For both IPV outcomes, women were less likely to provide discrepant reports if they had recent IPV at baseline, poor mental health (T53) and poor communication with partner (T53). 73% of women reported lifetime physical IPV, and 55% lifetime sexual IPV in at least one survey round. Among 93 (31%) with lifetime history of sexual IPV at T0, 73% provided a subsequent discrepant report. At T0, 154 (51%) women reported lifetime history of physical IPV, of whom 62% gave a discrepant ‘never’ report in a subsequent round. We use logistic regression to explore associations between discrepant reporting and respondent baseline characteristics, the nature of their IPV experiences at baseline, and situational factors at T53.Ĭomplete IPV data were available for 301 women. Among those reporting lifetime history of IPV at T0, we calculate the proportion who subsequently report no lifetime history at T29 and/or T53 (‘discrepant’ reporting).

We use data from the control group of the cluster randomised trial and a follow-on longitudinal study in Tanzania to examine discrepancies in women’s reported experience of lifetime physical IPV and sexual IPV over three time-points (T0, T29, T53 months). Research to understand the extent, causes and consequences of IPV relies on self-reported data on violence, and yet there is a paucity of research into the consistency with which women report lifetime IPV over time. Intimate partner violence (IPV) against women is pervasive throughout the world, with profound consequences for women’s health. Nonverbal response cards offer a practical and beneficial method for reducing underreporting of stigmatized and traumatic experiences while maintaining data quality in low-literacy populations.
These differences were broadly similar across sample subgroups defined by age, gender, proneness to social desirability, and mental health. Nonverbal respondents reported similar patterns of physical assault and sexual debut as verbal respondents but significantly higher levels of sexual assault and forced sex. The level of internal reliability of responses among nonverbal respondents was similar to or greater than that of verbal respondents. We first evaluated response validity and reliability in each arm, then compared prevalence rates across arms and evaluated whether any differences varied by respondent characteristics using regression models. We randomized participants to either a conventional verbal response arm or a nonverbal response card arm where respondents' answers were unspoken and not displayed to interviewers. We tested a low-tech nonverbal response card that avoids revealing interviewees' responses to interviewers while retaining interviewer support among adolescents in communities with very low educational attainment.Īs part of a broader health questionnaire, we asked a sample of 1,644 adolescents, aged 12–20 years, in northwestern Burkina Faso about their experiences of physical and sexual violence. Most methods that attempt to reduce such biases require literacy and either remove the benefits of interviewer guidance or do not give individual-level results. Accurate measures of violence are difficult to obtain from self-reported data because of stigmatization and social undesirability of the topic.
