Abstract
Our study uses a randomized controlled trial (RCT) to evaluate the effectiveness of a mass media campaign (radio) designed to reduce pregnancy rates among Hispanic teens. The coverage areas of 28 FM radio stations (mostly Spanish-language) in California are included in the study. We randomly assigned 14 of the 28 radio stations to the treatment group and asked each treatment group radio station to air a 30-second ad 15 times per week for five weeks. In the ad, a young woman stressed the opportunity costs to teen mothers of having a baby (e.g., missed opportunities for fun, socializing with friends, or attending school). The study will estimate the effects of the intervention on births to female Hispanic teenagers in the year after the ad was aired, using birth records from the California Department of Public Health.

Primary Outcomes
Primary Outcomes (end points)
For each of the 28 radio station coverage areas, our primary outcome is the number of births from Jan. 19, 2016 (5.5 months after the first airing of the ad) to Sept. 14, 2016 (10 months after the last airing) to Hispanic females age 20 or younger, divided by the number of births from Jan. 18, 2015 to Sept. 14, 2015 to Hispanic females age 20 or younger.

Experimental Design Details
Randomization Method
Randomization done in office by a computer
Randomization Unit
The unit of randomization is the radio station. (Since the data for estimation of treatment effects will consist of one observation for each radio station's coverage area, we have not classified the treatment as clustered in our answer to the next question.)
Was the treatment clustered?
No
