In a naturalistic study using routine outcome monitoring (ROM), we compare the course
of psychotherapies conducted by client-centered psychotherapists with psychotherapies
conducted by cognitive-behavioral therapists, psychodynamic psychotherapists, system
therapists, and integrative therapists, respectively. We applied a tracking procedure in which
a measure was taken at the beginning of every session. Results show that all therapists
were effective, but that clients following therapy by client-centered and system therapists
showed the biggest improvement. Behavioral therapists worked shorter with their clients
than other therapists. Additional analyses correcting for severity of complaints at the start
of the therapy did also not show differences in effectiveness between the various treatment
modalities.
