β Estimates refer to the difference in total recall weighted score (from possible of 12.5) explained by each predictor of interest.
Multivariate model 1 estimates are adjusted for time between feedback and recall interview and feedback condition.
Multivariate model 2 estimates are adjusted for all other variables in the model.
