Established in 2006, the Irish Longitudinal Study on Ageing (TILDA) (Kenny et al., 2010) is a unique study internationally that investigates the health and well-being of older people in the Republic of Ireland during two-yearly cycles. It aims to influence policy and change practice both within Ireland and globally (Wormald et al., 2019). This is achieved through the systematic collection, analysis, and dissemination of information ‘on all aspects of health, economic and social circumstances from people aged 50 and over’, resident within the Republic of Ireland (https://tilda.tcd.ie/). Objectives of the Evaluation
This evaluation, responds to the Health Research Board’s (HRB) Evaluation Strategy with the following specific objectives: • To collate and examine TILDA outputs, outcomes, and impact. • To assess the effectiveness of TILDA in delivering on the objectives specified in the grant agreement with the HRB. • To assess the efficiency of TILDA in relation to the cost of inputs. • To assess the performance and impact of TILDA in the context of comparable cohort studies internationally. • To use this information to examine the process and content of TILDA to determine its overall impact. • To develop learnings and recommendations for improvement of the TILDA programme of research and/or the current funding model.
