Background: Making the case for investing in public health by illustrating the social, economic and environmental value of public health interventions is imperative. Economic methodologies to help capture the social value of public health interventions such as Social Return on Investment (SROI) and Social Cost-Benefit Analysis (SCBA) have been developed over past decades. The life course approach in public health reinforces the importance of investment to ensure a good start in life to safeguarding a safe, healthy and active older age. This novel review maps an overview of the application of SROI and SCBA in the existing literature to identify the social value of public health interventions at individual stages of the life course. Methods: A systematic scoping review was conducted on peer-reviewed and grey literature to identify SROI and SCBA studies of public health interventions published between January 1996 and June 2019. All primary research articles published in the English language from high-income countries that presented SROI and SCBA outputs were included. Studies were mapped into stages of the life course, and data on the characteristics of the studies were extracted to help understand the application of social value methodology to assess the value of public health interventions. Results: Overall 40 SROI studies were included in the final data extraction, of which 37 were published in the grey literature. No SCBA studies were identified in the search. Evidence was detected at each stage of the life course which included; the birth, neonatal period, postnatal period and infancy (n = 2); childhood and adolescence (n = 17); adulthood (main employment and reproductive years) (n = 8); and older adulthood (n = 6). In addition, 7 studies were identified as cross-cutting across the life course in their aims. Conclusion: This review contributes to the growing evidence base that demonstrates the use of social value methodologies within the field of public health. By mapping evidence across stages of the life course, this study can be used as a starting point by public health professionals and institutions to take forward current thinking about moving away from traditional economic measures, to capturing social value when investing in interventions across the life course.

BackgroundThere is a growing recognition of the need to effectively assess the social value of public health interventions through a wider, comprehensive approach, capturing their social, economic and environmental benefits, outcomes and impacts. Social Return on Investment (SROI) is a methodological approach which incorporates all three aspects for evaluating interventions. Mental health problems are one of the leading causes of ill health and disability worldwide. This study aims to map existing evidence on the social value of mental health interventions that uses the SROI methodology.MethodsA scoping evidence search was conducted on Medline, PubMed, Google Scholar and relevant gray literature, published in English between January 2000 and March 2021 to identify studies which capture the SROI of mental health interventions in high- and middle-income countries. Studies that reported mental health outcomes and an SROI ratio were included in this review. The quality of included studies was assessed using Krlev's 12-item quality assessment framework.ResultsThe search identified a total of 435 records; and 42 of them with varying quality met the study inclusion criteria. Most of the included studies (93%) were non-peer reviewed publicly available reports, predominantly conducted in the United Kingdom (88%); and majority (60%) of those studies were funded by charity/non-for-profit organizations. Out of 42 included studies, 22 were targeted toward individuals experiencing mental health problems and the remainder 20 were targeted to vulnerable groups or the general population to prevent, or reduce the risk of poor mental health. Eighty-one percent of included studies were graded as high quality studies based on Krlev's 12-item quality assessment framework. The reported SROI ratios of the included studies ranged from £0.79 to £28.00 for every pound invested.ConclusionThis scoping review is a first of its kind to focus on SROI of mental health interventions, finding a good number of SROI studies that show a positive return on investment of the identified interventions. This review illustrates that SROI could be a useful tool and source of evidence to help inform policy and funding decisions for investment in mental health and wellbeing, as it accounts for the wider social, economic and environmental benefits of public health interventions. More SROI research in the area of public health is needed to expand the evidence base and develop further the methodology.

Background Health literacy (HL) allows people to make informed decisions regarding their health, enabling them to understand health promotion activities and to self-manage their disease or complication without requiring support from healthcare services. HL has the potential to support sustainability in health systems by decreasing healthcare spendings stemming from lowered disease occurrence and progression, it can also impact on the rest of peoples’ lives and their surroundings by allowing them to be more independent. This study researched the evidence for return on investment and the social return on investment for health literacy interventions within the WHO EURO region. Methods A narrative literature review on published peer-reviewed reviews and grey literature was conducted by use of keywords and MeSH terms. Google, Google Scholar and PubMed were used find literature. The search on PubMed was restricted to reviews, published within the last 10 years (2009-2019), in English. Results In total, 450 publications were screened 12 publications that analysed the economic or social aspect of HL interventions were identified. Five discussed the cost-effectiveness of health literacy, three the return on investment (ROI) and the remaining three the social return on investment (SROI) of HL. Types of HL interventions ranged from health promotion campaigns, web-based HL programs, prevention systems to education-based interventions. Cost-effectiveness differed between studies and fields. Evidence for ROI was found, the return ratios ranged from 0.62 to 27.4. Findings show SROI between 4.41 and 7.25, indicating additional value of social benefit next to improved health. Conclusions A link between cost-effectiveness and HL interventions was established and ROI and SROI showed positive ratios. Further research is required in order to investigate whether HL interventions consistently achieve a positive returns. Key messages A link between health literacy interventions and positive investment returns has been established. Health literacy interventions show potential for sustainable development of health systems.

Background There is increasing recognition that Public Health Institutes need to build on the traditional value for money approach, to find ways to capture, measure and show the full range of their outcomes, impacts and related value. As part of a drive to measure value and impact in public health and demonstrate how investment in health can contribute to an Economy of Well-being, Public Health Wales has developed an interactive database to capture and illustrate the social value of public health services and interventions. Methods Scoping reviews of both academic and grey literature were undertaken to populate a database of health economics evaluations of public health interventions, focusing on Social Return on Investment (SROI). In addition, a simulated methodology was developed which allows the evidence to be manipulated and made relevant to individual contexts to help inform investment decisions at a local level. Results To date, the database has accumulated an excess of 50 SROI evaluations of various public health interventions, across areas including mental health, behaviour change, physical activity, nutrition, employment and primary care. The evaluations are based on European and International contexts, are published in both grey and academic sources, and are of varying quality. Conclusions SROI is a credible method for measuring the value of wider social, economic and environment outcomes achieved from public health interventions. The Social Value Database and Simulator presents a collation of studies and analysis utilising innovative health economics methods. Key messages • Public Health Wales’ Social Value Database and Simulator collates economic evaluations of public health interventions, to be used by policy makers to enable improved investment in health and well-being. • Social Return on Investment is a credible method for measuring the wider impact created by public health interventions.
