BACKGROUND Although numerous health-related quality of life (HRQoL) instruments are available for patients with diabetes, the length of these measures may limit their feasibility to routine practice. Also, these measures do not distinguish items for generic and diabetes-specific HRQoL. This study was aimed to develop a diabetes-specific quality of life questionnaire module (DMQoL) to be in conj...

Αlcohol abuse/dependence seriously affects quality of life (QoL). The AlQoL-9 scale, derived from the generic instrument SF-36, is the only instrument in the international literature which is specific as a measure of QoL for alcohol-dependent patients. It can provide health carers with valuable information regarding the needs of alcoholic individuals and the effects of therapeutic interventions...
