Psychiatry and Mental health - Abstract
The authors characterized hearing loss among individuals diagnosed as having schizophrenia to inform provision of routine behavioral health services to this population.Audiometry data collected between October 2019 and December 2021 from 84 community-dwelling adults with schizophrenia and 81 age-matched participants without the condition were analyzed. Rates of hearing loss were identified within groups and across age decades (20-50 years). Hearing threshold and rates of hearing loss were compared between groups.Participants with schizophrenia had significantly higher mean hearing thresholds (p=0.006), indicating worse hearing. This difference remained significant after controlling for age (p=0.01). A significantly larger proportion of participants with schizophrenia had mild hearing loss (24%) compared with age-matched participants (6%) (pScreening for and detection of hearing loss among adults with schizophrenia may be an unmet need. Hearing loss is a treatable source of cognitive and psychosocial disability, warranting scalable assessment and intervention practices.

Further validation of the MUSIC® Model of Motivation Inventory (MMI) for use in Cognitive Remediation (CR) for schizophrenia is needed. The MMI was compared to the Intrinsic Motivation Inventory - Schizophrenia Research and Perceived Competency Scale following early treatment exposure in a CR clinical trial. MMI Usefulness, Success, and Interest scales were significantly correlated with corresponding comparison scales. The MMI was not correlated with pre-morbid cognitive ability. Higher expectancy for success and perceived usefulness were significantly associated with greater intensity of session attendance. Results support the convergent, divergent, and predictive validity of the MMI for CR research and clinical use.

To date, no measures are available that permit differentiation of discrete, clinically distinct subtypes of schizophrenia (SZ) with potential differential underlying pathophysiologies. Over recent years, there has been increasing recognition that SZ is heterogeneously associated with deficits in early auditory processing (EAP), as demonstrated using clinically applicable tasks such as tone-matching task (TMT). Here, we pooled TMT performances across 310 SZ individuals and 219 healthy controls (HC), along with clinical, cognitive, and resting-state functional-connectivity MRI (rsFC-MRI) measures. In addition, TMT was measured in a group of 24 patients at symptomatic clinical high risk (CHR) for SZ and 24 age-matched HC (age range 7–27 years). We provide the first demonstration that the EAP deficits are bimodally distributed across SZ subjects (P d = 2.1) and SZ-EAP+ patients (d = 3.4). The SZ-EAP− group predominated among samples drawn from inpatient sites, showed higher levels of cognitive symptoms (PANSS), worse social cognition and a differential deficit in neurocognition (MATRICS battery), and reduced functional capacity. rsFC-MRI analyses showed significant reduction in SZ-EAP− relative to controls between subcortical and cortical auditory regions. As opposed to SZ, CHR patients showed intact EAP function. In HC age-matched to CHR, EAP ability was shown to increase across the age range of vulnerability preceding SZ onset. These results indicate that EAP measure segregates between discrete SZ subgroups. As TMT can be readily implemented within routine clinical settings, its use may be critical to account for the heterogeneity of clinical outcomes currently observed across SZ patients, as well as for pre-clinical detection and efficacious treatment selection.

BackgroundCollaborative data sharing between research groups provides an opportunity to explore the basis for the heterogeneity in cognitive training outcomes reported in the schizophrenia literature. The current analyses focused on the contribution of site and participant characteristics to these heterogeneous outcomes.MethodsData from two independent studies, from New York (NY) and Los Angeles (LA), were combined to yield a sample of 132 outpatient adults with schizophrenia/schizoaffective disorder. While similar treatment doses, cognitive exercises and outcome measures were used, sites differed in use of coaching, group discussion and compensation. Between-site differences in participant demographic and baseline clinical characteristics were tested. Regression examined predictors of change in cognition (MCCB) and functional capacity (UPSA) which could explain site differences in treatment effects.ResultsMedium to large treatment effect size differences in MCCB and UPSA favored the NY site over LA. When the studies were combined, the effect of site was significant for both outcomes with a medium effect size difference. After controlling for background characteristics, the effect of site was reduced for both outcomes, but remained significant for cognition. Improvement in UPSA was associated with better baseline MCCB (p

Cognitive remediation (CR) is an evidence-based therapy used to improve cognition in people with schizophrenia. However, it often requires multiple in-person clinic sessions per week, which can limit scalability. This mixed methods study considered the feasibility and acceptability of a hybrid approach, which allowed for half the sessions to be conducted remotely as homework, without the clinician present. Individuals with schizophrenia were randomized to either all in-clinic or hybrid conditions and completed questionnaires and individual interviews about their experience. CR clinicians provided feedback in complement. Because of limited access to technology, most Hybrid CR participants had to come to clinic to access computers and often sought clinician support to do their homework. Participants in the two conditions were equally satisfied per the Client Satisfaction Questionnaire, and the majority reported perceived benefit and enjoyment. Both CR participants and clinicians identified access to technology as a barrier to program feasibility, while availability of clinician support positively impacted acceptability. Suggestions to improve CR highlighted adopting a flexible approach to providing CR that accounts for participant access to technology, potential benefit from peer interaction, and need for clinician support.

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.

