Objective: The outcome of a day treatment program for psychiatric outp
atients with affective and pesonality disorders was evaluated. The pro
gram was dynamically oriented, intensive, group focused, and time limi
ted (18 weeks). Methods. The prospective trial used a randomized treat
ment-versus-control (delayed-treatment) design to examine 17 outcome v
ariables covering five areas. interpersonal functioning, symptomatolog
y, self-esteem, life satisfaction, and defensive functioning. Those va
riables, plus individualized treatment objectives, were monitored befo
re and after the treatment and control periods and at follow-up an ave
rage of eight months later. Results: Treated patients showed significa
ntly better outcome than control patients for seven of the 17 outcome
variables: social dysfunction, family dysfunction, interpersonal behav
ior, mood level, life satisfaction, self-esteem, and severity of distu
rbance associated with individual goals of treatment as rated by an in
dependent assessor. The findings could not be accounted for by diagnos
is or use of medication. Benefits were maintained over the follow-up p
eriod. The average treatment-versus-control effect size for all 17 var
iables was .71. Conclusions: The study supports the efficacy of an int
ensive day treatment program for patients who manifest significant dif
ficulties associated with affective and personality disorders.
