   Sammanfattning : Background and Objectives: With an ageing population, the number of older persons with substance use problems, particularly problematic alcohol use, is increasing. Despite grow­ing recognition of the negative consequences of problematic alcohol use on older persons, there is a dearth of knowledge about the alcohol use profiles and the dimensionality of alcohol problems in older people.
