a
Estimated as least squares means from mixed model containing time (T0, T1, T2) and treatment condition (relaxation, worry practice, cognitive restructuring, telecoaching) and first-order time × treatment condition interaction terms. CI = confidence interval; FCRI = Fear of Cancer Recurrence Inventory; T0 = baseline; T1 = 4 weeks; T2 = 8 weeks.
b
P value from 2-sided t test of linear contrast of least squares means.
