From neurocognition to community participation in serious mental illness: the intermediary role of dysfunctional attitudes and motivation

The role of motivation in clinical presentation, treatment engagement and response in schizophrenia-spectrum disorders: A systematic review

Schizophrenia, a debilitating psychiatric disorder, has a long-term impact on social and occupational functioning. While negative symptoms, notably amotivation, are recognized as poor prognostic factors, the positive force of patient motivation (autonomous motivation) remains underexplored. This systematic review, guided by Self-Determination Theory (SDT), investigated the impact of motivation on clinical presentation, and treatment engagement and response in schizophrenia-spectrum disorders. Fifty-five independent studies (N = 6897), using 23 different motivation scales, met inclusion criteria. Results were categorized into cross-sectional and longitudinal correlates of autonomous motivation, and the effects of motivational interventions. Cross-sectionally, autonomous motivation was positively associated with social/occupational functioning, and negatively associated with negative and positive symptom severity. In longitudinal studies, baseline autonomous motivation predicted engagement in and response to social/occupational treatments, with mixed results in cognitive interventions. In the 16 randomized controlled trials (RCTs), the most common motivational interventions were individualized goal setting and goal attainment support, followed by increasing sense of competence by challenging defeatist beliefs, and enhancing relatedness by increasing contact time. Motivational interventions consistently increased autonomous motivation, treatment engagement and response. More studies are needed, particularly studies that monitor motivation during treatment: proximal assessments could facilitate the identification of treatment elements that impact motivation and engagement and inform treatment modifications to enhance the patient experience and improve treatment efficacy.

The Role of Defeatist Performance Beliefs in State Fluctuations of Negative Symptoms in Schizophrenia Measured in Daily Life via Ecological Momentary Assessment

BACKGROUND AND HYPOTHESIS

The Cognitive Model of Negative Symptoms is a prominent model that posits that defeatist performance beliefs (DPB) are a key psychological mechanism underlying negative symptoms in those with schizophrenia (SZ). However, the ecological validity of the model has not been established, and temporally specific evaluations of the model's hypotheses have not been conducted. This study tested the model's key hypotheses in real-world environments using ecological momentary assessment (EMA).

STUDY DESIGN

Fifty-two outpatients with SZ and 55 healthy controls (CN) completed 6 days of EMA. Multilevel models examined concurrent and time-lagged associations between DPB and negative symptoms in daily life.

STUDY RESULTS

SZ displayed greater DPB in daily life than CN. Furthermore, greater DPB were associated with greater concurrently assessed negative symptoms (anhedonia, avolition, and asociality) in daily life. Time-lagged analyses indicated that in both groups, greater DPB at time t led to elevations in negative symptoms (anhedonia, avolition, or asociality) at t + 1 above and beyond the effects of negative symptoms at time t.

CONCLUSIONS

Results support the ecological validity of the Cognitive Model of Negative Symptoms and identify a temporally specific association between DPB and subsequent negative symptoms that is consistent with the model's hypotheses and a putative mechanistic pathway in Cognitive Behavioral Therapy for negative symptoms. Findings suggest that DPB are a psychological factor contributing to negative symptoms in real-world environments. Implications for measuring DPB in daily life and providing just-in-time mobile health-based interventions to target this mechanism are discussed.

The role of defeatist performance beliefs on cognitive effort-cost decision-making in schizophrenia

Impairments in effort-cost decision-making have been consistently observed in people with schizophrenia (SZ) and may be an important mechanism of negative symptoms. However, the processes that give rise to impairments in effort-cost decision-making are unclear, leading to limited progress in identifying the most relevant treatment targets. Drawing from cognitive models of negative symptoms and goal-directed behavior, this study aimed to examine how and under what type of task conditions defeatist performance beliefs contribute to these decision-making processes. Outpatients with SZ (n = 30) and healthy controls (CN; n = 28) completed a cognitive effort allocation task, the Cognitive Effort-Discounting (COGED) task, which assesses participants' willingness to exert cognitive effort for monetary rewards based on parametrically varied working memory demands (completing N-back levels). Results showed that although participants with SZ demonstrated reduced willingness to work for rewards across N-back levels compared to CN participants, they showed less choice modulation across different N-back conditions. However, among SZ participants with greater defeatist performance beliefs, there was a reduced willingness to choose the high effort option at higher N-back levels (N-back levels 3, 4, and 5 versus 2-back). Results suggest that compared to CN, the SZ group's subjective willingness to expend effort largely did not dynamically adjust as cognitive load increased. However, defeatist beliefs may undermine willingness to expend cognitive effort, especially when cognitive task demands are high. These beliefs may be a viable treatment target to improve effort-cost decision-making impairments in people with SZ.

