  Childhood trauma (CT) is a known risk factor for major depressive disorder (MDD), yet its implications for treatment selection remain unclear. This exploratory randomized controlled trial (N = 100) compared short-term psychodynamic psychotherapy (STPP) and cognitive behavioral therapy (CBT) in adults with MDD treated in outpatient clinics. CT was assessed with the Childhood Trauma Questionnaire–Short Form (CTQ-SF), and depressive symptoms were measured using the Beck Depression Inventory-II (BDI-II) and the Hamilton Depression Rating Scale (HDRS) at baseline and after 28 weeks of therapy. Linear mixed-model analyses showed that CT was associated with higher depression severity at the start of treatment. No significant predictive effects of CT were found for treatment outcome or for moderation of the comparative effectiveness of CBT and STPP. Emotional abuse was initially associated with greater improvement in STPP compared to CBT on the HDRS, but the effect did not remain significant after correction for multiple testing. These findings suggest that both CBT and STPP are suitable options for patients with MDD and a history of CT.

  Background More studies with low risk of bias on the effectiveness of cognitive behavioral therapy (CBT) and short-term psychodynamic psychotherapy (STPP) for major depressive disorder (MDD) are needed. This study compares the outcome of CBT and STPP and examines the improvements in each treatment, focusing on effect sizes, reliable change, dropout rates, and remission rates, using broad inclusion criteria (e.g. participants using antidepressants or with strong suicidal ideation). Methods One hundred patients were randomly allocated to CBT or STPP. All patients were offered either 16 weekly sessions followed by 3 monthly booster sessions in CBT, or 28 weekly sessions in STPP. Primary outcome measures were Hamilton Depression Rating Scale (HDRS) and Beck’s Depression Inventory-II (BDI-II). Secondary outcome measures were Work and Social Adjustment Scale (WSAS), Generalized Anxiety Disorder-7 (GAD-7), Global Assessment of Functioning (GAF) and Short Form Health Survey-12 (SF-12). Results No significant differences in outcomes were found between the two treatment groups on any of the measures. The within-group effects were large (> 0.8) for the primary outcome measures and moderate to large for the secondary outcome measures. According to the reliable change index (RCI), 79% of patients reliably improved on HDRS and 76% improved on BDI-II, whereas respectively 6% and 10% reliably deteriorated. Conclusions These findings support the assumption that CBT and STPP are equally effective treatments for patients with depressive disorders in psychiatric outpatient clinics. Additionally, they strengthen the evidence for the effectiveness of both CBT and STPP in these settings, while also highlighting that not all depressed patients respond to short-term treatment.

  Introduction: There is a lack of qualitative research that retrospectively explores how patients with major depressive disorder view their improvement in psychotherapy. Methods: Fifteen patients who received short-term cognitive behavioral therapy and psychodynamic therapy were individually interviewed approximately three years after completing therapy. Results: Some patients had altered their views on therapy, especially those who initially were uncertain of how helpful therapy had been. They said they did not realize the extent and importance of their improvement in therapy before some time had passed, which can be explained by the surprising cumulative effects of seemingly small changes. Discussion: This should make retrospective qualitative research an important part of future psychotherapy research.

  Purpose On March 12th 2020 extensive measures were implemented to prevent spread of the coronavirus disease-19 (COVID-19). These measures were commonly referred to as “lockdown”. In this study we investigate the psychological impact associated with living under these circumstances among patients with psychotic disorders receiving care from specialized mental health services in Norway. Method During early phases of lockdown, patients and clinicians receiving and providing mental health care for psychotic disorders in specialized health services at Oslo University Hospital were asked to fill out questionnaires developed for the study. 129 participants from outpatient clinics (91 patients and 38 clinicians) and 89 from inpatient wards (15 patients and 74 clinicians) were recruited. Data regarding mental health and related symptoms were analysed using Wilcoxon signed rank tests and standard multiple regression. Results Outpatients reported significantly less extensive worrying, loneliness and hallucinatory experiences during early phase lockdown compared to the two weeks prior. Reductions in loneliness were predictive of experienced improvement in subjective mental health. However, the majority of clinicians from outpatient clinics believed their patients were experiencing more worrying and loneliness. Conclusion The result of this study suggests that many patients with psychosis experienced less loneliness, excessive worrying and hallucinations during the first phase of lockdown. This contrasts the clinicians' perceptions, as the patients show signs of resilience during times of uncertainty. The limitation in the study timeframe should be noted.

