Protocol - Perceived Availability of Illegal Drugs and Alcohol
Description
The Monitoring the Future (MTF) project studies changes in the beliefs, attitudes, and behavior of young people in the United States. The MTF is a repeated series of surveys in which the same segments of the population (8th-, 10th-, and 12th-graders; college students; and young adults) are presented with the same set of questions over a period of years to see how answers change over time. Respondents complete self-administered questionnaires.
Specific Instructions
Results are typically analyzed in terms of the fraction of respondents reporting that it is either "Very easy" or "Fairly easy" to get the drug/substance. Analysis of the variable constructed in this fashion can be directly compared to findings in Monitoring the Future (MTF) and National Survey on Drug Use and Health (NSDUH) samples.
