Can a combination of interventions accelerate outcomes to deliver on the Sustainable Development Goals for young children? Evidence from a longitudinal study in South Africa and Malawi

Whole of government approaches to accelerate adolescent success: efficiency and financing considerations

The multiple domains of development covered by the Sustainable Development Goals (SDGs) present a practical challenge for governments. This is particularly acute in highly resource-constrained settings which use a sector-by-sector approach to structure financing and prioritization. One potentially under-prioritized solution is to implement interventions with the potential to simultaneously improve multiple outcomes across sectors, what United Nations Development Programme refer to as development 'accelerators'. An increasing number of accelerators are being identified in the literature. There are, however, challenges associated with the evaluation and implementation of accelerators. First, as accelerators have multiple benefits, possibly in different sectors, they will be undervalued if the priority setting is conducted sector-by-sector. Second, even if their value is recognized, accelerators may not be adopted if doing so clashes with any of the multiple competing interests policymakers consider, of which efficiency/social desirability is but one. To illustrate the first challenge, and outline a possible solution, we conduct a cost-effectiveness analysis comparing the implementation of three sector-specific interventions to an accelerator, first using a sector-by-sector planning perspective, then a whole of government approach. The case study demonstrates how evaluating the cost-effectiveness of interventions sector-by-sector can lead to suboptimal efficiency rankings and overlook interventions that are efficient from a whole of government perspective. We then examine why recommendations based on a whole of government approach to evaluation are unlikely to be heeded. To overcome this second challenge, we outline a menu of existing and novel financing mechanisms that aim to address the mismatch between political incentives and logistical constraints in the priority setting and the economic evaluation evidence for cost-effective accelerators. These approaches to financing accelerators have the potential to improve efficiency, and in doing so, progress towards the SDGs, by aligning political incentives more closely with recommendations based on efficiency rankings.

Effect of multi-level interventions on mental health outcomes among adolescents in sub-Saharan Africa: a systematic review

OBJECTIVE

In sub-Saharan Africa (SSA), multiple factors contribute to the considerable burden of mental health disorders among adolescents, highlighting the need for interventions that address underlying risks at multiple levels. We reviewed evidence of the effectiveness of community or family-level interventions, with and without individual level interventions, on mental health disorders among adolescents in SSA.

DESIGN

Systematic review using the Grades of Recommendation, Assessment, Development and Evaluation approach.

DATA SOURCES

A systematic search was conducted on Cochrane Library, MEDLINE, EMBASE, PSYCINFO and Web of Science up to 31 March 2021.

ELIGIBILITY CRITERIA

Studies were eligible for inclusion in the review if they were randomised controlled trials (RCTs) or controlled quasi-experimental studies conducted in sub-Saharan African countries and measured the effect of an intervention on common mental disorders in adolescents aged 10-24 years.

DATA EXTRACTION AND SYNTHESIS

We included studies that assessed the effect of interventions on depression, anxiety, post-traumatic stress disorder and substance abuse. Substance abuse was only considered if it was measured alongside mental health disorders. The findings were summarised using synthesis without meta-analysis, where studies were grouped according to the type of intervention (multi-level, community-level) and participants.

RESULTS

Of 1197 studies that were identified, 30 studies (17 RCTs and 3 quasi-experimental studies) were included in the review of which 10 delivered multi-level interventions and 20 delivered community-level interventions. Synthesised findings suggest that multi-level interventions comprise economic empowerment, peer-support, cognitive behavioural therapy were effective in improving mental health among vulnerable adolescents. Majority of studies that delivered interventions to community groups reported significant positive changes in mental health outcomes.

CONCLUSIONS

The evidence from this review suggests that multi-level interventions can reduce mental health disorders in adolescents. Further research is needed to understand the reliability and sustainability of these promising interventions in different African contexts.

Accelerating ontological security for South African adolescents living in high HIV-prevalence areas: a longitudinal study

Ontological security is the personal need to build fundamental certainty about the continuity of life events. It is central to long-term human development, particularly among adolescents in highly vulnerable communities in South Africa. We examined the cumulative effects of eight hypothesised provisions (development accelerators) in reducing the risks of ontological insecurity outcomes aligned with Sustainable Development Goals (SDGs) targets. Three waves of survey data from adolescents living in high HIV prevalence areas in South Africa were analysed. We used standardised tools to measure twelve outcomes linked to two dimensions of ontological security: mental health and violence. Sustained receipt (at baseline and follow-ups) of eight hypothesised accelerators were examined: emotional and social support, parental/caregiver monitoring, food sufficiency, accessible health care, government cash transfers to households, basic economic security, positive parenting/caregiving, and participation in extramural activities. Associations of all accelerators with outcomes were evaluated using multivariable regressions controlling for age, sex, orphanhood and HIV status, rural/urban location, and informal housing. Cumulative effects were tested using marginal effects modelling. Of 1,519 adolescents interviewed at baseline, 1,353 (89%) completed the interviews at two follow-ups. Mean age was 13.8 at baseline; 56.6% were female. Four provisions were associated with reductions in twelve outcomes. Combinations of accelerators resulted in a percentage reduction risk in individual indicators up to 18.3%. Emotional and social support, parental/caregiver monitoring, food sufficiency and accessible health care by themselves and in combination showed cumulative reductions across twelve outcomes. These results deepen an essential understanding of the long-term effects of consistent exposure to accelerators on multi-dimensional human development. They could be directly implemented by existing evidence-based interventions such as peer-based psychosocial support, parenting programmes, adolescent-responsive healthcare and food support, providing safer and healthier environments for South African adolescents to thrive.

Predictors of COVID-related changes in mental health in a South African sample of adolescents and young adults

The COVID-19 pandemic has substantially affected the lives of young people living in sub-Saharan Africa (SSA), leading to poorer short-term mental health outcomes. However, longitudinal data investigating changes in mental health from pre-COVID levels and their predictors are lacking. Our longitudinal sample comprised N = 233 young people (mean age: 17.8 years at baseline, 55.6% female) living in a deprived neighbourhood near Cape Town, South Africa. Symptoms of depression (PHQ-9), anxiety (GAD-7) and alcohol use (AUDIT) were assessed during two waves of data collection, pre-pandemic (2018/19) and via phone interviews in June to October 2020, during South Africa's first COVID wave and subsequent case decline. Latent change score models were used to investigate predictors of changes in mental health. Controlling for baseline levels, we found increases in depression and anxiety but not alcohol use symptoms during the COVID-19 pandemic. Higher baseline symptoms were associated with smaller increases on all measures. Socio-economic deprivation (lack of household income, food insecurity) before and during COVID were associated with higher anxiety and depression symptom increases. Having had more positive experiences during COVID was associated with lower post-COVID onset anxiety and depression increases, and marginally with less alcohol use, while negative experiences (household arguments, worries) were linked to stronger symptom increases. Overall, in a sample of young people from an adverse environment in South Africa, we found increased mental health difficulties during the COVID-19 pandemic, though higher baseline symptoms did not necessarily predict stronger increases. Several factors pre- and post-COVID onset were identified that could be relevant for determining risk and resilience. In the long term, it will be key to address these structural drivers of well-being and to ensure mental health needs of young people are being met to support SSA countries in building back successfully from COVID-19 and preparing for future shock events.
