In gout there are few instruments validated for the evaluation of activity, functional capacity, or quality of life. It is not known if generic instruments such as the MOS-20, or specific for other illnesses, such as the AIMS, can be applied to patients with gout.

To evaluate the clinimetric characteristic of the MOS-20 and AIMS questionnaires, and their correlation with HAQ-DI, as well as with clinical variables in patients with tophaceous gout (TG).

Fortyy-nine patients with TG were included. Demographic and clinical variables were obtained. The 3 questionnaires were applied at the basal evaluation. A second evaluation was applied to 20 patients, 8 weeks later.

All patients were male. The time of since onset of the illness was 14.9 (8.3) years. The HAQ-DI was 0.43 (0.56) with an alpha of Cronbach (αC) of 0.95 and the intraclass correlation coefficient (ICC) was 0.86. The MOS-20 had an αC of 0.68 to 1.0 and a ICC of 0.27 to 0.61 between the several components. The AIMS had an αC of 0.66 to 0.96, and a ICC of 0.11 to 0.79 between the several components. Reliability was better between the physical components in MOS-20 and AIMS. The MOS-20, AIMS and the HAQ-DI correlated with the presence of joints with functional limitation. There weren’t any significant differences among the patients with inflamed joints, nor in those with tophi. The HAQ-DI was best correlated with the physical component than with the mental component of the AIMS and the MOS-20.

The AIMS, the MOS-20 and the HAQ-DI are useful in measuring the functional capacity and the quality of life in patients with TG.

Hay pocos instrumentos en el estudio de gota validados para evaluar la actividad, la capacidad funcional o la calidad de vida de los pacientes. Se desconoce si los instrumentos genéricos como el cuestionario MOS-20 (Medical Outcomes Study Short Form Health Survey “Resultados médicos del formulario corto del estudio de la encuesta de salud”) o los instrumentos específicos para otras enfermedades, como el cuestionario AIMS (Arthritis Impact Measurement Scales “Escala de medición del impacto de la artritis”) puedan aplicarse a pacientes con gota.

Evaluar las características clinimétricas de los cuestionarios MOS-20 y AIMS y su correlación con el cuestionario HAQ-DI (Health Assessment Questionnaire ‘Cuestionario de evaluación de salud’) así como con variables clínicas en los pacientes con gota crónica tofácea (GCT).

Se incluyeron 49 pacientes con GCT. Se obtuvieron las variables demográficas y clínicas. Se aplicaron los 3 cuestionarios en la valoración basal. En 20 pacientes se realizó una segunda evaluación después de 8 semanas.
