THURSDAY, June 7 (HealthDay News) — Teens with major depression who
receive and respond to treatment are less likely to abuse drugs in the
following years, a new study suggests.
The study included 192 participants, aged 12 to 18, at 11 sites across
the United States who were treated for major depression and then followed
for five years. The study participants had no preexisting drug or alcohol
abuse problems.
During the follow-up, 10 percent of those whose depression receded
after 12 weeks of treatment later abused drugs, compared with 25 percent
of those who did not respond to depression treatment, the researchers
found.
“It turned out that whatever they responded to — cognitive behavioral
therapy, Prozac, both treatments, or [an inactive] placebo — if they did
respond within 12 weeks they were less likely to develop a drug-use
disorder,” study leader John Curry, a professor of psychology and
neuroscience at Duke University in Durham, N.C., said in a university news
release.
Improved control of mood due to medicine or skills learned in cognitive
behavioral therapy, along with support and education that were part of all
depression treatments, may have been important in helping prevent drug
abuse, the study authors said. Cognitive behavioral therapy is based on
the idea that a person can change their behavior by changing their
thinking patterns.
However, the researchers were surprised to find that successful
treatment of depression did not reduce the participants’ later risk of
alcohol abuse. Widespread alcohol use among people aged 17 to 23 may be a
key factor, they noted.
The investigators also found that alcohol abuse led to repeat bouts of
depression for some of the study participants.
“When the teenagers got over the depression, about half of them stayed
well for the whole five-year period, but almost half of them had a second
episode of depression,” Curry said. “And what we found out was that, for
those who had both alcohol disorder and another depression, the alcohol
disorder almost always came first.”
The study was published in the April-May issue of the Journal of
Consulting and Clinical Psychology.
Because the number of teens who developed drug or alcohol disorders was
fairly small, the study authors said more research is needed to confirm
the results.
