Abstract

Dr. Ougrin’s evaluation of cognitive therapy versus exposure in anxiety disorders reported a standardised mean difference SMD 95% confidence interval CI of 0.52 0.37, 0.74 for short-term outcomes and 0.46 0.29, 0.73 for long-term outcomes in social phobia, and 0.88 0.69, 1.11 for short-term outcomes and 1.05 0.80, 1.37 for long-term outcomes in posttraumatic stress disorder PTSD. These were incorrectly meta-analysed. Upon re-analysis, we found that the correct SMD 95% CI was −0.66 −1.19 -0.14 for short-term outcomes and mean difference 95% CI of −29.66 −46.13 -13.19 on the Social Phobia subscale from the Social Phobia Anxiety Inventory for long-term outcomes in Social Phobia. For PTSD, the SMD 95% CI for short-term outcomes was −0.13 −0.36, 0.11 and 0.05 −0.22, 0.32 for long-term outcomes. However, correcting the errors did not change the interpretation of the findings considerably.
