  Background: Symptoms of depression are frequent in youth and may develop into more severe mood disorders, suggesting interventions should take place during adolescence. However, young people tend not to share mental problems with friends, family, caregivers, or professionals. Many receive misleading information when searching the internet. Among several attempts to create mental health services for adolescents, technological information platforms based on psychoeducation show promising results. Such development rests on established theories and therapeutic models. To fulfill the therapeutic potential of psychoeducation in health technologies, we lack data-driven research on young peoples’ demand for information about depression. Objective: Our objective is to gain knowledge about what information is relevant to adolescents with symptoms of depression. From this knowledge, we can develop a population-specific psychoeducation for use in different technology platforms. Methods: We conducted a qualitative, constructivist-oriented content analysis of questions submitted by adolescents aged 16-20 years to an online public information service. A sample of 100 posts containing questions on depression were randomly selected from a total of 870. For analysis, we developed an a priori codebook from the main information topics of existing psychoeducational programs on youth depression. The distribution of topic prevalence in the total volume of posts containing questions on depression was calculated. Results: With a 95% confidence level and a ±9.2% margin of error, the distribution analysis revealed the following categories to be the most prevalent among adolescents seeking advice about depression: self-management (33%, 61/180), etiology (20%, 36/180), and therapy (20%, 36/180). Self-management concerned subcategories on coping in general and how to open to friends, family, and caregivers. The therapy topic concerned therapy options, prognosis, where to seek help, and how to open up to a professional. We also found young people dichotomizing therapy and self-management as opposite entities. The etiology topic concerned stressors and risk factors. The diagnosis category was less frequently referred to (9%, 17/180). Conclusions: Self-management, etiology, and therapy are the most prevalent categories among adolescents seeking advice about depression. Young people also dichotomize therapy and self-management as opposite entities. Future research should focus on measures to promote self-management, measures to stimulate expectations of self-efficacy, information about etiology, and information about diagnosis to improve self-monitoring skills, enhancing relapse prevention.

  Background: Cognitive impairment may be a risk factor for, as well as a consequence of, psychosis. Non-remitting symptoms, premorbid functioning, level of education, and socioeconomic background are known correlates. A possible confounder of these associations is substance use, which is common among patients with psychosis and linked to worse clinical outcomes. Studies however show mixed results for the effect of substance use on cognitive outcomes. In this study, the long-term associations of substance use with cognition in a representative sample of first-episode psychosis patients were examined. Methods: The sample consisted of 195 patients. They were assessed for symptom levels, function, and neurocognition at 1, 2, 5, and 10 years after first treatment. Test scores were grouped into factor analysis-based indices: motor speed, verbal learning, visuomotor processing, verbal fluency, and executive functioning. A standardized composite score of all tests was also used. Patients were divided into four groups based on substance-use patterns during the first 2 years of treatment: persistent users, episodic users, stop-users, and nonusers. Data were analyzed using linear mixed effects modeling. Results: Gender, premorbid academic functioning, and previous education were the strongest predictors of cognitive trajectories. However, on motor speed and verbal learning indices, patients who stopped using substances within the first 2 years of follow-up improved over time, whereas the other groups did not. For verbal fluency, the longitudinal course was parallel for all four groups, while patients who stopped using substances demonstrated superior performances compared with nonusers. Persistent users demonstrated impaired visuomotor processing speed compared with nonusers. Within the stop- and episodic use groups, patients with narrow schizophrenia diagnoses performed worse compared with patients with other diagnoses on verbal learning and on the overall composite neurocognitive index. Discussion: This study is one of very few long-term studies on cognitive impairments in first-episode psychosis focusing explicitly on substance use. Early cessation of substance use was associated with less cognitive impairment and some improvement over time on some cognitive measures, indicating a milder illness course and superior cognitive reserves to draw from in recovering from psychosis.

  Background There is emerging evidence for the effectiveness of psychodynamic psychotherapy for depressive disorders. However, we know less of how this relation-focused therapy mode is experienced and what the patients themselves identify as helpful. Hence, the purpose of this study is to explore adolescents’ experiences of factors promoting improvement in psychodynamic therapy. Methods Eight female patients participating in a Norwegian study on psychodynamic therapy, the First Experimental Study of Transference Work – In Teenagers (FEST-IT), were included. The participants were offered a total number of 28 sessions. Semi-structured qualitative interviews about experiences with therapy were then conducted and analysed with systematic text condensation and hermeneutic interpretation. Results The analysis revealed four main themes. ‘Exploring oneself’ comprises autonomy and acknowledgment, openness, insight and acceptance of oneself. ‘Therapist relation and characteristics’ includes confidence and trust in and support from the therapist as well as having a trustworthy and experienced therapist. ‘Focusing on everyday life’ includes learning and practical orientation. ‘Time factors’ refers to duration and frequency. Conclusions Together with a supportive and listening therapist, the adolescents improve by exploring themselves within the frames of a time-limited treatment period. Improvement seems to be experienced through better relations to oneself and to others and by finding one’s place in the family, or at school. Adolescents value problem solving and help with concrete challenges. Hence, therapy should be tailored to the needs of adolescents with depression and incorporate the challenges they face in their everyday life.

