Figures show that in the Netherlands rates of general health problems are higher among older migrants and are present at a younger age compared to the native older population. However, the prevalence in this group of certain aspects of mental health, such as loneliness, depression and cognitive impairment, remains relatively understudied. To be able to offer adequate diagnostics and health care for this group and conduct cross-cultural research, researchers and clinicians need reliable and valid health assessment scales. Özgül Uysal asks whether such scales are available for assessing these health issues in older Turkish, Moroccan and Surinamese migrants. She focuses on the cross–cultural validation of a loneliness and depression scale, and also evaluates the psychometric properties of a new dementia screening test in poorly-educated and illiterate older migrants in the Netherlands.
