Using a mixed-sampling plan, werandomly selected 58 English- and Spanish-speaking mothers from the full study sample; 51 motherswere located and agreed to participate in either the first or second qualitative interview. Because thequalitative study started a year after the larger study, and we wanted to interview mothers when theirchildren were young, we limited the sample pool to mothers whose babies were born in 2005. We alsoexcluded Haitian Creole–speaking mothers from the qualitative sample because they are a smallproportion of the larger sample, and we did not have resources to hire a Creole-speaking interviewer.Thus, we divided the sample pool by initial risk level and then sampled Glades and non-Glades mothersin proportion to their representation in the larger study.Qualitative interviewers met with families twice a year to conduct in-depth, semistructured interviews thatlast about 90 minutes. 82 All interviews were tape-recorded with the permission of mothers, transcribed,and validated to confirm the accuracy of the transcription. In the case of interviews conducted in Spanish,translation was carried out concomitantly with transcription. Interviewers also wrote detailed summarynotes of the information collected during the interview and their observations of the home andneighborhood environment, parent-child interactions, and child behavior.82 The qualitative interviews are conducted by four trained graduate students from Florida Atlantic University and FloridaInternational University. All have had previous experience with qualitative methodology, and two are fluent in Spanish.Chapin Hall at the University of Chicago 163
