Abstract
AIM Cognitive disturbances typically precede the onset of overt psychotic symptoms and represent a neurobiological marker for psychosis risk that is also associated with poor functional outcomes. The Measure of Insight into Cognition-Self Report (MIC-SR) is a widely used 12-item questionnaire that assesses the perceived frequency of cognitive impairment in the domains of executing functioning, attention, and memory. However, the MIC-SR is not available in Spanish, one of the most widely spoken languages worldwide. The present study aimed to provide a Spanish version of the MIC-SR and examine its psychometric properties in psychosis-risk and non-clinical Mexican young adults. METHODS The sample comprised 621 participants who completed a battery of self-report measures via an online survey. Of the participants, 478 were non-clinical, and 143 met the screening criteria for a clinical high-risk for psychosis (CHR-positive). RESULTS Confirmatory Factor Analyses supported a one-factor model, consistent with the findings for the original MIC-SR. The results showed adequate fit indices for the general model and the independent models for both groups, with high Cronbach's alpha coefficients. Furthermore, the CHR-positive group showed more frequent subjective cognitive problems on each of the 12 items, higher total scores, and higher average frequency than the non-clinical group. CONCLUSION To our knowledge, this is the first translation of the MIC-SR into Spanish. Using the MIC-SR at the CHR stage may contribute to our understanding of cognitive processes associated with the onset of a psychotic disorder and provide valuable information in the context of detection and early intervention efforts.

Performance-based attentional control, but not self-reported attentional control, predicts changes in depressive symptoms in short-term psychotherapy. Behav Res Ther 2024; 173:104476. [PMID: 38199180 DOI: 10.1016/j.brat.2024.104476] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2023] [Revised: 12/18/2023] [Accepted: 01/03/2024] [Indexed: 01/12/2024]
Abstract
OBJECTIVE Although impairments in attentional control are pervasive across psychopathology, there is substantial individual differences. In the current study, we examined whether individual differences in self-reported and performance-based measures of attentional control predict changes in depressive symptoms and well-being in a diagnostically diverse sample of patients attending a CBT-based partial hospital program. METHOD Participants were 89 patients (56.2% men, 75.3% non-Hispanic White). At baseline, patients completed the self-reported Attentional Control Scale and the Rapid Serial Visual Presentation task (RSVP), a behavioral measure of attentional control. Depressive symptoms were assessed daily using the Patient Health Questionnaire and well-being was assessed using the Mental Health Continuum Short Form. RESULTS On average, greater self-reported attentional control was significantly associated with lower depressive symptoms, β = -0.49, t(52) = 4.84, p < .001, 95% CIs [-0.69, -0.29], and greater well-being, β = 0.45, t(53) = 3.90, p < .001, 95% CIs [0.22, 0.67]. More accurate task-based performance was associated with a decline in depressive symptoms over time, β = -0.02, t(32) = 2.50, p = .02, 95% CIs [-0.04, -0.01]. Neither self-reported nor performance-based measures of attentional control predicted changes in well-being. Finally, exploratory analyses suggest that depressive symptoms also improved over time for individuals who underestimated self-reported attentional control abilities relative to task-based performance, β = -0.19, t(32) = 2.23, p = .03, 95% CIs [-0.36, -0.02]. CONCLUSIONS Results suggest that performance-based attentional control may be an important target for assessment and intervention, as well as a potential mechanism underlying risk and recovery.

Abstract
BACKGROUND An important aspect of recovery in schizophrenia relates to one's subjective, lived experience. Self-report is a subjective measurement method with yet-uncertain utility in the assessment of functioning among individuals diagnosed with schizophrenia-spectrum disorder. No review to date has comprehensively synthesized existing research to evaluate the degree of correspondence, or lack thereof, between subjective and objective assessments of cognitive and everyday functioning, nor how extant data can inform the use of self-reported information in treatment and research. METHODS A systematic review was completed to provide a broad perspective of the literature on this topic. Relevant manuscripts were identified via a search strategy using key terms in PubMed and PsycINFO and a review of manuscript bibliographies. Twenty-six studies met the inclusion criteria. RESULTS These studies show minimal to modest associations between subjective assessments of cognition and everyday functioning and objective assessments of these domains, including informant reports and neuropsychological and behavioral measures. Individuals with schizophrenia appear to overestimate their functioning when compared to objective measures. Depression and greater cognitive ability tend to predict greater correspondence between subjective and objective assessments of cognition and everyday functioning. DISCUSSION This review discusses how we might understand the low correspondence between subjective and objective measures of functioning and provides recommendations for using and eliciting self-reported information in the pursuit of recovery-centered practices.

Abstract
A network of early psychosis-specific intervention programs at the University of Montreal in Montreal, Quebec, Canada, conducted a longitudinal naturalistic five-year study at two Urban Early Intervention Services (EIS). In this study, 198 patients were recruited based on inclusion/exclusion criteria and agreed to participate. Our objectives were to assess the subjective cognition complaints of schizophrenic patients assessed by Subjective Scale to Investigate Cognition in Schizophrenia (SSTICS) in their first-episode psychosis (FEP) in relation to their general characteristics. We also wanted to assess whether there are sex-based differences in the subjective cognitive complaints, as well as differences in cognitive complaints among patients who use alcohol in comparison to those who are abstainers. Additionally, we wanted to monitor the changes in the subjective complaints progress for a period of five years follow-up. Our findings showed that although women expressed more cognitive complaints than men [mean (SD) SSTICS, 28.2 (13.7) for women and 24.7 (13.2) for men], this difference was not statistically significant (r = −0.190, 95 % CI, −0. 435 to 0. 097). We also found that abstainers complained more about their cognition than alcohol consumers [mean (SD) SSTICS, 27.9 (13.4) for abstainers and 23.7 (12.9) for consumers], a difference which was statistically significant (r = −0.166, 95 % CI, −0. 307 to −0.014). Our findings showed a drop in the average score of SSTICS through study follow-up time among FEP patients. In conclusion, we suggest that if we want to set up a good cognitive remediation program, it is useful to start with the patients' demands. This demand can follow the patients' complaints. Further investigations are needed in order to propose different approaches between alcohol users and abstinent patients concerning responding to their cognitive complaints.

Abstract
Introduction: Relationships between subjective cognitive functioning (SCF), objective cognitive functioning (OCF), and depressive symptoms are poorly understood in treatment-resistant psychosis (TRP). This study (a) compares SCF in TRP using positively and negatively worded scales, (b) assess these scales' accuracy, and (c) explores the association between these scales and depressive symptoms. We hypothesised that both SCF scales would be highly correlated, minimally associated with OCF, and similarly associated with depressive symptoms. Methods: Archival clinical data from 52 TRP inpatients was utilised. OCF composite scores were derived from a broad neuropsychological battery. SCF was assessed using the norm-referenced PROMIS 2.0 Cognitive Abilities (positively worded) and Concerns (negatively worded) subscales. A depressive symptom score was derived from the Positive and Negative Syndrome Scale. Results: SCF ratings were higher in patients than OCF. There was a small but significant correlation between PROMIS subscales (r = .30). Neither PROMIS subscale was associated with OCF (r = -.11, r = .01). Depressive symptoms were correlated with the positively (r = -.29) but not negatively worded scale (r = -.13). Conclusion: Individuals with TRP inaccurately rate their cognitive functioning and tend to overestimate their ability. Positively and negatively worded SCF scales associate variably with depressive symptoms, indicating they may not be used interchangeably in TRP.

