Multi-session, Personalized Cognitive Bias Modification for Thought-Action-Fusion

CBM-TAF aims to modify TAF by training participants to adopt an interpretation style that is inconsistent with TAF (i.e., having unwanted thoughts is not morally equivalent to acting upon them and/or having unwanted thoughts does not increase the likelihood of feared events happening in real life). To personalize the training, CBM-TAF is designed to address 4 subtypes of OCD (as defined by Dimensional Obsessive-Compulsive Scale; Abramowitz et al., 2010), each of which targets either TAF-moral or TAF-likelihood. Participants will indicate two OCD subtypes that are most relevant to their experiences and only complete scenarios that correspond to their chosen subtypes. For each scenario, participants are instructed to enter a missing letter in a fragmented word and resolve its emotional ambiguity. After then, participants will answer a True/False question related to the given scenario to verify their comprehension and consolidate their acquisition of healthier interpretation style.

CBM-SMP is a comparable intervention to CBM-TAF (Siwiec et al., 2023), which aims to provide general education about stress and stress management techniques. It is identical to CBM-TAF in terms of its administration, except for the content of scenarios included in training sessions. For each scenario, participants are instructed to enter a missing letter in a fragmented word. After then, participants will answer a True/False question related to the given scenario in order to verify their comprehension.
