Reference excerpt

The National Longitudinal Study of Adolescent to Adult Health, also known as Add Health, is a multiwave longitudinal study of adolescents in the United States. It was begun in 1994 in response to a Congressional mandate to study adolescent health, and was initially called the National Longitudinal Study of Adolescent Health. The first wave of the study, funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development, involved administering a questionnaire to a nationally representative sample of 7th- through 12th-graders during the 1994-95 school year. In the first wave of the study, the questionnaire was administered to about 20,000 adolescents, making it one of the largest longitudinal surveys of adolescents ever conducted. The participants were then re-interviewed in 1996 (wave II), 2001–02 (wave III), and 2008 (wave IV), with a fifth wave of data collection underway since 2016. The first three waves included, among other information, detailed and sensitive interviews, and the 11,500 participants in wave III also provided urine and saliva samples.

Objectives The purpose of Waves I and II was to examine factors associated with health behaviors among adolescents. The purpose of Wave III, which was conducted when almost all participants were aged 18 to 26, was to determine the relationship between behaviors and experiences during adolescence and behaviors during the adjustment to young adulthood. The purpose of Wave IV, conducted when almost all participants were aged 24 to 32, was to assess developmental and health trajectories over the lifespan.

Worked examples

Example 1 — a first encounter with National Longitudinal Study of Adolescent to Adult Health

Start with the simplest possible case. Write down what National Longitudinal Study of Adolescent to Adult Health 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 National Longitudinal Study of Adolescent to Adult Health 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 National Longitudinal Study of Adolescent to Adult Health 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 National Longitudinal Study of Adolescent to Adult Health

In research: National Longitudinal Study of Adolescent to Adult Health 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 National Longitudinal Study of Adolescent to Adult Health 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: National Longitudinal Study of Adolescent to Adult Health is common in secondary-school and first-year university syllabi. It links to neighbouring topics Health surveys, Projects established in 1994, Research projects, so understanding it makes those chapters shorter.
In everyday life: Look for National Longitudinal Study of Adolescent to Adult Health 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.
