Pillny M, Hallford DJ, Böge K. The Nature of Mental Imagery and Its Relationship With Amotivational Psychopathology in People With Schizophrenia Spectrum Disorders. Behav Ther 2024; 55:885-897. [PMID: 38937057 DOI: 10.1016/j.beth.2024.01.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 12/14/2023] [Accepted: 01/09/2024] [Indexed: 06/29/2024]
Abstract
Many people with schizophrenia spectrum disorders (SSDs) experience profound amotivation, which is strongly related to anticipatory anhedonia. Yet, the neuropsychological fundamentals of anticipatory anhedonia and amotivation are barely understood, resulting in a lack of effective treatments for these patients. Aberrancies in positive mental imagery may interfere with the anticipation of pleasure and could thus explain anticipatory anhedonia and amotivation. However, the nature of mental imagery and its relationship with amotivational psychopathology in SSD is largely unknown. In this preregistered study, we therefore examined mental imagery characteristics and their relation to anticipatory anhedonia, amotivation, and daily life activity in SSD. TheN = 86 participants included individuals with SSD (n = 43) and demographically matched healthy controls (n = 43). Mental imagery, anticipatory pleasure, amotivation, and activity engagement were assessed with structured interviews and self-report questionnaires. Ecological momentary assessment was used to measure state anticipatory pleasure and activity engagement in daily life (n = 81). Compared to the control group, the SSD group showed comparable quantity, but less vividness of mental imagery. Reduced vividness of mental imagery in SSD was significantly associated with higher anticipatory anhedonia, amotivation, and low activity engagement in cross-sectional and prospective analyses. Reduced mental imagery vividness may cause a lack of internal incentive to seek pleasurable experiences and could explain amotivation. Interventions aiming to improve mental imagery vividness and related anticipatory pleasure responses in SSD may be effective in targeting amotivation.

Level of structural integration in people with schizophrenia and schizoaffective disorders - applicability and associations with clinical parameters. Front Psychiatry 2024; 15:1388478. [PMID: 38911709 PMCID: PMC11192590 DOI: 10.3389/fpsyt.2024.1388478] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Accepted: 05/13/2024] [Indexed: 06/25/2024] Open
Abstract
Introduction The psychic structure of people with psychosis has been the subject of theoretical and qualitative considerations. However, it has not been sufficiently studied quantitatively. Therefore, the aim of this study was to explore the structural abilities of people diagnosed with schizophrenia and schizoaffective psychosis using the Levels of Structural Integration Axis of the Operationalized Psychodynamic Diagnosis System (OPD-2-LSIA). The study aimed to determine possible associations between the OPD-2-LSIA and central parameters of illness. Additionally, possible structural differences between people diagnosed with schizophrenia and schizoaffective psychosis were tested. Methods This cross-sectional study included 129 outpatients with schizophrenia or schizoaffective disorders. Measures of structural integration, symptom load, severity of illness, cognition, and social functioning were obtained. Descriptive statistics were used to analyze the overall structural level and the structural dimensions. Correlation coefficients were computed to measure the associations between OPD-2-LSIA and variables regarding the severity of illness and psychosocial functioning. Regression models were used to measure the influence of illness-related variables on OPD-2-LSIA, and the influence of OPD-2-LSIA on psychosocial functioning. Participants diagnosed with schizophrenia and schizoaffective disorders were examined with regard to possible group differences. Results The results of the OPD-2-LSIA showed that the overall structural level was between 'moderate to low' and 'low level of structural integration'. Significant correlations were found between OPD-2-LSIA and psychotic symptoms (but not depressive symptoms), as well as between OPD-2-LSIA and psychosocial functioning. It was found that variables related to severity of illness had a significant impact on OPD-2-LSIA, with psychotic, but not depressive symptoms being significant predictors. OPD-2-LSIA was found to predict psychosocial functioning beyond symptoms and cognition. No significant differences were found between participants with schizophrenia and schizoaffective psychosis. There was also no correlation found between OPD-2-LSIA and depressive symptomatology (except for the subdimension Internal communication). Discussion Contrary to theoretical assumptions, the results of the study show a heterogenous picture of the psychic structure of people with psychosis. The associations between OPD-2-LSIA and severity of illness, particularly psychotic symptomatology, as well as the influence of OPD-2-LSIA on psychosocial functioning, are discussed.

Microstructural white matter biomarkers of symptom severity and therapy outcome in catatonia: Rationale, study design and preliminary clinical data of the whiteCAT study. Schizophr Res 2024; 263:160-168.

Abstract
The number of magnetic resonance imaging (MRI) studies on neuronal correlates of catatonia has dramatically increased in the last 10 years, but conclusive findings on white matter (WM) tracts alterations underlying catatonic symptoms are still lacking. Therefore, we conduct an interdisciplinary longitudinal MRI study (whiteCAT) with two main objectives: First, we aim to enroll 100 psychiatric patients with and 50 psychiatric patients without catatonia according to ICD-11 who will undergo a deep phenotyping approach with an extensive battery of demographic, psychopathological, psychometric, neuropsychological, instrumental and diffusion MRI assessments at baseline and 12 weeks follow-up. So far, 28 catatonia patients and 40 patients with schizophrenia or other primary psychotic disorders or mood disorders without catatonia have been studied cross-sectionally. 49 out of 68 patients have completed longitudinal assessment, so far. Second, we seek to develop and implement a new method for semi-automatic fiber tract delineation using active learning. By training supportive machine learning algorithms on the fly that are custom tailored to the respective analysis pipeline used to obtain the tractogram as well as the WM tract of interest, we plan to streamline and speed up this tedious and error-prone task while at the same time increasing reproducibility and robustness of the extraction process. The goal is to develop robust neuroimaging biomarkers of symptom severity and therapy outcome based on WM tracts underlying catatonia. If our MRI study is successful, it will be the largest longitudinal study to date that has investigated WM tracts in catatonia patients.

Abstract
The precise nature of the relationship between mindfulness, psychological flexibility (PF) and psychopathology in schizophrenia spectrum disorders (SSD) remains largely unclear and warrants further investigation. We recruited 43 persons with SSD and 43 controls. Our findings revealed that SSD showed lower mindfulness and PF than controls. Mindfulness was associated with higher PS, anticipatory pleasure, behavioral activation, and lower depressive and negative symptoms. PS was associated with lower depressive and negative symptoms and higher anticipatory pleasure and behavioral activation. The outcomes imply that targeting mindfulness and PF may prove beneficial in alleviating the amotivational psychopathology exhibited in SSD.

Abstract
BACKGROUND Psychotic disorders are a leading cause of disability in young adults. Antipsychotics have been the primary intervention for psychosis for over 60 years, and yet, we have made little progress in treating negative symptoms, neurocognition, and functional disability. There is growing evidence that cannabidiol (CBD) is effective in treating positive psychotic symptoms, possibly also negative and neurocognitive symptoms, and moreover is well tolerated compared to other psychotropic medications. Anecdotally, patients participating in the Cognitive Assessment and Risk Evaluation (CARE) Early Psychosis Treatment Program at the University of California, San Diego, are self-administering CBD and report subjective improvement in stress, anxiety, and ability to cope with symptoms. The overarching aim of the trial is to explore the effectiveness of CBD augmentation on symptoms and neurocognition in early psychosis while also exploring the mechanism of action of CBD and predictors of response to treatment. The mechanism by which cannabidiol has a therapeutic effect on psychosis is poorly understood. Recent evidence has suggested that CBD may reduce stress and pro-inflammatory biomarker levels. Endocannabinoids also have powerful roles in eating behavior, reward, and mood, indicating these neurotransmitters may play a role in reducing hyperphagia and metabolic abnormalities that are present early in the course of psychotic illness and exacerbated by antipsychotic medication. The neurophysiological effects of CBD have been studied in animal models of psychosis that show improvements in information processing in response to CBD, but there are no studies in individuals with early psychosis. METHOD A total of 120 individuals in the early stages of psychosis will be randomized to 1000 mg of CBD versus placebo as an adjunct to existing treatment in a 8-week, double-blind superiority randomized control trial. The primary outcome measures are symptoms and neurocognition. DISCUSSION We hypothesized that CBD will improve symptoms and neurocognition as well as secondary outcome measures of neurohormones, inflammation, eating behaviors, and information processing. Importantly, predictors, moderators, and mediators of the CBD effects will be examined. A better understanding of which individuals are likely to respond to CBD can inform treatment planning and personalize treatment. TRIAL REGISTRATION ClinicalTrials.gov NCT04411225.

