Abstract The project designed and implemented list experiments to measure the incidence of domestic violence among rural women in Peru. The project designed and implemented list experiments to measure the incidence of intimate partner violence among women in Peru.

Study Withdrawn No
Intervention Completion Date August 25, 2015
Data Collection Complete Yes
Final Sample Size: Number of Clusters (Unit of Randomization) Final sample: 1078 women (randomization was done at the individual level)
Was attrition correlated with treatment status? No
Final Sample Size: Total Number of Observations From the total pool of 1873 clients in 112 village banks in ADRA's microcredit program in Lima, we first drop all clients under age 18 as well as all women above 65. This leaves us with a universe of 1776 clients. We draw 6 banks at random and exclude them from the study to be able to pilot the instruments with their members. The remaining universe is comprised by 1690 clients in 106 banks. Finally, we work with all banks with monthly meetings scheduled during July 2015, which restricts the population of interest to 1562 women in 98 village banks. We targeted this restricted universe and were able to interview 1223 women between July 1st and August 25th, 2015. Randomization of the treatment was done at the individual level and was conducted by the surveyor. The questionnaire was implemented via tablets. Due to some initial complications with the software, we drop a few surveys which were incorrectly assigned to answer the list experiment questions from both treatment arms and are left with a sample of 1078 valid surveys.

Experimental Design (Public) We randomly assigned bank clients to two arms. In the first arm, the control group, women were asked about three sets of statements without the sensitive questions. The sets contained 4 questions each. In the second arm, the treatment group, the sets had one extra question. These additional (and sensitive) questions were about sexual and physical violence. As described above, the participants answered how many statements were true and not which were true. To measure the incidence of violence in the control group, we use a DHS-style set of questions. We randomly assigned bank clients to two arms. In the first arm, the control group, women were asked about four sets of statements without the sensitive questions. The sets contained 5 questions each. In the second arm, the treatment group, the sets had one extra question. These additional (and sensitive) questions were about sexual and physical violence. As described above, the participants answered how many statements were true and not which were true. To measure the incidence of violence in the control group, we use a DHS-style set of questions.
Randomization Method Three balls (2 white and one blue) were included in a black bag. The enumerator asked the bank client to extract (without looking) one ball. If blue, women were assigned to the treatment group, otherwise they were in the control. Two balls (one white and one blue) were included in a black bag. The enumerator asked the bank client to extract (without looking) one ball. If blue, women were assigned to the treatment group, otherwise they were in the control.
Planned Number of Clusters There are 151 banks. However, as described elsewhere, randomization was conducted at the individual level. There are 112 banks. However, as described elsewhere, randomization was conducted at the individual level.

Paper Abstract A growing literature seeks to identify policies that could reduce intimate partner violence. However, in the absence of reliable administrative records, this violence is often measured using self-reported data from health surveys. In this paper, an experiment is conducted comparing data from such surveys against a methodology that provides greater privacy to the respondent. Non-classicalmeasurement error in health surveys is identified as college-educated women, but not the less educated, underreport physical and sexual violence. The paper provides a low-cost solution to correct the bias in the estimation of causal effects under non-classical measurement error in the dependent variable.