Abstract
BACKGROUND Executive functioning is essential to daily life and severely impaired in schizophrenia and psychosis risk syndromes. Goal Management Training (GMT) is a theoretically founded, empirically supported, metacognitive strategy training program designed to improve executive functioning. METHODS A randomized controlled parallel group trial compared GMT with treatment as usual among 81 participants (GMT, n = 39 versus Wait List Controls, n = 42) recruited from an early intervention for psychosis setting. Computer generated random allocation was performed by someone independent from the study team and raters post-intervention were unaware of allocation. The primary objective was to assess the impact of GMT administered in small groups for 5 weeks on executive functioning. The secondary objective was to explore the potential of the intervention in influencing daily life functioning and clinical symptoms. RESULTS GMT improved self-reported executive functioning, measured with the Behavior Rating Inventory of Executive Function - Adult version (BRIEF-A), significantly more than treatment as usual. A linear mixed model for repeated measures, including all partial data according to the principle of intention to treat, showed a significant group x time interaction effect assessed immediately after intervention (post-test) and 6 months after intervention (follow-up), F = 8.40, p .005, r .37. Improvement occurred in both groups in objective executive functioning as measured by neuropsychological tests, functional capacity, daily life functioning and symptoms of psychosis rated by clinicians. Self-reported clinical symptoms measured with the Symptoms Check List (SCL-10) improved significantly more after GMT than after treatment as usual, F = 5.78, p .019, r .29. Two participants withdrew due to strenuous testing and one due to adverse effects. CONCLUSIONS GMT had clinically reliable and lasting effects on subjective executive function. The intervention is a valuable addition to available treatment with considerable gains at low cost. TRIAL REGISTRATION Registered at clinicaltrials.gov NCT03048695 09/02/2017.

Abstract
Nicotine is the psychoactive component given tobacco has several main components and acts as an agonist for nicotinic acetylcholine receptors (nAChRs) in the nervous system. Although the ligand-gated cation channels known as nAChRs are found throughout the nervous system and body, this review focuses on neuronal nAChRs. Individuals with psychiatric diseases such as schizophrenia, comorbid substance use disorders, attention-deficit hyperactivity disorder, major depression, and bipolar disorder have increased rates of smoking. These psychiatric disorders are associated with various cognitive deficits, including working memory, deficits in attention, and response inhibition functions. The cognitive-enhancing effects of nicotine may be particularly relevant predictors of smoking initiation and continuation in this comorbid population. Individuals with schizophrenia make up a significant proportion of smokers. Literature suggests that patients smoke to alleviate cognitive deficiencies due to the stimulating effects of nicotine. This narrative review examines the role of nicotine on cognition in schizophrenia.

Abstract
Cognitive impairment affects real-world functioning in people with schizophrenia who often face difficulties in their activities of daily living. Subjectively-assessed cognitive impairment can be evaluated through data on the patient's daily difficulties, as reported by the patient. However, the specific neurocognitive functions responsible for these cognitive impairments have not been clarified. We examined cognitive functioning in patients with schizophrenia using the Schizophrenia Cognition Rating Scale Japanese version (SCoRS-J) and the Brief Assessment of Cognition in Schizophrenia Japanese version (BACS-J). This study aimed to investigate the relationship between subjectively-assessed cognitive impairment and objectively assessed neurocognition in patients with schizophrenia. The results showed that patients' global rating scores of the SCoRS-J were significantly correlated with the BACS-J attention scores (r = −0.376, p < 0.008), which indicates that the difficulties patients perceived in their daily lives are due to deficits in attentional functioning, as measured by neurocognitive testing. Thus, our findings indicate that improving attentional functioning may also alleviate difficulties in patients' daily lives.

Abstract
Objectives COVID-19 constitutes an unprecedented mental health challenge to the world. At this critical time, it is important to identify factors that may boost individuals’ well-being or render individuals more resistant to the negative impact of COVID-19-related stressors. The goals of this study were to examine whether individuals’ and their partners’ worry about COVID-19 were linked to individuals’ psychological, social, and cognitive adjustment and test individuals’ and their partners’ mindfulness as possible moderators. Methods Cross-sectional, dyadic data were collected from 211 Chinese couples with kindergarten-aged children living in Hong Kong, China, during its fourth major outbreak of COVID-19 (between December 2020 and January 2021). Using paper-and-pencil questionnaires, fathers and mothers independently reported their worry about COVID-19, mindfulness, depressive symptoms, social difficulties, and cognitive problems. Results Actor-Partner-Interdependence Models revealed that, controlling for individuals’ gender and education levels, individuals’ worry about COVID-19 and mindfulness were positively and negatively associated with their own depressive symptoms, social difficulties, and cognitive problems, respectively. The worry of individuals’ partners was also positively associated with individuals’ depressive symptoms and social difficulties. These associations, however, were only significant when the partners had low but not high levels of mindfulness. Conclusions Our study highlighted the importance of studying the potential benefits of mindfulness at not only the individual but also the dyadic level.

Abstract
AIM Methods to identify and harness individual cognitive strengths while addressing relative weaknesses have the potential to complement recovery services for first-episode psychosis but systematic implementation is needed. We developed a cognitive health toolkit, trained teams from OnTrackNY, a network of coordinated specialty care (CSC) programs and examined toolkit feasibility and clinical utility during the first year of roll-out. METHODS The toolkit includes a clinician manual, assessment and decision-making tools, and a menu of cognitive health service options. Assessment uses the WRAT5-Reading subtest and a new Self-Assessment of Cognitive Functioning which, together, determine participant- and clinician-perceived cognitive health need. Program-level data were analysed for rates of assessment, identification of cognitive health needs and cognitive health service provision. RESULTS Data from 18 OnTrackNY teams included 933 participants, including 310 new admissions. Across teams, 43.9% of newly admitted participants received a WRAT5-Reading and 41.3% received a self-assessment. Of all assessments completed in the study period, 50.7% were at or within 3-months of admission and 69.1% were within the first year of program participation. Cognitive health need was identified by self-report (57.6%) and clinician-report (69.9%) and led to provision of specific services, including psychoeducation, compensatory skills training and in some cases restorative cognitive training. CONCLUSIONS Preliminary feasibility data are encouraging but barriers to assessment need to be identified and addressed. Rates of identified cognitive health need warrant further study of the implementation process and outcomes so that cognitive health assessment and treatment practices may ultimately be disseminated to CSC programs more broadly.

Abstract
This study aimed to investigate what characterizes individuals with schizophrenia who experience more or less subjective executive dysfunction in everyday life compared to objective executive performance on neuropsychological tests. Sixty-six participants with broad schizophrenia spectrum disorders completed a comprehensive assessment of executive function. Discrepancies between performance on neuropsychological tests (objective) and an extensive self-report questionnaire (subjective) of central executive functions (inhibition, shifting and working memory) were calculated. Higher level of self-efficacy was the best predictor of experiencing fewer subjective cognitive complaints compared to objective performance, followed by higher levels of disorganized symptoms. Depressive symptoms did not predict discrepancy between subjective and objective executive function. Higher estimated IQ predicted greater subjective working memory difficulties in everyday life despite better objective performance. Results may aid clinicians in the assessment and remediation of cognitive impairment. Low self-efficacy may identify individuals who are not able to utilize their potential executive functions in daily life. Interventions aimed at fostering self-efficacy ought to be included in cognitive remediation for these individuals. Disorganized symptoms could prove useful in identifying individuals who are in need of cognitive remediation for executive dysfunction, despite that they overestimate their skills. These individuals may benefit from efforts to increase insight into cognitive dysfunction.

Self-perceived cognitive impairments in psychosis ultra-high risk individuals: associations with objective cognitive deficits and functioning. NPJ SCHIZOPHRENIA 2020; 6:31. [PMID: 33188204 PMCID: PMC7666210 DOI: 10.1038/s41537-020-00124-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Accepted: 10/08/2020] [Indexed: 02/06/2023]
Abstract
There is a scarcity of evidence on subjectively reported cognitive difficulties in individuals at ultra-high risk (UHR) for psychosis and whether these self-perceived cognitive difficulties may relate to objective cognitive deficits, psychopathology, functioning, and adherence to cognitive remediation (CR). Secondary, exploratory analyses to a randomized, clinical trial were conducted with 52 UHR individuals receiving a CR intervention. Participants completed the Measure of Insight into Cognition—Self Report (MIC-SR), a measure of daily life cognitive difficulties within the domains of attention, memory, and executive functions along with measures of neuropsychological test performance, psychopathology, functioning, and quality of life. Our study found participants with and without objectively defined cognitive deficits reported self-perceived cognitive deficits of the same magnitude. No significant relationship was revealed between self-perceived and objectively measured neurocognitive deficits. Self-perceived cognitive deficits associated with attenuated psychotic symptoms, overall functioning, and quality of life, but not with adherence to, or neurocognitive benefits from, a CR intervention. Our findings indicate that UHR individuals may overestimate their cognitive difficulties, and higher levels of self-perceived cognitive deficits may relate to poor functioning. If replicated, this warrants a need for both subjective and objective cognitive assessment in at-risk populations as this may guide psychoeducational approaches and pro-functional interventions. Self-perceived cognitive impairments do not seem to directly influence CR adherence and outcome in UHR states. Further studies are needed on potential mediator between self-perceived cognitive deficits and functioning and quality of life.

