Psychotherapy and pharmacotherapy randomized controlled trials are equally likely to report a positive outcome.

A very high proportion of controlled trials of psychotropic drugs report a positive outcome. To determine if the population of positive outcome in psychotherapy trials is as high as reported, a cohort of consecutive randomized controlled trials published in four internal psychiatry journals over a five-year period were analyzed. Chi square test and descriptive analysis were conducted. A total of 237 trials were included. Out of 188 pharmacotherapy trials, 164 (88%) reported a positive outcome. Out of 49 psychotherapy trials, 44 (90%) reported a positive outcome. The difference between above reported population was not statistically significant on chi-square test (p=0.626). It was concluded that positive outcome reports in published psychotherapy trials are as common as in pharmacotherapy trials.
