The burden of mental disorder in Sierra Leone: a retrospective observational evaluation of programmatic data from the roll out of decentralised nurse-led mental health units

Advancing sustainable implementation of an evidence-based mental health intervention in Sierra Leone's schools: protocol for a hybrid type 3 implementation-effectiveness trial

BACKGROUND

Mental health disorders among youth contribute substantially to the global burden of disease, which is exacerbated in low- and middle-income countries (LMICs) due to large mental health treatment gaps. In Sierra Leone, a West African country with a long history of complex adversity, the mental health treatment gap is estimated at 98%. Implementing innovative mental health interventions that can be sustained at scale is a priority. The Youth Readiness Intervention (YRI) is an evidence-based mental health intervention for youth that can be delivered feasibly by lay health workers/nonspecialists. Using mobile-based technologies to assist implementation could improve the reach and sustainability of the YRI in Sierra Leone. This study aims to train teachers to deliver the YRI in Sierra Leone's secondary schools and test the feasibility, acceptability, cost, and fidelity to the YRI of a mobile-based supervision model compared with standard, in-person supervision.

METHODS

We will conduct a hybrid type 3 implementation-effectiveness cluster randomized trial to assess the feasibility, acceptability, costs and fidelity to the YRI implemented by teachers receiving mobile-based supervision vs. standard supervision. Enrolled schools (N = 50) will be randomized to YRI + mobile supervision (N = 20), YRI + standard supervision (N = 20) or waitlist control (N = 10). We will recruit and enroll four teachers per intervention-condition school (N = 160) and 1200 youth. We will collect data on implementation outcomes among teachers, principals and youth via a mixed methods approach at baseline and post-intervention. We will also collect quantitative data on youth mental health and functioning as secondary outcomes at baseline and post-intervention, as well as cost-effectiveness data at 12-month follow-up.

DISCUSSION

Study findings have the potential to expand the reach of mental health services among youth in low-resource settings via a teacher workforce. The use of mobile tools, if successful, could support further scale out and sustainment of the YRI to other regions of Sierra Leone and West Africa more broadly, which could help address the mental health treatment gap.

The Barriers and Facilitators to Decentralised Nurse-Led Mental Health Service Delivery in Sierra Leone

In 2009, 98.0% of people with mental illness in Sierra Leone were not receiving treatment, partly due to the absence of public psychiatric facilities outside the capital. In response to this situation, the Ministry of Health and Sanitation rolled out nurse-led mental health units (MHUs) to every district. This study evaluates the barriers and facilitators to mental health service delivery in decentralised MHUs in Sierra Leone using key informant interviews and focus group discussions with 13 purposefully sampled clinical staff and senior management personnel. The interviews were audio-recorded, translated from Krio if necessary, transcribed, and analysed using manifest content analysis. The findings suggest that factors affecting nurse-led mental health service delivery include small workforce and high workload, culture and beliefs, risks, lack of safety measures and required resources, outdated policies, poor salaries, lack of funds for medication, distance, power, influence, and stigma. Factors that could facilitate nurse-led mental health services include: increasing motivation, increasing the workforce, knowledge sharing, mentorship, availability of medication, passion and modern psychiatry. The findings contribute towards understanding the challenges and opportunities faced by the recently established nurse-led decentralised mental health services across Sierra Leone, in order to address the large mental health treatment gap. We hope the findings will inform further policy and planning to improve the quality of decentralised mental healthcare.

Exploring potential mental health spillover effects among caregivers and partners of youth in Sierra Leone: A qualitative study

Given the large mental health treatment gap in low- and middle-income countries (LMICs), particularly in post-conflict settings like Sierra Leone, and the limited healthcare infrastructure, understanding the wider benefits of evidence-based mental health interventions within households is critical. This study explored potential mental health spillover effects - the phenomenon of beneficial effects among nonparticipants - among cohabitating caregivers and partners of youth who participated in an evidence-based mental health intervention in Sierra Leone. We recruited a sub-sample of cohabitating caregivers and partners (N = 20) of youth intervention participants; caregivers had enrolled in a larger study investigating indirect benefits of the evidence-based intervention in Sierra Leone (MH117359). Qualitative interviews were conducted at two time points to explore the following: (a) potential mental health spillover effects and (b) through which mechanisms spillover may have occurred. Two trained coders reviewed transcripts and analyzed qualitative data, assisted by MaxQDA. Qualitative findings suggested that spillover effects likely occurred and supported three potential mechanisms: decreased caregiving burden, behavior changes among Youth Readiness Intervention participants and improved interpersonal relationships. Mental health spillover effects may occur following youth intervention participation in a post-conflict LMIC. Investing in evidence-based services may offer indirect benefits that extend beyond those directly receiving services.

Exploring Naturalistic Diffusion of an Evidence-Based Mental Health Intervention across Peer Networks of Youth in Sierra Leone

BACKGROUND

Understanding the mechanisms by which evidence-based interventions (EBIs) for mental health are naturally diffused among youth in low-and middle-income countries-particularly those with histories of violence and civil unrest-can illuminate which intervention elements are most transferrable and inform scale-up decisions that support youth adjustment. This study explored the diffusion of an evidence-based mental health intervention-the Youth Readiness Intervention (YRI)-among peer networks of Sierra Leonean youth (aged 18-30) who participated in a trial of the intervention as integrated into youth entrepreneurship programs.