How does awareness of cognitive impairment impact motivation and treatment outcomes during cognitive remediation for schizophrenia? Schizophr Res 2020; 218:70-75. [PMID: 32156497 PMCID: PMC7299790 DOI: 10.1016/j.schres.2020.02.014] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Revised: 02/27/2020] [Accepted: 02/29/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND There is concern that awareness of cognitive deficit among people with schizophrenia receiving Cognitive Remediation (CR) might undermine motivation, engagement, and CR outcomes. We therefore examined the relationship of subjective awareness of cognitive deficit to aspects of motivation and cognitive learning during an efficacious CR program. METHODS Individuals with schizophrenia/schizoaffective disorder who completed 30 sessions of CR (N = 67) were evaluated on cognitive performance, self-reported cognitive difficulties, intrinsic motivation and perceived competency for cognitive training tasks at the beginning and end of treatment. RESULTS We found no relationship between actual and perceived cognitive functioning when measured cross-sectionally or as difference scores, pre/post treatment. Greater awareness of cognitive problems was associated with lower perceived competency for cognitive tasks at treatment beginning and end-point (p-values < .05). The significant relationship between awareness of cognitive problems and perceived value of the treatment at end-point was fully mediated by perceived competency. While greater perceived competency was associated with shorter time to treatment completion (p = .0025), it was intrinsic motivation measured at end-point that was associated with cognitive change (p = .02). DISCUSSION While awareness of cognitive problems may not be a prerequisite for cognitive improvement during CR, it could impact engagement in, and how one values treatment via its effect on perceived competency. Results also highlighted the importance of intrinsic motivation for doing cognitive learning activities, given its relationship to cognitive gain. Further study is needed to understand how best to assess and address awareness of cognitive abilities within the CR setting.

Abstract
OBJECTIVE Misestimation of cognitive functioning has been largely described in individuals with schizophrenia. There is large evidence that correlations between subjectively assessed cognitive functioning and objectively determined cognitive functioning are weak in non clinical individuals and may be more closely related to other psychoaffective or clinical factors than to objective neuropsychological functioning. Surprisingly, no study to date has compared the associations between cognitive complaint and objective measures of cognitive functioning in individuals with schizophrenia and healthy controls. The main objective of this study was to 1) compare cognitive complaint between individuals with schizophrenia and non clinical controls, 2) explore the relationships between cognitive complaint and psychoaffective and clinical factors in the clinical group and 3) compare the relationships between subjective awareness of cognitive functioning and objective neuropsychological assessment in individuals with schizophrenia and non-clinical participants. METHOD In this study 30 individuals with schizophrenia and 20 non-clinical matched controls were included. In addition to objective cognitive measures and subjective cognition assessed by the Subjective Scale To Investigate Cognition In Schizophrenia, measures of psychotic symptoms, depression, and anxiety were included. RESULTS Schizophrenia patients reported higher cognitive complaints in comparison with controls. In individuals with schizophrenia, cognitive complaint subscores were differently associated with depression, anxiety, and negative symptoms. When depression was controlled for, the same number of correlations between self-rated measures of cognition and objective measures of cognition were found in both groups, but accuracy of self-assessment of cognition was lower in the schizophrenia group.When the schizophrenia group was divided into a high cognitive complaint group (SZ High CC) and a low cognitive complaint group (SZ Low CC), findings indicated that self-assessment of cognition in the SZ high CC was highly accurate (correlations with large effect sizes). By contrast the SZ low CC group severely misjudge their cognition. CONCLUSION A significant proportion of patients with schizophrenia can accurately estimate their cognitive skills. Self-awareness of cognitive deficits in individuals with schizophrenia is an heterogenous phenomenon and misestimation of cognitive functioning might have been overestimated, partly due to secondary psychoaffective factors. Caution is warranted before jumping to the conclusion that all individuals with schizophrenia misjudge their cognitive functioning.

Discrepancies between Self- and Clinical Staff Members' Perception of Cognitive Functioning among Patients with Schizophrenia Undergoing Long-Term Hospitalization. Occup Ther Int 2019; 2019:6547096. [PMID: 31777475 PMCID: PMC6875358 DOI: 10.1155/2019/6547096] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2019] [Revised: 08/13/2019] [Accepted: 08/29/2019] [Indexed: 11/17/2022] Open
Abstract
In Japan, long-term hospitalization of patients with schizophrenia is still prevalent, even though the focus of psychiatric care is shifting from hospitals to the community. Difficulties in discharge planning often arise because clinical staff members' functional assessment differs from that of patients' self-assessment. Therefore, we attempted to identify characteristics related to these perceptual differences to promote the development of more effective approaches toward the discharge and societal reintegration of patients with schizophrenia undergoing prolonged hospitalization. Forty-eight long-term inpatients (23 men and 25 women with a mean age of 60.72 years) with schizophrenia were examined using the Schizophrenia Cognition Rating Scale Japanese version (SCoRS-J), Life Skills Profile (LSP), and Profile of Mood States- (POMS-) Brief Form. Differences between patients' self-ratings and clinical staff members' ratings on the SCoRS-J were used to divide patients into overestimators, underestimators, and accurate raters. These groups were then comparatively analyzed. Accordingly, overestimators displayed significantly severe cognitive dysfunction on the SCoRS-J objective ratings (p = .001) and significantly less difficulty on the SCoRS-J subjective ratings (p = .002) as compared to underestimators. Overestimators also scored significantly lower on the communication (p = .012) and responsibility (p = .021) LSP subscales compared to underestimators, and the total LSP score for overestimators was significantly lower compared to accurate raters (p = .036) and underestimators (p = .009). However, underestimators displayed significantly higher confusion on the titular POMS subscale than did overestimators (p = .021). These findings indicate that, among the three groups, overestimators scored lowest for objectively rated functioning. In contrast, underestimators attained the highest functioning; however, they were also confused. Clinical staff should examine how patients' self-perceptions deviate from the perceptions of staff and implement an appropriate approach considering the patient characteristics revealed from the results of this study.

Divergence of subjective and performance-based cognitive gains following cognitive training in schizophrenia. Schizophr Res 2019; 210:215-220.

Abstract
BACKGROUND Cognitive training is effective for improving cognitive performance among people with schizophrenia. An individual's perception of their own cognition is dissociable from performance on objective cognitive tests. Since subjective cognitive benefit may impact engagement, motivation, and satisfaction with time-intensive cognitive interventions, this study aimed to determine whether subjective cognitive difficulties improve in conjunction with cognitive gains following 30 h of cognitive training. METHODS Patients with schizophrenia or schizoaffective disorder (N = 46) were randomized to treatment as usual (TAU) or TAU augmented with auditory-targeted cognitive training (TCT). All participants completed assessment batteries at baseline and follow-up. As previously reported, the TCT group showed significant improvements in verbal learning and memory and reductions in auditory hallucinations relative to the TAU group. RESULTS Subjective cognitive difficulties did not significantly improve following TCT, even among TCT participants who showed improvements in cognitive performance (all ps > 0.05). Subjective cognitive difficulties were significantly associated with severity of depressive symptoms and hallucinations (r = 0.48 and r = 0.28, p < 0.001), but not global or specific domains of cognition (all rs < 0.1) at baseline. There were no significant relationships between change in subjective cognitive difficulties and change in cognitive or clinical variables (all ps > 0.05). DISCUSSION Patients with schizophrenia do not detect change in their cognition following cognitive training, even among those who showed robust gains in cognitive performance. Failure to detect improvement may undermine treatment engagement, motivation, and satisfaction. Translating score improvements on the cognitive exercises into tangible metrics, and providing ongoing, clinician-delivered feedback on performance may facilitate patient ability to detect improvements and improve motivation to engage with cognitive training interventions.

