Primary Outcomes (Explanation)
|
Before
Depression and happiness are measured by, respectively, employing the Kessler Psychological Distress Scale (K10) and self-reported happiness on a scale from 1 to 7. We also elicit key first-stage measures to compare our participants’ experiences with the literature on clinical trials. For this matter, we use the Ego Dissolution Inventory (Nour et al. 2016), the Mystical Experience Questionnaire (Pahnke WN 1969), and a Meaningful Experience question (as in Griffiths 2006).
In the longer run, we are interested in four sets of outcomes. First, prosociality, which we measure through a Dictator Game. Second, trust, using a Berg et al. (1995) trust game. Participants’ choices will be implemented with a small but positive probability. Third, work-related outcomes, for which we ask participants to self-report their work satisfaction, working hours, employment status, intentions to leave their job, and to change careers. Finally, the likelihood of taking major life decisions (e.g. moving house, following Levitt 2021).
