Addition of cognitive
behavioral therapy to drug treatment of pediatric obsessive-compulsive
disorder improves symptoms
Children and teens with obsessive-compulsive
disorder (OCD) who were receiving some benefit from treatment with
medication had a significantly greater reduction in OCD symptoms
with the addition of cognitive behavior therapy (CBT), according
to a study in the September 21 issue of JAMA.
"Obsessive-compulsive disorder affects up to 1 in 50 people,
is evident across development, and is associated with substantial
dysfunction and psychiatric comorbidity. Randomized controlled trial
findings support the efficacy of pharmacotherapy with serotonin
reuptake inhibitors (SRIs), cognitive behavior therapy involving
exposure plus response prevention, and combined treatment. However,
a paucity of expertise in pediatric OCD prevents most families from
accessing exposure plus response prevention or combined treatment.
Outcome data for pharmacotherapy alone, the most widely available
treatment indicate that partial response is the norm and clinically
significant residual symptoms often persist even after an adequate
trial," according to background information in the article.
Martin E. Franklin, Ph.D., of the University of Pennsylvania School
of Medicine, Philadelphia, and colleagues conducted a study to examine
the effects of augmenting SRIs with CBT or a brief form of CBT,
instructions in CBT delivered in the context of medication management.
The 12-week randomized controlled trial was conducted at 3 academic
medical centers between 2004 and 2009, involving 124 outpatients
between the ages of 7 and 17 years with OCD as a primary diagnosis.
Participants were randomly assigned to 1 of 3 treatment strategies
that included 7 sessions over 12 weeks: 42 in the medication management
only, 42 in the medication management plus instructions in CBT,
and 42 in the medication management plus CBT; the last included
14 concurrent CBT sessions.
The researchers found that at 12 weeks the percentages of participants
who had at least a 30 percent reduction in their Children's Yale-Brown
Obsessive Compulsive Scale baseline score were 68.6 percent in the
plus CBT group, 34.0 percent in the plus instructions in CBT group,
and 30.0 percent in medication management only-group. Comparisons
showed that the plus CBT strategy was superior to both the medication
management only strategy and the plus instructions in CBT strategy.
The plus instructions in CBT strategy were not statistically better
than medication management only.
The researchers add that the findings from this and other studies
highlight the importance of disseminating CBT for pediatric OCD
into community settings so that affected children have options beyond
medication management alone. "Furthermore, [the findings from
this study] indicate that these dissemination efforts should focus
on making the full CBT protocol more widely available in such settings
rather than on attempting to create and disseminate truncated versions
of this efficacious form of treatment. Toward these ends, research
must focus on developing, evaluating, and comparing various models
for disseminating CBT beyond the academic medical context."