Abstract
Background Motivation and engagement are important factors associated with therapeutic outcomes in cognitive training for schizophrenia. The goals of the present report were to examine relations between objective treatment engagement (number of sessions attended, amount of homework completed) and self-reported motivation (intrinsic motivation and perceived competence to complete cognitive training) with neurocognitive and functional outcomes from cognitive training. Methods Data from a clinical trial comparing two cognitive training approaches in schizophrenia-spectrum disorders were utilized in the current report (n = 38). Relations were examined between baseline intrinsic motivation, perceived competence, homework completion, and session attendance with improvements in neurocognition, functional competence, and community functioning. Results Number of sessions attended (r = 0.38) and time doing homework (r = 0.51) were significantly associated with improvements in neurocognition. Homework completion was associated with change in community functioning at a trend-level (r = 0.30). Older age was associated with greater treatment engagement (β = 0.37) and male biological sex was associated with greater self-reported motivation (β = 0.43). Homework completion significantly mediated the relationship between session attendance and neurocognitive treatment outcomes. Conclusions Objective measures of treatment engagement were better predictors of treatment outcomes than subjective measures of motivation. Homework completion was most strongly related to treatment outcomes and mediated the relationship between session attendance and treatment outcomes, suggesting continued engagement with cognitive stimulation may be an especially important component of cognitive remediation programs. Future research should examine methods to improve homework completion and session attendance to maximize therapeutic outcomes.

Abstract
Background: People with schizophrenia may have a negative self-perception of mental illness. However, the relationship between the self-perception of illness and subjective and objective cognitive functioning remains unclear. Method: Thirty-seven people with schizophrenia were enrolled in the study group. All subjects completed self-reported self-perception of mental illness questionnaires (Birchwood Insight Scale [BIS], Internalized Stigma of Mental Illness [ISMI]), subjective cognitive functioning (Scale to Investigate Cognition in Schizophrenia [SSTICS]) and objective cognitive functioning (Luria Nebraska Neuropsychological Battery [LNNB]). Results: Spearman's rank analysis showed that awareness of illness (domain of insight) was positively associated with most domains of SSTICS and ISMI. Total insight was positively correlated with alienation (domain of ISMI). Need for treatment (domain of insight) was negatively correlated with stigma resistance (domain of ISMI). Awareness of symptoms (domain of insight) and total insight were negatively associated with receptive speech and arithmetic (LNNB subtest), respectively. ISMI was positively correlated with most domains of SSTICS, but not with LNNB. The group with good insight had higher scores in attention (domain of SSTICS) and total SSTICS and alienation, stereotype endorsement, social withdrawal (domains of ISMI) and total ISMI than the group with poor insight. The group with mild to moderate internalized stigma had higher scores in explicit memory, attention, language, praxia (domains of SSTICS) and total SSTICS than the group with no internalized stigma. Conclusion: We identified that awareness of illness (domain of insight), internalized stigma were significantly associated with most domains of SSTICS, but not with LNNB. Total insight and awareness of symptoms (domain of insight) were significantly associated with receptive speech and arithmetic (LNNB subtest), respectively. Schizophrenia with higher insight or more internalized stigma reported more subjective cognitive impairment. Future studies with larger samples involving follow up are necessary to verify our findings and extend the applicability.

Abstract
INTRODUCTION The Computerized Interactive Remediation of Cognition - Training for Schizophrenia (CIRCuiTS) is a form of cognitive remediation therapy developed to target neurocognitive and metacognitive deficits of people with schizophrenia, which have a detrimental impact on real-life functioning. The English version of CIRCuiTS demonstrated good acceptability and feasibility. A recent randomized controlled trial provided evidence that the program improves memory and functioning, and that the impact on functional outcome is mediated by metacognition. The next steps in the development of CIRCuiTS include both: 1) the translation and adaptation of the program in different cultural settings; and 2) the demonstration of feasibility, acceptability and effectiveness of a standardized method to administer CIRCuiTS remotely. PURPOSE To implement the CIRCuiTS Italian version and to assess acceptability, feasibility and efficacy of a standardized method to administer CIRCuiTS remotely. METHODS Participants were assessed at baseline and received up to 40 CIRCuiTS therapy sessions, three times a week, for about 1 hr over a three-month period. Participants were reassessed post-treatment. RESULTS The program demonstrated good feasibility and high acceptability when assessed by the number of dropouts and evaluation of patients' satisfaction. Participants improved in learning, speed of processing, working memory and executive control. They showed a reduction in disorganization and improvement in self-esteem, functional capacity, and real-life functioning. CONCLUSION In this study, a standardized protocol for using CIRCuiTS from home was implemented. The first set of data showed in the paper is encouraging. The proposed procedure could lead to a dropout reduction while maintaining the efficacy of the program.

Abstract
Social cognition refers to the mental operations underlying social interactions. Given the major role of social cognitive deficits in the disability associated with severe psychiatric disorders, they therefore constitute a crucial therapeutic target. However, no easily understandable and transnosographic self-assessment scale evaluating the perceived difficulties is available. This study aimed to analyze the psychometric qualities of a new self-administered questionnaire (ACSo) assessing subjective complaints in different domains of social cognition from 89 patients with schizophrenia, schizoaffective disorders, bipolar disorders or autism. The results revealed satisfactory internal validity and test-retest properties allowing the computation of a total score along with four sub scores (attributional biases, social perception and knowledge, emotional perception and theory of mind). Moreover, the ACSo total score was correlated with other subjective assessments traditionally used in cognitive remediation practice but not with objective neuropsychological assessments of social cognition. In summary, the ACSo is of interest to complete the objective evaluation of social cognition processes with a subjective assessment adapted to people with serious mental illness or autism spectrum disorder.

Abstract
INTRODUCTION Individuals with schizophrenia present across a spectrum of symptomatology. Disability remains a debilitating reality across varying disease presentations and remains pervasive despite psychiatric medications. Cognition (neuro/social cognition) and negative symptoms have emerged as the strongest predictors of real-world disability, but account for <50% of the variance in outcomes. METHODS Our attempts to determine what accounts for the remaining 50% of variance has shown that poor introspective accuracy (IA) may be the most potent predictor of functional outcomes 25% of individuals with schizophrenia. We define IA as the adequacy of self-assessments of ability, skills, performance, or decisions. We suggest that IA is a progression of metacognition and can extend beyond cognition to include misestimation of prior and likely future performance in social or other adaptively relevant situations. RESULTS Additionally, IA is bidirectional and self-orientated. Emerging research has found that IA of neurocognitive ability better predicts everyday functional deficits than scores on performance-based measures or neurocognitive skills and has found that IA of social cognition accounts unique variance in real-world disability above social cognitive performance. DISCUSSION We argue that impaired IA, affecting 25-50% of patients with schizophrenia, in the absence or minimal presence of other impairments might be the most powerful predictor of functional outcomes.

