A study of 488 children between the ages of 7 and 17 by researchers at Columbia University in New York City looked into the effectiveness of cognitive behaviour therapy (CBT), the antidepressant sertraline (brand name Zoloft) and a combination of the two in treating childhood anxiety. One group of children was given a combination of sertraline and CBT, one group was given sertraline on its own, one group was given CBT on its own and a fourth group was given a placebo. Over the course of the 12-week study 81% of the children receiving CBT and sertraline improved, compared with 60% who received CBT alone and 55% who received sertraline alone. Among patients receiving the placebo only 24% showed an improvement.
