Evidence

Fernandes 2014 reports that financial-literacy interventions explained about 0.1% of the variance in financial behaviours, with effects decaying over time, and suggests a narrower just-in-time role tied to specific behaviours; Miller 2015 reports effects on savings and record-keeping but not on credit default.

In observational studies, financial strain is associated with physical and biological outcomes — oxidative stress, inflammation, blood-pressure and metabolic profiles, self-rated health and mortality — and long-term hardship with poorer late-life health (Samuel 2024; Kahn 2006).

Reviews and studies report financial strain associated with depression (Guan 2022), serious psychological distress (Tsuchiya 2020) and suicide risk (Roelfs 2023), which Roelfs 2023 reports as weak after accounting for physical and mental health.

Job clubs, welfare-rights advice, guaranteed income, financial coaching and energy-efficiency schemes are the interventions these sources studied; Birkenmaier 2026 reports that most financial effects of coaching were small, with a mix of significant and non-significant results, and Yashadhana 2023 reports holistic initiatives that met basic needs first aligned with positive financial-wellbeing outcomes.

The financial-strain-to-health link is conditioned by psychosocial resources: tangible social support buffered it (Åslund 2014), and sleep problems mediated and moderated it (Chai 2025); in cross-sectional studies, self-efficacy, resilience and self-control appear in models of financial and emotional well-being (Dare 2022; Curry 2025; Radianto 2026).

Financial well-being is described in reviews as a dynamic, multidimensional construct, studied mostly as a subjective state, whose definition and measurement are still disputed.

A weekly money check-in paired with a short self-regulation practice: Lehrer 2024 reports a small-to-moderate physiological effect of psychological stress management among the financially stressed.

Instead of long courses, learn one specific money concept right when you need it, e.g., how interest works before taking a loan; Fernandes 2014 suggests a narrower just-in-time role for financial education, tied to specific behaviours.

Recording what you spend for a few weeks: record-keeping is one of the areas where Miller 2015 reports financial-capability interventions had a positive impact.
