RESUMO
OBJETIVO: Avaliar os diferentes instrumentos de medida usados em pacientes com fibromialgia. PACIENTES E MÉTODOS: Foram avaliados 60 indivíduos que participaram de um ensaio clínico de corte transversal comparando os efeitos de exercícios realizados na água e exercícios realizados em solo, por meio dos questionários Fibromyalgia Impact Questionnaire (FIQ) para avaliar o impacto da doença, The Medical Outcomes Study 36 item Short-Form Health Survey (SF-36) para avaliação da qualidade de vida, Inventário Beck para avaliar o estado de depressão e escala visual analógica da dor (EVA). Esses questionários foram comparados aos resultados obtidos em uma escala transicional do tipo Likert, a Escala verbal de avaliação de mudança (EVAM), considerada como critério de mudança na avaliação dos outros instrumentos. RESULTADOS: O coeficiente de Spearman foi usado para estudar a correlação entre a medida EVAM e os outros instrumentos em dois momentos (T1 e T2). Em T1 houve correlação moderada entre EVAM e EVA (r = 0,49), EVAM e FIQ (r = 0,41) e correlação negativa entre EVAM e os domínios referentes a dor (r = -0,49), estado geral (r = -0,55) e componente físico (r = -0,42) do SF-36. Em T2, apenas o domínio vitalidade do SF-36 mostrou correlação negativa com EVAM, de valor fraco (r = -0,27). CONCLUSÃO: Considerando-se a EVAM como padrão ouro, nenhum dos instrumentos avaliados conseguiu captar, de maneira ótima, mudança no estado de saúde do paciente com fibromialgia.
ABSTRACT
OBJECTIVE: To assess the different measure instruments used for patients with fibromyalgia. PATIENTS AND METHODS: This study assessed 60 individuals participating in a clinical trial of cross-sectional cohort comparing the effects of exercises performed in water and on land. The following instruments were used: the Fibromyalgia Impact Questionnaire (FIQ) to assess the impact of the disease; the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) to assess quality of life; the Beck Depression Inventory to assess depression; and the Visual Analogue Scale (VAS) of pain. Those questionnaires were compared with the results obtained in a transitional Likert-type scale, the verbal scale for assessing change (VSAC), considered as a criterion of change in the assessment of other instruments. RESULTS: The Spearman coefficient was used to study the correlation between the VSAC measure and the other instruments at two occasions (T1 and T2). At T1, a moderate correlation was observed between VSAC and VAS (r = 0.49), and between VSAC and FIQ (r = 0.41), and a negative correlation was observed between VSAC and the SF-36 domains pain (r = -0.49) and general health perception (r = -0.55), and the SF-36 physical component (r = -0.42). At T2, only the SF-36 domain vitality showed a weak negative correlation with VSAC (r = -0.27). CONCLUSION: Considering VSAC as gold standard, none of the instruments assessed could optimally identify a change in the health status of patients with fibromyalgia.
