RESUMO

O presente estudo descreve a adaptação para uma amostra portuguesa da Escala de Auto-Eficácia relativa à Diabetes (SEDS) - (Grossnman, Brink & Hauser, 1987). Esta escala está baseada na teoria da auto-eficácia de Bandura e pretende avaliar as percepções pessoais relativas à competência, capacidades e meios para os adolescentes lidarem adequadamente com a diabetes.

A amostra do nosso estudo é composta por 175 adolescentes provenientes do Serviço de Endocrinologia do Hospital S. João, no Porto. A escala composta por 35 itens agrupados em 3 sub escalas foi submetida a uma análise das suas propriedades psicométricas na amostra portuguesa seguindo uma metodologia semelhante aos autores originais.

A versão portuguesa apresenta um alfa global de .90. Os alfas para as sub escalas: auto-eficácia em situações médicas, auto-eficácia em situações gerais e auto-eficácia face ao tratamento da Diabetes são respectivamente de: .62., .63 e .87. A versão final da escala ficou reduzida a 30 itens. Os itens estão agrupados em 3 componentes tal como na versão original: auto-eficácia relativa ao tratamento, auto-eficácia social, e confiança.

Palavras-chave: Diabetes, auto-eficácia, adolescentes.

 

 

ABSTRACT

This study describes the adaptation of the Self efficacy Diabetes Scale (SEDS) (Grossman, Brink & Hauser, 1987) in a Portuguese sample. This scale is based in self-efficacy theory of Bandura and intends to assess personal perceptions towards competency, skills and means for adolescents to manage diabetes.

The sample in our study is composed by 175 adolescents from the Endocrinology Service in S. John´s Hospital in Oporto. The scale with 35 items grouped in three subscales, was assessed in terms of its psychometric properties following a methodology similar to the original authors.

The Portuguese version shows an alpha of .90. The alphas for the subscales: self efficacy in medical situations, self-efficacy in general situations and self-efficacy towards treatment of diabetes are respectively: .62, .63, and .87. The final version was reduced to 30 items. The items are grouped in three components as the original version: self-efficacy towards treatment, social self-efficacy and trust.

Key words: Diabetes, self-efficacy, adolescents.
