Means with different superscripts are significantly different for within participant comparisons at the level of p < 0.05

Significance of F test **p < 0.0001

^† indicates altered degrees of freedom 1.6, 136.1 with Greenhouse–Geisser correction

Effect size for partial eta squared (η_p²) can be described as the following: small = 0.01–0.05, medium = 0.06–0.13, 0.14 = large =  ≥ 0.14

FCR, fear of cancer recurrence; QoL, quality of life; PHQ-9, Patient Health Questionnaire (9 items); GAD-7, Generalised Anxiety Disorder Assessment (7-items); T1, pre-intervention; T2, post-intervention; T3, 12 weeks following intervention
