RESUMO
Este estudo teve como objectivos a tradução e adaptação experimental da escala de queixas subjectivas de saúde (Eriksen, Ihlebaek, & Ursin, 1999), e a caracterização destas queixas na população portuguesa. A investigação desenvolveu-se em dois momentos: estudo piloto com 45 participantes e estudo definitivo com 1113 participantes. As correlações teste – re-teste são satisfatórias para a quase totalidade dos itens. Após a análise de componentes principais foi definida uma solução com 23 itens, distribuídos em cinco factores que explicam 50% da variância total. Os valores de consistência interna revelaram-se elevados nas sub-escalas e na escala total, quer no estudo piloto quer no definitivo. Estes resultados são congruentes com os encontrados pelos autores da escala original e sugerem que esta escala contribui para alargar o leque de variáveis que podem influenciar os comportamentos relacionados com a procura de cuidados de saúde da população portuguesa.
Palavras-chave: Queixas subjectivas de saúde, adaptação de escala, medida.
ABSTRACT
]]> The aim of this study was to develop a Portuguese version of the subjective health complaints scale (Eriksen, Ihlebaek, & Ursin, 1999), in order to study what is the nature and structure of these complaints in a Portuguese sample. The study was developed in two stages: (1) a pilot study with 45 participants and (2) a study with 1113 participants, recruited from different working environments across the country. The test-retest correlations are good for the majority of the items. The principal component analysis produced a 23-item solution in five factors, explaining 50% of the total variance. The internal consistency was high in all the subscales and in total scale, both in the pilot study and in the larger study. These results are consistent with those found by the authors of the original scale, and suggest that this measure will enhance the scope of variables that can influence health care behaviour of the Portuguese population.Key words: Subjective health complaints, scale adaptation, measure.
