Adherence to recommended services is essential for long-term effectiveness
of ambulatory treatment programs, hut factors associated with such adherenc
e are not securely established. We evaluated attendance at 896 scheduled ps
ychiatric clinic visits for 62 patients at a major psychiatric teaching hos
pital, Visit adherence was found to be significantly higher among patients
in an acute stage of illness, those with a personality disorder, those with
a post-high-school education, and those living alone. Adherence was also h
igher when visits were routinely scheduled, when the intervisit interval wa
s shorter, and when the visit entailed psychotherapy rather than pharmacoth
erapy.
