Ethics may offer another path to wellbeing – a route not yet investigated within Positive Psychology. In a pilot study with 181 US participants, we found a significant positive association between having a well-defined ethical framework and wellbeing, as measured by the Mental Health Continuum. The relationship held after controlling for religiosity and age and was fully mediated by the extent to which having an ethical framework helped an individual to make sense of the world. There were positive associations with subjective and social wellbeing, while the strongest correlation was with psychological wellbeing. To establish causality, a subsequent experimental study was conducted whereby 356 US participants were randomly assigned to either an ethical framework prime condition or an active control condition. While we did not find a main effect of condition, the extent to which participants initially had a well-defined personal ethical framework moderated the effects of condition on well-being. Specifically, those with a less well-defined ethical framework reported significantly higher well-being after receiving the ethical framework prime relative to those in the control. Collectively, these results provide preliminary evidence suggesting that a well-defined ethical framework can boost well-being by increasing coherence. Implications for ethical interventions will be discussed.
