The Obsessive Beliefs Questionnaire (OBQ): examination in nonclinical samples and development of a short version

The study aimed to examine the factor structure of the Obsessive Beliefs Questionnaire (OBQ), the most widely used measure of dysfunctional beliefs in obsessive—compulsive disorder (OCD). Multiple exploratory methods (exploratory factor analysis, cluster analysis by variable, multidimensional scaling) were used to examine the questionnaire. Confirmatory factor analyses were also performed in two large nonclinical samples from Australia (N = 1,234) and Israel ( N = 617). Our analyses suggested a four-factor solution with 38 items, where threat and responsibility formed separate dimensions (the “OBQ-TRIP”). This version had superior fit statistics across the two divergent confirmatory samples, when compared with four alternative models suggested by previous authors. Of the OBQ dimensions, the threat scale correlated most strongly with OCD symptom measures, even when controlling for depression. A short, 20-item version of the scale is offered for further study. Implications and limitations are discussed.

The relationship of cognitive confidence to OCD symptoms

The role of meta-memory and meta-cognition in obsessive-compulsive disorder (OCD) symptoms and checking was examined in a student sample, using the memory and cognitive confidence scale (MACCS; Nedeljkovic, M., & Kyrios, M. (2007). Confidence in memory and other cognitive processes in obsessive-compulsive disorder. Behaviour Research and Therapy, 45, 2899-2914). Confirmatory factor analysis supported the MACCSs previously reported structure, and hierarchical regression supported its relationship to OCD symptom severity over-and-above depression and other OCD-related beliefs. Specifically, general confidence in memory was found to be a unique predictor of overall OCD severity. Implications for theory and research are discussed.

Differences in neuropsychological performance between subtypes of obsessive―compulsive disorder

Objective: Neuropsychological studies have suggested that frontal–striatal dysfunction plays a role in obsessive–compulsive disorder (OCD), although findings have been inconsistent, possibly due to heterogeneity within the disorder and methodological issues. The purpose of the present study was therefore to compare the neuropsychological performance of different subtypes of OCD and matched non-clinical controls (NCs) on the Cambridge Automated Neuropsychological Test Battery (CANTAB). Methods: Fifty-nine OCD patients and 59 non-clinical controls completed selected tests from CANTAB examining executive function, visual memory and attentional-set shifting. Depression, anxiety and OCD symptoms were also assessed. Results: From 59 OCD patients, four subtypes were identified: (i) washers; (ii) checkers; (iii) obsessionals; and (iv) mixed symptom profile. Comparisons between washers, checkers, obsessionals and NCs indicated few differences, although checkers were generally found to exhibit poorer performance on spatial working memory, while obsessionals performed poorly on the spatial recognition task. Both checkers and the mixed subgroups showed slowed initial movement on the Stockings of Cambridge planning task and poorer pattern recognition relative to NCs. Conclusion: Overall the results suggested greater impairments in performance on neuropsychological tasks in checkers relative to other subtypes, although the observed effects were small and the conclusions limited by the small subtype samples. Future research will need to account for factors that influence neuropsychological performance in OCD subtypes.

Desire for Control, Sense of Control and Obsessive-Compulsive Symptoms

While control-related cognitions have often been implicated in discussions of Obsessive Compulsive Disorder (OCD), empirical investigations of the relationship between control-constructs and OCD symptoms have been relatively limited. In this article it was hypothesized that OCD symptoms may be linked with a higher desire to control (DC), but a lower sense of control (SC) over the self and environment, leading to motivation for compulsive symptoms. This hypothesis was investigated in an analogue population, using regression analyses controlling for depression and anxiety. Consistent with predictions, it was found that higher levels of DC and lower levels of SC were associated with higher levels of OCD-related beliefs and symptoms. While control cognitions were linked with the OCD-related beliefs of perfectionism and the over-estimation of threat, they did not relate to cognitions concerning the importance of/need to control thoughts. With respect to specific OCD-symptoms, control cognitions were most strongly related to contamination obsessions/washing compulsions. Implications for theory and treatment are discussed.

Adult attachment insecurities are associated with obsessive compulsive disorder

OBJECTIVES Obsessive compulsive disorder (OCD) is one of the most disabling and highly prevalent anxiety disorders (ADs). Current cognitive models of OCD implicate views about the self and world in the maintenance of the disorder. However, little research has focused on issues that may lead to vulnerability to such views. In particular, a persons attachment insecurities (attachment anxiety, avoidance) may be important risk factors increasing the likelihood of such non-adaptive perceptions (Doron & Kyrios, 2005). DESIGN Participants meeting criteria for OCD were compared with cohorts meeting criteria for other ADs and healthy controls on a range of measures including adult attachment, OC symptoms, cognitions, and mood. METHODS Diagnosis of the clinical groups was established using the Anxiety Disorders Interview Schedule for DSM-IV (Brown, Di Nardo, & Barlow, 1994). The clinical relevance of attachment insecurities was ascertained by comparing their prevalence in an OCD sample (N = 30), an ADs sample (N = 20), and a community sample (N = 32). RESULTS Attachment anxiety was significantly higher in individuals with OCD, even when controlling for depression. CONCLUSIONS Addressing attachment anxiety in individuals presenting with OCD may be important for enhancing therapeutic outcomes. However, findings are based on cross-sectional data that preclude conclusions relating to causal influence.

