BackgroundThere is an urgent need for an effective psychological treatment for patients with obsessive compulsive disorder (OCD) with poor insight, since this disorder is associated with severe suffering and a low quality of life. The inference based approach (IBA), a new psychotherapy for OCD specifically targets insight in OCD. In a randomized controlled multicentre trial, the effectiveness of IBA was compared to the effectiveness of CBT for treating patients with OCD with poor insight. In this study, 24 sessions of IBA were tested versus 24 sessions of CBT. Ninety patients with a main diagnosis of OCD with poor insight according to the DSM-IV criteria participated in the study. The primary outcome was reduction of the obsessive-compulsive symptoms.ResultsIn both conditions, a significant OCD symptom reduction was reached, but no condition effects were established. Post hoc, in a small subgroup of patients with the worst insight (n = 23), it was found that the patients treated with the IBA reached a significantly higher OCD symptom reduction than patients treated with CBT [estimated marginal mean = –7.77, t(219.45) = –2.4, P = 0.017]. Of patients treated with IBA, 41.9% were responder and 20.9% completely recovered. Of the patients treated with CBT, 42.6% were responder and 12.8% recovered.ConclusionPatients with OCD with poor insight improve significantly after psychological treatment. The results of this study suggest that both CBT and the IBA are effective treatments for OCD with poor insight. The IBA might be more promising than CBT for patients with more extreme poor insight.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Pre Treatment

Forty-nine obsessive-compulsive ritualizers had clomipramine and live exposure in a randomized controlled design. The effect on outcome of pre-treatment expectations from psychological and from drug treatment and of subsequent compliance with exposure instructions was studied. Exposure instructions led to greater pre-treatment expectations than did anti-exposure instructions, but this did not affect outcome, suggesting that the effect of exposure was not due to expectation. Initially, more ill patients expected more from drug but improved less. Compliance with psychological treatment did not predict better improvement, but most patients were fairly compliant.

IntroductionUp to 50% of patients with OCD have failed to respond in SSRI trials, so looking for pharmacological alternatives in treatment of obsessive compulsive disorder (OCD) seems necessary.ObjectivesSurveying duloxetine augmentation in treatment of resistant OCD.AimsStudy the effects of serotonin-norepinephrine enhancers for treatment of OCD.MethodsThis augmentation trial was designed as an 8-week randomized controlled, double blind study. Forty-six patients suffering from OCD who had failed to respond to at least 12 weeks of treatment with a selective serotonin reuptake inhibitor (fluoxetine, citalopram or fluvoxamine) were randomly allocated to receive duloxetine or sertraline plus their current anti OCD treatment. Yale-Brown Obsessive Compulsive Scale (Y-BOCS) was the primary outcome measure.ResultsForty-six patients (24 of 30 in duloxetine group and 22 of 27 in sertraline group) completed the trial. Both groups showed improvement over the 8-week study period (mean Y-BOCS total score at week 8 as compared with baseline: P < 0.001 and P < 0.001) without significant difference (P = 0.861). Those receiving duloxetine plus their initial medications experienced a mean decrease of 33.0% in Y-BOCS score and the patients with sertraline added to their initial medication experienced a mean decrease of 34.5% in Y-BOCS.ConclusionsOur double blind controlled clinical trial showed duloxetine to be as effective as sertraline in reducing obsessive and compulsive symptoms in resistant OCD patients. However, it needs to be noted that our study is preliminary and larger double blind placebo controlled studies are necessary to confirm the results.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract The differential diagnosis of obsessive–compulsive disorder (OCD) and schizophrenia-spectrum disorders can be difficult. In the current diagnostic criteria, basic concepts such as obsession and delusion overlap. This study examined lifetime schizophrenia-spectrum psychopathology, including subtle schizotypal symptomatology and subjective anomalies such as self-disorders, in a sample diagnosed with OCD in a specialized setting. The study also examined the differential diagnostic potential of the classic psychopathological notions of true obsession (‘with resistance’) and pseudo-obsession. The study involved 42 outpatients diagnosed with OCD at two clinics specialized in the treatment of OCD. The patients underwent semi-structured, narrative interviews assessing a comprehensive battery of psychopathological instruments. The final lifetime research-diagnosis was based on a consensus between a senior clinical psychiatrist and an experienced research clinician. The study found that 29% of the patients fulfilled criteria of schizophrenia or another non-affective psychosis as main, lifetime DSM-5 research-diagnosis. Another 33% received a research-diagnosis of schizotypal personality disorder, 10% a research-diagnosis of major depression and 29% a main research-diagnosis of OCD. Self-disorders aggregated in the schizophrenia-spectrum groups. True obsessions had a specificity of 93% and a sensitivity of 58% for a main diagnosis of OCD. In conclusion, a high proportion of clinically diagnosed OCD patients fulfilled diagnostic criteria of a schizophrenia-spectrum disorder. The conspicuous obsessive–compulsive symptomatology may have resulted in a disregard of psychotic symptoms and other psychopathology. Furthermore, the differentiation of obsessions from related psychopathological phenomena is insufficient and a conceptual and empirical effort in this domain is required in the future.
