The national and local Chicago news media have publicized law enforcement actions and adverse health outcomes, including fatalities, related to the abuse of these substances. Media accounts and a limited body of research have identified use of these substances as prevalent in the gay male community. This prevalence coincides with recent increases in HIV seropositive incidence. There is a clear need for a more comprehensive understanding of the prevalence of club drug use in the general population, and particularly in the subgroup of sexually active gay men. Noting these research gaps and their considerable adverse public health implications, this supplemental study was designed to apply an expanded protocol developed from an earlier study conducted (Feasibility and Use of Biological Measurement in Drug Surveys; R01DA12425, SRL Study #860) to a sample of gay men in the city of Chicago (Michael Fendrich, Principal Investigator). This study evaluated whether findings regarding the feasibility and use of drug testing in drug surveys derived from general population samples are generalizable to a probability sample of 216 gay men in the city of Chicago. For this project, a supplemental module was added to the main study survey that asked detailed questions about involvement in the gay community, risky sexual activity and HIV seropositivity. The scope of biological measurement was also expanded to incorporate testing for Rohypnol and Ketamine in hair (MDMA was already being tested as part of the general sample hair screen). The dataset contains 676 variables. 2002-09 2003-01 2002-09 2003-01 Chicago Illinois United States ZIP code individual Eligible men between the ages of 18 and 55 who self-identified as being homosexual, bisexual, or as having ever had sex with another man, living in households within two Chicago ZIP codes. clinical data survey data The geographic area covered in this research included households within two Chicago ZIP codes. The sample was selected in three stages within the two ZIP codes. First, city blocks were randomly selected. Second, all of the households on the selected blocks were listed in the sample. At the third stage of selection, each of the selected households was screened to determine if any residents were eligible. If more than one resident in a household was eligible, a respondent was randomly selected using the 'next-birthday' method. The final sample size was 7,644 households within 44 census blocks. Please consult the study documentation for further information regarding the sample design. audio computer-assisted self interview (ACASI) , computer-assisted personal interview (CAPI) , computer-assisted self interview (CASI) , face-to-face interview , on-site questionnaire One weight, adt_wgt, has been calculated for use in analysis. The weight variable adt_wgt is the adjustment for differential probability of selection of eligible adults in the household. Please consult the study documentation for further information regarding sample weighting.

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:

Created variable labels and/or value labels.Standardized missing values.Checked for undocumented or out-of-range codes. Entire sample response rate: 34.86 percent. This response rate is calculated in the following manner: The numerator includes completed interviews, and the denominator includes interviews, refusals, non-contact of eligible respondents, and a proportion of households whose eligibility status is unknown. Please consult the study documentation for further information regarding response rates.
