Change Processes During Cognitive Bias Modification for Obsessive Compulsive Beliefs

摘要: Multiple studies have found that cognitive bias modification (CBM) can be an effective intervention to reduce maladaptive, anxiety-linked biases and symptoms, but little is known about how it achieves its effects. CBM posited work by altering contingency learning potential threat cues, rather than via habituation of fear arousal (as hypothesized for exposure-based interventions). In the current study, multi-level modeling was used examine trajectories change processes over course interpretation in a sample high obsessive–compulsive (OC) symptoms (n = 75). Psychophysiological (heart rate galvanic skin response), subjective fear, development learned between ambiguity tied safe outcomes were measured before, during, after CBM. Results showed that, compared control group, at reducing OC beliefs (though not responses subsequent stressors). Additionally, as expected, only significantly changed function training condition, while did not. Moreover, post-training indicators predicted extent from pre- “positive” group (and group). This indicates likely operating similarly habituation, instead marked processing. However, fully mediate effect this on beliefs, suggesting more needed understand mechanisms underlying
