Abstract
Misreporting of Intimate Partner Violence (IPV) incidence presents an important challenge for IPV research. Women may under-report IPV incidence in direct questioning surveys because of embarrassment, stigma, adverse consequences associated with reporting, and lack of awareness. We assess the validity of responses to IPV questions using three different methods. We use a experimental design to compare: (i) a face-to-face and standard questionnaire, (ii) list experiments, and (iii) a self-reported questionnaire using a ballot and a box.

Primary Outcomes
Primary Outcomes (end points)
We will measure Intimate Partner Violence incidence (IPV). Moreover we will measure IPV incidence by type (physiological, physical and sexual).

Experimental Design
Experimental Design
We will randomize survey instruments to respondents. We will randomly assign one of three Intimate Partner Violence (IPV) survey modules to compare their effectiveness to elicit IPV situations.
Randomization will be clustered within village. The experimental design will allow us to compare different IPV survey instruments and methods: (i) a face-to-face and standard questionnaire, (ii) lists experiments, and (iii) a self-reported questionnaire using a ballot and a box. A second stage level of randomization will be done if a respondent is assigned to the lists experiments to have a control and treatment group within this survey arm. The list experiment control group will receive a face-to-face and standard questionnaire about IPV.
Experimental Design Details
Randomization Method
Randomization done in office by a computer.
Randomization Unit
The randomization unit is the women and will be clustered within villages.
Was the treatment clustered?
No
Experiment Characteristics
Sample size: planned number of clusters
288 villages
Sample size: planned number of observations
8064 women
Sample size (or number of clusters) by treatment arms
2688 women will be surveyed by using a standard face-to-face domestic violence module, 2688 women will be surveyed by using self-reported module using a ballot and a box, and 2688 will be surveyed by using a list experiment, where 1344 will be assign to treatment and 1344 to control.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
