Followed-up 51 male patients with hospital diagnoses of schizophrenia in the military service through VA hospital records 20 yrs after their initial service hospitalization. Results reveal that severity of thought disorder did not predict outcome, but measures of affectivity and interpersonal competence did so with high significance. The question of why affectivity has received so little attention in the research literature is addressed. It is suggested that recent research diagnostic criteria for schizophrenia are inadequate, because the criteria focus almost exclusively on the less predictive symptoms of disordered thought and exclude assessment of affectivity and interpersonal competence.