Introduction The COVID-19 crisis and subsequent stay-at-home orders have produced unprecedented challenges to the dissemination of recovery oriented behavioral health services (RS) that support the treatment of those with complex psychosis (CP).This population has typically been managed with in-person pharmacotherapy and/or RS, with the goals of relieving symptoms, improving life satisfaction and increasing community engagement. COVID-19 related social distancing measures have required rapid shifts in care management, while easing of telehealth regulations has allowed for flexibility to approach RS differently. It is essential to learn from the RS telemedicine implementation experience, so that RSs can maintain care for this vulnerable and needy population. Method This paper describes the successful telehealth conversion of a NYC-based, university affiliated RS that serves adults with severe mental illnesses (SMI; n = 64). Results focus on the telehealth acceptance rates of the subset of participants with CP (n = 23). Results The RS continued providing services including intake, care coordination, group psychotherapies, skills training groups, individual skills coaching, and vocational/educational supports. The telehealth conversion rates of the CP subsample indicated that 90% of CP patients accepted telehealth sessions and maintained their specific treatment plans in the virtual format. Mean comparisons between session attendance and cancellations/no-shows during the six-week period before and after telehealth conversion showed no significant differences in service utilization. Discussion RSs play an essential role in the treatment of CP and telehealth may prove to be a viable format of care delivery even after the COVID-19 crisis subsides. The multiple factors in the inner and outer treatment setting that contributed to successful conversion to telehealth will be considered along with the challenges that clinicians and patients encountered.

Cognitive dysfunction is common in psychotic disorders and significantly contributes to difficulty functioning in the home, and in therapeutic, social, educational, and occupational venues. Cognitive remediation is a behavioural treatment used to improve cognition, so people can function better in their life roles. In this chapter, we provide a brief overview of cognition in people with schizophrenia spectrum disorders, how cognition relates to their everyday functioning, and the approaches used in cognitive remediation to improve cognition. We focus on the literature supporting the impact of cognitive remediation on functional outcome, and examine the factors recognised to maximise therapeutic outcome. Finally, we consider some of the challenges and opportunities that arise when implementing cognitive remediation in mental health service settings.

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 < 0.05). 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 = 0.0025), it was intrinsic motivation measured at end-point that was associated with cognitive change (p = 0.02). 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.

Cognitive impairments are common in homeless youth, and negatively impact academic and vocational outcomes. We examined the feasibility and efficacy of cognitive interventions provided to 18–22 year-old homeless youth living in urban supportive housing. Ninety-one homeless youth were randomized to receive either targeted cognitive training (cognitive remediation) or general cognitive activation (computer skills training). Cognitive and psychological outcomes were assessed at baseline, after 13 and 26 sessions, and one month post-intervention. A high drop-out rate highlighted the feasibility challenges of treating this population. Intent-to-treat analysis found significant improvements across groups in specific and global measures of cognition and psychological distress, with no significant group differences. Transition-age homeless youth show improvements in cognitive and psychological functioning when engaged in interventions that address their cognitive development. This speaks to the malleability of cognitive skills in this cohort and lays the groundwork for future research to address their cognitive health.

Cognitive remediation is now widely recognized as an effective treatment for cognitive deficits in schizophrenia. Its effects are meaningful, durable, and related to improvements in everyday functional outcomes. As with many therapies, the evolution of cognitive remediation has resulted in treatment programs that use a variety of specific techniques, yet share common core principles. This paper is the product of a cognitive remediation expert working group consensus meeting to identify core features of the treatment and produce recommendations for its design, conduct, reporting, and implementation. Four techniques were identified as core features of cognitive remediation: facilitation by a therapist, cognitive exercise, procedures to develop problem-solving strategies, and procedures to facilitate transfer to real world functioning. Treatment techniques within each of these core features are presented to facilitate decisions for clinical trials and implementation in clinical settings.

Background Early auditory processing (EAP) has increasingly become a focus of efforts to identify biomarkers of treatment response in schizophrenia. EAP deficits lead to poor functional outcome via impaired cognition, and treatments that target EAP may drive downstream cognitive improvements. Assessment of baseline need provides an opportunity for cognitive remediation (CR) programs that give EAP training to personalize treatment and optimize its impact. This initial efficacy study examined the differential benefit of EAP training for those with and without baseline EAP deficits as defined by performance on the Tone Matching Test. Methods 103 outpatient adults diagnosed with schizophrenia or schizoaffective disorder were classified as having intact (48.5%) or impaired (51.5%) EAP and randomized to a CR program with restorative exercise plans that either included EAP training (N = 49) or did not (N = 54). Cognitive and functional outcomes were measured post-treatment and 3 months later. Results Only in EAP impaired participants was there a significant benefit from EAP training on verbal learning. Treatment condition did not significantly impact global cognitive or functional outcomes for either EAP group. Cognitive gains partially mediated the relationship between gains in EAP and functional capacity. Conclusion These findings support the importance of addressing basic auditory deficits when attempting to remediate higher order auditory impairments such as verbal learning. In addition, they highlight the need for routine assessment of EAP in cognitive remediation participants, as well as the need for more effective programs to reverse these impairments.

Cognitive remediation (CR) research typically addresses internal validity, and few studies consider CR in a real-world context. This study evaluated the fit between the program conditions and treatment model in research and clinical settings, with the goal of informing future research on the contextual challenges associated with the implementation of CR. Data was drawn from an initiative by New York State's Office of Mental Health (OMH), to implement CR programs for adults with Serious Mental Illness (SMI) in 16 state operated outpatient clinics. One of these clinics first became a research site for a CR randomized clinical trial, which allowed for a comparison of the feasibility and acceptability of CR in a research as compared to a clinical setting. RESULTS: The research site averaged almost triple the number of referrals as the clinical sites. Over nine months 46.51% of clinic referrals were enrolled in the CR program whereas 64.29% of research referrals were enrolled. Clinical site utilization averaged 70.53% while research site utilization averaged 90.47%. At the clinical sites, 97% of respondents reported CR was an excellent or good experience. There was high treatment fidelity for program structure and content across sites. CONCLUSIONS: This comparison of CR in clinical and research sites highlights the decrease in referrals, enrollment and utilization that occurs when a program moves from a highly controlled setting to the real world. Still, the acceptability, fill rates and utilization indicated that CR can be successfully implemented in large scale, geographically diverse, publically funded clinic settings.

