Effects of changing dysfunctional beliefs in avatar-based cognitive therapy on symptoms of obsessive-compulsive disorder

INTERVENTION: Group 1: Intervention group: The participants in the intervention group have the task of interacting with an avatar. The avatar presents them with three of their own dysfunctional beliefs and corresponding positive alternatives. The participants' task is to contradict the dysfunctional beliefs by expressing the positive alternative assumptions. The dysfunctional beliefs are collected by the participants after an initial psychoeducational session on dysfunctional beliefs. Group 2: Control group: In contrast to the intervention group, the control group was presented with nonsense statements with no emotional valence (e.g. “Hamburg is the capital of Germany”). The participants in the control group have the task of contradicting these statements with alternative, functional beliefs.