Towards an integrative hope-dysfunctional beliefs perspective to personal recovery in schizophrenia: a path analysis

BACKGROUND

Evidence shows that negative symptoms of schizophrenia and underlying dysfunctional cognition are related to persistently low functioning and quality of life. However, despite the abundance of existing recovery programs for people with schizophrenia, few have examined whether and how the widely-adopted hope-motivation recovery pathway and the deficit-oriented cognitive pathway might converge to influence functioning and quality of life.

METHODS

A cross-sectional, quantative survey recruited a convenient sample of adult outpatients with DSM-5 schizophrenia spectrum disorders and low social functioning (n = 124). Self-reported measurements included personal recovery (30-item Mental Health Recovery Measure), social functioning (8-item Social Functioning Questionnaire), hope (12-item Hope Scale), quality of life (28-item World Health Organization Quality of Life Scale-Abbreviated Version-Hong Kong), defeatist beliefs (15-item extracted from Dysfunctional Attitude Scale), and asocial beliefs (15-item extracted from Revised Social Anhedonia Scale). Correlation analysis and structural equation modelling was applied to investigate how the two pathways intertwined to predict social functioning and quality of life.

RESULTS

Asocial beliefs and hope separately mediated two partial mediation pathways from defeatist beliefs to recovery outcomes (social functioning and personal recovery). Meanwhile, defeatist beliefs, social functioning, and personal recovery further predicted quality of life.

CONCLUSIONS

This is one of the very few studies that provides empirical evidence of a deficit-strength linkage in the recovery from schizophrenia. Remediation of dysfunctional beliefs and the injection of hope and successful experiences should be undertaken concurrently in recovery as they are associated with differential effects on enhancing social functioning and personal recovery, which then converge and contribute to a better quality of life.

Neurocognition and Depressive Symptoms have Unique Pathways to Predicting Different Domains of Functioning in Major Depressive Disorder

BACKGROUND

Research has established the independent relationships between depressive symptoms to cognition and functioning in depression; however, little is known about the role of mediators in this relationship. We explored the role of neurocognitive abilities, depressive symptom severity, dysfunctional attitudes, and functional capacity in predicting two dimensions of daily functioning in individuals with major depressive disorder (MDD).

METHODS

One hundred and twenty-four participants (mean age  =  46.26, SD  =  12.27; 56% female) with a diagnosis of MDD were assessed on a standard neurocognitive battery, self-reported depressive symptoms, dysfunctional attitudes, and clinician-rated functional impairment. They completed a performance-based assessment of functional competence.

RESULTS

Confirmatory path analyses were used to model the independent and mediated effects of variables on two domains of functioning: social (relationships and social engagement) and productive (household and community activities). Cognition and depressive symptoms both predicted productive functioning, and dysfunctional attitudes mediated each of these relationships. Functional competence was a significant mediator in the relationship between neurocognition and productive functioning. Depressive symptoms and cognition were direct predictors of social functioning with no significant mediators.

CONCLUSIONS

There are divergent pathways to different dimensions of daily functioning in MDD. Measurement implications include the consideration of multiple levels of predicting productive activities and more direct relationships with social outcomes. Treatments that directly target depressive symptoms and cognition might not generalize to improvements in everyday functioning if additional pathways to functioning are not addressed.

The relative contributions of insight and neurocognition to intrinsic motivation in schizophrenia

Intrinsic motivation was described as the mental process of pursuing a task or an action because it is enjoyable or interesting in itself and was found to play a central role in the determination of the functional outcome of schizophrenia. Neurocognition is one of the most studied determinants of intrinsic motivation in clinically stable schizophrenia while little is known about the role of insight. Following this need we decided to focus on the contribution of different aspects of insight and of neurocognition to intrinsic motivation in a large sample (n = 176) of patients with stable schizophrenia. We performed three hierarchical linear regressions from which resulted that, among different insight aspects, the ability to correctly attribute signs and symptoms to the mental disorder made the strongest contribution to intrinsic motivation. Neurocognition, also, was significantly related to intrinsic motivation when analyzed simultaneously with insight. Moreover, even after accounting for sociodemographic and clinical variables significantly correlated with intrinsic motivation, the relationship between insight and neurocognition and intrinsic motivation remained statistically significant. These findings put the emphasis on the complex interplay between insight, neurocognition, and intrinsic motivation suggesting that interventions targeting both insight and neurocognition might possibly improve this motivational deficit in stable schizophrenia should.

