Some subjects will only receive the GOALS intervention.

The EDU intervention involves education on brain health and functioning in a classroom format, with study materials for homework. Some subjects will start with EDU and then cross-over to the GOALS.

Based on this trial design, predict the completion outcome and termination type (if applicable).
