Governments around the world have adopted national policies and programs to improve health literacy. This paper examines progress in the development of evidence to support these policies from interventions to improve health literacy among community populations. Our review found only a limited number of studies (n=7) that met the criteria for inclusion, with many more influenced by the concept of health literacy but not using it in the design and evaluation. Those included were diverse in setting, population and intended outcomes. All included educational strategies to develop functional health literacy, and a majority designed to improve interactive or critical health literacy skills. Several papers were excluded because they described a protocol for an intervention, but not results, indicating that our review may be early in a cycle of activity in community intervention research. The review methodology may not have captured all relevant studies, but it provides a clear message that the academic interest and attractive rhetoric surrounding health literacy needs to be tested more systematically through intervention experimentation in a wide range of populations using valid and reliable measurement tools. The distinctive influence of the concept of health literacy on the purpose and methodologies of health education and communication is not reflected in many reported interventions at present. Evidence to support the implementation of national policies and programs, and the intervention tools required by community practitioners are not emerging as quickly as needed. This should be addressed as a matter of priority by research funding agencies.
Issue addressed Complex health promotion programs, which can have multilevels of implementation and multi‐components with nonlinear causal pathways, present many evaluation challenges. Traditional evaluation methods often fail to account for the complexity inherent in assessing these programs. In real‐world settings, evaluations of complex programs are often beset by additional constraints of limited budgets and short timeframes. Determining whether a complex program is successful and how a program worked requires evaluators of complex programs to adopt a level of pragmatism. Methods This paper describes a pragmatic evaluation approach used to evaluate the Get Healthy at Work workplace health promotion program, implemented in New South Wales, Australia. Using the program as a case study, we describe some key principles for applying a pragmatic evaluation approach and use these principles to develop an appropriate evaluation strategy. Results The evaluation includes multiple research methods to assess program outputs and implementation; and identify emergent program impacts, within constrained resources. The evaluation was guided by epistemological flexibility, methodological comprehensiveness and operational practicality. Conclusion Health promotion programs, such as state‐wide obesity prevention programs, require appropriate evaluation methods which address their inherent complexity amidst the real‐world evaluation constraints, and focuses on the essential evaluation needs. So what The main complex program evaluation principles are applicable to other multilevel health promotion programs, challenged by methodological and practical or political constraints.
BackgroundNon-communicable chronic diseases in Australia contribute to approximately 85% of the total burden of disease; this proportion is greater for Aboriginal communities. The Get Healthy Service (GHS) is effective at reducing lifestyle-based chronic disease risk factors among adults and was enhanced to facilitate accessibility and ensure Aboriginal cultural appropriateness. The purpose of this study is to detail how formative research with Aboriginal communities was applied to guide the development and refinement of the GHS and referral pathways; and to assess the reach and impact of the GHS (and the Aboriginal specific program) on the lifestyle risk factors of Aboriginal participants.MethodsFormative research included interviews with Aboriginal participants, leaders and community members, healthcare professionals and service providers to examine acceptability of the GHS; and contributed to the redesign of the GHS Aboriginal program. A quantitative analysis employing a pre-post evaluation design examined anthropometric measures, physical activity and fruit and vegetable consumption of Aboriginal participants using descriptive and chi square analyses, t-tests and Wilcoxon signed-rank tests.ResultsWhilst feedback from the formative research was positive, Aboriginal people identified areas for service enhancement, including improving program content, delivery and service promotion as well as ensuring culturally appropriate referral pathways. Once these changes were implemented, the proportion of Aboriginal participants increased significantly (3.2 to 6.4%). There were significant improvements across a number of risk factors assessed after six months (average weight loss: 3.3 kg and waist circumference reduction: 6.2 cm) for Aboriginal participants completing the program.ConclusionsWorking in partnership with Aboriginal people, Elders, communities and peak bodies to enhance the GHS for Aboriginal people resulted in an enhanced culturally acceptable and tailored program which significantly reduced chronic disease risk factors for Aboriginal participants. Mainstream telephone based services can be modified and enhanced to meet the needs of Aboriginal communities through a process of consultation, community engagement, partnership and governance.
BackgroundHealth insurers worldwide implement financial incentive schemes to encourage health-related behaviours, including to facilitate weight loss. The maintenance of weight loss is a public health challenge, and as non-communicable diseases become more prevalent with increasing age, mid-older adults could benefit from programs which motivate weight loss maintenance. However, little is understood about their perceptions of using financial incentives to maintain weight loss.MethodsWe used mixed methods to explore the attitudes and views of participants who had completed an Australian weight loss and lifestyle modification program offered to overweight and obese health insurance members with weight-related chronic diseases, about the acceptability and usefulness of different types of financial incentives to support weight loss maintenance. An online survey was completed by 130 respondents (mean age = 64 years); and a further 28 participants (mean age = 65 years) attended six focus groups.ResultsBoth independent samples of participants supported a formalised maintenance program. Online survey respondents reported that non-cash (85.2%) and cash (77%) incentives would be potentially motivating; but only 40.5% reported that deposit contracts would motivate weight loss maintenance. Results of in-depth discussions found overall low support for any type of financial incentive, but particularly deposit contracts and lotteries. Some participants expressed that improved health was of more value than a monetary incentive and that they felt personally responsible for their own health, which was at odds with the idea of financial incentives. Others suggested ongoing program and peer support as potentially useful for weight loss maintenance.ConclusionsIf financial incentives are considered for mid-older Australian adults in the health insurance setting, program planners will need to balance the discordance between participant beliefs about the individual responsibility for health and their desire for external supports to motivate and sustain weight loss maintenance.Electronic supplementary materialThe online version of this article (10.1186/s12889-018-5136-z) contains supplementary material, which is available to authorized users.