Factors Related to Passive Social Withdrawal and Active Social Avoidance in Schizophrenia

ABSTRACT

Social withdrawal in schizophrenia may be a result of "passive" motivation (reduced drive to engage) or "active" motivation (increased drive to avoid). We conducted a cross-sectional, between-subjects study using self-report measures and social cognition tasks to evaluate the relationships between motivational subtypes, social abilities, and social functioning in schizophrenia spectrum (n = 52, ages 19-34). Regression models showed significant differences in passive and active withdrawal. Passive, but not active, motivation predicted social functioning as measured by a clinical interview. This suggests that motivation, especially passive type, plays an important role in social withdrawal in schizophrenia. However, on a self-report measure of social functioning, neither passive nor active motivation predicted outcomes, suggesting a potential disconnect between observer versus self-report measures when assessing social motivation. Furthermore, performance on tasks of social abilities did not predict motivation, which supports the idea that motivation is distinct from social ability and should be specifically addressed in treatment.

Psychological Dimensions Relevant to Motivation and Pleasure in Schizophrenia

Motivation and pleasure deficits are common in schizophrenia, strongly linked with poorer functioning, and may reflect underlying alterations in brain functions governing reward processing and goal pursuit. While there is extensive research examining cognitive and reward mechanisms related to these deficits in schizophrenia, less attention has been paid to psychological characteristics that contribute to resilience against, or risk for, motivation and pleasure impairment. For example, psychological tendencies involving positive future expectancies (e.g., optimism) and effective affect management (e.g., reappraisal, mindfulness) are associated with aspects of reward anticipation and evaluation that optimally guide goal-directed behavior. Conversely, maladaptive thinking patterns (e.g., defeatist performance beliefs, asocial beliefs) and tendencies that amplify negative cognitions (e.g., rumination), may divert cognitive resources away from goal pursuit or reduce willingness to exert effort. Additionally, aspects of sociality, including the propensity to experience social connection as positive reinforcement may be particularly relevant for pursuing social goals. In the current review, we discuss the roles of several psychological characteristics with respect to motivation and pleasure in schizophrenia. We argue that individual variation in these psychological dimensions is relevant to the study of motivation and reward processing in schizophrenia, including interactions between these psychological dimensions and more well-characterized cognitive and reward processing contributors to motivation. We close by emphasizing the value of considering a broad set of modulating factors when studying motivation and pleasure functions in schizophrenia.

Metacognitive Training Modified for Negative Symptoms (MCT-N): A Feasibility study

OBJECTIVE

Although patients often prioritise the treatment of negative symptoms, few psychological interventions targeting negative symptoms exist. This study attempts to fill this gap by piloting a modified Metacognitive training programme, specifically targeted at negative symptoms (MCT-N), with a group of patients with prominent negative symptoms.

METHOD

We adopted a mixed methods case series design, providing detailed quantitative data on changes over time, to focus on potential mechanisms underlying the intervention, in combination with qualitative interviews.

RESULTS

The intervention showed good feasibility as demonstrated by the attendance rate, the positive feedback from participants and the multidisciplinary team, and the improvements on negative symptoms observed following the intervention. Multilevel modelling showed that depression, internalised stigma, and reflective functioning explained the variance in negative symptoms.

DISCUSSION

The pilot study indicated that the intervention has high feasibility and that improvements in negative symptoms can be partially explained by improvements on depression, stigma, and reflective functioning.

