In low- and middle-income countries (LMICs), approximately twenty percent of women who bear children experience depression during pregnancy or in the year after their child’s birthday, called perinatal depression, but they are rarely diagnosed or treated. Researchers evaluated the impact of a cognitive behavioral therapy (CBT) program on the mental health, financial empowerment, and parenting decisions of 903 women with perinatal depression in Pakistan. They found that the CBT program reduced postpartum depression. The program also had long-term outcomes: seven years later, a different team of researchers found a reduction in depression rates, an improvement in financial empowerment, and an increase in time- and money-related parental investments, particularly for mothers of girls.

Researchers conducted a randomized evaluation to test the impact of offering frequent HIV testing on rates of marriage and pregnancy. Offering high-frequency, opt-out HIV testing to young women and their partners changed beliefs of partner’s sexual safety, accelerated marriage, and increased the probability of pregnancy.

Researchers introduced text message reminders to evaluate their effect on Kenyan patients taking their antiretrovirals consistently and not skipping doses. Patients who received weekly text messages were more likely to take their medicine 90 percent of the time and were less likely to skip doses for more than 48 hours than their counterparts in the comparison group.

Training teachers to improve teacher quality and student learning is a common strategy taken by policymakers. In Nepal, researchers conducted a randomized evaluation of a government teacher training program for math and science teachers to evaluate the impact on student learning in secondary schools.

Despite making great strides in expanding access to education, developing countries like India continue to lag in measures of actual student learning. To understand how quality of education mediates learning, this randomized control trial evaluates a pedagogical intervention training science teachers in rural Uttar Pradesh, India. The curiosity-based curriculum emphasizes practical techniques along with foundational principles on effective answer-seeking, guided research, constructive feedback, and peer-to-peer communication. The researchers assess whether active teaching approaches increase student recall of course material, curiosity, student engagement, critical thinking, and other soft skills foundational to developing students’ intrinsic motivation to learn.

Researchers conducted a randomized evaluation to test the impact of providing information to students on their decision to pursue courses and majors in economics at a public university in the United States. The intervention increased male students' likelihood of studying additional economics courses when compared to female students, but the intervention did not impact students’ decision to major in economics, irrespective of gender.

Researchers evaluated the impact of exposure to and incentives to consume discordant media on political attitudes and behaviors in Turkey. Participants changed their media consumption habits, trusted discordant media sources more, and had less polarized attitudes towards the government, but did not change how much they trusted people with opposing political views.

Researchers conducted a randomized evaluation to test the impact of an entertainment-education short film informational campaign (i.e. edutainment campaign) designed to inform adolescent girls and parents of the costs of child marriage on the norms and perceptions about child marriage in Indonesia. The edutainment intervention was effective in changing the perceptions of girls and parents towards child marriage.

Researchers investigated the role of online networking groups (via WhatsApp) and free legal aid on improving business innovation, practices, sales, and profits among growth-oriented women-owned firms in Ghana. They found that online networking groups meaningfully encouraged business innovation, improved participants’ business practices, and boosted firm profits.

Researchers conducted a randomized evaluation to test the impact of two different performance-based incentives on students’ test scores, motivation, and behavior in Malawi. They find that tournament-style incentives that rewarded the top performers among a large group lowered test scores and student motivation, especially among lower-performing students, while tournaments among small groups based on initial performance did not impact students’ test scores.

Researchers conducted an evaluation to test the impact of offering a high-amenity diagnostic consultation for cataracts at different prices on uptake of an underutilized service—cataract surgery—in Mexico. Lower prices for the high-amenity consultation increased exposure to amenities, which ultimately boosted surgery take-up.

Researchers conducted a randomized evaluation to test the impact of providing information about police alternatives on individuals' reported likelihood of calling the police and a follow-up randomized evaluation to understand key public-safety stakeholders’ receptiveness of police alternatives. The first study found that information about police alternatives had a bipartisan decrease on police reliance in nonviolent scenarios. The second study revealed that police are more responsive to evidence on public interest in police alternatives when it is presented using some framing devices compared to others.

Researchers conducted a randomized evaluation to test the impact of a video-mediated extension approach on the uptake of technologies recommended by the Ethiopian Ministry of Agriculture. The video-mediated instruction increased uptake through improved access to extension and farmer knowledge but did not improve crop yields. Targeting spouses in addition to heads of households with the video approach increased spouses access to extension services and knowledge of the recommended technologies but it did not further increase technology adoption.

Researchers conducted a randomized evaluation to test the impact of an edutainment intervention at schools and the provision of handwashing resources at home on handwashing at school and at home. These findings suggest that encouraging behavior change in one setting may crowd out like behavior in another setting.

Researchers conducted a randomized evaluation to test how encouraging traditional leaders to broaden their circle of advisors affects inclusive governance in Zimbabwe. Village chiefs improved their decision-making processes when they attended the workshop on inclusive and transparent governance and were accompanied by a civil society member.
