Treatment Goals for Patients with Schizophrenia - A Narrative Review of Physician and Patient Perspectives.

INTRODUCTION: There are many possible treatment goals for patients with schizophrenia. Two major perspectives on treatment goals are the patient's and the physician's perspective. Patient-centered treatment mandates that an individual patient's treatment goals are taken into account when treatment is planned. In this narrative review, we address the commonalities and differences of the patient's and physician's perspectives. METHODS: We searched for literature on treatment goals for patients with schizophrenia from the last 10 years. RESULTS: Fifty-two relevant records were identified, 4 of which directly compare patient's and physician's perspectives. Two further articles used the same set of goals to ask patients or physicians for their assessment. DISCUSSION: Agreement between patients and physicians regarding valuation of treatment goals was high. However, physicians tended to put more emphasis on the classical "textbook" goals of symptom resolution and functioning, while patients stressed well-being and quality of life more. Results on treatment goals from patients are difficult to generalize, since recruiting representative patient samples is challenging and patient subgroups may have differing priorities.

What happens with schizophrenia patients after their discharge from hospital? Results on outcome and treatment from a "real-world" 2-year follow-up trial.

Aim of the study was to examine the course of schizophrenia patients within 2 years after discharge. Within a multicenter study of the German Competence Network on Schizophrenia, patients suffering from a schizophrenia spectrum disorder were examined regarding their psychopathological improvement, tolerability, and the treatment regime applied during hospitalization and a 2-year follow-up period. Response, remission, the level of everyday functioning, and relapse were furthermore evaluated during the follow-up period using established definitions for these outcome domains. The psychopharmacological treatment was specifically evaluated in terms of a potential association with relapse. 149 patients were available for analysis, with 65% of the patients being in response, 52% in symptomatic remission, and 64% having a satisfiable everyday functioning 2 years after their discharge from hospital. Despite these favorable outcome rates, 63% of the patients suffered from a relapse within the 2-year follow-up period with 86% of these patients being rehospitalized. Discharge non-responder and non-remitter were twice as likely to relapse during follow-up. A significant decrease of side-effects was observed with negligible rates of extrapyramidal side-effects, sedation, and weight gain during follow-up. Patients receiving treatment with atypical antipsychotics were found to have the lowest risk to relapse (p < 0.0001). The results highlight the natural and unsteady course of schizophrenia in most patients underlining the need to develop more specific treatment strategies ensuring ongoing stability and preventing relapse.

Promoting stigma coping and empowerment in patients with schizophrenia and depression: results of a cluster-RCT.

There is a need for interventions supporting patients with mental health conditions in coping with stigma and discrimination. A psycho-educational group therapy module to promote stigma coping and empowerment (STEM) was developed and tested for efficacy in patients with schizophrenia or depression. 30 clinical centers participated in a cluster-randomized clinical trial, representing a broad spectrum of mental health care settings: in-patient (acute treatment, rehabilitation), out-patient, and day-hospitals. As randomized, patients in the intervention group clusters/centers received an illness-specific eight sessions standard psychoeducational group therapy plus three specific sessions on stigma coping and empowerment ('STEM'). In the control group clusters the same standard psychoeducational group therapy was extended to 11 sessions followed by one booster session in both conditions. In total, N = 462 patients were included in the analysis (N = 117 with schizophrenia spectrum disorders, ICD-10 F2x; N = 345 with depression, ICD-10 F31.3-F31.5, F32-F34, and F43.2). Clinical and stigma-related measures were assessed before and directly after treatment, as well as after 6 weeks, 6 months, and 12 months (M12). Primary outcome was improvement in quality of life (QoL) assessed with the WHO-QOL-BREF between pre-assessment and M12 analyzed by mixed models and adjusted for pre-treatment differences. Overall, QoL and secondary outcome measures (symptoms, functioning, compliance, internalized stigma, self-esteem, empowerment) improved significantly, but there was no significant difference between intervention and control group. The short STEM module has proven its practicability as an add-on in different settings in routine mental health care. The overall increase in empowerment in both, schizophrenia and depression, indicates patients' treatment benefit. However, factors contributing to improvement need to be explored.The study has been registered in the following trial registers.

Theory of mind, emotion recognition, delusions and the quality of the therapeutic relationship in patients with psychosis - a secondary analysis of a randomized-controlled therapy trial.