  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: Previous studies have shown that individuals with schizophrenia exhibit higher levels of unhelpful metacognitive beliefs than healthy controls, but no studies have explored metacognitive beliefs in early psychosis. Aims: We examined i) differences in levels of unhelpful metacognitive beliefs between psychosis spectrum disorders, and healthy controls, and ii) to what extent demographic and clinical characteristics predicted levels of metacognitive beliefs in the early treated phases of psychotic disorders. Method: Patients were included within two years of first treatment for a psychotic disorder (N=92). They were assessed on premorbid adjustment, psychotic symptoms, anxiety/depression, and self-reported metacognitive beliefs (MCQ-30). Ninety-seven controls also completed MCQ-30. Predictors of metacognitive beliefs were explored with multiple linear regression analyses. Results: Patients scored significantly higher than controls on all metacognitive subscales except positive beliefs about worry. The regression model explained 14—38% of the variance on each metacognitive subscale. Current affective symptoms explained a significant amount of variance on all subscales, except positive beliefs about worry. Childhood (premorbid) social adjustment predicted a significant amount of the variance on all subscales, except cognitive confidence. Duration of untreated psychosis contributed significantly to more unhelpful beliefs about cognitive confidence. Negative symptoms predicted lower scores on cognitive self-consciousness. Conclusion: Affective symptoms and childhood social adjustment could be important predictors of unhelpful metacognitive beliefs in the early treated phases of psychosis, indicating potential psychopathological relationships that warrant further investigation for clinical relevance.

  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.

  Although several reviews show that cognitive behavioral therapy (CBT) is an effective treatment for patients with chronic psychosis, the effects of CBT on patients with a first-episode psychosis are less clear. Patients undergoing a first-episode psychosis are unique in that not only are they struggling with the symptoms of the disease, but also the realization of the diagnosis. Understanding how the disease will impact their lives with respect to changes in social goals, roles, and status can also lead to depression, anxiety and low self-esteem. The main aim of the present study is to describe two clinical cases in order to demonstrate the application of CBT in first-episode psychosis patients in an early stage of their psychosis. The two cases are individuals who were in an ongoing CBT trial for first-episode psychosis patients with symptoms of social anxiety, depression, and low self-esteem. Individual case formulations based on these symptoms were developed. Psychoeducation, normalizing, evaluation of negative automatic thoughts and dysfunctional schematic beliefs, and focusing on the negative consequences of safety behavior were the main treatment targets in attempting to improve the patients' symptoms and functioning. Both patients showed improvement in depressive symptoms, self-esteem, and general functioning. The cases described suggest that treatment designed to target depression, anxiety, and self-esteem in patients with first-episode psychosis could have potential beneficial effects; specific studies of this approach are recommended

  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.

Show summary

  Background: Major depressive disorder (MDD) is a world-leading cause of disability. The available treatments are not effective in all patients, and there is a significant need for more effective treatment options. Here we present the protocol for an investigator-initiated and publicly funded trial of MDMA-assisted therapy (MDMA-AT) for MDD. This single-site, open-label study investigates the proof of principle and safety of MDMA-AT in participants with MDD and provides an initial impression of treatment effectiveness. Methods: A total of 12 participants [>18 years] with DSM-5 diagnosis of MDD will receive a flexible dose of MDMA in a therapeutic setting on two dosing days over a 4 week period preceded by three preparatory sessions. Each MDMA dosing session will be followed by three integration sessions. The primary outcome is change in MDD symptom severity, as measured by the mean change in MADRS scores from Baseline to 8 weeks after the second MDMA session. The secondary outcome is change in functional impairment, as evaluated by the mean change in Sheehan Disability Scale scores from Baseline to 8 weeks after the second MDMA session. Safety measures include vital signs, the incidence of Adverse Events and suicidality as measured by the Colombia-Suicide Severity Rating Scale. Discussion: This proof of principle trial will inform the development of fully powered clinical trials, optimize the protocol for the administration of MDMA-AT in participants with MDD and explore uncertainties including barriers to recruitment, retention and acceptability of MDMA-AT as a treatment for MDD.

  Aim: There is an emerging empirical support for the effect of psychodynamic psychotherapy in adolescents. However, there is lack of knowledge in how psychodynamic therapy works for depressed adolescents, how they experience the therapy process and the factors contributing to positive change. Little is known when it comes to adolescent patients’ own experiences of what they found helpful and leading to less symptoms and better interpersonal relationships. The aim of this study was to explore what adolescents themselves recognised as helpful during therapy. Method: An interview guide was developed, focusing on the experiences of the therapy process from the adolescents’ point of view, and what they after treatment identified as helpful factors. Main topics were on how therapy was experienced, what within therapy was helpful – or not so helpful, and how therapy affected important relations and areas in the adolescents’ everyday life. Explorative, semi-structured interviews were conducted with nine, female adolescents. The interviews lasted for approximately one hour, was audio recorded and transcribed verbatim. The transcripts were analysed with thematic content analysis, looking for similarities and differences among the adolescents’ utterances. Results: During the analysis of the transcribed interviews, thematic areas emerged. They were categorised in three main groups with several sub themes. The main areas were Exploring of self, Relational work, and Time. Discussion: Categories and themes will be presented and discussed. Keywords: Psychotherapy change, adolescent depression, patients’ perspective.
