Extended Data Table 7 Regression-estimated effects of each experimental condition on whether participants visited the gym in a given week during the four-week intervention period relative to the Placebo Control condition

From: Megastudies improve the impact of applied behavioural science

  1. The table reports the results of an ordinary least squares regression predicting whether participants visited the gym in a given week during the four-week intervention period with indicators for experimental condition during the four-week intervention period, participants fixed effects, and cohort-week interactions. Robust standard errors were clustered by participant. Observations in the regression were weighted to ensure that each condition was equally weighted within a cohort and each cohort was weighted proportionally to its length. The reference group was the Placebo Control condition. See Table S1 in the Supplementary Information for descriptions of each experimental condition. a, b, c, d, e These superscripts denote the different incentive amounts offered in different versions of the Bonus for Returning after Missed Workouts, Higher Incentives, and Rigidity Rewarded conditions, which are detailed in Table S1 in the Supplementary Information. In conditions with the same name, superscripts that come earlier in the alphabet indicate larger incentives.
