  • Abstract

    These surveys of 8th- and 10th-grade students are part of a series that explores changes in important values, behaviors, and lifestyle orientations of contemporary American youth. Students in each grade are randomly assigned to complete one of four questionnaires, each with a different subset of topical questions but containing a set of "core" questions on demographics and drug use. There are more than 450 variables across the questionnaires. Drugs covered by this survey include amphetamines (stimulants), barbiturates (tranquilizers), other prescription drugs, over-the-counter medications, tobacco, smokeless tobacco, vaping, alcohol, inhalants, steroids, marijuana, hashish, LSD, hallucinogens, cocaine, crack, ecstasy, methamphetamine, and injectable drugs such as heroin.
  • Methods

    A total of 29,980 students completed a survey in 2018. There were 14,836 8th graders and 15,144 10th graders. The number of students completing each form were: Form 1: 9,995; Form 2: 10,018; Form 3: 5,000; Form 4: 4,967; The split is approximately equal between forms completed by 8th graders and 10th graders.
  • Methods

    The downloadable data file contains a total of 583 variables. The file provided by the Principal Investigators contained 553 variables (542 survey questions and 9 administrative variables). ICPSR created the other 30 variables of the final file to aid in analysis and utility. Not all of the 542 survey questions were asked on each form. There are 135 variables (25 percent) that are common amongst all 4 forms. Each variable label contains a notation of which forms asked that particular question. On average each form asked approximately 300 questions (55 percent). All of the survey questions are categorical in nature. The majority of questions fall into one of seven types of response options. Yes / No; Marked / Not Marked; Agree / Disagree scale (5 point); Disapproval scale (3 point); Risk scale (4 point); Frequency of days (6 point); Frequency of use (7 point);
  • Methods

    ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection: Standardized missing values.; Created online analysis version with question text.; Performed recodes and/or calculated derived variables.; Checked for undocumented or out-of-range codes..
  • Methods

    Response Rates: The student response rates for the 2018 8th- and 10th-grade surveys were 89 percent and 86 percent, respectively.

Sampled Universe
Enrolled 8th- and 10th-grade students in the contiguous United States. Smallest Geographic Unit: Census Region
A multistage area probability sample design was used involving three selection stages: (1) geographic areas or primary sampling units (PSUs), (2) schools (or linked groups of schools) within PSUs, and (3) students within sampled schools. Of the 72 PSUs, 8 were selected with certainty, 10 were selected with a probability of .50, and the remainder were selected using a probability based on their 2010 Census household count. Generally speaking, in schools with more than 350 students in the grade, a sample of students or classes was drawn. In schools with fewer than 350 students in a grade, all students were asked to participate unless logistical challenges required a sample be taken. For the 8th-grade survey, schools with fewer than 20 8th graders were generally excluded from the sample. For the 10th-grade survey, schools with fewer than 25 10th graders were excluded, with very few exceptions. Each school was asked to participate for two years so that each year one-half of the sample would be replaced. Schools refusing participation were replaced with similar schools in terms of geographic location, size, and type of school (e.g., public, private/Catholic, private/non-Catholic). The participation rate among schools has been between 66 and 80 percent since the inception of the study.
