The 1992 Texas School Survey results for secondary students are based on data collected from a sample of 73,073 students in grades 7 through 12. Students were randomly selected from school districts throughout the state using a multi-stage probability design. The procedure ensured that students living in metropolitan and rural areas of Texas are proportionately represented in the final estimates. Sampled districts are geographically distributed throughout Texas. The secondary student instrument asks about use of 11 drugs including tobacco, alcohol, inhalants, marijuana, cocaine, crack, hallucinogens, uppers, downers, steroids, and Ecstasy. Other questions pertain to behavioral and demographic correlates of substance abuse, sources of information about and help for substance abuse problems, peer values, and the perceived safety of the students' environment. Texas 8th- and 10th-graders are more likely than national 8th- and 10th-graders to have used cigarettes, alcohol, marijuana, and cocaine, but less likely to have used hallucinogens. In contrast, Texas seniors are less likely than national seniors to report current use of cigarettes and marijuana, about equally likely to have drunk alcohol in the past month, and slightly more likely to use cocaine. The survey instrument is included. (KM)
