ACT-group for Stroke Survivors (Pilot Study)
The goal of this clinical pilot trial is to test the feasibility, acceptance and preliminary efficacy of an adapted group psychotherapy manual in stroke survivors with psychological stress. The main questions it aims to answer are:

Is the group therapy feasible?
Is the group therapy accepted by stroke survivors and therapists?
Are there first indications on the efficacy of the group therapy to improve mental health?

Participants will take part in 8 weekly group therapy sessions of 90 minutes each.
