Experimental: Intervention group

The intervention group will be assessed with the study surveys at baseline (T1), will participate in the online MBSR intervention for the next 6 weeks, and will be subsequently reassessed with the study surveys at 7 weeks (T2) and at 11 weeks (T3) of follow-up.

No_intervention: Wait-list control group

A wait-list control group will be used with the objective that all participants have the opportunity of receiving the online MBSR intervention and at the same time allow comparison of the effectiveness of the program with a group without intervention. Given that treatment-related stress has an important negative impact on patients' wellbeing, it is appropriate to offer the control group the possibility of receiving the intervention if its effectiveness is demonstrated.~The control group will be assessed with the study surveys at baseline (T1), will not participate in the online MBSR intervention for the next 6 weeks, and will be subsequently reassessed with the study surveys at the same timepoints as the intervention group at 7 weeks (T2) and at 11 weeks (T3) of follow-up. Upon completion of recruitment and follow-up of all participants, the study will end, and the control group will be able to receive the online MBSR intervention according to their preference.
