aP-value for differential changes between time point (9 months compared to baseline) and group assignment, adjusted for patient education, care partner gender, and patient disease stage for intervention compared to control, and adjusted for patient disease stage and care partner employment status for active intervention versus non-active intervention.
bOdds ratios (95% CI) for the presence of anxiety or complete illness understanding at 9 months compared to baseline and mean differences (95% CI) in satisfaction with cancer care at 9 months compared to baseline.
cSymptoms of anxiety refer to a cutpoint of 3+ on the GAD-2.
dComplete illness understanding contrasts scores of 4 (4 out of 4 questions answered correctly) versus all others at 3 and 9 months.
