Eight weekly group brain health sessions lasting 90-120 minutes. The intervention is psychoeducational, and each week presents information from NIH regarding factors that may promote cognitive health in late life (e.g., sleep, physical activity, social engagement and leisure, cognitive training). Weekly sessions are supplemented with educational videos and group discussion. Weekly homework consists of readings about brain health.

Participants in both interventions receive all study measures equivalently at all occasions

Eight weekly group mindfulness sessions lasting 90-120 minutes, along with a ½ day Mindfulness Retreat at the end of the training period, will include 1) psychoeducation, 2) formal exercises in the form of guided practice mentioned above, and 3) thoughtful exploration of ideas and questions. Formal mindfulness training will follow 21 guided pre-recorded meditative Moving Picture Experts Group Layer-3 Audio (MP3) tracks from the authors for use in class and at home, promoting both fidelity to the model and uniformity in intervention across training groups. Mindfulness activities in the protocol include mindful breathing, eating, walking, and various other practices well documented in the literature to promote mindfulness. Participants will be asked to practice mindfulness on their own time, and to log this.

Participants receive all of the same measures as the active comparator "Brain Health" condition in Weeks 1-14. In weeks 4-11, participants receive Mindfulness Inspired Treatment

Mixed effects models were used. Independent variables were linear and quadratic time/occasion, intervention group, and group-by-time interactions if appropriate. Preparatory to modeling, preliminary unconditional models were run to determine best fitting approaches for repeated and random covariance structures. Diagonal repeated covariance was best (heterogeneous variance over time, and no residual cross-time covariances).

F(1,34) = 0.96, p = .333, no adjustments.

A priori threshold for statistical significance was set at p < .05. No adjustment was made for multiple comparisons. The critical effect of interest evaluated here was the Linear Occasion (1-14) x Group (Brain Health vs. Mindfulness) interaction.
