This paper describes the work done with a group of patients with chron
ic schizophrenia (N = 33) in an activity therapy treatment program, us
ing music therapy and expressive movement therapy. The program lasted
14 months. The sample was divided into an experimental (n = 17) and a
control (n = 16) group. Both groups had similar diagnostic and sociode
mographic characteristics. Patients were evaluated before and after th
e treatment program, with the Therapy Intake Assessment for Psychiatri
c Patients (7). The results of both groups were compared, and no signi
ficant statistical differences were found after the therapeutic interv
ention. Nevertheless, when individual scores for each scale of the que
stionnaire were analyzed (self concept, interpersonal relationships, a
ltruism/optimism and leisure time use), a higher number of patients of
the experimental group showed an increase in the scores of 3 out of t
he 4 of scalps. Subjects of the control group increased their score in
one of the scales. During the clinical work, patients showed improvem
ent in their social skills and interaction, and in the use of leisure
time, although these changes were not shown in the Assessment Instrume
nt. This paper proposes that adequate forms of clinical evaluation are
to be used or created for music therapy and creative movement therapy
interventions, so that the changes shown by the patients can be repor
ted and therefore considered as part of a clinically successful progra
m.
