CANCER
The current study is one of the few studies that investigate the effect of an online self-help training for FCR with a follow-up of 24 months. Results indicate no change of both FCR and PD across time, for both the intervention and CAU group, nor any effect of the intervention on the relation between FCR and PD, nor did we find a class of participants that benefitted from our online self-help training. Although some This result is largely in line with a recent literature review about online interventions aimed at reducing FCR and PD in cancer patients. They found partial support for reduction in PD, and limited evidence for reducing anxiety after online interventions [The baseline correlations between FCR and PD that we found in this study, were in line with previous research [Moreover, we identified five latent classes that capture different patterns in FCR across time. Our results showed quite stable FCR trajectories for four of the latent classes over time (stable severe, moderate, mild, and low FCR). One of the classes has moderate baseline FCR and starts to decrease 6 months after the intervention, but we do not expect this to be an effect of our online self-help training. Recently, some studies have been published about FCR classes and trajectories [
