Researching people with depression always poses challenges. Our task to recruit adults between the ages of 34 and 64 with major depressive disorder across two protocols wasn’t going to be easy. Especially since only 75% of the expected sites were being activated.


Our communications included print and radio advertising and site recruitment tools, which directed more than 8,000 unique visitors to the study website. Enrollment for both protocols was achieved ahead of schedule – by nine and six months, respectively. Considering direct cost savings alone, the return on investment for the sponsor totaled more than $19 million. In addition, our retention campaign achieved a 91% success rate.
