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

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). 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. 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. 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.

Defeatist performance beliefs in individuals with recent-onset schizophrenia: Relationships with cognition and negative symptoms

BackgroundThe cognitive model of negative symptoms of schizophrenia suggests that defeatist performance beliefs (DPB), or overgeneralized negative beliefs about one's performance, are an intermediary variable along the pathway from impaired neurocognitive performance to negative symptoms and functioning in daily life. Although reliable associations between these variables have been established in chronic schizophrenia, less is known about the nature of these relationships in recent-onset schizophrenia (ROSz). This current study tested the associations between DPB and variables in the cognitive model (neurocognitive performance, negative symptoms, functioning) as well as mediation by DPB of the association between neurocognitive performance and negative symptoms in ROSz. MethodsA total of 52 participants (32 adults with ROSz and 20 non-psychiatric healthy comparators; HC) completed in-lab measures of neurocognitive performance, self-reported defeatist performance beliefs, and clinician administered measures of negative symptoms and functional outcome. Bivariate relationships among these variables were tested with Pearson correlations. Bootstrapped regression analyses were conducted to test the strength of the indirect effect of neurocognitive performance on negative symptoms through DPB. ResultsDefeatist performance beliefs were significantly elevated in ROSz, and were associated with neurocognitive performance, negative symptoms, and functional outcome as predicted by the cognitive model. There was a significant indirect effect of neurocognition on experiential negative symptoms through DPB, indicating DPB are a partial mediator of the relationship between neurocognitive performance and negative symptoms. ConclusionThese findings are consistent with the cognitive model of negative symptoms and extend previous findings in both ROSz and established schizophrenia. Specifically, these data demonstrate that DPB are elevated among ROSz and the associations with neurocognition and clinical outcomes (e.g., negative symptoms and functioning) are of similar magnitude to those reported in chronic schizophrenia. DPB may therefore be a viable treatment target in the early course of illness.

Pupillary responses as a biomarker of cognitive effort and the impact of task difficulty on reward processing in schizophrenia

Negative symptoms of schizophrenia robustly predict functional outcomes but remain relatively resistant to available treatments. Better measures of negative symptoms, especially motivational deficits, are needed to better understand these symptoms and improve treatment development. Recent research shows promise in linking behavioral effort tasks to motivational negative symptoms, reward processing deficits, and defeatist attitudes, but few studies account for individual or group (patient v. control) differences in cognitive ability to perform the tasks. Individuals with poorer abilities might be less motivated to perform tasks because they find them more difficult to perform. This study used a personalized digit span task to control task difficulty while measuring task effort via pupillary responses (greater dilation indicates greater cognitive effort) at varying monetary rewards ($1 & $2). Participants with schizophrenia (N = 34) and healthy controls (N = 41) performed a digit span task with personalized max span lengths and easy (max− 2 digits) and overload (max+ 2 digits) conditions. Consistent with many studies, pupillary responses (cognitive effort) increased with greater difficulty until exceeding capacity. A similar pattern of reward responsivity was seen in both groups, such that greater reward increased dilation (effort) comparably for both groups when difficulty was within capacity. Neither patients nor controls exerted increased effort for greater reward when difficulty exceeded capacity. In patients, positive relationships were found between pupil dilation and defeatist performance beliefs if task difficulty was within capacity; a relationship that reversed if the task was too difficult. The findings demonstrate the importance of accounting for cognitive capacity and task difficulty when evaluating motivation and reward sensitivity and illustrate the utility of pupillary responses as an objective measure of effort in schizophrenia.

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.

Two and five-factor models of negative symptoms in schizophrenia are differentially associated with trait affect, defeatist performance beliefs, and psychosocialfunctioning.

