1. A rating scale was devised for evaluating chronic mental patients.2. By using this rating scale and certain other criteria, 19 sets of 5 carefully matched chronic schizophrenics were formed. Five groups of 19 patients each were randomly formed to compare the results of REST, REST plus group psychotherapy, chlorpromazine, and chlorpromazine plus group psychotherapy. One group contained matched controls.3. REST was followed in 6 months by a significant lowering in rating score in comparison to the control group.4. Weekly group therapy among REST patients restored them to a pre-treatment level.5. Chlorpromazine resulted in a significant improvement in rating score in comparsion to the matched control group. Weekly group therapy resulted in slightly greater improvement, but it was not statistically significant.Abstract Teaser
