Specificity of belief domains in OCD: validation of the French version of the Obsessive Beliefs Questionnaire and a comparison across samples.

This paper assesses the psychometric properties of the French version of the Obsessive Beliefs Questionnaire (OBQ-44) and investigates whether the questionnaire discriminates between obsessive-compulsive disorder (OCD), anxious control (AC), and non-clinical control (NCC) participants. A confirmatory factor analysis suggested a poor fit of the model. An exploratory factor analysis replicated the original factor structure. The subscales were moderately intercorrelated and highly correlated with the total score. There was partial support for convergent/divergent validity of the OBQ-44. In analyses of variance comparing the three samples, the participants in the OCD sample scored significantly higher than the participants in the AC and NCC samples on all of the OBQ-44 scores. In analyses of covariance comparing the OCD and NCC samples while controlling for general distress and age, the participants with OCD scored significantly higher than the NCC participants on all of the OBQ-44 scores. Implications of the current study are discussed.

[The implementation process of a new model of intensive rehabilitation in a hospital setting: the development of an innovative practice within the context of integration of settings, services and treatment models]. / Le processus d'implantation d'un nouveau modèle de réhabilitation intensive en milieu hospitalier: le développement d'une pratique novatrice dans le contexte de l'intégration des milieux, des services, et des modèles de soins.

This article describes the process of implementation of an internal intensive rehabilitation program at Douglas hospital for people with severe mental disorders. A discussion of contemporary paradigms of rehabilitation implies the integration of biological and psychosocial perspectives in the characterization and treatment of the pathology. The discussion of the reorganization of the entire rehabilitation services of the Program for severe mental disorders leads to specifying the organizational and regional context of the implementation. The axes of implementation in priority are the following : analysis of needs, training, reorganization of work and modification of the setting of care. These activities are implemented in reference to scientific developments that are empirically relevant and assessed regularly. Future challenges include the pursuit of integration of treatment models, of settings and services within the context of the hierarchy of mental health care in Québec.

Treating delusional disorder: a comparison of cognitive-behavioural therapy and attention placebo control.

OBJECTIVE: Cognitive-behavioural therapy (CBT) has proved effective in treating delusions, both in schizophrenia and delusional disorder (DD). Clinical trials of DD have mostly compared CBT with either treatment as usual, no treatment, or a wait-list control. This current study aimed to assess patients with DD who received CBT, compared with an attention placebo control (APC) group. METHOD: Twenty-four individuals with DD were randomly allocated into either CBT or APC groups for a 24-week treatment period. Patients were diagnosed on the basis of structured clinical interviews for mental disorders and the Maudsley Assessment of Delusion Schedule (MADS). RESULTS: Completers in both groups (n = 11 for CBT; n = 6 for APC) showed clinical improvement on the MADS dimensions of Strength of Conviction, Insight, Preoccupation, Systematization, Affect Relating to Belief, Belief Maintenance Factors, and Idiosyncrasy of Belief. CONCLUSION: When compared with APC, CBT produced more impact on the MADS dimensions for Affect Relating to Belief, Strength of Conviction, and Positive Actions on Beliefs.