IntroductionWith the increasing enthusiasm to provide cognitive remediation (CR) as an evidence-based practice, questions arise as to what is involved in implementing CR in a large system of care. This article describes the first statewide implementation of CR in the USA, with the goal of documenting the implementation issues that care providers are likely to face when bringing CR services to their patients.MethodsIn 2014, the New York State Office of Mental Health set up a Cognitive Health Service that could be implemented throughout the state-operated system of care. This service was intended to broadly address cognitive health, to assure that the cognitive deficits commonly associated with psychiatric illnesses are recognized and addressed, and that cognitive health is embedded in the vocabulary of wellness. It involved creating a mechanism to train staff to recognize how cognitive health could be prioritized in treatment planning as well as implementing CR in state-operated adult outpatient psychiatry clinics.ResultsBy 2017, CR was available at clinics serving people with serious mental illness in 13 of 16 adult Psychiatric Centers, located in rural and urban settings throughout New York state. The embedded quality assurance program evaluation tools indicated that CR was acceptable, sustainable, and effective.ConclusionsCognitive remediation can be feasibly implemented in large systems of care that provide a multilevel system of supports, a training program that educates broadly about cognitive health and specifically about the delivery of CR, and embedded, ongoing program evaluation that is linked to staff supervision.

Aim Low motivation is a core symptom of schizophrenia which significantly impacts successful engagement in and benefit from psychosocial treatments. Therefore, it is important for clinicians to design psychosocial treatments to effectively motivate and engage patients during the treatment. The MUSIC® Model of Academic Motivation Inventory (MMI) is an 18-item instrument with five scales that assess students' motivation during academic tasks. The objective of the current study was to validate the MMI for use with schizophrenia-spectrum patients undergoing cognitive training. Methods Participants included 181 people with schizophrenia spectrum disorders enrolled in cognitive training in four countries. A confirmatory factor analysis (CFA) assessed construct validity. Quality of fit was determined using the Comparative Fit Index (CFI), the Standardized Root Mean Square Residual (SRMR), and the Root Mean Square Error of Approximation (RMSEA). Pearson's correlation coefficients assessed construct validity and Cronbach's alphas assessed reliability. Furthermore, we examined factor loadings for each inventory item and assessed predictive validity by analyzing MMI scales with attendance outcomes. Results Consistent with the original MMI validation studies used in academic settings, we found CFI values indicated a good fit, as did the SRMR and RMSEA values. The scales were correlated yet distinct. Cronbach's alpha values ranged from good to excellent and factor loadings showed that all items loaded very well onto their intended factors. The MMI had a positive relationship to treatment intensity. Conclusion The MMI is a valid and reliable tool to use with individuals with schizophrenia spectrum disorders undergoing a cognitive training intervention.

Depressed mood is prevalent among individuals with schizophrenia, leading to difficulties in functioning. Typically, depressed mood is evaluated using retrospective assessments during which individuals are asked to recall their mood during the past week or month. However, as individuals with schizophrenia may display memory difficulties, the results of such assessments may be biased, potentially leading to inaccurate clinical characterizations and/or suboptimal treatment. Our aim was to assess the potential impact of long-term memory on depressed mood in individuals with schizophrenia. Employing an Experience Sampling Method (ESM) approach, 51 individuals with schizophrenia and 22 healthy controls rated their momentary emotions up to 10 times/day over a two-day period, along with retrospective measures of depressed mood, long-term memory, quality of life, social functioning, and symptoms. ESM assessment of real-time depressed mood demonstrated discriminant and convergent validity. Among the schizophrenia group, there was a significant correlation between the real-time and retrospective measures of depressed mood. However, once variance due to long-term memory was controlled, the relationship between the real-time and retrospective measure was no longer significant. The findings suggest that a real-time measure of depressed mood may allow overcoming some of the limitations associated with long-term memory difficulties common among individuals with schizophrenia.

Impairment in cognition is a prevalent and functionally significant symptom in people with serious and persistent mental illness who reside in rehabilitative residential settings. Difficulties in information processing may limit the extent to which an individual with serious and persistent mental illness will be able to meet their personal recovery goals, thus indicating a need for specialized intervention. Cognitive remediation (CR) is a behavioral treatment that directly targets the cognitive skills that have been empirically linked to functional skills and community outcomes. Residential programs offer a therapeutic milieu that is amenable to integrating CR using the treatment parameters that have been identified in empirical studies as contributing to CR efficacy. This article describes potential barriers to CR implementation and how those barriers can be overcome—optimally supporting residents’ ability to learn the skills critical for meeting functional goals and for supporting personal recovery.