BACKGROUND: Cognitive models of psychosis postulate an important role of Theory of mind (ToM) in the formation and maintenance of delusions, but research on this plausible conjecture has gathered conflicting findings. In addition, it is still an open question whether problems in emotion recognition (ER) are associated with delusions. We examined the association of problems in ToM and ER with different aspects of delusions in a large sample of patients with psychosis enrolled in a therapy trial. This also enabled us to explore the possible impact of ToM and ER on one part of patients' social life: the quality of their therapeutic relationship. METHODS: Patients with psychotic disorders and delusions and/or hallucinations (n = 185) and healthy controls (n = 48) completed a ToM picture sequencing task and an ER task. Subsequently, patients were enrolled in a randomized-controlled Cognitive Behavior Therapy (CBT) trial (ISRCTN29242879). Patients and therapists rated the quality of the therapeutic relationship during the first five sessions of therapy. RESULTS: In comparison to controls, patients were impaired in both ToM and ER. Patients with deficits in ER experienced more severe delusional distress, whereas ToM problems were not related to delusions. In addition, deficits in ER predicted a less favorable therapeutic relationship and interactional problems viewed by the therapist. Impaired ER also moderated (increased) the negative influence of delusions on the therapeutic relationship and interactional difficulties viewed by the therapist. CONCLUSIONS: Cognitive models on the formation and maintenance of delusions should consider ER as a potential candidate that might be related to the formation and maintenance of delusional distress, whereas problems in ToM might not be directly related to delusions and secondary dimensions of delusions. In addition, problems in ER in patients with psychosis might have an impact on the quality of the therapeutic relationship and patients with problems in ER are more likely to be viewed as problematic by their therapists. Nevertheless, training ER might be a way to improve the quality of the therapeutic relationship and potentially the effectiveness of CBT or other interventions for patients with psychosis.

Problems in measuring the JTC-bias in patients with psychotic disorders with the fish task: a secondary analysis of a baseline assessment of a randomized controlled trial.

BACKGROUND: The jumping to conclusions bias (JTC) is considered to be an important causal factor in theoretical models for the formation and maintenance of delusions. However, recent meta-analytic findings show a rather equivocal pattern of results regarding associations between JTC and delusions. Thus, the present study aims to investigate in a large sample whether the JTC-bias is more pronounced in patients with psychotic disorders in comparison to controls and whether the JTC bias is associated with a more severe delusional conviction, persecutory delusions, and positive symptoms in general. METHODS: Patients with psychotic disorders (n = 300) enrolled in a therapy trial and healthy controls (n = 51) conducted a variant of the beads task (fish task) as a measure for the JTC-bias at the start of the trial. Further, clinical interviews were used to assess patients' delusional severity and delusional conviction. RESULTS: There were no statistically significant differences between patients with psychotic disorders (with 53% displaying the JTC-bias) and controls (41%). Furthermore, there were no statistically significant correlations between JTC measures and persecutory delusions, delusional conviction, and positive symptoms. CONCLUSIONS: We found no differences in JTC between patients with psychotic disorders and healthy controls, which is in part in line with meta-analytic findings using a wide range of JTC task variants. Interestingly, patients with psychotic disorders displayed JTC rates commonly found in the literature, while healthy control subjects showed an unexpectedly high level of JTC. The task variant we used in the present study (fish task) is discussed as a potential reason for our results, as it may induce a more deliberative reasoning style in controls as compared to the traditional beads task. Furthermore, possible implications for the measurement of the JTC-bias, in general, are discussed.

Cognitive behavioral therapy in adolescents with early-onset psychosis: a randomized controlled pilot study.

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 least d = 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 least d = 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.

Stigma experiences and perceived stigma in patients with first-episode schizophrenia in the course of 1 year after their first in-patient treatment.

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 1 year 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 8 weeks after their first in-patient treatment (post-acute assessment) and 1 year later. N = 48 (post-acute) and N = 24 (1-year follow-up) patients provided questionnaire data appropriate for analyses, with N = 12 dyads. 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 1 year. 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.

Self-assessment of negative symptoms - Critical appraisal of the motivation and pleasure - Self-report's (MAP-SR) validity and reliability.

