Abstract
The project will test the hypothesis that birth registration of unmarried adolescent girls, coupled with a phone-based system for reporting of potential child marriage cases, can lower the incidence of female early marriage in rural Bangladesh.

To test this hypothesis, the project will introduce a randomized controlled trial in 240 communities in northern Bangladesh with the following treatment arms: (i) 60 communities where the project offers, to households with unmarried adolescent girls, covering the cost of birth registration at local government digital centres; (ii) 60 communities where the project provides households with information on the Bangladesh government’s national helpline for reporting potential child marriage cases; (iii) 60 communities where the project offers to cover the cost of birth registration and provides information on the national helpline; (iv) 60 communities that serve as a control group.

The project will evaluate the effects of the intervention on the incidence of female early marriage (marriage below the age of 18), as well as school enrolment among adolescent girls, will be assessed via an endline survey conducted 9 months after the intervention has been completed.

Interventions

Intervention(s)
The study involved a two-pronged intervention targeted at rural households in Bangladesh with unmarried adolescent girls: (i) providing information, logistical support, and covering expenses, for creating or rectifying birth registration records for adolescent girls; (ii) providing information on a national government helplines for reporting child marriages.

3. Incidence of child marriage (specifical marriage below the age of 18).
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)

Experimental Design

Experimental Design
The intervention will be conducted in 240 communities in northern Bangladesh with the following treatment arms. Prior to the intervention, a listing of all unmarried adolescent girls was created for each community. Each community will be randomly assigned to one of four experimental arms as follows: (i) 60 communities where the project offers, to households with unmarried adolescent girls, covering the cost of birth registration at local government digital centres; (ii) 60 communities where the project provides households with information on the Bangladesh government’s national helpline for reporting potential child marriage cases; (iii) 60 communities where the project offers to cover the cost of birth registration and provides information on the national helpline; (iv) 60 communities that serve as a control group.
Experimental Design Details
Randomization Method
Randomisation done in office by a computer.
Randomization Unit
The unit of randomization is a community (sub-unit of a rural village).
Was the treatment clustered?
Yes

Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
We have done our statistical power calculations based on the most recent DHS data available for Bangladesh (BDHS 2014). The BDHS 2014 shows that more than 78% of children under the age of five do not have birth registration records. Using BDHS, we calculated the average cluster size (girls within the age range of 13-17 who are unmarried) is 10 children per cluster. From BDHS we calculated an Intra-cluster correlation of 0.3 and a standard deviation of 0.43. With a 95% confidence interval (alpha = -0.05), a simple power calculation with one treatment-control assignment with 80% power shows that the minimum detectable value in the treatment arm is 22.09 (compared to a mean of 22 in the control arm), which corresponds to an effect size of about 0.11 .
