What do low-dysfunctional beliefs obsessive-compulsive disorder subgroups believe?

Area of Science:

• Psychiatry
• Clinical Psychology
• Cognitive Neuroscience

Background:

• Obsessive-compulsive disorder (OCD) is heterogeneous, with some patients lacking key dysfunctional beliefs.
• Understanding this heterogeneity is crucial for clinical and theoretical advancements in OCD.
• Previous research posits specific metacognitive beliefs and

Purpose of the Study:

• To investigate the cognitive and experiential characteristics of an OCD subgroup with low dysfunctional beliefs.
• To differentiate this low-belief OCD subgroup from a high-belief subgroup and comparison groups.
• To explore the roles of metacognitive beliefs and "not just right experiences" (NJREs) in OCD variants.

Main Methods:

• Evaluated metacognitive beliefs using the Metacognitions Questionnaire (MCQ-30).
• Assessed "not just right experiences" (NJREs) as indicators of emotional/sensory feedback processing.
• Compared low-belief OCD (OCD-L), high-belief OCD (OCD-H), anxious, and student groups.

Main Results:

• Metacognitions Questionnaire (MCQ-30) scores differentiated OCD subgroups, primarily characterizing the OCD-H group.
• "Not just right experiences" (NJREs) scores also differentiated OCD subgroups.
• NJREs were consistently linked to OCD symptoms specifically within the OCD-L subgroup.

Conclusions:

• Findings support theoretical models suggesting distinct motivations in OCD variants.
• Harm avoidance and NJREs appear to be important, separate drivers for specific OCD presentations.
• Metacognitive beliefs are more characteristic of high-belief OCD subgroups, while NJREs are particularly relevant to low-belief OCD.