Abstract
Introspective accuracy (IA) refers to the ability to accurately assess one's own skills and capabilities. Recent work provides evidence of IA deficits in schizophrenia that are predictive of everyday functioning. Thus, IA deficits are an important target to understand mechanistically. The current study used fMRI to assess neural activation in 32 healthy controls and 31 individuals with schizophrenia as they completed IA and control versions of a social cognitive task (i.e., emotion recognition). Analyses revealed different areas of IA-specific neural activity between groups including activations of rostrolateral prefrontal cortex (rlPFC) and dorsal anterior cingulate cortex in healthy individuals that were absent in patients. Direct group comparisons revealed greater IA-specific activation for healthy individuals in right rlPFC, a region thought to be critical for successful IA. For healthy individuals only, activation in rlPFC was positively correlated with IA ability, but no association was observed for patients. Further, among individuals with schizophrenia, increased activation of rlPFC during judgments of IA was positively correlated with better informant-reported interpersonal functioning. These results suggest that reduced specialization of IA-related neural activation may contribute to impaired IA in schizophrenia and also highlight IA as a potential target for remediation programs aimed at improving real-world functioning.

Abstract
OBJECTIVES To critically appraise the measurement property evidence (ie, psychometric) for 8 observation-based financial management assessment instruments. DATA SOURCES Seven databases were searched in May 2015. STUDY SELECTION Two reviewers used an independent decision-agreement process to select studies of measurement property evidence relevant to populations with adulthood acquired cognitive impairment, appraise the quality of the evidence, and extract data. Twenty-one articles were selected. DATA EXTRACTION This review used the COnsensus-based Standards for the selection of health Measurement Instruments review guidelines and 4-point tool to appraise evidence. After appraising the methodologic quality, the adequacy of results and volume of evidence per instrument were synthesized. Measurement property evidence with high risk of bias was excluded from the synthesis. DATA SYNTHESIS The volume of measurement property evidence per instrument is low; most instruments had 1 to 3 included studies. Many included studies had poor methodologic quality per measurement property evidence area examined. Six of the 8 instruments reviewed had supporting construct validity/hypothesis-testing evidence of fair methodologic quality. There is a dearth of acceptable quality content validity, reliability, and responsiveness evidence for all 8 instruments. CONCLUSIONS Rehabilitation practitioners assess financial management functions in adults with acquired cognitive impairments. However, there is limited published evidence to support using any of the reviewed instruments. Practitioners should exercise caution when interpreting the results of these instruments. This review highlights the importance of appraising the quality of measurement property evidence before examining the adequacy of the results and synthesizing the evidence.

Abstract
AIM The aim of this study was to provide a short version of the Davos Assessment of Cognitive Biases Scale (DACOBS), which is a self-report tool to assess cognitive distortions related to psychosis. METHODS A principal component analysis (PCA) was conducted on a large non-clinical sample (n=1207) and cross-validated with a confirmatory factor analysis on an independent non-clinical sample (n=653). Discriminative validity was performed by contrasting the high risk for psychosis non-clinical sample (n=63), low risk for psychosis non-clinical sample (n=152), patients with schizophrenia (n=105), and patients with depression (n=56). Correlations between symptoms, cognitive functions, source monitoring deficits, and jumping to conclusions were performed among a subgroup of patients with schizophrenia. RESULTS An 18-item scale (DACOBS-18) with a four-factor solution was established. Internal consistency (α=0.84) and test-retest reliability (r=0.84, p<0.001) were good. The DACOBS-18 has satisfactory discriminative power, with 99.1% sensitivity and 74.3% specificity in discriminating low risk for psychosis from schizophrenia patients. The DACOBS-18 subscales correlate significantly with psychotic symptoms and psychotic-like experiences. After Bonferroni correction, significant correlations between Safety Behaviors and neuropsychological functioning were found. CONCLUSIONS The DACOBS-18 is a reliable scale with satisfactory discriminative power and thus may be a valuable self-report screening tool for use in everyday clinical practice with psychotic patients and with people at risk for psychosis. Further research on its relationship to objective cognitive measures is needed.

Abstract
BACKGROUND Cigarette smoking is the main cause of preventable death in developed countries. While the direct positive behavioral reinforcing effect of nicotine has historically been considered the primary mechanism driving the development of TUD, accumulating contemporary research suggests that the cognitive-enhancing effects of nicotine may also significantly contribute to the initiation and maintenance of TUD, especially in individuals with pre-existing cognitive deficits. METHODS We provide a selective overview of recent advances in understanding nicotine's effects on cognitive function, a discussion of the role of cognitive function in vulnerability to TUD, followed by an overview of the neurobiological mechanisms underlying the cognitive effects of nicotine. RESULTS Preclinical models and human studies have demonstrated that nicotine has cognitiveenhancing effects. Attention, working memory, fine motor skills and episodic memory functions are particularly sensitive to nicotine's effects. Recent studies have demonstrated that the α4, β2, and α7 subunits of the nicotinic acetylcholine receptor (nAChR) participate in the cognitive-enhancing effects of nicotine. Imaging studies have been instrumental in identifying brain regions where nicotine is active, and research on the dynamics of large-scale networks after activation by, or withdrawal from, nicotine hold promise for improved understanding of the complex actions of nicotine on human cognition. CONCLUSION Because poor cognitive performance at baseline predicts relapse among smokers who are attempting to quit smoking, studies examining the potential efficacy of cognitive-enhancement as strategy for the treatment of TUD may lead to the development of more efficacious interventions.

Abstract
Negative symptoms often inhibit the social integration of people suffering from schizophrenia. Reducing severe negative symptoms (SNS) in a clinically relevant way is a major unmet need. The aim of this study was to investigate whether Integrated Neurocognitive Therapy (INT), a group cognitive remediation therapy (CRT), reduces SNS in schizophrenia outpatients. INT was compared with Treatment As Usual (TAU) in a randomized-controlled trial (RCT). A total of 61 SNS outpatients participated in the study, 28 were allocated to the INT group and 33 to the TAU group. A test-battery was used at baseline, post-treatment at 15weeks, and 1-year-follow-up. Remission rates of SNS after therapy were significantly higher for INT compared to TAU. A trend favoring INT was obtained at follow-up. Furthermore, INT showed significantly higher functional outcome during follow-up compared to TAU. Regarding cognition, the strongest significant effect was found in attention post-treatment. No effects between groups on more complex neurocognition and social cognition were evident. SNS outpatients seem to accept INT group intervention as suggested by the high attendance rate.

Abstract
Cognitive remediation (CR) is an intensive intervention targeting cognitive impairment with the aim of improving functioning in people with psychotic disorders. Shorter forms of CR based on metacognition and targeting awareness of cognitive problems may be more appropriate for acute inpatient settings where time is limited. The objective of the study was to evaluate the feasibility and acceptability of a new brief course of CR targeting cognitive and metacognitive difficulties within an acute inpatient psychiatric setting. Thirteen male service users with psychosis received a three-week course of CR. Participants were assessed at baseline and post-treatment on cognitive measures, subjective cognitive complaints, functional impairment, and symptom severity. Feasibility was assessed based on engagement, attendance, and attrition. Acceptability was evaluated through treatment satisfaction. Eight participants completed therapy, with 81% session attendance. Therapy was considered acceptable, with the majority of participants considering it satisfactory. Potential benefit analysis showed a significant post-treatment improvement in global cognition and memory. Subjective cognitive complaints did not change over time. It was concluded that it is feasible to deliver brief CR in an acute inpatient setting. Context of delivery and engagement are challenges for optimal therapy implementation. CR protocol adaptations made to promote metacognitive competencies may compensate for lack of intensive practice.

Abstract
Justification: Recent studies showed that neurocognitive insight difficulties occur in subjects with schizophrenia. However, little is known about the different profiles of neurocognitive insight, their relations with neurocognitive functioning, and their specific links with mood factors and outcomes. Aim: The study explored profiles of relationships between objective and subjective cognition in persons with schizophrenia spectrum disorders (SSD) and associations with quality of life (QoL), stigmatization, and mood factors. Method: Participants were 69 outpatients with an SSD. Cluster analysis (Ward method) was performed to explore profiles of interactions between subjective complaints and objective cognitive performances. Analyses of variance (ANOVAs) were then conducted to compare groups on anxiety and depression levels, stigmatization, and QoL. Results: Cluster analysis produced 3 groups: high cognitive impairment/moderate cognitive complaints (N = 26), good cognitive functioning/moderate cognitive complaints (N = 22), and moderate cognitive impairment/high cognitive complaints (N = 21). The second group has higher objective QoL, and the third group has higher levels of anxiety, depression, and stigmatization. Our results show that (a) not all patients with SSD have neurocognitive insight difficulties, (b) relation between objective and subjective cognition is not linear, and (c) differences between profiles may have theoretical and clinical implications.

