This study aims to examine whether a brief mindfulness of the breath meditation practice is more helpful than listening to an audio recording in relation to improving hope and gratitude in the general population.

This one-session online study will randomise members of the general public to either 1) a mindfulness of the breath meditation practice lasting 10 minutes or 2) an audio-recording control of the same length. State measures of mindfulness, hope and gratitude will be taken immediately before (baseline) and after the intervention/control. In addition, the study will also measure trait mindfulness at baseline.The primary hypothesis is that engaging in a brief mindfulness practice will result in beneficial changes in state hope compared to control. Other hypotheses are that: engaging in a brief mindfulness practice will result in beneficial changes in state gratitude compared to control; that the effect of mindfulness practice on state hope will be statistically mediated by change in state mindfulness; that the effect of mindfulness practice on state gratitude will be statistically mediated by change in state mindfulness; and that baseline trait mindfulness will statistically moderate the effect of mindfulness practice on change in state mindfulness in the above mentioned mediation models (i.e. that moderated mediation will be observed).

Inclusion Criteria:

• Members of the general public.
• Adequate understanding of spoken and written English.
• Internet access.

Exclusion Criteria:

-Currently experiencing very severe problems with their mental health.

Participants will be randomised and complete the study, including outcome measures, through an automated online programme, without involvement of the researcher.