Relationship of ventral striatum activation during effort discounting to clinical amotivation severity in schizophrenia

Motivational deficits play a central role in disability due to negative symptoms of schizophrenia (SZ), but limited pathophysiological understanding impedes critically needed therapeutic development. We applied an fMRI Effort Discounting Task (EDT) that quantifies motivation using a neuroeconomic decision-making approach, capturing the degree to which effort requirements produce reductions in the subjective value (SV) of monetary reward. An analyzed sample of 21 individuals with SZ and 23 group-matched controls performed the EDT during fMRI. We hypothesized that ventral striatum (VS) as well as extended brain motivation circuitry would encode SV, integrating reward and effort costs. We also hypothesized that VS hypoactivation during EDT decisions would demonstrate a dimensional relationship with clinical amotivation severity, reflecting greater suppression by effort costs. As hypothesized, VS as well as a broader cortico-limbic network were activated during the EDT and this activation correlated positively with SV. In SZ, activation to task decisions was reduced selectively in VS. Greater VS reductions correlated with more severe clinical amotivation in SZ and across all participants. However, these diagnosis and amotivation effects could not be explained by the response to parametric variation in reward, effort, or model-based SV. Our findings demonstrate that VS hypofunction in schizophrenia is manifested during effort-based decisions and reflects dimensional motivation impairment. Dysfunction of VS impacting effort-based decision-making can provide a target for biomarker development to guide novel efforts to assess and treat disabling amotivation.

Impact of changes in social anxiety on social functioning and quality of life in outpatients with schizophrenia: A naturalistic longitudinal study

The prevalence of comorbid social anxiety disorder among patients with schizophrenia is currently attracting attention, and symptoms of social anxiety are reportedly associated with various clinical features. However, the contribution of social anxiety to social functioning and quality of life (QOL) over time remains obscure. The aim of this study was to examine the impact of changes in social anxiety symptoms on social functioning and QOL among outpatients with schizophrenia. Of the 207 outpatients who were eligible at baseline, 118 patients agreed with and completed a follow-up investigation at least 1 year (695.8 days on average) after the baseline study. Stepwise multiple regressions examining the change in social functioning using demographic data and changes in clinical variables as explanatory variables demonstrated that the changes in social anxiety and general psychopathology contributed to the change in the Social Functioning Scale, while the changes in clinical severity and negative symptoms contributed to the change in the Global Assessment of Functioning scale. Stepwise multiple regressions for the change in QOL demonstrated that the changes in social anxiety and depression contributed to the change in the World Health Organization QOL scale, Brief version, and the changes in social anxiety and positive symptoms contributed to the Subjective Well-being Under Neuroleptic Drug Treatment, Short Form. The results revealed that the changes in social anxiety symptoms were significantly associated with the change in functional outcome among patients with schizophrenia. Treatments targeting social anxiety seem to be key to achieving a full recovery in patients with schizophrenia.

Clarifying the overlap between motivation and negative symptom measures in schizophrenia research: A meta-analysis

Motivation and negative symptom research has recently been hampered by a series of inconsistent findings, leading to calls for a greater consensus on the type of measures used across studies. To inform this issue, we conducted a meta-analysis that quantified the association between motivation measures (self-report, performance-based) and clinician-rated negative symptom measures as well as a series of moderator analyses to develop a greater understanding of the measurement factors impacting this relationship. Forty-seven eligible studies with people with schizophrenia-spectrum disorders were included. Using a random-effects meta-analytic model, a small but significant overall effect size emerged between motivation and clinician-rated negative symptoms (r = -0.18). Several significant moderators were identified, including the generation of negative symptom measures such that there was a significantly stronger relationship between motivation and second-generation (r = -0.38) than first-generation negative symptom measures (r = -0.17). Further, the type of performance-based measure used moderated the relationship, with effort discounting tasks most strongly related to negative symptoms (r = -0.44). The domain of motivation assessed (intrinsic, extrinsic, amotivation) also moderated the relationship. These findings help to identify sources of inconsistencies observed in prior studies and point to both second-generation and effort discounting tasks as the most promising types of measures, particularly for those interested in validating motivation measures or assessing the effectiveness of motivation treatments. Although additional research is needed, our results suggest that using these measures may help to reduce inconsistencies across studies and move the field forward.

Socially Valued Roles, Self-Determination, and Community Participation among Individuals Living with Serious Mental Illnesses

Decades after deinstitutionalization, individuals living with serious mental illnesses remain isolated, socially disengaged, and devalued members of communities. Burgeoning research and services need conceptual clarity to improve such social conditions. This qualitative inquiry used grounded theory and participatory approaches to conduct an in-depth exploration of community participation for individuals living with serious mental illnesses based on key stakeholder perspectives (n = 45). Results revealed that community participation is a multifaceted construct with layers of meaning for individuals living with serious mental illnesses. Overarching themes are contextualized in Self-Determination Theory and presented with deidentified illustrations. Implications for services, research, and policy are discussed.

