Cognitive behavioral therapy for psychosis (CBT) is an effective treatment in adult patients with schizophrenia. However, no randomized controlled and blinded trial in adolescents with early-onset psychosis (EOP) has been conducted. Therefore, the present pilot study explores the acceptance, tolerability, feasibility, and safety of a modified CBT in adolescents with EOP. Twenty-five adolescents with EOP were randomized to either 9 months (20 sessions) of CBT + treatment as usual (TAU) or TAU alone. The primary endpoint was the PANSS-positive subscale (P1-7). Secondary endpoints included psychopathology, global functioning, and quality of life (QoL). Acceptance, tolerability, feasibility, and safety were assessed. Blinded assessments took place by the end of the treatment (9 months) and at 24-month follow-up. Despite improvements in both groups and lack of statistical significance between CBT + TAU and TAU regarding the primary endpoint, we observed between-group effect sizes of at leastd = 0.39 in favor of CBT + TAU at post-treatment for delusions, negative symptoms, functioning and QoL after the intervention and effect sizes of at leastd = 0.35 after 24 months. CBT in EOP was highly acceptable (73.5% agreed to randomization), well-tolerated (83.1% attendance rate, no drop-outs), and safe (one serious adverse event (SAE) in CBT + TAU in comparison with six SAEs in TAU). These findings suggest that CBT adapted to the needs of adolescents with EOP is a promising approach regarding negative symptoms, functioning, and QoL. CBT is a safe and tolerable treatment. However, due to the small sample size and the pilot character of the study, these conclusions are limited, and should be tested in a larger, adequately powered randomized controlled trial.

Patients with schizophrenia suffer from stigma and discrimination due to their illness. Yet it is not well examined how experiences of stigma and discrimination express at the early illness stage and how they develop subsequently. Therefore, clinical and psycho-social correlates of stigma experiences and perceived stigma are analyzed in patients with first-episode schizophrenia over the course of 1year after their first in-patient treatment. Questionnaire data assessed within the multi-centre-RCT First-Episode Study of the German Research Network on Schizophrenia were analyzed. Patients with first-episode schizophrenia were assessed 8weeks after their first in-patient treatment (post-acute assessment) and 1year later. N=48 (post-acute) and N=24 (1-year follow-up) patients provided questionnaire data appropriate for analyses, with N=12dyads. These data included burden due to stigma experiences (B-STE), perceived stigma (PDDQ), clinical (PANSS, CDSS, CGI, GAF, SAS) and psycho-social factors (LQLP, FSNK-self-esteem, KK-Scale). Cross-lag-correlation models showed a causal relation between stigma experiences (post-acute) and reduced self-esteem after 1year. Multiple regression models revealed different models for experienced and perceived stigma. Factors associated with higher stigma experiences were older age, worse clinical global impression, better social adjustment, lower self-esteem, and the belief that illness is not driven by chance or fate. The different associations between psycho-social factors and stigma experiences and perceived stigma demonstrate the complexity of this inter-relationship. The results have practical implications for psycho-educational and other therapeutic interventions addressing stigma coping. Since the sample was small and selective, replication studies are needed.

Background: The objective of this study is to test the conflicting theories concerning the association of negative self and other schemata and paranoid ideation. Methods: A risk-based approach, including risk stratification, is used to gain insight into the association of the negative self and other schemata that may be shared by individuals or differentiate between individuals at clinical high risk (CHR) for a first-episode psychosis and those with full-blown psychosis. The dataset includes a sample of individuals at CHR (n = 137) and a sample of individuals with persisting positive symptoms (PPS, n = 211). The CHR sample was subdivided according to a prognostic index yielding 4 CHR sub-classes with increasing risk for transition to psychosis. Results: Negative beliefs about the self were associated with paranoid ideation in CHR and a lower risk state. In the highest risk state and full-blown psychosis, there is an association with negative beliefs about others. Conclusion: These findings are in line with theories suggesting a switch from a predominantly activated negative self-schema to a malevolent others-schema in association with paranoid ideation along the risk-continuum. However, due to methodological limitations these results should be replicated by future studies.

Introduction The aim of this study was to evaluate antidepressant add-on treatment within the acute treatment of schizophrenia spectrum disorder patients. Methods Antidepressant add-on was evaluated in 365 patients within a naturalistic multicenter study. Patients with/without antidepressant add-on were compared regarding clinical and treatment-related variables, response and remission, and remission of depressive and negative symptoms. The efficacy of antidepressant add-on treatment was furthermore analyzed applying marginal structure models. Results Twenty-three percent of the patients received antidepressant add-on for a mean duration of 50.28 (33.42) days. Patients with the diagnosis of a schizoaffective disorder, multiple illness episodes, and a longer duration of their illness as well as those with significantly fewer baseline positive symptoms, more negative and depressive symptoms, more side effects, and less subjective well-being were augmented with antidepressants. At discharge no significant effect of antidepressant add-on treatment was observed in terms of a 25 % improvement (p = 0.2623), a 50 % improvement (p = 0.3946), remission (p = 0.0552), or remission of depressive (p = 0.6336) and negative symptoms (p = 0.8756). Also, when analyzing marginal structure models considering the diagnostic subgroups, no significant effect was found. Discussion Add-on with antidepressants is common. A final recommendation in terms of this strategy's efficacy cannot be given.

Objective: Cognitive models suggest that the self-concept of persons with psychosis can be fundamentally affected. Self-concepts were found to be related to different symptom domains when measured concurrently. Longitudinal investigations to disentangle the possible causal associations are rare. Method: We examined a sample of 160 people with a diagnosis of schizophrenia who took part in a psychotherapy study. All participants had the DSM-IV diagnosis of a schizophrenia and pronounced negative symptoms. Neurocognition, symptoms, and self-concepts were assessed at two time points 12 months apart. Structural equation modeling was used to test whether symptoms influence self-concepts (scar-model) or self-concepts affect symptoms (vulnerability model). Results: Negative symptoms correlated concurrently with self-concepts. Neurocognitive deficits are associated with more negative self-concepts 12 months later. Interpersonal self-concepts were found to be relevant for paranoia. Conclusion: The findings implicate that if deficits in neurocognition are present, fostering a positive self-concept should be an issue in therapy. Negative interpersonal self-concept indicates an increased risk for paranoid delusions in the course of 1 year. New aspects for cognitive models in schizophrenia and clinical implications are discussed.
