Aims
Online mindfulness programs may provide a mechanism to support between 30% and 54% of the cancer population who experience sub-clinical or clinical fear of cancer recurrence (FCR). This study determined the efficacy of MindOnLine, a 9-session mindfulness-based online program for people living with, and beyond, breast, prostate or colorectal cancer, in reducing FCR.
Methods
Randomised controlled trial comparing MindOnline with a wait-list control. Adults, ≥18 years, living in Australia, who had completed active treatment/surveillance for stages 1–3 breast, prostate or colorectal cancer, within the past 5 years, had internet access, and FCR Inventory (FCRI) severity scores ≥13 were eligible. MindOnLine incorporated education, mindfulness practices, and meditation. Outcomes were assessed at baseline, 9-weeks and 9-months post-recruitment. Linear mixed models assessed MindOnLine’s impact on primary (FCRI total score) and secondary (depression (PHQ-9) and anxiety (GAD-7)) outcomes.
Results
Overall, 358 participants were randomly assigned to MindOnLine (n=183) or wait-list control (n=175); 58% had breast, 26% prostate and 16% colorectal cancer; 52% were ≥60 years old; 69% were female. At 9-weeks, MindOnLine participants demonstrated a significantly larger reduction in FCRI total score (-5.5 points, 95% CI [-8.5, -2.4], p=0.0004); anxiety score (-1.3, [-2.2, -0.5], p=0.0024); and depression score (-1.4 points, [-2.3, -0.5], p=0.0019) compared to participants in the control group. Significant intervention effects were sustained at 9-months (FCRI: -4.8 points, [ 8.4, -1.2]; p=0.0095; anxiety: -1.2, [-2.2, -0.16], p=0.023; depression: -0.97, [-1.9, -0.02], p=0.044). When stratified by cancer type, MindOnLine reduced FCR in people living with breast (9-weeks and 9-months) and colorectal (71% female; 9-weeks) cancer, but not males with prostate cancer.
Conclusions
This trial fills a significant gap in the role of self-directed online support programs to address moderate-severe FCR. Further research is required to understand how mindfulness programs can be effective for all population groups.
