Brief summary: This study aims to analyze the effects of a psychological intervention to promote wellbeing. To do so, a brief intervention is developed to enhance a sense of gratitude through a multiple baseline across components design. Traditional measures will be used together with the incorporation of a novel evaluation methodology such as the EMA, which allows the collection of data in the context of people's daily lives and at different specific times, that is, in real time.
