Title: Race, personal history characteristics, and vocational rehabilitation outcomes : a structural equation modeling approach
Author: Martin, Frank H.
Abstract: Numerous studies have indicated racial and ethnic disparities in the vocational rehabilitation (VR ) system , including differences in eligibility , services provided , and employment outcomes . Few of these studies , however , have utilized advanced multivariate techniques or latent constructs to measure quality of employment outcomes (QEO ) or tested hypothesized models for the relationship between race , personal history characteristics , and VR outcomes . Furthermore , few VR disparities studies have examined southwestern states such as Texas , which has large Hispanic and Black populations . The purpose of this study was to utilize structural equation modeling (SEM ) to examine several implied conceptual models for the relationship between race , personal history characteristics , and VR outcomes for White , Black , and Hispanic participants in the Texas VR system . The implied conceptual models were tested for goodness of fit and multiple -group invariance . A measurement model for QEO , a latent construct , was tested and used in the study . QEO was measured by three indicator variables and evaluated using confirmatory factor analysis . A MIMIC model was tested to assess racial /ethnic variation in QEO . The MIMIC results were compared to a multiple regression approach . In addition , a path model and logistic regressions were conducted to assess racial variation in VR closure status among consumers who were unemployed at application to VR . All models were retested with an independent sample to assess predictive validity . The study results indicated good model fit and measurement invariance for the QEO construct . The structural model for race , personal history characteristics , and QEO indicated moderate model fit . It also indicated interaction effects for race by gender and for race by public support . The MIMIC model results suggest that QEO decreased for Blacks and Hispanics compared to Whites . Furthermore , the MIMIC results , which utilized QEO as an endogenous variable , differed from the multiple regression findings , which utilized one criterion . The multiple regression findings indicated no statistically significant difference between Blacks and Whites . The path model for race and VR closure status indicated poor model fit . The logistic regression indicated no racial /ethnic differences in VR closure status . Several model estimates did not cross -validate . Study limitations and suggestions for future research are described .
