La sociedad española de Reumatología (SER) (rivera et al., 2006) recomienda la escala de ansiedad y Depresión Hospitalaria (Hospital anxiety and Depression Scale - HADS, Zigmond y Snaith, 1983) para la evaluación clínica de ansiedad y depresión en Fibromialgia (FM). sin embargo, no constan índices de sensibilidad/especificidad ni puntos de corte en FM. Con el objetivo de comprobar aplicabilidad, propiedades psicométricas y sensibilidad/especificidad del HAD en FM, se evaluó a 131 pacientes ambulatorios del Hospital de san Vicente (alicante, España), utilizando como criterios externos BDI y STAI-E. se analizaron ítems, consistencia interna y estructura factorial mediante análisis confirmatorio y puntos de corte con curvas ROC. Se replicó la estructura de dos factores. La fiabilidad es adecuada (HADA=.80, HADD=.85). Se muestran diferentes puntos de corte con sensibilidad/especificidad superior al 70% para cada subescala. El Had presenta propiedades psicométricas óptimas en población FM, mostrándose útil como instrumento de "screening" de sintomatología ansioso-depresiva en esta población. Spanish Society of Rheumatology (SER) (Rivera et al., 2006) suggests the Hospital Anxiety and Depression Scale (HADS, Zigmond y Snaith, 1983) for clinical assessment of anxiety and depression in fibromyalgia (FM). However, there is no HAD-FM cut-off yet. Aiming to assess applicability, psychometric properties and sensitivity/specificity of HADS in FM, 131 outpatients were assessed at San Vicente Hospital (Fibromyalgia service, Alicante, Spain), using like external criteria BDI and STAI-E. Item analysis was performed, calculating the internal consistency and factor structure study by confirmatory factor analysis (CFA). The cut-off points were found by ROC curves. Two-factor structure was replicated. Reliability is adequate (HADA=.80, HADD=.85). Several cut-off points are showed with sensitivity and specificity levels >70% for both subscales. HADS has optimal psychometric properties in FM and its useful as a screening tool to assess anxious-depressive symptoms in FM patients. |
