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 (READ) was completed by 307 Norwegian high school students (M = 16.4 years) along with the Depression Anxiety Stress Scales, and the Obsessive-Compulsive Inventory-Revised. RESULTS Higher resilience scores predicted lower scores on levels of depression, anxiety, stress and obsessive-compulsive symptoms after controlling for age and gender. CONCLUSION This study provides further evidence that it may be fruitful for clinicians and researchers to attend to resilience factors in relation to psychological symptoms among older adolescents.

BackgroundObsessive-compulsive disorder (OCD) in patients with psychotic disorders has been reported to be a frequent co-morbid disorder in patients with psychotic disorders. The aim of the study determine the prevalence of OCD in first-episode psychosis and the relationship with clinical characteristics.MethodsFirst-episode psychosis patients (N = 246) consecutively admitted to a comprehensive early psychosis program were assessed for OCD with the Structured Clinical Interview for DSM-IV. Symptom assessment measures were the Positive and Negative Syndrome Scale, Global Assessment of Functioning, and the Clinician Rating Scale.ResultsTwenty-six patients (10.6%) fulfilled the criteria for OCD. Patients with comorbid OCD were younger, had more depressive symptoms and a higher rate of suicidal plans or attempts at index point compared to patients without OCD. The two groups did not differ with respect to other demographic variables or severity of psychotic symptoms.ConclusionOCD is a significant comorbid disorder in patients with first-episode psychosis. Since treatment procedures are different, systematic screening for OCD is warranted.

BACKGROUND Obsessive-compulsive disorder (OCD) has been observed in a substantial proportion of patients with schizophrenia. Although cognitive-behavioural therapy (CBT) is well documented for OCD, few case studies are available regarding CBT for comorbid OCD in schizophrenia. AIMS The study aims to present a case study to augment the limited knowledge concerning CBT treatment for OCD in patients with schizophrenia. METHOD The research adopted a case study approach, with a baseline condition and repeated assessments during the 3-week treatment and 6-month follow-up period. RESULTS The treatment was successful and the patient achieved clinical significant change in OCD symptoms. The patient had a reduction on the Y-BOCS from 24 to 5 (79%) and from 38 to 10 (73%) on the OCI-R from before treatment to 6 months follow-up. He did not fulfil the criteria for an OCD diagnosis at the end of the 3-week treatment period, or the follow-up at 3- and 6 months. CONCLUSIONS The results strengthen the impressions given by previous case studies suggesting that CBT may be a promising treatment for OCD in patients with schizophrenia.

In this study, we examined how jealousy responses in men and women were affected by 2D:4D digit ratio, a correlate of prenatal testosterone exposure, and actual infidelity experiences using the forced-choice paradigm. Extending the previous literature on responses to infidelity, we examined whether specific types of infidelity and whether active manipulation of memories of actual infidelity experiences affected jealousy responses. We were able to replicate the predicted sex differences in jealousy responses in a sample of heterosexual Norwegian students with committed relationship experiences (N = 480). Further, we found that 2D:4D ratio was negatively associated with sexual jealousy, but as predicted, this effect was fully accounted for by sex of respondent. Men reported more sexual jealousy than women regardless of experiencing actual infidelity and regardless of infidelity type. Actual infidelity experiences produced more pronounced sex-typical differences when memories of these were activated through question order manipulation. Suggestions for future studies on jealousy responses to infidelity experiences are made.

The Bergen 4-day concentrated exposure treatment (cET) for obsessive-compulsive disorder (OCD) has proven highly acceptable; with practically no drop-out and a 6 month remission rate of nearly 70%. The aim of the present study was to evaluate long term gains of the approach, and to compare the results to findings from our recent meta-analysis. Sixty-nine of 95 patients consecutively referred to an outpatient clinic in the specialist health care, were offered the Bergen 4-day treatment. Among the 65 who initiated treatment, 60.0% were classified with “severe” to “extreme” OCD. None of the patients dropped-out during treatment. Independent Yale-Brown Obsessive-Compulsive Scale interviews were conducted post-treatment, and at 3- and 12-month follow-up. Using the international consensus criteria, 83.1% responded to treatment at 12-month follow-up, and 67.7% of patients were classified as recovered. Significant changes were also seen in depression, as measured by Patient Health Questionnaire-9, and in generalized anxiety, as measured by Generalized Anxiety Disorder-7 scale. A total of 89% of the patients rated the treatment as very good and 100% would recommend the treatment to a friend. Compared to results in a recent meta-analysis, the Bergen 4-day treatment is favorable in respect to attrition, response and 12-month recovery. In sum the Bergen 4-day treatment is a feasible way to deliver treatment for OCD, and the effects are stable at 12-month follow-up. Implications for dissemination are discussed.

