Following the reporting standards proposed by Simmons et al. (26), we reported all exclusions and every measure given. On the basis of the effect sizes documented in past research (1013), we set a minimum sample size of 200 graduating students, with the goal of recruiting as many graduating senior students as possible to examine our key hypotheses of interest.

We preregistered our hypotheses through the Open Science Framework (OSF; Our data and syntax are publicly available through the OSF: We preregistered three main hypotheses through the OSF as follows:

H1: Students who value time over money before graduation (at T1) will report greater SWB 1 year after graduation (at T2).

H2: Students who value time over money before graduation (at T1) will be more likely to pursue intrinsically motivated activities 1 year after graduation (at T2).

H3: Any effect of valuing time over money before graduation (at T1) on the happiness that students report 1 year after graduation (at T2) will be at least partially mediated by intrinsically motivated activity pursuit.

We also preregistered additional analyses to ensure that our results held controlling for gender, age, family SES, and materialism.

As described above, it was our goal to collect as many graduating student participants as possible. Thus, we used multiple methodologies to recruit participants. Sometimes, these methodologies restricted the number of measures that we could include (i.e., short surveys implemented by our university). Given this data collection strategy, we only preregistered analyses for measures that we were able to collect across all data collection opportunities.
