Abstract
Globally, anxiety disorders affect an estimated 301 million people (WHO, 2021) and are among the top 10 causes of disability-adjusted life years (DALYs). In Africa, the prevalence of common mental disorders is estimated at 12–15%, with Rwanda experiencing higher rates in vulnerable groups such as genocide survivors, youth, and patients with HIV/AIDS. Early detection at the community level is therefore not only a health imperative but also a socio-economic and policy priority aligned with Rwanda’s Vision 2050.

Anxiety disorders are a leading cause of disability worldwide, and emerging evidence suggests a substantial burden in Rwanda across age groups. Early identification in primary-level community health centers (CHCs) is essential to reduce morbidity, improve functioning, and shorten duration of untreated illness. Rwanda has prioritized mental health within national policy frameworks and has piloted decentralised models of care (including task-shifting and mentorship programs). However, persistent barriers — stigma, limited human resources, variable provider skills, lack of routine screening, and scarce context-validated screening tools — impede systematic early detection of anxiety at the community level. This paper synthesizes current evidence on prevalence and correlates of anxiety in Rwanda, evaluates screening tools and their validation in Kinyarwanda, reviews implementation experiences (including mhGAP-informed primary care integration and the MESH-MH mentorship model), and identifies operational, cultural, and health-systems challenges. We propose pragmatic, evidence-informed opportunities for improving early detection in CHCs: (1) adopt brief validated screening (e.g., Kinyarwanda GAD-7, adapted cut-offs) embedded into routine visits; (2) scale up task-sharing with nurses, community health workers (CHWs), and lay counsellors supported by structured supervision and digital decision aids; (3) integrate screening with other vertical programs (maternal health, NCD clinics) to leverage patient contacts; (4) strengthen referral pathways and supply of first-line psychosocial interventions; (5) conduct implementation research to determine cost-effectiveness and local acceptability. We conclude with a targeted research and policy agenda for Rwanda to convert existing momentum into sustainable, equitable early-detection systems for anxiety disorders at the community health level.

1. Introduction

Anxiety disorders cause substantial distress, reduced productivity, and increased physical comorbidity. In LMICs, detection and treatment gaps are large. Rwanda has made notable investments in mental health since the 1994 genocide but challenges remain in expanding access to early identification and treatment at the community level.

Global experiences in screening for anxiety disorders reveal that early detection in primary health care can reduce disease burden, improve treatment adherence, and prevent chronicity. In high-income countries, tools like GAD-7 and PHQ-9 are routinely integrated into primary care. In LMICs, integration is limited but promising evidence from Uganda, Kenya, and Ethiopia suggests feasibility with task-sharing models. In Rwanda, the legacy of the 1994 genocide continues to shape mental health trajectories, with higher-than-average prevalence rates of anxiety and PTSD compared to regional averages.

2. Methods (scope and approach)

This is a narrative, policy-oriented review structured to inform implementation in Rwandan CHCs. Sources include peer-reviewed studies on mental health prevalence and service delivery, national policy documents, and validation/adaptation studies for screening tools (PHQ-9, GAD-7) in Kinyarwanda.

3. Epidemiology and burden in Rwanda

Recent studies indicate a notable burden of common mental disorders including anxiety, with prevalence estimates ranging from 13–20%. High-prevalence groups include students, people with chronic NCDs, and survivors of trauma.

4. Existing policy and service-delivery frameworks

Rwanda’s National Mental Health Policy emphasizes decentralisation, integration of mental health into primary care, workforce development, and community engagement. Implementation gaps remain, particularly in human resources and routine screening.

5. Screening tools: validity, feasibility, and cultural adaptation

Brief screening instruments used globally include GAD-7, K6/K10, and mhGAP checklists. Kinyarwanda versions of GAD-7 and PHQ-9 show reliability but need further validation. Local adaptation is critical to ensure accuracy.

6. Implementation experiences and models in Rwanda

The MESH-MH approach and mhGAP-informed programs have improved provider skills and outcomes. Challenges include sustained supervision, supply-chain issues for medications, and limited access to psychosocial interventions.

7. Barriers to screening and early detection in CH

Key barriers include stigma, limited human resources, lack of training, inadequate referral systems, and weak integration into HMIS.

1. **Financing gaps:** Rwanda’s national budget allocates less than 1% to mental health, limiting scaling of screening.
2. **Cultural factors:** Anxiety symptoms are often described using idioms like ‘umutima urahagaze’ (the heart has stopped), which may not align with biomedical constructs.
3. **Health information systems:** HMIS does not systematically capture anxiety screening data.
4. **Training gaps:** Nurses and CHWs report low confidence in applying screening tools, especially for youth.

8. Opportunities and practical recommendations

Recommendations include adopting stepped screening algorithms, integrating into high-yield services, scaling task-sharing, strengthening referral pathways, using digital tools, engaging communities, and investing in implementation research.

9. Monitoring and evaluation framework (practical metrics)

Indicators include screening coverage, positive screen rates, referrals, treatment initiation, outcomes, and implementation fidelity.

10. Research gaps and priorities

Gaps include local cut-off validation, screening trials, cost-effectiveness analyses, task-sharing outcomes, and digital tool pilots.

11. Discussion

Rwanda has strong policy support and pilot programs, but scaling requires addressing supervision, stigma, financing, and data systems. Screening must be paired with treatment availability.

12. Limitations

This is a narrative review; not all studies were captured. Prevalence estimates vary by method and context.

13. Conclusions

Screening and early detection of anxiety disorders in CHCs is feasible and aligned with policy. Brief tools, task-sharing, supervision, and community engagement are essential.

14. Recommendations

1. Ministry of Health: adopt national guidance for a two-step screening algorithm. 2. District health teams: pilot integration into ANC and chronic disease clinics. 3. CHC managers: train staff and protect screening time. 4. Researchers: run pragmatic implementation trials. 5. Donors and partners: fund psychosocial interventions and digital tools.
