Ingles et al., 1992) reflected a relatively unidimensional factor and method effects associated with negatively worded items. Such effects are common in rating scale responses, and this CFA approach may be useful in evaluating whether factors associated with positively and negatively worded items are substantively meaningful or artifactors.
