Abstract
Adolescence and young adulthood are formative periods for sexual and reproductive health and emerging autonomy. During this period, young people navigate changing social roles and relationships, including expectations around gender and sexuality and ideas about what constitutes acceptable behavior. Social approval and perceived expectations may therefore shape not only how young women feel able to express their own views, but also whether they feel able to act on those views when engaging with sensitive topics such as contraception. Importantly, individuals respond to the social environment as they perceive it, which may differ from the underlying distribution of attitudes in that environment. Such discrepancies may lead individuals to make decisions partly on the basis of inaccurate perceptions of what others think or consider acceptable, even when these perceptions differ from their own preferences. In our study communities in Ghana and Burkina Faso, young people report high levels of acceptance of a young woman’s use of modern contraception if she wishes, but substantially underestimate the level of acceptance reported by other young people in the same cohort. We conduct an individually randomized survey experiment among adolescent girls and young women, embedded in an ongoing cohort study. Treated participants receive a short, site-specific video providing information about the measured share of young people in their community who support a young woman’s ability to use modern contraception if she wishes. We examine whether this information changes women’s social and health-seeking engagement with contraception and, among sexually active women for whom contraceptive behavior is immediately relevant, intentions to use contraception.

Interventions

Intervention(s)
The intervention is a survey-embedded information experiment. Eligible female adolescents and young women aged 13 or older are randomly assigned to either treatment or control group. Participants assigned to the treatment group watch a short video providing truthful information about attitudes toward young women’s contraceptive use among young people in their own community. Specifically, the video reports the measured proportion of young women and men in the study population who agree that a young woman should be able to use a modern contraceptive method if she wishes. This statistic is based on responses collected in an earlier wave of the same cohort and is presented to participants as a community-level statistic.
The video visualizes the statistic to facilitate comprehension, and is shown to participants on a tablet during the survey interview. Because measured attitudes differ between the two study sites, site-specific versions of the video are produced for Nouna (Burkina Faso) and Ningo-Prampram (Ghana). Each version reports the corresponding statistic for that site and is translated into the relevant local language. Participants assigned to the control group do not receive the information video and proceed directly to the subsequent survey questions.

Primary Outcomes

Primary Outcomes (end points)
The primary outcome is an equally weighted composite index constructed from five standardized measures capturing (i) comfort discussing contraception with a friend, (ii) willingness to advise a friend who is considering modern contraception to obtain a contraceptive, (iii) comfort going to a health center to obtain a contraceptive method if needed; (iv) comfort asking a health worker or nurse for contraceptive or family-planning advice; and (v) willingness to participate in a group discussion about acceptance of contraception.
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
- Individual components of the contraception-related social and health-seeking engagement index
- Intention to use contraception during next sexual intercourse
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
We conduct a survey experiment embedded in an existing cohort in two Health and Demographic Surveillance System (HDSS) sites: Nouna, Burkina Faso and Ningo-Prampram, Ghana. Female adolescents and young women that meet the eligibility criteria of being 13 years of age or older are randomly assigned in a 1:1 ratio to either a treatment or control group, with randomization conducted separately within each HDSS site.
The experimental structure is as follows. First, prior to exposure to the treatment, we elicit participants’ prior second order beliefs about the attitudes of other young people in their cohort toward young women’s contraceptive use. Second, participants receive their randomly assigned treatment. Those assigned to the treatment group watch the information video, while those assigned to the control group proceed directly to the subsequent survey questions. Third, participants in both arms complete an identical outcome module, in which contraception-related measures are embedded within a broader set of questions on health-seeking and health-related discussions. Finally, both groups complete the post-outcome module.

Randomization Method
Individuals are randomized using computer-generated random assignment from the available cohort roster.
Randomization Unit
Randomization is conducted at the individual level independently within each HDSS site.
Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of clusters
Not applicable. No clusters.
Sample size: planned number of observations
The study is embedded in an existing cohort, and the planned sample size corresponds to all eligible study participants in the cohort: N = 1,630 female adolescents and young women aged 13 or older, with N = 896 in Ningo-Prampram, Ghana, and 734 in Nouna, Burkina Faso.
Sample size (or number of clusters) by treatment arms
Participants will be assigned to the treatment or control group with equal probability. Given the planned total sample size of N = 1,630, approximately 815 participants will be assigned to each treatment arm.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Considering the planned sample size of N = 1,630, individual-level randomization with 1:1 allocation within each HDSS site, and assuming a significance level of α = 0.05 (two-sided) and 80% power, the minimum detectable effect for our primary outcome index is approximately 0.14 standard deviations.
