  • Abstract

    The Monitoring STIs Survey Program (MSSP) monitored sexually transmitted infection (STI) prevalence among probability samples of adolescents and young adults aged 15 to 35 with landline phones in Baltimore, Maryland from 2006 to 2009. The MSSP collected survey data using telephone audio computer-assisted self-interviewing (TACASI) and biospecimens which were tested using nucleic acid amplification tests to monitor trichomonaiasis and other STIs. Respondents provided information about their sexual practices, sexual history, information about incarceration of themselves or their partners, and information about sexually transmitted diseases (STDs), STIs, and respective treatments. Demographic variables collected include gender, race, educational attainment, age, employment status, and marital status.

  • Methods

    The data are not weighted; however, this collection contains the weight variable ADJWGTC, which should be used in analysis. Two sets of sample weights were constructed to adjust for the unequal probabilities of selection based on the stratified sample design and survey nonresponse. Initial weights were developed reflecting the inverse probability of selection within each stratum with adjustments for the differing probabilities of selection within households, the number of landline telephones within the household, and survey nonresponse. A post-stratification adjustment was applied to align the sample distribution with the 2006-2009 United States Census estimates of the Baltimore City population by age, gender, and race/ethnicity. A second set of weights was constructed to compensate for additional differences in the provision of a biospecimen for STI testing among respondents who completed the survey interview. Analysis of these Trichomoniasis data should use the second weight which is named: "ADJWGTC". Please see the MSSP Weighting Information section in the ICPSR Codebook for more information about weighting.
  • 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: Checked for undocumented or out-of-range codes..

Sampled Universe
Baltimore, Maryland residents ages 15 to 35 in with a landline telephone. Smallest Geographic Unit: City
A stratified, list-assisted, probability sampling design was used to maximize sample efficiency in identifying the target population of English-speaking males and females between 15 and 35 years of age residing in Baltimore households with landline telephones. Over the course of the survey approximately 15 percent of Baltimore households did not have a landline telephone. In this design, all households with a landline telephone had a known probability of selection into the sample. The sample included four strata. The first three strata were sampled using commercially-available, regularly updated information on Baltimore households. These strata include (1) households believed to contain someone aged 15-35 years, (2) households with no one aged 15-35, and (3) households with residents of unknown age. The fourth stratum was constructed by selecting all known landline telephone numbers in Baltimore, and removing numbers on the original commercial list. Inclusion of this fourth stratum ensured that the probability sample included all households with landline telephones, and that each telephone number was in one and only one stratum. Errors in list-sample information (e.g., households that were erroneously thought to have a resident aged 15 to 35) were eliminated during survey screening. Please see the MSSP Brief Sampling Description section in the ICPSR Codebook for more information about sampling.