Abstract
Neurocognitive impairment is a core component of schizophrenia affecting everyday functioning; the extent to which individuals with schizophrenia show awareness of neurocognitive impairment (neurocognitive insight) is unclear. This study investigated neurocognitive insight and examined the cross-sectional relationships between neurocognitive insight and objective neurocognition and functional capacity performance in a large outpatient sample. 214 participants with schizophrenia-spectrum disorders completed measures of neurocognition, functional capacity, and self-reported neurocognitive problems. Latent profile analysis classified participants with regard to neuropsychological performance and self-report of neurocognitive problems. The resulting classes were then compared on executive functioning performance, functional capacity performance, and psychiatric symptom severity. More than three quarters of the sample demonstrated objective neurocognitive impairment (global deficit score≥0.50). Among the participants with neurocognitive impairment, 54% were classified as having "impaired" neurocognitive insight (i.e., reporting few neurocognitive problems despite having objective neurocognitive impairment). Participants with impaired vs. intact neurocognitive insight did not differ on executive functioning measures or measures of functional capacity or negative symptom severity, but those with intact neurocognitive insight reported higher levels of positive and depressive symptoms. A substantial portion of individuals with schizophrenia and objectively measured neurocognitive dysfunction appear unaware of their deficits. Patient self-report of neurocognitive problems, therefore, is not likely to reliably assess neurocognition. Difficulty self-identifying neurocognitive impairment appears to be unrelated to executive functioning, negative symptoms, and functional capacity. For those with intact neurocognitive insight, improving depressive and psychotic symptoms may be a valuable target to reduce illness burden.

Abstract
OBJECTIVES Cognitive remediation (CR) is a therapy targeting cognitive difficulties in psychiatric disorders. We recently develop a novel CR program for people with psychosis with a focus on metacognitive skills individually supported by a therapist. This study aims to assess the acceptability and feasibility of implementing CR in small groups where therapist support is shared amongst service users. DESIGN Control group design with non-randomized group allocation. METHOD Twenty-five service users with a diagnosis of schizophrenia participated. Ten received group CR and 15 individual CR (i.e., one therapist for each service user). Both therapy formats were supported by one therapist. Participants were assessed before and after therapy with neuropsychological tests assessing different cognitive domains, self-assessed cognitive complaints, and psychotic symptoms. Treatment satisfaction questionnaires and therapist's session ratings were also collected for group CR. RESULTS Dropout rate was 20% for both methods. Session attendance was 74% for group CR and 86% for individual CR. Service users evaluated positively group CR and considered it helpful; therapists rated this delivery format feasible. Exploratory analysis suggested that the two methods have similar effects on cognition. After therapy, service users showed improvements in recall memory, reduced negative symptoms, and reported fewer cognitive complains. CONCLUSIONS It is feasible and acceptable for people with schizophrenia to take part in small CR therapy groups. The reduced therapist contact compared to individual therapy was well tolerated and may help sustain independent work. The small group format allows therapists to spend sufficient time to support the use of metacognitive strategies. PRACTITIONER POINTS CR small groups are feasible and acceptable for service users and therapists. Therapist support can be shared. Metacognitive-based CR can improve cognition and may benefit awareness and negative symptoms.

Abstract
Cognitive awareness in patients with schizophrenia is crucial for clinical management of cognitive deficits. Traditional approaches using self-report inventories have questionable validity and reliability. Using the Feeling-of-Knowing (FOK) procedure to measure metamemory might overcome such weakness. A cross-sectional study comparing 40 patients and 40 demographically matched normal controls, using a recall-judgment-recognition (RJR) procedure and the Hamann coefficient was conducted to examine whether patients with schizophrenia have FOK deficits and what neurocognitive mechanism might account for these deficits. General IQ, executive function, and memory tests were also assessed. The results show that as a group, patients with schizophrenia had impaired FOK ability and evidenced a disposition to underestimate their memory performance. However, patient's FOK ability was variable, with 42.5% of patients exhibited a below chance level performance. There were marked relationships between FOK and set formation and visual recognition abilities in healthy controls, while such feature was not evident in patient group. These findings are in line with the prefrontal cortex dysfunction, reduced intrapsychic monitoring ability, and impaired utilization of mental resources noticed in patients with schizophrenia. A routine evaluation of metamemory function by FOK might be helpful for designing customized cognitive rehabilitation programs considering their missed estimation of memory capacity.

Abstract
Deficits in social functioning are a core symptom of schizophrenia and an important criterion for evaluating the success of treatment. However, there is little agreement regarding its measurement. A common, often cited instrument for assessing self-reported social functioning is the Social Functioning Scale (SFS). The study aimed to investigate the reliability and validity of the German translation. 101 patients suffering from schizophrenia (SZ) and 101 matched controls (C) (60 male / 41 female, 35.8 years in both groups) completed the German version. In addition, demographic, clinical, and functional data were collected. Internal consistency was investigated calculating Cronbach's alpha for SFS full scale (α: .81) and all subscales (α: .59-.88). Significant bivariate correlation coefficients were found between all subscales as well as between all subscales and full scale (p <.01). For the total sample, principal component analysis gave evidence to prefer a single-factor solution (eigenvalue ≥ 1) accounting for 48.5 % of the variance. For the subsamples, a two-component solution (SZ; 57.0 %) and a three-component solution (C; 65.6 %) fitted best, respectively. For SZ and C, significant associations were found between SFS and external criteria. The main factor "group" emerged as being significant. C showed higher values on both subscales and full scale. The sensitivity of the SFS was examined using discriminant analysis. 86.5% of the participants could be categorized correctly to their actual group. The German translation of the SFS turned out to be a reliable and valid questionnaire comparable to the original English version. This is in line with Spanish and Norwegian translations of the SFS. Concluding, the German version of the SFS is well suited to become a useful and practicable instrument for the assessment of social functioning in both clinical practice and research. It accomplishes commonly used external assessment scales.

Abstract
INTRODUCTION This study explored whether integrity of executive functioning is required for good neurocognitive insight (NI) in subjects with schizophrenia. METHODS NI was measured by subtracting executive difficulties (errors in the Modified Card Sorting Task) from executive cognitive complaints (Subjective Scale to Investigate Cognition in Schizophrenia) in 40 outpatients with schizophrenia and 42 normal controls. The schizophrenia sample was a priori divided into two subgroups on the basis of executive level. Multivariate analyses were conducted to compare groups and to control for potential confounding factors. RESULTS Only the schizophrenia dysexecutive subgroup had a poorer NI compared to normal controls. Group differences remained significant after adjustment for potential confounding factors (education, depression, anxiety and self-esteem). CONCLUSION These results provide support for the hypothesis that executive dysfunctioning is a limiting factor for NI, independently from depressive and anxiety symptoms.

Abstract
The use of restraints is a controversial issue even though legal regulations may seem straightforward. Our aims were to evaluate the forensic patients' opinions on certain aspects of restraining and to compare these opinions with the current legal norms. Inpatients with schizophrenia or schizoaffective disorder at the Department of Forensic Psychiatry in Popovača, Croatia, were asked the following questions about the use of mechanical restraints: (a) Should the patients' family be informed about the use of restraints? (b) Should the physician ask the patient whether to inform the family about the use of restraints? (c) Can the use of restraints be a kind of punishment for intentionally aggressive behavior toward people in their environment? and (d) Should restraints be used if the patient requests to be restrained? The patients were assessed according to the Temperament and character inventory and Positive and Negative Symptom Scale. Fifty-four forensic patients with a history of serious offences were included in the study. Their average age was 44.7 (± 8.39) years and the mean duration of their treatment was 6.6 (± 5.08) years. There was no predominant opinion on sharing the information with the family, but there was a relationship between the opinions and psychopathology and personality. Regardless of the patients' mental state and personality, the opinions on the voluntary use of restraints and the use of restraints as punishment for intentionally aggressive behavior were mainly positive. The patients' opinions suggest a need for the implementation of more specific guidelines in the area of forensic psychiatry.

