Monitoring the Future

Monitoring the Future 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 Monitoring the Future rather than just read about it. In short: The Monitoring the Future (MTF) study, also known as the National High School Senior Survey, is a long-term epidemiological study that surveys trends in legal and illicit drug use among American adolescents and adults as well as personal levels of perceived risk and disapproval for each drug.

Key takeaways

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

Reference excerpt

The Monitoring the Future (MTF) study, also known as the National High School Senior Survey, is a long-term epidemiological study that surveys trends in legal and illicit drug use among American adolescents and adults as well as personal levels of perceived risk and disapproval for each drug. The survey is conducted by researchers at the University of Michigan's Institute for Social Research, funded by research grants from the National Institute on Drug Abuse, one of the National Institutes of Health.

Survey design The survey began in 1975 and only focused on that year's senior class. Questionnaires are sent out yearly by mail. Beginning in 1976, a proportion of survey participants were also chosen for biennial reevaluations. In 1991, the survey was expanded to include 8th and 10th grade students. The questionnaire is anonymous for 8th- and 10th-grade students while the questionnaire for 12th-grade students is confidential—name and address information is collected for longitudinal follow-up surveys. Nationally representative samples of 8th-, 10th-, and 12th-grade students (The 2010 MTF survey encompassed about 46,500 students from almost 400 schools nationwide) receive a questionnaire investigating substance use patterns, attitudes and beliefs about drugs, perceived availability of drugs, and norms among peer and role model groups. Currently, approximately 50,000 8th, 10th and 12th-grade students complete the survey annually. The survey also evaluates a variety of topics beyond drug use. Questionnaire questions also explore subjects' occupational and educational plans and experiences, attitudes about gender roles, attitudes and experiences with people of a different race/ethnicity, trust in government and other institutions, concerns about the environment, media consumption, victimization and delinquency, among other things. Follow-up studies into adulthood also cover marriage and family formation, college attendance, military service, civilian employment, unemployment, and other topics.

Regular marijuana and cigarette use by 12th graders Chart below is from a NIDA article. Text at the top was added later. Chart is for regular marijuana and cigarette use by 12th graders in the USA in the past 30 days. For cigarettes actual daily use is measured. For marijuana it is for use on 20 or more occasions in the past 30 days.

Worked examples

Example 1 — a first encounter with Monitoring the Future

Start with the simplest possible case. Write down what Monitoring the Future 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 Monitoring the Future 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 Monitoring the Future 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 Monitoring the Future

In research: Monitoring the Future 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 Monitoring the Future 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: Monitoring the Future is common in secondary-school and first-year university syllabi. It links to neighbouring topics Drugs in the United States, Epidemiological study projects, so understanding it makes those chapters shorter.
In everyday life: Look for Monitoring the Future 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.

Frequently asked questions

What is Monitoring the Future in simple terms?

Why does Monitoring the Future matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Monitoring the Future?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
