Maladaptive Consequences of Mental Intrusions with Obsessive, Dysmorphic, Hypochondriac, and Eating-disorders Related Contents: Cross-cultural Differences.

Abstract Background/Objective Unwanted mental intrusions (UMIs) with contents related to Obsessive-Compulsive Disorder (OCD), Body Dysmorphic Disorder (BDD), Illness Anxiety Disorder (IAD), and Eating Disorders (EDs) are highly prevalent, independently of the cultural and/or social context. Cognitive-behavioral explanations for these disorders postulates that the escalation from common UMIs to clinically relevant symptoms depends on the maladaptive consequences (i.e., emotions, appraisals, and control strategies) of experiencing UMIs. This study examines, from a cross-cultural perspective, the cognitive-behavioral postulates of the maladaptive consequences of having UMIs. Method Non-clinical 1,473 participants from Europe, the Middle-East, and South America completed the Questionnaire of Unpleasant Intrusive Thoughts to assess the maladaptive consequences of experiencing highly disturbing OCD, BDD, IAD, and EDs-related UMIs. Results Findings revealed main effects for both the country and the consequences associated with the four UMI contents. Interaction effects between the consequences of each UMI content and the sample location were also observed. Conclusions Cognitive-Behavioral models for OCD, BDD, IAD, and EDs should be implemented along with socio-cultural variables that increase the understanding of the role of these variables in the phenomenology of UMIs and their associated consequences.
