Page 5 - When verification forms did not have a telephone number but did have an address, verification by mail was attempted. Discrepancies were identified, and the appropriate field supervisor was notified by electronic mail for resolution; all discrepancies were satisfactorily resolved. Verification interviews, follow-up letters, and records of any discrepancies and their resolution were filed with the respondents

Page 4 - NHSDA, the design-based variance was estimated using a Taylor series linearization. For a given variance estimate, the associated design effect is the ratio of the design-based variance estimate over the variance that would have been obtained from a simple random sample of the same size. Because the combined design features of stratification, clustering, and unequal weighting are expected to increase the variance estimates, the design effect should virtually always be greater than one. However, for...
Page 5 - For computational purposes, this is equivalent to > 0.175 when pi 0.5 > 0.175 when p > 0.5 where SE(p) equals the standard error estimate of p. The log transformation of p is used to provide a more balanced treatment of measuring the quality of small, large, and intermediate p values. The switch to (1-p) for p greater than 0.5 provides a symmetric suppression rule across the range of possible p values.

Page 4 - PSUs were selected with probability proportional to a composite size measure. The composite size measure was defined as the sum of racial/ethnic group dwelling counts weighted by the specified racial/ethnic sampling rates. This selection scheme allowed for targeting particular racial/ethnic subpopulation sample sizes. Chromy's (1979) probability minimum replacement sequential sampling scheme was used to select these 72 PSUs with probabilities proportional to their composite size measures.
Page 1 - This report provides estimates of the percentages and numbers of the US household population who have used illicit drugs, alcohol, and tobacco in their lifetime, in the past year, and in the past month. It also contains information about needle use and the frequency of use of marijuana, cocaine, crack cocaine, inhalants, hallucinogens, psychotherapeutics, PCP, heroin, cigarettes, smokeless tobacco, and alcohol. Information is presented in tabular form with little or no explanatory text. This report...

Page 1 - Abuse is the twelfth in a series of studies designed to measure the prevalence and correlates of drug use in the United States and to monitor drug use trends over time. The National Commission on Marihuana and Drug Abuse sponsored the first two studies conducted in 1971 and 1972. The National Institute on Drug Abuse (NIDA) sponsored the NHSDA from 1974 to 1991. In October 1992, responsibility for conducting the NHSDA and preparing reports was moved to the Office of Applied Studies (OAS) within the...
Page 5 - This section describes methods used to compare prevalence estimates. Customarily, the observed difference between estimates is evaluated in terms of its statistical significance. "Statistical significance" refers to the probability that a difference as large as that observed would occur due to random error in the estimates if there were no difference in the prevalence rates for the population groups being compared.
