The legislative mandate for this report requires inclusion of information about relevant research on the Supplemental Security Income (SSI) program by the Social Security Administration (SSA) and others. Section 1 of this appendix describes SSA’s major ongoing projects. Section
2 presents a bibliography of studies regarding SSI payment levels, recipients, and reform proposals published in the past 10 years by both public and private entities.
We used the model to simulate the potential effects of several approaches to expand the SSI program to fight poverty among the elderly. Approaches focusing on incremental changes in the Federal benefit rate, the general income exclusion, and the resources test appear roughly equally effective in reducing the poverty gap among the elderly on a cost-equivalent basis, while two approaches focusing on relaxing the earned income exclusion are less effective (Davies, Rupp, and Strand 2004). We expanded the model to address SSI participation and financial eligibility among the working-age disabled and to assess SSI benefit restructuring options for the entire SSI population. The working-age model allows for the identification of working-age persons by their SSI financial eligibility status, Social Security Disability Insurance (SSDI) insured status, and participation in both programs. We used the expanded model to assess SSI’s role in complementing SSDI and enhancing the safety net for the working-age population (Rupp, Davies, and Strand 2008). We simulated the effects of several approaches to changing in-kind support and maintenance rules and options for altering the calculation of the Federal benefit rate for certain living arrangement categories (Balkus et al. 2009). We also studied eligibility for Medicare buy-in programs with the financial eligibility model (see Rupp and Sears 2000; Sears 2001/2002). In unpublished internal research, we used the model to estimate the size of the population potentially eligible for the Medicare Part D low income subsidy.
A number of studies by SSA researchers provide a better understanding of the SSI program, the elderly and disabled target populations, program interactions, and the role of the SSI program in the United States social safety net. Nicholas (2013) as well as Koenig and Rupp (2003/2004) estimate the prevalence, characteristics, and poverty status of SSI recipients living with others on SSI (who are not an eligible spouse) in the context of their individual, family and household units. In 2003 and again in 2005, SSA provided funding for interviewing supplemental samples of SSI and SSDI beneficiaries to increase the SIPP sample size available for analyses of these target groups. DeCesaro and Hemmeter (2008) examines the characteristics of SSDI and SSI program participants using the 2003 supplemental sample combined with the 2001 SIPP, both matched to administrative records. Bailey and Hemmeter (2014) updated this research note using the 2008 SIPP matched to 2010 administrative records to examine the characteristics of SSDI and SSI program participants. Rupp and Davies (2004) tracks survey respondents from the 1984 SIPP for 14 years using administrative records on SSI and SSDI participation and death events to assess the relationship between self-reported health status, disabilities, mortality, and participation in the SSI and SSDI programs. Weathers et al. (2007) uses a unique longitudinal dataset based on administrative data from the National Technical Institute for the Deaf (NTID) linked to our administrative records to conduct a case study of SSI children who applied for postsecondary education at NTID. Hemmeter, Donovan, Cobb and Asbury (2015) compare the outcomes of participants in the Marriott Foundation for People with Disabilities Bridges from School to Work program with non-participating SSI recipients. Another study uses our administrative records from August 2005 through August 2007 to analyze SSI recipients who lived in counties and parishes affected by Hurricanes Katrina and Rita (Davies and Hemmeter 2010). Hemmeter (2009) examines the occupational distribution of SSI disability recipients aged 18-61 who work. Hemmeter and Gilby (2009) analyzes age-18 redetermination outcomes for SSI youth, including appeals of initial cessations and subsequent reapplications for benefits after a period of ineligibility, while Hemmeter (2012) looks at changes in diagnostic codes following the age-18 redetermination. Another research study examines the subsequent participation in the SSDI and SSI programs by individuals whose eligibility for those programs ceased through a continuing disability review because of medical improvements (Hemmeter and Stegman 2013). Rupp (2012) analyzes factors affecting initial disability allowance rates for the SSDI and SSI programs and finds that demographic and diagnostic characteristics of applicants and the local unemployment rate substantially affect the initial allowance rate.
Using data from the Current Population Survey matched to our administrative records, Nicholas and Wiseman (2009 and 2010) assess the impact of using administrative records on poverty estimation among elderly SSI recipients using the official and alternative definitions of poverty. Wiseman and Ycas (2008) compares the Canadian social assistance program for the elderly with the SSI program, looking at program structure, cost, and consequences for elderly poverty rates. Kemp (2010) conducts a descriptive analysis of the SSI student earned income exclusion. One ongoing study is examining the growth in SSI applications and awards among children. Rupp, Hemmeter, and Davies (2015) looked at SSI children by year and age at award and analyzed transitions (e.g., onto SSDI, off SSDI and SSI, mortality) as they age into adulthood. Parent, Sayman and Kulzer (2012) provides a comprehensive profile of the characteristics of disability beneficiaries with a connection to workers’ compensation or public disability benefits. Parent et al. (2012) found that 8.3 percent of disabled workers who have this connection tend to be economically better off, more frequently middle-aged, male, afflicted with a musculoskeletal and connective tissue disorder, and tend to wait longer to apply for SSDI benefits after onset than the general disabled-worker population.
