Q -- REWEIGHTING EXISTING NATIONAL AIDS BEHAVIORAL SURVEY (NABS) DATA SETS SOL 1999Q00101 DUE 040199 POC Andrew B. Kegler, Purchasing Agent, (770) 488-2639 The Centers for Disease Control and Prevention (CDC) intends to negotiate with and award a contract to Dr. Joseph A. Catania, Aids Research Institute, University of California, San Francisco. The award will be made on a sole source basis for professional services for the vendor to provide data files containing appropriate sampling weights, reports on how weighting was conducted, survey instruments, general methods reports, variable dictionary and maps including notes on construction of aggregate variables and complex skip cautions, notes on idiosyncrasies of the data set. The aim of this procurement is to obtain separate data sets with new weighting factors for the following cities: Chicago (n = 1266), Detroit (n = 583), Houston (n = 925), Los Angeles (n = 1477), Miami (n = 1068), New York (n = 807), Philadelphia-Camden (n = 587). These cities have sample sizes, which would produce reasonable point estimates of even low prevalence behaviors. These 7 data sets would provide the respective cities with baseline estimates of risk behavior and prevention practices with which to compare to more recent estimates derived by local resources which will give estimates of community change. Additionally, this requirement is for technical statistical services that would make it possible to produce estimates of HIV risk behavior and prevention practices for 7 individual large metropolitan areas, based on national telephone surveys conducted in 1990 and 1996. These estimates can serve as baselines for comparing more recent local data from these areas, and assessing change and impact of prevention activities. Finally, this requirement is for statistical work to make it possible to compare the 1996 survey with the 1990 survey for the entire domain of high risk HIV metropolitan areas, in order to assess change. These activities would result in new statistical data sets, from which it will be possible to make these estimates. The National AIDS Behavioral Surveys data are unique in measuring HIV risk behaviors and preventive activities and having sufficient numbers of cases to make estimates for metropolitan areas. Simplified Acquisition Procedures will be utilized. This requirement is 100% small business set-aside with a SIC code 8733. For purposes of this acquisition, a business concern is considered small if it (including affiliates) has no more that $5 million average annual receipts for the three fiscal years. Other that full and open competition is authorized pursuant to 41 U.S.C. 253(c)(1),FAR 6.302-1. The minimum qualifications include, but are not limited to the following: Extensive knowledge of the technical aspects of survey sampling, and experience in developing survey research data files and documentation. In addition, it will require access to raw data files from the NABS and National Sexual Health Survey (NSHS) surveys together with data on sampling methods, selection probabilities and other technical aspects of data collection on these surveys, in order to develop appropriate statistical weighting factors. Qualified vendors have 15 days from date of this synopsis to submit a capability statement delineating their ability to provide these services. Such qualifications will be used solely for the purpose of determinating whether or not to conduct this procurement on a full and open competition basis. Documents may be mailed to the above address or by facsimile at 770 488-2671. No solicitation document exists. See Numbered Notes 1 and 22. Posted 03/16/99 (I-SN308961). (0075)
