FCRI Fear of Cancer Recurrence Inventory; CARS Concerns about Recurrence Scale.
aReflects the proportion of days on which participants responded affirmatively. Sleep variables were derived by averaging each participant’s daily sleep. Top panel: Bivariate correlations among variables, with inter-correlations among Burst 1 variables shown before the slash and inter-correlations among Burst 2 variables shown after the slash (i.e., Burst 1/Burst 2). Correlations among survivors’ variables are below the diagonal (shaded light gray), correlations among partners’ variables are above the diagonal (shaded dark gray), and correlations between survivors’ and partners’ variables are in parentheses along the diagonal. Bottom panel: Means and SDs for survivors’ and partners’ variables are shown before and after the slash, respectively (i.e., survivor/partner). For Burst 1, all r> .23, p < .05. For Burst 2, all r > .28, p < .05. Burst 1 N = 76 couples. Burst 2 N = 57 couples. Correlations and mean differences between variables measured at burst 1 vs. burst 2 are not shown above but described in the main text.