Abstract
INTRODUCTION Cognitive impairment is a pervasive feature of schizophrenia, and is a major determinant of the functional disability that is characteristic of the disorder. However, research investigating whether patients with schizophrenia show a deficit awareness remains unclear. The present study aimed to replicate and extend previous research comparing subjective and objective measures of cognition. METHODS . Thirty patients with a diagnosis of schizophrenia or schizoaffective disorder were administered the subjectively assessed Schizophrenia Cognitive Rating Scale (SCoRS) and the objective Brief Assessment of Cognition in Schizophrenia (BACS), which each assess overall global functioning and four specific neurocognitive domains (i.e., Verbal Memory, Working Memory, Processing Speed, and Reasoning and Problem Solving). Because deficit awareness may influence the likelihood of patients engaging in treatments designed to improve cognitive functioning, patients' attitudes towards such therapies were also contrasted with these subjective and objective measures of cognitive functioning. RESULTS Patients' subjective appraisals did not significantly correlate with the objective neuropsychological assessments for global functioning or any specific neurocognitive domains. However, patients accurately deduced that their memory domains were more impaired than the other domains, and there was a trend for patients to exaggerate their Reasoning and Problem Solving deficits. This suggests that patients show some level of deficit awareness, when overestimating "deficits" for domains that are not impaired. Finally subjective, but not objective, measures of cognitive functioning correlated significantly with willingness to participate in cognitive-enhancing therapies. CONCLUSIONS These results suggest that although patients' perceptions of their cognitive function are no substitute for objective neuropsychological test data, patients do possess a level of deficit awareness which may, in turn, influence willingness to participate in interventions such as cognitive rehabilitation.

Abstract
BACKGROUND Cognitive remediation (CR) has shown significant promise in addressing the cognitive deficits that accompany serious mental illness. However, this intervention does not appear to completely ameliorate the cognitive deficits that accompany these illnesses. D-cycloserine (DCS), an NMDA receptor partial agonist, has been shown to enhance the therapeutic benefits of learning-based psychosocial interventions for psychiatric disorders. Thus, the goal of this study is to examine the utility of combining cognitive remediation and d-cycloserine in the treatment of cognitive deficits among individuals with bipolar disorder. METHODS/DESIGN Approximately forty individuals with bipolar disorder will be recruited to participate in this study. Participants will be randomized to one of two study arms: CR + DCS or CR + placebo. The primary outcome for this study is change in cognitive functioning. We will also examine several secondary outcomes, including the rate of change of cognitive functioning, social functioning, and symptomatology. DISCUSSION Cognitive deficits are a rate-limiting factor in functional recovery among individuals with bipolar disorder. Unfortunately, treatment options for these deficits are limited. The results of the proposed study may reveal a valuable intervention strategy (i.e., CR with concurrent DCS) to improve cognitive functioning among individuals with bipolar disorder. Ultimately, this treatment strategy may prove useful in addressing the cognitive deficits that are ubiquitous across serious mental illnesses. TRIAL REGISTRATION ClinicalTrials.gov NCT01934972.

Abstract
BACKGROUND People with a diagnosis of schizophrenia have limited metacognitive awareness of their symptoms. This is also evident for cognitive difficulties when neuropsychological assessments and self-reports are compared. Unlike for delusions and hallucinations, little attention has been given to factors that may influence the mismatch between objective and subjectively reported cognitive problems. Symptom severity, and also self-esteem and social functioning, can have an impact on cognitive problem perception and help to explain the gap between objective and subjective cognitive assessments in psychosis. METHOD One-hundred participants with a diagnosis of schizophrenia were recruited and assessed with a comprehensive neuropsychological battery, a measure of awareness of cognitive problems and measures of psychotic symptoms, social and behavioural functioning and self-esteem. Regression was used to investigate the influence of symptoms, social functioning and self-esteem, and patients with different levels of cognitive problem awareness were contrasted. RESULTS Simple correlation analysis replicated the lack of association between objective cognitive measures and metacognitive awareness of cognitive problems. However, the results of the regression analyses highlight that self-esteem and negative symptoms predict metacognitive awareness. When significant predictors were controlled, individuals with better awareness had more impaired working memory but higher IQ. CONCLUSIONS Poor self-esteem and high negative symptoms are negatively associated with metacognitive awareness in people with schizophrenia. Interventions that aim to improve cognition should consider that cognitive problem reporting in people with schizophrenia correlates poorly with objective measures and is biased not only by symptoms but also by self-esteem. Future studies should explore the causal pathways using longitudinal designs.

Abstract
Subjective measurements of cognition have seldom been used in schizophrenia. This is mainly due to the assumption that such measurements lack sensitivity in a disorder characterized by poor insight. We investigated the capacity of BRIEF-A (Behavior Rating Inventory of Executive Function - Adult Version: a self-administered, ecological questionnaire) to identify executive deficits in adults with schizophrenia. The global score and each domain-specific score was significantly lower in patients than in healthy controls. BRIEF-A could be a useful complement to objective measurements, providing a subjective assessment of everyday consequences of executive dysfunction in patients with schizophrenia.

Abstract
INTRODUCTION The Schizophrenia Cognition Rating Scale (SCoRS), an interview-based assessment of cognition, has proved to be a valid measure of cognitive performance in patients with schizophrenia. OBJECTIVE The aims of this study were to analyze the validity of this scale in a naturalistic setting representative of the Italian system of psychiatric care, and to test whether the SCoRS could be appropriately used in different phases of illness and contexts of care. METHODS Eighty-six patients with schizophrenia (DSM-IV-TR criteria) (N = 59 clinically stabilized patients; N = 27 recently hospitalized patients) were administered the SCoRS. The reliability of SCoRS was assessed and global ratings were correlated with neurocognitive, clinical, and psychosocial functioning measures. RESULTS SCoRS inter-rater and test-retest reliability were high. In clinically stabilized patients, SCoRS global ratings were significantly correlated with composite scores of cognitive performance (global cognitive index: r = -0.570, P<0.001), symptoms (Positive and Negative Syndrome Scale (PANSS) total score: r = 0.602, P < 0.001), and psychosocial functioning (Global Assessment of Functioning (GAF): r = -0.532, P<0.001; Health of the Nation Outcome Scale (HoNOS): r = 0.433, P < 0.001). On the other hand, no such correlations were found in recently hospitalized patients. Correlations with neuropsychological and functional measures were less significant as the severity of the patients' symptoms, especially positive symptoms, increased. CONCLUSION The SCoRS is a valid measure of cognitive performance and is related to psychosocial functioning, especially in clinically stable patients with schizophrenia. The usefulness of the SCoRS in patients recently admitted to hospital for an acute phase of illness is uncertain.

Abstract
OBJECTIVE To obtain Food and Drug Administration approval for the treatment of cognitive impairments associated with schizophrenia, a drug will need to demonstrate benefits beyond those that may be documented on objective cognitive tests. Interview-based measures of cognition such as the Cognitive Assessment Interview (CAI) are candidate coprimary outcome measures. METHODS Psychiatrically stable schizophrenia outpatients (n=150) were studied using the CAI to obtain information about cognitive functioning from both the patient and an informant. Patients also received objective assessments of neurocognition, functional capacity, functional outcome, and symptoms, at baseline and 1 month later. RESULTS The CAI had good internal consistency (Cronbach's alpha=.92) and good test-retest reliability (r=.83). The CAI was moderately correlated with objective neurocognitive test scores (r's=-.39 to -.41) and moderately correlated with social functioning (r=-.38), work functioning (r=-.48), and overall functional outcome (r=-.49). The correlations of CAI scores with external validity indicators did not differ significantly by source of information (patient alone ratings were valid). Overall functional outcome correlated more strongly with patient CAI scores (r=-.50) than with objective neurocognitive test scores (r=.29) or functional capacity (r=.29). CONCLUSIONS Field testing of the CAI produced reliable ratings of cognitive functioning that were correlated with functional outcome. Patient ratings alone yielded scores with reliability and validity values appropriate for use in clinical trials. The CAI appears to provide useful complementary information and possesses practical advantages for rating cognitive functioning including an interview-based method of administration, brief assessment time (15 min for the patient assessment), little or no practice effects, and ease of scoring.

