- Dropped: Schwartz values questions, first-stage ayahuasca experience measures (except meaningfulness of experience), trip characteristics
- Added: dictator game, major decisions, what would you choose vs. what would make you happy, whether relationship mentioned at baseline has improved, work hours, measures of self-knowledge, and incentivized measure of social image concerns

[Update Jan 2024] Measured six months after treatment:
- Depression, happiness, flourishing
- Major decisions, social image self-report, relationship improvement, dictator game
- Work-related outcomes: employment status, occupation, hours, income, etc. [likely for a separate, future paper with linked RAIS administrative data (there is a delay before we can link the RAIS data for the current year)]
