An interventional study of Social marketing activities in Contraceptive Behavior, Pregnancy (Unwanted) and Personal Autonomy, sponsored by Guttmacher Institute. Not yet recruiting. Open to female participants aged 15 Years to 49 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-11-10.
Sponsored by Guttmacher Institute · Not applicable, Interventional, and Health services research
The goal of this randomized controlled trial in Southern Chad is to learn if family planning social marketing activities can improve sexual and reproductive health, education and empowerment among women aged 15-49 years old. Planned activities include health provider training, partnership with private clinics, community midwife outreach, support to private pharmacies and retailers, and activities to raise awareness of family planning among the general population. The main questions it aims to answer are:
Researchers will compare women living in the areas receiving the social marketing intervention activities (intervention arm) to women living in areas not receiving these activities (control arm) to see to what extent health and empowerment outcomes differ between the two arms.
In intervention areas, the implementing partner DKT International will conduct the following activities:
This randomized controlled trial is an independent evaluation of the social marketing organization DKT International's family planning activities in two Southern provinces of Chad. This trial is part of the Family Planning Impact Lab (FPIL), a five-year research initiative to generate new experimental evidence of the longer-term health, wellbeing, and development outcomes and on the cost-effectiveness of family planning interventions, which includes three randomized controlled trials evaluating family planning interventions in underserved settings in sub-Saharan Africa (RCT1: Chad; RCT2: Somalia and South Sudan; RCT3: Sierra Leone).
Chad is one of the most disadvantaged countries in the world, with 84% of people experiencing multidimensional poverty. Women and girls are disproportionately impacted, with lower educational attainment than boys, and an average age at first marriage of 16 years. Chad has the second highest maternal mortality ratio in the world at 748 deaths per 100,000 live births (2023), as well as higher neonatal and child mortality, and a fertility rate over six children per woman. About 23% of pregnancies are unintended, 29% of which end in abortion. In 2019, the modern contraceptive prevalence rate was estimated at 6.7% among women in union and 7.7% among unmarried sexually active women, with over 30% of married women and 68% of unmarried sexually active women wanting to either delay or limit their births but not currently using a modern method.
Additional investment in the private sector has the potential to provide necessary family planning services that fill existing gaps, under the assumption that people (even in resource-constrained environments) are willing to pay for those services. DKT International is a global non-profit organization working in more than 90 countries across Africa, Asia, and Latin America. They focus on registering a full range of contraceptive and safe abortion products in countries and distributing them through private sector channels, training health providers, and increasing demand for family planning through high-impact mass media marketing activities (billboards, television, radio, and online) and call center support. DKT's Francophone West and Central Africa team delivered over 1.7 million couple-years of protection in the region in 2025. They began operating in Chad in 2022, mostly in the capital city of N'Djamena.
In order to support the availability of additional family planning services in other areas of Chad, DKT will implement a set of programmatic activities in the two Southern provinces of Logone Occidental and Mandoul. These activities will focus on ensuring that health care providers are trained on the full range of family planning methods, that commodities are consistently available at facilities and through pharmacies and retailers, and training a cadre of community-based midwives to provide family planning to women outside of facilities. Additionally, DKT will implement demand generation activities, including mass media advertising, community events, and outreach by community health workers.
This 4-year study will use a two-arm randomized controlled trial design to assess the impact and cost-effectiveness of DKT's activities in the two provinces. Health districts containing randomized private facilities in the control arm will receive no additional services or activities. In health districts containing randomized private facilities in the intervention arm, DKT will implement their activities.
The primary objective of this study is to estimate the impact of DKT's activities on modern contraceptive use. The secondary objectives are:

Behavioral: Social marketing activities
The intervention activities are designed to expand access to and create demand for family planning services among community members, especially women and girls. Activities include: * visiting pharmacies to encourage them to stock DKT-branded contraceptives * training public and private sector healthcare providers * partnering with existing private clinics to provide training and commodity support * organizing subsidised contraceptive access days for the community, where DKT provides contraceptives for free and the facilities charge a nominal fee to clients to generate revenue and gradually develop financial sustainability. * training qualified midwives to provide contraceptive services in remote communities * advertising contraceptives on billboards, radio, social media and other digital channels, and in pharmacies * advertising DKT's regional call center * organizing public events to raise awareness about family planning * community mobilization by community health workers.
Proportion of Women Using (or Whose Partner Uses) a Modern Contraceptive Method (mCPR)
Proportion of women aged 15-49 who use, or whose partners use, a modern contraceptive method. Modern methods include: female and male sterilization, oral contraceptive pills, IUDs, implants, injectables, male or female condoms, patch/ring, emergency contraception, Lactational Amenorrhea Method (LAM), fertility awareness based methods (FABM) such as standard days method and Billings ovulation method, and other supply methods (diaphram, foam/jelly). Aggregated as a proportion at each round; between-arm effect estimated via difference-in-differences.
Time frame: Baseline; Month 12 of intervention; Month 24 of intervention; Month 36 of intervention (Endline)
Proportion of Women Whose Contraceptive Use or Non-Use Is Concordant with Their Fertility Preferences (Preference-Aligned Fertility Management)
Proportion of women aged 15-49 classified as preference-concordant by the Preference-Aligned Fertility Management (PFM) indicator: using contraception and wanting to be, or not using and not wanting to be (adapted from the preference-aligned fertility management indicator developed by Holt and colleagues). A pre-specified sensitivity analysis classifies women reporting any pressure on their use or non-use as discordant.
Time frame: Baseline; Month 12 of intervention; Month 24 of intervention; Month 36 of intervention (Endline)
Unintended Pregnancy Incidence Rate
Proportion of women aged 15-49 who report a new pregnancy that was unwanted or mistimed since the previous round, based on pregnancy history and retrospective wantedness.