Recent factor analytic evidence supports both two-factor (motivation and pleasure, MAP; diminished expression, EXP) and five-factor (anhedonia, asociality, avolition, blunted affect, alogia) conceptualizations of negative symptoms. However, it is unclear whether these two conceptualizations of the latent structure of negative symptoms have differential associations with external correlates. The current study evaluated external correlates of the two- and five-factor structures by examining associations with variables known to have critical relations with negative symptoms: trait affect, defeatist performance beliefs, neurocognition, and community-based psychosocial functioning. Participants included a total of 245 outpatients diagnosed with schizophrenia who were rated on the Brief Negative Symptom Scale and completed a battery of additional measures during periods of clinical stability. These additional measures included the Positive and Negative Affect Schedule, Defeatist Performance Beliefs scale, MATRICS Consensus Cognitive Battery, and Level of Function Scale. Pearson correlations indicated differential patterns of associations between the BNSS scores and the external correlates. Support for the two-factor model was indicated by a stronger association of MAP with positive affect and psychosocial functioning, compared to EXP with neurocognition. Significance tests examining a differential magnitude of associations showed that the two-dimension negative symptom structure masked unique correlational relationships among the five negative symptom domains with neurocognition and social/vocational community functioning and captured unique patterns of correlation with trait affect. Support for the five-factor model was shown by a stronger association between Blunted Affect with Attention/Vigilance, and stronger associations between Avolition, Anhedonia, and Asociality with psychosocial functioning. Results offer support for both the two-dimension and five-domain model of negative symptoms as well as a hierarchical two-dimensions-five-domains model of negative symptoms. Findings may have implications for diagnostic criteria and descriptions of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5), as well as possible treatment targets of negative symptoms.

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.

Two Factors, Five Factors, or Both? External Validation Studies of Negative Symptom Dimensions in Schizophrenia.

Negative symptom studies frequently use single composite scores as indicators of symptom severity and as primary endpoints in clinical trials. Factor analytic and external validation studies do not support this practice but rather suggest a multidimensional construct. The current study used structural equation modeling (SEM) to compare competing dimensional models of negative symptoms to determine the number of latent dimensions that best capture variance in biological, psychological, and clinical variables known to have associations with negative symptoms. Three independent studies (total n = 632) compared unidimensional, two-factor, five-factor, and hierarchical conceptualizations of negative symptoms in relation to cognition, psychopathology, and community functioning (Study 1); trait emotional experience and defeatist performance beliefs (Study 2); and glutamate and gamma-aminobutyric acid levels in the anterior cingulate cortex quantified using proton magnetic resonance spectroscopy (Study 3). SEM favored the five-factor and hierarchical models over the unidimensional and two-factor models regardless of the negative symptom measure or external validator. The five dimensions-anhedonia, asociality, avolition, blunted affect, and alogia-proved vital either as stand-alone domains or as first-order domains influenced by second-order dimensions-motivation and pleasure and emotional expression. The two broader dimensions sometimes masked important associations unique to the five narrower domains. Avolition, anhedonia, and blunted affect showed the most domain-specific associations with external variables across study samples. Five domains and a hierarchical model reflect the optimal conceptualization of negative symptoms in relation to external variables. Clinical trials should consider using the two dimensions as primary endpoints and the five domains as secondary endpoints.

Bullying and social functioning, schemas, and beliefs among youth at clinical high risk for psychosis.

Individuals at clinical high-risk (CHR) for psychosis experience high rates of bullying. There is little research on the differences between CHR who did and did not experience bullying. However, there is evidence that bullying may be related to negative schemas and social impairment. To examine differences in core schemas, asocial and defeatist beliefs, and social functioning between those who did and did not report bullying experiences in a large sample of CHR individuals. We hypothesized that bullying in CHR youth would be associated with poorer social functioning, increased maladaptive beliefs, and negative core schemas. CHR participants (N=203) were split into those who did and did not report experiencing bullying. The two groups were compared on demographic characteristics, social functioning, and belief variables, using the Brief Core Schemas Scale, the Asocial Beliefs Scale, the Defeatist Performance Attitudes Scale, and the First Episode Social Functioning Scale. 72.9% reported experiencing bullying. These participants had greater severity of negative schemas about others and asocial and defeatist performance beliefs, and lower social functioning scores. Prevalence of bullying among CHR participants is high. Bullying may be a risk factor for increased asocial and defeatist beliefs, negative core schemas, and poor social functioning. Targeting maladaptive schemas and beliefs during treatment may serve to improve functional outcomes in this group.