BACKGROUND AND OBJECTIVES:There is increasing recognition of the cognitive consequences of socioeconomic adversity during childhood, which can impair learning and negatively affect social and emotional development. However, there is a paucity of research on cognitive functioning and mental health among transition-age homeless youth. This study aimed to address this knowledge gap by examining the prevalence and functional significance of cognitive impairment and mental health disorders in a sample of 18- to 22-year-old homeless youth.METHODS:Participants (N = 73) were recruited from a vocational support program at Covenant House New York, a care agency for homeless youth. Assessments included diagnostic assessment for mental health disorders and evaluation of neurocognition and vocational outcomes.RESULTS:Youth demonstrated histories of academic instability, academic achievement below expectation, and high rates of untreated psychiatric disorders, the most prominent of which were anxiety, substance use, and mood disorders. Of those who had a mental health diagnosis, more than half demonstrated cognitive deficits. Performance on measures of working memory and verbal memory was CONCLUSIONS:These data confirm the need to focus on cognitive as well as emotional and physical health in transition-age youth. Comprehensive intervention at this later developmental stage has the potential to facilitate the acquisition of skills needed for academic, vocational, and independent living success in adulthood.

BACKGROUND: Schizophrenia is associated with cognitive deficits that negatively impact essential areas of daily functioning. Evidence of learning-dependent plasticity in the distributed neural systems that underlie perception and cognition has opened up a burgeoning field of research in cognitive remediation (CR). While the aggregate literature on CR for schizophrenia indicates moderate effect for cognitive and functional outcomes, questions about personalized delivery and essential training elements remain. These shortcomings have constrained the translation of CR research into practical application. Baseline early auditory processing (EAP) holds promise as a way to personalize treatment for the cognitive deficits in schizophrenia. EAP deficits are present in about half of diagnosed patients and are associated with poor functional outcome via impaired cognition. Results of CR studies that target EAP have been mixed, possibly because a systematic method of identifying who needs EAP training was not utilized. Further, not all CR programs- even those that provide restorative, hierarchically organized cognitive training exercises- provide EAP training. Some begin training at the level of attention or even proceed directly to training problem solving and other higher order cognitive abilities. Baseline assessment of EAP could optimize CR outcomes by personalizing treatment of EAP to need. This study examined the differential benefit of EAP training for those with and without baseline EAP deficits as defined by performance on the Tone Matching Test. METHODS: 103 outpatients aged 18–65, diagnosed with schizophrenia spectrum disorder, were first classified as having intact (48.5%) or impaired (51.5%) EAP and then randomized to a CR program with restorative exercise plans that either included EAP training (N=49) or did not (N=54). Cognitive and functional outcomes were measured with the MCCB and UPSA B post 30 sessions treatment and 3 months later. RESULTS: Only the EAP impaired (EAP-) group had significant benefit from EAP training on verbal learning, with moderate treatment effect sizes (0.46) for overall cognition. Treatment condition did not significantly impact functional outcomes for either EAP group. Whereas both EAP- and EAP+ subgroups showed similar Number Needed to Treat (NNT) for functional outcome (1.3 and 1.5 respectively) the NNT for cognitive gain was less than half for the EAP- (2.4) compared to the EAP+ (6.0). Post CR, change in EAP had a significant effect on change in functional outcome (β = 0.878, p

Cognitive deficits are a prominent and enduring aspect of schizophrenia, which pose a significant barrier to achieving functional goals. The most promising intervention for treating cognitive impairment is cognitive remediation (CR), a behaviorally based therapy associated with medium effect sizes for cognitive and functional outcomes. However, there is a sizeable group of nonresponders whose CR outcomes become limited when the therapeutic approach fails to address individual differences in baseline cognition, motivation variables, and the extent to which CR offers opportunities for generalization. This speaks to a need to develop cognitive interventions that are both personalized and scalable. Emerging data suggest that specific pharmacological agents have the potential to enhance and accelerate behaviorally based CR effects. This article will review the rationale and preliminary evidence to support combining CR and pharmacotherapy. We will review crucial aspects of cognitive interventions that offer the most promise for improving not only cognitive outcomes, but also for enhancing improvement in real-world functioning. Finally, we will address methodological issues to be considered for future research on combined pharmacological and CR interventions.

Cognitive deficits are a well-recognised issue for individuals diagnosed with schizophrenia spectrum disorders. Despite positive group findings for the use of cognitive remediation (CR) interventions, there are substantial individual differences in response to treatment. In addition, the aggregate CR literature reports low moderate effect sizes for cognitive and functional outcomes. Based on personalised medicine theory, this paper uses extant CR literature to examine the individual characteristics determined to predict treatment response. These characteristics, which fall into the broad categories of cognitive, psychological, and biological can be used as tailoring variables to personalise CR to an individual's unique profile. Personalisation through the use of these tailoring variables has the potential to improve the delivery of CR to maximise treatment outcomes.

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.

Even when people with schizophrenia describe themselves as generally motivated and eager to engage in activities, they may not actually be motivated in the present moment. In order to better understand the relationship between trait and state motivation, we aimed to assess trait motivation and state intrinsic motivation, and investigate their relations to each other and to criterion-related variables including cognition, negative symptoms, and beliefs about one's own competency-also known as perceived competency (PC). Further, we investigated whether PC mediates the relationships between state intrinsic motivation (IM) and trait motivation dimensions. Forty individuals with schizophrenia or schizoaffective disorders were administered two self-report measures of motivation, the Motivational Trait Questionnaire (Kanfer, R., Ackerman, P., 2000. Individual differences in work motivation: further explorations of a trait framework. Appl. Psychol. 49 (3), 470-482) and the Intrinsic Motivation Inventory for Schizophrenia Research (Choi, J., Medalia, A., 2010. Intrinsic motivation and learning in a schizophrenia spectrum sample. Schizophr. Res. 118, 12-19), as well as measures of PC, cognition and symptoms. The results showed that in people with schizophrenia, trait approach motivation, but not trait avoidance motivation, is positively correlated with state intrinsic motivation and PC. There was evidence that PC partially mediates the relationship between trait approach motivation and state intrinsic motivation to do the task. These results support the role of therapies that directly address self-competency beliefs and set the groundwork for future investigations on the impact of such treatments on motivation.