Abstract
Introduction Treatment of severe mental illness (SMI) symptoms, especially negative symptoms and cognitive dysfunction in schizophrenia, remains a major unmet need. There is good evidence that SMIs have a strong genetic background and are characterized by multiple biological alterations, including disturbed brain circuits and connectivity, dysregulated neuronal excitation-inhibition, disturbed dopaminergic and glutamatergic pathways, and partially dysregulated inflammatory processes. The ways in which the dysregulated signaling pathways are interconnected remains largely unknown, in part because well-characterized clinical studies on comprehensive biomaterial are lacking. Furthermore, the development of drugs to treat SMIs such as schizophrenia is limited by the use of operationalized symptom-based clusters for diagnosis. Methods In line with the Research Domain Criteria initiative, the Clinical Deep Phenotyping (CDP) study is using a multimodal approach to reveal the neurobiological underpinnings of clinically relevant schizophrenia subgroups by performing broad transdiagnostic clinical characterization with standardized neurocognitive assessments, multimodal neuroimaging, electrophysiological assessments, retinal investigations, and omics-based analyzes of blood and cerebrospinal fluid. Moreover, to bridge the translational gap in biological psychiatry the study includes in vitro investigations on human-induced pluripotent stem cells, which are available from a subset of participants. Results Here, we report on the feasibility of this multimodal approach, which has been successfully initiated in the first participants in the CDP cohort; to date, the cohort comprises over 194 individuals with SMI and 187 age and gender matched healthy controls. In addition, we describe the applied research modalities and study objectives. Discussion The identification of cross-diagnostic and diagnosis-specific biotype-informed subgroups of patients and the translational dissection of those subgroups may help to pave the way toward precision medicine with artificial intelligence-supported tailored interventions and treatment. This aim is particularly important in psychiatry, a field where innovation is urgently needed because specific symptom domains, such as negative symptoms and cognitive dysfunction, and treatment-resistant symptoms in general are still difficult to treat.

Abstract
BACKGROUND The reduction of goal-directed behavior is the main characteristic in motivational negative symptoms of psychosis as it accounts for the long-term decline in psychological well-being and psychosocial functioning. However, the available treatment options are largely unspecific and show only small effects on motivational negative symptoms. Interventions that directly target the relevant psychological mechanisms are likely to be more effective. For "Goals in Focus", we translated findings from basic clinical research on mechanisms underlying motivational negative symptoms into a tailored and comprehensive novel psychological outpatient treatment program. With this study, we will test the feasibility of the therapy manual and the trial procedures. We also aim to examine first estimates of the effect size that can be expected from "Goals in Focus" to inform the sample size calculation of a subsequent fully powered trial. METHODS Thirty participants diagnosed with a schizophrenia spectrum disorder and at least moderate motivational negative symptoms will be randomly assigned to either 24 sessions of "Goals in Focus" over the course of 6 months (n = 15) or to a 6-month wait-list control group (n = 15). Single-blind assessments will be conducted at baseline (t0) and 6 months after baseline completion (t1). Feasibility outcomes include patient recruitment, retention, and attendance rates. Acceptability will be rated by trial therapists and by participants at end of treatment. Primary outcome for effect size estimation is the motivational negative symptom subscale sum score of the Brief Negative Symptom Scale at t1 corrected for baseline values. Secondary outcomes include psychosocial functioning, psychological well-being, depressive symptoms, expressive negative symptoms, negative symptom factor scores, and goal pursuit in everyday life. DISCUSSION The feasibility and acceptability data will be used to improve trial procedures and the "Goals in Focus" intervention where necessary. The treatment effect on the primary outcome will provide the basis for the sample size calculation for a fully powered RCT. TRIAL REGISTRATION 1) ClinicalTrials.gov, NCT05252039 .

Abstract
BACKGROUND This study aimed to enhance the cultural adaptation and training on administering the Arabic versions of the Calgary Depression Scale in Schizophrenia (CDSS) and The International Scale for Suicidal Thinking (ISST) to Arab schizophrenia patients in Doha, Qatar. METHODS We applied the qualitative thematic analysis of the focus group discussions with clinical research coordinators (CRCs). Five CRCs met with the principal investigator for two sessions; we transcribed the conversations and analyzed the content. RESULTS This study revealed one set of themes related to the scales themselves, like the role of the clinician-patient relationship during administration, the semantic variations in Arabic dialects, and the design of scales to assess suicide and differentiate between negative symptoms and depression. The other set of themes is relevant to the sociocultural domains of Muslim Arabs, covering religion, families' roles, and stigma. It also covered the approaches to culturally sensitive issues like suicide, taboos in Islam, and the gender roles in Arab countries and their impact on the patients' reports of their symptoms. CONCLUSIONS Our results highlight several cultural and religious aspects to tackle when approaching schizophrenia patients through in-depth discussions and training to improve the validity of the assessment tools and treatment services.

Abstract
OBJECTIVES To examine whether depressive symptoms predict receipt of cognitive-behavioural therapy for psychosis (CBTp) in individuals with psychosis. DESIGN Retrospective cross-sectional analysis of electronic health records (EHRs) of a clinical cohort. SETTING A secondary National Health Service mental healthcare service serving four boroughs of south London, UK. PARTICIPANTS 20 078 patients diagnosed with an International Classification of Diseases, version 10 (ICD-10) code between F20 and 29 extracted from an EHR database. PRIMARY AND SECONDARY OUTCOME MEASURES Primary: Whether recorded depressive symptoms predicted CBTp session receipt, defined as at least one session of CBTp identified from structured EHR fields supplemented by a natural language processing algorithm. Secondary: Whether age, gender, ethnicity, symptom profiles (positive, negative, manic and disorganisation symptoms), a comorbid diagnosis of depression, anxiety or bipolar disorder, general CBT receipt prior to the primary psychosis diagnosis date or type of psychosis diagnosis predicted CBTp receipt. RESULTS Of patients with a psychotic disorder, only 8.2% received CBTp. Individuals with at least one depressive symptom recorded, depression symptom severity and 12 out of 15 of the individual depressive symptoms independently predicted CBTp receipt. Female gender, White ethnicity and presence of a comorbid affective disorder or primary schizoaffective diagnosis were independently positively associated with CBTp receipt within the whole sample and the top 25% of mentioned depressive symptoms. CONCLUSIONS Individuals with a psychotic disorder who had recorded depressive symptoms were significantly more likely to receive CBTp sessions, aligning with CBTp guidelines of managing depressive symptoms related to a psychotic experience. However, overall receipt of CBTp is low and more common in certain demographic groups, and needs to be increased.

Porter L, Jones C, Fox A. Reliability of the Calgary depression scale for schizophrenia: A meta-analysis. Schizophr Res 2022; 240:32-45. [PMID: 34920367 DOI: 10.1016/j.schres.2021.11.040] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Revised: 10/17/2021] [Accepted: 11/26/2021] [Indexed: 12/30/2022]
Abstract
BACKGROUND A challenge for clinicians working with individuals diagnosed with schizophrenia is distinguishing depressive symptoms from negative symptoms of schizophrenia. The Calgary Depression Scale for Schizophrenia (CDSS) was developed for this purpose. No review has previously explored its reliability across multiple studies using advanced statistical means. OBJECTIVES This meta-analysis aimed to quantify the CDSS' internal consistency, inter-rater reliability (IRR) and test-retest reliability. METHOD A systematic literature search was conducted to find articles reporting on the CDSS' reliability. Articles were screened against the inclusion and exclusion criteria, with data extracted from 40 studies. Overall meta-analytic effects were calculated, and for internal consistency and IRR coefficients subsequent analyses explored between-study variation. The small test-retest reliability dataset limited analysis. FINDINGS The internal consistency meta-analytic effect was 0.83 (95% CI:0.82-0.84). Higgins I2 indicated an acceptable level of variation between studies' alpha estimates. This suggests all items in the CDSS are measuring the same construct (i.e. symptoms of depression). The IRR meta-analytic effect was 0.88 (95% CI:0.86-0.91), with Higgins I2 indicating high levels of heterogeneity. This was not deemed problematic variance as it is within levels expected for psychometric measures and, therefore, considered acceptable for this literature. This reflects high level of agreement between different raters when using the CDSS on the same client. CONCLUSIONS This review suggests the CDSS has good internal consistency and excellent IRR. Further research will help understand its test-retest reliability.

