Abstract
Women in poor nations often have poor menstrual hygiene. We are testing whether an intervention within rural self-help groups can address these challenges. Specifically, we study
1. Can free trials can increase uptake of menstrual cups?
2. Do free trials by peers (which we hypothesize will increase uptake) increase cup uptake by peers who did not receive a free trial?

Experimental Details

Interventions

Intervention(s)
We will market menstrual cups to JVK women's group meetings in rural Karnataka. These meetings already exist and have discussed menstrula hygiene management in the past.

We will offer cups for sale.

At half the meetings we will also offer free trials. Half the women (chosen by lottery) who volunteer for a free trial will receive one. Free trial recipients must either pay for the cup within 3 months or return it for disposal (and owe nothing). We invite (but do not require) free trial recipients to describe their experience with the cup.

Experimental Design

Experimental Design
Randomize which women's group meetings get free trials.
If multiple women volunteer for a free trial: Randomization of which women receive the free trial.
Experimental Design Details
Not available
Randomization Method
The PI will randomize women's meetings.
Within a meeting, women interested in a free trial pull numbers from a hat to see who gets a free trial.
Randomization Unit
JVK women's meetings are the main randomization
Within a meeting, women interested in a free trial are the unit of randomization
Was the treatment clustered?
Yes
