Treating incompleteness in obsessive-compulsive disorder: a meta-analytic review
Publication date: Available online 8 August 2018Source: Journal of Obsessive-Compulsive and Related DisordersAuthor(s): Rachel A. SchwartzAbstractIncompleteness (INC) is a prevalent, impairing subtype of obsessive-compulsive disorder (OCD) in which rituals are performed to counteract “not just right” sensations. Although individuals with INC may be most in need of treatment, conventional OCD interventions emphasize harm avoidance (HA) over INC, contributing to the pervasive assumption that INC is treatment resistant. However, this assumption has not been adequately tested. This paper presents the first meta-analytic in...

Disgust sensitivity mediates the effects of race on contamination aversion
Publication date: Available online 7 August 2018Source: Journal of Obsessive-Compulsive and Related DisordersAuthor(s): Jamilah R. George, Christopher Pittenger, Benjamin Kelmendi, Jeffrey M. Lohr, Thomas G. AdamsAbstractAfrican Americans report greater contamination aversion than European Americans. Few studies have attempted to identify potential causes for this elevated contamination aversion, though existing research and theory suggests this may be partly due to concomitant heightened disgust sensitivity. The present study examined the relations between race, disgust sensitivity, and contamination aversion among Africa...

Challenges in Diagnosis and Treatment of Olfactory Reference Syndrome: A Case Study
This study describes the case of a 20-year-old male who was diagnosed with ORS after excluding other differential and treated using combination strategies that included selective serotonin reuptake inhibitors (SSRI) and cognitive behavioral therapy (CBT). Following 16 weeks of treatment, the patient showed significant improvement in his functioning, which was measured with different scales. The scales were used to measure anxiety and depression revealed the patient was below clinical threshold levels. The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), used to measure the severity of obsessive-compulsive disorder (OCD) sym...

Emotion Regulation and Obsessive-Compulsive Phenomena in Youth
Publication date: Available online 21 July 2018Source: Journal of Obsessive-Compulsive and Related DisordersAuthor(s): Noah Chase Berman, Ashley M. Shaw, Erin E. Curley, Sabine WilhelmAbstractThere is a dearth of research evaluating the relationship between obsessive-compulsive (OC) phenomena and emotion regulation (ER) in youth. The current study bridges this gap by utilizing multiple informants to evaluate the relationship between ER processes (e.g., suppression) and OC features in 27 diagnostically-assessed youth. As predicted, after controlling for children's age and distress, obsessive beliefs (e.g., the importance of...

Experiential Avoidance in the Context of Obsessions: Development and Validation of the Acceptance and Action Questionnaire for Obsessions and Compulsions
Publication date: Available online 18 July 2018Source: Journal of Obsessive-Compulsive and Related DisordersAuthor(s): Ryan J. Jacoby, Jonathan S. Abramowitz, Jennifer Buchholz, Lillian Reuman, Shannon M. BlakeyAbstractThe unwillingness to remain in contact with obsessions and anxiety (i.e., experiential avoidance, EA) may explain how normally occurring unwanted intrusive thoughts develop into clinical obsessions as seen in obsessive-compulsive disorder (OCD). Studies examining the relationship between EA and OC symptoms are mixed, potentially because the existing self-report measure of EA (i.e., the Acceptance and Action ...

Clarifying the thought-action fusion bias in obsessive-compulsive disorder
Publication date: Available online 31 October 2017Source: Journal of Obsessive-Compulsive and Related DisordersAuthor(s): Dianne M. Hezel, S. Evelyn Stewart, Bradley C. Riemann, Richard J. McNallyAbstractStudies indicate high levels of thought-action fusion (TAF) in OCD. The current study aimed to determine if people with OCD evaluate others’ thoughts the same way as their own, as existing measures do not test for this distinction. Forty-two non-anxious, 40 OCD, and 41 socially anxious participants completed self-report and behavioral measures of thought-action fusion. Findings indicated that self-report measures of TAF,...

Responsibility causes reassurance seeking, too: An experimental investigation
Publication date: Available online 1 November 2017Source: Journal of Obsessive-Compulsive and Related DisordersAuthor(s): Mark W. Leonhart, Adam S. RadomskyAbstractExcessive reassurance seeking (RS) in obsessive-compulsive disorder (OCD) has been conceptualized as compulsive checking by proxy. Manipulations of responsibility augment a range of OCD symptoms; however, their impact on RS behaviour has not been examined. We hypothesized that under conditions of high responsibility (HR), participants would report greater urges to seek reassurance and more actual reassurance seeking (RS) compared to low responsibility (LR) parti...

Intentional binding and obsessive-compulsive tendencies: A dissociation between indirect and direct measures of the sense of agency
This study examined whether obsessive-compulsive (OC) tendencies are related to an impaired sense of agency (SoA). We examined agency using both indirect (“implicit”) and direct (“explicit”) measures, aiming to tap into different aspects of the sense of agency. We measured the SoA of participants with high vs. low scores on a measure of OC symptoms indirectly using a task that assesses the intentional binding effect, i.e., the subjective compression of the temporal interval between a voluntary action and its external sensory consequence. We also measured participants' "illusory" SoA using a direct question about th...
