Highlights
– A therapist‑guided online intervention (TG‑iConquerFear) produced large, clinically meaningful reductions in overall fear of cancer recurrence (FCR) among colorectal cancer survivors with clinical FCR.
– At 3 months postintervention the between‑group difference in FCRI total score was 19.1 points (95% CI, 10.0–28.3; P < .001) with a standardized effect size (Cohen d) of 0.62.
– 81% of TG‑iConquerFear participants fell below the clinical FCR cutoff on the FCRI‑SF versus 43% with augmented self‑help (number needed to treat = 3).