Feasibility and efficacy of an acceptance and mindfulness-based group intervention for young people with early psychosis (Feel-Good group). Front Psychiatry 2022; 13:943488. [PMID: 36186856 PMCID: PMC9522968 DOI: 10.3389/fpsyt.2022.943488] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2022] [Accepted: 08/22/2022] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Over the last decade, researchers have sought for alternative interventions that have better treatment effects than Cognitive Behavioral Therapy (CBT) when treating psychotic symptoms. Mindfulness-based interventions have been a proposed alternative to CBT, yet research regarding its feasibility, acceptance and effectiveness is lacking when treating individuals with early psychosis in inpatient settings. OBJECTIVE Before conducting a large-scale randomized-controlled trial (RCT), this pilot study evaluated the feasibility and the potential efficacy of a mindfulness-based inpatient group intervention that targets emotion regulation in patients with early psychosis, and thus indirectly improving psychotic symptoms. METHODS A pre-post study was performed. Thirty-six patients with early psychosis treated at the specialized inpatient treatment "Frühinterventions- und Therapiezentrum; FRITZ" (early intervention and therapy center) received eight group therapy sessions. Assessments were performed at baseline, after 8 weeks post treatment and at follow-up after 16 weeks. RESULTS Rates of patients who participated in the study suggests that a mindfulness-based group therapy is highly accepted and feasible for patients with early psychosis being treated in an inpatient ward. Friedman analyses revealed significant changes in the primary outcomes of emotional goal attainment (Goal 1: W = 0.79; Goal 2: W = 0.71) and psychotic symptoms (PANSS-T: W = 0.74). Significant, albeit small, effect sizes were found in patients' self-perception of emotion regulation skills (ERSQ: W = 0.23). DISCUSSION We found favorable findings regarding the feasibility and acceptance of the Feel-Good mindfulness-based intervention. Results of the study provide a basis for an estimation of an adequate sample size for a fully powered RCT that needs to be conducted to test whether Feel-Good is effective in the inpatient treatment of psychotic symptoms for individuals with early psychosis.

Abstract
Comorbid diagnoses are common in youth who are at clinical high-risk (CHR) for developing psychosis, with depression being the most common. The aim of this paper is to examine depression over two years in a large sample of CHR youth who do not make the transition to psychosis, considering both categorical and dimensional ratings of depression severity. The sample consisted of 267 CHR youth who were followed for two years. Based on DSM-IV diagnoses over this time period, 100 CHR individuals never received a diagnosis of depression, 64 individuals continuously met criteria for depression, 92 individuals received a diagnosis of depression at one or more timepoints, and 11 participants had a diagnosis of depression only at 24-months. These groupings were supported by six-monthly ratings on the Calgary Depression Scale. The majority of this sample experienced a major depressive episode on more than one occasion, suggesting that depression and depressive symptoms identify a domain of substantial unmet clinical need. Recommendations are that depression in CHR youth and young adults should be monitored more frequently and that there is a need for clinical trials to address depression systematically in this vulnerable population.

Aberrant computational mechanisms of social learning and decision-making in schizophrenia and borderline personality disorder. PLoS Comput Biol 2020; 16:e1008162. [PMID: 32997653 PMCID: PMC7588082 DOI: 10.1371/journal.pcbi.1008162] [Citation(s) in RCA: 31] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Revised: 10/26/2020] [Accepted: 07/19/2020] [Indexed: 12/13/2022] Open
Abstract
Psychiatric disorders are ubiquitously characterized by debilitating social impairments. These difficulties are thought to emerge from aberrant social inference. In order to elucidate the underlying computational mechanisms, patients diagnosed with major depressive disorder (N = 29), schizophrenia (N = 31), and borderline personality disorder (N = 31) as well as healthy controls (N = 34) performed a probabilistic reward learning task in which participants could learn from social and non-social information. Patients with schizophrenia and borderline personality disorder performed more poorly on the task than healthy controls and patients with major depressive disorder. Broken down by domain, borderline personality disorder patients performed better in the social compared to the non-social domain. In contrast, controls and major depressive disorder patients showed the opposite pattern and schizophrenia patients showed no difference between domains. In effect, borderline personality disorder patients gave up a possible overall performance advantage by concentrating their learning in the social at the expense of the non-social domain. We used computational modeling to assess learning and decision-making parameters estimated for each participant from their behavior. This enabled additional insights into the underlying learning and decision-making mechanisms. Patients with borderline personality disorder showed slower learning from social and non-social information and an exaggerated sensitivity to changes in environmental volatility, both in the non-social and the social domain, but more so in the latter. Regarding decision-making the modeling revealed that compared to controls and major depression patients, patients with borderline personality disorder and schizophrenia showed a stronger reliance on social relative to non-social information when making choices. Depressed patients did not differ significantly from controls in this respect. Overall, our results are consistent with the notion of a general interpersonal hypersensitivity in borderline personality disorder and schizophrenia based on a shared computational mechanism characterized by an over-reliance on beliefs about others in making decisions and by an exaggerated need to make sense of others during learning specifically in borderline personality disorder. People suffering from psychiatric disorders frequently experience difficulties in social interaction, such as an impaired ability to use social signals to build representations of others and use these to guide behavior. Compuational models of learning and decision-making enable the characterization of individual patterns in learning and decision-making mechanisms that may be disorder-specific or disorder-general. We employed this approach to investigate the behavior of healthy participants and patients diagnosed with depression, schizophrenia, and borderline personality disorder while they performed a probabilistic reward learning task which included a social component. Patients with schizophrenia and borderline personality disorder performed more poorly on the task than controls and depressed patients. In addition, patients with borderline personality disorder concentrated their learning efforts more on the social compared to the non-social information. Computational modeling additionally revealed that borderline personality disorder patients showed a reduced flexibility in the weighting of newly obtained social and non-social information when learning about their predictive value. Instead, we found exaggerated learning of the volatility of social and non-social information. Additionally, we found a pattern shared between patients with borderline personality disorder and schizophrenia who both showed an over-reliance on predictions about social information during decision-making. Our modeling therefore provides a computational account of the exaggerated need to make sense of and rely on one’s interpretation of others’ behavior, which is prominent in both disorders.

How anticipatory pleasure and negative beliefs contribute to goal-directed activity in patients with negative symptoms of psychosis. Schizophr Res 2020; 222:429-436. [PMID: 32389616 DOI: 10.1016/j.schres.2020.03.059] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2019] [Revised: 02/16/2020] [Accepted: 03/27/2020] [Indexed: 01/18/2023]
Abstract
Anticipatory pleasure refers to a state of positive affect in anticipation of future events that has been found to motivate goal-directed behavior. Previous research has indicated that patients with negative symptoms of psychosis show reduced goal-directed behavior because 'demotivating beliefs' impede anticipatory pleasure. This study aims to link demotivating beliefs and anticipatory pleasure to patients' motivation in everyday life. Using the Experience Sampling Method, we examined the motivational process of goal-directed activity in the daily lives of 35 patients with negative symptoms and 36 healthy controls. We tested whether the mechanism underlying goal-directed behavior differs between patients and healthy controls and whether demotivating beliefs interfere with goal-directed behavior by impeding anticipatory pleasure. Multilevel analyses revealed that anticipatory pleasure mediated the association between goal-intentions and goal-directed activity in both groups (indirect effects: 24-30%). In the patient group, however, the association between social goal-intentions and anticipatory pleasure was weaker (b = -0.09, SE = 0.05, p ≤ .01, [-0.17;-0.04]) than in the controls, but this was not found for goal-intentions related self-care or recreational activites. Also, demotivating beliefs were more pronounced in the patient sample. (F(1,70) = 72.11, p ≤ .001) and moderated the effect of goal-intentions on anticipatory pleasure for social activities in the whole sample (b = -0.12, SE = 0.05, p ≤ .01, [-0.20;-0.08]). Our results support the assumption that a set of demotivating beliefs prevents patients with negative symptoms from looking forward to social activities and thus provide a possible psychological explanation for the social withdrawal of patients with negative symptoms.

Levels of Structural Integration Mediate the Impact of Metacognition on Functioning in Non-affective Psychosis: Adding a Psychodynamic Perspective to the Metacognitive Approach. Front Psychol 2020; 11:269.

