The obsessive-compulsive inventory: Development and validation of a short version

This article reports on the development of a revised version of the Obsessive-Compulsive Inventory (OCI; E. B. Foa, M. J. Kozak, P. Salkovskis, M. E. Coles, & N. Amir, 1998), a psychometrically sound, theoretically driven, self-report measure. The revised OCI (OCI-R) improves on the parent version in 3 ways: It eliminates the redundant frequency scale, simplifies the scoring of the subscales, and reduces overlap across subscales. The reliability and validity of the OCI-R were examined in 215 patients with obsessive-compulsive disorder (OCD), 243 patients with other anxiety disorders, and 677 nonanxious individuals. The OCI-R, which contains 18 items and 6 subscales, has retained excellent psychometric properties. The OCI-R and its subscales differentiated well between individuals with and without OCD. Receiver operating characteristic (ROC) analyses demonstrated the usefulness of the OCI-R as a diagnostic tool for screening patients with OCD, utilizing empirically derived cutscores.

Obsessional-compulsive problems: A cognitive-behavioural analysis

Abstract Cognitive-behavioural approaches have made no impact on research and treatment in obsessional-compulsive disorder, despite the obvious link between thinking and psychopathology that characterizes this disorder. A close examination of cognitive and behavioural models leads to the suggestion that intrusive thoughts are best regarded as cognitive stimuli rather than responses. Cognitive responses (negative automatic thoughts) to these stimuli are typically linked to beliefs concerning responsibility or blame for harm to self or others. A cognitive-behavioural model based on this view is outlined and illustrated by clinical material derived from a case series. The model is used to explain a wide range of phenomena observed clinically, and a number of specific predictions are made. Implications for cognitive approaches to therapy are discussed.

Understanding and treating obsessive—compulsive disorder

The development of behaviour therapy for OCD and its evolution into cognitive behaviour therapy is described, highlighting the importance of a crucial series of experiments conducted by Rachman and colleagues in the mid-1970s. More recently, developments in cognitive theory suggest that the key to understanding obsessional problems lies in the way in which intrusive thoughts, images, impulses and doubts are interpreted. The important negative interpretations usually concern the idea that the persons action (or choice not to act) can result in harm to oneself or others. This responsibility interpretation has several consequences (such as motivating neutralising behaviour and other counter-productive strategies, increasing selective attention, increased negative mood); these serve to maintain the negative beliefs and therefore the obsessive-compulsive problem. Both general and specific aspects of cognitive-behavioural treatment are described. A number of treatment strategies which are specific to obsessional problems are described in clinical detail.

The Importance of Behaviour in the Maintenance of Anxiety and Panic: A Cognitive Account

The theoretical and empirical basis of commonly accepted propositions concerning the role of behaviour in the practice of behavioural psychotherapy for anxiety problems is considered. A number of problems are identified, and an alternative, more explicitly cognitive hypothesis is described. According to this cognitive account, there is both a close relationship and specific interactions between “threat cognitions” and “ safety seeking behaviour ”. For any individual, safety seeking behaviour arises out of, and is logically linked to, the perception of serious threat. Such behaviour may be anticipatory (avoidant) or consequent (escape). Because safety seeking behaviour is perceived to be preventative, and focused on especially negative consequences (e.g. death, illness, humiliation), spontaneous disconfirmation of threat is made particularly unlikely by such safety seeking behaviours. By preventing disconfirmation of threat-related cognitions, safety seeking behaviour may be a crucial factor in the maintenance of anxiety disorders. The implications of this view for the understanding and treatment of anxiety disorders are discussed.

Abnormal and normal obsessions—A replication

Abstract A replication of previous work on the incidence and characteristics of intrusive cognitions in non-clinical populations was carried out. The results closely reflected those obtained previously, and further relationships between variables were found. The importance of distinguishing between- and within- S data is stressed.

