PROTOCOL: Financial Literacy Programmes for the Ageing Population: An Evidence and Gap Map.

This is the protocol for a Campbell evidence and gap map. The objectives are as follows: to identify and describe the available evidence on interventions designed to improve financial literacy, digital financial skills, financial decision-making, and resilience to fraud and abuse among older adults; map the scope and focus of existing research, including the type of interventions implemented, target populations, delivery modalities, and contextual factors; assess the quality of the types of evidence available, including randomised and non-randomised controlled trials, as well as qualitative studies exploring the effectiveness and acceptability of financial literacy interventions; identify evidence clusters where sufficient studies exist to support further synthesis (e.g., systematic reviews or meta-analyses) and highlight evidence gaps where additional primary research is most needed, and; provide a structured and accessible resource for policymakers, practitioners, researchers, and advocacy groups to inform the design, adaptation, and implementation of financial literacy programmes for older adults.
