OCD: 13 questionnaires and rating scales

This tool is used to assess the severity of obsessive and compulsive symptoms in patients with obsessive-compulsive disorder (OCD). Developed by researchers at Yale University, this scale is recognized for its reliability and validity in diagnosing OCD and monitoring its course.

The DOCS is a self-report questionnaire designed to measure the severity of obsessive-compulsive symptoms across four key dimensions: contamination, responsibility for harm, unacceptable thoughts, and symmetry/completeness. The tool is used for differential diagnosis, initial assessment, and treatment monitoring of obsessive-compulsive disorder in adults.

The Leyton Obsessional Inventory is a self-report questionnaire designed to identify and quantify obsessive and compulsive symptoms and their impact. Historically widely used in clinical psychology and psychiatry, it explores the presence of intrusive thoughts, doubts, checking, rituals, orderliness, cleanliness, and other manifestations of the obsessive spectrum. It provides an overall estimate of the symptoms and the associated distress, but its interpretation must remain clinical and be supplemented by an interview.

The TCQ is a self-report questionnaire measuring the strategies a person uses to control unwanted and intrusive thoughts. It identifies the cognitive mechanisms involved in managing intrusive thoughts, which are frequently studied in anxiety and obsessive-compulsive disorders. Five dimensions are assessed: distraction, self-focus, punishment, social concern, and reappraisal.

The Thought-Action Fusion Scale (TAFS) is a self-report questionnaire used mainly in clinical psychology to assess an individual's tendency to confuse thoughts and actions. This cognitive bias, often present in obsessive-compulsive disorder, is measured across two dimensions: moral thought-action fusion (thinking about a bad action is as serious as doing it) and likelihood thought-action fusion (thinking about a negative event increases the likelihood that it will happen).

The OBQ-44 is a self-report questionnaire designed to assess the dysfunctional beliefs associated with obsessive-compulsive disorder (OCD). It measures three main dimensions: responsibility/overestimation of threat, perfectionism/intolerance of uncertainty, and overimportance/power of thoughts. It is useful for identification and cognitive formulation in the treatment of OCD.

The OCI-R is a self-report questionnaire used to detect obsessive and compulsive symptoms and measure their severity. It includes several subscales corresponding to the dimensions frequently observed in obsessive-compulsive disorder (OCD), such as washing, checking, ordering, obsessing, rumination, and hoarding.

The Padua Inventory-Revised (PI-R) is a self-report questionnaire designed to measure the severity and type of obsessive-compulsive symptoms. It is widely used in clinical assessment and in research on obsessive-compulsive disorder (OCD). It identifies different symptom dimensions such as rumination, checking compulsions, contamination and impulsivity.

The CY-BOCS is a semi-structured clinical interview scale designed to assess the severity and types of obsessive and compulsive symptoms in children and adolescents. It makes it possible to measure symptom change before and after therapeutic intervention, clearly distinguishing frequency, intensity, interference, and resistance.

The Maudsley Obsessive-Compulsive Inventory (MOCI) is a self-report questionnaire designed to measure the severity and presence of obsessive and compulsive symptoms typical of obsessive-compulsive disorder (OCD). It includes subscales targeting the main aspects of OCD, such as checking, cleaning, ordering, and doubting.

The Obsessive Intrusions Inventory assesses the frequency, distress, and perceived control of intrusive obsessional thoughts in adults. It helps appraise the intrusive nature of certain mental contents frequently encountered in obsessive-compulsive disorder (OCD) and in the general population. The tool contains statements covering different themes of obsessional intrusions. It can help differentiate normal from pathological intrusions.

The WBSI is a self-report questionnaire designed to measure an individual's tendency to deliberately suppress unwanted thoughts. It is frequently used to assess the cognitive processes related to thought suppression, which may be involved in anxiety disorders and obsessive-compulsive disorders. Its name refers to Daniel Wegner's famous experiment in which participants, asked not to think about a white bear, paradoxically ended up thinking about it more.

The VOCI is a self-report questionnaire designed to measure the severity and variety of obsessive-compulsive symptoms. It makes it possible to assess several dimensions of obsessive-compulsive disorder (OCD), including the extent of obsessional thoughts and compulsive rituals, as well as other associated symptoms such as checking, contamination, order and symmetry.