In and out of schizophrenia: Activation and deactivation of the negative and positive schemas

Theorists, clinicians, and investigators have attempted to find a common source for the negative and positive symptoms of schizophrenia. We propose that a unified theory, based on a common cognitive structure not only has explanatory value, but can serve as a framework for a psychotherapeutic intervention. Specifically, we propose that the cognitive triad - the negative view of the self, others, and the future - is the source of the content for the negative and positive symptoms. We report literature supporting the relationship between each facet of the negative triad and each of the key symptoms: expressive negative symptoms, delusions, and verbal hallucinations. We conclude that the literature supports the validity of the cognitive model of negative and positive symptoms. The cognitive model furthers the understanding of the positive and negative symptoms of schizophrenia, and we describe how this provides a framework for a psychotherapeutic intervention.

Neurocognitive and theory of mind deficits and poor social competence in schizophrenia: The moderating role of social disinterest attitudes

Neurocognitive and theory of mind deficits, dysfunctional attitudes, and negative symptoms have all been linked to poor functioning in schizophrenia, but interactions among these factors have not been extensively examined. We investigated whether dysfunctional attitudes (e.g., defeatist performance beliefs and social disinterest attitudes) moderated associations between neurocognition and theory of mind and poor everyday functioning and social competence in 146 participants with schizophrenia. We examined whether cognitive deficits are more likely to influence functioning in participants with more severe dysfunctional attitudes. Social disinterest, but not defeatist performance, attitudes were found to moderate associations between cognitive deficits and social competence but not everyday functioning, such that neurocognition and theory of mind deficits were only associated with poorer social competence in participants with more severe social disinterest attitudes. In contrast, no significant moderation effects were found for defeatist performance beliefs. Findings indicate that deficits in abilities were less likely to impact social competence in participants with greater interest in socializing. It may be that greater motivation for socializing engenders increased practice and engagement in social interactions, which then leads to greater social competence despite poor cognitive abilities. Treatments that target social disinterest attitudes may lead to greater social competence and engagement.

What accounts for poor functioning in people with schizophrenia: a re-evaluation of the contributions of neurocognitive v. attitudinal and motivational factors

BACKGROUND

Neurocognitive deficits are often seen as core features of schizophrenia, and as primary determinants of poor functioning. Yet, our clinical observations suggest that individuals who score within the impaired range on standardized tests can reliably perform better in complex real-world situations, especially when performance is embedded within a positive socio-affective context.

METHODS

We analyzed literature on the influence of non-neurocognitive factors on test performance in order to clarify their contributions.

RESULTS

We identified seven non-neurocognitive factors that significantly contribute to neurocognitive test performance: avolition, dysfunctional attitudes, effort, stress, negative emotions, asociality, and disorganized symptoms. We then proposed an alternative model based on dysfunctional (e.g. defeatist) attitudes and their consequences for motivation and sustained task engagement. We demonstrated that these factors account for substantial variance in negative symptoms, neurocognitive test performance, and functional outcomes. We then demonstrated that recovery-oriented cognitive therapy - which is derived from this alternative model and primarily targets dysfunctional beliefs - has been successful in the treatment of low functioning individuals with schizophrenia.

CONCLUSION

The contributions of neurocognitive impairments to poor real-world functioning in people with schizophrenia may be overstated in the literature, and may even be limited relative to non-neurocognitive factors. We offer suggestions for further research to more precisely quantify the contributions of attitudinal/motivation v. neurocognitive factors in schizophrenia.