OBJECTIVE: The negative symptom domain remains a major challenge concerning treatment. A valid self-report measure could assist clinicians and researchers in identifying patients with a relevant subjective burden. The Motivation and Pleasure - Self Report (MAP-SR) derives from the CAINS and is supposed to reflect the "amotivation" factor of negative symptoms. We evaluated different aspects of the scale's reliability and validity. This is the first factorial analysis as well as the first analysis of test-retest reliability. METHODS: We assessed three samples of subjects with schizophrenia or schizoaffective disorder (n = 93) and a broad spectrum of related domains. RESULTS: We explored a 3-, 2- and 1-factor solution (explaining 50.93, 44.85 and 36.18% of variance, respectively). The factor "pleasure and hedonic activity" consists of eight items and was most robust; the factors "social motivation" and "motivation for work" were problematic. Test-retest reliability of the scale was adequate (rS = 0.63, p = .005). Neither the MAP-SR nor the "pleasure and hedonic activities" factor are associated with the PANSS negative symptom scale. There are significant associations with the observer-rated CAINS-MAP scale, experiences of pleasure, and social cognition but none with functional outcome. Discriminant validity could not be established with regards to depression and extrapyramidal symptoms. CONCLUSIONS: We found that the MAP-SR is adequate to assess anhedonia but is less suitable when assessing motivation. Therefore, we propose using the "pleasure and hedonic activity scale" to cover the "anhedonia" subdomain. We think the "motivation" part of the instrument requires reconstruction.

[Psychosis: Cognitive Behavioral Treatment Strategies]. / Psychotische Störungen: Kognitiv-verhaltens-therapeutische Behandlungsstrategien.

Cognitive behavioral therapy (CBT) is an established treatment for the patients with psychosis including schizophrenia. The evidence for the efficacy of CBT is proved by randomized clinical trials and meta-analyses. Evidence-based treatment guidelines recommend CBT for routine treatment. The aim of this paper is to give a short practical guideline for different cognitive behavioral treatment strategies. Cognitive Behavior Therapy for psychosis (CBTp) is an adaptation of general principles of CBT modified for patients with psychotic disorders. Basis of CBT are cognitive models of symptoms to identify treatment targets. The major goal is to foster every-day functioning by realizing a self-management approach. A caring, genuine and real-life oriented therapeutic attitude can help to establish a therapeutic alliance. An individualized functional analysis should be the core for every intervention. Basic strategies like psychoeducation and crisis plans are briefly described. Relatives and close friends of patients should be involved in order to improve crisis management and problem solving. Behavioral and cognitive treatment strategies for delusions, hallucinations and negative symptoms are outlined. Metacognitive treatment as well as social competence training is presented.

Validity of remission and recovery criteria for schizophrenia and major depression: comparison of the results of two one-year follow-up naturalistic studies.

The objective of the present study was the application and comparison of common remission and recovery criteria between patients with the diagnosis of schizophrenia and major depressive disorder (MDD) under inclusion of other outcome parameters. Patients with schizophrenia and MDD who were treated as inpatients at the beginning of the study were examined within two naturalistic follow-up trials from admission to discharge of an inpatient treatment period and the one-year follow-up assessment. PANSS criteria of the Remission in Schizophrenia Working Group (RSWG) for schizophrenia and HAMD criteria of the ACNP Task Force in MDD for depressive patients as well as the Clinical Global Impression-Severity Scale (CGI-S) were applied as symptomatic outcome measures additionally to functional outcome parameters. Data of 153 schizophrenia patients and 231 patients with a MDD episode have been included in the analysis. More depressive than schizophrenia patients reached a threshold score of ≤3 on the CGI-S, indicating symptomatic remission at discharge and at the one-year follow-up. In contrast similar proportions of patients reaching symptomatic remission at discharge from inpatient treatment and at the one-year follow-up in the schizophrenia and in the MDD group were found when disease-related consensus criteria (RSWG vs. ACNP Task Force) were used. Functional remission and recovery rates were significantly lower in schizophrenia than in depressive patients at the one-year follow-up visit. Common outcome criteria for remission and recovery in schizophrenia and major depression were not directly comparable. However, our results indicated a significantly poorer outcome in schizophrenia than in depressive patients according to terms of remission and recovery.

Add-on Antidepressants in the Naturalistic Treatment of Schizophrenia Spectrum Disorder - When, Who, and How?

