About

Psychological studies have shown that individuals tend to attribute causes of positive and negative events differently. Specifically, individuals hold an internalising or externalising bias of attribution which, in the case of particular patient groups, was found to polarize to the extreme. Such extreme attributional styles have found to have a direct impact on emotions, leading to a waning course of psychiatric disorders. This project aims to further examine the theoretical links between attributions and emotions using a transdiagnostic approach, and the effect of a 4-session process-based intervention on attributional biases.
