Discussion
-
The adaptation and translation of instruments for the assessment of mental and physical disorders in older people (e.g., CIDI65+, WHODAS-II, HoNOS-65+)
-
Establishing psychometric properties of and harmonising instruments for application within cross-sectional samples
-
Establishing prevalence rates (point, year and lifetime) of mental and physical disorders in the elderly in different countries of the EU
-
Identifying the level of mental disorder severity in older people
-
Identifying factors that promote and impair access to health services
-
Establishing levels of activity and impairment (based on ICF concepts) in older people with mental and physical disorders
-
Rating the quality of life in older people with mental and physical disorders
-
Quantifying the one-year incidence rate of mental disorders and the 12-month course and outcome of mental disorders in older people in different European countries
-
Identifying predictors affecting the course of mental and physical disorders of the elderly in the general population of six different EU countries
