Dysfunctional Belief Domains Related to Obsessive-Compulsive Disorder: A Further Examination of their Dimensionality and Specificity

International consensus has been achieved on the existence of several dysfunctional beliefs underlying the development and/ or maintenance of the Obsessive-Compulsive Disorder (OCD). Nevertheless, questions such as the dimensionality of the belief domains and the existence of OCD-specific dysfunctional beliefs still remain inconclusive. The present paper addresses these topics through two different studies. Study 1: A series of confirmatory factor analyses (N = 573 non-clinical subjects) were carried out on the Obsessive Beliefs Spanish Inventory-Revised (OBSI-R), designed to assess dysfunctional beliefs hypothetically related to OCD. An eight-factor model emerged as the best factorial solution: responsibility, over-importance of thoughts, thought-action fusion-likelihood, thought action fusion-morality, importance of thought control, overestimation of threat, intolerance of uncertainty and perfectionism. Study 2: The OBSI-R and other symptom measures were administered to 75 OCD patients, 22 depressed patients, and 25 non-OCD anxious patients. Results indicated that, although OCD patients differed from their non-clinical counterparts on all of the OBSI-R subscales, no evidence of OCD-specificity emerged for any of the belief domains measured, as the OCD subjects did not differ from the other two clinical groups of patients.

Cognitive therapy for autogenous and reactive obsessions: Clinical and cognitive outcomes at post-treatment and 1-year follow-up

This study provides data about the differential effectiveness of cognitive therapy (CT) for obsessive-compulsive disorder (OCD) symptom presentation. Two OCD manifestations, autogenous and reactive, are considered. Seventy OCD patients started CT; 81.40% completed it and 72.85% were available 1 year later. Fifteen of the 57 treatment completers had autogenous obsessions, whereas 33 had reactive obsessions. Nine patients had both obsession modalities. Reactive patients were more severe, as they scored higher on thought suppression and on the dysfunctional beliefs of intolerance to uncertainty and perfectionism. Autogenous patients scored higher on the over-importance of thoughts beliefs. Although CT was effective in reducing OCD severity and the ascription to dysfunctional beliefs and neutralizing strategies in both the autogenous and the reactive patients, a significantly better outcome was observed for the autogenous patients, both at post-treatment (with 73.33% recovering versus 33.33% for reactives) and 1 year later.

Empirically Grounded Clinical Interventions: Cognitive Versus Behaviour Therapy in the Individual Treatment of Obsessive-Compulsive Disorder: Changes in Cognitions and Clinically Significant Outcomes at Post-Treatment and One-Year Follow-Up

Clinical significance analyses of controlled studies comparing Exposure and Response Prevention (ERP) and Cognitive Therapy (CT) in the treatment of Obsessive-Compulsive Disorder (OCD) are scarce. The objective of this study is to compare the clinical efficacy of ERP and CT for OCD patients, and the usefulness of each in changing dysfunctional beliefs and thought control strategies at post-treatment and at a one-year follow-up. The two treatments were delivered on the basis of a routine clinical practice in a public-mental health service. Thirty-three OCD patients were randomly assigned to ERP or CT, and 29 completed the treatments (13 in ERP and 16 in CT). The ERP applied was in vivo, gradual and therapist-guided. The CT was designed to challenge all the cognitive domains considered relevant for OCD, using cognitive techniques. The improvement and recovery rates (YBOCS) were slightly superior for CT than for ERP (ERP: 69.23% and 61.53%, respectively; CT: 81.25% and 68.75%, respectively). These therapeutic outcomes were maintained after the two treatments: at the one-year follow-up, 53.85% of the treated patients remained free of symptoms in ERP, and 65.5% in CT. Finally, the two treatments were equally effective in modifying dysfunctional beliefs, and the outcomes at the end of the treatments were maintained, or even increased, one year later.

