Protocol Name from Source:

Monitoring the Future (MTF) 2015

Availability:

Publicly available

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.

Mode of Administration

Self-administered

Life Stage:

Adolescent, Adult

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.

Research Domain Information

Release Date:

November 21, 2016

Definition

Instrument used to gather respondents’ perceptions of the availability of substances including illegal drugs and alcohol.

Purpose

The purpose of this measure is to collect information from respondents on how readily available different types of substances are to them. The substances included in the protocol are marijuana, LSD, PCP (angel dust), MDMA (ecstasy), crystal meth ("ice"), steroids, cigarettes, and alcohol.

Selection Rationale

The Monitoring the Future (MTF) protocol was chosen because it has been used in a comprehensive research project with large samples that are nationally representative. The measures for this questionnaire have been validated and used widely in the literature.

Process and Review

The [link[phenx.org/Default.aspx?tabid=1041|Expert Review Panel #3]] (ERP 3) reviewed the measures in Alcohol, Tobacco and Other Substances, and Substance Abuse and Addiction domains.

Guidance from ERP 3 includes:

• Changed name of Measure

• Updated protocol

• New Data Dictionary

Back-compatible: Partially back-compatible (updated/similar protocol which would require some changes to the data dictionary), variable mapping between current and previous protocols can be found here <link>