  Purpose People with psychotic disorders may be particularly vulnerable to adverse effects from restrictions implemented to limit the COVID-19 pandemic. Mental health professionals may also be at risk of adverse effects. The aim of this study was to investigate the impact of potential changes in accessibility, quality of care and vocational activity on people with psychotic disorders and the impact on clinicians working in these conditions. Materials and methods Patients and clinicians in specialized mental health services for psychotic disorders answered questionnaires regarding changes in treatment, quality of treatment, vocational activity, and well-being. Data was analyzed with nonparametric tests. Results Inpatients appeared more influenced by the restrictions than outpatients, however, quality of treatment was regarded relatively unaffected. Clinicians seemed satisfied working under these conditions, though a larger portion of clinicians reported changes in treatment compared to patients. The patients who reported being affected by changes in vocational activity tended to report negative effects, but the majority reported being unaffected. Conclusion Overall, patients and clinicians appeared to cope well with the changes they experienced in accessibility, quality of care and vocational activity during the early phases of the pandemic.

  Background Research suggests that metaphors are integral to psychotherapeutic practice. We wanted to explore how 10 therapists reflect upon the use of metaphors in therapy, and how they react to some metaphors expressed by patients treated for of major depressive disorder (MDD). Methods Five therapists practicing psychodynamic therapy (PDT) and five practicing cognitive behavioral therapy (CBT) were interviewed with a semi-structured qualitative interview. Transcripts were analyzed using a thematic analysis approach. Results Our analysis resulted in two main themes: the therapeutic use of metaphors, and conflicting feelings towards metaphors used by depressed patients. Most therapists said that they do not actively listen for metaphors in therapy and many said that they seldom use metaphors deliberately. While PDT-therapists appeared more attentive to patient-generated metaphors, CBT-therapists seemed more focused on therapist-generated metaphors. Most therapists did not try to alter the patient-generated metaphors they evaluated as unhelpful or harmful. Some therapists expressed strong negative feelings towards some of the metaphors used by patients. PDT-therapists were the most critical towards the metaphor of tools and the metaphor of depression as an opponent. CBT-therapists were the most critical towards the metaphor of surface-and-depth. Conclusions These results remind us of the complexity of using metaphors in therapy, and can hopefully be an inspiration for therapists to reflect upon their own use of metaphors. Open therapeutic dialogue on the metaphor of tools, surface-depth and depression as an opponent may be necessary to avoid patient-therapist-conflicts. Trial registration Clinical Trial gov.

  Background: There is a substantial lack of qualitative research concerning individual cognitive behavioral therapy (CBT) for patients with major depressive disorder (MDD). In the present study, we wanted to explore how patients suffering from MDD experience improvement in CBT. Method: Patients with MDD (N = 10) were interviewed at therapy termination with semi-structured qualitative interviews. The transcripts were analyzed using a thematic analysis approach. Results: We identified three elements that were relevant to the process of improvement for all patients: the therapeutic relationship, the therapeutic interventions and increased insight. There is a dynamic interrelationship and synergy between these elements that may explain why patients considered the same elements as helpful, but often in different ways and at different stages of therapy. Conclusions: Highlighting the synergies and interrelationship between the elements that patients experience as helpful, may help therapists to learn from and utilize these experiences. This is a reminder of the importance of always being attentive to the individual processes of patients.

  Background In the present study, we wanted to explore which metaphors patients suffering from major depressive disorder (MDD) use to explain their experience of being in therapy and their improvement from depression. Methods Patients with MDD (N = 22) received either psychodynamic therapy (PDT) or cognitive behavioral therapy (CBT). They were interviewed with semi-structured qualitative interviews after ending therapy. The transcripts were analyzed using a method based on metaphor-led discourse analysis. Results Metaphors were organized into three different categories concerning the process of therapy, the therapeutic relationship and of improvement from depression. Most frequent were the metaphorical concepts of surface and depth, being open and closed, chemistry, tools, improvement as a journey from darkness to light and depression as a disease or opponent. Conclusions Patient metaphors concerning the therapeutic experience may provide clinicians and researchers valuable information about the process of therapy. Metaphors offer an opportunity for patients to communicate nuances about their therapeutic experience that are difficult to express in literal language. However, if not sufficiently explored and understood, metaphors may be misinterpreted and become a barrier for therapeutic change. Trial registration Clinical Trial gov. Identifier: NCT03022071.