Emotion regulation as a transdiagnostic treatment construct across anxiety, depression, substance, eating and borderline personality disorders: A systematic review

A large body of research has implicated difficulties in emotion regulation as central to the development and maintenance of psychopathology. Emotion regulation has therefore been proposed as a transdiagnostic construct or an underlying mechanism in psychopathology. The transdiagnostic role of emotion regulation has yet to be systematically examined within the psychological treatment outcome literature. It can be proposed that if emotion regulation is indeed a transdiagnostic construct central to the maintenance of psychopathology, then changes in emotion regulation difficulties will occur after effective treatment and this will occur for different disorders. We conducted a systematic review, identifying 67 studies that measured changes in both emotion regulation and symptoms of psychopathology following a psychological intervention for anxiety, depression, substance use, eating pathology or borderline personality disorder. Results demonstrated that regardless of the intervention or disorder, both maladaptive emotion regulation strategy use and overall emotion dysregulation were found to significantly decrease following treatment in all but two studies. Parallel decreases were also found in symptoms of anxiety, depression, substance use, eating pathology and borderline personality disorder. These results contribute to the growing body of evidence supporting the conceptualization of emotion regulation as a transdiagnostic construct. The present study discusses the important implications of these findings for the development of unified treatments that target emotion regulation for individuals who present with multiple disorders.

Desire for control, sense of control and obsessive-compulsive checking: An extension to clinical samples

Research in non-clinical samples has suggested that control beliefs, specifically desire for control and sense of control, may play a role in Obsessive--Compulsive Disorder. The present study extends a previous research design to clinical participants [Moulding, R., Kyrios, M., & Doron, G. (2007). Obsessive-compulsive behaviours in specific situations: The relative influence of appraisals of control, responsibility and threat. Behaviour Research and Therapy, 45, 1693-1702]. In this study, clinical participants with OCD-checking symptoms (n=16), anxiety disorders (n=17) and community controls (n=27) were presented with four hypothetical scenarios. Using a manipulation paradigm, the relationship between control appraisals and other OCD-relevant constructs (threat, responsibility) was examined. As in the non-clinical study, desire for control was moderately affected by responsibility and threat manipulations, while sense of control was not affected by these manipulations. Individuals with OCD recorded higher desire for control and lower sense of control relative to community controls, and a higher desire for control than the anxiety group, suggesting some specificity to OCD. A possible interactive model of control, threat and responsibility is discussed.

We Do Not See Things as They Are, We See Them as We Are: A Multidimensional Worldview Model of Obsessive- Compulsive Disorder

Cognitive-behavioral models of obsessive-compulsive disorder (OCD) assign a central role to specific beliefs and coping strategies in the development, maintenance and exacerbation of obsessive-compulsive (OC) symptoms. These models also implicate perceptions of self and the world in the development and maintenance of OC phenomena (e.g., overestimation of threat, sociotropy, ambivalent or sensitive sense of self, looming vulnerability), although such self and world domains have not always been emphasized in recent research. Following recent recommendations (Doron & Kyrios, 2005), the present study undertook a multifaceted investigation of self and world perceptions in a nonclinical sample, using a coherent worldview framework (Janoff-Bulman, 1989, 1991). Beliefs regarding the self and the world were found to predict OC symptom severity over and above beliefs outlined in traditional cognitive-behavioral models of OCD. Self and world beliefs were also related to other OC-relevant beliefs. Implications of these findings for theory and treatment of OCD are discussed.

Fear of self and unacceptable thoughts in obsessive-compulsive disorder

UNLABELLED Cognitive-behavioural models have linked unacceptable or repugnant thoughts in obsessive-compulsive disorder (OCD) with vulnerable self-themes and fear-of-self concerns. To investigate this notion, Aardema and coworkers recently developed and validated the Fear of Self-Questionnaire (FSQ) in non-clinical samples, finding it had strong internal inconsistency, and good divergent and convergent validity, including strong relationships to obsessional symptoms and with other processes implicated in cognitive models of OCD (e.g., obsessive beliefs and inferential confusion). The current article describes two studies that aim to replicate and extend these findings in clinical OCD and non-clinical samples. Study 1 investigated the psychometric properties of an Italian translation of the FSQ in a non-clinical sample (n = 405). Results of confirmatory factor analysis supported the unidimensionality of the scale; the FSQ also showed very good internal consistency and temporal stability. Study 2 investigated the role of fear of self in OCD symptoms, and unacceptable thoughts and repugnant obsessions in particular, using a clinical OCD sample (n = 76). As expected, fear of self was a unique, major predictor of unacceptable thoughts independent of negative mood states and obsessive beliefs. Moreover, even when considered with obsessive beliefs, anxiety and depression, the feared self was the only unique predictor of obsessionality, providing support for the notion that self-themes could explain why some intrusions convert into obsessions, whereas others do not. Implications for current cognitive-behavioural models are discussed. Copyright

Emotional regulation, attachment to possessions and hoarding symptoms

This study aimed to test which particular facets of emotion regulation (ER) are most linked to symptoms of hoarding disorder, and whether beliefs about emotional attachment to possessions (EA) mediate this relationship. A non-clinical sample of 150 participants (108 females) completed questionnaires of emotional tolerance (distress tolerance, anxiety sensitivity, negative urgency - impulsivity when experiencing negative emotions), depressed mood, hoarding, and beliefs about emotional attachment to possessions. While all emotional tolerance measures related to hoarding, when considered together and controlling for depression and age, anxiety sensitivity and urgency were the significant predictors. Anxiety sensitivity was fully mediated, and urgency partially mediated, via beliefs regarding emotional attachment to possessions. These findings provide further support for (1) the importance of anxiety sensitivity and negative urgency for hoarding symptoms, and (2) the view that individuals with HD symptoms may rely on items for emotion regulation, leading to stronger beliefs that items are integral to emotional wellbeing.
