Pathological gambling has been proposed to belong to the obsessive-compulsive spectrum of disorders. Disorders on this spectrum are thought to share similar clinical features, neurobiology, and responses to treatment as Obsessive-Compulsive Disorder. A total of 18 studies were included in a meta-analysis to assess the strength of the association between these disorders. A strong relationship (effect size = 1. 01) was found between pathological gambling and obsessive-compulsive traits. A weak relationship was found between pathological gambling and Obsessive-Compulsive Disorder (.07) and Obsessive-Compulsive Personality Disorder (effect size = .23). These results suggest pathological gambling and Obsessive-Compulsive Disorder are distinct disorders. However, pathological gamblers do appear to show high rates of obsessive-compulsive traits relative to controls. These findings are only moderately supportive of the inclusion of pathological gambling within the obsessive-compulsive spectrum of conditions.

Compulsive Disorder

IntroductionCognitive–behavioural therapy (CBT) with exposure and response prevention is the recommended standard for the treatment of obsessive–compulsive disorder (OCD). However, a high proportion of patients refuse this treatment, do not respond or relapse shortly after treatment. Growing evidence suggests that mindfulness-based and acceptance-based programmes (MABPs) are an effective option for the treatment of OCD. This systematic review and meta-analysis will examine the effectiveness of MABPs in treating OCD. We also aimed to explore potential moderators of the programmes’ effectiveness.Methods and analysisWe will systematically search MEDLINE, Embase, PsycINFO, PSYINDEX, Web of Science, CINAHL and Cochrane Register of Controlled Trials (no language restrictions) for studies that evaluate the effect of MABPs on patients with OCD. We will conduct backward and forward citation searches of included studies and relevant reviews and contact corresponding authors. The primary outcome will be pre-post intervention change in symptom severity. A secondary outcome will be change in depressive symptoms. Two reviewers will independently screen the records, extract the data and rate the methodological quality of the studies. We will include both controlled and uncontrolled trials. Randomised controlled trials will be meta-analysed, separately assessing between-group effects. A second meta-analysis will assess the within-group effect of all eligible studies. We will explore moderators and sources of heterogeneity such as the specific programme, study design, changes in depressive symptoms, hours of guided treatment, control condition and prior therapy (eg, CBT) using metaregression and subgroup analyses. We will perform sensitivity analyses using follow-up data. A narrative synthesis will also be pursued. We will use the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to assess the quality of the evidence.Ethics and disseminationEthical approval is not required. Results will be published in peer-reviewed journals and presented at international conferences.

BackgroundSpecific cortico-striato-thalamic circuits are hypothesised to mediate the symptoms of obsessive–compulsive disorder (OCD), but structural neuroimaging studies have been inconsistent.AimsTo conduct a meta-analysis of published and unpublished voxel-based morphometry studies in OCD.MethodTwelve data-sets comprising 401 people with OCD and 376 healthy controls met inclusion criteria. A new improved voxel-based meta-analytic method, signed differential mapping (SDM), was developed to examine regions of increased and decreased grey matter volume in the OCD group v. control group.ResultsNo between-group differences were found in global grey matter volumes. People with OCD had increased regional grey matter volumes in bilateral lenticular nuclei, extending to the caudate nuclei, as well as decreased volumes in bilateral dorsal medial frontal/anterior cingulate gyri. A descriptive analysis of quartiles, a sensitivity analysis as well as analyses of subgroups further confirmed these findings. Meta-regression analyses showed that studies that included individuals with more severe OCD were significantly more likely to report increased grey matter volumes in the basal ganglia. No effect of current antidepressant treatment was observed.ConclusionsThe results support a dorsal prefrontal–striatal model of the disorder and raise the question of whether functional alterations in other brain regions commonly associated with OCD, such as the orbitofrontal cortex, may reflect secondary compensatory strategies. Whether the reported differences between participants with OCD and controls precede the onset of the symptoms and whether they are specific to OCD remains to be established.