Cognitive remediation is a behaviorally based training intervention that aims to improve cognitive deficits that impose a significant barrier to everyday functioning. Cognitive remediation for schizophrenia is based on principles of neuroplasticity, and methods of treatment are informed by rehabilitation psychology, neuropsychology and increasingly by theories of motivation. On the whole, cognitive remediation for schizophrenia is shown to improve neurocognition and psychosocial outcomes with effect sizes in the moderate range. Accumulating data indicate that treatment intensity and treatment setting moderate outcomes, and instructional techniques that enhance intrinsic motivation for learning promote engagement, facilitate learning and augment sustained learning outcomes. This article reviews these techniques, drawing from empirical data, and proposes future directions for research in order to further augment treatment outcomes and help people with schizophrenia better achieve their personal goals for recovery.

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

Intrinsic motivation is a construct commonly used in explaining goal-directed behavior. In people with schizophrenia, intrinsic motivation is usually subsumed as a feature of negative symptoms or underlying neurocognitive dysfunction. A growing literature reflects an interest in defining and measuring motivational impairment in schizophrenia and in delineating the specific role of intrinsic motivation as both an independent predictor and a mediator of psychosocial functioning. This cross-sectional study examined intrinsic motivation as a predictor of vocational outcomes for 145 individuals with schizophrenia and schizoaffective disorder participating in a 6-month work rehabilitation trial. Correlation and mediation analyses examined baseline intrinsic motivation and negative symptoms in relation to work hours and work performance. Data support a significant relationship between intrinsic motivation and negative symptoms and significant correlations with outcome variables, such that lower negative symptoms and greater intrinsic motivation were associated with better work functioning. Moreover, in this sample, intrinsic motivation fully mediated the relationships between negative symptoms, work productivity, and work performance. These results have significant implications on the design of work rehabilitation interventions for people with schizophrenia and support a role for targeting intrinsic motivation directly to influence vocational functioning. Future directions for research and intervention are discussed.

Motivation impairment is an often prominent component of schizophrenia symptomatology that impacts treatment engagement and reduces the functional benefit from psychosocial interventions. Intrinsic motivation in particular has been shown to be impaired in schizophrenia. Nowhere is the role of intrinsic motivation impairment more evident than in cognitive remediation for schizophrenia. This chapter describes the theoretical determinants of motivation to learn and illustrates how those determinants have been translated into therapeutic techniques that enhance intrinsic motivation in a clinical context. We review the extant research that indicates how motivation enhancing techniques yield treatment-related improvements within cognitive remediation therapy and, more broadly, in other behavioral skills-based interventions for schizophrenia.

Schizophrenia is associated with severe neurocognitive deficits that constitute a core feature of the disorder. Deficits have been most extensively studied in relationship to higher-order processes. This study evaluated the integrity of early visual processing in order to evaluate the overall pattern of visual dysfunction in schizophrenia. Steady-state visual-evoked potentials (ssVEPs) were recorded over the occipital cortex (Oz) in patients with schizophrenia and schizoaffective disorder (N=26) and in age-matched comparison volunteers (N=22). Two stimuli were used: windmill-dartboard and partial-windmill, which are contrast-reversing ( approximately 4 Hz), radial patterns with dominant low spatial-frequency content. Each stimulus was presented for 1 min. Fourier analysis was performed on the ssVEP data to extract the relevant temporal frequency (i.e., harmonic) components. Magnitude-squared coherence (MSC) was computed to estimate the relative signal level for each frequency component. The patients showed reduced amplitude and coherence of second harmonic responses in both conditions, but intact first harmonic responses in the windmill-dartboard condition. This finding of a differential deficit may indicate a significant loss in the magnocellular pathway, which contributes to the generation of the second harmonic component under these conditions. Early sensory deficits may lead to impairments in subsequent stages of processing.

Background Deficits in affect recognition are prominent features of schizophrenia. Within the auditory domain, patients show difficulty in interpreting vocal emotional cues based on intonation (prosody). The relationship of these symptoms to deficits in basic sensory processing has not been previously evaluated. Methods Forty-three patients and 34 healthy comparison subjects were tested on two affective prosody measures: voice emotion identification and voice emotion discrimination. Basic auditory sensory processing was measured using a tone-matching paradigm and the Distorted Tunes Test (DTT). A subset of subjects was also tested on facial affect identification and discrimination tasks. Results Patients showed significantly impaired performance on all emotion processing tasks. Within the patient group, a principal components analysis demonstrated significant intercorrelations between basic pitch perception and affective prosodic performance. In contrast, facial affect recognition deficits represented a distinct second component. Prosodic affect measures correlated significantly with severity of negative symptoms and impaired global outcome. Conclusions These results demonstrate significant relationships between basic auditory processing deficits and impaired receptive prosody in schizophrenia. The separate loading of auditory and visual affective recognition measures suggests that within-modality factors may be more significant than cross-modality factors in the etiology of affect recognition deficits in schizophrenia.

