Notes: The regressions are stratified by whether the respondent received or did not receive SSDI/SSI in the year prior to applying for VR services. The coefficient estimates reveal the association between VR and SSDI/SSI receipt. The sample is comprised of 51,155 quarterly post-applications observations for the subsample of cases receiving SSDI/SSI in the year prior to VR application and 208,812 observations in the subsample of cases not receiving SSDI/SSI prior to the VR application. The covariates are listed in Table 1.
a. Respondents receiving DI in all four quarters prior to the VR application (N = 1,266).
b. Respondents not receiving DI in any of the four quarters prior to the VR application (N = 5,163).
c. The regressions include the covariates listed in Table 1.
* = statistically significant at the 5% level.