Apathy in patients with schizophrenia: Treatment perspectives

Apathy occurs in many neuropsychiatric disorders and is a central negative symptom of schizophrenia. Apathy has severe functional consequences for patients with schizophrenia and the development of evidence-based treatments is a major challenge. There is now increasing evidence that dysfunctions in reward processing underly apathy, in particular regarding reward anticipation, cost-benefit computation and reward learning. In addition, metacognitive processes such as defeatist performance beliefs modulate reward processing. Psychological interventions for negative symptoms target these processes. While the evidence for cognitive-behavioral therapy for negative symptoms remains limited, recent findings suggest that specifically targeting reward-related dysfunctions may improve efficacy of these interventions. On the neurobiological level, there is now considerable evidence that a dysregulation of the dopaminergic reward system is related to reward processing dysfunctions. Regarding pharmacological treatment approaches, psychostimulants have successfully been used for apathy in dementia to target the reward system. Pro-dopaminergic drugs to target apathy in schizophrenia seem to be safer than anticipated, but their efficacy remains to be established. At the current state of knowledge, there is no evidence-based treatment that specifically targets apathy in patients with schizophrenia today. However, there are encouraging results from research inspired by basic research in neuroscience and clinical research in patients with other neuropsychiatric disorders.DisclosureSK has received royalties from Schuhfried (Austria) for cognitive test and training software.

Much of the Neurocognitive Impairment in Schizophrenia is Due to Factors Other Than Schizophrenia Itself: Implications for Research and Treatment

Abstract Patients with schizophrenia perform worse on neuropsychological tasks than controls. While most experts ascribe poor performance to neurocognitive impairment, an emerging literature is identifying important nonspecific mediators of neurocognitive test performance, some of which can be accounted for in trials (eg, motivation, effort, defeatist performance beliefs, stress, anxiety, physical inactivity). Other factors are harder, if not impossible, to control when patients are compared to non-clinical participants (eg, hospitalization, medication effects, distraction due to positive symptoms). Effect sizes of neurocognitive performance differences are usually not adjusted for these confounders, and the level of neurocognitive impairment due to schizophrenia is thus likely exaggerated. We suggest some ways for researchers to account for the effects of these mediators. Secondary influences that negatively affect neurocognitive performance should not be treated as mere noise. They give important insight into causal mechanisms and may inform more effective treatments that go beyond cognitive remediation.

Defeatist performance beliefs in individuals at clinical high-risk for psychosis and outpatients with chronic schizophrenia.

Prior studies indicate that defeatist performance beliefs (DPBs) are elevated in those in the chronic phase of schizophrenia (SZ) and associated with negative symptoms, functional outcome and neurocognitive impairment. However, it is unclear whether these same patterns of results hold in participants at clinical high-risk (CHR) for psychosis. Two studies were conducted to determine whether prior results in SZ could be replicated and extended to CHR. Participants included 184 healthy controls (CN) and 186 outpatients with chronic SZ for Study 1, and 30 CN and 35 CHR in Study 2. In both studies, participants completed the DPB scale and measures of negative symptoms, psychosocial functioning and neurocognition. Both chronic SZ and CHR participants had elevated DPBs compared to CN (p's < .01). In SZ, higher DPBs were associated with greater negative symptoms (r's=.31-.37, p's < .01), poorer social functioning and impaired social cognition (r = -.40, P < .001). In CHR, greater DPBs were associated with poorer social functioning (r = -.52, P < .05) and impairments in the neurocognitive domains of reasoning (r = -.48, P < .05) and processing speed (r = -.41, P < .05). Models testing whether DPBs mediated links between negative symptoms and functioning, negative symptoms and cognition and cognition and functioning were nonsignificant in SZ and CHR samples. Findings generally provide support for the cognitive model of negative symptoms and functioning and suggest that DPBs are an important clinical target across phases of psychotic illness.

