The aim of this study was to investigate whether multisite sampling increased heterogeneity among a sample of cocaine users
from São Paulo, Brazil. Six hundred and fourteen cocaine users were interviewed at 23 fixed sites plus an out-of-treatment sample,
The sites \Vere then regrouped into six main types: uni\’ersity outpatient cJinics, public outpatient cJinics, pubJic inpatient units.
private inpatient units. HIV services and non-treatment. Marked differences \Vere found belween users recruited at lhese sites,
especial!y in re!ation to age, gender, empJoyment status, criminal history, history of prostitution, previous drug misuse treatment,
duration of cocaine USe and lifetime use of intravenous cocaine. These results suggest that multisite sampling is a valid melhod
for increasing patient heterogeneity, but whether it improves representativeness and thus lhe generalisability of drug misuse”,
research is debatable .. ~ 2001 Elsevier Science Ireland Ltd. Ali rights resel’\ed.
