III. Evaluate adherence rates for and satisfaction with the interventions. IV. Evaluate for treatment-related adverse events (e.g., nausea, motion sickness). SECONDARY OBJECTIVE: I. To determine effect sizes for depression, fatigue, and sleep disturbance, by comparing changes in the intervention group to changes in the control group, following the 4-week study. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients play Endeavor over 25 minutes daily 5 days a week for 4 weeks. ARM II: Patients play Words! over 25 minutes daily 5 days a week for 4 weeks.