Background Schizophrenia is a neurocognitive disorder with a wide range of cognitive and sensory impairments. Early visual processing has been shown to be especially impaired. This article investigates the integrity of binocular depth perception (stereopsis) in schizophrenia. Methods Seventeen schizophrenia patients and 19 healthy control subjects were compared on the Graded Circles Stereo Test. Results of stereoacuity were compared between patients and control subjects using t test. Results Schizophrenia patients demonstrated significantly ( p = .006) reduced stereoacuity (mean = 142 arcseconds) versus control subjects (mean = 55 arcseconds). At the normative level for adults, patients performed below chance. Conclusions These findings demonstrate an impairment of binocular depth perception and further confirm deficits of early visual processing in schizophrenia. Findings are discussed in context of magnocellular/dorsal stream processing with implications for visual processing and cognitive deficits.

Cognitive remediation (CR) for schizophrenia is a learning-based behavioural skills training intervention designed to enhance neuro and (or) social cognitive skills, with the ultimate goal of generalization to improve psychosocial outcomes. This review summarizes conceptual approaches to CR for schizophrenia and the evidence for efficacy in clinical research settings. Four issues are at the forefront of ongoing research: the identification of techniques that produce the largest cognitive change, delineation of techniques that enhance transfer of cognitive skills to functional skills, the identification of CR methods that can be personalized to meet the specific cognitive and functional needs of each individual, and, all the while, ensuring that when CR methods are developed in a research setting, they remain scalable for delivery in the larger clinical community. In response to these issues, 3 prominent research trends have emerged: the rise of a new generation of computerized restorative cognitive training, the integration of CR with skills training to promote generalization, and the application of techniques to enhance motivation and learning during CR. As data on the neural basis of learning in people with schizophrenia become available, new technologies that harness the ability of the brain to make sustainable, functional changes may be integrated within a therapeutic context that promotes a personalized approach to learning. The development of transportable and scalable methods of CR that maximize the ability of people with schizophrenia to improve cognition will help them achieve personal goals for recovery.La rééducation cognitive (RC) pour la schizophrénie est une intervention de formation comportementale par l’apprentissage, destinée à améliorer les aptitudes cognitives neuro et (ou) sociales, dans un but final de généralisation afin d’améliorer les résultats psychosociaux. Cette étude résume les approches conceptuelles de la RC pour la schizophrénie et les données probantes d’efficacité dans des contextes de recherche clinique. Quatre questions sont à l’avant-plan de la recherche en cours : l’identification des techniques qui produisent le plus grand changement cognitif, la délimitation des techniques qui améliorent le transfert des aptitudes cognitive s aux aptitudes fonctionnelles, l’identification des méthodes de RC qui peuvent être personnalisées pour répondre aux besoins cognitifs et fonctionnels spécifiques de chaque personne, et, pendant ce temps, faire en sorte que les méthodes de la RC soient développées dans un cadre de recherche, qu’elles demeurent évolutives et applicables à la grande communauté clinique. En réponse à ces questions, 3 tendances proéminentes de la recherche se sont dessinées : la montée d’une nouvelle génération de formation cognitive restauratrice informatisée, l’intégration de la RC avec la formation axée sur les aptitudes pour promouvoir la généralisation, et l’application de techniques qui améliorent la motivation et l’apprentissage durant la RC. À mesure que paraissent les données sur le fondement neuronal de l’apprentissage chez les personnes souffrant de schizophrénie, les nouvelles technologies qui captent la capacité du cerveau d’effectuer des changements fonctionnels durables peuvent être intégrées à un contexte thérapeutique qui favorise une approche personnalisée de l’apprentissage. Le développement de méthodes de RC transportables et évolutives qui maximisent la capacité des personnes souffrant de schizophrénie d’améliorer leur cognition les aidera à atteindre leurs objectifs personnels de rétablissement.

Purpose of review Cognitive deficits are recognized as key determinants of functional outcome in schizophrenia. Cognitive remediation for schizophrenia, which is intended to improve both cognition and functional outcome, has been shown to impact cognition regardless of quality of trial methodology used. However, the impact of cognitive remediation on functional outcomes is more variable. A number of recently published articles specifically address the issues impacting the effectiveness of cognitive remediation at improving psychosocial outcomes. Recent findings In this review, studies published since 2011 have been summarized, with a particular focus on psychosocial outcomes. Cognitive remediation may include a focus on neurocognition and/or social cognition, but is increasingly integrative, targeting a range of cognitive skills. Psychosocial outcomes include quality of life, employment outcomes, academic functioning, and social functioning. Summary The reviewed literature indicates that cognitive remediation is most likely to impact functional outcome when individuals are given opportunities to practice the cognitive skills in real-world settings. By integrating a cognitive remediation program with psychosocial rehabilitation programs, functional outcomes are enhanced. Cognitive remediation programs that do not solely rely on drill and practice, but instead incorporate strategy teaching and methods to address beliefs and motivation, are associated with better psychosocial outcomes.

Objective: High rates of smoking and nicotine dependence have a profoundly negative impact on the health and well being of individuals with schizophrenia. Treating smoking is a critical step in improving the health and quality of life of people affected by this illness. This paper reviews the literature on smoking cessation interventions in schizophrenia and discusses potential barriers to effective treatment with this population. Methods: The criteria used to select studies for inclusion were: (1) Sample included 50% or more individuals with schizophrenia spectrum diagnosis (SSD); (2) Some individual or group intervention for smoking cessation was provided; and (3) Some smoking-related outcome variable was measured (self-reported smoking, breath carbon monoxide, etc). Results: Both pharmacologic and psychosocial smoking cessation treatments have been found to be useful in helping individuals with schizophrenia reduce and quit smoking in the short term. Few interventions have been found to be effective in promoting smoking abstinence in the long term. Conclusions: Intervention development must include strategies to overcome barriers to smoking cessation that are most relevant to individuals with schizophrenia and focus on translating short term gains into long term abstinence.