ABSTRACT There are few long-term follow-up studies on psychological treatment of anxiety disorders carried out in clinical mental health settings, so called effectiveness studies. The present paper presents a four year follow-up of patients with obsessive-compulsive disorder treated by the Bergen 4-day treatment (B4DT), a concentrated form of exposure and response prevention (ERP). A total of 77 obsessive–compulsive disorder (OCD) patients received treatment during four consecutive days and were assessed with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) pre, post, and at follow-ups after 3 and 6 months, and 4 years post-treatment. The Y-BOCS mean score changed from 25.9 at pre- to 10.0 post-treatment and 9.9 at long-term follow-up. The proportion fulfilling the strict international consensus criteria for remission was 73% at post-treatment and 69% at follow-up. When taking declining rate, attrition rate, remission, relapse, and further improvement during the follow-up period into account, 72% were recovered on a long-term basis. A comparison with previously published effectiveness studies of ERP indicated that the 4-day treatment yielded significantly higher proportions of remission at post-treatment and recovery at follow-up, as well as within-group effect size on the Y-BOCS. The implications of these results are discussed.

A premise for cognitive behavioral therapy (CBT) for obsessive-compulsive disorder (OCD) is that appraisal of obsessions maintains OCD symptoms whereas obsessive content is less important. The main aim of this study was therefore to explore this notion using the autogenous and reactive classification of obsessive content and by assessing changes in appraisals and symptoms following CBT for OCD. More specifically, the study investigates whether recovery from OCD is associated with changes in appraisal and explores how thought content relates to appraisal and symptoms both before and CBT. Data from 156 adults with OCD completing CBT for OCD were analyzed. Changes in appraisals were related to improvement in OCD symptoms. Slightly more participants reported reactive intrusions (47%) than autogenous (29%), but combinations of the two were common (24%). These classifications of thought content were not related to levels of appraisal or change in symptoms, with the exception of patients with autogenous thoughts who appraised their intrusions as more important than others. OCD is heterogeneous regarding thought content and strength of appraisals but can be quite homogeneous in terms of CBT treatment response. Also, and in line with cognitive theory, recovery from OCD is associated with changes in appraisals.

The current article reports on the findings from a pilot treatment study on panic disorder (PD) with or without agoraphobia. Consecutively referred patients were included and treated with the Bergen 4-day treatment format. Twenty-nine patients were included, primarily from unsuccessful treatment courses in the Norwegian specialist mental health care system, either ongoing or previously. Prior to treatment, only 34% were able to work but at 3-month follow-up 93% were able to do so. The proportion achieving reliable change on the panic severity measure was 76% post-treatment and 90% at follow-up. The remission rate was 72% at both assessments. These effects are significantly higher than those reported for six standard CBT studies in the literature using the same primary outcome measure (Panic Disorder Severity Scale). It is concluded that the Bergen 4-day treatment is a promising treatment approach for PD, and a randomized controlled trial is warranted.

BackgroundOslo University Hospital, Norway, had by autumn 2016, accumulated a waiting list of 101 patients with obsessive-compulsive disorder (OCD) who had a legal right to receive treatment by a specialized OCD team. In this challenging situation, the Bergen OCD-team suggested to solve the problem by offering all patients an option for the rapid Bergen 4-day treatment (B4DT). The B4DT is an individual treatment delivered during four consecutive days in a group of six patients with the same number of therapists. The approach has previously shown a post-treatment response rate of 90% and a 3-month remission rate of 70%.MethodsNinety-seven of the wait-list patients were available for the scheduled time slots, and 90 received the 4-day format during 8 days (45 patients each week). The therapists were recruited from 22 different specialized OCD-teams from all over Norway, and 44 (68%) had not previously delivered the 4-day format.ResultsPost-treatment; 91.1% of the patients were classified as responders, and 72.2% were in remission. At 3-month follow-up; 84.4 were classified as responders and the remission rate was 67.7%. Oslo University Hospital now offers the 4-day treatment as standard treatment for OCD.ConclusionsWe conclude that the B4DT is an acceptable and potentially effective OCD-treatment.
