Interventions to address FCR need to be effective but also accessible and low cost. This randomized controlled trial evaluated the efficacy of an online group\u2010based psychological intervention for FCR (ConquerFear\u2010Group).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Eligible breast cancer (BC) survivors had completed primary treatment 3\u00a0months\u20135\u00a0years previously, were \u226518\u00a0years, and scored \u226522 on the Fear of Cancer Recurrence Inventory\u2013Short Form (FCRI\u2010SF). Participants were randomized to online ConquerFear\u2010Group (focusing on metacognitive strategies, values\u2010clarification, and education about follow\u2010up behavior) or online group\u2010based relaxation training (active control). Questionnaires were completed at baseline (T1), 1\u00a0week post\u2010intervention (T2), three (T3) and six (T4) months later. The primary outcome was FCR (FCRI total). A number of secondary and process outcomes were also collected. Treatment effects were evaluated with mixed linear models.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of 866 eligible BC survivors, 475 (55%) completed the FCR screening, and 85 (18%) were randomized to ConquerFear\u2010Group or relaxation training (2\u00a0\u00d7\u00a06 groups). Compared with control participants, ConquerFear\u2010Group participants experienced larger reductions in FCR (Cohen's <jats:italic>d<\/jats:italic>\u00a0=\u00a00.47, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.001) and FCR severity (<jats:italic>d<\/jats:italic>\u00a0=\u00a00.57, <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001), as well as mindfulness and decentering from baseline through follow\u2010up, and improvements in emotion regulation (T2), worry (T2, T3) and rumination (T2) at some time points.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The results demonstrated statistically significant and stable effects of ConquerFear\u2010Group on FCR that were maintained over a 6\u2010month period.
