Despite the widespread use of long-term psychodynamic treatments, methodolo
gically rigorous outcome studies have not been conducted. The authors descr
ibe the results of a feasibility, Study designed to (I) investigate whether
patients in psychodynamic treatment, including psychoanalysis, could be re
cruited and retained as research subjects, (2) determine patient and therap
ist compliance with self-report measures, rater-administered structured int
erviews and session audiotaping and (3) obtain pilot data on changes in the
se measures after one year of treatment. Nine patients entering psychoanaly
sis and fifteen entering psychodynamic psychotherapy were studied at baseli
ne, six months and one year. Major findings were as follows. (1) recruitmen
t rates were 27% (psychoanalysis) and 83% (psychotherapy), (2) all patients
who reemained in treatment remained in the research protocol, (3) drop-out
rates among research participants and non-participants were equivalent, (4
) current Axis I (usually, affective or anxiety), disorders were found in o
ver 60% of patients, (5) Axis II disorders in the absence of current Axis I
disorders were rare, (6) despite a small number (N) of participants, signi
ficant positive change was demonstrated on a variety of measures after one
year. Results suggest that it is possible to demonstrate a therapeutic effe
ct of psychodynamic treatments, including psychoanalysis, but changing nega
tive clinical perceptions of research is necessary if methodologically rigo
rous outcome studies are to be possible in the future.