Defeatist performance beliefs in college students: Transdiagnostic associations with symptoms and daily goal-directed behavior

Defeatist performance beliefs are prevalent and linked to decreased motivation in people with psychological disorders. In this study, we investigated whether defeatist performance beliefs were associated with transdiagnostic psychopathology risk in people with no history of formal diagnosis and whether defeatist performance beliefs impacted engagement in daily goal-directed behavior. One hundred and two college students completed self-report measures of defeatist performance beliefs and risk for depression, mania, and psychosis. Sixty-one of these participants were randomly selected to identify a goal and complete daily surveys about their actual and expected goal progress, effort expenditure, experienced pleasure, and difficulty of goal pursuit. We found that greater defeatist performance beliefs were associated with higher risk for depression, mania, and psychosis. Using multilevel modeling, we found that greater defeatist performance beliefs predicted less goal progress, effort expenditure, and pleasure from goal pursuit. Together, these findings suggest that defeatist performance beliefs may impact goal-directed behavior in healthy people with no reported psychiatric history. Interventions targeting defeatist performance beliefs may have utility for actual goal-directed behavior in many people, regardless of psychiatric status.

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.

Single-Session Mobile-Augmented Intervention in Serious Mental Illness: A Three-Arm Randomized Controlled Trial.

Psychosocial interventions for serious mental illness are resource intensive and poorly accessible. Brief interventions (eg, single session) that are augmented by follow-on automated mobile health intervention may expand treatment access. This was a randomized single-blind controlled trial with 255 individuals diagnosed with schizophrenia or bipolar disorder. Participants were randomized to one of three conditions: CBT2go, which combined one individual session of cognitive behavioral therapy with automated thought challenging/adaptive behavior delivered through mobile devices; Self-Monitoring (SM), which combined single-session illness psychoeducation with self-monitoring of symptoms; and treatment-as-usual (TAU). Participants were assessed at baseline, 6 weeks (midpoint), 12 weeks (posttreatment), and 24 weeks (follow-up) with our primary outcome global psychopathology (Brief Psychiatric Rating Scale-expanded version [BPRS-24]), and secondary outcomes community functioning (Specific Level of Function; SLOF) and defeatist performance beliefs (DPBs). We also collected data on adverse events. Outcome analyses on the primary outcome, BPRS Total score, indicated a significant time (0-24 wk) by group interaction with significant but modest improvement comparing two active conditions (CBT2go and SM) relative to TAU. Effects of CBT2go were not different from SM. There was a significant time × group interaction with better SLOF scores in CBT2go across 24 weeks, but not in SM. There were no time-by-group effects on DPBs. DPBs decreased in the CBT2go condition but not in SM. These results indicated that single intervention augmented by mobile intervention was feasible and associated with small yet sustained effects on global psychopathology and, when inclusive of CBT, community function compared with usual care.

Treatment Implications of Situational Variability in Cognitive and Negative Symptoms of Schizophrenia.

Cognitive impairments and negative symptoms in schizophrenia are associated with poorer outcomes and are typically resistant to pharmacological interventions. However, these features can vary dramatically in their level of expression, and they can improve as a function of external context (by providing performance-contingent incentives and a more stimulating environment) and internal context (by challenging defeatist performance beliefs and by reducing stress and improving physical health). This Open Forum briefly reviews some of this evidence for the situational variability of cognitive impairments and negative symptoms in schizophrenia and highlights psychosocial treatments that capitalize on this variability. The authors' goals are to stimulate development and implementation of interventions and to show practitioners how they can achieve more positive outcomes in their clinical work with what is often seen as a hard-to-treat population.

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.

