Army induction scores on the Armed Forces Qualification Test were available on 50 acute schizophrenics, 30 chronic schizophrenics, and 50 enlisted men. The Army General Classification Test was administered to the acute schizophrenics within 1 wk. after being hospitalized for schizophrenia, to the chronic schizophrenics up to 20 yr. after their first hospitalization for schizophrenia and to the enlisted men some time after induction. Difference scores were computed for all Ss by subtracting the standard test score of the AGCT from the standard score of the AFGT received at induction. The three groups were matched on education and test performance at induction. At the second testing, both acute and chronic schizophrenics scored significantly below controls. However, the chronic schizophrenics were not differentiated from the acute schizophrenics on test performance. Results suggested differential deficit in chronic schizophrenics but not in acute schizophrenics. Implications for further research were drawn.