The present study highlights the importance of carefully assessing neuropsychological functioning at the outset of cognitive remediation (CR) treatment. The effects of neuropsychological, psychological, and clinical variables on treatment utilisation (TU) in CR groups for individuals with schizophrenia were examined. Data included neuropsychological and psychosocial assessments conducted with 39 adult clients enrolled in CR as part of their ongoing outpatient therapy. TU was calculated using the percentage of sessions attended over a three-month period. Better global neuropsychological functioning (r = .46, p = .007), attention/working memory (r = .39, p = .03), and processing speed (r = .44, p = .01) were each associated with greater TU. Trend-level associations with TU were observed with executive functioning (r = .33, p = .06) and verbal learning (r = .23; p = .07). Higher rates of self-reported cognitive complaints were associated with lower TU (r = -.45, p = .01). Hierarchical regression analyses revealed that both objective and subjective indicators of neuropsychological functioning independently contributed to the prediction of TU. This information can serve to help providers develop empirically informed strategies to support their clients' CR treatment utilisation. The implications from these findings can be used as a way to provide ongoing guidance for service provision and can aid in improving CR treatment utilisation, and thus treatment effectiveness, in clinical settings.

Learning during skills-based psychosocial treatments for schizophrenia is influenced by the motivating properties of the treatment context and the motivational orientation of the client. Given that motivational impairment is a core feature of schizophrenia with significant functional implications, intervention strategies emphasizing extrinsic and/or intrinsic goals may be prescribed to enhance skill learning and treatment outcomes. The purpose of this article is to consider the role that motivation plays in treatment success by evaluating the relationship between motivation and learning during cognitive remediation for schizophrenia. As intrinsic motivation (IM) is most often associated with learning, we will integrate research findings which address 3 main questions: (1) is IM in schizophrenia static or dynamic, (2) is it possible to manipulate the state of being intrinsically motivated and if so do manipulations of IM affect learning? and (3) can motivation theory be translated into clinical practice? This knowledge can facilitate treatment strategies to address the low base rate of IM that is characteristic of schizophrenia and can be applied to cognitive remediation as well as other psychosocial interventions which require learning for treatment success.

The deficit syndrome is thought to characterize a pathophysiologically distinct subgroup of patients with schizophrenia. Supporting this notion, prior research examining the neuropsychological correlates of the deficit syndrome has suggested the presence of a differential impairment in frontal and parietal functions. This article reports findings from 2 studies attempting to replicate and extend previous reports of a differential neuropsychological impairment in deficit schizophrenia. In the first study, we administered a comprehensive neuropsychological battery to 20 deficit and 25 nondeficit patients with schizophrenia and 25 normal healthy controls. In the second study, a meta-analysis was conducted of 13 separate studies examining the neuropsychology of the deficit syndrome. There was little evidence from either of the present studies that the deficit syndrome is associated with a selective impairment in frontal and parietal lobe functions. The first study failed to find significant differences in frontal or parietal abilities for deficit vs nondeficit patients. The meta-analytic findings revealed that deficit patients were globally more neuropsychologically impaired than nondeficit patients (effect size [ES] = 0.41). Relative to nondeficit patients, deficit patients performed poorest on tests of olfaction (ES = 1.11), social cognition (ES = 0.56), global cognition (ES = 0.52), and language (ES = 0.51). The neuropsychological impairments associated with the deficit form of schizophrenia do not follow an obvious anatomically defined pattern of impairment. The question of whether deficit patients exhibit a unique cognitive impairment profile will require a more sophisticated and rigorous examination of the neuropsychology of the deficit syndrome.

Research suggests that first-degree relatives and individuals with schizophrenia spectrum personality disorders (SSPD) may represent nonpenetrant carriers of the genetic diathesis for schizophrenia. This study examined visuospatial working memory (SWM) as a cognitive endophenotype of schizophrenia by expanding the concept of risk for pathophysiological dysfunction beyond overt psychosis. Risk was thus defined by familial status and the presence or absence of SSPD. SWM was assessed in the following groups, in order of decreasing likelihood of genetic vulnerability: 23 patients with schizophrenia, 17 SSPD relatives of patients with schizophrenia, 23 non-SSPD relatives of patients with schizophrenia, 14 SSPD community members with no family history of psychosis, and 36 non-SSPD community members. SWM performance during a computer task was quantified by A-Prime. Relative risk ratios for SWM deficits were compared among the groups. Compared with community non-SSPD volunteers, relative risk (RR) of SWM deficits was significantly elevated in patients with schizophrenia (RR = 3.76, p = .002) and SSPD family members (RR = 2.97, p = .027), but not in the family non-SSPD (RR = 1.88, p = .241) or community SSPD (RR = 1.03, p = .971) groups. The pattern of SWM performance deficits reflected the proposed model of latent genetic liability, upholding SWM as a viable cognitive endophenotype. The results underscore the importance of including both familial liability and the schizophrenia spectrum when considering risk for schizophrenia and schizophrenia-related traits. This is particularly relevant for research efforts to identify pathophysiological components of the disease.

