The project was designed to demonstrate the feasibility and effectiveness of providing faster, more relevant, and more comprehensive diagnostic services to vocational rehabilitation clients with a wide range of disabilities. The improved services were provided by an Experimental Unit (E) and compared with those of a Control Unit (C). The random assignment of physically disabled, alcoholic, mentally ill, and mentally retarded clients to E and C groups and procedures used for each group are presented. The following components used with E referrals are described: audiovisual orientation, vocational rehabilitation-oriented social evaluation interview, psychological testing, short-term work evaluation, faster general medical examination, medical transcription, and transportation. Thirteen variables on which it was hypothesized that the E Group would be found superior to the C Group are listed. Results, based on 749 E and 722 C cases, are reported in 20 tables (Appendix A) and analyzed in narrative form. Findings revealed successes in some areas but indicate that, in general, all E-C differences were small. A discussion section presents comparisons between the groups and seven recommendations for further endeavors. Also appended are forms used in the Experimental unit and counselor questionnaire responses. (Author/MS)