T27. DYSFUNCTIONAL ATTITUDES IN ADOLESCENTS WITH EARLY-ONSET PSYCHOSIS: PRELIMINARY RESULTS

BackgroundDysfunctional attitudes such as defeatist performance beliefs (DPB) and asocial beliefs (AB) have been linked to negative symptoms and functional outcome in chronic schizophrenia (Campellone et al., 2016; Grant and Beck, 2010) and in adults with recent onset schizophrenia (Ventura et al., 2014). Adolescents with early-onset psychosis (EOP) are at major risk of having persistent negative symptoms (Puig et al., 2017) but no previous study has examined dysfunctional attitudes in this population. We aimed: (1) to examine if more DPB and AB were present in adolescents with EOP compared with normal controls, and (2) to study the relationships between DPB and AB with symptoms and functioning.MethodsSample: 15 adolescents with EOP (11♀, age=15.33 ± 1.23) and 10 healthy controls (8♀, age=15.60 ± 1.51), participants in a trial about cognitive and behavioral social skills treatment in EOP developing in Hospital Clínic of Barcelona (baseline data). Patients were under antipsychotic meds. Inclusion criteria: having an early-onset schizophrenia spectrum disorder diagnosed between 9–18 years-old (schizophrenia, schizoaffective disorder, psychosis n.o.s.); being within the 5 first years after the disease onset; clinical stability. Exclusion criteria: IQ<70; comorbid substance dependence disorder; neurological disorders. Instruments: PANSS (Kay et al., 1987), Calgary Depression Scale (CDS, Addington et al., 1990), Children’s Global Assessment Scale (C-GAS, Shaffer et al., 1983), Social and Role Functioning Scales (GF:S, GF:R, Cornblatt et al., 2007), Life Skills Profile - Adolescent version (Puig et al., 2013), Dysfunctional Attitudes Scale - Spanish version (DAS, Sanz et al., 1993); Asocial Beliefs Scale (Grant and Beck, 2010). DPB was extracted from the DAS scale following Beck et al. (2013). Groups were compared with T-test or Chi-square tests. Pearson correlations were computed for examining relationships between variables.ResultsEOP and control groups were homogeneous in age (t=-0.49, p=0.632) and sex (X2=0.15, p=0.702). All subjects were living with their parents. Family SES was lower in EOP group (X2=10.69, p=0.030). All subjects but one patient were studying although patients had repeated more courses (t=4.00, p=0.001). EOP subjects had a predominance of negative symptoms (positive symptoms=14.07 ± 3.85; negative symptoms=23.50 ± 13.79; general symptoms=31.86 ± 7.28). Mean score of CDS in EOP was low (3.77 ± 4.76). EOP group had lower scores in all functional measures than controls (C-GAS: 51.14 ± 9.38 vs 93.70 ± 4.45, GF:S: 5.71 ± 1.07 vs 9.00 ± 0.47, GF:R: 5.21 ± 1.12 vs 8.80 ± 0.42, LSP: 67.64 ± 12.30 vs 44.13 ± 3.60; t>6.67, p<0.001). Regarding dysfunctional attitudes, EOP group had higher scores in dysfunctional attitudes scales than healthy controls (DPB: 55.60 ± 19.57 vs 33.00 ± 9.37, AB: 6.67 ± 3.42 vs 3.00 ± 2.11; t>3.02, p<0.006). In EOP, DPB and AB scores were negatively correlated with functioning (DPB: C-GAS r=-0.60, GF:S r=-0.66, GF:R r=-0.66, LSP r=0.65; p<0.002; AB: C-GAS r=-0.45, GF:S r=-0.55, GF:R r=-0.49, LSP r=0.53; p<0.029). No significant correlation were found between dysfunctional attitudes and negative symptoms in EOP.DiscussionThese preliminary results showed that adolescents with EOP had higher levels of dysfunctional attitudes than controls. Accordantly to recent literature, defeatists performance beliefs and asocial beliefs were correlated with poorer functioning. However, dysfunctional attitudes were not associated with negative symptoms. It might be that dysfunctional attitudes do not contribute to negative symptoms but in functional outcome in youngs with EOP although larger samples are required.

