Abstract in Portuguese
A crença de auto-eficácia relaciona-se com a percepção da dor e com a funcionalidade física e psíquica dos doentes. Os objetivos deste estudo foram validar para a língua portuguesa a escala Chronic Pain Self-efficacy Scale e analisar as crenças de auto-eficácia de doentes com dor crônica. A amostra foi de 132 pacientes com dor crônica de etiologia variada (54,5% fibromialgia e 24,2% dor neuropática); 87,9% foram mulheres, a idade média foi de 46 anos (DP=12,6) e a escolaridade média de 10,1 anos. A média da intensidade da dor foi de 6,83 (DP=2,3) e o tempo médio de dor foi de 7,4 anos (DP=7,7). A validade da escala em língua portuguesa foi confirmada pela análise fatorial, que manteve os 3 domínios e os 22 itens da escala original; a variância explicada foi de 60,8%. A confiabilidade, analisada pelo alfa de Cronbach, variou entre 0,76 e 0,92 para os domínios e foi de 0,94 para a escala total. A validade convergente, verificada por meio da comparação entre os escores da Escala de Auto-Eficácia para Dor Crônica (AEDC) e os escores do Inventário de Depressão de Beck mostrou correlação negativa e estatisticamente significativa. As crenças de auto-eficácia foram analisadas em relação às variáveis sexo, idade, escolaridade, renda, intensidade da dor e tempo de dor. As variáveis escolaridade e intensidade da dor apresentaram associação com a auto-eficácia. Doentes com menor escolaridade relataram menor auto-eficácia, e naqueles com dor menos intensa, observou-se maior auto- eficácia. Este estudo disponibiliza para a língua portuguesa um instrumento válido e confiável para avaliar a auto-eficácia de pacientes com dor crônica. A validade da escala AEDC foi confirmada pela análise fatorial, análise da consistência interna e validade convergente.

Abstract in English
The self-efficacy belief, relate to the pain perception and physical and psychiatric functionality. The goals of this study were to validate to the Portuguese language the Chronic Pain Self-efficacy Scale (CPSS) and analyze the self-efficacy beliefs of chronic pain patients. The subjects were 132 chronic pain patients with pain from diverse etiology (54,5% fibromyalgia, 24,2% neuropatic pain), 87,9% were women, the middle age were 46 years (SD=12,6) and educational level was 10,1 years. The pain intensity were 6,83 (SD=2,3) and the median time of pain were 7,4 years (SD=7,7). The scale validity in the Portuguese language was confirmed by factor analyzis, which maintained the 3 factors and 22 items of the original scale; the accounted variance was 60,8%. The reliability, analyzed by coefficient Cronbach´s alpha were 0,76 - 0,92 to the factors and 0,94 to the total scale. The convergent validity, verified by the comparison with the Escala de Auto-Eficácia para Dor Crônica (AEDC) scores and Beck Depression Inventory (BDI) scores showed significantly negative correlation. The self-efficacy beliefs were analyzed related to sex, age, educational level, income, pain intensity and pain chronicity. The educational level and pain intensity were related with self-efficacy. Subjects with lower educational level reported lower self-efficacy levels and those ones with lower pain levels, reported higher self-efficacy. This study became available to the Portuguese language a valid and reliable instrument to assess self-efficacy in chronic pain patients. The scale (AEDC) validity was confirmed by factor analyzis, internal consistency and convergent validity.