Social anhedonia has shown promise as a vulnerability marker for schizophrenia-spectrum pathology. Validity data have come, in part, from findings indicating that cognitive deficits occurring in schizophrenia are also evident in individuals with elevated levels of social anhedonia. However, prior research on this topic has been limited because it has been based almost exclusively on the study of selective samples of college students. The present article reports baseline findings of neuropsychological functioning in social anhedonics and controls from a representative community sample. Data on a wide array of neuropsychological abilities from 18-19 year-old participants with (n = 85) vs. without (n = 87) elevated levels of social anhedonia were analyzed. We hypothesized that, compared to controls, social anhedonics would show impairments in memory and sustained attention. Additionally, we sought to determine if more severe cognitive impairment in anhedonics was associated with greater schizophrenia-spectrum pathology and poorer overall functioning. Compared to controls, socially anhedonic participants performed more poorly on two visual-spatial memory tasks and a test of visual-spatial construction. The groups did not statistically differ on any of the other neuropsychological measures including general cognitive ability and sustained attention. Group differences were not the result of depression, bipolar or substance abuse disorders. Neuropsychological functioning showed little relationship to current clinical symptoms and functioning. Longitudinal assessment of these participants as they move through the risk period should provide important insights into the neuropsychological correlates of the schizophrenia prodrome.

Patients with schizophrenia demonstrate significant impairments of early visual processing, potentially implicating dysfunction of the magnocellular visual pathway. The present study evaluates transient visual evoked potential (tVEP) responses to stimuli biased toward the magnocellular (M) or parvocellular (P) systems in patients with schizophrenia vs. normal volunteers first to evaluate relative contributions of M and P systems to specific tVEP components in schizophrenia and, second, to evaluate integrity of early M and P processing in schizophrenia.Seventy-four patients with schizophrenia and schizoaffective disorder were compared with 59 control subjects using separate stimuli to assess the tVEP response to M, P and mixed M/P conditions. Stimuli were biased toward M vs. P processing by manipulation of chromatic and achromatic contrast. C1, P1, N1 and P2 components were compared between patients and controls. All subjects showed 20/32 vision or better.Waveforms were obtained to low contrast (M), chromatic contrast (P) and high contrast (mixed M/P) stimuli in both patients and controls. C1 was present to P and mixed M/P stimuli. Patients showed a significant reduction in amplitude and an increase in latency of the C1 component. P1 was elicited primarily by M and mixed M/P stimuli, whereas N1 was elicited primarily by P and mixed M/P stimuli. Patients showed reductions in both P1 and N1 amplitudes across conditions. However, only reductions in P1 amplitude survived covariation for between group differences in visual acuity. Further, P1 amplitude reductions in the M condition correlated with a proxy measure of global outcome.M- and P-selective stimuli elicit differential components of the tVEP. Patients with schizophrenia show significant reductions in response even to simple visual stimuli. Deficits, particularly within the M system, may correlate significantly with global outcome and level of community functioning.Whereas deficits in high-order cognitive processing have been extensively documented in schizophrenia, integrity of early-stage sensory processing has been studied to a lesser degree. The present findings suggest that deficits in early-stage visual processing are significantly related to overall clinical outcome in schizophrenia. Further, between-group differences in visual acuity may influence VEP results, even for subjects with 'normal' vision (20/32 or better).

Patients with schizophrenia show deficits in early-stage visual processing, potentially reflecting dysfunction of the magnocellular visual pathway. The magnocellular system operates normally in a nonlinear amplification mode mediated by glutamatergic (N-methyl-D-aspartate) receptors. Investigating magnocellular dysfunction in schizophrenia therefore permits evaluation of underlying etiologic hypotheses.To evaluate magnocellular dysfunction in schizophrenia, relative to known neurochemical and neuroanatomical substrates, and to examine relationships between electrophysiological and behavioral measures of visual pathway dysfunction and relationships with higher cognitive deficits.Between-group study at an inpatient state psychiatric hospital and outpatient county psychiatric facilities. Thirty-three patients met DSM-IV criteria for schizophrenia or schizoaffective disorder, and 21 nonpsychiatric volunteers of similar ages composed the control group.(1) Magnocellular and parvocellular evoked potentials, analyzed using nonlinear (Michaelis-Menten) and linear contrast gain approaches; (2) behavioral contrast sensitivity measures; (3) white matter integrity; (4) visual and nonvisual neuropsychological measures, and (5) clinical symptom and community functioning measures.Patients generated evoked potentials that were significantly reduced in response to magnocellular-biased, but not parvocellular-biased, stimuli (P = .001). Michaelis-Menten analyses demonstrated reduced contrast gain of the magnocellular system (P = .001). Patients showed decreased contrast sensitivity to magnocellular-biased stimuli (P.001). Evoked potential deficits were significantly related to decreased white matter integrity in the optic radiations (P.03). Evoked potential deficits predicted impaired contrast sensitivity (P = .002), which was in turn related to deficits in complex visual processing (Por =.04). Both evoked potential (Por =.04) and contrast sensitivity (P = .01) measures significantly predicted community functioning.These findings confirm the existence of early-stage visual processing dysfunction in schizophrenia and provide the first evidence that such deficits are due to decreased nonlinear signal amplification, consistent with glutamatergic theories. Neuroimaging studies support the hypothesis of dysfunction within low-level visual pathways involving thalamocortical radiations. Deficits in early-stage visual processing significantly predict higher cognitive deficits.
