ABSTRACT
This chapter explores the conditions that make a person vulnerable to the development of Obsessive-Compulsive Disorder (OCD). It examines life experiences, especially relationships, which contribute to the catastrophic representation of deontological guilt, which is a specific and necessary condition for the development of OCD. One of the lenses through which the etiopathogenesis of OCD has been observed is genetics. Interpersonal context, family atmosphere, and certain styles of childrearing can constitute the ground in which cognitive vulnerability to OCD takes root. A family atmosphere characterised by parental control and criticism, high expectations, the push toward perfectionist standards, may contribute to the creation of perfectionist beliefs in children. Critical and demanding parenting styles can be considered as a vulnerability factor in the development of obsessive beliefs and behaviours. Elevated levels of criticism characterise the family environments of OCD patients, both paediatric and adult.