Abstract
OBJECTIVE Cognitive problems and biases play an important role in the development and continuation of psychosis. A self-report measure of these deficits and processes was developed (Davos Assessment of Cognitive Biases Scale: DACOBS) and is evaluated in this study. METHODS An item pool made by international experts was used to develop a self-report scale on a sample of 138 schizophrenia spectrum patients. Another sample of 71 patients was recruited to validate the subscales. A group of 186 normal control subjects was recruited to establish norms and examine discriminative validity. RESULTS Factor analyses resulted in seven factors, each with six items (jumping to conclusions, belief inflexibility bias, attention for threat bias, external attribution bias, social cognition problems, subjective cognitive problems and safety behavior). All factors independently explained the variance (eigenvalues>2) and total explained variance was 45%. Reliability was good (Cronbach's alpha=.90; split-half reliability=.92; test-retest reliability=.86). The DACOBS discriminates between schizophrenia spectrum patients and normal control subjects. Validity was affirmed for five of seven subscales. The scale 'Subjective Cognitive problems' was not associated with objective cognitive functioning and 'Social cognition problems' was not associated with the Hinting task, but with the scale measuring ideas of social reference. CONCLUSIONS The DACOBS scale, with seven independent subscales, is reliable and valid for use in clinical practice and research.

Abstract
People with schizophrenia have neuro-cognitive deficits that are associated with poor functional outcome, yet their awareness of their cognitive deficiencies is variable. As new treatments for cognition are developed, it will be important that patients are receptive to the need for more therapy. Since insight into symptoms has been associated with treatment compliance, it may be of value to provide psycho-education to improve understanding about cognition in schizophrenia. We report a randomized controlled trial that enrolled 80 subjects in either a brief psycho-education intervention about cognition, or a control condition. Subjects in the two conditions did not differ at baseline in insight or receptiveness to treatment, or on demographic, cognitive, or psychiatric variables. Current cognitive impairment of subjects was evidenced by the indice of working memory, attention and executive functioning abilities, (X=77.45 intervention group; 82.50 control condition), that was significantly below both the normative mean and estimated average premorbid IQs (X=101.3 intervention group; X=104.57 control condition). Multivariate repeated measures ANOVAs indicated that subjects who received the psycho-education did not improve insight into their cognitive deficits or willingness to engage in treatment for cognitive dysfunction. While the failure to find a significant impact of this intervention on awareness of cognitive deficit and receptiveness to cognitive treatment raises questions about the malleability of insight into neuro-cognitive deficits, the intervention was briefer than most reported psycho-education programs and multi-session formats may prove to be more effective.

Abstract
Lack of insight into illness is a prevalent and distinguishing feature of schizophrenia, which has a complex history and has been given a variety of definitions. Currently, insight is measured and treated as a multidimensional phenomenon, because it is believed to result from psychological, neuropsychological and organic factors. Thus, schizophrenia patients may display dramatic disorders including demoralization, depression and a higher risk of suicide, all of which are directly or indirectly related to a lack of insight into their illness, and make the treatment difficult. To improve the treatment of people with schizophrenia, it is thus crucial to advance research on insight into their illness. Insight is studied in a variety of ways. Studies may focus on the relationship between insight and psychopathology, may view behavioral outcomes or look discretely at the cognitive dysfunction versus anatomy level of insight. All have merit but they are dispersed across a wide body of literature and rarely are the findings integrated and synthesized in a meaningful way. The aim of this study was to synthesize findings across the large body of literature dealing with insight, to highlight its multidimensional nature, measurement, neuropsychology and social impact in schizophrenia. The extensive literature on the cognitive consequences of lack of insight and the contribution of neuroimaging techniques to elucidating neurological etiology of insight deficits, is also reviewed.

Previous schizophrenia research suggests poor cognitive control is associated with schizophrenia speech symptoms. However, cognitive control is a broad construct. Two important cognitive control components are poor goal maintenance and poor verbal working memory storage. In the current research, people with schizophrenia (n=45) performed three cognitive tasks that varied in their goal maintenance and verbal working memory storage demands. Speech symptoms were assessed using clinical rating scales, ratings of disorganized speech from typed transcripts, and self-reported disorganization. Overall, alogia was associated with both goal maintenance and verbal working memory tasks. Objectively rated disorganized speech was associated with poor goal maintenance and with a task that included both goal maintenance and verbal working memory storage demands. In contrast, self-reported disorganization was unrelated to either amount of objectively rated disorganized speech or to cognitive control task performance, instead being associated with negative mood symptoms. Overall, our results suggest that alogia is associated with both poor goal maintenance and poor verbal working memory storage and that disorganized speech is associated with poor goal maintenance. In addition, patients' own assessment of their disorganization is related to negative mood, but perhaps not to objective disorganized speech or to cognitive control task performance.

Abstract
Few methods are available to explore the impact of neurocognition in schizophrenia on behaviors performed in usual contexts. The authors developed a video ethnography approach to examine the relationship between naturalistic behaviors and research constructs of neurocognition. Video ethnographers accompanied subjects through usual routines gathering continuous video data. Researchers developed codes to measure four behavioral domains observed on video. This paper describes the psychometric characteristics to be considered in the development of observational approaches. It also highlights differences between behaviors performed in usual environments and neuropsychological constructs. The authors demonstrate that everyday behaviors that have been shown to correspond to neurocognitive skills in a pilot feasibility study can be identified and rated. They further suggest that observational methods could provide novel strategies for linking research findings and clinical concerns.

The Measure of Insight into Cognition: reliability and validity of clinician-rated and self-report scales of neurocognitive insight for schizophrenia. Schizophr Res 2012; 134:54-8. [PMID: 22036020 DOI: 10.1016/j.schres.2011.10.002] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2011] [Revised: 09/27/2011] [Accepted: 10/03/2011] [Indexed: 11/23/2022]
Abstract
Poor insight into the neurocognitive deficits in schizophrenia-spectrum disorders may have significant clinical implications for treatment. The purpose of this study was to replicate and extend the psychometric findings initially reported on the Measure of Insight into Cognition Clinician-Rated (MIC-CR) and Self-Report (MIC-SR) which assess awareness, attribution, and frequency of neurocognitive deficits. Assessments conducted one week apart allowed for internal consistency, test-retest reliability, concurrent validity, and administration order effects to be determined. In this study sample (N=80), 73 demonstrated significant neurocognitive impairment, yet on the MIC-CR, the average awareness and attribution scores indicated only partial awareness and attribution of neurocognitive deficits. The average MIC-SR score indicated rare frequency of cognitive difficulty in everyday life. Cronbach's alphas for the MIC-CR (0.83) and MIC-SR (0.93) were consistent with the initial validation study; test-retest reliability for both MIC assessments was significant (p<0.001). In new analyses, concurrent validity was demonstrated by significant correlations between the MIC-CR and MIC-SR in the first validation sample: r=-0.75 (p<0.001) and the current replication sample: r=-0.70 (p<0.001). Effect sizes were large when frequencies of neurocognitive complaints (MIC-SR) were compared between subjects with good versus poor awareness on the MIC-CR. Reliability and concurrent validity results were similar and significant regardless of order of MIC-CR and MIC-SR administration. The MIC-CR and MIC-SR are thus reliable and valid complementary instruments to assess neurocognitive insight in people with schizophrenia spectrum disorders.
