A prior study in a US state hospital suggested that schizophrenia is more closely associated with tobacco smoking when compared with other severe mental illnesses. This second study, in a neighborhood hospital, tries to (1) replicate that schizophrenia is associated with smoking and heavy smoking, and (2) rule out that this relationship is explained by(More)

This study, in another US hospital, attempts to (1) replicate that schizophrenia and smoking are associated with polydipsia, and (2) rule out that this relationship is partly explained by alcohol and drug use. Both studies(More)

Nine repetitive behaviors from the Elgin Behavioral Rating Scale were assessed in 400 schizophrenia(More)

We evaluated two qualitatively different estimates of premorbid intelligence in a sample of schizophrenia patients and tested whether: (1) the two indices were related and produced similar IQ estimates, and (2) either(More)
Many previous prevalence studies of polydipsia (PD) have utilized single and often non-biologic measures. In this study we estimated prevalence using specific gravity of urine (SPGU), normalized diurnal weight gain (NDWG), and staff identification (staff ID). Agreement between these two biologic and one behavioral measure was assessed. A total of 572(More)