Abstract
Synthetic metacognition is defined by integrative and contextualizing processes of discrete reflexive moments. These processes are supposed to be needed to meet intrapsychic as well as interpersonal challenges and to meaningfully include psychotic experience in a personal life narrative. A substantial body of evidence has linked this phenomenon to psychosocial functioning and treatment options were developed. The concept of synthetic metacognition, measured with the Metacognition Assessment Scale-Abbreviated (MAS-A), rises hope to bridge gaps between therapeutic orientations and shares valuable parallels to modern psychodynamic constructs, especially the 'levels of structural integration' of the Operationalized Psychodynamic Diagnosis (OPD-2). As theoretical distinctions remain, aim of this study was to compare the predictive value of both constructs with regard to psychosocial functioning of patients with non-affective psychoses, measured with the International Classification of Functioning, Disability and Health (MINI-ICF-APP). It was further explored if levels of structural integration (OPD-LSIA) would mediate the impact of metacognition (MAS-A) on function (MINI-ICF-APP). Expert ratings of synthetic metacognition (MAS-A), the OPD-2 'levels of structural integration' axis (OPD-LSIA), psychosocial functioning (MINI-ICF-APP) and assessments of general cognition and symptoms were applied to 100 individuals with non-affective psychoses. Whereas both, MAS-A and OPD-LSIA, significantly predicted MINI-ICF-APP beyond cognition and symptoms, OPD-LSIA explained a higher share of variance and mediated the impact of MAS-A on MINI-ICF-APP. Levels of structural integration, including the quality of internalized object representations and unconscious interpersonal schemas, might therefore be considered as valuable predictors of social functioning and as one therapeutic focus in patients with non-affective psychoses. Structural integration might go beyond and form the base of a person's actual reflexive and metacognitive capabilities. Psychotherapeutic procedures specific for psychoses may promote and challenge a patient's metacognitive capacities, but should equally take the need for maturing structural skills into account. Modern psychodynamic approaches to psychosis are shortly presented, providing concepts and techniques for the implicit regulation of interpersonal experience and aiming at structural integration in this patient group.

Abstract
Numerous cross-sectional studies found psychosis to be associated with less awareness of emotions, a decreased use of adaptive (e.g. reappraisal) and an increased use of maladaptive emotion regulation (ER) strategies (e.g. suppression). In this study, we tested whether state levels of emotion awareness and momentary use of specific ER strategies moderate the link between negative affect at one timepoint (t-1) and paranoia at the next timepoint (t) in a six-day experience sampling study. Individuals with psychotic disorders (n = 71) reported on the presence of paranoia, negative affect, emotion awareness and the use of six ER strategies (reappraisal, acceptance, social sharing, distraction, suppression and rumination) ten times per day. Multilevel regression analysis revealed that higher awareness at t-1 reduced the association of negative affect at t-1 and paranoia at t, whereas rumination had an opposite, amplifying moderation effect. Our results provide novel insight into the conditions under which negative affect translates into delusional beliefs. The finding that emotion awareness and rumination have a relevant role corresponds with current psychological conceptualisations of psychosis and with the attempt to treat delusions by focusing on reducing ruminative thoughts. To investigate the causal effect, treatment trials with a focus on enhancing these components of emotion regulation are needed.

Abstract
Determining depression symptoms in schizophrenic patients is a challenging process because of a degree of similarity between depression symptoms and negative symptoms and the extrapyramidal side effects of neuroleptic drugs, but it is crucial to evaluate and measure depression among patients with schizophrenia for a better clinical outcome. The Calgary Depression Scale for Schizophrenia (CDSS) is a valid and reliable instrument used for the evaluation of depression in schizophrenia. This study aimed to determine the psychometric properties of the Persian version of CDSS in a sample of people with schizophrenia. Clinical interviews were conducted with 95 schizophrenic patients (40 inpatients and 55 outpatients), who were assessed with the Positive and Negative Syndrome Scale (PANSS), Hamilton Depression Rating Scale (HDRS-17 and HDRS-24 items), and the Calgary Depression Rating Scale (CDSS). Then an exploratory factor analysis was conducted to determine correlations between scales, Cronbach's alpha, and cutoff scores. The factor analysis led to the extraction of a unifactorial solution. The CDSS had significant relationships with PANSS Negative and PANSS General. However, it had no significant relationship with PANSS Positive and the PANSS Total. The CDSS also had significant relationships with HDRS-17 and HDRS-24. In addition, Cronbach's alpha of total score, test-retest reliability, and cutoff score were estimated at 0.86, 0.82, and 8 (sensitivity = 0.79 and specificity = 0.84), respectively. The findings support the CDSS unifactorial approach. Results also showed that the CDSS Persian version had acceptable psychometric properties; thus, it could be employed to evaluate depression among schizophrenic patients.

Vargas T, Ahmed AO, Strauss GP, Brandes CM, Walker EF, Buchanan RW, Gold JM, Mittal VA. The latent structure of depressive symptoms across clinical high risk and chronic phases of psychotic illness. Transl Psychiatry 2019; 9:229. [PMID: 31527596 PMCID: PMC6746855 DOI: 10.1038/s41398-019-0563-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2019] [Revised: 05/27/2019] [Accepted: 07/07/2019] [Indexed: 11/21/2022] Open
Abstract
Depressive symptoms are highly prevalent in psychotic populations and result in significant functional impairment. Limited knowledge of whether depressive symptoms are invariant across stages of illness curtails our ability to understand how these relate to illness progression. Clarifying the latent structure of depressive symptoms across stages of illness progression would aid etiological conceptualizations and preventive models. In the present study, one-factor (including all items) and two-factor (depression/hopelessness and guilt/self-depreciation) solutions were specified through confirmatory factor analysis (CFA). Measurement invariance analyses were undertaken across schizophrenia (SCZ; n = 312) and clinical high-risk (CHR; n = 175) groups to estimate whether the same construct is being measured across groups. Clinical correlates of the factors were examined. Results indicated that CHR individuals had a greater proportion of mood disorder diagnoses. Metric invariance held for the one-factor solution, and scalar invariance held for the two-factor solution. Notably, negative symptoms did not correlate with depressive symptoms in the SCZ group, though strong correlations were observed in CHR individuals. Positive symptoms were comparably associated with depressive symptoms in both groups. Results suggest depressive symptoms are more prevalent in CHR individuals. Targeting these symptoms may aid future efforts to identify risk of conversion. Further, some depressive symptoms may be systematically more endorsed in CHR individuals. Separating into depression/hopelessness and guilt/self-depreciation scores may aid comparability across stages of illness progression, though this issue deserves careful attention and future study.

Abstract
To mitigate the often chronic course of schizophrenia and improve functional outcome, researchers are increasingly interested in prodromal states and psychological risk factors that may predict the outbreak of psychotic symptoms, but are also amenable to change. In recent years, depressive symptoms have been proposed as precursors of psychosis and some interventional studies indicate that the amelioration of depressive symptoms and depression-related thinking styles (e.g., worrying) improves positive symptoms, thereby "killing two birds with one stone". Yet, in a prior study, we were unable to find a strong specific predictive role of depression on paranoia over three years, which may have been due to the use of a nonclinical sample with minimal/mild symptom fluctuations. To address this further, in the present study we adopted a similar methodological approach but assessed a large patient sample with a schizophrenia spectrum disorder at three assessment points; baseline (N = 250), 6 weeks later (n = 207, 82.8% retention) and 6 months after baseline (n = 185, 74% retention). Using cross-lagged modeling, we assessed paranoia with the respective items from the Positive and Negative Syndrome Scale (PANSS) and the Psychosis Rating Scales (PSYRATS) delusions subscale. Depression was measured using the Patient Health Questionnaire-9 (PHQ-9) and the Calgary Depression Scale for Schizophrenia (CDSS). We could identify a significant pathway from depression to paranoia from baseline to post (negative association) but not from post to follow-up. Paranoia significantly predicted depressive symptoms for both intervals. Our findings do not refute claims that depression may precede or even predict psychosis, but such a linkage does not seem to be ubiquitous.