  Background Major depressive disorder (MDD) is a prevalent psychiatric condition associated with significant disability, mortality and economic burden. Cognitive behavioral therapy (CBT) and psychodynamic psychotherapy (PDT) are found to be equally effective for patients with depression. However, many patients do not respond sufficiently to either treatment. To offer individualized treatment, we need to know if some patients benefit more from one of the two therapies. At present little is known about what patient characteristics (moderators) may be associated with differential outcomes of CBT and PDT, and through what therapeutic processes and mechanisms (mediators) improvements occur in each therapy mode. Presently only theoretical assumptions, sparsely supported by research findings, describe what potentially moderates and mediates the treatment effects of CBT and PDT. The overall aim of this study is to examine theoretically derived putative moderators and mediators in CBT and PDT and strengthen the evidence base about for whom and how these treatments works in a representative sample of patients with MDD. Methods One hundred patients with a diagnosis of MDD will be randomized to either CBT or PDT. Patients will be treated over 28 weeks with either CBT (one weekly session over 16 weeks and three monthly booster sessions) or PDT (one weekly session over 28 weeks). The patients will be evaluated at baseline, during the course of therapy, at the end of therapy, and at follow-up investigations 1 and 3 years post treatment. A large range of patient and observer rated questionnaires (specific preselected putative moderators and mediators) are included. Discussion The clinical outcome of this study may better guide clinicians when deciding what kind of treatment any individual patient should be offered. Moreover, the study aims to further our knowledge of what mechanisms lead to symptom improvement and increased psychosocial functioning.

  Background The Feeling Word Checklist (FWC) is a self-report questionnaire designed to assess therapists’ countertransference (CT) feelings. The primary aim of the study was to evaluate the psychometric properties of a brief, 12-item version of the Feeling Word Checklist (FWC-BV). The second aim was to validate the factor structure by examining the associations between the FWC-BV factors, patients’ personality pathology and therapeutic alliance (TA). Methods Therapists at 13 different outpatient units within the Norwegian Network of Personality Disorders participated, and the study includes therapies for a large sample of patients (N = 2425) with personality pathology. Over a period of 2.5 years, therapists completed the FWC-BV for each patient in therapy every 6 months. Statistical methods included exploratory (EFA) and confirmatory (CFA) factor analysis. Internal consistency was estimated using Mc Donald’s coefficient Omega (ωt). The Structured Clinical Interview for DSM-IV – Axis II (SCID II) and Mini International Neuropsychiatric Interview (MINI) were used as diagnostic instruments, and patient-rated TA was assessed using the Working Alliance Inventory (WAI-SR). Results Factor analyses revealed three clinically meaningful factors: Inadequate, Idealised and Confident. These factors had acceptable psychometric properties. Most notably, a number of borderline PD criteria correlated positively with the factors Inadequate and Idealised, and negatively with the factor Confident. All the factors correlated significantly with at least one of the WAI-SR subscales. Conclusions The FWC-BV measures three clinically meaningful aspects of therapists’ CT feelings. This brief version of the FWC seems satisfactory for use in further research and in clinical contexts.

  Violent victimization in persons with severe mental illness has long-term adverse consequences. Little is known about the long-term prevalence of victimization in first episode psychosis, or about factors affecting victimization throughout the course of illness. To assess the prevalence of violent victimization during a 10-year follow-up period in a group of first episode psychosis (FEP) patients, and to identify early predictors and risk factors for victimization. A prospective design was used with comprehensive assessments of violent victimization, treatment variables and functioning at baseline and during 10-year follow-up. A clinical epidemiological sample of FEP patients (n= 298) was studied. FEP patients in our study were at a 3.5 times greater risk of victimization as compared to the normal population. During the 10-year follow-up period, 23% of subjects fell victim to one or more violent assaults. Victimized patients were younger and reported less occupational activity. At 10-year follow-up, victimization was associated with more concomitant drug use, alcohol misuse and violent behavior, but not with a worse clinical or functional outcome. Treatment programs should focus on risk factors for victimization and develop behavioral alternatives to mitigate risk in FEP patients.