Group Versus Individual Cognitive Treatment for Obsessive-Compulsive Disorder: Changes in Severity at Post-Treatment and One-Year Follow-up

BACKGROUND Very few studies have compared the efficacy of individual and group cognitive behaviour therapy (CBT) for the treatment of Obsessive-Compulsive Disorder (OCD) by taking into consideration the change in OCD severity in both the short and long term. AIMS To conduct an open trial of individual versus group CBT for OCD, comparing the clinical and statistically significant changes in severity both at post-treatment and one year later. METHOD Forty-two OCD subjects were assigned to individual (n = 18) or group CBT (n = 24, in four groups). Sixteen and 22 subjects completed the treatment in the individual and group conditions, respectively. The Yale-Brown Obsessive Compulsive Scale was recorded at pre-treatment, post-treatment and at the one-year follow-up. RESULTS At the end of treatment, the clinically significant change was comparable for the two treatment conditions and remained stable at the one-year follow-up. Of the 16 participants who completed the individual CBT treatment, 68.75% were classified as recovered at post-treatment, compared to 40.9% of those receiving group CBT. At follow-up the rate of recovery decreased to 62.5% in individual CBT and to 31.8% in group CBT. CONCLUSIONS Group CBT is effective in decreasing OCD severity. The post-treatment changes were maintained one year later. Nevertheless, these changes were higher in the individual delivery of CBT.

Group versus individual cognitive treatment for Obsessive-Compulsive Disorder: Changes in non-OCD symptoms and cognitions at post-treatment and one-year follow-up

Current cognitive approaches postulate that obsessions and compulsions are caused and/or maintained by misinterpretations about their meaning. This assumption has led to the development of cognitive therapeutic (CT) procedures designed to challenge the dysfunctional appraisals and beliefs patients have about their obsessions. Nonetheless, few studies have compared the efficacy of individual and group CT in changing the dysfunctional cognitions that hypothetically underlie Obsessive-Compulsive Disorder (OCD). In this study, 44 OCD patients were assigned to individual (n=18) or group (n=24) CT. Sixteen completed the individual CT, and 22 completed the group CT. The effects of the two CT conditions on depression and worry tendencies were comparable. Individual treatment was more effective than group treatment in decreasing scores on dysfunctional beliefs (responsibility, overestimation of threat, and intolerance to uncertainty) and the use of suppression as a thought control strategy. The post-treatment changes were maintained one year later. The correlations between symptom improvement (OCD severity change) and belief changes were moderate: in the individual treatment the greatest associations were with beliefs about thoughts (importance and control), whereas in the group treatment the greatest associations were with beliefs related to anxiety in general (threat overestimation and intolerance to uncertainty).

Sucesos vitales estresantes en el inicio del trastorno obsesivo-compulsivo: un estudio retrospectivo

espanolEl objetivo fue examinar la importancia de experimentar un suceso vital estresante(SVE) para el inicio de un trastorno obsesivo-compulsivo (TOC). Se entrevistaron a 85 pacientes con TOC para evaluar la ocurrencia y caracteristicas de SVEs previos al inicio del trastorno. El 70,6% senalo al menos un SVE. De ellos, el 66,1% valoro el suceso como negativo, el 80,7% como muy importante y el 79,3% como muy influyente en su trastorno. Los sintomas depresivos, una menor edad al inicio del trastorno y las obsesiones del tipo reactivo se asociaron a diferentes aspectos del SVE. La influencia del SVE en el trastorno se asocio a una valoracion negativa del suceso. La experimentacion de un SVE no se asocio a la respuesta terapeutica. EnglishThe objective was to analyze the importance of experiencing a stressful life event(SLE) associated with the onset of the obsessive-compulsive disorder (OCD). A group of 85 OCD patients were interviewed to assess the occurrence and characteristics of SLEs previous to the onset of the disorder. Up to 70.6% informed at least one SLE. The 66.1% of them appraised the event as negative, the 80.7% as very important, and the 79.3% as very influential in their disorder. Comorbid depressive symptoms, a lower age at the onset, and the reactive subtype obsessions were associated with the different SLE’s variables. The influence of the SLE on the disorder was associated with a negative appraisal. The SLE was not related to the therapeutical response.
