Randomization Method
To be eligible for the study participants had to reside in one of the following San Antonio ZIP Codes with high levels of poverty: 78201, 78228, 78237, 78207, 78204, 78225, 78214, 78221, 78224, 78226, 78211, 78222, 78217. They also had to be between the ages of 18 and 60 and have a household income at or below 150% of Federal Poverty Level (FPL). Individuals receiving SSI or SSDI at the time of the application were ineligible for the study because participation in the program could affect their benefits.
Initial applications were screened for eligibility. If there were multiple applications from the same residential address, a single application was selected at random. Family Service then reached out via phone, text, and e-mail to individuals whose applications were eligible for the study and verified all eligibility criteria with each applicant. Applicants were asked to provide proof of age, address, and income. Applicants who were determined to be ineligible during the verification process or who declined to participate in the verification process were not invited to participate in the study and provided with community resource referrals.
Verified applicants were grouped according to their reported FPL: 0-50% of the FPL; 50-100% of the FPL; and 100-150% of the FPL. Within each FPL grouping, applicants were randomly assigned to treatment and control groups. This stratified randomization process ensured that each trial group would have a similar distribution of FPL levels. Once randomized into a trial group, applicants were notified of their selection into San Antonio G.O.A.L.S. and invited to enroll.
