Our Recommendation
Shamiri is a research‑driven mental health organization with multiple randomized controlled trials showing meaningful reductions in adolescent depression and anxiety and improvements in wellbeing and academics at relatively low cost. For funders focused on youth mental health in low‑resource settings, Shamiri is a compelling candidate—especially as a “learning bet” that already has strong counterfactual evidence and a clear path to further increasing cost‑effectiveness and scale.
Shamiri Institute's Fierce Certification score is 120/100 based on our criteria:
✔ Has Ultimate Outcome Goals (50 pts)
✔ Measures Intermediate Outcomes (10 pts)
✔ Measures Ultimate Outcomes (15 pts)
✔ Shows Continual Learning & Adaptation (25 pts)
✔ Measures Intermediate Counterfactual (10 pts)
✔ Measures Ultimate Counterfactual (10 pts)
The Social Problem
Shamiri tackles untreated adolescent mental distress in low‑resource school settings, initially in Kenya. With very few mental‑health professionals available and high stigma, large numbers of adolescents experience clinically elevated depression and anxiety without help, harming their wellbeing, academic prospects, and long‑term life outcomes. This gap also contributes to wider social and economic costs, including lower productivity and a barrier to realizing the demographic potential of a very young population.
The Solution
Shamiri’s core solution is a brief, group‑based intervention delivered in schools by trained lay providers (recent high‑school graduates) rather than clinicians. Over four sessions, adolescents learn about growth mindset, gratitude, and values alignment, with content tailored to be low‑stigma and strengths‑focused rather than pathology‑focused. The organization layers this with a three‑tiered caregiving model (school‑based groups, higher‑intensity support for those who need it, and referral pathways) and supports scaling through shamiriOS, a digital platform for real‑time monitoring and fidelity.
Key Outputs
Key outputs include:
- Youth reached: more than 130,000 youth served since 2018 and over 100,000 adolescents reached in the most recent year alone; more recent figures from the impact page indicate 285,000+ youth reached cumulatively.
- Program footprint: work across dozens of Kenyan schools and expansion to new geographies through dissemination trials.
- Research portfolio: at least a dozen RCTs and experimental studies testing the Shamiri intervention and its components, along with a growing program of long‑term follow‑up and implementation research.
- Digital infrastructure: development of shamiriOS to provide partners with data visualization and live monitoring of interventions.
These outputs reflect both direct service delivery and a substantial contribution to global evidence on youth mental health interventions in low‑resource contexts.
Key Intermediate Outcomes
Intermediate outcomes where Shamiri has strong evidence:
- Improved psychosocial functioning: RCTs show that participants experience greater improvements than controls in social support from friends, perceived control, gratitude, and related wellbeing dimensions.
- Reduced loneliness and better relationships: trials report reduced loneliness and higher perceived peer support compared to an active study‑skills control, indicating improved social connectedness.
- Positive affect and engagement: use of the EPOCH wellbeing scale shows gains in engagement, optimism, connectedness, and happiness among Shamiri participants relative to controls.
All of these outcomes are derived from randomized controlled trials, providing strong counterfactual evidence on the mechanisms linking the intervention to better mental health.
Key Ultimate Outcomes
Shamiri’s core ultimate outcomes include:
- Reduced depression and anxiety: multiple RCTs demonstrate significant reductions in depressive and anxiety symptoms, with effect sizes around d ≈ 0.30 compared to active controls, and benefits lasting up to seven months after the intervention.
- Improved academic performance: trial results show improvements in academic outcomes (e.g., exam scores) for participants versus controls, suggesting benefits spill over into educational attainment.
- Overall wellbeing (WELLBYs): the Happier Lives Institute’s 2026 evaluation estimates that Shamiri delivers 3–5 times the wellbeing impact of GiveDirectly cash transfers, using WELLBYs to compare to a no‑program counterfactual.
A long‑term follow‑up protocol is tracking whether these gains translate into sustained mental‑health and socio‑economic improvements 3–4 years post‑intervention.
Continual Learning & Adaptation
Shamiri is clearly a learning organization:
- It has run iterative RCTs on different elements of its model (e.g., testing each of growth mindset, gratitude, and values components separately) to refine its theory of change.
- It is now conducting long‑term follow‑up of past RCT participants and a socioeconomic impact study to understand how short‑term mental‑health gains translate into later life outcomes.
- It invests in implementation research and digital infrastructure (shamiriOS and dissemination trials) to understand how best to scale with quality, and external evaluators explicitly note its “strong research culture, dedication to cost‑effectiveness, and willingness to experiment.”
Altogether, Shamiri aligns closely with our four‑step cycle: explicit theory of change, disciplined implementation, rigorous counterfactual measurement at both intermediate and ultimate outcome levels, and active feedback of learning into program design and scaling strategy.