A test of the cognitive model of negative symptoms: Associations between defeatist performance beliefs, self-efficacy beliefs, and negative symptoms in a non-clinical sample

The cognitive model of negative symptoms posits that defeatist performance beliefs-overgeneralized negative beliefs about one's ability to successfully perform tasks-contribute to the development and maintenance of negative symptoms. However, a conceptually similar construct, reduced generalized self-efficacy-diminished confidence in one's ability to effectively complete or respond to new or challenging tasks and situations-has also been linked to negative symptoms. To identify which beliefs might be most important to target to reduce negative symptoms, we examined: 1) the association between defeatist performance and self-efficacy beliefs and 2) which beliefs are more strongly associated with negative symptoms in a non-clinical sample of young adults (N = 941). Analyses revealed a significant, medium-sized correlation between defeatist performance and self-efficacy beliefs. Both beliefs types were significantly associated with negative symptoms, but defeatist performance beliefs were more strongly related to negative symptoms than self-efficacy beliefs. Defeatist performance and self-efficacy beliefs appear to be distinct yet overlapping constructs. Findings support the cognitive model and indicate that defeatist performance beliefs may have a greater role in the manifestation of negative symptoms than self-efficacy beliefs. Thus, defeatist performance beliefs may be a uniquely promising treatment target for reducing or preventing negative symptoms.

Improvement in Negative Symptoms and Functioning in Cognitive-Behavioral Social Skills Training for Schizophrenia: Mediation by Defeatist Performance Attitudes and Asocial Beliefs

Psychosocial interventions have significant but modest impact on negative symptoms and functioning in schizophrenia. Identifying mechanisms of change in these interventions can inform treatment targets to strengthen these interventions. A number of studies have found associations between dysfunctional attitudes negative symptoms and functioning in schizophrenia. We previously found improvement in experiential negative symptoms and functioning in cognitive-behavioral social skills training (CBSST) in participants with schizophrenia (N = 149), and the present study examined whether improvements in CBSST in that trial were mediated by the group effect on defeatist performance attitudes and asocial beliefs. In multilevel mediation analyses, the effect of treatment group on experiential negative symptoms and functioning was mediated prospectively through defeatist attitudes but asocial beliefs only mediated effects on experiential negative symptoms. The findings suggest that cognitive-behavioral therapy interventions that target dysfunctional attitudes can lead to improvement in negative symptoms and functioning in schizophrenia.

Rapid improvement in beliefs, mood, and performance following an experimental success experience in an analogue test of recovery-oriented cognitive therapy

BACKGROUND

Negative symptoms significantly contribute to disability and lack of community participation for low functioning individuals with schizophrenia. Cognitive therapy has been shown to improve negative symptoms and functional outcome in this population. Elucidation of the mechanisms of the therapy would lead to a better understanding of negative symptoms and the development of more effective interventions to promote recovery. The objective of this study was to determine (1) whether guided success at a card-sorting task will produce improvement in defeatist beliefs, positive beliefs about the self, mood, and card-sorting performance, and (2) whether these changes in beliefs and mood predict improvements in unguided card-sorting.

METHODS

Individuals with schizophrenia having prominent negative symptoms and impaired neurocognitive performance (N = 35) were randomized to guided success (n = 19) or a control (n = 16) condition.

RESULTS

Controlling for baseline performance, the experimental group performed significantly better, endorsed defeatist beliefs to a lesser degree, reported greater positive self-concept, and reported better mood than the control condition immediately after the experimental session. A composite index of change in defeatist beliefs, self-concept, and mood was significantly correlated with improvements in card-sorting.

CONCLUSIONS

This analogue study supports the rationale of cognitive therapy and provides a general therapeutic model in which experiential interventions that produce success have a significant immediate effect on a behavioral task, mediated by changes in beliefs and mood. The rapid improvement is a promising indicator of the responsiveness of this population, often regarded as recalcitrant, to cognitively-targeted behavioral interventions.

Metacognition Is Necessary for the Emergence of Motivation in People With Schizophrenia Spectrum Disorders: A Necessary Condition Analysis

Metacognition deficits are a putative cause of reduced motivation in people with schizophrenia spectrum disorders. However, it is unclear whether certain levels of metacognition are necessary for motivation to emerge. This study used a Necessary Condition Analysis to test whether metacognition was necessary for the presence of motivation and to identify the minimum level of metacognition necessary for high motivation to be possible in people with schizophrenia spectrum disorders (N = 175). Participants completed clinician-rated measures of metacognition and motivation. Necessary Condition Analysis revealed that metacognition is a necessary condition for motivation and that high levels of motivation were only possible, although not guaranteed, when at least a basic level of metacognition was present. The findings suggest that metacognition is a necessary building block for the development of motivation. Results suggest that targeting metacognition may be essential for improving motivation among people with schizophrenia spectrum disorders who do not meet this metacognition threshold.
