ABSTRACT
A síndrome fibromiálgica (SFM) é uma síndrome dolorosa, de etiologia desconhecida, com alta prevalência e frequentes condições associadas, que causa grande impacto no cotidiano e na qualidade de vida dos pacientes. OBJETIVO: Verificar, devido ao seu caráter multifatorial, o poder discriminativo dos instrumentos, a fim de identificar indicadores que permitam expressar a autoavaliação e o autoconhecimento. PACIENTES E MÉTODOS: Trata-se de um estudo descritivo, exploratório, comparativo, de corte transversal e amostra de um grupo-teste (T), com diagnóstico de SFM (n = 63), e de um grupo-controle (C) submetido a interconsulta na Clínica da Dor (n = 75). Os instrumentos utilizados foram: Questionário de Impacto de Fibromialgia (FIQ), Escala Visual Analógica (EVA), Questionário de Dor McGill e o Protocolo Pós-Sono (PSI). Para avaliar a qualidade de vida, foi utilizado Questionário SF-12. RESULTADOS: Na amostra dos dois grupos houve predomínio do gênero feminino, média de idade de 42,3 ± 4,3 anos, 45 por cento casados e média de escolaridade de 8 ± 3,5 anos. Foi relatado um tempo médio de dor de 3,2 anos e uma média de dois anos para o diagnóstico de SFM no grupo T. O grupo T apresentou níveis mais altos de dor, ansiedade e depressão, pior qualidade de sono, menos flexibilidade e pior qualidade de vida, embora alguns desses sintomas também estejam presentes entre os indivíduos do grupo C. CONCLUSÃO: Todos os instrumentos têm poder discriminativo (P < 0,05), destacando FIQ, EAV e PSI, que produziram maior área sob a curva (AUC) ROC.
Fibromyalgia syndrome (FMS) is a painful condition of unknown etiology, highly prevalent, and associated with other conditions, which causes great impact on daily life and quality of life. OBJECTIVE: To assess, due to the multifactorial character of the FMS, the discriminating power of instruments used to identify good indicators of self-assessment and self-knowledge. PATIENTS AND METHODS: This is a descriptive, exploratory, comparative, cross-sectional study with quantitative approach, and sample comprising a treatment group (T), diagnosed with FMS (n = 63) and a control group (C), undergoing interconsultation at the Pain Outpatient Clinic (n = 75). The following instruments were used: Fibromyalgia Impact Questionnaire (FIQ); visual analogue scale (VAS); McGill Pain Questionnaire; and the Post-Sleep Inventory (PSI). To evaluate the quality of life, Medical Outcomes Study 12-item Short-Form Health Survey (SF-12) was used. RESULTS: In the two groups, female gender predominated. The mean age of the sample was 42.3 ± 4.3 years, 45 percent were married, and the average schooling was 8 ± 3.5 years. The mean duration of pain was 3.2 years, and a mean time of two years were required for the clinical diagnosis of FMS in group T. Group T had higher levels of pain, anxiety, and depression, worse quality of sleep, less flexibility, and worse quality of life, although some of these symptoms were also present in group C. CONCLUSIONS: All instruments had good discriminating power (P < 0.05), especially FIQ, VAS and PSI, whose areas under the ROC curve were greater.
