Abstract:

The National Survey of SSI Children and Families (NSCF) collected data about families with children with disabilities who have applied for Supplemental Security Income (SSI) since 1992. The NSCF supports descriptive analysis of the characteristics of current beneficiaries and their families and studies the effects of welfare reform. The national sample consisted of 11,971 children drawn from Social Security Administration (SSA) files and 9,243 responded. The completion of an interview has basically two stages: (1) to locate the sample case and (2) to obtain the cooperation of the sample case. To compensate for nonresponse, we used two logistic regression models. The first model predicted the probability of locating the sample case. And the second model computed the probability of response among located sample cases. The SSA files provided personal characteristics of the SSI applicant, personal characteristics of the person responsible of the applicant, demographics, and previous SSI benefits received. We will show the effects of including personal characteristics of the person responsible of the children to improve the nonresponse adjustments.
