Non-just-right experiences are more closely related to OCD than tics in Tourette patients

Complex tics and obsessive or compulsive behaviour can be difficult to differentiate diagnostically. The majority of adult patients with Tourette syndrome report experiencing premonitory urges before tics. Some of these experiences have been linked to non-just-right experiences (NJRE), which are frequently reported by patients with obsessive-compulsive disorder or behaviours (OCD/OCB). We aimed to assess whether NJRE are more closely related to tics and tic-associated premonitory urges or whether they are more closely associated with OCD. A total of N = 111 patients (mean age = 34.77 + /-12.93; N = 37 female) with a confirmed diagnosis of Tourette syndrome completed the premonitory urges for tic disorders scale (PUTS), the revised non-just-right experiences scale (NJRE-QR), and questionnaires regarding their tic severity, and comorbid OCD/OCB. A multi-trait-multi-methods matrix was calculated to examine associations amongst scales measuring tic-related and OCB-related phenomena. The PUTS correlated overall higher with tic questionnaires than with OCD/OCB questionnaires. The NJRE correlated higher with OCD symptoms than with tic severity. The results indicate that non-just-right experiences are more closely associated with comorbid OCB than with tics in patients with Tourette syndrome.

Screening dysfunktionaler Überzeugungen bei Zwangsstörungen

Hintergrund

Dysfunktionale Überzeugungen und Bewertungen von Zwangsgedanken sind ausschlaggebend für die Entstehung und Aufrechterhaltung von Zwangsstörungen. Die reliable und valide Erfassung dieser Überzeugungen mithilfe von Screeningverfahren ist für die kognitiv-verhaltenstherapeutische Behandlung relevant.

Fragestellung

Ziel der Arbeit war die Erstellung eines Scoping review bezüglich der aktuellen Screeninginstrumenten zur Erfassung der 6 von der Obsessive Compulsive Cognitions Working Group (OCCWG) vorgeschlagenen Domänen bei Zwangsstörungen. Die Verfahren wurden systematisch nach ihrer psychometrischen Güte bewertet und in ihren Eigenschaften verglichen.

Material und Methoden

Die Literatursuche erfolgte in den Datenbanken Web of Science Core Collection, Google Scholar und PubMed. Eingeschlossen wurden deutsch- und englischsprachige Verfahren für Erwachsene (≥18 Jahre).

Ergebnisse

Es konnten 56 Studien zur Überprüfung der psychometrischen Eigenschaften von 16 Fragebogen eingeschlossen werden. Die Fragebogen erfassten alle Domänen dysfunktionaler Überzeugungen. Außerdem lagen 4 domänenübergreifende Verfahren vor, und 9 der Fragebogen waren deutschsprachig. Die Mehrzahl der Screeningverfahren wies adäquate bis gute psychometrische Werte auf. Die methodische Qualität der Studien war heterogen; methodische und statistische Verfahren nahmen über die Jahre an Komplexität zu.

Schlussfolgerung

Weiterer Forschungsbedarf besteht v. a. in der Untersuchung der Störungsspezifität und Änderungssensitivität von Screeningverfahren an klinischen Stichproben.

Phenomenology of Obsessive-Compulsive Disorder: A Methodologically Structured Overview

A methodological order is derived from the concept of phenomena and stages of understanding are developed according to Karl Jaspers. The three levels of descriptive, genetic and hermeneutic understanding are applied to the study of obsessive-compulsive disorder. Descriptive understanding essentially reveals a sense of incompleteness and depersonalization that underlies the experience of the nonsense of obsessive thoughts and that obsessive-compulsive symptoms do not come to an end. Genetic understanding shows particularly by reference to the trigger situation that sensitivity, undifferentiated affects, affective hyperarousal and traumatization are important aspects in the development and maintenance of the obsessive-compulsive disorder. Hermeneutic understanding brings to light the fear of death in obsessive-compulsive disorder as its anthropological dimension. The aim of this methodologically structured overview is to focus on the experience of the obsessive-compulsive patient, to keep curiosity and interest alive, so that both research and relationship to the patient is stimulated.

Sensory over responsivity and obsessive compulsive symptoms: A cluster analysis

BACKGROUND

Several studies have examined the sensory component in Obsesseive Compulsive Disorder (OCD) and described an OCD subtype which has a unique profile, and that Sensory Phenomena (SP) is a significant component of this subtype. SP has some commonalities with Sensory Over Responsivity (SOR) and might be in part a characteristic of this subtype. Although there are some studies that have examined SOR and its relation to Obsessive Compulsive Symptoms (OCS), literature lacks sufficient data on this interplay.

OBJECTIVES

First to further examine the correlations between OCS and SOR, and to explore the correlations between SOR modalities (i.e. smell, touch, etc.) and OCS subscales (i.e. washing, ordering, etc.). Second, to investigate the cluster analysis of SOR and OCS dimensions in adults, that is, to classify the sample using the sensory scores to find whether a sensory OCD subtype can be specified. Our third goal was to explore the psychometric features of a new sensory questionnaire: the Sensory Perception Quotient (SPQ).

METHOD

A sample of non clinical adults (n=350) was recruited via e-mail, social media and social networks. Participants completed questionnaires for measuring SOR, OCS, and anxiety.

RESULTS

SOR and OCI-F scores were moderately significantly correlated (n=274), significant correlations between all SOR modalities and OCS subscales were found with no specific higher correlation between one modality to one OCS subscale. Cluster analysis revealed four distinct clusters: (1) No OC and SOR symptoms (NONE; n=100), (2) High OC and SOR symptoms (BOTH; n=28), (3) Moderate OC symptoms (OCS; n=63), (4) Moderate SOR symptoms (SOR; n=83). The BOTH cluster had significantly higher anxiety levels than the other clusters, and shared OC subscales scores with the OCS cluster. The BOTH cluster also reported higher SOR scores across tactile, vision, taste and olfactory modalities. The SPQ was found reliable and suitable to detect SOR, the sample SPQ scores was normally distributed (n=350).

CONCLUSIONS

SOR is a dimensional feature that can influence the severity of OCS and may characterize a unique sensory OCD subtype.
