The aim of the study was to investigate whether inexperienced student therapists could successfully learn exposure and response prevention for obsessive-compulsive disorder. Twenty out of 21 outpatients completed treatment as delivered by ten psychology students. A total of 60 hours group supervision and approximately 30 hours with individual supervision(More)
Predictors of improvement in obsessive-compulsive symptoms (Y-BOCS) in a randomized clinical trial with adult obsessive-compulsive disorder outpatients were examined. Results of multiple regression analyses revealed that a positive helping alliance was significantly predictive of posttreatment Y-BOCS. Treatment expectancy and high motivation to change were(More)
The aim of the current study was to further investigate the role of metacognitive beliefs implicated in Wells' (1997) model of obsessive-compulsive disorder (OCD). The metacognitive domains of thought-fusion beliefs and beliefs about rituals were positively correlated with obsessive-compulsive symptoms in a community control sample (N=269) and in an OCD(More)
Most 3-D magnetic particle imaging (MPI) scanners currently use permanent magnets to create the strong gradient field required for high resolution MPI. However, using permanent magnets limits the field of view (FOV) due to the large amount of energy required to move the field free point (FFP) from the center of the scanner. To address this issue, an(More)
The aims of this study were to test the psychometric properties of the Norwegian version of the Obsessive-Compulsive Inventory-Revised (OCI-R). The study included a student/community control sample (N = 1167) and a clinical sample (N = 72) with a diagnosis of obsessive-compulsive disorder (OCD). The results indicated a good fit for the six-factor structure(More)
OBJECTIVE Mental health problems affect approximately 20% of adolescents. Traditionally, the principal focus has been on vulnerability and risk factors and less on protective factors. The study, therefore, explores the relation between frequent psychiatric symptoms and resilience factors among older adolescents. METHOD The Resilience Scale for Adolescents(More)
While magnetic particle imaging (MPI) constitutes a novel biomedical imaging technique for tracking superparamagnetic nanoparticles in vivo, unlike magnetic resonance imaging (MRI), it cannot provide anatomical background information. Until now these two modalities have been performed in separate scanners and image co-registration has been hampered by the(More)
Current simulations of the signal in magnetic particle imaging (MPI) are either based on the Langevin function or on directly measuring the system function. The former completely ignores the influence of finite relaxation times of magnetic particles, and the latter requires time-consuming reference scans with an existing MPI scanner. Therefore, the(More)
This is the first study that explores whether early maladaptive schemas are related to treatment outcome for patients with obsessive-compulsive disorder (OCD). The sample consisted of 88 outpatients with a diagnosis of OCD who completed exposure and response prevention treatment. The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), the Beck Depression(More)