Abstract
OBJECTIVE We tested whether people with schizophrenia and prominent expressive negative symptoms (ENS) show reduced facial expressions in face-to-face social interactions and whether this expressive reduction explains negative social evaluations of these persons. METHOD We compared participants with schizophrenia with high ENS (n = 18) with participants with schizophrenia with low ENS (n = 30) and with healthy controls (n = 39). Participants engaged in an affiliative role-play that was coded for the frequency of positive and negative facial expression and rated for social performance skills and willingness for future interactions with the respective role-play partner. RESULTS Participants with schizophrenia with high ENS showed significantly fewer positive facial expressions than those with low ENS and controls and were also rated significantly lower on social performance skills and willingness for future interactions. Participants with schizophrenia with low ENS did not differ from controls on these measures. The group difference in willingness for future interactions was significantly and independently mediated by the reduced positive facial expressions and social performance skills. CONCLUSION Reduced facial expressiveness in schizophrenia is specifically related to ENS and has negative social consequences. These findings highlight the need to develop aetiological models and targeted interventions for ENS and its social consequences.

Abstract
Anhedonia, or the inability to experience pleasure, is commonly observed in schizophrenia. It has been suggested that patients with schizophrenia are unable to predict future pleasurable events, but show intact experience of in-the-moment pleasure. Therefore, the Temporal Experience of Pleasure Scale (TEPS), a self-report measure allowing the assessment of anticipatory and consummatory pleasure, has been developed. To validate the German version of the TEPS, we recruited 59 healthy control participants and 51 patients with schizophrenia or schizoaffective disorder who completed the TEPS as well as a battery of psychometric tests to assess psychopathology, in particular self-rated anhedonia and clinician-rated apathy as well as overall measures of negative symptoms. We found acceptable to good internal consistency and a factor structure comparable to the original version. Scores of the TEPS were related to measures of anhedonia and apathy, but not with other measures of psychopathology. The present results suggest that the German version of the TEPS shows adequate reliability and validity to assess the construct of anhedonia. However, differential aspects of anticipatory and consummatory pleasure should be further investigated in clinical samples.

Abstract
BACKGROUND The recovery framework has found its way into local and national mental health services and policies around the world, especially in English speaking countries. To promote this process, it is necessary to assess personal recovery validly and reliably. The Recovery Assessment Scale (RAS) is the most established measure in recovery research. The aim of the current study is to examine the factor structure of the German version of the RAS (RAS-G). METHODS One hundred and fifty-six German-speaking clients with schizophrenia or schizoaffective disorder from a community mental health service completed the RAS-G plus measures of recovery attitudes, self-stigma, psychotic symptoms, depression, and functioning. A confirmatory factor analysis of the original 24-item RAS version was conducted to examine its factor structure, followed by reliability and validity testing of the extracted factors. RESULTS The CFA yielded five factors capturing 14 items which showed a substantial overlap with the original subscales Personal Confidence and Hope, Goal and Success Orientation, Willingness to Ask for Help, Reliance on Others, and No Domination by Symptoms. The factors demonstrated mean to excellent reliability (0.59-0.89) and satisfactory criterial validity by positive correlations with measures of recovery attitudes and functioning, and negative correlations with measures of self-stigma, and psychotic and depressive symptoms. CONCLUSIONS The study results are discussed in the light of other studies examining the factor structure of the RAS. Overall, they support the use of the RAS-G as a means to promote recovery oriented services, policies, and research in German-speaking countries.

Abstract
Defeatist performance beliefs (DPBs) are associated with the severe impairments in functioning of patients with negative symptoms of schizophrenia. This association has been found to be mediated by amotivation, a core aspect of negative symptoms. Although causality is assumed, longitudinal evidence for this is lacking. The current study aimed to extend previous findings by investigating both cross-sectional and longitudinal associations between DPBs, motivational impairments and functioning in a sample of patients with psychotic disorders (N=58). We hypothesized, that DPBs would be related to functioning in cross-sectional and longitudinal analyses and that this link would be mediated by motivational impairments. Data was assessed at baseline and post-treatment in a trial on the effects of cognitive behavior therapy for psychosis. At baseline, amotivation mediated the association between DPBs and functioning. From baseline to post-treatment, reduction of amotivation was associated with improvement of functioning significantly, whereas reduction of DPBs was unrelated to improvements in functioning or amotivation. The findings suggest that improvement in amotivation accounts for favorable treatment outcomes in regard to functioning but question the causal role of DPBs in negative symptoms and functioning.

Abstract
BACKGROUND Patients with schizophrenia commonly show both depressive and negative symptoms that can differentially affect the prognosis and course of treatment. The Calgary Depression Scale for Schizophrenia (CDSS) was designed to distinguish between depression and negative symptoms in patients with schizophrenia. The purpose of this study is to validate an Arabic version of the CDSS among patients with schizophrenia. METHODS The diagnosis of schizophrenia was confirmed using the Arabic Mini International Neuropsychiatric Interview 6 (MINI 6). A standardized translation back-translation process was adopted. One rater administered the Arabic CDSS to subjects with schizophrenia as well as to a control group who should not have any psychiatric disorder except for depression. Another rater, blinded to the results administered the already validated Arabic version of Beck Depression Inventory-II (BDI-II). RESULTS We recruited 102 patients and 102 controls subjects. The CDSS showed good internal consistency in the active group (Cronbach's alpha = 0.82). The Intraclass Coefficient correlations (ICC) for the inter-rater reliability (n = 21) was 0.90, p<0.05 and test-retest reliability (n = 19) was 0.85, p<0.001. When compared to the BDI-II, the cutoff score of 5 on the Arabic CDSS showed reasonable sensitivity and specificity of 72.75% and 67.95% respectively. CONCLUSIONS The psychometric properties of the Arabic version of CDSS demonstrate that it is a valid tool to assess the depressive symptoms in the Arab patients with schizophrenia.

Predictors for symptom re-exacerbation after targeted stepwise drug discontinuation in first-episode schizophrenia: Results of the first-episode study within the German research network on schizophrenia. Schizophr Res 2016; 170:168-76.

Abstract
BACKGROUND After a first episode in schizophrenia guidelines recommend antipsychotic maintenance treatment (MT) for at least 1year. Recent RCTs on subsequent targeted intermittent treatment (IT) after stepwise drug discontinuation yielded noticeably higher relapse rates than during MT also in first-episode patients. Nevertheless, about 50% of patients remain stable under IT. Given the potential adverse effects of antipsychotics and the preference of many patients to discontinue drugs, valid predictors for the feasibility of IT are urgently needed to support decision making. METHODS Based on a one-year RCT phase comparing MT with IT in first-episode patients after 1year of MT, conducted within the German Research Network on Schizophrenia (GRNS), predictors for deterioration under IT in 19 feasible patients were identified by logistic regression analysis. RESULTS Deterioration occurred in 10 patients (52.6%). Univariate analyses indicated a lower PANSS positive score after acute treatment as well as after one year of MT as significant predictors; in multivariate logistic regression, in addition to the lower PANSS positive score after acute treatment, reaching enduring remission and having had a deterioration both during MT evolved as significant predictors and indicate a higher risk for deterioration. CONCLUSIONS Although limited by the small sample size, our findings suggest that patients who show a favorable response and full and enduring symptom remission during antipsychotic treatment, as well as those with marked deterioration despite MT should rather be recommended to remain on treatment because they are at higher risk for symptom re-exacerbation after (stepwise) drug discontinuation.

Abstract
Dysfunctional patterns of activation in brain reward networks have been suggested as a core element in the pathophysiology of schizophrenia. However, it remains unclear whether this dysfunction is specific to schizophrenia or can be continuously observed across persons with different levels of nonclinical and clinical symptom expression. Therefore, we sought to investigate whether the pattern of reward system dysfunction is consistent with a dimensional or categorical model of psychosis-like symptom expression. 23 patients with schizophrenia and 37 healthy control participants with varying levels of psychosis-like symptoms, separated into 3 groups of low, medium, and high symptom expression underwent event-related functional magnetic resonance imaging while performing a Cued Reinforcement Reaction Time task. We observed lower activation in the ventral striatum during the expectation of high vs no reward to be associated with higher symptom expression across all participants. No significant difference between patients with schizophrenia and healthy participants with high symptom expression was found. However, connectivity between the ventral striatum and the medial orbitofrontal cortex was specifically reduced in patients with schizophrenia. Dysfunctional local activation of the ventral striatum depends less on diagnostic category than on the degree of symptom expression, therefore showing a pattern consistent with a psychosis continuum. In contrast, aberrant connectivity in the reward system is specific to patients with schizophrenia, thereby supporting a categorical view. Thus, the results of the present study provide evidence for both continuous and discontinuous neural substrates of symptom expression across patients with schizophrenia and the general population.

