Two attitudinal scales measuring commitment to abstinence-oriented tre
atment policies and disapproval of illicit drug use were derived from
a survey of 90 staff working in 10 public methadone maintenance clinic
s in Sydney, Australia. The two scales were shown to be valid construc
ts by confirmatory factor analysis and to be internally reliable and t
o have high test-retest reliability. The factors underlying the two sc
ales were highly correlated (r = .77), indicating support for policies
that enforce abstinence and limit the duration of maintenance is high
ly associated with personal disapproval of drug use. There was no sign
ificant correlation between staff's knowledge of the benefits of metha
done maintenance and their support for abstinence-oriented policies.
