Abstract

Background: Depression and anxiety are frequent comorbid conditions in cardiovascular diseases (CVDs); they are related to poor prognosis and higher mortality risk. Health providers need a clinical tool to identify these psychiatric conditions. The 14-item hospital anxiety and depression scale (HADS) is a screening tool used in patients with different medical conditions.

Objective: The aim of this study was to evaluate the psychometric properties of the HADS Mexican Spanish version in a broad sample of Mexican patients with CVDs.

Materials and methods: A total of 953 individuals between 18 and 75 years old with ischemic or hypertensive cardiomyopathy were screened with the HADS Mexican Spanish version. Construct validity, internal consistency, and congruence coefficients of the scale were obtained.

Results: The results showed two clear factors which correspond to the original two designated domains of the HADS, anxiety, and depression, with adequate reliability values (alpha > 0.80) and high congruence coefficients (> 0.90) when compared to the sample of other validation studies of the HADS.

Conclusions: The present study adds evidence of the validity and reliability of the HADS to assess the presence of both depression and anxiety in Mexican patients with CVD. Its central contribution is that it demonstrates its capacity to differentiate the presence and severity of depression and anxiety in this population.

Antecedentes: La depresión y la ansiedad son afecciones comórbidas frecuentes en las enfermedades cardiovasculares; se relacionan con mal pronóstico y mayor riesgo de mortalidad. Los proveedores de salud requieren de una herramienta clínica para identificar estas condiciones psiquiátricas. La Escala de Ansiedad y Depresión Hospitalaria de 14 ítems (HADS) es una herramienta de detección utilizada en pacientes con diferentes afecciones médicas.

Objetivo: Evaluar las ­propiedades psicométricas de la versión mexicana-española de la HADS en una amplia muestra de pacientes mexicanos con enfermedades cardiovasculares (ECV).

Método: Un total de 953 individuos entre 18 y 75 años de edad con cardiomiopatía isquémica o hipertensiva se examinaron con la versión Mexicana en español de la HADS. Se obtuvieron la validez de constructo, la consistencia interna y los coeficientes de congruencia de la escala.

Resultados: Los resultados mostraron dos factores que corresponden a los dos dominios designados originales de la HADS, ansiedad y depresión, con valores de confiabilidad adecuados (alfa > 0.80) y altos coeficientes de congruencia (> 0.90) en comparación con la muestra de otros estudios de validación de la HADS.

Conclusiones: El presente estudio sustenta la validez y confiabilidad de la HADS para evaluar la presencia de depresión y ansiedad en pacientes Mexicanos con ECV. Su contribución central es su capacidad para diferenciar la presencia y la gravedad de la depresión y la ansiedad en esta población.