Social phobia: The role of in-situation safety behaviors in maintaining anxiety and negative beliefs

One of the puzzles surrounding social phobia is that patients with this problem are often exposed to phobic situations without showing a marked reduction in their fears. It is possible that individuals with social phobia engage in behaviors in the feared situation that are intended to avert feared catastrophes but that also prevent disconfirmation of their fears. This hypothesis was tested in a single case series of eight socially phobic patients. All patients received one session of exposure alone and one session of exposure plus decrease in “safety” behaviors in a counterbalanced within-subject design. Exposure plus decreased safety behaviors was significantly better than exposure alone in reducing within-situation anxiety and belief in the feared catastrophe. Other factors that may moderate exposure effects are also discussed.

Responsibility attitudes and interpretations are characteristic of obsessive compulsive disorder.

The cognitive-behavioural theory of Obsessive Compulsive Disorder (OCD) proposes that a key factor influencing obsessional behaviour is the way in which the intrusive cognitions are interpreted. The present paper reports an investigation of links between clinical symptoms (of anxiety, depression and obsessionality) and responsibility beliefs. These beliefs include not only measures of general responsibility attitudes (assumptions) but also more specific responsibility appraisals consequent on intrusive cognitions. The characteristics of two new questionnaires specifically designed to measure these beliefs were assessed in patients suffering from Obsessive Compulsive Disorder, in patients suffering from other anxiety disorders and in non-clinical controls. The scales measuring negative beliefs about responsibility were found to have good reliability and internal consistency. Comparisons between criterion groups indicate considerable specificity for both assumptions and appraisals with respect to OCD. There was also good evidence of specificity in the association between responsibility cognitions and obsessional symptoms across groups, and that this association was not a consequence of links with anxiety or depressive symptoms. Although the two measures were correlated, they each made unique contributions to the prediction of obsessional symptoms. Overall, the results are consistent with the hypothesis that responsibility beliefs are important in the experience of obsessional problems.

Psychometric validation of the Obsessive Beliefs Questionnaire and the Interpretation of Intrusions Inventory: Part I

This article reports on the validation of the Obsessive Beliefs Questionnaire (OBQ) and Interpretations of Intrusions Inventory (III) developed by the Obsessive Compulsive Cognitions Working Group (OCCWG) to assess the primary beliefs and appraisals considered critical to the pathogenesis of obsessions. A battery of questionnaires that assessed symptoms of anxiety, depression, obsessive-compulsive symptoms and worry was administered to 248 outpatients with a DSM-IV diagnosis of Obsessive-Compulsive Disorder (OCD), 105 non-obsessional anxious patients, 87 non-clinical adults from the community, and 291 undergraduate students. Tests of internal consistency and test-retest reliability indicated that the OBQ and III assessed stable aspects of OC-related thinking. Between-group differences and correlations with existing measures of OC symptoms indicated that the OBQ and III assess core cognitive features of obsessionality. However, the various subscales of the OBQ and III are highly correlated, and both measures evidenced low discriminant validity. The findings are discussed in terms of the relevance and specificity of cognitive constructs like responsibility, control and importance of thoughts, overestimated threat, tolerance of uncertainty and perfectionism for OCD.

Invited essay∗Hypochondriasis☆

Hypochondriasis and other syndromes in which health anxiety is prominent are frequently seen in clinical practice and often pose problems of management. In contrast with other anxiety problems, the conceptualization and treatment of health anxiety has developed very little in recent years. Behavioural approaches to treatment have only recently been applied. In the present paper, current theoretical models are critically evaluated and a cognitive-behavioural approach is proposed to account for the development and maintenance of hypochondriacal problems. Principles of cognitive-behavioural treatment based on this approach are outlined, together with some suggestions for research.

Mind the gap: Improving the dissemination of CBT.

Empirically supported psychological treatments have been developed for a range of psychiatric disorders but there is evidence that patients are not receiving them in routine clinical care. Furthermore, even when patients do receive these treatments there is evidence that they are often not well delivered. The aim of this paper is to identify the barriers to the dissemination of evidence-based psychological treatments and then propose ways of overcoming them, hence potentially bridging the gap between research findings and clinical practice.