  Background: First episode psychosis (FEP) patients have an increased risk for violence and criminal activity prior to initial treatment. However, little is known about the prevalence of criminality and acts of violence many years after implementation of treatment for a first episode psychosis. Aim: To assess the prevalence of criminal and violent behaviors during a 10-year follow-up period after the debut of a first psychosis episode, and to identify early predictors and concomitant risk factors of violent behavior. Method: A prospective design was used with comprehensive assessments of criminal behavior, drug abuse, clinical, social and treatment variables at baseline, five, and 10-year follow-up. Additionally, threatening and violent behavior was assessed at 10-year follow-up. A clinical epidemiological sample of first-episode psychosis patients (n= 178) was studied. Results: During the 10-year follow-up period, 20% of subjects had been apprehended or incarcerated. At 10-year follow-up, 15% of subjects had exposed others to threats or violence during the year before assessment. Illegal drug use at baseline and five-year follow-up, and a longer duration of psychotic symptoms were found to be predictive of violent behavior during the year preceding the 10-year follow-up. Conclusion: After treatment initiation, the overall prevalence of violence in psychotic patients drops gradually to rates close to those of the general population. However, persistent illicit drug abuse is a serious risk factor for violent behavior, even long after the start of treatment. Achieving remission early and reducing substance abuse may contribute to a lower long-term risk for violent behavior in FEP patients.

  Cognitive deficits are documented in first-episode psychosis (FEP), but the continuing course is not fully understood. The present study examines the longitudinal development of neurocognitive function in a five year follow-up of FEP-patients, focusing on the relation to illness severity, as measured by relapses and diagnostic subgroups. The study is an extension of previous findings from the TIPS-project, reporting stability over the first two years. Sixty-two FEP patients (53% male, age 28 ± 9 years) were neuropsychologically examined at baseline and at 1, 2, and 5 year follow-ups. The test battery was divided into five indices; Verbal Learning, Executive Function, Impulsivity, Motor Speed, and Working Memory. To investigate the effect of illness severity, the sample was divided in groups based on number of relapses, and diagnostic subgroups, respectively. Impulsivity and Working Memory improved significantly in the first two years, followed by no change over the next three years. Motor Speed decreased significantly from 2 to 5 years. Number of relapses was significantly related to Verbal Learning and Working Memory, showing a small decrease and less improvement, respectively, in patients with two or more episodes. No significant association was found with diagnostic group. Neurocognitive stability as well as change was found in a sample of FEP-patients examined repeatedly over 5 years. Of potential greater importance for understanding how psychotic illnesses progress, is the finding of significant associations between neurocognition and number of relapses but not diagnostic group, indicating that neurocognition is more related to recurring psychotic episodes than to the descriptive diagnosis per se.

  Objective: Neurocognitive impairment is commonly reported at onset of psychotic disorders. However, the long-term neurocognitive course remains largely uninvestigated in first episode psychosis (FEP) and the relationship to clinically significant subgroups even more so. We report 10 year longitudinal neurocognitive development in a sample of FEP patients, and explore whether the trajectories of cognitive course are related to presence of relapse to psychosis, especially within the first year, with a focus on the course of verbal memory. Method: Forty-three FEP subjects (51% male, 28 ± 9 years) were followed-up neurocognitively over five assessments spanning 10 years. The test battery was divided into four neurocognitive indices; Executive Function, Verbal Learning, Motor Speed, and Verbal Fluency. The sample was grouped into those relapsing or not within the first, second and fifth year. Results: The four neurocognitive indices showed overall stability over the 10 year period. Significant relapse by index interactions were found for all indices except Executive Function. Follow-up analyses identified a larger significant decrease over time for the encoding measure within Verbal Memory for patients with psychotic relapse in the first year [F(4, 38) = 5.8, p = 0.001, η2 = 0.40]. Conclusions: Main findings are long-term stability in neurocognitive functioning in FEP patients, with the exception of verbal memory in patients with psychotic relapse or non-remission early in the course of illness. We conclude that worsening of specific parts of cognitive function may be expected for patients with on-going psychosis, but that the majority of patients do not show significant change in cognitive performance during the first 10 years after being diagnosed.

  For at pasientene skal få persontilpasset behandling, er det viktig at psykiatere er oppdaterte innen nevrobiologi og medisinering, men også har psykoterapeutisk kompetanse. Derfor må spesialisthelsetjenesten ha organisatoriske rammer for å legge til rette for videreutdannelse, i de evidensbaserte og velutviklede psykoterapeutiske metodene som inngår i spesialistutdanningene i BUP og VOP.