Abstract
Concept and design of an independent scientific evaluation of different pathways of care for schizophrenia patients in Germany with respect to effectiveness and efficiency are presented. In this prospective, observational study, schizophrenia patients receiving an integrated care treatment, the intervention group (IG), are compared with patients under routine care conditions treated by the same physician (first control group, CG 1). A second control group (CG 2) of patients treated by office-based psychiatrists not participating in the integrated care program will be recruited and their data compared with the two other groups. The total amount of psychiatric hospital days after 12 months is defined as primary outcome parameter. Secondary outcome parameters comprise the frequency of psychiatric inpatient readmissions, severity of schizophrenia symptoms, remission rates and quality of life. Patients undergo assessments at baseline, month 6 and 12 using standardized and experimental questionnaires. Routine data of a regional German social health insurance fund complement information on included patients. Additionally, a cost-effectiveness and cost-utility analysis will be performed. Until now, 137 psychiatrists included 980 patients in the integrated care project in Lower Saxony, Germany, and 47 psychiatrists (IG and both CGs) are willing to participate in the independent evaluation. For the first time, a prospective observational controlled evaluation study of a countrywide integrated care project planning to recruit 500 schizophrenia patients has started using comprehensive assessments as well as routine data of a social health insurance fund.

Abstract
Motivational deficits (avolition and anhedonia) have historically been considered important negative symptoms of schizophrenia (SZ). Numerous studies have attempted to identify the neural substrates of avolition and anhedonia in schizophrenia , but these studies have not produced much agreement. Deficits in various aspects of reinforcement processing have been observed in individuals with schizophrenia, but it is not exactly clear which of these deficits actually engender motivational impairments in SZ. The purpose of this chapter is to examine how various reinforcement-related behavioral and neural signals could contribute to motivational impairments in both schizophrenia and psychiatric illness, in general. In particular, we describe different aspects of the concept of expected value (EV), such as the distinction between the EV of stimuli and the expected value of actions, the acquisition of value versus the estimation of value, and the discounting of value as a consequence of time or effort required. We conclude that avolition and anhedonia in SZ are most commonly tied to aberrant signals for expected value, in the context of learning. We discuss implications for further research on the neural substrates of motivational impairments in psychiatric illness.

Abstract
UNLABELLED This pilot study aimed to evaluate the feasibility of an assessor-blind, randomised controlled trial of psychodynamic art therapy for the treatment of patients with schizophrenia, and to generate preliminary data on the efficacy of this intervention during acute psychotic episodes. Fifty-eight inpatients with DSM-diagnoses of schizophrenia were randomised to either 12 twice-weekly sessions of psychodynamic group art therapy plus treatment as usual or to standard treatment alone. Primary outcome criteria were positive and negative psychotic and depressive symptoms as well as global assessment of functioning. Secondary outcomes were mentalising function, estimated with the Reading the mind in the eyes test and the Levels of emotional awareness scale, self-efficacy, locus of control, quality of life and satisfaction with care. Assessments were made at baseline, at post-treatment and at 12 weeks' follow-up. At 12 weeks, 55% of patients randomised to art therapy, and 66% of patients receiving treatment as usual were examined. In the per-protocol sample, art therapy was associated with a significantly greater mean reduction of positive symptoms and improved psychosocial functioning at post-treatment and follow-up, and with a greater mean reduction of negative symptoms at follow-up compared to standard treatment. The significant reduction of positive symptoms at post-treatment was maintained in an attempted intention-to-treat analysis. There were no group differences regarding depressive symptoms. Of secondary outcome parameters, patients in the art therapy group showed a significant improvement in levels of emotional awareness, and particularly in their ability to reflect about others' emotional mental states. This is one of the first randomised controlled trials on psychodynamic group art therapy for patients with acute psychotic episodes receiving hospital treatment. Results prove the feasibility of trials on art therapy during acute psychotic episodes and justify further research to substantiate preliminary positive results regarding symptom reduction and the recovery of mentalising function. TRIAL REGISTRATION ClinicalTrials.gov NCT01622166.

Abstract
Theoretical models postulate an important role of attributional style (AS) in the formation and maintenance of persecutory delusions and other positive symptoms of schizophrenia. However, current research has gathered conflicting findings. In a cross-sectional design, patients with persistent positive symptoms of schizophrenia (n = 258) and healthy controls (n = 51) completed a revised version of the Internal, Personal and Situational Attributions Questionnaire (IPSAQ-R) and assessments of psychopathology. In comparison to controls, neither patients with schizophrenia in general nor patients with persecutory delusions (n = 142) in particular presented an externalizing and personalizing AS. Rather, both groups showed a "self-blaming" AS and attributed negative events more toward themselves. Persecutory delusions were independently predicted by a personalizing bias for negative events (beta = 0.197, P = .001) and by depression (beta = 0.152, P = .013), but only 5% of the variance in persecutory delusions could be explained. Cluster analysis of IPSAQ-R scores identified a "personalizing" (n = 70) and a "self-blaming" subgroup (n = 188), with the former showing slightly more pronounced persecutory delusions (P = .021). Results indicate that patients with schizophrenia and patients with persecutory delusions both mostly blamed themselves for negative events. Nevertheless, still a subgroup of patients could be identified who presented a more pronounced personalizing bias and more severe persecutory delusions. Thus, AS in patients with schizophrenia might be less stable but more determined by individual and situational characteristics that need further elucidation.

Is living with psychosis demoralizing? Insight, self-stigma, and clinical outcome among people with schizophrenia across 1 year. J Nerv Ment Dis 2014; 202:521-9.

Abstract
Lack of insight is a major target in the treatment of schizophrenia. However, insight may have undesirable effects on self-concept and motivation that can hinder recovery. This study aimed to examine the link between insight, self-stigma, and demoralization as predictors of symptoms and functioning. Insight, self-stigma, depressive and psychotic symptoms, and functioning were assessed among 133 outpatients with schizophrenia at baseline and 12 months later. The data were analyzed by hierarchical multiple linear regressions. More insight at baseline and an increase in self-stigma over 12 months predicted more demoralization at follow-up. Insight at baseline was not associated with any outcome variable, but self-stigma at baseline was related to poorer functioning and more positive symptoms at follow-up. More demoralization at baseline predicted poorer functioning 12 months later. Demoralization did not mediate the relationship between self-stigma at baseline and functioning after 1 year. Given the decisive role of self-stigma regarding recovery from schizophrenia, dysfunctional beliefs related to illness and the self should be addressed in treatment. Different psychotherapeutical approaches are discussed.

Abstract
This study investigates the predictors of outcome in a secondary analysis of dropout and completer data from a randomized controlled effectiveness trial comparing CBTp to a wait-list group (Lincoln et al., 2012). Eighty patients with DSM-IV psychotic disorders seeking outpatient treatment were included. Predictors were assessed at baseline. Symptom outcome was assessed at post-treatment and at 1-year follow-up. The predictor×group interactions indicate that a longer duration of disorder predicted less improvement in negative symptoms in the CBTp but not in the wait-list group whereas jumping-to-conclusions was associated with poorer outcome only in the wait-list group. There were no CBTp specific predictors of improvement in positive symptoms. However, in the combined sample (immediate CBTp+the delayed CBTp group) baseline variables predicted significant amounts of positive and negative symptom variance at post-therapy and 1-year follow-up after controlling for pre-treatment symptoms. Lack of insight and low social functioning were the main predictors of drop-out, contributing to a prediction accuracy of 87%. The findings indicate that higher baseline symptom severity, poorer functioning, neurocognitive deficits, reasoning biases and comorbidity pose no barrier to improvement during CBTp. However, in line with previous predictor-research, the findings imply that patients need to receive treatment earlier.

Abstract
Assessment of depression in individuals who are considered to be at clinical high risk (CHR) for psychosis is important as high rates of depression have been reported in CHR individuals. The Calgary Depression Scale (CDSS) is the most widely used scale for assessing depression in schizophrenia. It has excellent psychometric properties, internal consistency, inter-rater reliability, sensitivity, specificity, and discriminant and convergent validity. The aim of this study was to test the reliability and validity of the CDSS in a sample of youth at CHR for psychosis. Participants were assessed for depression, presence of axis 1 mood disorders, and prodromal symptoms using the CDSS, the Structured Clinical Interview for DSM-IV Disorders (SCID-1), and the Scale of Prodromal Symptoms (SOPS). The CDSS total score as well as all individual items, except "guilty ideas of reference," were significantly associated with the presence of a major depressive disorder. Significant correlations were observed between CDSS total score and the dysphoric mood item on the SOPS. There was some evidence of overlap between the CDSS and both attenuated positive symptoms and negative symptoms as assessed by the SOPS. It is concluded that CDSS is a reliable scale suitable for assessing depression in individuals considered to be at CHR for psychosis.