METHODS

Trained research assistants recruited index participants who had completed the YRI integrated within entrepreneurship training (N = 165) and control index participants (N = 165). Index participants nominated three of their closest peers. Nominated peers were recruited and enrolled in the current study (N = 289). A sub-sample of index participants and peers participated in dyadic interviews (N = 11) and focus group discussions (N = 16). Multivariate regression analysis compared YRI knowledge levels among YRI participants' peers relative to control participants' peers.

RESULTS

Qualitative findings supported the diffusion of several YRI skills and components across peer networks (i.e., progressive muscle relaxation and diaphragmatic breathing). Quantitative findings indicated that YRI knowledge was significantly higher for YRI participants' peers (β = 0.02, p < 0.00) compared to control participants' peers.

CONCLUSION

Findings suggest that diffusion of evidence-based intervention components can occur naturally among peers in post-conflict LMIC settings. Developing tools to promote the diffusion of the most transferrable EBI components across peer networks could help maximize the benefits of mental health interventions for youth adjustment and resilience in post-conflict settings.

Sexual risk behaviour among school-going adolescents in Sierra Leone and Liberia: a secondary analysis of the 2017 Global school-based student health surveys

BACKGROUND

Sierra Leone and Liberia have experienced civil wars and, recently, Ebola outbreaks that led to profound economic hardship, psychopathologies and family disruptions. These factors are associated with sexual risk behaviours among youths. However, there is very little information on sexual risk behaviour among Sierra Leonean and Liberian school-going adolescents. The present study assessed the prevalence and determinants of sexual risk behaviours among school-going adolescents (10-19 years) in Sierra Leone and Liberia.  METHOD: We used publicly available nationally representative cross-sectional datasets of the 2017 Sierra Leone and Liberia Global school health survey. The sample consisted of 2798 and 2744 school-going adolescents from Sierra Leone and Liberia, respectively. Complex sample descriptive and regression analysis was used to analyse our data.

RESULTS

The majority of adolescents in the two countries were involved in multiple sexual risk behaviour (80.2%), with a higher prevalence observed in Sierra Leone (85.2%) than in Liberia (75.3%). Liberian adolescents showed lesser odds of indulging in multiple sexual risk behaviours than their Sierra Leonean counterparts (AOR = 0.572; 95%CI: 0.345-0.946). Male, compared to females, were more likely to engage in multiple sexual risk behaviour (AOR = 2.310;95%CI:1.543-3.458), with a similar pattern observed in both countries. Alcohol use was associated with multiple sexual risk behaviour (AOR = 3.064; 95%CI: 2.137-4.392). Also, in Sierra Leone and Liberia, adolescents with one and two or more forms of psychological distress were more likely to have ever had sex than those who did not show any form of psychological distress. Missing class/school was associated with multiple sexual risk behaviour (AOR = 1.655; 95%CI:1.133-2.418). Peer support was only found to be a protective factor against no condom use among Liberian adolescents (AOR = 0.608; 95%CI: 0.435-0.850). Less parental support was only associated with ever had sex among adolescents in Sierra Leone (AOR = 2.027; 95%CI: 1.322-3.107) but not in Liberia (AOR = 1.034; 95%CI: 0.650-1.644).

CONCLUSION

Our study found a high sexual risk behaviour among school-going adolescents in Sierra Leone and Liberia. Our finding highlights the need to strengthen sexual and reproductive health education in schools and communities that incorporate mental health promotion activities tailored to this group.

An analysis of age-standardized suicide rates in Muslim-majority countries in 2000-2019

BACKGROUND

This study examines the 20-year trend of suicide in 46 Muslim-majority countries throughout the world and compares their suicide rates and trends with the global average. Ecological-level associations between the proportion of the Muslim population, the age-standardized suicide rates, male-to-female suicide rate ratio, and the Human Development Index (HDI) in 2019 were examined.

METHODS

Age-standardized suicide rates were extracted from the WHO Global Health Estimates database for the period between 2000 and 2019. The rates in each country were compared with the age-standardized global average during the past 20 years. The countries were further grouped according to their regions/sub-regions to calculate the regional and sub-regional weighted age-standardized suicide rates involving Muslim-majority countries. Correlation analyses were conducted between the proportion of Muslims, age-standardized suicide rate, male: female suicide rate ratio, and the HDI in all countries. Joinpoint regression was used to analyze the age-standardized suicide rates in 2000-2019.

RESULTS

The 46 countries retained for analysis included an estimated 1.39 billion Muslims from a total worldwide Muslim population of 1.57 billion. Of these countries, eleven (23.9%) had an age-standardized suicide rate above the global average in 2019. In terms of regional/sub-regional suicide rates, Muslim-majority countries in the Sub-Saharan region recorded the highest weighted average age-standardized suicide rate of 10.02/100,000 population, and Southeastern Asia recorded the lowest rate (2.58/100,000 population). There were significant correlations between the Muslim population proportion and male-to-female rate ratios (r=-0.324, p=0.028), HDI index and age-standardized suicide rates (r=-0.506, p<0.001), and HDI index and male-to-female rate ratios (r=0.503, p<0.001) in 2019. Joinpoint analysis revealed that seven Muslim-majority countries (15.2%) recorded an increase in the average annual percentage change regarding age-standardized suicide rates during 2000-2019.

CONCLUSIONS

Most Muslim-majority countries had lower age-standardized suicide rates than the global average, which might reflect religious belief and practice or due to Muslim laws in their judicial and social structure which may lead to underreporting. This finding needs further in-depth country and region-specific study with regard to its implication for public policy.
