Abstract
in English, Spanish

An instrumental study of 392 households with sick or disabled members was conducted to analyze the psychometric properties of the Family Disease Management Scale. Three different models were analyzed using the Confirmatory Factor Analysis (CFA). One was a single-dimensional factor (family disease management) with 30 items; and two hierarchical models with three factors, which represent the dimensions, family support, family normalization and family participation, that placed the workload into another of higher order called family disease management, the first with 30 items and the second with 29. The CFA results showed that the latter 29-item model provided a better fit. The internal consistency analysis using the Cronbach alpha test showed a value of .93 for the complete scale and above .80 in the three subscales. This instrument may be useful to assess how families manage the illness or disability of its members, especially in clinical practice given the importance of the family as the primary caregiver. As well as in performing epidemiological studies, and in the field of management, planning and assistance.

Se realizó un estudio instrumental en 392 familias con miembros enfermos o discapacitados para estudiar las propiedades psicométricas de la Escala Manejo Familiar de la Enfermedad. Se analizaron tres modelos mediante Análisis Factorial Confirmatorio (AFC): uno con un factor (Manejo familiar de la enfermedad) con 30 ítems y otros dos jerárquicos, con tres factores, para las dimensiones apoyo familiar, normalización familiar y participación familiar, cuyos pesos se depositan en otro factor de orden mayor denominado Manejo familiar de la enfermedad, el primero con 30 ítems y el segundo con 29. Los resultados del AFC mostraron que el último modelo de 29 ítems obtuvo mejor ajuste. El análisis de la consistencia interna mostró valores de 0,93 para la escala completa y mayores de 0,80 en las tres subescalas. El instrumento podría usarse para valorar el manejo de la enfermedad o discapacidad de sus miembros por parte de las familias, especialmente en la práctica clínica, dada la importancia de la familia como cuidadora principal. También podría ser útil en estudios epidemiológicos o en la gestión y planificación sanitaria.
