Post Coital DNA Recovery in Minority Proxy Couples, United States, 2014-2018 (ICPSR 37250)
Introduction and Background. Minorities are less likely to report rapes. The Post Coital DNA Recovery (PCDR) study (2009-14) subjects were white (93%) where expanded collection times were not generalizable to minority populations. Evidence reports health and medical differences between races necessitating duplication of previous research in minority populations.
Aims. (1) What is the time period in which it is possible to collect post-coital DNA in minority women using Y-STR laboratory methods? and (2) when compared to the former study sample of minority and non-minority, what are the physiological conditions, factors, or activities in minority couples that influence post-coital DNA recovery?
Design. The design includes mixed methods duplication perfected in the first study, embracing descriptive and inferential techniques. Qualitative research used semi-structured interviews. Aim 1 analysis used PCDR-M data only. Aim 2 combined data from both PCDR and PCDR-M studies. Combined, DNA recovery, a binary outcome accounting for repeated methods in population regression analysis, used Generalized Estimating Equation (GEE) methods.
Fidelity. The strict criteria for adherence included considerable outreach and support of study personnel. PCDR and PCDR-M data combined and compared the two samples, which had specific homogeneity, including same inclusion and elimination criteria in both studies; fidelity to the validated protocol; laboratory method and interpretation for inclusion; duplicate statistical analysis; and interpretation of data. Any variation in key variables met elimination criteria.
Assumptions and Limitations. Assumptions included (1) motivation is altruistic; (2) motivation is incentives and coercion for some; (3) negotiating coitus is difficult and stressful; and (4) similar fidelity and dropout rates. The limitations included (1) a lack of representation for the diverse experiences of rape victims; (2) sample size; (3) self-selection bias; (4) protocol adherence; and (4) advances in laboratory science and DNA kits.
Demographics. Demographic variables included gender, race, and age. Major categories in the dataset included participants' reproductive history, data on female participants' reproductive organs, and childhood abuse.

Washington, DC, Metropolitan Area Drug Study (DC*MADS), 1992: Drug Use Among DC Women Delivering Live Births in DC Hospitals (ICPSR 2347)
The Washington, DC, Metropolitan Area Drug Study (DC*MADS) was conducted in 1991, and included special analyses of homeless and transient delivering live births in the DC hospitals. DC*MADS was undertaken to assess the full extent of the drug problem in one metropolitan area. The study was comprised of 16 separate studies that focused on different sub-groups, many of which are typically not included or are underrepresented in household surveys.
The DC*MADS: Drug Use Among Women Delivering Livebirths in DC Hospitals was designed to examine the nature and extent of drug use among women delivering live births in eight Washington, DC, hospitals participating in the study. Data from the questionnaires include prenatal care, health problems during pregnancy, pregnancy drug use history, needle use, polysubstance use, patterns of use, respondent's general experiences with drug use, including perceptions of the risks and consequences of use, occurrence of psychological and emotional problems, income and insurance coverage, treatment experiences, and maternal and infant outcomes. Medical records were abstracted from the women and their infants to document medical problems. Abstracted data on the mothers included demographics, discharge diagnoses, disposition at discharge, and results of urine screens. Abstracted data on infants included delivery information, status at discharge, discharge diagnoses/procedures, and first urine toxicology screen results.
