We examine associations between partner-related variables (i.e., partner's
economic support, drug use, treatment experience, and recent partner confli
ct) and treatment motivation (i.e., drug use problem recognition, desire fo
r help, and treatment readiness). Participants were 266 cohabiting or marri
ed individuals recruited from STD clinics, emergency rooms, and jails in Lo
s Angeles County between 1992 and 1994, who reported recent drug use. Multi
variate analyses show that for men, partner-related variables are not stron
g predictors of motivation. For women, however, several partner-related var
iables significantly predict motivation. Having a partner who has been in t
reatment increases the odds of women's desire for help and treatment readin
ess, and having a partner who uses drugs decreases the odds of women's trea
tment readiness. For both men and women, deriving a greater amount of incom
e from self sources than from a partner is associated with increased treatm
ent motivation.
