Data from this study are based on 1261 surveys that were applied between May 22nd and June 21st, 2014, seven Centers for Social Rehabilitation in the Federal District (DF) and five of the state of Morelos in Mexico. A transversal survey was conducted through a representative sample of secluded population in seven prisons in the Federal District and five in the state of Morelos, randomly chosen on the basis of a reverse representation probability of their population of visitors. These two states were chosen because, even if they are adjacent, represent two types of centers: those located in urban areas and those located in rural areas. The preliminary design of the sample was performed taking into account the number of visitors to each center (based on records of visits between the months January 2013 and February 2014), from information provided via public information requests by the prison system authorities of the two states studied. This information was granted in February 2014. The survey was conducted in three phases: 1. First phase: the interviewers received a technical and operational training, with the main objective of familiarizing interviewers with the questionnaire, the context of the research and study purposes and limitations. During training they were instructed on how to approach the study subjects, emphasizing the voluntary, free and anonymous participation of respondents, and how to respond to questions and concerns of the participants. The team included 15 interviewers and 3 supervisors, plus a field coordinator. The team had extensive experience in prison studies, reflected in their education studies of undergraduate and masters specialized in Criminology: Social Work, Anthropology, Psychology and Sociology. During this first phase further efforts were made with the relevant authorities to achieve permanency in the centers studied, ensuring safety conditions for both interviewers and participants of the study. 2. Second phase: a pilot test was conducted in two centers in the Federal District to test the questionnaire, the clarity of language, and the extension. This test allowed to make changes to the questionnaire, and to calculate the percentage of "no answers". One of the key objectives of the pilot will be to test the possibility of an exit survey, which would have information on the immediate experience of the subjects. For the pilot surveys 30 surveys were conducted at two centers in the Federal District. The surveys used in the pilot were not used in the final results. 3. Third phase: field survey. Surveys were applied face to face to men and women, once they had completed their visits to the center; the survey was voluntary under the promise of anonymity. The surveys were conducted on Saturdays and Sundays. The collection in the Federal District employed 16 interviewers and 4 supervisors, and in Morelos, 14 interviewers and 4 supervisors. For the selection of the subjects a systematic sampling, with a random start, at each center, each day. (Ex. 2, 7, 9, 18, 22, 23, etc ... until completing the sample). Each day began with an initial random number. The field supervisor used a table of random numbers daily at each center to ensure random selection of subjects. Given the number of surveys conducted in different centers, the study does not allow comparison between centers, but it does allow comparison between states. The information processing was carried out simultaneously with the field survey. The sample was designed by Dr. Carlos Vilalta, Research Professor, Centro de Investigación y Docencia Económicas (CIDE), based on information about visitors provided by the authorities of each state. In both states, coordination was carried out by Dr. Catalina Pérez Correa and Dra. Maria Cristina Monta√±o.
