The original list of 18 maladaptive schemas was published by Jeffery Young in 2003 and he subsequently developed the Young Schema Questionnaire to assess these schemas within patients. However, Yalcin, Marais, Lee and Correia (2022) completed further analysis of the questionnaire and identified that the questionnaires fit better by reducing the number of items and changing a few of the schema subsets. Hence, this list shows the revised list of 20 maladaptive schemas.

These extra schemas come from changes to the Emotional Inhibition schema, which was split into 'Emotional Constriction" and 'Fear of Losing Control'. The Punitiveness schema was also split into 'Punitive-Self' and 'Punitiveness- Others'.

While there is nothing wrong with the original list of schemas or using the YSQ-L3 or YSQ-S3, this latest review of the data would support swapping out the old for the new and using the YSQ-R as it is more statistically robust and the changes to the aforementioned schemas are more clinically relevant.
