J. Derisley et S. Reynolds, The transtheoretical stages of change as a predictor of premature termination, attendance and alliance in psychotherapy, BR J CL PSY, 39, 2000, pp. 371-382
Objective. The Transtheoretical Model proposes that clients' stage of chang
e will predict their engagement in therapy. This study tested the hypothese
s that clients with high Precontemplation scores would prematurely terminat
e from therapy and that clients with high Action scores would attend a grea
ter number of sessions and establish a more positive therapeutic alliance.
Design. Using a within-subjects design, baseline measures of stage of chang
e were used to predict the number of sessions attended, premature drop-out
from therapy, and the therapeutic alliance after sessions one and three.
Methods. Sixty clients completed the Stages of Change Scales and the Brief
Symptom Inventory prior to therapy. The therapeutic alliance was assessed a
fter the first and third therapy session using the Agnew Relationship Measu
re.
Results. The specific hypotheses were not supported. Premature termination
from therapy was predicted by high level of initial symptom severity and lo
w Contemplation scores. Positive therapeutic alliance at session one and se
ssion three was predicted by high Contemplation at baseline.
Conclusions. These results suggest that the Transtheoretical Model, which w
as developed in the context of interventions for behavioural change, may no
t be directly generalizable to outpatient psychotherapy populations. Howeve
r, Contemplation did predict premature termination and engagement. This imp
lies that with adaptation the model may be a useful adjunct to psychotherap
y assessment.