Abstract
OBJECTIVE Full and sustained symptom remission is a major treatment objective after a first-episode in schizophrenia. Findings regarding differences in remission between first- and second-generation antipsychotics are inconclusive. This study aimed to provide rates and predictors of remission in first-episode schizophrenia and to identify symptoms that prevent remission. METHODS Prevalence rates of "symptomatic remission" (symptom criteria only) and "enduring remission" (symptom and 6-month time criteria), defined according to Andreasen et al. (2005), were determined in first-episode patients participating in a RCT by the German Research Network on Schizophrenia (GRNS) that compared post-acute, 1-year maintenance treatment with risperidone or haloperidol. Respective predictors at baseline were identified by logistic and Cox regression analysis. RESULTS Prevalence rates were 91.5% for symptomatic remission (n=152/166 eligible patients) and 58.6% for enduring remission (n=65 of 111 patients who continued for at least 6 months; 39.2% of all 166 patients included), with no significant differences between risperidone and haloperidol in either type of remission. Enduring remission often was not reached because of negative symptoms: After 6 months, 40.5% of the patients had at least 1 negative symptom, whereas only 10.8% of the patients had "persisting" positive symptoms. Of the different predictors identified in univariate analyses, (lower) negative symptoms and participating in standardized psychological treatment remained significant in multivariate (stepwise forward) analyses for enduring remission. CONCLUSIONS By far most of the first-episode patients reached a temporary state of full symptomatic remission within 1 year of antipsychotic treatment. However, only about 50% achieved sustained, enduring remission. Negative symptoms are still a major treatment obstacle to enduring remission in schizophrenia.

Abstract
Nicotine has been proposed to be a cognitive enhancer, particularly in schizophrenia patients. So far, the published studies of nicotine effects on antisaccade performance in schizophrenia patients only tested participants who were deprived smokers. Thus, we aimed to test both smoking and non-smoking patients as well as healthy controls in order to extend previous findings. Moreover, we employed a paradigm using standard and delayed trials. We hypothesized that, if nicotine is a genuine cognitive enhancer, its administration would improve antisaccade performance both in smoking and non-smoking participants. A total of 22 patients with schizophrenia (12 smokers and 10 non-smokers) and 26 controls (14 smokers and 12 non-smokers) completed the study. The effects of a nicotine patch (14 mg for smokers, 7 mg for non-smokers) on antisaccade performance were tested in a randomized, double-blind, placebo-controlled, cross-over trial. Schizophrenia patients made significantly more antisaccade errors than controls (p = 0.03). Both patients and controls made fewer antisaccade errors in the delayed trials than in the standard trials (p < 0.0001). Nicotine significantly reduced antisaccade error rate in the standard trials, but not in the delayed trials (p = 0.02). Smoking status did not influence the nicotine effect on antisaccade error rate (p = 0.10) indicating an equal procognitive effect of nicotine in smokers and non-smokers. Overall the present findings indicate that beneficial effects of nicotine on antisaccade performance are not confined to smoking schizophrenia patients. Instead, the findings likely represent genuine nicotine-induced enhancement of cognitive performance.

The extent and origin of discordance between self- and observer-rated depression in patients with psychosis. Psychiatry Res 2013; 205:247-52.

Abstract
It is assumed that patients with psychosis have difficulties indicating clinical symptoms accurately in self-reported measures. The present study investigated the ability of self-rating scales to detect symptoms of depression in patients with psychosis and aimed at identifying demographic, clinical and neurocognitive factors that predict the discordance between self-ratings and observer ratings. Inpatients and outpatients with psychosis (n=118) were assessed for depression by applying two observer rating and two self-rating scales. We found reasonable correlation scores between the ratings by patients and observers (range: r=0.50-0.57). In half of the patients (49.2%) the self-ratings corresponded well with the ratings of clinicians. Patients who rated their depressive symptoms as less severe than the clinicians demonstrated more negative symptoms such as blunted affect and poor affective rapport. Patients who rated their depression symptoms as being more severe were characterized by more self-reported general psychopathology. The concordance rates indicate that self-ratings of depression can be a valid additional tool in clinical assessment of patients with psychosis. However, clinicians should be attentive to the fact that some patients might have a general tendency to over-report symptoms and that patients with negative symptoms tend to be rated as more depressed in observer ratings compared with self-assessments.

Abstract
BACKGROUND Depressive symptoms require accurate recognition and monitoring in clinical practice of patients with schizophrenia. Depression instruments developed for use in depressed patients may not discriminate depressive symptoms from negative psychotic symptoms. OBJECTIVE We reviewed depression instruments on their reliability and validity in patients with schizophrenia. METHODOLOGY A systematic literature search was carried out in three electronic databases. Psychometric properties were extracted for those instruments of which reliability, divergent, concurrent and predictive validity were reported in one or more publications. RESULTS Forty-eight publications described the reliability and validity of six depression instruments in patients with schizophrenia. The only self-report was the Beck Depression Inventory (BDI). The Brief Psychiatric Rating Scale-Depression subscale (BPRS-D), Positive and Negative Syndrome Scale-Depression subscale (PANSS-D), Hamilton Rating Scale for Depression (HAMD), Montgomery Asberg Depression Rating Scale (MADRS) and Calgary Depression Scale for Schizophrenia (CDSS) were clinician rated. All instruments were reliable for the measurement of depressive symptoms in patients with schizophrenia. The CDSS most accurately differentiated depressive symptoms from other symptoms of schizophrenia (divergent validity), correlated well with other depression instruments (concurrent validity), and was least likely to miss cases of depression or misdiagnose depression (predictive validity). CONCLUSIONS We would recommend to use the CDSS for the measurement of depressive symptoms in research and in daily clinical practice of patients with schizophrenia. A valid self-report instrument is to be developed for the use in clinical practice.

Abstract
BACKGROUND Assessing attachment style in people with schizophrenia may be important to identify a risk factor in building a strong therapeutic relationship and so indirectly to understand the development of mal-compliance as one of the major obstacles in the treatment of schizophrenia. AIMS The present study analysed the psychometric properties of the German version of the Psychosis Attachment Measure (PAM), which assesses avoidant and anxious attachment style. METHODS A sample of 127 patients suffering from chronic schizophrenia or schizoaffective disorder participated in this study. In testing discriminant validity, we assessed psychopathology, depression, therapeutic relationship and service engagement. Internal consistency, test-retest reliability and factor structure were analysed. RESULTS The German version of PAM exhibited acceptable to good internal and test-retest reliabilities and the two-factor structure of the English version could be replicated. Avoidant attachment style was related to higher levels of positive symptoms and to a poorer therapeutic relationship. In the context of external validation, a regression analysis revealed that a poor therapeutic relationship correlated with avoidant attachment style, independent of anxious attachment style and depressive symptoms. Anxious attachment was associated with higher treatment adherence. Both insecure attachment styles (avoidant and anxious) were found to be correlated with higher levels of depression, but only attachment anxiety had an independent predictive value for self-reported depression in regression analysis. CONCLUSIONS The German version of PAM displayed satisfactory psychometric properties and seems to be a reliable measure for assessing attachment style in individuals with schizophrenia. Validation of PAM led to the finding that only the avoidant attachment style might be a risk factor when building a strong therapeutic relationship in schizophrenia. In future studies, other factors influencing therapeutic relationship should be taken into account. Anxious attachment style may be a risk factor for depression, but it also has an enhancing effect on treatment adherence.

