The Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing (IDS-TILDA) Wave 5, 2023

The Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing (IDS-TILDA) is a longitudinal study researching ageing in Ireland among people with an intellectual disability aged 40 and over. This study is the first of its kind in Europe, and the only study able to directly compare the ageing of people with an intellectual disability with the general ageing population. The underpinning values of IDS-TILDA are inclusion, choice, empowerment, person centred, the promotion of people with intellectual disability, the promotion of best practice and to contribute to the lives of people with intellectual disability. The objectives of IDS-TILDA are: To understand the health characteristics of people ageing with an intellectual disability; To examine the service needs and health service utilization of people ageing with an intellectual disability; To identify disparities in the health status of adults with an intellectual disability as compared to TILDA findings for the general population; and To support evidence-informed policies, practices and evaluation. IDS-TILDA completed its fifth Wave of data collection in 2023. A total of 762 participants completed the Computer Assisted Personal Interview (CAPI) at Wave 5, consisting of 621 participants who had previously taken part in Wave 4 and 141 newly recruited participants.
