E. Hamera et al., INTERNAL AND EXTERNAL ENVIRONMENT OF INDIVIDUALS WITH SCHIZOPHRENIA DURING ALCOHOL AND DRUG-USE, Archives of psychiatric nursing, 10(3), 1996, pp. 136-142
Explanations for the high prevalence of alcohol and drug abuse in schi
zophrenia purport that substance use is related to social-affiliative
needs or to symptom regulation, Neither explanation was adequate in de
scribing substance-use episodes in the present longitudinal study. The
study involved repeated interviews of 10 individuals with schizophren
ia about their internal and external environment during substance use.
Qualitative analyses of interview responses showed variability in mul
tiple versus single episodes in a day and categories labeled Activitie
s Prior to Use and Social Context of Use. Individual subject's respons
es each had a unique pattern that characterized their substance-use ep
isodes. (C) 1996 by W.B. Saunders Company