The aim of this study was to evaluate antidepressant add-on treatment within the acute treatment of schizophrenia spectrum disorder patients. 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. 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. Add-on with antidepressants is common. A final recommendation in terms of this strategy's efficacy cannot be given.

What are residual symptoms in schizophrenia spectrum disorder? Clinical description and 1-year persistence within a naturalistic trial.

The aim of this study was to evaluate residual symptoms in patients achieving remission according to the consensus criteria and to analyze their potential influence on the patient's outcome one year after discharge. In total, 399 patients suffering from a schizophrenia spectrum disorder were evaluated within a naturalistic study. Remission status was examined using the consensus criteria. Residual symptoms were defined as any symptom present at the time-point of remission following analogous analyses performed in depressed patients. Therefore, a PANSS item with a symptom severity of >1 (= at least borderline mentally ill) was defined to be a residual symptom. Remitters with and without residual symptoms were compared regarding psychopathology, functioning and side effects. In total, 236 patients (59%) were remitters at discharge with 94% of them suffering from at least one residual symptom. The most common residual symptoms were blunted affect (49%), conceptual disorganization (42%) and social withdrawal (40%). A significant association was found between the presence of residual symptoms and the severity of side effects (p < 0.0001) and functioning (p = 0.0003) at discharge as well as between residual symptoms and the risk of relapse and chance of remission one year after discharge. Residual symptoms were highly prevalent in remitted schizophrenia inpatients following the suggested definition. Most residual symptoms were persistent baseline symptoms suggesting an ongoing illness severity. Also, the necessity to re-evaluate the consensus criteria questioning the status of remission in these patients is also pointed out.

The precuneus and the insula in self-attributional processes.

Attributions are constantly assigned in everyday life. A well-known phenomenon is the self-serving bias: that is, people's tendency to attribute positive events to internal causes (themselves) and negative events to external causes (other persons/circumstances). Here, we investigated the neural correlates of the cognitive processes implicated in self-serving attributions using social situations that differed in their emotional saliences. We administered an attributional bias task during fMRI scanning in a large sample of healthy subjects (n = 71). Eighty sentences describing positive or negative social situations were presented, and subjects decided via buttonpress whether the situation had been caused by themselves or by the other person involved. Comparing positive with negative sentences revealed activations of the bilateral posterior cingulate cortex (PCC). Self-attribution correlated with activation of the posterior portion of the precuneus. However, self-attributed positive versus negative sentences showed activation of the anterior portion of the precuneus, and self-attributed negative versus positive sentences demonstrated activation of the bilateral insular cortex. All significant activations were reported with a statistical threshold of p ≤ .001, uncorrected. In addition, a comparison of our fMRI task with data from the Internal, Personal and Situational Attributions Questionnaire, Revised German Version, demonstrated convergent validity. Our findings suggest that the precuneus and the PCC are involved in the evaluation of social events with particular regional specificities: The PCC is activated during emotional evaluation, the posterior precuneus during attributional evaluation, and the anterior precuneus during self-serving processes. Furthermore, we assume that insula activation is a correlate of awareness of personal agency in negative situations.

Low performance in attention testing is associated with reduced grey matter density of the left inferior frontal gyrus in euthyroid patients with Hashimoto's thyroiditis.

Hashimoto's thyroiditis (HT) can casually co-occur with an encephalopathy associated with autoimmune thyroid disease. Recently we found an increased occurrence of weaknesses in sustained attention and response inhibition in a subgroup of euthyroid patients with HT as obtained by the d2 attention test. Previous studies in healthy subjects and patients with brain lesions demonstrated a pivotal role for the left inferior frontal gyrus (LIFG) in these skills. Therefore, we studied the association between the performance in the d2 test and grey matter (GM) density of the LIFG in 13 euthyroid patients with HT compared to a control group of 12 euthyroid patients with other thyroid diseases. A significant correlation between GM density and d2 test total score was detected for the opercular part of the LIFG in patients with HT (p<0.001), but not in the control group (p=0.94). Regression in patients with HT was significantly stronger than in the control group (p=0.02). Moreover, GM density was significantly reduced when comparing HT patients with control patients that scored in the lower third during d2 attention testing (p<0.05). It can be concluded that in HT performance in the d2 test correlated with GM density of the LIFG. Particularly low achievement was associated with reduced GM density of this brain region suggesting an influence of autoimmune processes on the frontal cortex in this disease. This could be due to not yet known antibodies affecting brain morphology or an influence of thyroid antibodies themselves.

