all scales except for avoidant coping (HADS‐T = 0.87, CWC = 0.91,
Active Coping = 0.79, Avoidant Coping = 0.58, MOS‐SSS = 0.93).
All iCBT participants who preferred carer access were married
and had early‐stage breast cancer at diagnosis. All carers were
spouses with ages ranging from 40 to 66 (M = 50, SD = 11.63).

Completers versus non‐completers
There was no significant relationship between drop‐out and group
allocation, χ
2
(2) = 1.31, p = 0.520. Significant differences between
study completers (n = 47) and non‐completers (n = 25) were found.
Having another medical condition was associated with non‐
completion (χ
2
(1) = 6.19, p = 0.013) with a medium effect size
(Cramer's V = 0.29). High level of education was associated with
completion (χ
2
(4) = 11.19, p = 0.024) with a large effect size (Cramer's
V = 0.39); a higher proportion of completers had bachelor's, master's,
or PhD degree. Non‐completers had higher HADS‐D scores at
baseline (M = 7.68, SD = 4.55) than completers (M = 5.64, SD = 3.17).
Completers reported greater use of active coping (M = 2.73,
SD = 0.45) than non‐completers (M = 2.47, SD = 0.57). No other
significant differences were found in baseline outcome measures.
