The Irish Longitudinal Study on Ageing

The Irish Longitudinal Study on Ageing is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand The Irish Longitudinal Study on Ageing rather than just read about it. In short: The Irish Longitudinal Study on Ageing (TILDA) is a nationally representative longitudinal study of the population of Ireland aged 50 and above. TILDA aims to understand the health, social and financial circumstances of the older Irish population and how these factors interact.

Key takeaways

The Irish Longitudinal Study on Ageing belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect The Irish Longitudinal Study on Ageing to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of The Irish Longitudinal Study on Ageing from memory before moving on to harder problems.

Reference excerpt

The Irish Longitudinal Study on Ageing (TILDA) is a nationally representative longitudinal study of the population of Ireland aged 50 and above. TILDA aims to understand the health, social and financial circumstances of the older Irish population and how these factors interact. The study is led by Trinity College Dublin (TCD) in collaboration with a majority of the other principal academic institutions in Ireland. A wide range of experts from many disciplines have been involved from the outset in the development and execution of this study.

Study design The respondents for the TILDA study were derived from a nationally representative study of the population of Ireland aged 50 years and over. 8500 people were interviewed for Wave 1 of the study. This involved a Computer-Assisted Personal Interview (CAPI), a Health Assessment and a Self Completion Questionnaire. The Health Assessment involved cognitive, gait and cardiovascular tests, as well as procedure to measure macular degeneration. This Health Assessment was carried out in TILDA health centres in Dublin and Cork. A health assessment will be performed in Waves 1, 3 and 5. The CAPI and the SCQ will be performed in all waves.

Data collection The first wave of data collection was conducted between October 2009 and July 2011. The second wave of data collection began in January 2012, and was scheduled to be completed in December 2012.

Related studies TILDA is designed to maximise comparability with other well-established international longitudinal studies, in particular Health and Retirement Study (HRS) in the US, the Survey of Health, Ageing and Retirement in Europe (SHARE), and the English Longitudinal Study of Ageing (ELSA), and thereby to facilitate cross-country comparisons.

Worked examples

Example 1 — a first encounter with The Irish Longitudinal Study on Ageing

Start with the simplest possible case. Write down what The Irish Longitudinal Study on Ageing claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to The Irish Longitudinal Study on Ageing before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about The Irish Longitudinal Study on Ageing ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of The Irish Longitudinal Study on Ageing

In research: The Irish Longitudinal Study on Ageing appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses The Irish Longitudinal Study on Ageing in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: The Irish Longitudinal Study on Ageing is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cohort studies, Health in the Republic of Ireland, Old age by country, so understanding it makes those chapters shorter.
In everyday life: Look for The Irish Longitudinal Study on Ageing outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