Understanding the Association Between Negative Symptoms and Performance on Effort-Based Decision-Making Tasks: The Importance of Defeatist Performance Beliefs.

Effort-based decision-making paradigms are increasingly utilized to gain insight into the nature of motivation deficits. Research has shown associations between effort-based decision making and experiential negative symptoms; however, the associations are not consistent. The current study had two primary goals. First, we aimed to replicate previous findings of a deficit in effort-based decision making among individuals with schizophrenia on a test of cognitive effort. Second, in a large sample combined from the current and a previous study, we sought to examine the association between negative symptoms and effort by including the related construct of defeatist beliefs. The results replicated previous findings of impaired cognitive effort-based decision making in schizophrenia. Defeatist beliefs significantly moderated the association between negative symptoms and effort-based decision making such that there was a strong association between high negative symptoms and deficits in effort-based decision making, but only among participants with high levels of defeatist beliefs. Thus, our findings suggest the relationship between negative symptoms and effort performance may be understood by taking into account the role of defeatist beliefs, and finding that might explain discrepancies in previous studies.

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

Evidence for a relationship between neurocognition and functional outcome in important areas of community living is robust in serious mental illness research. Dysfunctional attitudes (defeatist performance beliefs and asocial beliefs) have been identified as intervening variables in this causal chain. This study seeks to expand upon previous research by longitudinally testing the link between neurocognition and community participation (i.e. time in community-based activity) through dysfunctional attitudes and motivation. Adult outpatients with serious mental illness (N = 175) participated, completing follow-up assessments approximately 6 months after initial assessment. Path analysis tested relationships between baseline neurocognition, emotion perception, functional skills, dysfunctional attitudes, motivation, and outcome (i.e. community participation) at baseline and follow-up. Path models demonstrated two pathways to community participation. The first linked neurocognition and community participation through functional skills, defeatist performance beliefs, and motivation. A second pathway linked asocial beliefs and community participation, via a direct path passing through motivation. Model fit was excellent for models predicting overall community participation at baseline and, importantly, at follow-up. The existence of multiple pathways to community participation in a longitudinal model supports the utility of multi-modal interventions for serious mental illness (i.e. treatment packages that build upon individuals' strengths while addressing the array of obstacles to recovery) that feature dysfunctional attitudes and motivation as treatment targets.

P.1.k.002 - (Mis)use of prescribed stimulants in the medical student community: Motives and behaviors. A population-based cross-sectional study

The cognitive model of poor functioning in schizophrenia posits that defeatist performance beliefs—overgeneralized negative beliefs about one's ability to perform tasks—develop prior to the onset of psychosis and contribute to the development and maintenance of negative symptoms and poor functioning. Although several studies with schizophrenia samples have provided support for the model, there is a paucity of research investigating these beliefs in individuals with schizotypy—those exhibiting traits reflecting a putative genetic liability for schizophrenia. This study had two aims: to examine whether defeatist performance beliefs (1) are elevated in schizotypy compared to controls and (2) are associated with decreased quality of life and working memory and increased negative but not positive schizotypy traits in the schizotypy group.Schizotypy (n = 48) and control (n = 53) groups completed measures of schizotypy traits, defeatist performance beliefs, quality of life, and working memory.Analyses revealed that the schizotypy group reported significantly more defeatist performance beliefs than the control group. Within the schizotypy group, increased defeatist performance beliefs were significantly associated with greater negative schizotypy traits and lower quality of life. No significant associations were observed between defeatist performance beliefs and positive schizotypy traits and working memory.Results generally support the theoretical validity of the cognitive model of poor functioning in schizophrenia and suggest that elevated defeatist performance beliefs may contribute to the manifestation of subclinical negative symptom traits and reduced quality of life among those with a latent vulnerability for schizophrenia.