Abstract
BACKGROUND Paradoxically, insight is associated with positive outcomes, such as better treatment adherence and recovery, and negative outcomes, such as depression, hopelessness, low self-esteem, and quality of life. Self-stigma as a moderating variable can be decisive whether more insight leads to better or worse outcome. On the other hand, self-stigma can act as a mediator between insight and outcomes. We therefore examined self-stigma both as a moderator and a mediator. METHODS Insight, self-stigma, demoralization, symptoms, and functioning were assessed among 145 outpatients with schizophrenia spectrum disorders using questionnaires and structured interviews. Structural equation modeling was used to analyze the cross-sectional data. RESULTS Results confirmed self-stigma as a moderator: The association of insight and demoralization was stronger as self-stigma increased. Self-stigma also partially mediated the positive relationship between insight and demoralization. Moreover, demoralization fully mediated the adverse associations of self-stigma with psychotic symptoms and global functioning. DISCUSSION Given the decisive role of self-stigma regarding the detrimental consequences of insight, interventions should address self-stigma, particularly if psychoeducational or other interventions have increased insight. Therapeutic implications for changes of dysfunctional beliefs related to illness and self and change of self-concept in the context of recovery at the level of narrative identity are discussed.

Abstract
BACKGROUND Because the mere definition of insight from the therapist's viewpoint may not be sufficient to identify treatment targets for adherence enhancement, we need assessment strategies which are more sensitive to the patient's perspective. Illness perception (IP), defined as the beliefs a patient holds about his/her health problems, has been shown to affect coping in the context of a physical or mental illness, e.g. compliance behaviour. To assess IP in people diagnosed with schizophrenia, the Illness Perception Questionnaire for Schizophrenia (IPQS) was developed. The aim of the present study was to analyse the psychometric properties of the German version of the IPQS. SAMPLING AND METHODS The study sample consisted of 128 German-speaking outpatients suffering from chronic schizophrenia or schizoaffective disorder. To achieve comparability with the validation of the English scale version, the same constructs were assessed: psychopathology, depression, and beliefs about medication. Furthermore, insight into one's illness was assessed. Internal consistency, test-retest reliability and construct validity including convergent and discriminant validity were analysed. RESULTS Five of eight IPQS subscales were found to be internally reliable and all subscales demonstrated high stability over time. Correlations with validity measures indicated that the subscales assess dimensions of a construct, which is distinct from psychopathology, depression, beliefs about medication and insight, except for the Identity subscale which substantially overlapped with measures of insight. CONCLUSIONS The German version of the IPQS is an essentially reliable and valid measure of IP for German-speaking people with a schizophrenia spectrum disorder. This may encourage its usage in further studies investigating the impact of subjective beliefs about mental health problems on outcome and recovery in schizophrenia.

Abstract
Attitudes toward medication are important predictors of medication adherence in schizophrenia. However, monitoring their strength and influence in clinical settings is challenged by the absence of assessments separating them from adherence and subjective response and distinguishing between attitudes toward pharmacotherapy in general and antipsychotic medications. This study examined the applicability of the Beliefs about Medication Questionnaire (BMQ) in outpatients with schizophrenia (N = 131). Confirmatory factor analysis (CFA) could not support the original four-factor structure. A subsequent exploratory factor analysis revealed the factors Antipsychotics Necessity, Antipsychotics Concern, and Pharmacotherapy Distrust were supported by an acceptable fit of a completing CFA. These subscales have satisfactory internal reliability, test-retest reliability, and local fit indices. Modest correlations with insight and illness perception indicate construct validity. Criterion validity was supported by a significantly higher medication adherence of accepting patients compared with skeptical patients. The BMQ is a psychometrically sound and valid measure of attitudes toward medication in outpatients with schizophrenia.

Abstract
This paper addresses the relationships between certain attributes of knowledge, knowledge management styles and organizational performance. From an extensive study of the literature, an innovative knowledge space (K-Space) model of organizational knowledge was developed as the first stage of the research. This led to the identification of four knowledge management styles and a framework that relates these styles to knowledge creation and improved organizational performance. A survey instrument was developed to measure the constructs contributing to the relationships in this framework and mailed to 338 organizations in different Australian industries. The results confirm that an organization can improve its performance through better management of its knowledge capabilities. Using a MANOVA analysis, the four knowledge management styles were found to be deployed in significantly different ways by organizations in different industry types. There is, however, in all organizations a particular benefit from deploying a balance of knowledge management styles which combine the human and technology perspectives. The findings of the study also demonstrate that the K-Space model provides a basis for a new way of conceptualising knowledge creation processes within organizations.

Can delusions be self-assessed? Concordance between self- and observer-rated delusions in schizophrenia. Psychiatry Res 2010; 178:249-54.

Abstract
Several multi-dimensional self-report scales have been developed to assess delusional ideation in the general population. However, self-ratings of positive symptoms in patients with psychosis are often considered unreliable due to neuro-cognitive disturbance and lack of insight. This study tested associations of self- and observer-rated delusions as well as factors associated with discrepancies. Observer-rated delusions were assessed in 80 in- and outpatients with schizophrenia spectrum disorders by trained raters with the Positive and Negative Syndrome Scale. Self-rated delusions were assessed with the Peters et al. Delusions Inventory and the Paranoia Checklist. Correlations between self- and observer-rated overall delusions ranged from 0.49 to 0.57. Associations between specific delusions of persecution and grandiosity were moderate but unique. Good concordance of ratings was not restricted to outpatients or patients with fewer positive symptoms. Patients with lower self- than observer ratings of delusions were characterised by fewer years of education, lower functioning, more negative symptoms and less insight. The results indicate that patients can reliably provide information with regard to the presence and type of delusional beliefs. Thus, patient ratings are a valid additional source of diagnostic information.

Abstract
INTRODUCTION There is substantial evidence for Theory of Mind (ToM) deficits in patients with schizophrenia. Many psychotic symptoms may best be understood in light of an impaired capacity to infer one's own and other persons' mental states and to relate those to executing behavior. The aim of our study was to investigate ToM abilities in first-episode schizophrenia patients and to analyze them in relation to neuropsychological and psychopathological functioning. MATERIALS AND METHODS A modified Moving Shapes paradigm was used to assess ToM abilities in 23 first-episode patients with schizophrenia and 23 matched healthy controls. Participants had to describe animated triangles which moved (1) randomly, (2) goal-directed, or (3) in complex, socially interactive ways (ToM video sequences). Neuropsychological functioning, psychopathology, autistic and alexithymic features as well as empathetic abilities were correlated with ToM performance. RESULTS Compared to healthy controls, first-episode schizophrenia patients gave more incorrect descriptions and used less ToM-related vocabulary when responding to socially complex ToM video sequences. No group differences were revealed for videos with random movements. ToM abilities correlated significantly with positive symptoms, reasoning, verbal memory performance and verbal IQ, but not with empathetic abilities or autistic and alexithymic features. When controlling for reasoning, verbal memory performance and verbal IQ, the correctness of video descriptions was still significantly worse in schizophrenia patients. DISCUSSION The results of our study in first-episode schizophrenia patients underline recent findings on ToM deficits in the early course of schizophrenia. Only a moderate influence of neurocognitive deficits on ToM performance was observed. Impairment in ToM abilities seems to be predominantly independent of clinical state, alexithymia and empathy.

Neural correlates of reward processing in schizophrenia--relationship to apathy and depression. Schizophr Res 2010; 118:154-61. [PMID: 20005675 DOI: 10.1016/j.schres.2009.11.007] [Citation(s) in RCA: 168] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2009] [Revised: 11/03/2009] [Accepted: 11/15/2009] [Indexed: 11/22/2022]
Abstract
The present study employs a new framework to categorise the heterogeneous findings on the relationship between impaired reward processing and negative and affective symptoms of schizophrenia. Based on previous behavioural and neuroimaging studies we postulate that "wanting" (i.e. anticipation) of a reward is specifically related to apathy, whereas "liking" (i.e. hedonic impact) is related to anhedonia and depression--symptoms commonly observed in schizophrenia. Fifteen patients with schizophrenia or schizoaffective disorder treated with atypical antipsychotic drugs and fifteen healthy controls performed a probabilistic monetary incentive delay task while undergoing functional magnetic resonance imaging. At the group level we found no significant differences between patients and controls in neural activation during anticipation or receipt of a reward. However, in patients with schizophrenia specific relationships between ventral-striatal activation and symptoms were observed. Ventral-striatal activation during reward anticipation was negatively correlated with apathy, while activation during receipt of reward was negatively correlated with severity of depressive symptoms. These results suggest that the link between negative symptoms and reward anticipation might specifically relate to apathy, i.e. a lack of motivation and drive. Impaired hedonic reward processing might contribute to the development of depressive symptoms in patients with schizophrenia, but it is not directly associated with self-rated anhedonia. These results indicate the necessity of more specifically differentiating negative and affective symptoms in schizophrenia in order to understand the role of the reward system in their pathogenesis.
