Cognitive-behavioral therapy (CBT) is an effica-
cious first-line therapy for patients with major
depressive disorder (MDD). Due to the limited
accessibility of CBT, long wait lists result in
delayed treatment, which may affect treatment
outcomes. The goal of this pilot study was to
obtain preliminary data from a randomized con-
trolled trial to determine whether delayed CBT
reduces the effectiveness of the therapy com-
pared to immediate CBT in patients with MDD
receiving pharmacotherapy. Patients were ran-
domized to receive immediate CBT (n = 18) or to
begin CBT after 6 months (n = 20) and received 14
weekly sessions, followed by two additional
booster sessions. During the active treatment
months, patients in the immediate group demon-
strated reductions in scores on the Beck
Depression Inventory II (BDI-II) that were simi-
lar to those in the delayed CBT group. However,
when the analysis was performed using only
data from patients in the delayed group who
were still in a depressive episode, there was an
overall greater decrease in BDI-II scores in the
immediate group vs. the delayed group over the
active treatment months, but not specifically at
the 6-month endpoint. These findings suggest
delays in depression treatment, similar to what
occurs with real-world wait list times, may not
have a significant impact on the effectiveness of
CBT in patients who are already receiving treat-
ment as usual. However, such delays may affect
the effectiveness of CBT in those patients who
remain depressed during the time delay. A larger
trial is necessary to confirm these findings.

of life
Major depressive disorder (MDD) results in signifi-
cant functional impairment, which can affect indi-
viduals’ ability to work and perform regular
activities.

Although the mainstay of treatment is
typically pharmacotherapy, issues such as medica-
tion adherence, failure to achieve remission, and tol-
erability can limit the use of antidepressants in this
population, thereby increasing the risk of relapse.

Evidence-based adjunctive psychotherapies such
as cognitive-behavioral therapy (CBT), a time-limit-
ed psychotherapy, improve remission rates in
patients with mood disorders as well as those with
anxiety and eating disorders.

CBT can be as effec-
tive as antidepressant treatment during the acute
phase of MDD for patients with mild to moderate
depression,

while adolescents and patients with
chronic/severe MDD demonstrate greater benefit
from a combination of pharmacotherapy and
CBT.
14–16
In addition, evidence suggests that CBT
has a greater protective effect against relapse than
pharmacotherapy.

Lack of timely access to CBT is a global issue.
20–22
In the United States, psychotherapy-based visits by
psychiatrists for MDD and anxiety disorders
decreased from 44% in 1996–1997 to 29% in
2004–2005, largely due to an overall decrease in psy-