Emotional wellbeing of blind patients in a pilot trial with subretinal implants.

BACKGROUND: Participation in first human applications of retinal neuroprosthesis may create psychological stress for blind retinitis pigmentosa patients. The aim of this study was to assess the emotional wellbeing of patients undergoing implantation of a subretinal implant. METHODS: Nine blind patients participating in a pilot trial with subretinal implants were enlisted. The Brief Symptom Inventory (BSI), a short self-report scale of nine primary symptoms, was used to assess reaction to the psychological distress related to study participation. The number and the intensity of symptoms were analysed, and global scores for overall psychological distress (tGSI), severity of reported symptoms (tPDSI), and level number of self-reported symptoms (tPST) were calculated. The questionnaire was administered before implantation, 2-3 times during the trial and before explantation. RESULTS: There were no significant alterations during the trial for the average scores of the nine primary symptoms. One patient, however, showed values higher than the norm, for six subscores before implantation and for eight subscores before explantation. A significant improvement was found in both the overall psychological distress level (tGSI) and the severity of reported symptoms (tPDSI) at the final visit, compared to those at the study start. The number of self-reported symptoms (tPST) was not significantly altered. CONCLUSION: In the first ongoing pilot trial with an active, cable-bound subretinal implant, we found that trial participation and the implant procedure and subsequent testing did not have any adverse effects on the participants' emotional wellbeing. Their distress generally improved during study participation, rather than showing signs of decreased wellbeing.

Feasibility of six-month outpatient cognitive remediation in schizophrenia: Experience from the randomized controlled integrated social cognition and social skills therapy study.

Patients with schizophrenia often have cognitive impairments that contribute to diminished psychosocial functioning. Cognitive remediation therapy (CRT) has proven efficacy and is recommended by evidence-based treatment guidelines. Important moderators of efficacy include integration of CRT into a psychiatric rehabilitation concept and patient attendance at a sufficient number of therapy sessions. These conditions can probably best be met in an outpatient setting; however, outpatient treatment is prone to higher rates of treatment discontinuation and outpatient settings are not as well protected as inpatient ones and less closely supervised.The present study investigated the feasibility of outpatient CRT in schizophrenia over a six-month period. Adherence to scheduled sessions and safety parameters were assessed in 177 patients with schizophrenia randomly assigned to one of two matched CRT programs.Results showed that 58.8 % of participants completed the CRT (>80 % of scheduled sessions) and 72.9 % completed at least half the sessions. Predictor analysis revealed a high verbal intelligence quotient as favorable for good adherence, but this factor had only low general predictive power. During the six-month treatment phase, serious adverse events occurred in 15.8 % (28/177) of the patients, which is a comparable rate to that reported in the literature.Our findings support the feasibility of six-month outpatient CRT in schizophrenia in terms of adherence to scheduled sessions and safety. Trial registration number: NCT02678858, DRKS00010033.

Thyroid peroxidase antibody positivity is associated with symptomatic distress in patients with Hashimoto's thyroiditis.

Previous studies suggest impairments of physical, mental, and psychic well-being in patients with Hashimoto's thyroiditis (HT), but these impairments have been shown to be independent of thyroid dysfunction. In 64 euthyroid patients with HT, symptomatic distress was assessed with the Symptom Checklist-90-Revised (SCL-90-R), a 90-item multidimensional self-report symptom inventory using a 5-point rating scale. In a subgroup of patients, endocrine testing 3 years prior to the current investigation was available. Anti-thyroid peroxidase antibodies (TPO-Abs) were associated with the three SCL-90-R global indices Global Severity Index (GSI), Positive Symptom Distress Index (PSDI), and Positive Symptom Total (PST) as well as with somatization and obsessive-compulsive symptoms after adjustment for age, gender, and thyroid function as assessed by TSH levels (all p<0.05). HT patients positive for TPO-Abs showed poorer results in the three SCL-90-R global indices as well as in the three domains: somatization, obsessive-compulsive symptoms, and depression (all p≤0.02), though the aforementioned associations did not withstand sequential Bonferroni correction for multiple testing. In contrast, TPO-Abs positivity, defined as TPO-Abs >100 IU/l, significantly predicted poorer psychosocial well-being in all of the three SCL-90-R global indices after three years, even after correction (all p≤0.02). In conclusion, high TPO-Abs are associated with poor physical and psychological well-being and appear to predict future health perception in HT patients.