Time frame: Baseline; Month 12 of intervention; Month 24 of intervention; Month 36 of intervention (Endline)
Proportion of Women Who Report Making the Final Decision About Contraceptive Use Alone or Jointly With Their Partner
Proportion of women aged 15-49 who respond "you alone" or "you and your husband/partner jointly" to the question "Who would you say makes the final decision about you using contraception?" Respondents indicating that a husband/partner, parent/caregiver, a health care provider, another family member, or another person decides alone or jointly are classified as not having decision-making autonomy.
Time frame: Baseline; Month 12 of intervention; Month 24 of intervention; Month 36 of intervention (Endline)
Proportion of Women Reporting That Their Contraceptive Use or Non-Use Was Entirely Their Own Choice
Proportion of non-pregnant women aged 15-49 who respond "entirely my choice" to whether their current contraceptive status reflects their own choice, free from pressure. Current users are asked whether use of their current method was their choice ("that no one pressured you or strongly encouraged you to use this particular method"); non-users are asked whether not using is their choice ("that no one pressured you into not using"). The measure operationalizes freedom from pressure as a component of contraceptive autonomy (Senderowicz 2020)
Time frame: Baseline; Month 12 of intervention; Month 24 of intervention; Month 36 of intervention (Endline)
Mean Score on the Contraceptive Self-Efficacy Among Women in Sub-Saharan Africa (CSESSA) Scale
Mean score on the validated 10-item CSESSA for women aged 15-49. The score is calculated by summing all item values, creating a total score ranging from 0 to 100 across the partner-communication, provider-communication, and choosing/managing-a-method subscales.
Time frame: Baseline; Month 12 of intervention; Month 24 of intervention; Month 36 of intervention (Endline)
Proportion of Women With Unmet Need for Modern Contraception
Proportion of women aged 15-49 with an unmet need for modern contraception, following the revised DHS definition (Bradley et al. 2012). A woman has unmet need for modern contraception if she is fecund; exposed to the risk of pregnancy (i.e. currently married or in union (assumed exposed), or unmarried and sexually active in the past 30 days); wants to stop childbearing, delay the next birth by at least two years, or is undecided about timing - or is pregnant or postpartum amenorrheic following a mistimed or unwanted pregnancy - and is not using a modern contraceptive method.
Time frame: Baseline; Month 12 of intervention; Month 24 of intervention; Month 36 of intervention (Endline)
Proportion of Women With Supply-Side Unmet Need For Modern Methods of Contraception
Proportion of women who report supply-side unmet need for modern contraceptive methods. Supply-side unmet need classifies women with unmet need (revised DHS definition, any modern method, as above) who report at least one access-related reason for non-use, following Senderowicz and Maloney (Population and Development Review, 2022). Access-related reasons captured by the survey are: knows no method; knows no source; lack of access or distance; cost; preferred method not available; no method available. Women with unmet need who cite only demand-side reasons (e.g., opposition to use, side-effect or health concerns) constitute demand-side unmet need, the complement of supply-side unmet need among women with unmet need. A pre-specified sensitivity analysis instead restricts to women with unmet need who report wanting to use contraception (Senderowicz et al., Studies in Family Planning, 2023).
Time frame: Baseline; Month 12 of intervention; Month 24 of intervention; Month 36 of intervention (Endline)
12-Month Contraceptive Discontinuation Rate
The proportion of episodes of modern contraceptive method use discontinued within 12 months of initiation, estimated from the survey's month-by-month contraceptive calendar using single-decrement life-table methods, following DHS analytic conventions. We define the end of an episode at the first calendar month of non-use; a switch to another modern method in the same or immediately following month is treated as continued contraceptive use in the overall rate and as method-specific discontinuation in method-level rates. Overall and method-specific 12-month discontinuation rates will be reported, distinguishing discontinuation while still in need of contraception from discontinuation due to no need (e.g., seeking pregnancy). The calendar administered at each wave covers at least the preceding 12 months, so each assessment reflects use episodes observable in that window.
Time frame: Month 12 of intervention; Month 24 of intervention; Month 36 of intervention (Endline)
Proportion of Women Reporting Physical, Emotional, Sexual, or Economic Intimate Partner Violence (IPV)
Proportion of women aged 15-49 who report experiencing physical, emotional, sexual, or economic intimate partner violence in the past 12 months as assessed using the DHS domestic violence module
Time frame: Baseline; Month 12 of intervention; Month 24 of intervention; Month 36 of intervention (Endline)
Mean Score On 9-Item Women's Agency Measure
Mean score on a nine-item self-reported measure of general agency covering decision-making over daily life, voice, capacity to act on life choices, and freedom of movement. Items were adapted from established frameworks for measuring women's and adolescent girls' agency.

Administered to all women aged 15-49 at each survey wave.
Time frame: Baseline; Month 12 of intervention; Month 24 of intervention; Month 36 of intervention (Endline)
Mean Score on the Short 5-Item Reproductive Coercion Scale
Proportion of women aged 15-49 reporting any of the five reproductive-coercion behaviors on the validated 5-item short-form Reproductive Coercion Scale (or the mean item count) in the past 12 months. Coercive behaviors include: being told not to use contraception; having birth control taken away or being kept from obtaining it; being made to have unprotected sex in order to become pregnant; condom removal during sex; and deliberate condom damage. Items are adapted to ask about coercion by any person, not only an intimate partner.
Time frame: Baseline; Month 12 of intervention; Month 24 of intervention; Month 36 of intervention (Endline)
Proportion of Respondents' Children of Who Dropped Out of School