Ongoing work and previously published papers by Rupp and Riley are based on a linkage of individual-level administrative data from SSA and the Centers for Medicare & Medicaid Services. First, Rupp and Riley (2011) analyzes longitudinal patterns of interaction between SSDI and SSI and finds that one quarter of the year 2000 cohort of first-ever, working-age disability awardees received benefits from both programs over a 60-month period. A second paper (Rupp and Riley 2012) analyzes the effect of longitudinal interactions between the SSDI and SSI programs in providing access to Medicare and Medicaid, and finds that SSI facilitates high levels of Medicaid coverage for SSI awardees overall and provides access to Medicaid for many SSDI awardees during the 24-month Medicare waiting period. A third paper (Riley and Rupp, 2012) tracks expenditures for 2000-2006 for the SSDI, SSI, Medicare, and Medicaid programs and finds that SSI is a relatively low-expenditure program with important implications for the other three programs. The authors conclude that SSI and Medicaid provide a temporary safety net supporting SSDI beneficiaries during their SSDI and Medicare waiting periods. Ongoing work by the authors focuses on estimated cumulative expenditure patterns over the working-age adult portion of the life cycle for the year 2000 awardees for the four programs (SSDI, SSI, Medicare, and Medicaid). An additional piece of ongoing analysis focuses on the effect of State variations in Medicaid enrollment policy and implementation regimes on Medicaid coverage and expenditures. The three State policy regimes compared include: (1) automatic enrollment of SSI awardees; (2) requiring a separate Medicaid application in “Criteria States”; and (3) more restrictive Medicaid eligibility requirements in “209B States.” Coe and Rupp (2013) analyzes whether disability benefit recipients (SSDI and SSI) in States with easier access to health insurance will be more likely to work and exit from SSDI and/or SSI than their peers in States where health insurance is more difficult to access.
In July 2012, we signed an interagency agreement with the Bureau of Labor Statistics (BLS) to test the feasibility of using the National Compensation Survey (NCS) platform to collect updated occupational information. Under our agreement, BLS will collect information about the physical, skill level, and mental/cognitive requirements of occupations as well as the environmental factors to which workers are exposed. This information will support our current disability policy and provide us with data about work in the economy to inform future policy. We signed additional agreements with BLS for fiscal years (FY) 2013 through 2015 to continue testing. In FY 2013, BLS conducted feasibility testing in three phases. After each test phase, we worked together to improve the survey tools and testing protocols. We also met periodically with DOL's Employment and Training Administration (ETA) to discuss how to incorporate elements of O*NET with the data collected by BLS. In fiscal year 2015, BLS is performing a large-scale preproduction data collection test that will conclude in the third quarter. BLS will begin collecting production data in late FY 2015. In FY 2014, we began working with a contractor to outline the requirements for the web-based platform to house the OIS, and in FY 2015, we will begin developing the platform. In late FY 2015 we will receive a limited amount of data from BLS's preproduction test to begin testing the information technology platform.
The goal of the Homeless with Schizophrenia Presumptive Disability (HSPD) Pilot Demonstration is to improve the economic well-being of adult SSI applicants who are both homeless and diagnosed with schizophrenia or schizoaffective disorder. We partnered with clinicians and case managers in California from the Health Services Agencies of San Francisco and Santa Cruz counties, the Department of Public Health of the City of San Francisco, and the Department of Mental Health of Los Angeles County, who are actively assisting their clients to navigate the SSI application process and have established relationships with patients diagnosed with schizophrenia and schizoaffective disorder who are also homeless. There were two main features of the project: (1) the SSI application assistance; and (2) the use of presumptive disability (PD). The clinicians and case managers assisted these individuals with gathering supporting medical evidence, coordinating medical appointments, and submitting the SSI application. Along with the SSI application, a Presumptive Disability Recommendation Form, created for this pilot demonstration, was also submitted. Clinicians from the community agencies certified that the applicant met the SSA criteria for a diagnosis of schizophrenia or schizoaffective disorder. To provide economic relief to the applicant while we processed the application, we awarded up to 6 months of SSI payments to the applicant based on PD. Applicants were not required to pay back these payments if we ultimately denied their applications, as long as we did not deny the applications for non-medical reasons; therefore, there must be a high degree of probability that the applicant was disabled when we conferred PD SSI payments. Our field offices generally make PD findings only for specific disability categories, which do not include schizophrenia or schizoaffective disorder.
In our evaluation, we will examine whether the program improves the administration of the SSI application and determination process. The evaluation is based on a quasi-experimental design, in which we will compare outcomes for applicants who receive assistance and PD payments with applicants from a previous period and applicants in surrounding areas. Within this framework, we plan to examine differences in initial allowance rates, appeals, failure-to-cooperate denials, processing times, total payments, exits from SSI, mortality, and the need for consultative exams. We expect to complete the evaluation by Summer 2015.
PROMISE is a joint project between SSA and the Departments of Education (ED), Labor, and Health and Human Services. The goals of the project are to improve the provision and coordination of services and supports for children with disabilities who receive SSI and their families in order to achieve improved education and employment outcomes. The targeted outcomes include completing postsecondary education and job training to obtain competitive employment in an integrated setting that may result in long-term reductions in the child recipient's reliance on SSI. In 2013, ED funded model demonstration projects in five individual States (Arkansas, California, Maryland, New York, and Wisconsin) and one consortium of States (Arizona, Colorado, Montana, North Dakota, South Dakota, and Utah) for 5 years. SSA is responsible for evaluating PROMISE.