Adverse effects of cognitive behavioral therapy and cognitive remediation in schizophrenia: results of the treatment of negative symptoms study.

This study examined the frequency and extent of detrimental effects of cognitive behavioral therapy (CBT) for psychosis. In a randomized clinical trial, we investigated the efficacy of CBT for the reduction of negative symptoms as compared with cognitive remediation (CR) in schizophrenia patients (n = 198). Safety was addressed through assessment of severe adverse events (SAEs), which were defined as suicides, suicide attempts, suicidal crises, and severe symptom exacerbations over a period of 12 months after inclusion in the study. Monthly assessments with Positive and Negative Syndrome Scale and Scale for the Assessment of Negative Symptoms allowed for the analysis of symptom increases during the treatment. There were no suicides in the trial. SAEs were observed in 10 CBT and 5 CR patients. Increases in negative symptoms occurred in 64 CBT and 58 CR patients. These differences were not significant. The maximum increase in negative symptoms under treatment, as compared with the baseline, was equal to an effect size of -0.66 in CBT patients and -0.77 in CR patients. Thus, the SAE rate was comparable between both interventions and was relatively low, given the severity of the psychotic disorder. Therapists should be aware of a subgroup of patients who show symptom increases with large effect sizes and might require more intensive care.

Specificity of jumping to conclusions and attributional biases: a comparison between patients with schizophrenia, depression, and anorexia nervosa.

INTRODUCTION: The knowledge of the specificity of cognitive biases in psychiatric disorders is important in order to develop disorder-specific cognitive models and therapies. This cross-sectional study aimed to investigate the specificity of jumping to conclusions (JTC) and attributional biases (AB) for patients with schizophrenia. METHODS: Twenty patients with paranoid schizophrenia were compared with patients with depression (n=20) and with anorexia nervosa (n=15) and nonclinical controls (n=55). All participants were administered a modified version of the beads task (JTC), a revised German version of the Internal, Personal, and Situational Attributions Questionnaire (AB), and several symptom and neurocognitive measures. RESULTS: The proportion of patients with JTC bias in the schizophrenia group was, at the descriptive level, higher than in the depression and the anorexia groups. Regarding AB, the schizophrenia group showed a significantly stronger externalising but not personalising bias than the clinical control groups. Neither JTC nor attributional biases were significantly associated with delusions in general or persecutory delusion. CONCLUSIONS: We found evidence for the specificity of an externalising bias for paranoid schizophrenia. Concerning JTC bias the evidence was less clear. Whether the modification of those biases through psychological interventions would have an effect on psychopathology should be investigated in the context of clinical trials.

Evaluating depressive symptoms in schizophrenia: a psychometric comparison of the Calgary Depression Scale for Schizophrenia and the Hamilton Depression Rating Scale.

BACKGROUND: The aim of this study was to compare two measures of depression in patients with schizophrenia and schizophrenia spectrum disorder, including patients with delusional and schizoaffective disorder, to conclude implications for their application. SAMPLING AND METHODS: A total of 278 patients were assessed using the Calgary Depression Scale for Schizophrenia (CDSS) and the Hamilton Depression Rating Scale (HAMD-17). The Positive and Negative Syndrome Scale (PANSS) was also applied. At admission and discharge, a principal component analysis was performed with each depression scale. The two depression rating scales were furthermore compared using correlation and regression analyses. RESULTS: Three factors were revealed for the CDSS and HAMD-17 factor component analysis. A very similar item loading was found for the CDSS at admission and discharge, whereas results of the loadings of the HAMD-17 items were less stable. The first two factors of the CDSS revealed correlations with positive, negative and general psychopathology. In contrast, multiple significant correlations were found for the HAMD-17 factors and the PANSS subscores. Multiple regression analyses demonstrated that the HAMD-17 accounted more for the positive and negative symptom domains than the CDSS. CONCLUSIONS: The present results suggest that compared to the HAMD-17, the CDSS is a more specific instrument to measure depressive symptoms in schizophrenia and schizophrenia spectrum disorder, especially in acutely ill patients.
